Which Two Protocols Must be Allowed for an Ipsec VPN Tunnel is Operate Properly? (choose Two.)

Which protocols are used by IPsec choose two?

IPsec is a suite of protocols widely used to secure connections over the internet. The three main protocols comprising IPsec are: Authentication Header AH, Encapsulating Security Payload ESP, and Internet Key Exchange IKE.

What protocol does IPsec VPN use?

UDP, the User Datagram Protocol, does not set up these dedicated connections. IPsec uses UDP because this allows IPsec packets to get through firewalls. Decryption: At the other end of the communication, the packets are decrypted, and applications e.g. a browser can now use the delivered data.

What two protocols provide data authentication and integrity for IPsec choose two?

IPSec uses two distinct protocols, Authentication Header AH and Encapsulating Security Payload ESP, which are defined by the IETF. The AH protocol provides a mechanism for authentication only. AH provides data integrity, data origin authentication, and an optional replay protection service.

What are the two phases of an IPsec VPN?

VPN negotiations happen in two distinct phases: Phase 1 and Phase 2. The main purpose of Phase 1 is to set up a secure encrypted channel through which the two peers can negotiate Phase 2. When Phase 1 finishes successfully, the peers quickly move on to Phase 2 negotiations.

Which technique is necessary to ensure a private transfer of ...

Confidential and secure transfers of data with VPNs require data encryption.

Which two IPsec protocols are used to provide data integrity Choose 2?

IPSec provides confidentiality, integrity, authenticity, and replay protection through two new protocols. These protocols are called Authentication Header (AH) and Encapsulated Security Payload (ESP). AH provides authentication, integrity, and replay protection (but not confidentiality).

What are the two common data integrity algorithm used in IPsec?

Two main algorithms facilitate data integrity within the IPSec framework— MD5 and SHA1. HMAC guarantees the messages integrity. At the local end, the message and a shared secret key are sent through a hash algorithm, which produces a hash value.

What is an important characteristic of remote access VPNS?

A remote access VPN works by creating a virtual tunnel between an employees device and the companys network. This tunnel goes through the public internet but the data sent back and forth through it is protected by encryption and security protocols to help keep it private and secure.

Which feature of a VPN is designed to verify the integrity of data that has been transmitted over the network?

Authentication Header (AH) provides authentication and integrity to the datagrams passed between two systems.

What is a characteristic of an ASA site-to-site VPN? ASA site-to-site VPNs create a secure single-user-to-LAN connection. The IPsec protocol protects the data transmitted through the site-to-site tunnel.
