Abid Khan, Global Head—Cyber Security Services Of HGS, On Evolving Cyber Threat Landscape

Abid Khan: “The increasing prevalence of AI presents a double-edged sword for cybersecurity. While AI offers powerful tools for enhancing security, it also introduces a new class of vulnerabilities that must be addressed. On the positive side, AI can significantly improve threat detection by analyzing massive datasets to identify subtle patterns and anomalies that would be impossible for human analysts to spot. This leads to faster and more accurate threat identification. Furthermore, AI can automate responses to common attacks, freeing up security professionals to focus on more complex and sophisticated threats. AI's ability to analyze historical data and current trends also enables predictive security, allowing organizations to proactively strengthen their defenses against potential attacks.

“However, the rise of AI has also created new avenues for malicious actors. AI-powered attacks are becoming increasingly sophisticated and targeted. These types of attacks include data poisoning, where attackers manipulate training data to make AI systems unreliable; model inversion, which allows the theft of sensitive information by reverse-engineering AI models; and adversarial attacks, where carefully crafted inputs can fool AI systems, as seen in the example of manipulated images confusing self-driving cars. Beyond these, the theft and replication of AI models for malicious purposes, such as creating counterfeit products or launching targeted attacks, pose a significant threat. Finally, the inherent ‘black box’ nature of some AI models can create security vulnerabilities, as the lack of transparency in their decision-making processes can make it difficult to identify and mitigate potential weaknesses.”

Abid Khan: “AI in cybersecurity is shifting from a reactive defense approach to a proactive, predictive strategy. Currently, AI primarily functions as a sophisticated detection and response system, analyzing data, identifying anomalies, and automating responses to known threats. While valuable, this is fundamentally reactive. The future of AI in cybersecurity lies in anticipating and preventing attacks before they occur. This transition is crucial because threat actors are also leveraging AI, creating more sophisticated and evasive attacks. Therefore, remaining ahead of the curve demands AI systems capable of not just reacting but also anticipating and pre-empting these AI-driven threats—a true AI arms race.

“Several key developments are driving this proactive shift. AI-powered predictive threat intelligence analyses vast amounts of threat data to forecast potential attacks, enabling proactive patching and defense strengthening. What’s more, AI-driven threat hunting proactively searches for hidden threats within networks, uncovering subtle anomalies before they escalate. Adaptive security postures, enabled by AI, dynamically adjust security configurations based on real-time threat assessments and predicted scenarios. Sophisticated deception technologies, also powered by AI, create realistic decoys to lure attackers, providing valuable insights into their tactics, techniques, and procedures (TTP). Finally, AI-driven vulnerability management prioritizes patching based on exploitation likelihood and potential impact, optimizing resource allocation.

“This move to proactive security is not merely advantageous; it's essential. As cybercriminals increasingly utilize AI for more sophisticated, targeted, and automated attacks, traditional reactive defenses become insufficient. Only AI systems capable of anticipating and pre-empting these AI-driven attacks can effectively safeguard organizations. The cybersecurity landscape is evolving into an AI-driven battleground, demanding continuous innovation and adaptation to maintain a proactive security posture.”

Abid Khan:  “Enterprise cybersecurity programs must evolve beyond simply reacting to known threats like ransomware and distributed denial-of-service (DDoS) attacks. A robust strategy requires a multilayered approach that combines foundational security hygiene, advanced threat detection, and continuous adaptation. This starts with basic but crucial elements like strong access controls, regular vulnerability patching, and comprehensive security awareness training for all employees. These fundamentals create a strong base upon which more sophisticated measures can be established.

“Building upon this foundation, organizations need to implement advanced threat detection and mitigation capabilities. This includes network security monitoring, security information and event management (SIEM) systems for log analysis, and deception technologies to lure attackers and gain insights into their tactics. Threat intelligence feeds are also vital, providing up-to-date information on the latest threats and vulnerabilities. Critically, AI and machine learning play an increasingly important role, enabling anomaly detection, predictive threat modelling, and automated incident response, significantly enhancing the speed and accuracy of threat identification and mitigation.

“To truly adapt to the ever-evolving threat landscape, especially the emergence of zero-day exploits, a proactive security posture is essential. This involves leveraging AI for behavioral analysis and sandboxing suspicious files to identify unknown threats. The Zero Trust security model, which assumes no implicit trust and requires verification for every user and device, further limits the impact of successful breaches. Automating security tasks and securing cloud environments are also crucial components of a modern security strategy.

“Finally, a well-defined incident response plan, alongside robust data backup and recovery procedures, is indispensable. Regularly testing and updating the incident response plan ensures that organizations are prepared to handle any attack, including those involving zero-day exploits. Coupled with continuous improvement through threat hunting, security audits, and staying informed about the latest threats, these measures enable organizations to not only detect and mitigate current threats but also proactively adapt to the unknown challenges of tomorrow's cyber landscape.”

Abid Khan: “The increasing sophistication and global reach of cyber threats make cross-industry and cross-border collaboration absolutely essential for building a more resilient digital ecosystem.  Cyberattacks often transcend geographical boundaries and target multiple sectors simultaneously, exploiting interconnected systems and supply chains. No single organization or nation can effectively combat these threats in isolation.  Sharing threat intelligence, best practices, and incident response strategies across industries and borders allows for a more comprehensive and coordinated defense.  This collaborative approach enables organizations to learn from each other's experiences, identify emerging threats faster, and develop more effective countermeasures.  Without such collaboration, cybercriminals can exploit vulnerabilities in one sector or country to gain access to others, creating a cascading effect with potentially devastating consequences.   

“Law enforcement agencies play a crucial role in investigating and prosecuting cybercriminals, disrupting their operations, and deterring future attacks. International cooperation between law enforcement agencies is particularly important given the transnational nature of cybercrime.  Sharing information, coordinating investigations, and extraditing cybercriminals across borders are essential steps in bringing perpetrators to justice.  Furthermore, law enforcement can work with private sector organizations to provide technical assistance, share threat intelligence, and help them improve their security posture. This collaboration can be facilitated through joint task forces, information sharing platforms, and public-private partnerships.   

“Regulators also have a significant role to play in fostering cybersecurity resilience. They can establish cybersecurity standards and regulations that organizations must adhere to, ensuring a baseline level of security across industries. These regulations can address areas such as data protection, incident reporting, and security risk management. Regulators can also promote information sharing and collaboration between organizations, as well as encourage the adoption of best practices.  Furthermore, they can work with international organizations to develop harmonized cybersecurity standards and regulations, facilitating cross-border cooperation and reducing regulatory fragmentation.   

“Private entities, including businesses, cybersecurity firms, and technology providers, are at the forefront of the fight against cyber threats.  They possess valuable threat intelligence, technical expertise, and incident response capabilities. By actively participating in information sharing initiatives, collaborating with law enforcement and regulators, and investing in their own cybersecurity defenses, private entities contribute significantly to the overall resilience of the digital ecosystem.

“Sharing anonymized threat data, developing innovative security solutions, and promoting cybersecurity awareness are just some of the ways private entities can contribute.  Ultimately, a collective effort involving all stakeholders—law enforcement, regulators, and private entities—is essential to effectively address the growing cyber threat landscape and build a more secure and resilient digital future.”   

Abid Khan:  “I agree that AI is poised to be the most impactful trend in cybersecurity, and the point about data is key. Cybersecurity professionals rely heavily on understanding organizational and individual habits related to data interaction and creation. The challenge has always been the need for more data to accurately distinguish between normal and abnormal activity. Take a credit card, for example. Given the vast swathes of purchasing data available nowadays, if the card is stolen and used to make purchases, the fraudulent activity stands out more clearly.

“AI addresses this challenge by exponentially increasing the amount of usable data. It's not just that AI generates data, but it analyzes and interprets data at a scale and speed previously unimaginable. This allows organizations to develop a much richer and more nuanced understanding of “normal behavior.” By processing vast quantities of information, AI can identify subtle patterns and anomalies that humans are unable to detect. This enhanced visibility makes abnormal activity, indicative of a potential cyber threat, stand out much more sharply and quickly. In essence, AI supercharges our ability to discern the signal from the noise, dramatically improving threat detection and response.”

Abid Khan:  “You're right, existing compliance frameworks like COBIT, GDPR, HIPAA, and NIST standards have provided valuable guidance. The EU AI Act and AI MMS are excellent examples of how legislation can address emerging technologies like AI, setting ethical guidelines and data usage standards. Adhering to these regulations does indeed help organizations build robust internal data management structures, mitigating risks like bias and creating a foundation for future compliance. However, as you pointed out, these regulations, while useful, now need to evolve to address the rapidly changing landscape, particularly the proliferation of AI and its associated security risks.

“The next stage of compliance must focus on establishing concrete guardrails around AI. This means moving beyond general ethical guidelines and data usage principles to address the specific security challenges posed by AI itself. Organizations should proactively consider how to protect their AI systems from cyber threats. This includes addressing vulnerabilities to data poisoning, model inversion attacks, and adversarial attacks, among others. Protecting AI models and the data they rely on will likely be a central focus of the next wave of legislation. Therefore, organizations that begin addressing these AI-specific security concerns now will be well-positioned to adapt to future regulatory requirements and maintain a strong security posture. This proactive approach, rather than simply reacting to new regulations, is key to streamlining compliance strategies and ensuring continuous adherence in the evolving world of AI-driven cybersecurity.”
