SIEMs are now creating the majority of security operations alerts, and less than 1% of the severe/critical alerts are actually being investigated. Instead of just addressing the highest rated alarms, SecOps needs a way to review and validate all alerts and potential threat campaigns.
It is logistically impossible to manually review and investigate all SIEM alerts. The original alarms typically don’t contain enough information to confidently take action, so the cases will require additional, time-consuming research and enrichment. Following the documented playbook processes, the SecOps analyst will likely only be able to investigate a small percent of the alerts in the queue. This increases the opportunity for a successful attack.
Automate as much of the incident response playbook as possible and enrich the case with investigation results with Allesao Managed SAO. Here is an example workflow using Active Directory, a SIEM, Threat Intelligence and Endpoint Detection & Response tools.
Without adding resources the security operations team will be able to automate 80-90% of their alerts, allowing them to handle a higher volume of alerts with accuracy. For the remaining alarms that need human intervention, the analysts will benefit from having the automated case enrichment data already in the Allesao record. This not only saves time, but also improves workflow consistency. Automating your workflows with Allesao improves team efficiency, reduces threat risk and increases your overall security posture.
