Authenticity centers on the authentication of an entity’s identity, whether it be a user, system, or device. With the proliferation of phishing and spear-phishing stratagems, ensuring authenticity has grown increasingly onerous. AI can proffer remedies such as biometric authentication, thereby ensuring that only duly authorized entities can access systems.
IoT (Internet of Things)
The Internet of Things (IoT) constitutes another pivotal notion, as the proliferation of interconnected devices broadens the scope of susceptibilities. AI can facilitate the guardianship of these devices by scrutinizing anomalous behaviors and implementing adaptive security measures.
These foundational notions serve as the bedrock upon which cybersecurity strategies are erected. A profound comprehension of these tenets is non-negotiable for any endeavor seeking to employ AI as a conduit to enhance Cybersecurity.
The ECSO Taxonomy
The European Cyber Security Organisation (ECSO) has devised a taxonomy that serves as a paradigm for comprehending the diverse stages of a cyber onslaught and how Artificial Intelligence (AI) solutions can be enlisted at each juncture. In accordance with the document, the stages can be delineated as follows:
Identify
This phase encompasses the organizational and strategic fortification of the cybersecurity IT infrastructure to manage risks. AI can exert a pivotal influence here by dissecting data patterns to discern potential vulnerabilities before they are susceptible to exploitation.
Protect
This juncture revolves around formulating and implementing measures to shield IT infrastructure against cyber perils. AI can aid in the automation of defenses and the acclimatization to novel forms of attacks.
Detect
This stage is devoted to identifying cybersecurity incidents. AI can enhance efficiency in threat detection by methodically analyzing prodigious data volumes in real-time.
Respond
This pertains to the formulation and execution of measures to respond judiciously to ascertained cybersecurity incidents. Here, AI can contribute to forensic analysis and the management of incidents.
Recover
This phase entails the development and implementation of solutions geared towards sustaining strategies, processes, and resources for the resilience of an organization’s IT systems and for reinstating impaired functionalities stemming from a cyber incident. AI can expedite the swift and efficient recuperation of affected systems.
The ECSO taxonomy extends its applicability across diverse business sectors, with an acute focus on 15 pivotal domains as defined by the European NIS 2 Directive concerning network and information systems security.
Significantly, the ECSO taxonomy not only serves as a theoretical archetype but also fashions a market radar that delineates the relevant domains or actions within the cybersecurity and AI milieu.
Adaptability of Cyber Attackers
The adaptability of cyber attackers has reached unprecedented levels, especially with the incorporation of Artificial Intelligence (AI) into their strategies. This phenomenon has become more evident in recent years due to several factors, including technological advances and changes in the social context, such as pandemic and geopolitical conflicts.
