Enhance SIEM visibility via diversified log monitoring

The OKR intends to improve SIEM (Security Information and Event Management) visibility through diversified log monitoring. Efforts will be directed towards enhancing log correlation effectiveness by 20%, leading to improved threat detection. This will be achieved by training the team on efficient threat detection methods, regular monitoring, and adjustment of correlation rules, along with implementing advanced log correlation tactics.

Next, the goal is to ensure logging is applied to all currently unmonitored network devices. This implies identifying devices not under surveillance, implementing a logging mechanism on each, then checking if the setup functions correctly. The aim is to cover every nook and corner of the network, leaving no room for any security breaches.

Furthermore, the OKR entails the inclusion of diverse log sources into the SIEM system. A richer variety of logging sources will facilitate multidimensional visibility and improved security coverage. However, specific initiatives to achieve this objective are not detailed in the plan.

In summary, the purpose of this OKR is to broaden the SIEM system's visibility and resilience by adopting a more varied log monitoring approach. It provides a roadmap for heightening log correlation effectiveness, extending log coverage across the network and introducing diversity in logging sources.
