Analyze the following credentials in WLAN, point out their advantages and disadvantages
meaning
WI-FI PROTECTED SETUP (WPS)
feature that allows the owner of Wi-Fi privileges to block other users from using their household Wi-Fi and also allow other users to use the Wi-Fi.
advantages
WI-FI PROTECTED SETUP (WPS)
- Simplify wireless connection just using a push button, or PIN, QR, NFC.
- key is randomly generated and less predictable minimizing the risk of network intrusion while the
disadvantages
WI-FI PROTECTED SETUP (WPS)
- an attacker within radio range can brute-force the WPS PIN for a vulnerable access point.
- Anyone that physically can access the push button can connect
advantages
Biometric
- Biometric authentication is an effective way to secure digital devices and data.
- It provides a higher level of security and convenience than traditional authentication methods because fingerprint, retina, voice, facial recognition are unique
disadvantages
Biometric
- its disadvantages false positives, and high costs.
- Privacy concerns the biometric information stored in third party application.
advantages
OTP (one time password)
- Safe from Replay Attacks: OTPs provide security against replay attacks, as each password is valid for a single use only.
- Convenience: OTPs leverage the ubiquity of mobile phones and SMS functionality, making them convenient for users.
disadvantages
OTP (one time password)
- Risk of Account Lockout: Loss or theft of the OTP device can lead to the risk of multiple login attempts, potentially resulting in permanent account lockout.
- a potential the OTP token can be leaked and use by attackers because the validity time.
- Costs for Providers: OTP providers, especially those offering hardware devices such OTP server and Telecommunication SMS charges.
meaning
WPA/WPA2
Personal are security protocol designed to secure wireless computer networks.
advantages
WPA/WPA2
- It provides strong encryption and easy to manage making it suitable for home users.
- It can be used and setup easily cost effective in SOHO enterprises. Small office and home office.
disadvantages
WPA/WPA2
anyone with the passphrase can access the network that makes it lacks individual user authentication and may have limitations in protecting against insider attacks if user’s credentials are compromised
advantages
digital certificate
- strong encryption and authentication and are difficult to forge or compromise, thus preventing common attacks that exploit weak or shared passwords.
- easily deployable and manageable across large networks without requiring users to remember or enter passwords.
disadvantages
digital certificate
- Setting up and maintaining the necessary infrastructure, such as a CA, certificate server, and database, can be costly and difficult, particularly for small or medium-sized networks.
- Users may need to install or accept certificates on their devices or enroll or register with the network, which can be confusing or cause errors.
