What is Intrusion Detection Analysis?
Intrusion Detection Analysis is the process of monitoring and analyzing network traffic, system logs, and other activity to identify unauthorized access, suspicious behavior, or potential security threats within a network or system. This analysis is performed using Intrusion Detection Systems (IDS), which come in two main types: network-based (NIDS) and host-based (HIDS).
Key components of Intrusion Detection Analysis include:
- Signature-Based Detection: This method relies on predefined patterns or signatures of known threats. It’s effective for recognizing well-known attacks but can miss new or evolving threats (zero-day attacks).
- Anomaly-Based Detection: This approach detects unusual behavior by comparing current activity against a baseline of normal operations. It is effective in identifying novel attacks but may generate more false positives.
- Behavioral Analysis: It focuses on user and system behavior patterns to spot abnormal actions that could signal a threat.
- Correlation of Events: Multiple alerts from various sources are analyzed together to determine if they represent a coordinated attack or a more serious issue.
- Incident Response: Once an intrusion is detected, the system triggers alerts to notify the security team for immediate action, helping to minimize potential damage.
Intrusion Detection Analysis is crucial in maintaining the integrity and security of IT infrastructures, allowing organizations to detect and respond to cyber threats proactively
