🔍 𝐄𝐱𝐩𝐥𝐨𝐫𝐢𝐧𝐠 𝐒𝐈𝐄𝐌 𝐚𝐧𝐝 𝐂𝐨𝐫𝐫𝐞𝐥𝐚𝐭𝐢𝐨𝐧 𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬 𝐎𝐯𝐞𝐫 𝐭𝐡𝐞 𝐘𝐞𝐚𝐫𝐬 🔍 Back in 2016, I addressed a critical issue in the realm of SIEM: the challenge of correlating events based on periodic queries. My insights were published in Turkish as "Log Yönetimi, Korelasyon ve SIEM" (Log Management, Correlation, and SIEM). You can read the full article here: https://lnkd.in/ghd7naG Interestingly, just a day later, a related article titled "SIEM tricks: dealing with delayed events in Splunk" was published, highlighting similar concerns. Check it out here: https://lnkd.in/gz4KyPkV Fast forward to 2021, I revisited this topic on PeerSpot, delving deeper into the persistent issues surrounding event correlation in SIEM systems. For those interested, you can read more about it here: https://lnkd.in/gcEVjKCS Happy reading and feel free to share your thoughts! #CyberSecurity #SIEM #Correlation #LogManagement #ThreatDetection #Splunk #PeerSpot #InfoSec

🚀 Why is SureLog SIEM Different from the Rest? 🚀 While most SIEM solutions limit you to a 90-day default retention period, SureLog SIEM offers a staggering 900 days—with the same disk size! That’s 10x more historical data for deep threat analysis and compliance. 💥 Here’s why SureLog SIEM truly shines: 🔍 Powerful Correlation Engine + UEBA Models Our advanced analytics and User Entity Behavior Analytics (UEBA) models detect anomalies early, ensuring that threats are identified before they can cause any harm. 🛡️ Security Benchmarking & Vulnerability Scanning Proactively identify vulnerabilities with integrated security benchmarking and vulnerability scanning, which automatically feeds into our correlation engine for more effective threat detection. 💻 Asset Discovery for Enhanced Security We combine asset discovery with correlation. Detect unauthorized SNMP requests to non-SNMP devices or traffic towards non-existent ports in real time—these are just a few example rule cases. With these features, SureLog SIEM is one of the most comprehensive commercial SIEM products available. Ready to take your cybersecurity to the next level? 🔒 #SIEM #Cybersecurity #ThreatDetection #UEBA #LogManagement #SureLogSIEM #VulnerabilityScanning #Security

🔹 SIEM focuses on collecting, aggregating, and analyzing logs and metrics from various data sources, such as endpoints, applications, and IAM. This powerful tool provides real-time alerts, helping organizations detect anomalies and potential threats. 🔹 SOAR goes a step further by adding automation and incident response management. With SOAR, teams can streamline their case management, automatically respond to incidents, and reduce response times, ultimately boosting overall efficiency. In short: 1️⃣ SIEM = Detection & Alerts ⚠️ 2️⃣ SOAR = Automation & Response 🤖 These tools create a more robust defense mechanism, allowing security teams to focus on what matters most. 🔐 #cybersecurity #SIEM #SOAR #infosec #securityoperations #digitaltransformation #MicrosoftSentinel #automation #incidentresponse

Over the past decade, we've witnessed a paradigm shift in SIEM log management. From "log everything" to "budget-conscious data selection," we now prioritize meaningful data collection. Let's explore some effective strategies for optimizing your log collection: - Process Events: Consider filtering out AuditD and WinEventLog process launches (looking at you, Event ID 4688) for known agents in your environment. If you aren't baselining your agents activity, then it provides no additional value. - Network Scanning: Do you really need scanner traffic from the firewall in your SIEM? Focus on results from the scanner, and remove noise in the firewalls. - DNS Data: Not all DNS lookups are created equal. Filter out common domains and consider cheaper storage for internal DNS data. These strategies come with trade-offs. Balancing visibility against costs is a key responsibility for security leadership. By critically evaluating our data collection practices, we can make room for more valuable data sources and improved detections. The era of "log everything" is behind us. How are you optimizing your SIEM data collection? Share your strategies in the comments! #Cybersecurity #SIEM #DataManagement
