Your new (or even existing) wireless network is a broadcast radio station. Did you know that? Your Wi-Fi network works because it is a radio signal broadcast and received by all your wireless network devices. I would say that you never thought about it.
Instead of voice or music, you are broadcasting digital and zero.
And since this is a radio signal, as soon as it is broadcast, it just keeps moving. T travels behind your houses, behind your yard, bukhami and trees. It just keeps going, unlike ripples from a stone thrown into a pond, until it is blocked by some kind of obstacle or simply becomes weak. Until all of its energy is consumed, as it moves away from the transmitter, anyone who has a laptop PC or other wireless receiver with an external antenna can capture this signal. Even your neighbor with a laptop and the right piece of software can scan radio waves for broadcast signals.
So know that you see the reason why I argue that wireless security is so important. And there are two key areas in which safety is important:
Broadband security. All Internet connections are vulnerable to a hacker attack. It does not matter whether your connection is a fixed broadband connection or a dial-up connection. To protect your network from attacks, you must enable any available firewall. which is provided at your access point or router. A firewall is a term that is used on any device, hardware, or software that creates a barrier to access from the outside or from within your network. Very sophisticated firewalls are available, but only using the basic firewall of a NAT router can be effective.
Broadcast Security. As before, you transmit your network to the world. You can physically block your doors and windows of your home, giving your home to individuals. security. Buy, you cannot do this with transmitted wireless signals that penetrate the outside of your home. Therefore, you need to ensure the security of the overhead line, and this is called Wi-Fi Protected Access (WPA). There are several different WPA modes, and I have another article that discusses the differences and vulnerabilities of each of them.
I have two things about wireless security. Firstly, there is no such thing as a completely secure network security system that is 100% secure, secure and reliable. The second saying says that the best security system ever monitored is useless unless it is turned on. There are a number of articles that discuss various methods of protection, the advantages and disadvantages for each and how to implement them to make your network less attractive for external unauthorized access.
