I've been working to modernize our Cyber Security Operation Center (SOC) response time service level objectives (SLOs). Like many organizations, we've seen the goal of the "1 : 10 : 60" which aims to have SOCs "detect" an event within 1 minute, "analyze" within 10 minutes, and "contain" within an hour. For a variety of reasons, we set less aggressive targets --- aiming at 15/60/240 minutes for these objectives. Might other organizations be willing to share/discuss their actual SLOs and target objectives for SOC performance?

I have seen the “1:10:60” goal for improving SOC response times to be a popular target for many organizations. However, depending on your particular needs and resources, this target may not always be attainable. We have set less aggressive targets of 15/60/240 minutes for SOC performance, and these have worked for us in the past.
For SOC services, looking at the criticality of operations, it is better to set very aggressive SLOs which are "1:5:30". This will help to contain actions against critical alerts and meet SOC performance objectives.
