You can read the data, but you cannot modify it. It does not encrypt the data, so it does not provide confidentiality. ESP does not provide integrity for the IP header (addressing).Īuthentication Header (AH) provides authentication, integrity, and anti-replay for the whole packet (both the IP header and the data carried in the packet).
Ordinarily, only the data is protected, not the IP header. ESP does not ordinarily sign the whole packet unless the packet is being tunneled.
Transport mode - In transport mode, only the payload of the message is encrypted. A volume named WatchGuard Mobile VPN is created on your desktop.There are two modes of operation for IPSec:
You cannot switch the group during the negotiation.Ī larger group results in more entropy and therefore a key that is harder to break. If mismatched groups are specified on each peer, negotiation does not succeed. Group 1 provides 768 bits of keying material, and Group 2 provides 1,024 bits. Group 2 (medium) is stronger than Group 1 (low). Mobile VPN with SSL or IPsec) to use LoginTC for the most secure two-factor authentication. The LoginTC RADIUS Connector enables the WatchGuard XTM and Firebox VPN (e.g. The strength of any key derived depends in part on the strength of the Diffie-Hellman group on which the prime numbers are based. The LoginTC RADIUS Connector is a complete two-factor authentication virtual machine packaged to run within your corporate network. Diffie-Hellman Mediumĭiffie-Hellman groups determine the length of the base prime numbers that are used during the key exchange. Secure Hash Algorithm 1 (SHA1), with a 160-bit key, provides data integrity. 3DES processes each block three times, using a unique key each time. 3DES is the most secure of the DES combinations, and has a bit slower performance. Data Encryption Standardĭata Encryption Standard (3DES) provides confidentiality. These values are hard-coded in the client and you cannot change them.
