Wireless networks have transformed the way we communicate by enabling information transmission over long distances without the need for cables, increasing convenience and efficiency. However, ensuring the security of transmitted data is a major concern. Despite the technology's immediacy and convenience, it remains vulnerable to attacks, particularly in the case of Wi-Fi. To gain an in-depth understanding of wireless network security, it is advisable to read an article that covers the mechanisms and protocols used in these communication systems.

Security mechanisms in wireless networks

Wireless networks are equipped with various security protocols that ensure the confidentiality of transmitted information and offer competitive solutions compared to wired alternatives. However, these protocols can be complex, and a lack of knowledge among administrators and users can leave systems unprotected. Cybercriminals often target 802.11 networks due to their wide coverage, which allows them to carry out undetected attacks from any location. Thankfully, several security measures are available in wireless networks to safeguard our information.

• Make the wireless network invisible. This is achieved by disabling the SSID, therefore the device will not appear on the available networks. You just have to activate the configuration dedicated to Wi-Fi and enter the name of the network manually.
• Use WPA2-PSK AES encryption. This option is much more secure than the previous one and consists of hiding the SSID and using a stronger password.
• Change passwords. Another simple and easy alternative to carry out is to change the password that the router offers us by default.

Taking these details into account, fiber optics for companies is very successful in terms of security. Ethernet cables are made of copper and carry information via electrical current. This measure is much more vulnerable and exposed to information leakage. Whereas fiber optic uses light and is much more immune to interference.

Security protocols in wireless networks

When it comes to wireless networks, security is a major concern. To meet users' security needs, WPA (Wi-Fi Protected Access) or Wi-Fi-protected access are considered the preferred options. On the other hand, WEP (Wired Equivalent Privacy) is no longer reliable due to its weaknesses.

WPA offers several security features, such as dynamic distribution of keys, the use of initialization vectors for better confidentiality, and robust authentication and integrity techniques. It can operate in two modes: the AAA server or the initial shared key (PSK). The AAA server mode requires a configured server for authorization tasks, while the PSK mode is ideal for home users or smaller networks.
