The genius at the heart of AI—its ability to sift through mountains of data, actually spot a needle in a haystack, and act on threats before they blossom into full-scale emergencies—it’s undeniable. However, here’s the rub—every part of that impressive arsenal? It’s also up for grabs by the other side, and can (and will) arm them to launch attacks of unprecedented sophistication and elusiveness, the likes of which we’ve thankfully never seen up to now. How do we wield this impressive technology to fortify our defenses, while preventing it from falling into the wrong hands? Can such a thing even be accomplished? Join me below as we take a closer look at how AI’s rapid rise is changing the landscape of cybersecurity. AI as a Defense Tool AI is a reliable navigator for charting the digital deluge—it has the ability to handle vast quantities of information rapidly on a level that no human could ever hope to match. It doesn’t take a huge leap to come to the conclusion that those capabilities can very easily be leveraged for defense. Automated Threat Detection Think of AI as the ever-watchful eye, tirelessly scanning the horizon for signs of trouble in the vast sea of data. Its capability to detect threats with speed and precision beyond human ken is our first line of defense against the shadows that lurk in the network traffic, camouflaged in ordinary user behavior, or embedded within the seemingly benign activities of countless applications. AI isn’t just about spotting trouble; it’s about understanding it. Through machine learning, it constructs models that learn from the DNA of malware, enabling it to recognize new variants that bear the hallmarks of known threats. This is akin to recognizing an enemy’s tactics, even if their strategy evolves. All of what I’ve said also here applies to incident response—with AI’s ability to automatically meet threats head-on making a holistic cybersecurity posture both easier to achieve and less resource-intensive for organizations of all sizes. Predictive Analytics By understanding the patterns and techniques used in previous breaches, AI models can predict where and how cybercriminals might strike next. This foresight enables organizations to reinforce their defenses before an attack occurs, transforming cybersecurity from a reactive discipline into a proactive strategy that helps prevent breaches rather than merely responding to them. The sophistication of predictive analytics lies in its use of diverse data sources, including threat intelligence feeds, anomaly detection reports, and global cybersecurity trends. This comprehensive view allows AI systems to identify correlations and causations that might elude human analysts. Phishing Detection and Email Filtering AI has stepped up as a pivotal ally in the ongoing skirmish against phishing and other forms of social engineering attacks, which too often lay the groundwork for more invasive security breaches.

Integrating IT and OT security for a comprehensive approach to cyber threats in the digital age. Historically, IT and OT have operated in separate worlds, each with distinct goals and protocols. IT, shaped by the digital age, has always emphasized the protection of data integrity and confidentiality. In this space, a data breach can lead to significant consequences, making it crucial to strengthen digital defenses. On the other hand, OT, a legacy of the Industrial Revolution, is all about ensuring machinery and processes run without interruptions. Any machine downtime can result in major production losses, making system availability and safety a top priority. This difference in focus has created a noticeable cultural gap. IT teams, often deep into data management, might not fully grasp the real-world impact of a stopped production line. Similarly, OT teams, closely connected to their machines, might not see the broader impact of a data breach. The technical challenges are just as significant. OT systems are made up of specialized equipment, many from a time before cybersecurity became a priority. When these older systems connect to modern IT networks, they can become weak points, open to today\'s cyber threats. This risk is even higher because many OT systems use unique protocols and hardware. These systems, once isolated, are now part of more extensive networks, making them accessible and vulnerable through different points in an organization\'s network. Additionally, common IT tasks, like updating software, can be more complex in OT. The equipment in OT often has specific requirements from their manufacturers. What\'s standard in IT can become a complicated task in OT because of the particular nature of its systems. Combining IT and OT is more than just a technical task; it\'s a significant change in how companies see and manage risks. From the physical risks during the Industrial Revolution, we\'ve moved to a time when online threats can have real-world effects. As companies become part of bigger digital networks and supply chains, the risks increase. The real challenge is how to unify IT and OT security strategies to manage cyber risks effectively. The imperative of unified security strategies According to a Deloitte study, a staggering 97% of organizations attribute many of their security challenges to their IT/OT convergence efforts. This suggests that the convergence of IT and OT presents significant challenges, highlighting the need for more effective security strategies that integrate both domains. Steps to integrate IT and OT security: Acknowledge the divide: The historical trajectories of IT and OT have been distinct. IT has emerged as a standardized facilitator of business processes, while OT has steadfastly managed tangible assets like production mechanisms and HVAC systems. Therefore, the first step towards a unified front is recognizing these inherent differences and fostering dialogues that bridge the understanding gap between IT and OT teams and leaders. Develop a unified security framework: Optimized architecture: Given the distinct design principles of OT, which traditionally prioritized isolated operations, it\'s crucial to devise an architecture that inherently safeguards each component. By doing so, any vulnerability in one part of the system won\'t jeopardize the overall network\'s stability and security. Regular vulnerability assessments: Both environments should be subjected to periodic assessments to identify and address potential weak links.

2023-02-21 11:00:00 | 7 reasons why Endpoint Security and Response shouldn\'t be ignored (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. When strategizing a security approach for the coming year, many solutions will cross a CISO’s desk, all useful in covering some part of the network. Organizations must scrutinize every layer and each solution to make sure their security stack runs efficiently while still boasting a Defense-in-Depth approach. There cannot be an overload of alerts, the learning curve must be worth the cost, and all solutions must integrate with each other. Not surprisingly, the search can be tedious, complex, and confusing. Broadly speaking, cybersecurity defends the network and the devices on that network. Both are key and must be protected. Endpoint security and response includes “not only the automated monitoring and detection of threats on the endpoint, but also a combination of autonomous and manual investigation, remediation, and response.” While not every tool will make the cut, here are seven reasons why Endpoint Detection and Response (EDR) should not be ignored. Cybercriminals aren’t ignoring endpoints. It’s not surprising that in a recent study, 76% of IT decision-makers reported their company use of endpoint devices has gone up. This can include workstations, servers, tablets, smartphones and a host of IoT devices like cameras, smart speakers, and lighting. However, it is equally unsurprising that bad actors have capitalized on this gain, and consequently, 79% of IT teams have seen a rise in endpoint-related security breaches. The cyber talent crisis creates the need for autonomous response on the endpoint. With an increase of both endpoints and endpoint-related attacks, a proportional increase in endpoint security measures is needed; unfortunately, the ongoing cyber talent deficit hamstrings those efforts and makes whatever qualified cybersecurity experts are available difficult to attain for many small to medium-sized businesses. Endpoint security solutions use automatic investigation and monitoring techniques to spot threat 24/7/365 and often respond autonomously to mitigate them. This cuts back significantly on the work remaining for already-strapped security teams to do. EDR offers cloud-based security for end-user devices. One of the primary security problems facing fast-expanding, digitally native, and mid-transition companies is how to secure both on-premises and cloud-based assets. Endpoints, while not in the cloud, connect to it and bad actors can use vulnerabilities in device software to pivot to the rest of your network. State of the industry endpoint security platforms can deploy patches and run reboots from the cloud and offer enterprise-wide centralized cloud management. Remote device security trends downward as workers mix personal with professional. The rise of BYOD has been significant and ubiquitous in the wake of the remote-work migration, and a study by Gartner revealed that over 50% of workers used their own laptop or smartphone for work activity. Interestingly, a Ponemon study indicated that 67% of respondents reported that personal mobile devices have negatively impacted their company’s security posture, and 55% cite smartphones as | Tool Threat | Deloitte | ★★ |

2022-11-10 11:00:00 | The pros and cons of the digital transformation in banking (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. Digital transformation in banking began following the creation of the internet in the 1990s as a way for banks to deliver services to their customers more conveniently. Today, it has completely changed how most people interact with their banks. From opening a new account to making transactions and applying for loans, you can access all banking services directly from your computer or smartphone. According to an FDIC survey on banking behavior, over 80% of account holders engage in some form of digital banking. The popularity of digital banking stems from the convenience and level of personalization that it offers. But is digital banking good for you, or do the risks, such as cybersecurity issues, outweigh the benefits? Below, let’s explore some of the pros and cons of digital transformation in banking. Pros of digital transformation in banking Digital banking offers several advantages to the modern banking customer. Here are a few: 24/7 Access to your bank One of the most significant benefits of digital banking is that it gives you round-the-clock access to your account. You don’t have to wait for working hours to deposit your funds, get an account statement, change your account details, or transact funds. You can do it at any time from wherever you are. Additionally, you don’t have to waste time in long queues in the banking hall. Digital banking is like having your personal bank right in your pocket. Better rates, lower fees Banks typically charge account maintenance and transaction fees to cover expenses like employees, bank premises, etc. Since digital banking allows customers to serve themselves directly over the internet, there’s less demand for bank employees and multiple brick-and-mortar branches. Therefore, banks embracing digital transformation have lower overheads and can offer their customers lower fees and higher interest rates. These benefits are especially pronounced for purely digital banks without physical premises. Better customer experience A 2021 survey by Deloitte Insights found that digital-first banks routinely outperform traditional banks in multiple areas that matter most to customers, including simplicity of transactions, transaction speed, and the overall quality of the banking experience. Digital banks provide a smoother experience compared to traditional banks. For instance, transacting on a digital bank takes just a few minutes on your smartphone or laptop. In contrast, simply making a transaction in a traditional bank could take close to an hour as you must get to the physical bank, wait in line, fill out transaction forms, and speak to a teller. In addition, digital banks offer features like budgeting tools that make it easier to manage your money. They also update you on every aspect of your account with text and email alerts, such as when you make transactions, when you don’t have enough money for an upcoming bill, and so on. This makes the digital banking experience much better than what you get with a traditional bank. Automated payments With digital banks, it’s amazingly easy to automate your payments. You can set up payments that you want to make from your account every month, s | Ransomware Malware Tool | Deloitte Deloitte | |

2021-06-03 10:00:00 | (Déjà vu) Ransomware and Energy and Utilities (lien direct) | This is a blog series focused on providing energy and utility industries with helpful insights and practical, helpful information on cybersecurity. Intro The exponential growth of IoT devices in the energy and utilities industry has greatly increased focus on cybersecurity. Focus on cybersecurity across industries has increased recently, no doubt due to factors like COVID-19 forcing a jump in remote work. In 2020, we saw cybersecurity move from being a technical problem to a business issue. Along with the recognition that businesses really need to lead with a security-first mindset to be resilient, the CISO was elevated to a seat at the proverbial table as a true C-suite leader and trusted board advisor. Energy and utilities face unique challenges compared to other industries. According to McKinsey: “In our experience working with utility companies, we have observed three characteristics that make the sector especially vulnerable to contemporary cyberthreats. First is an increased number of threats and actors targeting utilities: nation-state actors seeking to cause security and economic dislocation, cybercriminals who understand the economic value represented by this sector, and hacktivists out to publicly register their opposition to utilities’ projects or broad agendas. The second vulnerability is utilities’ expansive and increasing attack surface, arising from their geographic and organizational complexity, including the decentralized nature of many organizations’ cybersecurity leadership. Finally the electric-power and gas sector’s unique interdependencies between physical and cyber infrastructure make companies vulnerable to exploitation, including billing fraud with wireless “smart meters,” the commandeering of operational-technology (OT) systems to stop multiple wind turbines, and even physical destruction.” Let’s look at one type of common and profitable attack that could impact energy and utility companies – ransomware. What is ransomware? Ransomware is exactly as the name implies – something valuable to your business is being kept from you until a ransom is paid for its return. In simple terms, ransomware is extortion. Ransomware, a form of malicious software, blocks you from accessing your computer systems or files until you pay the cyber adversary to allow you access to your information. The ransom is typically requested in crypto currency because of its anonymity and ease of online payment – this translates to no tracing of the origin or destination of the funds, a common tactic of cyber criminals. Knowingly infecting a system with ransomware and requesting payment to unlock the system is a crime. Law enforcement agencies recommend not paying the ransom associated with ransomware. The thought is that if the ransom is paid, you as the victim of ransomware are then identified as an easy target for further cybercrime and the ransomware attack is perpetuated against others. Who is the target of ransomware? Cyber criminals seek the path of least resistance in their targets and strike against businesses that are easy targets. Ransomware is a business and the perpetrators, like any good businessperson, are looking for a strong ROI. The C | Ransomware Malware Tool Vulnerability Guideline | Deloitte | |
