On the one hand, network security is ensured by encryption. The following describes common wireless network encryption methods. Through the introduction of these encryption methods, you can learn how to set up security and what security vulnerabilities are. Although the name

Content Security Policy According to the requirements of the Content Security Policy, Microsoft is obligated to provide users with protection measures against cross-site scripting and Click-Jacking attacks. Another company, Mozilla, has begun deploying this mechanism

unauthorized access points for network access, which is very dangerous. Fortunately, most enterprises scan access point settings to avoid the emergence of illegal access points. For individual users, measures such as tracking and interception should be taken to prevent the use of illegal access points. 4.

WirelessNetworkSecurityAlthough the name seems to be a security option for wired networks, this is not the case. The WEP standard has been created in the early stages of wireless networks and is designed to become a necessary security protection layer for WLAN in Wireless LAN. However, the performance of WEP is undoubt

For wireless wi-fi security, encryption technology must be emphasized to affect network security. Recently, the security of Wireless WiFi has attracted wide attention from all walks of life. Hackers use free WiFi bait to defraud users of trust and steal users' personal information, how to protect the

For netizens, a variety of potential threats may come at any time. In these threats, often is "Ming gun good hide, stabbed difficult to prevent", network virus, hacker tools we pay more attention, the loss is relatively few, but for the use of special means to spy on personal privacy, but have overlooked. Clearly has caused the privacy of the leak, but no knowledge. Therefore, what kind of measures to ensur

Now you know how to implement account security and have established an effective authentication mechanism. Next, we will implement access control in security. Access control must be implemented locally and remotely. Files can be accessed locally or remotely over the network. This course will test the two methods one by one.Windows NT File System SecurityWhen crea

It seems that most of the Windows enhancement suggestions will help you ensure Windows security in the NT domain name or Active Directory. How can we ensure the security of P2P Windows networks? There are many networks that use Windows workstations without central servers. This type of network is common in Small departments of small enterprises or large enterpris

However, with the development of E-commerce and personal

Network equipment is also an important device in the network boundary. It is the main road to the entire data center and cannot cause any loss. In the past two days, the Nexus network equipment was reinforced with simple security measures, the main operations are summarized as follows: 1. Create

with an HMAC. HMAC is formed in this way: first, a data structure is established, which includes Alice's temporary value, Bob's temporary value, their identification, and shared secret key KAB; then hash the data structure and the hash result is HMAC. When Alice received message 2, she now had the identity of Ra, Rb, both sides, and secret key KAB, so she could also calculate HMAC. if the calculated HMAC is the same as the HMAC in the message, she k
