What is the Intrusion Detection:

What is the Intrusion Detection Intrusions are the activities that violate the security policy of system. Intrusion Detection is the process used to identify intrusions.

Types of Intrusion Detection System :

Types of Intrusion Detection System Based on the sources of the audit information used by each IDS, the IDSs may be classified into Host-base IDSs Distributed IDSs Network-based IDSs

Types of Intrusion Detection System :

Types of Intrusion Detection System Host-based IDSs Get audit data from host audit trails. Detect attacks against a single host Distributed IDSs Gather audit data from multiple host and possibly the network that connects the hosts Detect attacks involving multiple hosts Network-Based IDSs Use network traffic as the audit data source, relieving the burden on the hosts that usually provide normal computing services Detect attacks from network.

Who? :

Who? Trustwave Symantec

What operating System?:

What operating System? Windows Linux Mac
