This document is not actually a career planning, but a classification description. The only benefit is to help you understand the skill requirements of different positions, because you have been busy recently, this article is far from reaching the details of the body of knowledge. We plan to add another real career roadmap when we are idle.

reception. As long as malicious users have certain knowledge about wireless networks, the security of enterprise wireless networks is quite a problem. Intruders can destroy and intrude through highly sensitive receiving devices.

We will only include one sentence: "WEP provides comprehensive security for wireless LAN from data security and integrity to data source authenticity, but the WEP Key is easy to be obtained by attackers ". Although the vendor has been strengthened to address this issue, Microsoft also released the related upgrade packages (KB826942,

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
spending a lot of money. The key is the right setting.
The goal of each security management plan is to make the intrusion process more complex, require more time, and be caught in a higher probability to guard against potential intruders or attackers. Even if you are installing fences in your yard, lock the door, keep a dog in the yard, put a latch on the window and the door, install the burglar, and you
methods to protect the security of the wireless LAN, there is also a more effective protection method, that is, to encrypt the wireless transmission signal, this method often has a high security protection effect.
Currently, there are two common encryption methods for wireless node devices: WEP encryption and WPA encryption. Among them, WEP technology is also called Peer-to-Peer
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.

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 Unfortunately, the site is full of outdated advice and misunderstandings.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.
