Information Security: Denial of Service (DOS) Attack and Intrusion Deduction System

Denial of Service (DOS): It is an Attack on the Availability of network resources

Ways to Intitiate the DOS are :-

1. Transmission Failure
2. Traffic Redirection
3. DNS Attack
4. Connection Flooding

Types of Connection Flooding Attack

4. SYN Flood
5. Teardroop

Distributed Denial of Service Attack (DDoS): When a attacker uses a convenient method to distribute trojan horses to as many target machine  possible 

Security

Intrusion Detection System (IDS) : It is a device that monitors and deduct the suspicious events

Terminology used in IDS

• Anomaly
• Misuse
• Intrusion
• Audit
• Profiling

Goals of Intrusion Deduction System

• Detect Attach properly
• Monitor System Effectively with minimal resources

Response of IDS

• Monitor the Attack
• Protect system and reduce exposure
• Alter a human
