Hi,
I was wondering what most folks use for NTP security?
Do they use the low cost, light weight symmetric key cryptographic protection method using MD5 or do folks go in for full digital signatures and X.509 certificates (AutoKey Security)?
I'm just wondering -- in globak scheme of security issue, is NTP security a major issue?
Just curious.
It's probably not a "major issue", but forged NTP data can, in theory, be used to allow the implementation of replay attacks. I'll admit I have never heard of a real-world case. -- R.
