Win7's powerful security protection makes it streaking and secure

With VISTA's path, Microsoft gradually realized the real needs of users - easy to use, stable, secure, and efficient, so there is a new generation of Microsoft's peak The work - Windows 7. Security protection makes Windows 7 gradually accepted by users, and more and more people have already adopted Windows 7 as their preferred operating system. Some people even boasted that the use of Win 7 does not need to install kill soft, "streaking" can "can swim" Internet. "Niu Ren", this is a rumor, I believe it is not without any basis, then what is the security protection of Win 7? Is it really like "Niu Ren", using Win 7 can "streaking"?

Perhaps the answer is yes, Win 7 security protection system, mainly consists of a complete protection system, including internal and external firewall, Windows Defender (malware scanning tool), IE 8, user account control, data execution Protection and so on. And they are not their own camps, but under the unified scheduling of the “Operation Center”, they form a mutual protection against system security.

Security first barrier ——system firewall

In the era of Windows XP (hereafter referred to as Win XP), many friends compare its firewall because it can only be used Station connection for screening, for Trojans with bounce ports, it is easy to penetrate it, the protection effect is not satisfactory. Even when installing some soft kills, you will be prompted to turn off the system firewall, which shows that its function is weak. In Win 7, in addition to the original "Windows Firewall", also added a "Advanced Security Windows Firewall". For the sake of narration, here we will refer to “Advanced Security Windows Firewall” as “Advanced Firewall”.

Windows Firewall provides primary protection

Win 7 does not abandon the traditional "Windows Firewall", but compared with Win XP, it has more control over private networks and public networks ( Please refer to the Advanced Firewall section). By default, Windows Firewall allows all outbound connections while blocking all inbound connections. To allow a program to make an inbound connection, just check it. This setup is simple, but it is very effective for filtering inbound connections, because it is only a small number of programs that users need when blocking all inbound connections. “Green light”, control is in the user In your own hands. In addition, if a program is still in the blocking state, Windows Firewall will automatically pop up a dialog window when the program is running, prompting the user to take permission or rejection, so as to avoid affecting normal work.

Therefore, Windows Firewall is both effective and convenient in blocking inbound connections. Generally suitable for environments with less high security requirements, mainly for the general user community.

Open the Control Panel and click on “Windows Firewall & Rarr; Allow Programs or Features to Pass Windows Firewall” to open the settings interface. By default, the items we choose are grayed out (not available), you must click “change settings” to modify the options below. This is actually a process of privilege escalation, because there is no permission to modify the settings before clicking it. When clicked, the user account control dialog box will pop up. At this time, you must click “yes> to change, otherwise it cannot be performed. . It is estimated that everyone has encountered anti-virus software, the firewall is shut down by malicious programs, and the use of user account control is actually a barrier, if the user does not actively promote the permissions, it can not be changed, malware does not work.

At the same time, in order to simplify the operation, user account control is also divided into four levels. In the highest level 1 state, changing the settings will pop up the user account control dialog; at the second and third levels (from top to bottom), no dialog pops up, but user account control still works; at level 4 It can be modified directly (not recommended).
