Some basic protection and network security for home computers

Frequent antivirus, clean up system junk, do not open unintended ** and receive files from strangers

It's all on it, I'm really lazy not to check.

Summary. 1.Install antivirus softwareFor the average user, the first thing to do is to install a set of genuine antivirus software for the computer to prevent the computer from being infected with viruses.

Due to the emergence of new viruses one after another, the virus database of each antivirus software is updated frequently, and the virus database of the antivirus real-time monitoring program should be updated regularly every day to ensure that it can resist the attacks of the latest viruses. 2.Install a personal firewall to protect against hackers.

"Firewall" refers to a method of separating the intranet from the public access network, and is an isolation technique. The program can keep out people and data who "disagree". 3.

Categorize and make password settings as complex as possible (1) Use different passwords for different occasions. There are many places that need to set passwords on the Internet, such as online banking, online accounts, e-mail, chat rooms and some ** members. Whenever possible, use different passwords to avoid all data leakage due to one password leakage.

For important passwords, such as those for online banking, be sure to set them separately and not be the same as other passwords. (2) When setting a password, try to avoid using meaningful English words, initials, birthdays, ** numbers and other easily leaked characters as passwords, and it is best to use a password that mixes characters and numbers.

At present, the commonly used technical measures to protect the security of computer networks are firewall technology.

Firewall technology can not only prevent abnormal access to the protected network from the external network, but also prevent insecure access to the external network from within the system.

To a certain extent, a firewall creates an insurmountable layer of protection between the protected network and the external network. Any access operation must be authenticated, filtered, and permitted by the protective layer, and only information exchanges that have been authenticated and authorized by the firewall can pass through the operation

How to strengthen the computer network system

1. Strengthen facility management, establish and improve the safety management system, and prevent illegal users from entering the computer control room and the occurrence of various illegal behaviors; Focus on protecting computer systems, network servers, printers and other hardware entities and communication lines from natural disasters, vandalism and wire attacks; Verify the identity and use rights of users, prevent users from unauthorized operations, and ensure the physical security of computer network systems.

2. Strengthen access control policies. Access control is the main strategy of network security prevention and protection, and its main task is to ensure that network resources are not illegally used and accessed. Various security policies must cooperate with each other to truly protect each other, but access control is one of the most important core strategies to ensure network security.
