Intrusion Detection
Intrusion Detection is a type of security management system for computers and networks. An Intrusion Detection system gathers and analyzes information from various areas within a computer or a network to identify possible security breaches, which include both intrusions (attacks from outside the organization) and misuse (attacks from within the organization). Intrusion Detection uses vulnerability assessment (sometimes referred to as scanning), which is a technology developed to assess the security of a computer system or network. Intrusion detection functions include:- Monitoring and analyzing both user and system activities
- Analyzing system configurations and vulnerabilities
- Assessing system and file integrity
- Ability to recognize patterns typical of attacks
- Analysis of abnormal activity patterns
- Tracking user policy violations
The safeguarding of security is becoming increasingly difficult, because the possible technologies of attack are becoming ever more sophisticated; at the same time, less technical ability is required for the novice attacker, because proven past methods are easily accessed through the Web.
Typically, an Intrusion Detection system follows a two-step process. The first procedures are host-based and are considered the passive component (or Host-based Intrusion Detection). These include: inspection of the system's configuration files to detect inadvisable settings; inspection of the password files to detect inadvisable passwords; and inspection of other system areas to detect policy violations. The second procedures are network-based and are considered the active component: mechanisms are set in place to reenact known methods of attack and to record system responses.
