Using a high safety factor Password

To improve the security of one of the simplest and most effective way is to use a violent attack will not be easily guessed passwords.
What is a violent attack? An attacker to use an automated system to guess passwords as quickly as possible with hope, will soon find the correct password. Use contain special characters and spaces, using both uppercase and lowercase letters, avoid using from the dictionary to find words, do not use pure digital password, this password cracking up than your mother's name or use your birthday as a password to be difficult to more.
In addition, you have to remember your password for each so that the length of one, you'll see multiple levels of additional characters from your password posed by the combination. Half of the run, less than 8-character password is considered very easy to break. Can be 10, 12 characters for the password, 16, of course better. In the type will not be too long and difficult circumstances, to make your password longer will be more secure as much as possible.

Good border protection

Not all security problems have occurred in the system Desktop On. Use an external firewall / router to help protect your computer is a good idea, even if you have only one computer.
From the low-end considerations, you can purchase a broadband router device, for example, can be purchased from the Internet to the router and so on. From the high-end considerations, you can use the enterprise-class vendors Managed switches, routers and firewalls and other security equipment. Of course, you can also use pre-packaged firewall / router setup to yourself to create its own protective equipment. Proxy server, anti-virus gateways, and spam filtering Gateway Also contribute to a very strong border security.

Re: How to improve the security level of the operating system

In many cases, install the software before deploying production applications on the system, patch testing is crucial, the ultimate security patches must be installed on your system. If no security updates for a long time may lead to the computer you are using very easily become targets of unscrupulous hackers. Therefore, do not install the software patches for security in the long run there is no update on the computer.
The same situation also applies to any signature-based malware protection tools, such as anti -Virus Application, if it does not make timely updates, which cannot be the current malicious software feature definition, protective effect will be greatly reduced.

Re: How to improve the security level of the operating system

In most cases, many computer users do not even know their systems which can be run on a network access service, which is a very dangerous situation.
Telnet and FTP are two common problems, so if your computer do not need to run them, then immediately close them. Make sure you understand each one running on your computer what each service is doing what, and know why it wants to run.
In some cases, this may require you to find out which service is very important to you, so you will not commit, such as in a Microsoft Windows computer, turn off RPC services, such a mistake. However, you actually do not turn off the service is always a correct idea.

Re: How to improve the security level of the operating system

For those who are security-conscious computer users or system administrators, there are different levels of data encryption, the scope can be used as needed to choose the right level of encryption is normally based on the specific circumstances to decide.
A wide range of data encryption, from the use of passwords tool to encrypt files one by one, and the file system encryption, and finally to the whole disk encryption. In general, these encryption levels are not included on the boot partition is encrypted, because that would require decryption assistance from specialized hardware, but if you have a secret important enough to warrant the cost of this part of the money, he can achieve this right as a whole system of encryption. In addition to boot partition encryption, there are many kinds of solutions to meet the needs of each level of encryption, which encompasses both commercial proprietary systems, but also in each and every major desktop operating system on the opening of the whole disk encryption source system.
