In the wake of the attacks on Microsoft Exchange Servers, many business leaders are asking about server management. What went wrong with on-premise security in the case of Microsoft? How can better virtual server management stop similar attacks in the future?

Below are best practices:

1. Prevent server sprawl. The term ‘server sprawl’ refers to the notion of owning so many servers that they’re tough to keep tabs on.

In the days of old, IT teams needed to obtain servers through long and beurocratic business processes. Now, IT employees can easily request virtual servers via online portals. This means that you may have servers on your system that are no longer needed and that aren’t properly secured.

Search your system for unmanaged virtual servers. Catalogue them and decide on whether to keep them, to lose them and/or to secure them.

2. Apply zero-trust. Ensure that appropriate permissions are granted to virtual environment admins. Beyond that, ensure that permissions can also be easily revoked in the case of dismissed employees. Enable quick audit features for permission information processing.

3. Backup virtual servers. Prevent data loss. In the event of a breach, a backup will allow you to get up and running again quickly. Virtualization-specific backup tools and resources can help. Ensure that you’re can obtain point-in-time snapshots. This allows for fast file restoration should you lose data.

In addition, organizations should always remain ready to activate disaster recovery plans. For more on this topic, visit Globe Newswire.
