In InterScan Web Security Virtual Appliance (IWSVA), the default maximum RSA key length (rsa_length) for HTTPS decryption is 2048 bits which may cause network and performance issues on protected computers.
This Hot Fix 1926 sets the default maximum RSA key length to 1024 bits and adds a hidden key to enable IWSVA to support changes to the "rsa_length" value.
Performing the manual steps is required.
To configure the "rsa_length" value:
- Install Hotfix 1926, which you need to request from Technical Support.
- Log on to IWSVA either directly or with Secure Shell (SSH) as administrator.
Run the following commands:
configure module https public-key length 2048 exit
To restore the default settings, run:
configure module https public-key length 1024 exit
