Windows systems are far less secure than Linux or Mac systems, which is probably the most common argument. Is the security of the Windows system really so vulnerable? Not necessarily! With the release of Windows 7, the security situation will be further improved, and it is expected to get rid of the reputation of Windows system insecurity. It is understood that professionals also said: Windows 7 may or may not be the greatest operating system ever, but it is definitely the safest operating system ever. Why is this one?
1. Protecting the kernel The kernel is the core of the operating system, which makes it a major target for malware and other attacks. Basically, if an attacker can access or manipulate the kernel of an operating system, they can execute malicious code at a level that other applications and even the operating system itself cannot detect. Microsoft developed "kernel mode protection" to protect the core and ensure that unauthorized access does not occur.
In addition to protecting the kernel, Microsoft has made other fundamental improvements to protect the operating system after the launch of Windows XP. Many attacks are based on the attacker's ability to know the location of a particular function or command that resides in memory, or to perform an attack on files that may only contain data.
Address Space Layer Randomization (ASLR) allows attackers to block where they are attacking by randomly distributing critical operating system functions in memory. Microsoft has also developed Data Execution Prevention (DEP) to prevent files of any type that may contain data or files stored in the data area from executing any type of code.
2. Safer web browsing
Windows 7 comes with the latest and most powerful web browser version IE8. You can also download and run IE8 on other versions of the Windows operating system, so it is not specific to Windows 7, but it does bring some security improvements.
First of all, InPrivate browsing provides the ability to access the Internet privately, as revealed by the name private. When you launch an InPrivate browser window, IE does not save any information about your personal web surfing. This means that the information you enter is not stored in the cache, and there is no historical information to record the websites you have visited. This feature is especially useful when you are using IE8 on a shared or public computer (such as in a library).
Another security improvement in IE8 is the protection mode. The implementation of protected mode is based on the security components of Windows 7, which ensure that malicious or unauthorized code is not allowed to run on the browser. Protected mode prevents drive-by download attacks that allow users to install malware into your system when accessing a compromised website.
3.Protection, let us love and hate Things
User Account Control (UAC) is a model for all of us to love and hate on Windows Vista. UAC still exists when using Windows 7, but Microsoft has added a control slider that allows you to control the level of protection provided by UAC —— thus allowing the number of pop-ups to be accessed and executed The limit of quantity.
The pop-up window is just a small aspect that UAC can do to be seen. Under Windows Vista, many users simply disable all UACs, but that also turns off protected mode IE and some other operating system protection. The slider under Windows 7 is set to the same protection as Windows Vista by default, but you can customize it under the control panel.
