Network access control to maintain Enterprise Network Security

From the perspective of the current network development trend, we can tell that in the future, enterprises will face serious network security threats, such as Trojans, viruses, and worms. At the same time, spyware attacks also speed up the spread. In order to better control enterprises' network access from undesirable devices or devices infected with malicious code, effectively control terminal devices that access network resources, and strengthen internal security control, protecting Enterprise data is an essential aspect of current security protection.

Notes for Administrators

In the face of the current situation of enterprise network security, as a network administrator of an enterprise, how can we manage how devices can be connected to the enterprise information system network to improve the level of enterprise IT Internal Control, security policy control is an important problem that enterprises face and need to solve. With the rapid development of the network, the number of external users is increasing, and enterprise management personnel are more difficult to control the terminal devices they use to log on to the enterprise network. Therefore, enterprises face a higher risk of malicious program intrusion.

Network Access Security Control is specially designed for the current IT internal control to ensure effective security control for all devices accessing network resources, to defend against the impact of various security threats on network resources and improve enterprise management and production efficiency. Make all access layer network devices in the network become a security enhancement point, and the terminal devices must meet certain security and policy conditions to access the network through routers and switches. In this way, the threats and impacts of worms and viruses on online businesses become more and more serious, so as to help customers discover, prevent and eliminate security threats.

Key Points of Enterprise Network Security

What is the architecture of the network access control solution? How does this solution implement factor detection? As factor detection is one of the main functions of network access control, it is very important to know how this solution can detect the elements of trying to enter the network in real time. If the network access solution does not support real-time factor detection, it is a problem whether the solution can protect devices that it does not know. The more external users there are, the greater the risk of network intrusion. On the one hand, enterprises must strengthen collaboration and resource sharing, balance risks in network security, and shoulder this major challenge.

If an enterprise uses this method for network access control, it can effectively block security vulnerabilities and prevent malicious programs from accessing the enterprise network through external user endpoints. Users can easily access network resources and take security control into account, so that enterprises can fully understand the network access status and the requirements for defending against threats, and provide secure and reliable network services, while sharing resources, it can also reduce the risk of network intrusion. Experts pointed out that to fully maintain the network security of enterprises, the following four aspects must be observed:

1. A complete network access control system should be developed based on the enterprise's purposes. A sound network access control system should include the policy system, organization system, technical system, and secure operation system.

Ii. overall consideration and unified planning. Network security depends on the weakest link in the system. "One breakthrough, a breakthrough across the network" means that a single system cannot effectively ensure security when considering security issues. Therefore, IT is necessary to establish a network security architecture at the overall IT system level to provide comprehensive protection.

Iii. centralized management and protection. Overall Design of the overall security architecture, establish a standardized and orderly security management process, and centrally manage security issues of various systems to avoid security "islands" and security "short board ".

4. Management is the core of enterprise network security, and technology is the guarantee of security management. Only when complete rules and regulations and codes of conduct are developed and reasonably combined with security technical means can the security of the network system be guaranteed to the greatest extent possible.

Three major issues of interest

Network access control is a summary of the above four aspects, but we still need to solve the following three problems through network access control technology:

I. terminal point security issues. Works with existing client security software and update management solutions to ensure that all client devices that can access the network have installed the latest definitions and policies to minimize the risk of malicious program intrusion. Promptly updates Network Vulnerabilities in the terminal system.

2. Enhanced Network Security Authentication coefficient: only designated devices and users can access specific enterprise resources. Enterprises can combine the existing identity authentication management architecture. Only the specified devices and users that have passed the verification can access specific enterprise resources to effectively reduce the risk of malicious program intrusion and confidential data leakage.

3. reduces the workload of enterprises for network security maintenance and increases cost-effectiveness. If enterprises adopt traditional anti-virus, firewall, and other network security methods, employees often encounter updates, software conflicts, management, and other problems, so that the IT support department is overwhelmed; once a virus or worm intrusion occurs, management personnel are even more exhausted. The network access control technology has advanced functions such as automatic detection and update, which can greatly reduce the need for user intervention, the IT support department does not need to spend a lot of time and effort every day to solve related management problems for users, but also to reduce the aftermath of enterprise network intrusion. The IT department reduces the support workload and can focus on more important work to improve the overall production efficiency of enterprises.
