With the proliferation of AI/ML enabled technologies to deliver business value, the need to protect data privacy and secure AI/ML applications from security risks is paramount. An AI governance framework model like the NIST AI RMF to enable business innovation and manage risk is just as important as adopting guidelines to secure AI. Responsible AI starts with securing AI by design and securing AI with Zero Trust architecture principles. Vulnerabilities in ChatGPT A recent discovered vulnerability found in version gpt-3.5-turbo exposed identifiable information. The vulnerability was reported in the news late November 2023. By repeating a particular word continuously to the chatbot it triggered the vulnerability. A group of security researchers with Google DeepMind, Cornell University, CMU, UC Berkeley, ETH Zurich, and the University of Washington studied the “extractable memorization” of training data that an adversary can extract by querying a ML model without prior knowledge of the training dataset. The researchers’ report show an adversary can extract gigabytes of training data from open-source language models. In the vulnerability testing, a new developed divergence attack on the aligned ChatGPT caused the model to emit training data 150 times higher. Findings show larger and more capable LLMs are more vulnerable to data extraction attacks, emitting more memorized training data as the volume gets larger. While similar attacks have been documented with unaligned models, the new ChatGPT vulnerability exposed a successful attack on LLM models typically built with strict guardrails found in aligned models. This raises questions about best practices and methods in how AI systems could better secure LLM models, build training data that is reliable and trustworthy, and protect privacy. U.S. and UK’s Bilateral cybersecurity effort on securing AI The US Cybersecurity Infrastructure and Security Agency (CISA) and UK’s National Cyber Security Center (NCSC) in cooperation with 21 agencies and ministries from 18 other countries are supporting the first global guidelines for AI security. The new UK-led guidelines for securing AI as part of the U.S. and UK’s bilateral cybersecurity effort was announced at the end of November 2023. The pledge is an acknowledgement of AI risk by nation leaders and government agencies worldwide and is the beginning of international collaboration to ensure the safety and security of AI by design. The Department of Homeland Security (DHS) CISA and UK NCSC joint guidelines for Secure AI system Development aims to ensure cybersecurity decisions are embedded at every stage of the AI development lifecycle from the start and throughout, and not as an afterthought. Securing AI by design Securing AI by design is a key approach to mitigate cybersecurity risks and other vulnerabilities in AI systems. Ensuring the entire AI system development lifecycle process is secure from design to development, deployment, and operations and maintenance is critical to an organization realizing its full benefits. The guidelines documented in the Guidelines for Secure AI System Development aligns closely to software development life cycle practices defined in the NSCS’s Secure development and deployment guidance and the National Institute of Standards and Technology (NIST) Secure Software Development Framework (SSDF). The 4 pillars that embody the Guidelines for Secure AI System Development offers guidance for AI providers of any systems whether newly created from the ground up or built on top of tools and services provided from | Tool Vulnerability Threat Mobile Medical Cloud Technical | ChatGPT | ★★ |

2024-03-05 19:03:47 | Rester en avance sur les acteurs de la menace à l'ère de l'IA Staying ahead of threat actors in the age of AI (lien direct) |
## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a | Ransomware Malware Tool Vulnerability Threat Studies Medical Technical | APT 28 ChatGPT APT 4 | ★★ |

#### Description Recorded Future\'s Insikt Group has discovered new infrastructure related to the operators of Predator, a mercenary mobile spyware. The infrastructure is believed to be in use in at least eleven countries, including Angola, Armenia, Botswana, Egypt, Indonesia, Kazakhstan, Mongolia, Oman, the Philippines, Saudi Arabia, and Trinidad and Tobago. Despite being marketed for counterterrorism and law enforcement, Predator is often used against civil society, targeting journalists, politicians, and activists. The use of spyware like Predator poses significant risks to privacy, legality, and physical safety, especially when used outside serious crime and counterterrorism contexts. The Insikt Group\'s research identified a new multi-tiered Predator delivery infrastructure, with evidence from domain analysis and network intelligence data. Despite public disclosures in September 2023, Predator\'s operators have continued their operations with minimal changes. Predator, alongside NSO Group\'s Pegasus, remains a leading provider of mercenary spyware, with consistent tactics, techniques, and procedures over time. As the mercenary spyware market expands, the risks extend beyond civil society to anyone of interest to entities with access to these tools. Innovations in this field are likely to lead to more stealthy and comprehensive spyware capabilities. #### Reference URL(s) 1. https://www.recordedfuture.com/predator-spyware-operators-rebuild-multi-tier-infrastructure-target-mobile-devices #### Publication Date March 1, 2024 #### Author(s) Insikt Group |

2024-02-29 11:00:00 | Gouvernance de l'IA et préservation de la vie privée AI governance and preserving privacy (lien direct) |
AT&T Cybersecurity featured a dynamic cyber mashup panel with Akamai, Palo Alto Networks, SentinelOne, and the Cloud Security Alliance. We discussed some provocative topics around Artificial Intelligence (AI) and Machine Learning (ML) including responsible AI and securing AI. There were some good examples of best practices shared in an emerging AI world like implementing Zero Trust architecture and anonymization of sensitive data. Many thanks to our panelists for sharing their insights. Before diving into the hot topics around AI governance and protecting our privacy, let’s define ML and GenAI to provide some background on what they are and what they can do along with some real-world use case examples for better context on the impact and implications AI will have on our future. GenAI and ML Machine Learning (ML) is a subset of AI that relies on the development of algorithms to make decisions or predictions based on data without being explicitly programmed. It uses algorithms to automatically learn and improve from experience. GenAI is a subset of ML that focuses on creating new data samples that resemble real-world data. GenAI can produce new and original content through deep learning, a method in which data is processed like the human brain and is independent of direct human interaction. GenAI can produce new content based on text, images, 3D rendering, video, audio, music, and code and increasingly with multimodal capabilities can interpret different data prompts to generate different data types to describe an image, generate realistic images, create vibrant illustrations, predict contextually relevant content, answer questions in an informational way, and much more. Real world uses cases include summarizing reports, creating music in a specific style, develop and improve code faster, generate marketing content in different languages, detect and prevent fraud, optimize patient interactions, detect defects and quality issues, and predict and respond to cyber-attacks with automation capabilities at machine speed. Responsible AI Given the power to do good with AI - how do we balance the risk and reward for the good of society? What is an organization’s ethos and philosophy around AI governance? What is the organization’s philosophy around the reliability, transparency, accountability, safety, security, privacy, and fairness with AI, and one that is human-centered? It\'s important to build each of these pillarsn into an organization\'s AI innovation and business decision-making. Balancing the risk and reward of innovating AI/ML into an organization\'s ecosystem without compromising social responsibility and damaging the company\'s brand and reputation is crucial. At the center of AI where personal data is the DNA of our identity in a hyperconnected digital world, privacy is a top priority. Privacy concerns with AI In Cisco’s 2023 consumer privacy survey, a study of over 2600 consumers in 12 countries globally, indicates consumer awareness of data privacy rights is continuing to grow with the younger generations (age groups under 45) exercising their Data Subject Access rights and switching providers over their privacy practices and policies. Consumers support AI use but are also concerned. With those supporting AI for use: 48% believe AI can be useful in improving their lives 54% are willing to share anonymized personal data to improve AI products AI is an area that has some work to do to earn trust 60% of respondents believe the use of AI by organizations has already eroded trust in them 62% reported concerns about the business use of AI 72% of respondents indicated that having products and solutions aud | Studies Prediction Cloud Technical | ★★ | |

We often-and justifiably-associate cyberattacks with technical exploits and ingenious hacks. But the truth is that many breaches occur due to the vulnerabilities of human behavior. That\'s why Proofpoint has gathered new data and expanded the scope of our 2024 State of the Phish report. Traditionally, our annual report covers the threat landscape and the impact of security education. But this time, we\'ve added data on risky user behavior and their attitudes about security. We believe that combining this information will help you to: Advance your cybersecurity strategy Implement a behavior change program Motivate your users to prioritize security This year\'s report compiles data derived from Proofpoint products and research, as well as from additional sources that include: A commissioned survey of 7,500 working adults and 1,050 IT professionals across 15 countries 183 million simulated phishing attacks sent by Proofpoint customers More than 24 million suspicious emails reported by our customers\' end users To get full access to our global findings, you can download your copy of the 2024 State of the Phish report now. Also, be sure to register now for our 2024 State of the Phish webinar on March 5, 2024. Our experts will provide more insights into the key findings and answer your questions in a live session. Meanwhile, let\'s take a sneak peek at some of the data in our new reports. Global findings Here\'s a closer look at a few of the key findings in our tenth annual State of the Phish report. Survey of working adults In our survey of working adults, about 71%, said they engaged in actions that they knew were risky. Worse, 96% were aware of the potential dangers. About 58% of these users acted in ways that exposed them to common social engineering tactics. The motivations behind these risky actions varied. Many users cited convenience, the desire to save time, and a sense of urgency as their main reasons. This suggests that while users are aware of the risks, they choose convenience. The survey also revealed that nearly all participants (94%) said they\'d pay more attention to security if controls were simplified and more user-friendly. This sentiment reveals a clear demand for security tools that are not only effective but that don\'t get in users\' way. Survey of IT and information security professionals The good news is that last year phishing attacks were down. In 2023, 71% of organizations experienced at least one successful phishing attack compared to 84% in 2022. The bad news is that the consequences of successful attacks were more severe. There was a 144% increase in reports of financial penalties. And there was a 50% increase in reports of damage to their reputation. Another major challenge was ransomware. The survey revealed that 69% of organizations were infected by ransomware (vs. 64% in 2022). However, the rate of ransom payments declined to 54% (vs. 64% in 2022). To address these issues, 46% of surveyed security pros are increasing user training to help change risky behaviors. This is their top strategy for improving cybersecurity. Threat landscape and security awareness data Business email compromise (BEC) is on the rise. And it is now spreading among non-English-speaking countries. On average, Proofpoint detected and blocked 66 million BEC attacks per month. Other threats are also increasing. Proofpoint observed over 1 million multifactor authentication (MFA) bypass attacks using EvilProxy per month. What\'s concerning is that 89% of surveyed security pros think MFA is a “silver bullet” that can protect them against account takeover. When it comes to telephone-oriented attack delivery (TOAD), Proofpoint saw 10 million incidents per month, on average. The peak was in August 2023, which saw 13 million incidents. When looking at industry failure rates for simulated phishing campaigns, the finance industry saw the most improvement. Last year the failure rate was only 9% (vs. 16% in 2022). “Resil | Ransomware Tool Vulnerability Threat Studies Technical | ★★★★ | |

\'Cyber insecurity\' is among the most pressing issues facing organizations globally in 2024, according to new research from the World Economic Forum (WEF). In its Global Cybersecurity Outlook 2024 report, the WEF found that more than eight in ten organizations surveyed feel more or as exposed to cyber crime than last year. How can businesses implement proficient cyber capabilities in an era where cyber threats from criminals and hacktivists are escalating in complexity and magnitude? This is crucial for adapting swiftly to the constantly evolving security challenges and confidently pursuing growth through digital innovation in products, services, and organizational transformation. In today\'s rapidly changing cyber threat environment, Chief Information Security Officers (CISOs) and security operations teams must adopt forward-thinking strategies. These strategies should focus on quickly identifying and addressing the most pressing vulnerabilities in their digital environments. Cyber attackers\' increasing sophistication and speed have prompted organizations of various sizes to re-evaluate their legacy systems, governance policies, and overall security stances, aiming to align with the latest industry standards The shift towards digital platforms and the widespread adoption of cloud technologies have expanded the avenues for cyber-attacks, consequently enlarging the attack surface. This growing attack surface includes vulnerable systems, compromised data, and unauthorized assets, highlighting the necessity for a consistent and ongoing security strategy. This strategy should be centered on managing and mitigating threats efficiently and accurately. Security leaders are becoming increasingly aware of the importance of such an approach.

2024-02-02 05:00:36 | Développement d'une nouvelle norme Internet: le cadre de la politique relationnelle du domaine Developing a New Internet Standard: the Domain Relationship Policy Framework (lien direct) |
Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. In this blog post, we discuss the Domain Relationship Policy Framework (DRPF)-an effort that has been years in the making at Proofpoint. The DRPF is a simple method that is used to identify verifiably authorized relationships between arbitrary domains. We create a flexible way to publish policies. These policies can also describe complex domain relationships. The details for this new model require in-depth community discussions. These conversations will help us collectively steer the DRPF toward becoming a fully interoperable standard. We are now in the early proposal stage for the DRPF, and we are starting to engage more with the broader community. This post provides a glimpse down the road leading to standardization for the DRPF. Why Proofpoint developed DRPF To shine a light on why Proofpoint was inspired to develop the DRPF in the first place, let\'s consider the thinking of the initial designers of the Domain Name System (DNS). They assumed that subdomains would inherit the administrative control of their parent domains. And by extension, this should apply to all subsequent subdomains down the line. At the time, this was reasonable to assume. Most early domains and their subdomains operated in much the same way. For example, “university.edu” directly operated and controlled the administrative policies for subdomains such as “lab.university.edu” which flowed down to “project.lab.university.edu.” Since the mid-1980s, when DNS was widely deployed, there has been a growing trend of delegating subdomains to third parties. This reflects a breakdown of the hierarchical model of cascading policies. To see how this works, imagine that a business uses “company.com” as a domain. That business might delegate “marketing.company.com” to a third-party marketing agency. The subdomain must inherit some policies, while the subdomain administrator may apply other policies that don\'t apply to the parent domain. Notably, there is no mechanism yet for a domain to declare a relationship with another seemingly independent domain. Consider a parent company that operates multiple distinct brands. The company with a single set of policies may want them applied not only to “company.com” (and all of its subdomains). It may also want them applied to its brand domains “brand.com” and “anotherbrand.com.” It gets even more complex when any of the brand domains delegate various subdomains to other third parties. So, say some of them are delegated to marketing or API support. Each will potentially be governed by a mix of administrative policies. In this context, “policies” refers to published guidance that is used when these subdomains interact with the domain. Policies might be for information only. Or they might provide details that are required to use services that the domain operates. Most policies will be static (or appear so to the retrieving parties). But it is possible to imagine that they could contain directives akin to smart contracts in distributed ledgers. 3 Design characteristics that define DRPF The goal of the DRPF is to make deployment and adoption easier while making it flexible for future use cases. In many prior proposals, complex requirements bogged down efforts to get rid of administrative boundaries between and across disparate domains. Our work should be immediately useful with minimal effort and be able to support a wide array of ever-expanding use cases. In its simplest form, three design characteristics define the DRPF: A domain administrator publishes a policy assertion record for the domain so that a relying party can discover and retrieve it. The discovered policy assertion directs the relying party to where they can find | Tool Prediction Cloud Technical | ★★★ | |

2024-01-30 11:00:00 | Darkgate Malware livré via Microsoft Teams - Détection et réponse DarkGate malware delivered via Microsoft Teams - detection and response (lien direct) |
Executive summary
While most end users are well-acquainted with the dangers of traditional phishing attacks, such as those delivered via email or other media, a large proportion are likely unaware that Microsoft Teams chats could be a phishing vector. Most Teams activity is intra-organizational, but Microsoft enables External Access by default, which allows members of one organization to add users outside the organization to their Teams chats. Perhaps predictably, this feature has provided malicious actors a new avenue by which to exploit untrained or unaware users.
In a recent example, an AT&T Cybersecurity Managed Detection and Response (MDR) customer proactively reached out with concerns about a user who was external to their domain sending an unsolicited Teams chat to several internal members. The chat was suspected to be a phishing lure. The customer provided the username of the external user as well as the IDs of multiple users who were confirmed to have accepted the message.
With this information, the AT&T Cybersecurity MDR SOC team was able to identify the targeted users, as well as suspicious file downloads initiated by some of them. A review of the tactics and indicators of compromise (IOCs) utilized by the attacker showed them to be associated with DarkGate malware, and the MDR SOC team was able to head off the attack before any significant damage was done.
Investigation
Initial event review
Indicators of compromise
The customer provided the below screenshot (Image 1) of the message that was received by one of their users and which was suspected to be a phishing lure. An important detail to note here is the “.onmicrosoft.com” domain name. This domain, by all appearances, is authentic and most users would probably assume that it is legitimate. OSINT research on the domain also shows no reports for suspicious activity, leading the MDR SOC team to believe the username (and possibly the entire domain) was likely compromised by the attackers prior to being used to launch the phishing attack.
Image 1: Screenshot from customer of received message
Expanded investigation
Events search
Performing a search of the external username in the customer’s environment led the MDR team to over 1,000 “MessageSent” Teams events that were generated by the user. Although these events did not include the IDs of the recipients, they did include the external user’s tenant ID, as displayed in Image 2 below.
Image 2: Event log showing external user tenant ID
A Microsoft 365 tenant ID is a globally unique identifier assigned to an organization. It is what allows members of different companies to communicate with one another via Teams. As long as both members of a chat have valid tenant IDs, and External Access is enabled, they can exchange messages. With this in mind, the MDR SOC team was able to query events that contained the external user’s tenant ID and found multiple “MemberAdded” events, which are generated when a user joins a chat in Teams.
Image 3: “MemberAdded” event
These events include the victim’s user ID, but not the external user ID. In addition to the external tenant ID, the MDR SOC team was able to positively link these “MemberAdded” events back to the attacker via the “ChatThreadId” field, which was also present in the original “MessageSent&rdq |

2024-01-22 06:00:26 | Types de menaces et d'attaques d'identité que vous devez être consciente Types of Identity Threats and Attacks You Should Be Aware Of (lien direct) |
It\'s easy to understand why today\'s cybercriminals are so focused on exploiting identities as a key step in their attacks. Once they have access to a user\'s valid credentials, they don\'t have to worry about finding creative ways to break into an environment. They are already in. Exploiting identities requires legwork and persistence to be successful. But in many ways this tactic is simpler than exploiting technical vulnerabilities. In the long run, a focus on turning valid identities into action can save bad actors a lot of time, energy and resources. Clearly, it\'s become a favored approach for many attackers. In the past year, 84% of companies experienced an identity-related security breach. To defend against identity-based attacks, we must understand how bad actors target the authentication and authorization mechanisms that companies use to manage and control access to their resources. In this blog post, we will describe several forms of identity-based attacks and methods and offer an overview of some security controls that can help keep identity attacks at bay. Types of identity-based attacks and methods Below are eight examples of identity attacks and related strategies. This is not an exhaustive list and, of course, cybercriminals are always evolving their techniques. But this list does provide a solid overview of the most common types of identity threats. 1. Credential stuffing Credential stuffing is a type of brute-force attack. Attackers add pairs of compromised usernames and passwords to botnets that automate the process of trying to use the credentials on many different websites at the same time. The goal is to identify account combinations that work and can be reused across multiple sites. Credential stuffing is a common identity attack technique, in particular for widely used web applications. When bad actors find a winning pair, they can steal from and disrupt many places at once. Unfortunately, this strategy is highly effective because users often use the same passwords across multiple websites. 2. Password spraying Another brute-force identity attack method is password spraying. A bad actor will use this approach to attempt to gain unauthorized access to user accounts by systematically trying commonly used passwords against many usernames. Password spraying isn\'t a traditional brute-force attack where an attacker attempts to use many passwords against a single account. It is a more subtle and stealthy approach that aims to avoid account lockouts. Here\'s how this identity attack usually unfolds: The attacker gathers a list of usernames through public information sources, leaked databases, reconnaissance activities, the dark web and other means. They then select a small set of commonly used or easily guessable passwords. Next, the attacker tries each of the selected passwords against a large number of user accounts until they find success. Password spraying is designed to fly under the radar of traditional security detection systems. These systems may not flag these identity-based attacks due to the low number of failed login attempts per user. Services that do not implement account lockout policies or have weak password policies are at risk for password spraying attacks. 3. Phishing Here\'s a classic and very effective tactic that\'s been around since the mid-1990s. Attackers use social engineering and phishing to target users through email, text messages, phone calls and other forms of communication. The aim of a phishing attack is to trick users into falling for the attacker\'s desired action. That can include providing system login credentials, revealing financial data, installing malware or sharing other sensitive data. Phishing attack methods have become more sophisticated over the years, but they still rely on social engineering to be effective. 4. Social engineering Social engineering is more of an ingredient in an identity attack.

Credential stuffing is a common identity attack technique, in particular for widely used web applications. When bad actors find a winning pair, they can steal from and disrupt many places at once. Unfortunately, this strategy is highly effective because users often use the same passwords across multiple websites. 2. Password spraying Another brute-force identity attack method is password spraying. A bad actor will use this approach to attempt to gain unauthorized access to user accounts by systematically trying commonly used passwords against many usernames. Password spraying isn\'t a traditional brute-force attack where an attacker attempts to use many passwords against a single account. It is a more subtle and stealthy approach that aims to avoid account lockouts. Here\'s how this identity attack usually unfolds: The attacker gathers a list of usernames through public information sources, leaked databases, reconnaissance activities, the dark web and other means. They then select a small set of commonly used or easily guessable passwords. Next, the attacker tries each of the selected passwords against a large number of user accounts until they find success. Password spraying is designed to fly under the radar of traditional security detection systems. These systems may not flag these identity-based attacks due to the low number of failed login attempts per user. Services that do not implement account lockout policies or have weak password policies are at risk for password spraying attacks. 3. Phishing Here\'s a classic and very effective tactic that\'s been around since the mid-1990s. Attackers use social engineering and phishing to target users through email, text messages, phone calls and other forms of communication. The aim of a phishing attack is to trick users into falling for the attacker\'s desired action. That can include providing system login credentials, revealing financial data, installing malware or sharing other sensitive data. Phishing attack methods have become more sophisticated over the years, but they still rely on social engineering to be effective. 4. Social engineering Social engineering is more of an ingredient in an identity attack. It\'s all about the deception and manipulation of users, and it\'s a feature in | Technical | ★★ | |

2024-01-17 06:00:02 | Comment mettre en place un programme de gestion des menaces d'initié et de prévention des pertes de données How to Set Up an Insider Threat Management and Data Loss Prevention Program (lien direct) |
This blog post is adapted from our e-book, Getting Started with DLP and ITM. The last few years have brought unprecedented change. An increasingly distributed workforce, access to more data through more channels and a shift to the cloud have transformed the nature of work. These trends have made protecting sensitive data more complicated and demanding. What\'s clear is that organizations are struggling to rise to the challenge. Between 2020 and 2022, insider threats increased by a staggering 44%. And the costs of addressing them increased 34%-from $11.45 million to $15.38 million. This upswing mainly comes down to two factors. For starters, most security teams have little visibility into people-caused data loss and insider-led security incidents. And few have the tools or resources to handle it. That\'s why Gartner sees platforms for data loss prevention and insider threat management (DLP and ITM) increasingly converging. Businesses need tools and processes that give them holistic, contextualized insights that take user behavior into account. It\'s no longer enough to focus on data-and where it\'s moving. To prevent data loss, industry leaders need to take a people-centric approach that expands beyond traditional drivers like compliance. In this blog post, we\'ll explore some basics for designing an ITM and DLP program. This can help you approach information protection in a way that\'s built for how modern organizations work. Why information protection is so challenging Risks are everywhere in today\'s complex landscape. Here are a few changes making it difficult for companies to protect their data. More data is open to exposure and theft. As businesses go digital, more data is being generated than ever before. According to IDC\'s Worldwide Global DataSphere Forecast, the total amount of data generated data will double from 2022 to 2026. That means malicious insiders will have more access to more sensitive data through more channels. It will also be easier for careless users to expose data inadvertently. Plus, any security gap between channels, any misconfiguration or any accidental sharing of files can give external attackers more opportunities to steal data. New data types are hard to detect. Data isn\'t just growing in volume. It\'s also becoming more diverse, which makes it harder to detect and control. With traditional DLP program tools, data typically fits within very tightly defined data patterns (such as payment card number). But even then, it generates too many false positives. Now, key business data is more diverse and can be graphical, tabular or even source code. The network security perimeter no longer exists. With more employees and contractors working remotely, the security perimeter has shifted from brick and mortar to one based on people. Add to the mix bring-your-own-device (BYOD) practices, where the personal and professional tend to get blurred, and security teams have even more risks to contend with. In a survey for the 2023 State of the Phish report from Proofpoint, 72% of respondents said they use one or more of their personal devices for work. Employee churn is high. Tech industry layoffs in 2022 and 2023 have seen many employees leaving and joining businesses at a rapid rate. The result is greater risk of data exfiltration, infiltration and sabotage. Security leaders know it, too-39% of chief information security officers rated improving information protection as the top priority over the next two years. Security talent is in short supply. A lack of talent has left many security teams under-resourced. And the situation is likely to get worse. In 2023, the cybersecurity workforce gap hit an all-time high-there are 4 million more jobs than there are skilled workers. DLP vs. ITM What\'s the difference between DLP and ITM? Both DLP and ITM work to prevent data loss. But they achieve it in different ways.

This is part one of a three-part series written by AT&T Cybersecurity evangelist Theresa Lanowitz. It’s intended to be future-looking and provocative and to encourage discussion. The author wants to assure you that no generative AI was used in any part of this blog. Entering 2024 brings us well into the third decade of the new millennium. Do you recall how tentatively and maybe naively we approached the year 2000, otherwise known as Y2K? We stressed over two bytes in COBOL programs and regression tested every line of code to ensure our systems were ready to go at midnight on January 1, 2000. The clock struck 12, and the world breathed a collective sigh of relief – we survived the predicted digital disaster. And just like that, off we went - to create web, mobile, and cloud apps, to turn embedded software into the Internet of Things (IoT), and to democratize computing in a way that was only a dream just 23 years ago. With massive shifts and changes in computing in the wake, it’s time to ask: where are we going in 2024, and what cybersecurity opportunities and challenges lie ahead? Maturing the industry: It’s the business that matters. Cybersecurity is not about fear, uncertainty, and doubt (FUD). It is about delivering business outcomes such as boarding a plane quicker to mitigate flight delay penalties, heating or cooling my house efficiently to manage energy consumption in various climates, or reducing waste in manufacturing to minimize product recalls. Notice there was no mention of security, data, network, coding, or anything remotely IT-centric or technical in the stated business outcomes above. We must aspire to this when thinking about our businesses and cybersecurity. It must be about the business first, advancing the customer experience, and removing friction. Cybersecurity is now a business requirement. For cybersecurity to be part of business planning, cybersecurity teams need to become members of the business teams. Over the past three years, the cybersecurity market has rapidly matured. We are in the midst of market consolidation, with individual point products being acquired and integrated into platform offerings. These platform offerings will continue to evolve by acquiring smaller vendors, partnering, and innovating. The platform vendors clearly see the need for cybersecurity to be a part of the business conversation and want to act as a business partner and trusted advisor, not merely a product provider. Cybersecurity budgets are changing, creating an approach to get funding differently. This year, our research revealed an unexpected change: money is being redistributed as computing moves closer to the data source. Our respondents reported they are investing in new computing development – in this case, edge computing - in a way that’s different from what we’ve seen in the past. They are proactively investing in strategy and planning, the network, application development, and security to create a balanced, collaborative ecosystem. The big surprise isn’t a new secret weapon or killer application. The surprise is what’s needed: a new way of thinking about resource allocation. You’ll still need your usual hardware, software, storage, and security buckets. How you balance those expenses is what’s different. As computing moves closer to the data source, every deployment should contribute to the b | Tool Mobile Prediction Cloud Technical | ★★★ |
