Windows7's "Deep Defense" concept

Microsoft's new operating system Windows 7 has been on sale for some time. Many users who are experiencing Windows 7 experience often encounter some annoying problems during installation and use. Some users even think that Windows 7 is as disappointing as the previous operating system. But is this really true? Especially on the issue of Windows 7 anti-virus concept, come with Xiaobian.

Microsoft said that Windows 7 is the safest Windows in history, but anti-virus vendors rebut, each said In the end, which is the truth? In fact, the truth may not exist, the news is sometimes only "angle" & quoquo; problem …

SophosLabs said last week that they installed Windows 7 on a bare metal and based on the user The account control (UAC) system is configured by default, but the anti-virus software is not installed, and then 10 virus samples are imported, and 8 viruses are found to be able to attack the Windows 7 vulnerability.

SophosLabs security consultant Chester Wisniewski said that UAC did intercept one of the virus samples. In any case, like his previous warning, Windows 7's UAC default configuration does not protect PCs from viruses. Windows 7 Not as secure as Microsoft claims. Wisniewski believes that Windows 7 is as disappointing as the previous operating system. But is this really true?

Yes, bad things happen.

First of all, as long as it is dangerous, you must be careful when executing the program. Although Microsoft's security director said: "If the user executes an unknown program on the computer, bad things will happen. ” But this has a dilemma: we buy a computer is to execute the program, is to download this download that is to play a variety of interesting things known to be unknown, that is, do not want to be restricted, do not want to be bound … … If we don't run as long as it is an unknown program, what fun is it to use a computer?

My opinion is: Users can "do their best" to do something to improve the problem, like ” The unclear program does not run it randomly, ” the company's computer, please use the rules ", & rdquo; the computer must be equipped with anti-virus software & rdquo;, one more effort to get one more guarantee, just like this . The current computer world is like a tropical rain forest, but it is full of poisonous snakes, arrow frogs and piranhas. It is better to save yourself than to complain.

The Microsoft Security Director believes that using a computer is a good way to execute a virus, and then that Windows 7 is not secure - this is too arbitrary. On this point, I have to say that I have really seen users indiscriminately pressing and arbitrarily executing a pass. It is useless to control your poison and no poison. Let's say it twice. So, this kind of testing by Shophos - although rudimentary, a little arbitrary - is not impossible. However, the Microsoft Security Director also agreed that Windows originally needed anti-virus software, and even Microsoft itself provided a free solution for users to use.

So, no matter what they are arguing, in the end, everyone remembers that the conclusion is right: running Windows must be equipped with anti-virus software - whether it is safer Windows. However, there is nothing to be disappointed with, and life is like this.

Windows 7's "Defense in Depth"

The Microsoft Security Director mentioned an interesting concept: the defense-in-depth concept, which is 啥?

This is the so-called "the principle of the siege defense”. You have to strengthen defenses from the inside out, in order to more effectively resist foreign enemies.

To keep the country safe, you have to build a city wall, a city pool, and set up a sentry outside the city to send patrol members. If possible, it is best to have people squatting and living outside the city. If so, even if there are foreign enemies. Intrusion (invasion of foreign enemies is unavoidable), and your defense will not be broken. Shophos believes that Windows 7 is not safer, and it seems to me to be " Windows 7 is still likely to be attacked by viruses", but this is actually a reasonable conclusion (Which city is always safe and will never be compromised? ).

And Microsoft's security director said that Windows 7 was compromised by the virus. "It was possible," Windows 7 originally needed anti-virus software. But Windows 7 does intensify every aspect of Windows, trying to make Windows 7 & rdquo; not so easy to be broken. He gave some links:

● UAC function

● Windows core protection

● Windows service enhancement (Windows Services)

● Random bit Address Space Arrangement (ASLR)

● Data Execution Prevention (DEP)

These things are very simple, that is, "trying to make Windows more stable from the inside out", this is "deep" Defense & rdquo;. Microsoft's security director wants to express: Some people say that Windows is invincible? No! So Windows needs anti-virus software can be said to be authentic! If you do not install anti-virus software is horrible! So, even Microsoft, also provides anti-virus software For customers!
