Hackers are afraid that you will learn these 4 secrets.

1. WEP encryption cannot protect your wireless network. It's easy to hack in a few minutes, so you only get a false sense of security. Even an inexperienced hacker can break WEP encryption in a matter of minutes, making it useless as a protection mechanism. Many people have been using the router for many years, but don't even think about changing the password after a while and upgrading WEP to a more powerful and secure version of WPA2. Updating the router to WPA2 is a fairly simple process. To do this, you only need to follow the instructions that can be found on the official website.

2. Using the router's MAC filter to prevent unauthorized devices from joining is ineffective. Any IP hardware, whether it's a computer, a game, a printer, or anything else, has a unique MAC address in its network interface. Many routers allow you to allow or deny access to the network based on the MAC address of the device. The wireless router checks the MAC address of the network device requesting access and compares it to the list of banned and allowed addresses. This does sound like a good security mechanism, but the problem is that hackers can create a fake MAC address that matches the allowed LIST. All they have to do is use a wireless intercept program and see which MAC addresses bypass the network. They then set up a MAC address that matches the ONE that's allowed to enter the network.

3. Disabling the wireless router's remote administration feature can be a very effective measure to prevent hacking. Many routers have a setting that allows you to control them using a wireless connection. You get access to all router security settings and other features without having to access the computer that is connected to the router by cable. Although it is very convenient to be able to administer the router, this function opens an entry point for a hacker who can easily get to the security settings. In addition, many people never change the factory password on your router, thereby "help" the work of the hacker. Therefore, it is recommended to disable the remote control function so that only those with physical access to the network have access to the router settings.

4. If you use Hotspot for public use, you can easily become a target for a hacker attack. Hackers often use tools such as Firesheep or AirJack to get in the line of communication between the sender and the recipient during a conversation for which you are using a wireless connection. Once they get into your line of communication, they have the ability to retrieve your account passwords, read emails, and view messages. Also hackers use a tool such as SSLStrip, which allows you to access protected sites that you visit using your passwords. Therefore, it is advisable to use a VPN to protect your data if you are connected via Wi-Fi. Since VPN provides additional security, and it is very difficult to crack. If the hacker is not very persistent, he will most likely try only once and will move on to easier targets.
