Article title: using IKE to build an enterprise virtual network (I ). Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. At present, there are two main risks facing internet communication: 1. information is peeked at or illegally modified during transmission; 2. illegal Internet access and attacks to the intranet. In

Two network cards mapped in Linux correspond to eth0 and eth1.The IKE a

In the previous article, the experimental environment was built. The protocol analysis can be performed once the IKE/IPSEC protocol is fully run and the relevant output and capture packets are collected. During the analysis, we will use the output of the IKE process and the Wireshark grab packet, combined with the relevant RFC, using Python to verify the calculation. First look at the full operation of the

When I first came into contact with IPSec, I was wondering why I had to negotiate for two phases? Negotiate an Ike SA first, and then negotiate an IPSec SA Based on the ike sa. Isn't it good to negotiate IPSec SA in one step? However, in practice, it is not so efficient to negotiate IPSec SA directly. For example, a company A has a subsidiary B. To facilitate its employees to access the internal data of Com

policy database that describes the policies that should be adopted for each IP datagram, namely passthrough, discard, or perform IPSec encryption and decryption. It also provides negotiation parameters for SA establishment, such as cipher suites and survival time. Newly generated SA is inserted into sad. Whenever a packet is sent or received, if the policy for it is IPSec, it is necessary to find the corresponding SA in the sad, according to the parameters provided in the SA, encrypt and decryp

Internet Key Exchange (IKE)Before exchanging data between two IPSec computers, a convention must be established first, a convention called a "security association", in which both parties need to agree on how to protect the information, exchange information, and other common security settings, and more importantly, there must be a way for the two computers to securely exchange a set of keys. For use in their connections. See figure Seven. Figure VII, I

Typically, files deleted on the local disk go to the system Recycle Bin, but if the system Recycle Bin is cleared (Shift+delete does not enter the Recycle Bin), it means permanent deletion. But just emptied the moment, and found that some of the files are very important, so at this time how should we do data recovery processing? ▲ emptying the Recycle Bin means permanently deleting it.
