Meticulous Intranet security management to ensure Network Security

Intranet SecurityFor enterprises, the problem should start from four levels and take into account the internal network security of the enterprise comprehensively. In terms of it o & M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security. In response to the above problems, access security, desktop security, behavior security, and configuration security in it o & M management must be well managed over the Intranet, enterprises should adopt a set of strict O & M security software to control the security legitimacy of all network participants in the intranet.

First gate access security

To maximize the security of the Intranet, enterprises should first clarify the identity of Intranet users. It is not uncommon to have cases of Intranet security accidents caused by illegal access to the Intranet. Therefore, IT department administrators should also begin with security identity authentication to ensure the legality of Intranet users. We recommend that you manage the access security in two ways. First, the administrator should plan and allocate the Intranet IP addresses and strengthen the control over IP Address resources. For example, if a fixed user allocates a certain number of IP addresses and reserves some IP addresses for temporary access users, and sets permissions for temporary access users to access the specified network within a specified period of time, this effectively improves the utilization of IP resources and the security level of the Intranet.

Another aspect is to further emphasize the registration of legitimate IP address users, because although the Intranet matches the IP address and the device, the user may not necessarily abide by the IP address rules, that is, the IP address may be tampered with without authorization, or use other devices illegally. In this case, prevention is also required. Through O & M management software, management personnel can set relevant rules. When someone illegally occupies others' IP addresses and sends an alarm, they can identify illegal terminals and take network disconnection measures, this effectively avoids the internal network disorder caused by preemptible IP resources.

Second gate Desktop Security

Desktop is the activity place for Intranet participants. Therefore, standardizing the use of terminal desktops becomes another important responsibility of administrators. In specific operations, administrators can implement these four aspects: control the security use area, assist the security operation enhancement, statistical analysis of security events, and use of security regulations. First, the Intranet needs to determine the accessible range for different users, that is, to control their accessible regions. For example, a business personnel can legally access the ERP system and INTERNET resources, but cannot access the financial system. User-level division standardizes the scope of use of the entire network, effectively eliminating the occurrence of illegal access events.

Second, administrators often need to take some auxiliary measures to enhance the security of the operation, mainly refers to the detection of terminal system vulnerabilities, software vulnerabilities, environmental vulnerabilities at all times, once a new vulnerability is generated, immediately download the latest patch file for installation within the entire intranet, improving the security level of the Intranet terminal device. Again, the security statistics analysis function, compare and analyze historical records of Intranet security problems, so as to summarize possible security risks in the Intranet, and adopt a solution to solve the problems at one time. Finally, implement security level specifications, with a series of security level settings, management personnel can view the security status of all equipment on the network in real time, thus eliminating Security blind spots, it has played a positive role in guiding the improvement of Enterprise Intranet security levels.

Third gate behavior Security

As the name suggests, we have strictly confirmed the legality of terminals and the legality of user identities. Further, we need to standardize users' operation behavior so as to ensure Intranet security. The Administrator analyzes the security analysis modes preset by the management software and uses data stream analysis tools at three levels: IP abnormal frame traffic, IP scan capture, and IP address scanning port, it can intelligently identify abnormal data flow behaviors in the Intranet, analyze the data source, and locate the terminal device, so that the administrator can take direct measures to cut off the network of the abnormal device and resume the normal operation of the Intranet.

Fourth gate Configuration Management

An important condition for the normal operation of the Intranet system is the configuration parameters of the device. You also need to pay attention to this aspect of Intranet security management. In general, the management software automatically backs up the configuration parameters of network devices and host devices in the Intranet system, monitors the configuration parameters in real time, and sends an alarm when there is a parameter change, the management personnel can restore the device configuration based on the backup configuration parameters to ensure the normal operation of all the devices on the Intranet, and also provide support for the operation of the entire intranet system on the hardware platform.

The above four aspects can be described as interlocking and in-depth. enterprise IT departments use management software to perform security management in strict accordance with the above four steps, which will certainly increase the Intranet security level and minimize the probability of Intranet security accidents, truly becomes the "patron saint" of enterprise network security ".

Intranet security issues have gradually become a topic of concern to enterprises. Once a security problem occurs in the enterprise's network system, the impact may be fatal. Therefore, enterprises should pay attention to it.
