In the context of computer networking and cybersecurity, match the security protocols listed in List-I with their primary functions and architectural characteristics described in List-II.
- KerberosUses secret-key cryptography with ticket-granting tokens to authenticate client-server identities over insecure networks.
- IPsecOperates at the Network Layer (Layer 3) to authenticate and encrypt IP packets for secure Virtual Private Network (VPN) tunnels.
- PGP (Pretty Good Privacy)Combines symmetric and asymmetric key cryptography to provide privacy and digital signatures for email and file storage.
- RADIUSProvides centralized Authentication, Authorization, and Accounting (AAA) management for users connecting to network services.
Cevap
Kerberos matches with ticket-granting identity authentication over insecure networks; IPsec matches with Layer 3 Network Layer encryption for VPN tunnels; PGP matches with hybrid cryptography for email and file privacy; and RADIUS matches with centralized AAA network administration.
The correct mapping pairs each protocol with its exact operational domain: Kerberos provides ticket-granting authentication over non-secure networks, IPsec secures communications at the Network Layer (Layer 3) for VPNs, PGP provides end-to-end cryptographic security for emails and files, and RADIUS provides centralized Authentication, Authorization, and Accounting (AAA) management.
