IDS/IPS systems

Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) are cybersecurity systems that aim to detect and prevent intrusions and other security threats in the network environment.

Intrusion Detection System (IDS)

Intrusion Detection System (IDS) is a cybersecurity system that monitors network traffic and system events to search for signs or abnormalities that may indicate a security breach or cybersecurity risk. IDS can use multiple methods to detect possible attacks, including:

1. Signature-based analysis: IDS compares network traffic or system events to known attack patterns or signatures. If it detects a match, it generates an alert.
2. Abnormality monitoring: IDS analyzes normal activity and looks for deviations from normal behavior. Abnormalities may be signs of possible attacks.
3. Protocol analysis: IDS monitors network traffic and system events to ensure compliance with network protocol standards. Deviations may indicate potential attacks, such as malicious network traffic or protocol misuse.

Intrusion Prevention System (IPS)

Intrusion Prevention System (IPS) is a more aggressive variation of IDS, as it not only detects intrusions and security risks, but also actively works to prevent them. IPS can respond to detected threats in several ways:

1. Prevention: IPS can prevent access to the network or specific resources based on identified attacks or suspicious activity.
2. Packet filtering: IPS can analyze and filter network traffic according to identified attacks or rules.
3. Connection termination: IPS can reset or terminate suspicious connections automatically.

Snort

Snort is an open source IDS / IPS system that uses signature and anomaly-based detection. It is able to monitor network traffic in real-time and identify known attack patterns or deviations from normal network traffic. Snort is a highly flexible and scalable system, and it provides a wide range of configurable features. Snort can act both as a standalone system and as part of a broader security architecture.
