What Is Wi-Fi Security? WEP, WPA, WPA2 & WPA3 Differences
Wi-Fi security refers to the protection of Wi-Fi networks and connected devices from unauthorized access, data breaches, hacking, and other potential cyber threats. It involves implementing security measures, such as encryption, authentication, and security protocols, to protect the data that is transmitted in a wireless network, its users / devices and the network infrastructure that it is connected to. Wi-Fi security protocols like Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, and WPA3 are designed to provide different levels of security. For instance, WEP is the oldest and least secure, while WPA3 is the latest and most secure protocol.
What Is a Wireless Intrusion Detection System (WIDS)?
A wireless intrusion detection system (WIDS) is a security solution specifically designed to detect anomalous activities, intrusion attempts, and vulnerabilities within a wireless network. It can identify possible attacks, unauthorized access, or misconfigurations in the network. WIDS accomplishes this by monitoring radio frequencies for specific packet patterns or behavior associated with malicious activities. It plays a crucial role in enforcing network security policies and protecting against threats such as rogue access points, identifying weak encryption methods, and weak or default passwords for pre-shared key authentication mechanisms.
What Is Network Security? Types & Importance Explained
Network security encompasses a wide range of technologies, procedures, and protocols strategically crafted to safeguard the integrity, confidentiality, and availability of computer networks and the associated data. This involves implementing measures to prevent and monitor unauthorized access, misuse, alteration, or denial of the network and its resources. Network administrators typically achieve this through a combination of hardware devices, such as routers and firewalls, and software programs, such as antimalware tools. Techniques used in network security include data backup, encryption, user authentication, intrusion detection systems, and continuous network monitoring.
