Dealing with Vulnerable Exchange Servers with Gareth Gudger

About Show #880

Is your Exchange server one of the vulnerable ones? Richard talks to Gareth Gudger about the ongoing security concerns around on-premises Exchange servers. The conversation addresses a blog post by the Exchange server team about restricting access of potentially vulnerable Exchange servers to Exchange Online. But, as Gareth explains, this has to do with hybrid Exchange, where your on-premises server can access Exchange Online in a privileged state. What is the right thing to do to limit exploits in Exchange? Keeping up with the latest versions, patching, and ultimately maintaining your entire infrastructure, especially Active Directory - all play a role in securing on-premises infrastructure. Stay vigilant!
