Adictionary attackis a password-cracking method that systematically tries common words, phrases, and predictable passwords (e.g., "password123", "admin2024") to gain access to an account. Attackers often compile large lists of weak or reused passwords.

Phishingtricks users into revealing passwords but does not systematically test multiple words.

Credential stuffinguses breached passwords rather than guessing from a list.

Social engineeringmanipulates users but does not rely on automated password attempts.

Configuring RADIUS authenticationenhances Wi-Fi security by requiring user authentication before granting access to the network. This prevents unauthorized users from connecting and mitigates risks from rogue access points.

WEPis outdated and insecure; WPA2/WPA3 with RADIUS should be used instead.

A bus topologyis a network design choice, not a security measure.

Avoiding asymmetric encryptionweakens security rather than improving it.

TheNetwork layer(Layer 3 of the OSI model) includes theInternet Control Message Protocol (ICMP), which is used for network diagnostics (e.g.,pingcommand). ICMP helps in error reporting and network troubleshooting.

Transport layerhandles reliable data delivery (e.g., TCP, UDP).

Session layermanages communication sessions.

Application layerprovides end-user services.
