I am having trouble finding how to prefer CTR ciphers for SSH over the weaker CBC Mode ciphers. Currently I only see AES-128, AES-192 and AES-256 available in ScreenOS. Are CTR ciphers available with ScreenOS version 6.3.0r26 or r27? I did find a KB article on Juniper support that speaks more to the fixes in JunOS for CTR ciphers and it has a statement saying "Note that ScreenOS is not vulnerable to this". The CVE is CVE-2008-5161. ANy help would be greatly appreciated.
Additionally can someone point me to what the End of Support dates for the ISG-1000 and ISG-2000 as well as the End of Support dates for 6.3 software?
Thank You
