Security mechanisms in modern IT systems are essential for protecting digital assets, ensuring data privacy, and maintaining system integrity in an increasingly interconnected world. With the rapid growth of cloud computing, distributed systems, and internet-based applications, organizations face a wide range of cybersecurity threats such as unauthorized access, data breaches, malware, and advanced persistent attacks. This study provides a comprehensive overview of key security mechanisms, including encryption techniques, authentication and authorization methods, firewalls, intrusion detection and prevention systems, and security monitoring tools. It also examines the role of multi-factor authentication, identity and access management, and zero trust architectures in strengthening system security. The integration of artificial intelligence and machine learning for threat detection and response is discussed as a modern approach to enhancing security capabilities. Furthermore, the study highlights challenges such as scalability, complexity, evolving threats, and compliance requirements, along with strategies to address them. The findings emphasize the importance of implementing multi-layered and adaptive security mechanisms to safeguard modern IT systems effectively.
