If necessary, block all ports except for business needs, and isolate non-working and illegal users from internal network resources as much as possible to strictly prevent illegal intrusion technically, ensures the security of internal

Microsoft has announced a strategic partnership with 360 of the world's largest Internet security company to upgrade the win 10 operating system free of charge to 96.1% of Chinese users. After win 10, 360 will be distributed to Chinese users for free to upgrade win 10, to help Chinese users first time experience win 10 of innovative technology. 360 is Microsoft win 10 's only security partner. It is

based on the actual running status of the adjacent network, make the best effort to transmit data packets at the optimal route and minimum cost. Whether or not a router runs securely and stably directly affects Internet activities. Whatever the cause, the router crashes, the denial of service, or the operation efficiency decreases sharply, the results will be disastrous. Router Security Analysis The

Many IT security executives use a variety of security solutions, but often do not communicate effectively with each other and hinder effective defenses, which is then analyzed by Trend Micro.Profiling attacksA complete threat defense platform should cover four elements across the entire life cycle of a threat:Prevention : Assess vulnerabilities and potential threats and proactively protect endpoints, server

lot of network names, which are the service settings identifier (SSID). The default SSID is typically associated with the router's brand. For example, if you buy Tp-link, your SSID must begin with Tp-link. A hacker can easily know your router brand through your SSID. You can change the SSID to a name you like in a line-free management interface, at least to some extent to conceal your wireless route. Modifying the SSID is the easiest way to do it, an

Turn off the UDP 123 port to protect against certain worm viruses. ③ Close the UDP1900 port: In the Control Panel, double-click management tools → services to stop SSDP Discovery service. Turn off this

operation of the business system, and so on. (3) Knowledge "island". Many cutting-edge security technologies are often only understood by a few people within the enterprise, and they lack the means to share these knowledge to improve the overall security level of the enterprise. At present, the security field is becoming larger and smaller, and the experts in

As we all know, in windows, when Apache is installed as a service for the first time, it will run with the user "System" (Local System account. If all the resources of the web server are on the local system, this will have fewer problems, but it will have a lot of security permissions to affect the local machine, therefore, you must never enable the network permissions of the System account! Create a new ac

Wireless network technology is growing, but how can we use encryption protocols to ensure the security of wireless networks? This shows us how to set security. With the increasing maturity of wireless communication technology, the price of wireless communication products is falling, and wireless LAN is gradually entering thousands of households. However, wireless

Its built-in wired peer-to-peer Security WEP protocol is a common method for user authentication and data encryption. WEP encapsulation technology can disrupt data before transmission, and then use an algorithm named sh
