Network perimeter security: Managing endpoint security

With network access expanding from the office to the home and even local coffee shops, securing the network perimeter is among a security admin's top concerns. In preparing for the myriad threats that come with remote access, however, it can be easier to secure traditional network perimeter endpoints, like laptops, desktop computers and removable storage devices. Check out these tips for securing your network endpoints.

These days, it seems like the majority of network perimeter security concerns are related to telecommuters, remote access and VPNs. Hardening these areas is clearly of great concern as the mobile workforce serves as a treasure chest for clever hackers if they can take advantage of an unsuspecting remote user.

But what about physical endpoint security like laptops, desktops and removable storage devices? Just because these types of hardware might represent a more traditional network perimeter, physical endpoint security is no less important today than it ever was. If a hacker finds a way to get his hands on a laptop that has important files from your network on it, you could be facing disaster. Learn about endpoint security best practices by checking out the tips below.
