The news of active exploitation of the Microsoft Exchange Server vulnerabilities has highlighted the importance of network visibility in securing critical server infrastructure. Microsoft has quickly patched vulnerabilities, but there remain important points to note.
First, the general class of server-side request forgery (SSRF) attacks that were used against Microsoft Exchange Server in this case can also target other public-facing services, possibly turning servers into new threat vectors that bypass your perimeter defenses. That makes clear that network visibility and decryption are central to securing public-facing infrastructure. Second, monitoring and securing Microsoft Exchange Server has its own set of unique challenges that administrators and security analysts need to be aware of.
