Field Descriptions:

Subject:

  • Security ID [Type = SID]: SID of account that requested the “enable account” operation. Event Viewer automatically tries to resolve SIDs and show the account name. If the SID cannot be resolved, you will see the source data in the event.

Note  A security identifier (SID) is a unique value of variable length used to identify a trustee (security principal). Each account has a unique SID that is issued by an authority, such as an Active Directory domain controller, and stored in a security database. Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token for that user. The system uses the SID in the access token to identify the user in all subsequent interactions with Windows security. When a SID has been used as the unique identifier for a user or group, it cannot ever be used again to identify another user or group. For more information about SIDs, see Security identifiers.

  • Account Name [Type = UnicodeString]: the name of the account that requested the “enable account” operation.

  • Account Domain [Type = UnicodeString]: subject’s domain or computer name. Formats vary, and include the following:

    • Domain NETBIOS name example: CONTOSO

    • Lowercase full domain name: contoso.local

    • Uppercase full domain name: CONTOSO.LOCAL

    • For some well-known security principals, such as LOCAL SERVICE or ANONYMOUS LOGON, the value of this field is “NT AUTHORITY”.

    • For local user accounts, this field will contain the name of the computer or device that this account belongs to, for example: “Win81”.

  • Logon ID [Type = HexInt64]: hexadecimal value that can help you correlate this event with recent events that might contain the same Logon ID, for example, “4624: An account was successfully logged on.”

Target Account:

  • Security ID [Type = SID]: SID of account that was enabled. Event Viewer automatically tries to resolve SIDs and show the account name. If the SID cannot be resolved, you will see the source data in the event.

  • Account Name [Type = UnicodeString]: the name of the account that was enabled.

  • Account Domain [Type = UnicodeString]: target account’s domain or computer name. Formats vary, and include the following:

    • Domain NETBIOS name example: CONTOSO

    • Lowercase full domain name: contoso.local

    • Uppercase full domain name: CONTOSO.LOCAL

    • For local user accounts, this field will contain the name of the computer or device that this account belongs to, for example: “Win81”.

Security Monitoring Recommendations

For 4722(S): A user account was enabled.

Important  For this event, also see Appendix A: Security monitoring recommendations for many audit events.

  • If you have a high-value domain or local account for which you need to monitor every change, monitor all 4722 events with the “Target Account\Security ID” that corresponds to the account.

  • If you have domain or local accounts that should never be enabled, you can monitor all 4722 events with the “Target Account\Security ID” fields that correspond to the accounts.

  • We recommend monitoring all 4722 events for local accounts, because these accounts usually do not change often. This is especially relevant for critical servers, administrative workstations, and other high value assets.
