Protecting Wireless Networks against Rampant Threats

Short Description:

Wireless Networks need to be protected. There are different methods of protection such as setting new passwords, modifying the SSID setup, performing encryption, setting firewalls, ensuring financial security, and also setting the HTTPS option. The PE Exam Prep Course helps you to learn about Wireless Communication.

A lot of important data are floating over the network. If it is a wireless network, the threat is even more. As engineers, we need to be very cautious and protect the data on Wireless Networks.

The following points can be noted to protect Wireless Networks:

The password provided by the System administrator is for short term use. It is important that you maintain the highest security by renewing your alphanumerical password on a regular base.

Your wireless network should not make it public to other networks. The Service Set Identifier (SSID) must be switched off. This ensures that your wireless network does not announce its presence. The PE Exam deals with wireless communication.

The manufacturer would have given an SSID name. This manufacturer’s SSID name is the default and has to be changed. This is because anyone can guess the manufacturer’s SSID name. Encrypted data have been always safe. You have to make sure that the wireless data is encrypted using WPA or WEP encryption. WPA is more secure than WEP. So, it is advisable to go in for WPA encryption. The network should be protected against malware. The anti-malware protection must be installed on all devices. The automatic malware protection update must be set right on all devices. Wireless Communication is an important topic of PE Exam Prep.

Safety of Wireless Public Networks

Always make sure that the Firewall is ON. When you are on a public network, certain unscrupulous elements may try to attack your network. The Firewall will protect you against such unsolicited attacks. When you buy wireless devices, usually it is shipped with the Firewall option turned off. Before you start using the device, make sure you turn the firewall ON. Never update your software directly from the network. Always opt for automatic updates.

Have a protected network, even if you have to pay for access. Passwords, credit card numbers, and other important financial information must not be spread on the internet. When you are not using the wireless networks, you should remove the external Wi-Fi card. If the Wi-Fi card is internal, use the software to disable the wireless network.

In your browser, always choose the HTTPS option. You can also use a Virtual Private Network (VPN). So, even though you are on a public network, you are routed through the safety of the private network. A filter for the MAC address should be setup. The PE Prep course deals with all aspects of Wireless Communication such as Wi-Fi.

You need to be cautious when using your Wi-Fi in public areas. You can reduce this shoulder surfing by being careful about who is standing near you while you operate your Wi-Fi. Always make sure that your communication is safe and you are in a position to watch what is happening with your devices. The PE Exam Prep Course covers the Wireless Communication as a part of the Telecommunication topic.
