Comments: Network Security always Prevents viruses that are greater than passive viruses. many network administrators have come up with various ways to enhance network security control in order to resist the Internet virus. However, many of these methods do not require the h

amount of storage space, you can store the user's private key and digital certificates, the use of USB key built-in public key algorithm to achieve user identity authentication. Because the user's private key is stored in the password lock, it can not be read theoretically in any way, so the

base, the user's application level varies widely, if not effective protection, will produce a large number of discrete uncontrollable points, so that the entire network security out of control. An-day solution Antian Campus Network solution is based on the "unified Monitoring, distributed defense, effective corresponding, centralized management" as the guiding

Wi-Fi is inherently vulnerable to hacker attacks and eavesdropping. However, if you use the correct security measures, Wi-Fi can be safe. Unfortunately, the site is full of outdated advice and misunderstandings. Here are some of the things you should do and shouldn't do in Wi-Fi security. 　　1. Do not use WEP WEP (Wired Equivalent encryption protocol) security h

. At the same time, the firewall cannot protect attacks from internal networks and viruses. Therefore, the firewall protects the network passively. The attacked network does not know who initiated the attack on the network, and what method has been taken to achieve the attack purpose, I don't even know what measures should be taken to protect the

concern of internal networks. by using firewalls to divide internal networks, you can isolate key network segments on the Intranet, thus limiting the impact of local key or sensitive network security issues on the global network.In addition to

from eavesdropping. In the 802.11 standard, two encryption methods can ensure data transmission, namely WEP and WPA. WEP (Wired Equivalent Privacy ): Wired Equivalent confidentiality: A Shared Key RC4 encryption algorithm is used to ensure secure data transmission over wireless networks. The key length is initially 40 characters (5 characters ), later, it was increased to 128 characters (13 characters). So

Failure phenomenon: Windows security windows are often ejected when you connect to a wireless network, and you will need to resolve them after closing. Reason analysis: This problem appears in the WIN8, Win8.1 operating system, and most of the campus network users. This hint results from the 802.1X authentication turned on. The 802.1X protocol was de

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 wireless network. The WEP protocol encrypts data transmitted wirelessly between two devices to prevent illegal user eavesdropping or intrusion into the wireless network. However, the WEP

devices such as R2 need to use the R1 public key to encrypt data, R2 must make sure that this public key must belong to R1, instead of a public key belonging to a "villain", the most scientific way for R2 to determine whether the public key belongs to R1 is to check whether the public

. The default wireless LAN has absolutely no security at all, and almost all APS are configured to turn on WEP for encryption or use the default key provided by the original manufacturer. Because of the open access mode of WLAN, the hacker can enter the wireless network through its default password. Once the wireless LAN is connected to the enterprise, the hack
