client to confirm each other before the application protocol transmits the First Data byte and negotiate an encryption algorithm and password key. During data transmission, the record protocol uses the key generated by the handshake protocol to encrypt and decrypt the data to be exchanged. SSL is independent from the application, so any application can enjoy its security without worrying about the execution details. SSL is placed between the transport layer and the application layer of the netw

verification, and information integrity. The SSL protocol consists of many sub-protocols, two of which are handshake protocol and record protocol. The handshake protocol allows the server and client to confirm each other before the application protocol transmits the First Data byte and negotiate an encryption algorithm and password key. During data transmission, the record protocol uses the key generated by the handshake protocol to encrypt and decrypt the data to be exchanged. SSL is independe

Key points and precautions for building openvpn for general enterprises in the centos Environment Briefly describe the enterprise environment. the ISP is connected to the Firewall of China-made hillstone network. The public IP address is 58. x. The firewall directly connects to the Huawei layer-3 Switch (core). The firewall's intranet interface IP address is 192.168.199.254, and the Management IP address of the layer-3 switch is 192.168.199.1, which b

event will be audited as an exception event, as it seems normal, since it is necessary to maintain a persistent connection, it should not be disconnected. Now it is disconnected, and that is not necessary. Second, for those environments where bandwidth is scarce resources, heartbeat packets occupy considerable resources, such as 3G users, without actual data transmission, the heartbeat packets sent will be completely wasted. Why does VPN need to maintain a persistent connection? Isn't it easy t

A few weeks ago, Canonical released the Ubuntu 14.04 LTS version. The new operating system has undergone great changes, but some problems still need to be solved, such as the openVPN import function. If you have used a VPN connection on Ubuntu, you should know that you have to download the network-manager-openvpn package from the official software package management center to achieve the VPN connection, it

The impact of the HeartBleed vulnerability on Heartbleed continues to expand. People thought last week that HeartBleed was only a nightmare for web servers, but over time, the threat of Heartbleed to enterprise intranet and data security is truly exposed, resulting in greater losses than web Services, and the repair is more difficult and long. According to Ars, researchers have recently completed the verification attack and successfully extracted the encrypted private key from the VPN Service R

Test the OpenVPN encrypted tunnel on a single machine and solve the problem In fact, the relationship between this article and OpenVPN is not very large, but the problems exposed during the OpenVPN test.
