How AI can Enhance Cybersecurity?
For all these reasons, the cybersecurity industry is turning its attention to artificial intelligence. Here are some examples of how his AI is being used in cybersecurity.
1. AI-Powered Threat Detection
AI is used to detect and analyse threats in real-time, providing a faster and more effective response to cyberattacks. AI algorithms can analyse large volumes of data, identify patterns, and detect anomalies that may indicate a cyber attack. AI-powered threat detection helps cybersecurity professionals easily identify new and emerging threats, as well as known threats that have already been identified. This can help improve their ability to respond to cyberattacks and prevent them from causing damage or data theft (Source: Markets and Markets).
2. AI-Powered Authentication and Access Control
AI is used to enhance authentication and access control processes, making them more secure and efficient. AI algorithms are trained to analyse user behaviour patterns to determine whether a user is authorised to access a particular resource. This is especially helpful in identifying the victims of social engineering or hackers pretending to be someone else. This prevents unauthorised access and reduces the risk of data breaches. Having such an AI system is useful for all kinds of businesses, including their infrastructure, server rooms, websites, data storage systems, and even their computers. AI-powered authentication and access control can also reduce the burden on IT staff, who would otherwise need to manually manage access control policies.
3. AI-Powered Threat Response and Remediation
AI is used to automate threat response and remediation processes, reducing the time and effort required to respond to cyber-attacks. Thus, cybersecurity professionals will have time to deal with other important cybersecurity measures. These AI algorithms can be programmed to automatically quarantine infected devices, block malicious traffic, and remove malware from infected systems. This minimises the impact of cyberattacks and prevents them from spreading to other systems. This is a valuable tool for network engineers and operators as well, as they are not required to monitor the network all the time. AI-powered threat response and remediation reduce the workload of IT staff, who would otherwise need to manually respond to cyber attacks, limiting their effectiveness.
These are only a handful of AI applications in the cybersecurity industry. However, with increasing technological advances in AI, you can expect better AI cybersecurity tools and systems in the future.

Challenges of AI in Cybersecurity
1. Adversarial Attacks on AI Systems
Adversarial attacks are a type of cyberattack that is specifically designed to evade AI-powered security systems. Adversarial attacks work by introducing small, subtle changes to data that are designed to fool AI algorithms into misclassifying data or making incorrect decisions. Adversarial attacks can be used to bypass AI-powered threat detection systems, compromise authentication and access control systems, and undermine AI-powered threat response and remediation systems. As AI-powered security systems become more common, adversarial attacks are likely to become more sophisticated and difficult to detect. If a cyberattacker knows the training data, construction, and limitations of a cybersecurity AI tool or system, they can develop sophisticated adversarial attacks on these systems by developing viruses or Trojan horses for the system, as they will know the blind spots of AI. This is why AI systems must be constantly updated and audited by cybersecurity professionals. As cyber criminals are ever adapting and advancing with new tools, especially with their own AI tools, you can only predict a clash of AI systems in the cybersecurity industry in the future (Source: CNBC).
2. Lack of Transparency and Explainability in AI Algorithms
One of the challenges of using AI in cybersecurity is the lack of transparency and explainability of AI algorithms. AI algorithms are often complex and difficult to understand, making it difficult to determine why a particular decision was made or how a particular result was achieved. This lack of transparency and explainability can make it difficult to trust AI-powered security systems and can lead to concerns about bias and discrimination. Moreover, the training datasets for such AI systems can themselves be contaminated with intentional errors to mislead the algorithms. The presence of errors can further the AI's tendency to make undesirable decisions regarding sensitive data. To overcome this challenge, researchers are working to develop more transparent and explainable AI algorithms. However, it is unlikely that humanity will understand the complex decision-making of AI systems shortly.
3. Ethical Concerns related to the use of AI in Cybersecurity
Another challenge of using AI in cybersecurity is the ethical concerns that can arise from its use. AI-powered security systems have the potential to collect and analyse vast amounts of data, raising concerns about privacy and data protection. As you have seen with AI painters plagiarising content from other creators, AI cybersecurity tools might also be risky in protecting sensitive data sets. There are also concerns about the potential for AI-powered security systems to be used for surveillance and monitoring purposes, which could infringe on individual rights and freedoms. To address these concerns, it is important to develop AI-powered security systems that are transparent, accountable, and respectful of individual rights and freedoms. However, as governments, cybercriminals, and anarchists are already using sophisticated AI tools to monitor and store network traffic, surveillance is hard to evade.
