SIEM – Security software options.

Security Information Event Management, or SIEM for short, can provide real-time analysis of your network and create alerts to catch intruders in the act. There are many options available,but all basically do the same thing and are great options for combatting cyber attackers.

How does a SIEM work?

A SIEM combines many technologies on your network to provide you a full real-time view of everything happening. It centralizes security management to one system by correlating logs from many technologies. Using different alert types based on what’s happening and the severity, a SIEM can be an indispensablecybersecurity tool for any network.

Log Management?

The SIEM pulls all the logs from your network devices, such as security, network, databases, servers, and endpoints,so you don’t avoid critical alerts. With that information, it can follow an attack and see it in real-time and how it’s moving through your network. Alerts are generated to a security analyst,andthen the attack can be stopped. The SIEM is generally monitored through dashboard views, which provide charts or graphs to show network devices status. Additionally, the logs can be stored centrally for compliance purposes or digital forensics after an attack. Hackers generally attempt to clear logs after an attack, but a SIEM will ensure that critical logs are centrally stored in a secure place.

Biggest reasons to use a SIEM

SIEMs provide a lot of benefits to any security plan and can give your security team a tool to detect attacks never seen. Zero-day threat detection of a SIEM can detect activity that other device can’t. The SIEM will detect activity that generally happens during an attack versus detecting the attack itself. Another advantage is the ability to monitor for Advanced Persistent Threats (APT), which are threats that have a foothold on a network and go undetected for a long time. The SIEM can set thresholds on traffic and discover when an anomaly is occurring and alert you to it. This might happen if a specific computer starts transmitting larger than reasonable amounts of data out of a network. Finally, having a SIEM to recreate attacks with captured logs and help investigators retrieve this information for digital forensics is an excellent insurance post-mortem. After an attack, recovering and finding lessons learned can help prevent future attacks and alert others to threats. Having a SIEM can require someone to monitor it constantly or another option is outsourcing a Security Operations Center (SOC) support. This can be an excellent option to have the same level of security without the need for a full-time security staff maintaining these tools.
