- With the widespread use of networks and information systems, network and information system security issues have gradually become the focus of attention. Security measures of physical isolation are generally adopted between the confidential network and the Internet, which ensures the security of the internal network to a certain extent. At the same time, in a complex network environment, a confidential network is often composed of different operating systems, servers, firewalls, intrusion detection and many other security products. Once the network is attacked, professionals will extract logs from different log systems for analysis. The time of different systems is not calibrated in any way, which will unnecessarily increase the workload of log analysts. Therefore, the system should provide a unified timing source for the entire network time
-network clock server
-, unify the entire secret network server into a standard time, achieve time consistency of the audit system, and thus provide effective Intrusion detection and post-event tracing mechanism.
- The full name of the protocol is Network Time Protocol (
r
-). Its purpose is to deliver unified and standardized time on the international Internet. The specific implementation plan is to designate a clock source device on the network to provide timing services for computers in the network. Through this clock source product, many computers and network devices in the network can maintain time synchronization.
- This type of product produced by Jinan Weishang Electronics Co., Ltd. uses
- signals as the time source, and can also choose Beidou,
-,
-code and other time sources, embedded Internationally popular
- protocol synchronizes all computers, controllers and other equipment in the network to achieve network timing
,
- widely used in finance, communications, electric power, transportation, radio and television, security, Water conservancy, petrochemical, metallurgy, national defense, medical care, education, government agencies,
- and other fields.
- Network Clock Server
- Characteristics
-. High time accuracy, fast synchronization speed, and stable star collection.
-． High punctuality and accuracy. The internal timing unit of the device adopts advanced time and frequency measurement and control technology and intelligent taming algorithm. The crystal uses a high-precision constant temperature crystal oscillator, so that the timing accuracy of the device is better than
*-(
