excess IDS
1. Monitoring and analysis of system and user prolaku
2. Tests on the system security configuration
3. Provide a reference implementation of the security system
4. Handling an attack against a known pattern
5. Handling of abnormal activity patterns
excess
limitations of IDS
1. Less quickly recognized the attack on the segments that
have great traffic and processor load large
2. Unable to identify a new technique that is not in the
data base on the pattern of the attack held
3. Not able to work effectively on a network switch-hubs

Strategy and tactics of computer security
1. physical Security
2. computer lock
3. Security bios
4. Safety boot loader
5. Xlock and vlock
• xlock: X display lock on linux
• vlock: a small program to lock some or all of the virtual
