Effective management is the core of Intranet Security

Based on the current situation and problems of Intranet security, the technology alone cannot guarantee the competitiveness, or even the actual protection effect. These core causes of Intranet security problems can be solved only when the security management methods and security product management capabilities reach a certain level. In the face of increasingly complex application environments, administrators need tools with deeper, more refined, and higher intelligence to carry out their work. Otherwise, they will inevitably be drowned in the waves of security threats.

Universal Intranet Security Management System

Although many people may find it a cool thing to guard the target from hackers, in most cases, security management is a task built on standards and rigor. This requires not only correct application of security technology, but also preliminary planning and design, as well as later operation and support. Here, we will try to provide a basic model of the Intranet security management system. We hope it will be widely and long-term adaptive and cover the main problem domains of Intranet security.

Generally, an Intranet security solution starts from the formation to the formal operation. To identify the internal network security issues that need to be addressed or the internal network security issues, you must first form a requirement definition document. This requirement document should be evaluated by the Information Security Department and Administrative Department management personnel and then approved by a vote.

After that, the actual Intranet security protection system should be built based on the needs. Many Sub-steps can be carried out, such as the specific design of the security system. When an Intranet security system is evaluated, it will be integrated into the existing information infrastructure. Similarly, if the infrastructure changes, it should also be evaluated accordingly. After these tasks are completed, we need to evaluate and verify the formed security system to prove its effectiveness.

If there are no vulnerabilities and you are not careful, the Intranet security system will be put into operation in the actual working environment, subsequent adjustments to application environment changes, daily security management, and emergency response and support in case of security incidents will be carried out in an orderly manner.

Step-by-Step: How to manage intranet security

From the perspective of management goals, the main problem for Intranet security is the information in the Intranet, that is, Data. Although the application of Web, email, instant messaging, and business management systems in LAN and Internet has brought a lot of efficiency improvements to enterprises, however, not all people understand the risks that these applications bring to enterprise data, and do not know how to control these risks.

By classifying information and ing its potential security risks, and the possible losses arising when these security risks become a reality, security management personnel can develop effective control measures to reduce the risk to an acceptable level after having these basic materials. After the formation of a complete information classification system, organizations can begin to form their own basic security policies.

In addition to determining the status of protected assets, security policies are more important to define the extent to which information should be protected according to its level of risk. Under the guidance of the expected cost and target effect, security management personnel should choose the appropriate technologies and products to build security protection measures.

Of course, after everything is set up, many security management tasks need to be carried out repeatedly. However, it must be acknowledged that in many cases, security management personnel directly use building security facilities as the starting point of Intranet security management, at the same time, we will carry out subsequent work with low efficiency and blind posture. the most possible result is the formation of an internal network that may have security events. The following sample list shows how many beneficial elements are missing from the security work that begins without sufficient preparation.

In the 95% article about Intranet security management, the Intranet is used to represent the local network opposite to the Internet. However, in actual security management scenarios, the Intranet usually needs to be divided into different regions. Sometimes the network has been cut because of the needs of the organization's business, and sometimes it is to make the security system more hierarchical, therefore, data of different security levels can only flow in their own regions.

Many technologies can be used to isolate networks, such as firewall devices, relay gateways, application proxies, layer-3 switches, and VLANs. Although many enterprises use low-layer physical isolation devices to separate networks, the most widely used devices are still firewall devices. Another obvious trend is that most organizations use more than one technology or equipment to divide and manage network areas.

However, it would be inefficient to use these traditional and basic facilities for network isolation management, and it would be difficult to integrate with security management methods such as data isolation and application isolation. Therefore, a more respected approach is to integrate protection functions at various levels and in various directions under a unified management platform.

In addition, for computers that may cause damage to other nodes in the Intranet when a security problem occurs, the entire security management system can intelligently identify and cut it off from the Intranet. Such a system can simplify the burden on security administrators, and even every computer can be regarded as an Intranet in the Intranet. The management elasticity is evident.
