Mean Time To Detect (MTTD) and Mean Time To Know (MTTK) are two of the most important metrics in security operations. Respectively, they measure the following:
- MTTD: How quickly you can identify something and generate an alert. It determines how fast you’re notified when something suspicious happens anywhere in your cloud or on-premises environment. Today, most security tools keep MTTD low, so you probably receive alerts pretty quickly.
- MTTK: How fast you can sort signal from noise when you get an alert. It measures how efficient the security team is at detecting real threats and understanding what those threats are. The shorter MTTK is, the sooner you will catch an attack in progress and be able to put a stop to it, reducing the negative consequences for your organization.
You can probably see why MTTK is a lot harder to make an impact on. It’s like seeing how fast you can find a needle in a haystack. Difficult, to say the least!
To begin, security teams are barraged with alerts on a daily basis, requiring manual work to sift through the noise to find a signal that indicates a real issue. Add on all the other tasks that need to be done aside from alert investigations, and it’s seemingly impossible to get ahead.
This is where automation comes in. Automation not only eliminates the need to manually handle tedious tasks (like alert response). It also helps you to optimize your existing resources, empowering them to actually focus on MTTK and get it under control.
In this post, therefore, we’ll take a closer look at how the Threat Stack Cloud Security Platform® can help you integrate security into your operations from the start so you can optimize alert handling and significantly reduce your MTTK.
