The Role of Artificial Intelligence in Enhancing Cybersecurity

Artificial Intelligence (AI) is revolutionising the field of cybersecurity, providing advanced tools and techniques to combat the ever-evolving threat landscape. With the rapid growth of cybercrime and the expanding attack surface, organisations are turning to AI-powered solutions to analyse vast amounts of data and identify complex threats. In this article, we will explore the advantages of AI in cybersecurity, the potential downsides, and how AI can be effectively employed to protect against cyber threats. 

Advantages of AI in Cybersecurity

AI offers numerous advantages and applications in the realm of cybersecurity. As traditional software systems struggle to keep up with the sheer volume and sophistication of cyber threats, AI and machine learning (ML) algorithms excel at detecting new and emerging threats. By leveraging sophisticated algorithms, AI systems can identify malware, recognise patterns, and detect even the most subtle behaviours associated with cyberattacks.

1. Detecting New Threats

One of the key advantages of AI in cybersecurity is its ability to spot and analyse new threats. Unlike traditional software, which relies on predefined rules and signatures, AI systems continuously learn and adapt based on real-time data. Through natural language processing and data scraping, AI can gather information from articles, news, and studies, providing intelligence on emerging anomalies, cyberattacks, and prevention strategies. This enables organisations to stay ahead of cybercriminals who are constantly evolving their tactics.

AI-based cybersecurity systems also excel at prioritising risks by leveraging global and industry-specific threat intelligence. By analysing a vast array of data, these systems can determine which threats are most likely to be used against an organisation's systems. This empowers organisations to allocate their resources effectively and bolster their defences against the most probable attack vectors.

2. Battling Bots

Bots represent a significant portion of internet traffic and pose a serious threat to organisations. From account takeovers to data fraud, bots can wreak havoc if left unchecked. AI and machine learning technologies provide the means to distinguish between good bots (such as search engine crawlers) and malicious ones. By analysing website traffic patterns, AI can identify risky behaviours and flag potential bot activity. This allows organisations to stay ahead of the game and proactively defend against automated threats.

According to Mark Greenwood, Chief Technical Architect & Head of Data Science at Netacea, AI-powered systems can uncover the intent behind website traffic, helping organisations identify and mitigate the risks associated with bad bots. By analysing behavioural patterns, businesses gain insights into what constitutes a normal user journey and what deviates from the ordinary. This proactive approach enables organisations to take swift action against potential threats and maintain a secure online environment.

3. Predicting Breach Risks

AI systems excel at predicting breach risks by analysing an organisation's IT asset inventory and threat exposure. By maintaining an accurate and detailed record of devices, users, and applications with varying levels of access, AI-based systems can identify vulnerabilities and allocate resources to areas of highest risk. Armed with prescriptive insights derived from AI analysis, organisations can enhance their controls and processes to reinforce their cyber resilience.

With the increasing number of remote devices in today's work environment, AI plays a crucial role in securing endpoints. While traditional antivirus solutions and VPNs are effective against known threats, they often rely on signature-based detection. This approach falls short when facing new and emerging malware attacks. AI-driven endpoint protection takes a different approach by establishing a baseline of behaviour for each endpoint, continuously learning and adapting to detect anomalies. By flagging unusual activities and taking proactive action, AI-powered solutions provide robust protection against threats, minimising the reliance on signature updates.

The Perspectives of Cybersecurity Executives

The use of AI in cybersecurity has gained significant traction among cybersecurity executives and experts. According to a report by the Capgemini Research Institute, 76% of enterprises have prioritised AI and machine learning in their IT budgets. The rapid adoption of AI is driven by the need to analyse and mitigate the increasing volume of data generated by connected devices and to enhance the speed and accuracy of threat detection.

The report also highlights key takeaways from the survey of 850 cybersecurity executives across 10 countries.

• Faster Response to Breaches

Three out of four surveyed executives believe that AI enables their organisation to respond more rapidly to breaches. AI-powered systems can automate incident response, providing real-time insights and enabling security teams to take swift action.

• Necessity of AI for Cyberattacks

69% of organisations consider AI to be a necessary tool for responding to cyberattacks. The ability of AI to analyse vast amounts of data and detect patterns beyond human capability is crucial in combating sophisticated cyber threats.

• Improved Accuracy and Efficiency

Three in five firms reported that AI improves the accuracy and efficiency of their cybersecurity analysts. By automating routine tasks and providing insights into emerging threats, AI enables analysts to focus on more critical issues and make informed decisions.

Despite the positive reception of AI in cybersecurity, it is crucial to recognise the potential downsides and ethical implications. Organisations must invest in robust AI systems that are trained using diverse and reliable data sets to avoid false positives and incorrect results. Additionally, the misuse of AI by adversaries is a concern, as they can leverage AI technologies to enhance their attacks, spread malware, and engage in social engineering tactics.

The Ethical Use of AI in Cybersecurity

While there are potential dangers associated with the misuse of AI, it is important to acknowledge that AI can also be a powerful tool in protecting against cyber threats. AI has the potential to enhance cybersecurity practices and enable organisations to proactively defend against attacks. Here are some ethical use cases of AI in cybersecurity.
