With the development of China's routing industry, its market demand is also increasing. As a leader in the routing industry, Cisco routers have a very high market share. Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk

With the development of China's routing industry, its application is also more extensive, especially the application of routers and firewalls. Here we mainly explain the security configuration of NetEye firewall and Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that Cisco routers already exist in the ne

Maybe many people do not know the actual application of the NetEye firewall and the Cisco router. Next we mainly analyze the security problems of the NetEye firewall and the Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that there are already routers in the network and some simple packet filtering funct

The following is a brief analysis of the port security function of a Cisco switch. It is taken from the recently published Cisco/H3C switch advanced configuration and management technical manual. The Port security function in the Cisco IOS switch limits the number of MAC add

This article describes in detail the basic introduction to the access security of CISCO Router network devices, and introduces basic security logon, terminal protection, authorization, and other issues, I believe that reading this article will help you. To protect their Cisco networks, many administrators are busy with

To protect their Cisco networks, many administrators are busy with what traffic can be allowed to pass through network devices, and how to restrict the unique information exchanged between mail route upgrades and other routers. The access control list (ACLs) usually solves these problems quite simply. The security of network devices is important to any networked environment. To solve this problem,

AES encryption. This product may support 802.1X along with the EAP-TLS, or other EAP types. Therefore, WPA2 provides more powerful identification and Data Encryption than LEAP. However, selecting an EAP protocol and WPA2 protocol should be left to consumers for decision. Therefore, security is ultimately related to configuration. How to make a decision depends on your WLAN. However, most WLANs that use the WPA2 Protocol use more powerful EAP-type pro

A malicious user may use a Sniffer tool like Sniffer to perform local monitoring on the Administrator host or an appropriate interface to obtain the Administrator's password for logging on to the Cisoc router. So how can we use SSH to enhance the remote management of Cisco routers? 1. Security Testing I installed sniffer locally and used Telnet to log on to the Cisco
