Computer network security is one of the most important challenges in the digital age, and this is where artificial intelligence plays a clear role. AI is used to analyze network behavior and detect abnormal activities. This helps identify cyberattacks at an early stage. Intelligent systems also contribute to preventing breaches and reducing losses. Companies and institutions rely on these technologies to protect sensitive data. Moreover, AI algorithms help develop self-protecting security systems. With the increase in digital theats, artificial intelligence becomes an essential element in network security
