In the modern era, everything is transformed onto online platforms whether
it is a transaction of money, sending information from one system to another, e-mails,
business plans, trading, etc. Every passing minute, a huge amount of data is generated,
processed, and executed. Cybersecurity is a field of computer science that deals with
the protection of all these things over the internet and machine learning techniques are
playing an important role in identifying threats. This chapter is focused on describing
the role of machine learning in the detection of intrusions present in the system so that
sensitive data can be protected. By analysing a huge amount of data, AI can identify
hidden patterns and behaviours that help in building more proactive measures.
