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.

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 | |

2020-12-15 11:00:00 | Why application-layer encryption is essential for securing confidential data (lien direct) | This blog was written by an independent guest blogger. Your business is growing at a steady rate, and you have big plans for the future. Then, your organization gets hit by a cyberattack, causing a massive data breach. Suddenly, your company’s focus is shifted to sending out letters to angry customers informing them of the incident - which is required by law in most states - and devising strategies to deal with the backlash. This is an all too common scenario for many businesses, and the unfortunate truth is that most organizations fail to adopt the correct cybersecurity procedures until after an attack. The good news is that with a proactive approach to protecting your data, these kinds of nightmares can be avoided. New technology is constantly providing hackers new opportunities to commit cybercrimes. Most organizations have encrypted their data whether it’s stored on the cloud or in a server provided by their web host, but this isn’t enough. Even properly encrypted disc level encryption is vulnerable to security breaches. In this article, we will discuss the weaknesses found in disc level encryption and why it’s best to ensure your data is encrypted at the application layer. We’ll also discuss the importance of active involvement from a cybersecurity team in the beginning stages of application development, and why developers need to have a renewed focus on cybersecurity in a “security-as-code” culture. The importance of application-layer security Organizations all too often have a piecemeal, siloed approach to security. Increasingly competitive tech environments have pushed developers into building new products at a pace cybersecurity experts sometimes can’t keep up with. This is why it’s becoming more common for vulnerabilities to be detected only after an application launches or a data breach occurs. Application layer encryption reduces surface area and encrypts data at the application level. That means if one application is compromised, the entire system does not become at risk. To reduce attack surfaces, individual users and third parties should not have access to encrypted data or keys. This leaves would-be cybercriminals with only the customer-facing end of the application for finding vulnerabilities, and this can be easily protected and audited for security. Building AI and application-layer security into code Application layer security and building security into the coding itself requires that your DevOps and cybersecurity experts work closely together to form a DevSecOps dream team. Developers are increasingly working hand-in-hand with cybersecurity experts from the very beginning stages of software development to ensure a “security-as-code” culture is upheld. However, there are some very interesting developments in AI that present opportunities to streamline this process. In fact, 78% of data scientists agree that artificial intelligence will have the greatest impact on data protection for the decade. Here are four ways AI is transforming application layer security: 1. Misuse detection or application security breach detection Also referred to as signature-based detection, AI systems alert teams when familiar attack patterns are noticed. | Data Breach Vulnerability Threat | Deloitte | |

2020-06-15 11:00:00 | Cybersecurity in education: Securing schools as they transition to online learning (lien direct) | This blog was written by an independent guest blogger. Whether they were prepared for it or not, schools around the world have been forced to adopt an online learning model for students thanks to the COVID-19 pandemic. One of the biggest concerns educators need to have in this situation is exactly how to create a fully secure remote learning environment in order to keep sensitive information for both the schools and individual students safe from hackers. Data breaches cause real-world damage and tarnish the credibility of the organizations that fall prey to them (including schools and educational institutions). As schools across the globe turn digital due to students studying from home, they are also becoming more vulnerable targets to cyberattacks. Schools are finding themselves outmatched as these threats intensify. Parents likewise need to learn about and ensure safe cybersecurity practices for their kids, and would therefore also benefit from learning about the security methods that we are about to cover. In this article, we’ll discuss how school technology leaders can develop the necessary strategies to protect against and mitigate breaches by procuring technology and developing risk management policies and planning for incidents before they occur. Why Are Schools At Risk of Cyber Attacks? In the face of the COVID-19 pandemic, the focus and attention of most of the cybersecurity community have been on protecting government institutions, the airline industry, and the healthcare industry from hackers. This is good, but educational institutions are at just as much risk from malicious hackers as the above industries and organizations are as well. If anything, this risk has only increased significantly due to the record numbers of students who are now attending school via online learning platforms, video conferences, and e-learning environments. In the United States, the Federal Bureau of Investigation has warned extensively about the greatly increased cybersecurity risks of teleconferencing and online classrooms. The FBI specifically cites examples of malicious cybercriminals delivering threatening content to Zoom classroom calls (colloquially referred to as Zoom-bombing), which has even resulted in numerous school districts pulling out of Zoom and seeking alternative platforms. This highlights a larger issue of schools and school districts using technology that has either not been properly vetted or that educators and students are not prepared to use safely. In other words, even as school districts turn to alternative teleconferencing options besides Zoom, they can still be a major risk of falling prey to hackers and cybercriminals. This leads us to our next question: what exactly can school districts and educational inst | Malware Vulnerability Guideline | Deloitte | |
