Security information management collects security data in one place for trend analysis and detecting strange events on a computer network. Event logs are the most typical form of data collected, and a trained technician is critical for effective management.
Security information management is the process of using software to collect data about security systems on a computer. The intent of this process is to collect all security data in one place, allowing for trend analysis and other forms of data correlation. This allows security administrators to detect any strange events on the computer network, which could indicate a possible system breach. Alternatively, security information management can simply be used to ensure that everything is working as intended on the network.
Event logs are the most typical form of security data collected when managing security information. An event log is a file on your computer that records important events about your system; in terms of security, this could include a list of people who have logged into the network on a particular date, along with the length of the session and the usernames used to log in. When managing security information, event logs from various computers on the network are collected together by security software. A technician then funnels the data, looking for trends or other types of bizarre events that could indicate problems on the system. Looking at logs together can often illuminate trends that might otherwise go undetected.
For example, analyzing every log on the network might uncover the fact that the same employee is logged on to two different computers at the same time. If your network is configured not to allow duplicate access, this can demonstrate that a specific network feature is not working properly or has been disabled through malicious tampering. Without focusing the logs on security information management, this issue may never come to light.
The ability of the technician hired to review logs is critical to the effectiveness of security information management. Without a trained technician familiar with network parameters, many of these seemingly innocent problems may go unnoticed. For this reason, the effectiveness of security management depends not necessarily on the software, but above all on the competence of the person in charge of reviewing the data.
