NTP autokey auth or NTS on Palo

L0 Member

Hi Folks,

I am trying to secure the NTP on a customer Palo device (pa-220 currently running 9.0.12  and is being upgraded to 10.x.x in a week or so).   It current has options for auto-key and symmetrical key for authentication.   But from further reading auto-key is not secure (testing it to some public NTP servers like time@cloudflare show no sync) and I haven't found a public NTP server that will run symmetric keys.  As I understand it both are being replaced with NTS.  Is NTS available on Palo devices, or is my only option using symmetrical keys on a private NTP server?

Many Thanks

Hi @LeviMolloy ,

Unfortunately at this point your only options are autokey and symmetric key. Current versions (up to 10.2) are not supporting NTS
