Windows Patch Notes for CTE v7.5.0

Resolved Issues

Known Issues

• AGT-36370: The vorvmd.log reports an error message when guarding LDT over CIFS GuardPoint

  This error message displays when the CTE agent is in the process of authenticating the user. This error can be safely ignored.

• AGT-39189 | AGT-55063: CTE failed to unguard after changing to incorrect CIFS credentials

  If a user has a CIFS guarded path, and tries to access it with invalid credentials, the unguard request fails. After this, if the user switches to valid credentials, the unguard request still fails because CTE agent is unable to access the CIFS share to update the credentials.

  Work-around

  To successfully guard/unguard a CIFS path, use valid credentials.

• AGT-39190: File modified time does not change after rekey for excluded files

  This is a limitation with the current CTE agent. This is due to the Windows Redirected Drive Buffering Subsystem (rdbss) limitation.

• AGT-48196: Microsoft DPM recovery creation failed when creating an incremental backup recovery point

  Work-around

  Perform a complete backup. Do not perform an incremental backup.

• AGT-48580: gzip files in a directory can be mistakenly identified as ransomware by Ransomware Protection

  Some compression algorithms haves high entropy value and intermittently, zip or unzip activity that occurs within a ransomware GuardPoint is identified as ransomware.

  Work-around

  Add the zip/gzip/winzip programs to the Ransomware Protection process exemption list in the CipherTrust Manager.

• AGT-48862: Unguard process fails if CTE secfsd service is down

  secfsd service is a critical CTE service. If this service is down, certain CTE features may not work as intended.

  Work-around

  Manually restart the secfsd service in the service manager.

• AGT-58577: Issues and limitations for Multifactor Authentication and Ransomware Protection co-existence

  Multifactor Authentication is not yet supported for a GuardPoint with Ransomware Protection with a CTE Agent.

• AGT-61138: When applying a GuardPoint on the UNC (Universal Naming Convention) name instead of a Local drive, files display as cipher-text format when accessing using local drive

  User must apply GuardPoint on the local drive. If the user decides to apply the GuardPoint on the UNC path, user must use the UNC path to access the data. Do not view through the local Windows explorer path.

• AGT-61679 [CS1581483]: The Apache service does not start when launched within a GuardPoint

  This issue is interoperability issue between CTE and Windows Defender.

  Work-around

  Create an exclusion rule for Windows Defender that will exclude the Apache2.4 directory.

• AGT-61846: In a Windows Access Only node with LDT over CIFS, the Access-Only Node becomes inactive after agent is rebooted

  CipherTrust Manager fails to push the CIFS credentials to the Access-Only node. This issue will be fixed in the upcoming CipherTrust Manager release.

  Work-around

  Unguard all affected clients and then re-guard them on CipherTrust Manager.
