6. Context and Importance :- Wi-Fi networks are essential for connectivity but pose security risks. Cybercriminals exploit vulnerabilities to access data, disrupt services, and compromise privacy. Strong Wi-Fi security is vital to safeguard personal information and prevent unauthorized access to network resources. Problem Definition :- Protection of Personal Information: Personal data sent over unsecured networks is vulnerable to interception by malicious actors, potentially resulting in identity theft and financial harm. Network Integrity: Unauthorized network access can result in congestion, decreased performance, and enable malicious activities such as malware distribution. Compliance: Many industries, such as healthcare and finance, are obligated to maintain high levels of network security to safeguard sensitive data, as mandated by regulations like HIPAA and financial standards, to mitigate the risk of unauthorized access or data breaches. Wi-Fi security is vital for several reasons:-

7. Unauthorized Access : Wi-Fi networks can be easily accessed by attackers if default settings or weak passwords are used. Strong passwords and customized configurations are crucial to prevent unauthorized entry. Weak Security Protocols : Outdated security protocols like WEP and weak implementations of WPA are still prevalent in many networks, making them vulnerable to attacks like packet sniffing and brute force attacks. While modern protocols like WPA3 provide better security, they are not widely adopted. Upgrading to the latest security protocols is essential to mitigate these risks. Password Strength : A strong Wi-Fi password is vital to prevent unauthorized access. Weak passwords are vulnerable to guessing or cracking, emphasizing the importance of using strong, complex passwords for network security. Handshake Vulnerabilities : During the handshake process, which establishes connections between devices and networks, vulnerabilities can be exploited. Attackers may intercept and decrypt data, potentially leading to data breaches and unauthorized access. Device Management: Monitoring and managing all devices connected to a network is vital for security. Unknown or unauthorized devices could indicate a breach, highlighting the importance of effective device management for securing network access. Disconnecting Unauthorized Devices: It's vital to be able to disconnect unauthorized devices from the network to uphold security and integrity. Without this ability, networks remain vulnerable to ongoing exploitation by unauthorized users.
