What are the features of intrusion detection system ?

Features of an intrusion detection system are :

Monitoring and Analysis:

• IDS keeps an eye on what users and the system are doing.
• It analyzes activities to spot anything suspicious or unusual.

Auditing System Files:

• It checks and keeps a record of important system files and settings.
• This helps in making sure everything is as it should be.

Assessing File Integrity:

• IDS looks at the integrity of system and data files.
• It ensures that files haven’t been tampered with or corrupted.

Analyzing Attack Patterns:

• It studies known attack patterns.
• If it sees something resembling a known attack, it raises a flag.

Detecting Configuration Errors:

• It finds and alerts about mistakes in how the system is set up.
• This helps in fixing potential vulnerabilities.

Warning of System Danger:

• If the system is at risk or under attack, IDS sends a warning.
• It acts like a security guard, alerting when there’s trouble.
