To disable 3DES cipher suites, select one of the following methods:
Method 1: Pulse Connect Secure 8.2R3 / Pulse Policy Secure 5.3R3 and above
Starting with 8.2R3 & 5.3R3 releases and above, granular cipher suites options were added. In these releases, administrator can manually select to enable / disable specific cipher suites and adjust the cipher suite ordering. Due to this, the administrator can manually remove the 3DES cipher suites options.
- Login to admin console
- Navigate to System > Configuration > Security > SSL Options > Inbound SSL Options
- Under Allowed Encryption Strength, select Show Selected Ciphers
- In the Selected Ciphers menu, remove all ciphers with 3DES
- Click Save Changes
In 8.2R8, all 3DES cipher suite options were removed from the Maximize Security (High Ciphers) option.
Method 2: Pulse Connect Secure 8.1RX / Pulse Policy Secure 5.1RX and below
Please upgrade to PCS 8.1R11.1 or PPS 5.1R11.1 and set the Allow Encryption Strength to Maximize Security (High Ciphers) option.
