In the computer forensics IRS - Incident Response Systems are the software or hardware products that can alert the user about any type of intrusion to the system or the computer network. Most of the companies or organizations employ the services of Incident Response Systems. It is done to establish a reasonable plan that can address the security breach. The response is completely automated.

This reduces the task of the system administrator. Because of it an alert is generated whenever there is a violation of security. Some of the important features of Incident Response Systems are discussed below. The first among them is Alert Response. The Incident Response Systems lets you to respond to those incidents that are over the network or the computer system. The alert is generated the moment it occurs. It is not affected by any size or type of the event.

Incident Response Systems is integrated with the software and hardware technologies that can monitor and delivers critical information. For the investigators it can help out in timely as well as an efficient manner. Computer forensics investigators can quickly ascertain the things or events that might have taken place.

Those events that might have occured or those that are presently occurring. It is possible to make them active over a single machine or even a group of machines. Incident Response Systems make the analysis of volatile data very easy. It is possible via a IRS to take the action immediately and generate the action based on that information.

It is also possible to even quickly identify all those applications that are running over the system or the machine. Scanning of those applications as well as the ports that are opened is also possible through Incident Response Systems. Any malicious activity can be detected immediately and the action can be taken over it. The action can be manual or automatic depending upon the preference of computer forensics investigator.

Incident Response Systems are capable of integration. A large number of monitoring tools can be integrated via the IRS. These monitoring tools are useless until an alert is generated. There are many manual techniques by the usage of which computer forensics professional can tune the intrusion detection systems. Incident Response Systems can be effective only when intrusion detection systems have already detected some sort of activity.

There are advanced Incident Response Systems which are capable of even detecting any type of intrusions. There can take the action depending upon the type of intrusion. The automated response of Incident Response Systems can be of the type like to store the volatile information from the source if the source is available to the database. Same can be done for destination machines to store it in a database.

The advantage is that the investigator can review it later. IRS can be used to kill a process that is not responding. It can even compare the processes that are running over a machine to the profile of that machine. This is called as Profiling.
