Artificial intelligence: the definition
Artificial intelligence (AI) is a set of techniques and methods that enable machines to learn, reason and solve problems in a manner similar to human intelligence. There is as much excitement as there is fear about this rapidly evolving field. In the field of cybersecurity, AI is often seen as a valuable aid in countering threats. However, it can also be used maliciously by individuals or organisations seeking to compromise the security of IT systems.
In this article we will explore the different facets of AI applied to cyber security, looking at both the benefits and the potential risks, while incorporating concrete examples, technological advances, regulatory issues, transparency issues and future prospects.
1- The benefits of artificial intelligence in cybersecurity
One of the main advantages of AI in cybersecurity is its ability to detect threats quickly and efficiently. Using machine learning algorithms, security systems can identify anomalies in data flows, recognise suspicious digital signatures and anticipate malicious behaviour. For example, companies like Darktrace use AI to analyse network behaviour and detect threats in real time. In addition, AI can analyse risks and assess vulnerabilities in IT systems, enabling them to be better protected.
AI also plays a crucial role in incident response and crisis management. Incident response processes can be automated, allowing for faster real-time decision-making and coordination of actions. AI can also be used to simulate attacks and test the resilience of systems to threats, as shown by the increasing use of AI-assisted cyber-ranges.
Finally, artificial intelligence contributes to cybersecurity education and awareness among users. AI-assisted education and training programmes help to identify and prevent human error, while strengthening the security culture within organisations. Tools such as the CybSafe chatbot use AI to tailor training to specific employee needs.
2- The risks associated with the use of artificial intelligence in cybersecurity
Unfortunately, AI can also be used for malicious purposes by cybercriminals. They can automate their attacks and exploit system vulnerabilities more effectively. For example, attackers have used AI to create malware that can adapt to their environment and evade detection. In addition, advanced encryption algorithms can be used to hide malicious activity, making it even more difficult to detect.
Deepfakes and information manipulation are another AI-related danger. By generating fake images, videos or audio recordings, cybercriminals can deceive users and cause considerable harm. For example, deepfakes can be used to imitate the voice of a CEO and trick an employee into making a fraudulent transfer (a hypothetical situation based on the capabilities of text-to-speech and AI technologies).
AI also has limitations that can affect cybersecurity. Over-reliance on automated systems can lead to security breaches if they are compromised. In addition, AI algorithms can be subject to bias and misclassification, which can lead to false alarms or missed detections. Furthermore, AI systems themselves may be vulnerable to adversarial attacks, including through reverse reinforcement learning techniques or malicious data injection.
In addition, the use of AI in cybersecurity raises ethical and regulatory challenges. The issue of liability in case of failure of AI systems is complex and requires careful consideration. Privacy and data protection issues are also crucial, as AI often relies on the analysis of large data sets, which can lead to privacy breaches. In addition, monitoring and control of the use of AI in cybersecurity is essential to prevent abuse and ensure compliance with laws and ethical standards. In this respect, several countries and international organisations are working on regulations and guidelines to regulate the use of AI in cybersecurity.
3- Some guidelines for the responsible and secure use of artificial intelligence
To reap the benefits of AI while minimising the risks, a responsible and secure approach is needed. Collaboration between cybersecurity stakeholders is a key element in achieving this. Sharing information on threats and best practices, cooperating internationally to combat cyber attacks, and establishing common standards and protocols are all initiatives that can help to strengthen global security.
The development of robust and resilient AI systems is also essential. Research into the security of machine learning systems, the design of defence mechanisms against adversarial attacks and the evaluation and certification of AI systems are important avenues for ensuring the reliability and effectiveness of AI-based solutions.
Transparency and explainability of AI algorithms are crucial to build trust and allow a better understanding of the decisions made by AI systems. Efforts to develop more transparent and explainable AI models are essential to ensure the ethical and responsible use of artificial intelligence. Adopting standards of openness and accountability for AI developers can help address these challenges.
Finally, user awareness and training are crucial to create a culture of cyber security and prevent human error. AI-supported education and training programmes, tailored to the specific needs of organisations and individuals, can help develop the skills needed to deal with cyber threats.
4- The uses of artificial intelligence in cybersecurity: advantages and challenges
AI to address the cybersecurity skills shortage
AI can help address the shortage of cybersecurity experts by automating certain tasks and helping professionals to analyse and process data more efficiently.

Machine learning algorithms can analyse transactions in real time to spot suspicious activity and avoid financial losses. Companies such as Feedzai or Forter specialise in detecting and preventing online fraud through the use of AI.
AI and privacy
Artificial intelligence can also be used to enhance privacy and ensure confidentiality of information. For example, AI-based anonymisation or encryption techniques can be developed to protect user data and prevent privacy breaches. AI can also help to detect data leaks and identify the perpetrators, allowing for a quick response in case of an incident.
The evolution of cyber threats and the arms race between AI and cybercriminals
With the increase in cyber attacks and the growing sophistication of the methods used by cybercriminals, it is important to consider how AI can be used to develop new defence strategies. Security researchers need to anticipate future threats and adapt their tools accordingly. It is also important to analyse the risks associated with the arms race between attackers and defenders of artificial intelligence, which could lead to an escalation of cyber conflicts.
AI and cyber risk management
Artificial intelligence can help organisations better understand and assess the cyber risks they face. AI tools can be used to model potential threats, estimate their impact and develop appropriate response plans. This allows businesses and governments to identify vulnerabilities and allocate resources more effectively to strengthen their cyber security.
Regulatory issues related to AI in cybersecurity
Governments and international organisations have an important role to play in developing and implementing AI-friendly cybersecurity regulations. These regulations could include minimum safety standards, certifications and liability mechanisms for AI developers and users. International cooperation is also essential to ensure a globally harmonised and effective regulatory framework.
The ethics of artificial intelligence in cybersecurity
Beyond the regulatory issues, it is important to consider the ethical aspects of using AI in cybersecurity. This may include mass surveillance, fairness and discrimination, as well as issues of liability and consent. Organisations and governments must ensure that the use of artificial intelligence in cybersecurity respects the fundamental rights of individuals, such as the right to privacy and data protection. AI developers should also be aware of the potential biases in their algorithms and work to minimise them to ensure fair treatment of data.
Open source AI solutions and cybersecurity
Open source AI solutions have both advantages and disadvantages when it comes to cybersecurity.
