Definitions and General Info
Security Information Management (SIM) is the industry-specific term in computer security that refers to the collection of data (usually log files, such as event logs) into a central database for trend analysis. The data used by these systems usually comes from various security devices, e.g. firewalls, proxy servers, intrusion-detection systems and antivirus software. A SIM program translates that data into correlated and simplified formats, which are similar to those of network-management software. A SIM often normalizes that data into a common format, to allow better processing, such as through correlation analysis.
In general, a SIM tool comprises of server software, agents installed on security devices or on servers, and of course a central management console. All that software monitors the system for abnormal behavior and provides reports to the user based on its analysis. As the Security Information Management software’s information has to do with event data mainly, SIM programs are often called Security Event Management (SEM) tools.

Main Advantages of SIM Software
All the information that security programs acquire and store in their logs often amounts to very large quantities, making it infeasible for someone to process it properly. In addition, the cost of a security breach in a system can be quite high, especially if the system at hand contains sensitive data (often irreplaceable). Therefore, the need of a program to manage all that becomes apparent. A SIM program does exactly that and is an essential component of any organization’s computer systems.
However, there is more to the story. A SIM also provides reports, which allow the user to have an understanding of what is happening, and in some cases take action. With the intrusion attempts growing more and more sophisticated and in larger numbers, often the specialized security software being used may miss certain compromises of security, which don’t comply with the known hacking attack / virus signatures. However, a SIM may capture this event and, even if it doesn’t sound an alarm, it may bring it to the user’s attention for further examination.
Finally, a SIM program is more reliable in its alerts than a single computer security device. This is because it takes into account various sources and compares the output of each one of them with the others.

Security Information Management software can make a big difference to your computer system, especially if you handle a lot of sensitive data that may attract intruders or malicious software. Although such a program cannot solve all your computer’s problems, it can help a lot in its protection and offer you some peace of mind.
