Wireless LAN security skills
The development of wireless LAN is very rapid, but like wired LAN, security also needs to be considered. Otherwise, it may cause problems such as file leakage and hacker attacks.
1. Security Check
Whether you are using public wireless hotspots or just connecting to a home or company network, you need to use some basic principles to protect your wireless connection:
(1) Activate MAC address verification at the Access Point and modify the default MAC address ID and password;
(2) Enable 128-bit encryption;
(3) Enable 802.11 encryption;
(4) install and correctly configure the personal firewall to ensure that information such as credit card numbers, bank accounts, and email addresses are not disclosed without permission;
(5) install anti-virus software;
(6) If you need to access the company, home, or campus network, you also need to install a virtual private network outside the personal firewall. If you use a laptop to work, you need to access the company network through public wireless hotspots, request the network administrator to establish a network connection for you.
2. Network Administrator principles
(1) keep in mind that wireless networks are working. It is not as simple as it sounds. Unauthorized access points installed by employees or hackers can convert a wired network into a wireless network without your knowledge;
(2) to ensure that your company has established a sound security policy, all employees must be clear about the provisions and strictly enforce them. Specify precautions for wireless networks, and implement standard chemical engineering for devices used by the network to ensure the latest security patches and Upgrade Procedures;
(3) to install a virtual private network on a wireless network, it is best to take other security measures, such as security tokens and digital certificates. By using a wireless network as a remote access method for your network and integrating it into your network security layer, You can provide both employees and partners with secure and remote access;
(4) try to reflect in a specific direction, and the full-line Antenna broadcast to the surrounding area of 360 degrees is more vulnerable to attacks;
(5) establish an intrusion detection system in your overall security solution;
(6) consider the wireless LAN as insecure as the Internet, and take corresponding security measures.
