A Security Information and Event Management (SIEM) system collects, manages, and correlates security data from firewalls, endpoints, and security systems in an organization’s digital environment. The centralized log files, events, and security alerts are then monitored by security analysts in a security operations center (SOC) for suspicious activity and signs of possible threats within an organization. SIEM is an essential technology – but how much is too much when it comes to the number of alerts?
Sometimes it’s possible to have too much of a good thing. Consider a SIEM, for instance. A SIEM can be a security analyst’s best friend or worst nightmare depending on the volume and quality of alerts it produces.
Alert fatigue is real, and in cybersecurity, it occurs when individuals are exposed to frequent and large volumes of alerts – so much so that they become desensitized to the “noise.” The problem is that real threats can be hidden amid the persistent flood of false positives – and can be easily missed by analysts that are overwhelmed by the constant barrage.
Fortunately, alert fatigue can be prevented. Following are six ways to ensure that your SIEM is producing the right volume and quality of alerts for your security or SOC team and your organization:
A SIEM is a helpful tool and assists analysts in the heavy-lifting process of detecting and responding to threats. Just like any other tool, though, it does not work without human intervention. Processes, including regular maintenance, should be in place to ensure that the SIEM is producing quality alerts for effective detection by skilled SOC analysts. But it’s a delicate balance. Monitoring, review, and tuning should be performed regularly so you get the right amount of a good thing.
