Internet Protocols Questions
IPsec, or Internet Protocol Security, is a set of protocols and standards used to secure internet communications by providing authentication, integrity, and confidentiality. It is primarily used to protect IP packets transmitted over an IP network, ensuring that the data remains secure and private. IPsec operates at the network layer of the OSI model and can be implemented in both IPv4 and IPv6 networks. It offers various security services, including encryption, authentication, and key management, to protect against unauthorized access, data tampering, and eavesdropping. IPsec can be used for secure remote access, site-to-site VPN connections, and securing other network protocols.
