Asus Network Management Switch creates a network security concept

For enterprises, information is undoubtedly the greatest wealth. With the proliferation of viruses and the prevalence of hackers, Enterprise Network Security Protection has received great attention. At first, people put more energy into improving the security protection performance of a single device and technology, people began to realize that enterprise switches, as backbone network devices, play a more important role in the deployment of enterprise network security protection. Using necessary security technologies on vswitches can not only effectively relieve the working pressure of other security devices, but also detect and solve problems in a timely manner.

For example, the anti-virus software seems powerless in the face of worms, the anti-search capability of the firewall is very weak, and the intrusion detection software cannot detect internal intrusion, and the switch can easily make up for the shortcomings of the above security devices. Nowadays, many enterprise users are also very optimistic about how to solve security problems through switches. Multi-layer switch features will become more and more common to improve network security.

It can be seen that the security and robustness of Enterprise switches directly affect the security and reliability of enterprise networks. Therefore, the security protection of Enterprise switches should be fully armed, in addition to having general exchange functions, it also provides the performance of professional security products. In terms of system security, switches implement security mechanisms in the overall architecture from the core to the edge of the network, that is, network management information is encrypted and controlled through specific technologies. In terms of access security, security access mechanisms are adopted, including 802.1x access verification, RADIUS/TACACST authentication, MAC address verification, and various types of virtual network technologies.

In addition, many vswitches also add hardware-based security modules. Some vswitches with Intranet security functions better curb the internal network security risks that flood with WLAN applications. The ASUS GX1116i +/1124i + Series 16-port and 24-port smart network management switches are widely used in the enterprise market, starting from network security and user business applications, it can implement specific security policies, restrict unauthorized access, and conduct post-event analysis to effectively ensure the normal development of enterprise users' network services. It has the following four technical measures to implement multi-faceted Protection for enterprise networks.

ASUS GigaX1116i +/GigaX1124i +

1. Support for 802.1x standards

First, the ASUS GX1116i +/1124i + switch supports the latest 802.1x Standard. As a security feature of LAN, 802.1x can force network users to log on to the network before accessing any devices and resources. This restricts access by illegal users to a large extent, so as to protect network security.

Ii. Traffic Control Technology

The ASUS GX1116i +/1124i + vswitch technology allows managers to easily control the bandwidth of each vswitch port and limit abnormal traffic flowing through the port to a certain extent, it can achieve storm control, Port Protection, and end security. It can effectively prevent DOS attacks while avoiding network congestion without affecting network performance.

Iii. Access Control List (ACL) Technology

The ACL technology controls inbound and outbound access to network resources. The switch can block or allow network access based on server and customer IP addresses. An ACL is a rule table. The switch executes these rules in sequence and processes each packet that enters the port. Each rule either allows or rejects data packets based on their attributes (such as the source address, destination address, and Protocol. Because the rules are processed in a certain order, the relative location of each rule is crucial to determining which packets are allowed and not allowed to pass through the network.

Therefore, the ASUS GX1116i +/1124i + switch with the ACL technology not only facilitates network managers to assign appropriate roles to them based on user needs, but also enhances network security shielding, hackers cannot find a specific host in the network for detection, and thus cannot launch attacks on Enterprise switches.

Iv. VLAN Technology

Virtual LAN is an essential function of a security switch and also a widely used security policy. A Virtual Local Area Network is an end-to-end logical network built using network management software on the basis of LAN switching. A VLAN can implement a limited broadcast domain on a L2 or L3 switch. It can cover multiple network devices and has nothing to do with their physical locations. The devices communicate with each other as if they were in the same network, in this way, enterprise network management becomes simple and intuitive.

Using the virtual LAN technology, ASUS GX1116i +/1124i + switches can divide users into several groups and only allow users to use the network resources they need. VLAN is divided based on the port VLAN, MAC address, and route access list, which limits unauthorized access between different VLANs, in addition, you can set the IP/MAC Address binding function to restrict unauthorized network access to improve the overall performance and security of the switched network. In addition, through VLAN creation, broadcast is isolated, and the broadcast range is reduced to control the generation of broadcast storms. For Networks Using VLAN technology, a VLAN can be divided into logical network segments based on Department functions, object groups, or applications.

Conclusion:

In fact, the enterprise network is like a person. It is certainly not enough to ensure the health of the human body to rely on regular medicines. Regular checks and good health habits are also required, and the security protection of enterprise networks is the same, neither method nor measure can be implemented. All aspects must be considered comprehensively. The security of the enterprise network from the Intranet to the Internet requires both firewall and other professional security devices, and the switch must play an active protection role to achieve multiple protection.

ASUS GX1116i +/1124i + vswitch is emerging with an increasing number of enterprise users taking a positive attitude towards consolidating network security through vswitches. It has professional anti-attack capabilities, is a complete and upgraded version of a common switch, with higher intelligence and security protection functions. I believe that the joint efforts of enterprise network security devices such as firewalls and enterprise switches will allow hackers to reject the virus!
