 To get started, [download and run NM34_x64.exe](https://www.microsoft.com/download/details.aspx?id=4865). When you install Network Monitor, it installs its driver and hooks it to all the network adapters installed on the device.

+### Repair unsigned drivers
+
+Drivers that are not properly signed can block the upgrade process. Drivers might not be properly signed if you:
+- Disabled driver signature verification (highly not recommended).
+- A catalog file used to sign a driver is corrupt or missing.
+
+Catalog files are used to sign drivers. If a catalog file is corrupt or missing, the driver will appear to be unsigned, even though it should be signed. This can cause the upgrade process to fail. To restore the catalog file, reinstall the driver or copy the catalog file from another device. You might need to analyze another device to determine the catalog file that is associated with the unsigned driver.  All drivers should be signed to ensure the upgrade process works.
+
+To check your system for unsigned drivers:
+
+1. Click **Start**.
+2. Type **command**.
+3. Right-click **Command Prompt** and then left-click **Run as administrator**.
+4. If you are prompted by UAC, click **Yes**.
+5. Type **sigverif** and press ENTER. 
+6. The File Signature Verification tool will open. Click **Start**.
+
+    ![File Signature Verification](../images/sigverif.png)
+
+7. After the scanning process is complete, if you see **Your files have been scanned and verified as digitally signed** then you have no unsigned drivers. Otherwise, you will see **The following files have not been digitally signed** and a list will be provided with name, location, and version of all unsigned drivers.
+8. To view and save a log file, click **Advanced**, and then click **View Log**. Save the log file if desired.
+9. Locate drivers in the log file that are unsigned, write down the location and file names. Also write down the catalog that is associated to the driver if it is provided. If the name of a catalog file is not provided you might need to analyze another device that has the same driver with sigverif and sigcheck (described below).
+10. Download [sigcheck.zip](https://download.sysinternals.com/files/Sigcheck.zip) and extract the tool to a directory on your computer, for example: **C:\sigcheck**.
+
+    [Sigcheck](https://docs.microsoft.com/sysinternals/downloads/sigcheck) is a tool that you can download and use to review digital signature details of a file. To use sigcheck:
+
+11. In the command window, use the **cd** command to switch to the directory where you extracted sigcheck, for example **cd c:\sigcheck**.
+12. Using the list of unsigned drivers and their associated paths that you obtained from the File Signature Verification tool, run sigcheck to obtain details about the driver, including the catalog file used for signing. Type **sigcheck64 -i \<driver path\>** and press ENTER (or sigcheck -i for a 32 bit OS). See the following example:
+    ```

 ### <a href="" id="bkmk-impleconsiderations"></a>Implementation considerations
 
 Implementation of this policy setting is dependent on your operational environment. You should consider threat vectors, deployed operating systems, and deployed apps, for example:
+
 -   The likelihood of an account theft or a DoS attack is based on the security design for your systems and environment. You should set the account lockout threshold in consideration of the known and perceived risk of those threats.
+
 -   When negotiating encryption types between clients, servers, and domain controllers, the Kerberos protocol can automatically retry account sign-in attempts that count toward the threshold limits that you set in this policy setting. In environments where different versions of the operating system are deployed, encryption type negotiation increases.
+
 -   Not all apps that are used in your environment effectively manage how many times a user can attempt to sign-in. For instance, if a connection drops repeatedly when a user is running the app, all subsequent failed sign-in attempts count toward the account lockout threshold.

 This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
 
+> [!NOTE]
+> A lockout threshold policy will apply to both local member computer users and domain users, in order to allow mitigation of issues as described under "Vulnerability". The built-in Administrator account, however, whilst a highly privileged account, has a different risk profile and is excluded from this policy. This ensures there is no scenario where an administrator cannot sign in to remediate an issue. As an administrator, there are additional mitigation strategies available, such as a strong password. See also [Appendix D: Securing Built-In Administrator Accounts in Active Directory](https://docs.microsoft.com/windows-server/identity/ad-ds/plan/security-best-practices/appendix-d--securing-built-in-administrator-accounts-in-active-directory).
+
 ### Vulnerability
 
 Brute force password attacks can use automated methods to try millions of password combinations for any user account. The effectiveness of such attacks can be almost eliminated if you limit the number of failed sign-in attempts that can be performed.
 However, a DoS attack could be performed on a domain that has an account lockout threshold configured. An attacker could programmatically attempt a series of password attacks against all users in the organization. If the number of attempts is greater than the account lockout threshold, the attacker might be able to lock every account without needing any special privileges or being authenticated in the network.
 
-> **Note:** Offline password attacks are not countered by this policy setting.

 ### <a href="" id="bkmk-countermeasure"></a>Countermeasure
 
 Because vulnerabilities can exist when this value is configured and when it is not configured, two distinct countermeasures are defined. Organizations should weigh the choice between the two, based on their identified threats and the risks that they want to mitigate. The two countermeasure options are:
+
 -   Configure the **Account lockout threshold** setting to 0. This configuration ensures that accounts will not be locked, and it will prevent a DoS attack that intentionally attempts to lock accounts. This configuration also helps reduce Help Desk calls because users cannot accidentally lock themselves out of their accounts. Because it does not prevent a brute force attack, this configuration should be chosen only if both of the following criteria are explicitly met:
+
     -   The password policy setting requires all users to have complex passwords of 8 or more characters.
     -   A robust audit mechanism is in place to alert administrators when a series of failed sign-ins occur in the environment.
+    
 -   Configure the **Account lockout threshold** policy setting to a sufficiently high value to provide users with the ability to accidentally mistype their password several times before the account is locked, but ensure that a brute force password attack still locks the account.
 
     [Windows security baselines](https://docs.microsoft.com/windows/security/threat-protection/windows-security-baselines) recommend configuring a threshold of 10 invalid sign-in attempts, which prevents accidental account lockouts and reduces the number of Help Desk calls, but does not prevent a DoS attack.
+    
     Using this type of policy must be accompanied by a process to unlock locked accounts. It must be possible to implement this policy whenever it is needed to help mitigate massive lockouts caused by an attack on your systems.

-Generally, it is recommended that customers who are able to implement application control using WDAC rather than AppLocker do so.

AppLocker is a legacy technology which will continue to receive security fixes but will not undergo new feature improvements.

WDAC is undergoing continual improvements and will be getting added support from Microsoft management platforms. Although AppLocker will continue to receive security fixes, it will not undergo new feature improvements.
 
 In some cases, however, AppLocker may be the more appropriate technology for your organization. AppLocker is best when:
 
 - You have a mixed Windows operating system (OS) environment and need to apply the same policy controls to Windows 10 and earlier versions of the OS.
 - You need to apply different policies for different users or groups on shared computers.
+- You do not want to enforce application control on application files such as DLLs or drivers.
 
 AppLocker can also be deployed as a complement to WDAC to add user- or group-specific rules for shared device scenarios where it is important to prevent some users from running specific apps.
 As a best practice, you should enforce WDAC at the most restrictive level possible for your organization, and then you can use AppLocker to further fine-tune the restrictions.
