NTP will await at least ten packets of information before trusting the time source.
And if the time source itself is attacked,the effects can be even more severe.
However, a network time server is only as good as the time source that it synchronises to.

Although the time source is free,the cost of a resulting attack on your network will add up.
One of the most problematic areas in synchronising a network is in the selection of the time source.
However, regardless of how trusted the time source is, there are two problems with internet time sources. .
Typically, NTP provides accuracies of between 1 and50 milliseconds depending on the time source and network paths.
Furthermore, malicious users can also attack the time source itself, which could also result in security problems.
Selecting the time source to use is perhaps the fundamentally most important thing in setting up a NTP network.
NTP is highly accurate andable to keep all machines on a network to within a few milliseconds of the time source.
Authentication is a set of encrypted keys that are used to establish if the time source is coming from where it is claiming to come from.
Meaning the time source may not be what it claims to be and with a hole in the firewall it could result in a malicious attack.
Whilst NTP can maintain synchronisation of a network to within a few milliseconds it is only as good as the time source it receives.
Coordinated Universal Time(UTC)is the time source that is most often used across the world to synchronise timekeeping devices.
Internet time sources can be affected by the distance of the client(the network) from the time source- it also can't be authenticated by NTP.
GPS NTP servers are designed to receive the time source generated by the atomic clocks onboard GPS satellites(Global Positioning System).
However, the key to NTP precision lies in the accuracy in the master time source, which in turn is reliant on where the time source comes from.
The time source used by the NTP time server is extremely important as this forms the basis of all time updates across the network.
NTP analyses it andconfirms whether it has come from the time source by verifying it against a set of trusted keys in its configuration files.
The time source is going to be distributed amongst all machines and devices on a network so it is vital that it is not only accurate but also stable and secure.
Latency over distance can create delays,which could lead to errors, and if the time source ever went down,the stock markets could hit trouble.
It works by using a single time source that it then distributes around the network, checking for drift, andcorrecting devices to ensure parity with the time source.
This makes them far more secure than internet providers as the time source is external to the network(and firewall) but also it makes them more accurate.
In this mode requests are sent by a client to a server,with the client expecting a response within milliseconds, unless the time source is unavailable or extremely busy.
Hackers and malicious users could tamper with the time source, leading to mayhem and cost millions and perhaps billions if the wrong time was spread around the exchanges.
However it must be noted that Network Time Protocol authentication,the security measure used by NTP to ensure the quality of the time source, is unavailable over the internet.
This poses a security risk,because not only can the time source get through this open network gateway to a network, but also they can provide access for malicious software to penetrate a network.
