Management Solution SNMP is widely used in the monitoring and configuration of routers. SNMP Version 1 is not suitable for managing applications over the public network because of its low security. The access list allows only SNMP access from a specific workstation. This function can improve the security performance of the SNMP service. Configuration command: sn

improve application performance (some you don't even understand), and then focus on the browser network layer. Finally, there are some tips for browsers to improve the performance of Web applications.OverviewModern browsers are specifically designed for fast, efficient and secure data transmission for Web applications/websites. With hundreds of components running at various levels, from process management and sec
wireless routers have the wireless encryption function, which is an important protection measure for wireless routers. Data Encryption in radio waves ensures the security of transmitted data information. Generally, wireless routers and APs have the WEP encryption and WPA encryption functions. WEP generally includes 64-bit and 128-bit encryption types, you only need to enter 10 or 26 hexadecimal strings as the encryption password to protect the wirele
Digest is widely used. 3. Message Digest algorithm: it is a one-way hash function to prevent malicious tampering of packets. It is unidirectional and cannot be inferred from the message digest. 4. message authentication code (MAC): a function of message and key. 5. Widely used message digest algorithms: MD5 and Sha. Sha message digest is longer than MD5, but safer than MD5.Iv. identity authentication and key

Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus

WiFi access 1.1 Wireless Peer-to-peer Privacy WEP (Wired equivalent Privacy) WEP uses RC4 symmetric encryption at the link layer, and the user's encryption key must be the same as the AP's key to gain access to the network's resources, thereby preventing unauthorized users from listening and access by illegal users. WEP provides a 40-bit and 128-bit length key
