 Intrusion detection and prevention systems (IDS/IPS) concepts. Intrusion Detection Systems (IDS) : IDS are like the "guard dogs" of a computer network. They monitor network traffic, searching for any suspicious or malicious activity. When they detect something fishy, they raise an alarm to alert the administrators. IDS can use various detection methods, such as signature-based detection (matching known attack patterns) or anomaly-based detection (identifying deviations from normal network behavior). Intrusion Prevention Systems (IPS) : IPS can be thought of as the "bouncers" of a network. They not only detect intrusions but also take action to prevent them. When an IPS identifies a potential attack, it can actively block the suspicious traffic, drop malicious packets, or modify network configurations to stop the attack in its tracks. Honey Pots : Imagine a honeypot as a "decoy" system, deliberately designed to attract attackers. It mimics vulnerable or va...

  Pros : Open-Source : Snort is an open-source solution, which means it is freely available and can be customized and extended according to specific needs. Network Intrusion Detection : Snort excels at network intrusion detection, providing real-time analysis and alerting for suspicious network traffic, including various types of attacks and exploits. Rule-Based Detection : Snort uses a rule-based detection engine, allowing users to create and customize rules to detect specific patterns or signatures associated with known threats. Active Community : Snort has a large and active community of users and developers, which ensures regular updates, bug fixes, and the availability of additional resources and plugins. Scalability : Snort can handle high volumes of network traffic and can be deployed in both small and large-scale environments, making it suitable for organizations of different sizes. Flexible Deployment : Snort can be deployed as a standalone sensor or as part of a distribut...
