Let Vista, Win7 do not invade, more gorgeous

With the popularity of the Internet, viruses and Trojans and other malicious programs are spreading faster and faster. Once you are recruited, it is easy to cause system collapse or personal privacy disclosure. If the virus or Trojan is aimed at monetary interests, the harm will be even more serious, which may result in the loss of property. This problem exists in Windows 7 (hereafter referred to as Win7). Therefore, in order to ensure system security, it is particularly important to perform targeted security optimization on the system.

Note: For the convenience of operation, some of the texts are set up with the help of third-party software & ldquo; Rubik's Cube. You can download it from the official website of http://www.tweakcube.com.

First, Win7 system security settings Raiders

1, close the default shared blocking system backdoor

Like XP, Vista, Win7 also opens the network share by default ( As shown in Figure 1). Although this makes LAN sharing more convenient, it also creates conditions for virus transmission. Therefore, turning off the default share can greatly reduce the probability of the system being infected by a virus.

Open Rubik's Cube, click “System Optimization & Rarr; Network Sharing>, "Allow default management sharing and disk partition sharing", select “Save Settings” After restarting the computer, it is impossible to access the system through the default share (as shown in Figure 2). If you don't want to turn off all default shares at once, the cube also provides the ability to turn off a single default share. In the previous interface, select “default share"point"refresh", you can see the current system's default share list, select the default share that you don't need, click “Clear Share”, save the settings and restart the computer. The selected default share will be closed.

In addition, the Rubik's Cube also provides the "Restricted IPC$ remote default sharing", "and prohibits the inter-process communication IPC$ empty connection", which can effectively improve system security. The settings are recommended to be fully enabled.

2, modify the group policy Reinforce the system registry

The same as XP, Vista, Win7 still open a very risky remote access to the registry path. Setting the path to the remotely accessible registry to null can effectively prevent hackers from using the scanner to read Win7 system information and other information through the remote registry.

Open the Control Panel and select “Administrative Tools", double-click “Local Security Policy", turn on “Local Policies→Security Options", find on the right side<quo;Network Access: Remote access to the registry path & rdquo; & network access: remote access to the registry path and sub-paths, double-click to open, delete the registry path in the window (as shown in Figure 3).
