Question:Most firewalls or UTM deployment modes include the routing mode, the bridge mode, and the hybrid mode. The core configuration is the write rule, A good rule will greatly improve the security of the internal network. Of course, if UTM is used, other security components may be attached. For example, the most common rule is the AV anti-virus component, IPS components, anti-spam components, and some ot

SSL is a security protocol, and data is encrypted throughout the transmission process. In addition, because the SSL gateway isolates the Intranet server and the client, leaving only one Web browsing interface, most trojans on the cli

In the United States, open source technology has infiltrated many enterprises, for IT staff, the impact of open source has been expanding. But in China, corporate users ' awareness of open source remains largely Linux. Open source Email Security Gateway, open source intrusion detection, open source vulnerability analysis, open source

The advantage of these VPNs is that they do not need to install any clients on the connection endpoint, and they are easy to install and configure when accessing common applications.

Virtual Private Network (VPN) refers to the technology for establishing a private network on a public network. It is called virtual network, mainly because the connection between any two nodes of the VPN network does not have the end-to-end physical link required by the traditional private network, but is built on the network platform provided by the public n
, it can fully control the host of the other party and is also a concern of many hackers. Therefore, I do not recommend using this solution in an insecure environment. For example, it can be used over the Internet. If you want to use the Internet, it is best to use vpn and other relatively safe connections. VPN uses the security tunnel technology, which not only

A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server in DMZ (or in its own network segment) to handle wireless connection, VPN gateway requirements, and firewall information, and enable or disable the wireles
