Description: An Intrusion Detection Framework (IDS/IPS) is a structured approach to implementing systems that monitor and analyze network traffic for malicious activities or policy violations. These systems can be classified into two main categories: IDS (Intrusion Detection System) and IPS (Intrusion Prevention System). The IDS focuses on detecting and alerting potential intrusions, while the IPS not only detects but also takes measures to prevent those intrusions from affecting the network. IDS/IPS utilize various techniques, such as signature-based detection, which identifies known attack patterns, and anomaly-based detection, which looks for unusual behaviors in network traffic. Implementing an intrusion detection framework is crucial for cybersecurity, as it enables organizations to quickly identify and respond to threats, thereby minimizing the risk of damage to their systems and data. Additionally, these systems are essential for compliance with security regulations and audits, providing a detailed record of network activities and helping organizations strengthen their security posture.
History: The concept of intrusion detection began to take shape in the 1980s when researchers started developing systems to monitor access to computer systems. One of the first IDS systems was the ‘Intrusion Detection Expert System’ (IDES), created in 1987 by Dorothy Denning and her team. Over the years, the technology has evolved, incorporating more advanced techniques such as behavioral analysis and machine learning. In the 1990s, IPS systems began to emerge, allowing not only detection but also active prevention of intrusions.
Uses: IDS/IPS systems are primarily used in network environments to protect sensitive data and ensure system integrity. They are applied across various industries, including finance, healthcare, and telecommunications, where information security is critical. Additionally, they are key tools in incident response, allowing security teams to identify and mitigate threats in real-time.
Examples: An example of an IDS system is Snort, which is a widely used open-source software for intrusion detection. On the other hand, an example of an IPS system is Suricata, which not only detects intrusions but can also block malicious traffic in real-time. Both systems are used by organizations to enhance their cybersecurity.
