Digital signature troubleshooting

About this task

Each time you open AppScan, it verifies the digital signature of its security rules (DLL file). Verification can fail for several reasons:
  • DLL file is corrupted
  • DLL file was tampered with (possibly by a hacker)
  • The following certificate, which is installed by default as part of the Windows installation, is missing from the list of "Trusted Root Certification Authorities" certificates in the Windows store:
    VeriSign Class 3 Public Primary Certification Authority - G5

Procedure

  1. Make sure you have the following root certificate installed: 
    VeriSign Class 3 Public Primary Certification Authority - G5
  2. Uninstall and re-install AppScan.
  3. If these steps do not solve the problem, contact Support.
    Note: The warning message gives you the option of continuing if you are sure your system has not been compromised.
