Why ntp is important




















In systems that rely on ordered events occurring at specific times or logging of events, this can be a real problem. For instance, transactions generated by a computer with a system time slower than another computer may log a transaction as being received before the other computer even though it was generated after it.

Also wireless sensor networks need accurate time so that events can be logged correctly. A mechanism is required to disseminate accurate time around a network to computers and network devices in order to maintain order. It provided complex algorithms to maintain a high degree of time synchronization of computers on a network. Time clients obtain highly precise timing information from a time server in order to calibrate their own internal system time.

Routine backups are critical to any business. However, systems that are way out of sync may fail to back up correctly, or even at all. This could result in the loss of valuable data and leave your system exposed to hackers. Installation of an NTP time server, such as the NTS GPS server supplied by Galleon Systems, means you would never have to worry about missing a scheduled data backup for your computer network again.

Network Accelerators, and similar devices, use caching systems which could rely substantially on file time stamps to figure out which version of data is the most current. Poor time synchronisation can cause such devices to stop working properly and use incorrect versions of data. When errors occur across your computer network, using information stored in system logs is an essential part of diagnosing a fault.

However, if the timing for these logs is not in sync the process of identifying a fault will take much longer, leading to delays in getting a system working again. In the event of a network security breach, identifying how your network was compromised and how your data was infiltrated may only be possible if you have accurate, time-stamped server and router logs.

Hackers will delete logs where they can, however, when they are unable to the job will be far more difficult.

If time data is inaccurate, hackers are presented with much more time to exploit your network and inflict greater damage.

Purchase of an NTP time server, such as the NTS GPS server supplied by Galleon Systems, would prevent this problem meaning you never have to worry about being unable to track security breaches again. This is similar to your stove or microwave losing power and the clock resetting after a power outage.

What makes this problem even more troubling is drift. Modern computer clocks are not perfect—they will slowly deviate from the proper time by seconds, or even minutes, per month.

If the system has been running for a long time without the clock being reset, the deviations can be compounded. When multiple devices are in usage, without time synchronization, each resource will think the correct time is different. If you try to compare logs between resources, none of the timestamps line up. If the data is aggregated to a log server or security information event manager, the events will appear jumbled, and analytics and correlation engines will not be able to process the data for unusual behavior or indicators of compromise.

This becomes a security nightmare and a formidable challenge for any cyber forensics investigations. Some savvy threat actors may even tamper with NTP, knowing that it will complicate forensic log analysis and make their actions and tracks harder to uncover amidst the data noise. Good security starts with good timing. Good timing implies that all resources in an environment—from cameras to servers—all have the correct time. In order to set the correct time, the most common method is to use an NTP server—but not every device needs to be an NTP client.

When GPS is used the internal clock accuracy is less than 50 nanoseconds. Its protocol cannot be changed or re-configured to obtain timestamps from a different time server when the primary time server is down. Hence it is also called a short NTP version of client software.

The NTP- Network Time Protocol uses built-in algorithms to configure, obtain and distribute network time with an accuracy of 0. Its algorithm is amenable to being configured to get timestamps from an alternate time server in case the original server is out of synchronization or fails. For this one need not run the NIX computer but rather one uses the NTP client software for synchronization of the time server. Modern versions of time servers like Symmetricom, use NTP software which provides Domain Time II software for monitoring, management and time client synchronization.

Conclusion In conclusion, the accuracy, security, ease of use and reliability of the dedicated network time server is very important to what is NTP and the NTP time server. Request callback.
