With the continuous development of computer technology and network technology, the computer has become our work, learning, and a tool that cannot be lacking in life. Computer networks have gradually become a communication means of our work, learning, and life. Then we face a new problem - computer security issues. A problem that makes many computer experts' headaches. However, when you encounter unfortunate, have you ever thought that you are not only a victim, you may be playing the role of the disabled. Do you want to be a victim's attack target? Don't you want to be a destroyer? So, you will start from yourself, ask yourself: "Is my computer safe?", Check your own or under the following mistakes:
1, password error practice:
A, password is not safe:
Users always like to choose easily (often is easy to crack) password. For example, Test, Password, the name of the full fight, 1234567, etc. These passwords often have the same virtual, more excessive, and we have many colleagues do not have a password. I used to download a tool for guessing passwords from the Internet, and just scanned the computer in the company's network, the user in the administrator group (including the local administrator account and domain account) and the empty password Some people in the "virtual" password. If I am a hacker, or a safe, I can do whatever you want, copy files, delete files, and even format the entire hard drive; I can also build "base" for attacking the entire network on these computers. These machines have become an attacker who is commanded.
B, share passwords between several users:
Especially when multiple users share a computer, the user usually shares a password. This is extremely unsafe. In one, the password is easy to teach, both, when there is a problem, the problem is not found in the problem. So, in the company's network, for the environment of the shared computer, we recommend the computer to join the domain, then assign the right to limit the different domain accounts.
C, use the password of the internal website on the external website
If you accidentally disclose your password to the person outside the unit, then they are easy to guess the company's related information through your other information, such as domain names. In this way, they can take an attack on other users of the company. So, please use the external website (for example, an external forum, etc.), using a password different from the company's internal account.
2, ignoring the update and patch provided by the software provider, especially the security patches of the operating system
Any software and hardware will have security vulnerabilities and will be in a constantly evolved state. Before the software is lost, it is usually continually issued, improved the design and correcting the update of the error. And some colleagues are often troubles, do not want to install these updates, especially the operating system update, and regret when their own virus is invaded or hacker attacks.
3, workstation is open, no one is worth
In many colleagues I have touched, few people will lock the computer when they leave their own computers. This is actually open to the door of your own home, then there is no difference. At this time, anyone can use your identity to operate your computer on your machine. So, if you want to leave your computer, please press "Ctrl Alt Del" three keys to lock your computer.
4, disabled and less existing security control, especially anti-virus control
The company adopts the enterprise version of antiviral software and other measures to monitor our system in real time. However, some users tend to get faster processing speeds, do everything possible to disable them to expose their computer in danger.
5, install unnecessary or unlicensed software
I think any normal person will not put a bomb to my pillow. So, please don't easily install unnecessary or unwanted software. If you installed a software, it happens to be a hacker program, then you have buried a "bomb" that will blow up the entire network at any time. 6, unnecessary exposure too much personal information
Tell others that your child's name, detailed date of birth, etc. will provide attackers to provide more opportunities to guess passwords or unauthorized access through social engineering methods. So please don't provide too much personal information to people you are not familiar.
7. Open an unclear email attachment
About this, I don't want to say more, you should understand that things in the attachment may have to destroy the entire network with your hand.
In short, for your computer security, please remember to do the following things:
1. Be sure to remember to set a reliable password to your local administrator account and domain account and keep it. If you are convenient, you'd better replace a password two weeks.
2, you must remember the update system's patches. The company has implemented automatic distribution patches, if your system prompts you to use updates, please install these updates in time.
3, must remember to check the availability of enterprise version anti-virus software. If you find that your antivirus software is invalid (there is an exclamation or red circle on the small shield), please contact your administrator.
4. Don't install unknown software, including those so-called optimized system performance.
5, must lock the computer when leaving the computer.
