AppLocker in Windows® 7
What are the uses and features of AppLocker in Windows 7?
The AppLocker is a new feature in Windows 7 that improves the features and functionality of Software limit Policies. It contains new facilities and extensions that lets you create rules to allow or deny applications based on unique identities of files and specifies which users or groups run those applications. With the help of AppLocker applications, the user can control the executable files, scripts, Windows Installer files and DLL files. The rules are defined based on file attributes derived from the digital signature like the publisher, product name, file name, and file version. It helps to allocate a rule to a security group or an individual user. It creates exceptions to rules. The user can create a rule that lets all Windows processes to run except Registry Editor. It enables you to use audit-only mode to use the policy and understand its impact before enforcing it. AppLocker is perfect for organizations that presently use Group Policy to manage their Windows-based computers. As AppLocker is an additional Group Policy mechanism, the administrators must have experience with Group Policy creation and operation.
Following are the different uses and features of AppLocker in Windows 7:
- Easy to administer
- Rule based structures
- Import and export rules
Easy to administer
Windows 7 provides new application control policies with AppLocker. Applocker is flexible and easy-to-use mechanism that enables IT professionals to state what is allowed to run on user desktops exactly. It limits unauthorized software while allowing applications, installation programs, and scripts that the user need. With this, IT professionals can realize the security, operational, and compliance benefits of application consistency.
Rule based structures
The AppLocker provides simple and powerful rule-based structures for identifying which all applications can run that are centrally managed using Group Policy. It provides 'publisher rules' that is based on application's digital signature by making it possible to construct strong rules that account for application updates. With properly structured rules, the IT professionals can deploy updates to the allowed applications without setting up a new rule for each version update.
The import and export rule of AppLocker affects the entire policy. For example if you export a policy then all the rules from all the rule collections are exported including the enforcement settings for the rule collections. If the user imports a policy, all the criteria in the existing policy are overwritten. The AppLocker in Windows 7 helps to decrease the administrative overhead and organization's cost of managing computing resources by lessening the number of help desk calls that result from users running unapproved applications.
