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.

Exclude certain CIS (sca) rules from agents
There is currently no feature for excluding specific SCA rules however this feature has been requested here and would be added to the roadmap for future releases.

Greenbone
I use Wazuh instead. Greenbone CE is severely limited and requires payment for anything beyond the very basic. Super simple installation more features.

Update vulnerability databases through proxy with authentication
Seems like something that should be documented somewhere more official than a random reddit post for sure. Added it to https://github.com/wazuh/wazuh/issues/1112 for good measure.

💻 Introducing Wazuh 4.7.0.
Hmm, I've really been wanting to try Wazuh but since all our endpoints (Win10/11) are running a German locale I've run into https://github.com/wazuh/wazuh/issues/16842 when checking the compliance checks (CIS benchmarks) on a test installation of 4.6.

Risks of hosting a website out of my house
Monitoring & Active Measures - Exporting firewall events to an external time-series database like I describe above is good to see who is touching your firewall or accessing your web site. Using an Intrusion Detection System / Intrusion Prevention System (IDS/IPS) such as open-source Suricata, which is a free package on pfSense, and deploying file system integrity monitoring, such as the open-source Wazuh on the exposed server are also good approaches to protecting yourself.

Ignore Vulnerability for specific CVE?
We are actively working on enhancing the system to allow users to mark vulnerabilities as "not vulnerable" or hide them. You can track the progress of this enhancement on the following GitHub issue: (Enhancement - Mark Vulnerabilities as Not Vulnerable).

advice on building a vulnerability management dashboard
Hello, thanks for using Wazuh, I will try to answer your questions: 1- I am going to check with the team in charge to see if there is a way. 2- Untriaged is a default value that is placed on vulnerabilities that do not have low, medium or high values https://github.com/wazuh/wazuh/issues/12675 3- As in the previous point, the providers of vulnerability lists have not provided the data.
