Cache encryption will be implemented to store encrypted data by default . This means that data in cache is stored encrypted by default providing data security without requiring entire drive encryption . BranchCache will be implemented to increase performance , manageability , scalability , and availability . Duplicate files are eliminated while hashes and local storage at branch offices drastically reduce the amount of required WAN traffic . Bitlocker encryption will be used to protect all user and server data . The benefit is that the entire drive is encrypted and only requires the user ‘ s normal authentication to access the data . The bitlocker system on the wired network will be set up to automatically unlock the system volume during boot to reduce the internal help desk calls because of lost PINs . Group policy settings will be enforced that require either Used Disk Space Only or Full Encryption is used when BitLocker is enabled on a drive . Groups : Users and computer accounts will be grouped to simplify administration by controlling permissions and rights rather than assigning them individually . Groups in Active Directory are objects that reside in the domain . Groups have a scope that identifies the extent that they are applied in the domain or forest . The three group scopes for WWTC are outlined below : Domain local scope is used to manage accounts within the domain . For example , a user group that requires access to a printer can be setup so
