View source for IPsec

[[IPsec]] has three protocols Authenticated Header ([[AH]]), Encapsulating Security Payload ([[ESP]]), and IP Compression ([[IPComp]]).  In a short explanation [[AH]] adds a [[message authentication check]] to the header ensuring integrity of the payload.  [[ESP]] encrypts the payload following the [[IPsec]] header making it safer from [[sniffing]], and also adds a [[message authentication check]].
