should we write our own custom rule
I am currently employed as a cyber analyst, and we've recently implemented an Endpoint Detection and Response (EDR) system. Upon closer inspection, I've observed that numerous events are not being flagged as alerts. This raises a crucial question: should I take the initiative to create custom rules to ensure these events are brought to our attention, or should I rely solely on the EDR's intrinsic capabilities to detect and classify threats? As a potential solution, I'm contemplating the implementation of rules based on Sigma, such as those available at the following repository: here. Your insights and experiences on the effectiveness of this approach would be greatly appreciated. Thank you for your time and assistance.

Installed Graylog. 7 million log entries per month. Now what?
Depending on whether this is up your alley either look for a MSSP/MDR/Managed BlaBla provider or head on to - https://github.com/splunk/security_content - https://www.elastic.co/guide/en/security/current/prebuilt-rules.html - https://github.com/mdecrevoisier/SIGMA-detection-rules - https://github.com/Azure/Azure-Sentinel to get an idea of what to look for. MITRE ATT&CK and the related DETT&CT should serve as an additional eye opener. Ah yes - forgot the bible on log management from Anton Chuvakin in the above list.
