Monitoring the security of Microsoft Exchange Servers has become increasingly crucial due to rising cyber threats, as demonstrated by the recent zero-day vulnerability exploited in targeted attacks on Exchange on-prem installations. This vulnerability, announced by Microsoft in mid-March 2021, had potentially been exploited since January, affecting a wide range of users, including enterprises and financial institutions. The complexity and impact of such breaches necessitate robust log monitoring and security measures, as traditional security tools often fail to cover zero-day exploits. Coralogix offers a comprehensive solution for monitoring and responding to such threats by integrating with Windows Event Viewer and utilizing machine learning to detect anomalies, offering geo-enrichment of IP data, and providing extensive visualization options for post-breach analysis. The importance of understanding, mitigating, and analyzing security breaches is emphasized, pointing out that organizations must equip themselves with effective monitoring tools to manage and mitigate the impact of such vulnerabilities effectively.
