We randomly seem to get some alerts that say:
SYSTEM ALERT : high : error: Key exchange failed in SSH handshake - DH key
I'm new to Palo Alto firewalls and was just curious if this is something that can be ignored? Was thinking that this might be the result of just some networking issue this to fail and generate this alert.
It seems that this alert was generated because of a failed attempt to gain access to the device via SSH. If you think, someone is trying to get unauthorized access on your device, you may configure "permitted IP Addresses" list on your PAN firewall.
Hope this helps.
