Windows 7 Security Enhancements - BranchCache
(Page 4 of 4 )
DirectAccess is great for the mobile worker, but what about the remote worker who works out in a branch office location? One thing all branch offices seem to have in common is limited network bandwidth. Accessing large files in a branch office is always a slow, frustrating affair. Most users prefer a snappy network and quick downloads.
Windows 7 incorporates BranchCache, another technology that works in conjunction with Windows Server 2008 R2, which helps make network responsiveness of applications and data housed within a user’s data center feel snappy. This gives users in remote, branch offices the experience of working as if they were on the local area network (LAN) of the server they are accessing.
BranchCache also helps reduce the utilization of the wide area network (WAN). When BranchCache is enabled, a copy of any data accessed from Intranet Web sites and/or file servers is cached locally within the branch office. When another client on the same network requests the file, the client downloads it from the local cache without downloading the same content across the WAN.
As mentioned previously, aside from discussing Active Firewall Policies, DirectAccess, and BranchCache, Cooke also discusses BitLocker To Go, and AppLocker in his Windows Security Blog. BitLocker To Go, which is an extension to BitLocker in Vista, allows users to encrypt the disk volume of removable storage devices with a password and/or a digital certificate stored on a smart card. The program will also share data with Vista and XP users via a read-on program called BitLocker To Go Reader.
Additionally, Cooke said that Windows 7 will give control back to IT pros with AppLocker, which is a feature that helps them eliminate unknown and unwanted software from their network environment -- such as user-installed P2P programs, unnecessary games, unlicensed software, etc. AppLocker also allows end-users to install and run approved applications and software updates based upon their business needs.
Technical talk can seem quite overwhelming, especially for the average Window’s user, but just know this: these security enhancements are going to make your PC safer and your life easier. What more could you ask for?
