7 layers of security every computer should have

Every time you connect to the network, you are placing the computer and the information stored on your computer facing the dangers lurking online .

According to Roger Thompson, director of security for AVG Technologies , the most important thing for web users to remember is that 99% of attacks come from the web. So how to protect our computers and data?

Roger Thompson said that the best way is to protect the computer through security layers. If a protection area is only 75% effective, the other protection layers will fill the remaining holes. These protection classes should include:

Firewall Firewalls protect computers from attackers. There are many firewall options: including hardware, software and firewall firewalls in wireless routers.

Anti-virus, malware and spyware software . These software protect computers from viruses, Trojans, worms, rootkits and attacks. Today, these programs are often packaged as one. Because there are thousands of variants of malicious code that appear every day, it is difficult for software companies to keep up. Therefore, many users feel more secure when installing multiple security programs, if this program ignores a certain malicious code, it may be detected by another program.

Behavior monitoring . Behavioral surveillance, according to Roger Thompson, is to detect suspicious behavior of malicious code. For example, a new program that installs itself on a computer could be malicious code that records the operation of the keyboard.

Use a new browser version . Internet Explorer 8 may not be perfect, but it is much safer than IE6, Microsoft's outdated browser version still has a lot of users.

User management and network control software . An infected computer can destroy the entire network, so to make it more secure, control the website employees access through management policies on the server.

Data encryption software . Safe data should be stored by encrypting them.

Online backup system . This helps you to retrieve data in case the computer is stolen or broken.
