Are you using your #SIEM to detect #security threats in the most efficient and effective ways possible❓🤔 When you implement and fine-tune SIEM detections, you strengthen your security posture and become better able to strategically aligning with your business objectives. Fine-tuning your SIEM detections specifically allows you to: 💡 Improve threat detection with smarter correlation ⬆️ Accelerate incident response 👀 Gain comprehensive visibility into your environment ☑️ Enable compliance and audit readiness 😌 Reduce alert fatigue Read on, to learn about 6 specific steps you can take that will help you build fine-tuned detections and high-fidelity alerts.👇 https://lnkd.in/g7USiCNn #ThreatDetection #IncidentResponse #TDIR #CyberSecurity

Should you use supervised #AI for your SOC? 🤖 👀 Yes! When applied to first-pass alert triage, it strengthens the human decision layer rather than removing it — so it's a win-win. 🌟💪 It helps by prioritizing alerts based on how similar events were previously validated by analysts. Let's talk some more about supervised AI. In our latest blog you can dig into the details of: 👉 Supervised AI for first-pass triage 👉 Why analyst attention is a limiting factor 👉 How supervised AI works by reflecting human judgment 👉 Why the ROI case is straightforward ➕ And more https://lnkd.in/gzhHJbkh #Security #CyberSecurity #SecurityOperations

❄️ Winter break is the perfect time to brush up on your Sigma rules! ❄️ With Sigma Specification 2.0 rules, #security teams can create vendor-agnostic detections without being limited by proprietary log formats. 🙌 So, security teams now have: ✅ New fields and modifiers that improve how security teams use the rules ✅ Correlation specifications to extend rules to more sophisticated detections ✅ Filters that reduce false positives ✅ #JSON schema to allow automation Learn more about the key changes in Sigma v.2.0 and supporting Sigma v2.0 mapped to MITRE ATT&CK framework. https://lnkd.in/gzT_52Sa #SigmaRules #CyberSecurity #SIEM #InfoSec

💡 As you build out your #security program, you should know some of the more critical #Windows Event IDs to monitor and what they mean. Read on to get a list of critical Event IDs for: 👉 Logon events 👉 Privilege use 👉 Windows Server 👉 Microsoft Defender Antivirus Plus, learn how you can build a single source of log information that enables observability and visibility across your environment. 🙌 https://lnkd.in/ge4vsmtZ #CyberSecurity #SIEM #InfoSec #GraylogLabs
