AppLocker Definition and Setup Application Rules Enforce and Validate AppLocker Rules
27
AppLocker Default rules AppLocker Default rules Enables IT professionals to specify exactly what is allowed to run on user desktops Allows users to run the applications, installation programs, and scripts that they need to be productive Make sure key operating system files run for all users Make sure key operating system files run for all users Prevent non-administrator users from running programs installed in their user profile directory Can be recreated at anytime
28
TypeDescriptionMerge rule Hash Uses the file hash of a file If two path rules have the same paths, they are merged into a single rule. Path Uses a folder path or file path If two publisher rules have the exact same publisher and product fields, they are merged. Publisher Uses the attributes of a digitally signed file, like publisher or version No optimizations are possible because each hash is unique.
29
Enforcement In Local Security Policy, Configure Rule Enforcement area Refresh computers policy with gpupdate /force In Local Security Policy, Configure Rule Enforcement area Refresh computers policy with gpupdate /force OptionDescription Enforce rules, but allow setting to be overridden Default setting. If linked GPOs contain a different setting, that setting is used. If any rules are present in the corresponding rule collection, they are enforced. Enforce rulesRules are enforced. Audit only Rules are audited, but not enforced.

Overview Alert Levels Windows Defender Tasks
32
Three ways to help protect the computer: Definitions Three ways to help protect the computer: Definitions Used to determine if software that it detects is spyware or other potentially unwanted software, and then to alert you to potential risks. Works with Windows Update to automatically install new definitions as they are released. Set Windows Defender to check online for updated definitions before scanning.

Help you choose how to respond to spyware and potentially unwanted software Severe - remove this software immediately. High - remove this software immediately. Medium - review the alert details, consider blocking the software. Low - review the alert details to see if you trust the publisher. Severe - remove this software immediately. High - remove this software immediately. Medium - review the alert details, consider blocking the software. Low - review the alert details to see if you trust the publisher. Actions Quarantine – software is moved to another location on the computer; prevents the software from running until you choose to restore or remove it from the computer. Remove - permanently deletes the software from the computer. Allow - adds the software to the Windows Defender allowed list and allows it to run on the computer. Add software to the allowed list only if you trust the software and the software publisher.
