This article describes how to enhance the security of a Cisco router by using a Nipper. So how should we use it? The following article gives you a detailed answer. How do I use a Nipper? Since Nipper supports so many devices and is also known to support a wide range of multi-functional options, it is impossible for me to present them in all aspects. However, we can make a basic demonstration. In our example

Cisco held a network lecture entitled "define your router with 256 or fewer bytes". The subject of this lecture is: "the accuracy and performance improvement of network security products forces hackers to successfully launch attacks in the first 256 bytes of the Code, so that they can easily intrude into the network without being noticed ". As a result, Cisco dev

We have explained a lot about the configurations of CISCO switches. Here we will mainly explain the port security configurations of CISCO 3550 switches. Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for s

Improving system security involves many aspects, one of the important steps is to turn off unnecessary services. Although Microsoft Windows XP is not a network operating system, the default is that many of its services are open. For a sober Microsoft user, shutting down some unwanted services is an important aspect of security. Of course, each version of Windows offers a different service, so services that

not encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA.8. We recommend that you use FTP instead of TFTP for iOS upgrade and backup and configuration file backup. For example:Router (config) # ip ftp Username blushinRouter (config) # ip ftp password 4tppa55w0rdRouter # copy startup-config ftp:9. Upgrade
