Description<\/span><\/h2>\n

IPsec VPN course. IPsec is a group of protocols used together to establish encrypted connections between devices. IPsec is often used to set up VPNs and works by encrypting IP packets, along with authenticating the source from which the packets came. In the term \u201cIPsec\u201d, \u201cIP\u201d stands for \u201cInternet Protocol\u201d and \u201csec\u201d means \u201csecure\u201d. Internet Protocol is the main routing protocol used on the Internet. Specifies where data will go using IP addresses. IPsec is secure because it adds encryption* and authentication to the process. In computing, Internet Protocol Security (IPsec) is a set of secure network protocols that authenticates and encrypts data packets to provide secure encrypted communication between two computers over an Internet Protocol network. Using IPsec:<\/span><\/p>\n

To encrypt application layer data and provide security for routers that send routing data across the public Internet.<\/span><\/p>\n

To provide authentication without encryption, you want to verify that the data originates from a known sender.<\/span><\/p>\n

It is encrypted to protect network data by setting up circuits using an IPsec tunnel where all data is sent between two endpoints, such as a virtual private network (VPN) connection.<\/span><\/p>\n

ESP is used to provide confidentiality, data origin authentication, connectionless integrity, an anti-playback service (a form of partial sequence integrity), and limited traffic flow confidentiality.<\/span><\/p>\n

Authentication Header (AH) is an IPsec protocol that provides data integrity, data origin authentication, and optional.<\/span><\/p>\n

Anti-broadcast services to IP. AH does not provide any data confidentiality (data encryption).<\/span><\/p>\n<\/div>\n
