I would like to disable weak cipher suite in SSH for over 100+ Firewalls with the following commands. The firewalls are running in High-Availability (H/A) mode, version 9.1.10:
set deviceconfig system ssh ciphers mgmt aes256-ctr
set deviceconfig system ssh ciphers mgmt aes256-gcm
set deviceconfig system ssh default-hostkey mgmt key-type ECDSA 256
set deviceconfig system ssh regenerate-hostkeys mgmt key-type ECDSA key-length 256
set deviceconfig system ssh mac mgmt hmac-sha2-256
set deviceconfig system ssh mac mgmt hmac-sha2-512
set deviceconfig system ssh kex mgmt ecdh-sha2-nistp521
set ssh service-restart mgmt
I would like to do this via script. However, when I look at PAN knowledgeable base, I see this:
The solution provided is not scalable in my environment. Is there a better way? How do Managed Service Providers (MSP) handle this with lot of PAN firewalls.
Hi @dtran ,
It is disappointing that these changes cannot be pushed from Panorama. However, you can push an SSH Service Profile and apply it to the management interface that effectively blocks those protocols.
With regard to the CLI, here is a similar (solved) thread -> https://live.paloaltonetworks.com/t5/general-topics/disable-weak-cipher-suites-for-ssl-tls-and-ssh/t....
Hi @dtran ,
Sure! This feature was introduced in 10.0. Create the profile under Device > Certificate Management > SSH Service Profile, and apply it under Device > Setup > Management > SSH Management Profile Setting. You configure what algorithms are allowed.
