ESP requires both authentication and encryption. The transform set is negotiated during Phase 2 of the IPsec VPN connection process. Chapter 10 Exam Practice Final Exam Which statement accurately describes a characteristic of IPsec? or IPsec services allow for authentication, integrity, access control, and confidentiality. Integrity – IPsec ensures that data arrives unchanged at the destination using a hash algorithm, such as MD5 or SHA. Information required to establish the VPN must remain static. VPNs use logical connections to create public networks through the Internet. The purpose of the access list is to identify interesting traffic that should be sent encrypted over a VPN. ESP, which is protocol number 50, performs packet encryption. IPsec can secure a path between two network devices. Group Encrypted Transport VPN (GETVPN) uses a trusted group to eliminate point-to-point tunnels and their associated overlay routing. IKE uses several types of authentication, including username and password, one-time password, biometrics, pre-shared keys (PSKs), and digital certificates. Start studying Network Defense and Countermeasures Ch. A crypto ACL can define “interesting traffic” that is used to build a VPN, and forward that “interesting traffic” across the VPN to another VPN-enabled router. 14. What is the purpose of configuring multiple crypto ACLs when building a VPN connection between remote sites?
