How to protect information security.

The most common such as the IPSec protocol. Ipsec There are three modes, one must be mandatory, and the other is the recipient requested, and the third is not used. When a host A to host B to send data files, the host A and B will host the first consultation, including the need to adopt technologies on IPSec packet is encrypted. The first is to be used, that is to say, whether the host A or B host must support IPSec, otherwise, the transmission will end in failure. Second, we request the use of such consultations in the process, ask the host A host B, the need for using IPSec. If the answer does not need to adopt the host B, then use an express delivery, unless the A’s host IPSec policy settings that must be made mandatory. If the answer is that the host B can be encrypted IPSec, A host of the first packet will be encrypted and then sent. After the technical IPSec encrypted data, the general has been very difficult to break. Moreover, it is important that the encryption and decryption of the work for the user, is transparent. In other words, we need to configure the network administrator of IPSec good strategy, no additional staff movements. Whether or not to use IPSec encryption, will not be adopted to achieve any results, and so on, staff will be among the hosts for their own consultations, without the need for our additional control.
