1. Intrusion detection technology
When using computer software to study or work, most users will face improper program design or configuration problems, if the user can not solve these problems in time, make others more easily to invade their own computer system. For example, hackers can use program vulnerabilities to break into other people's computers, steal or damage information resources, causing a certain degree of economic losses to others. Therefore, users must deal with bugs in a timely manner when they occur, and can solve the problem by installing bug patches. In addition, intrusion detection technology is also willing to more effectively guarantee the security of computer network information, the technology is the combination of communication technology, cryptography technology and other technologies, reasonable use of intrusion detection technology users can timely understand the existence of various security threats in the computer, and take certain measures to deal with.
2. Firewall and virus protection technology
Firewall is an important technology that can effectively protect computer security. It is composed of hardware and software equipment to prevent the intrusion of external network by establishing detection and monitoring system. Users can use the firewall to effectively control the access of external factors to the computer system to ensure the confidentiality, stability and security of the computer. Virus protection technology refers to the installation of anti-virus software for security defense, and timely update the software, such as kingsoft poison bully, 360 security protection center, computer security housekeeper. The main function of virus protection technology is to monitor the computer system in real time, at the same time to prevent the virus from invading the computer system and causing harm to it, intercept and eliminate the virus, and realize the security protection of the system. In addition, the user should also take the initiative to learn the knowledge of computer security protection, when downloading resources on the Internet, try not to choose unfamiliar sites, if you must download the download of good resources for antivirus processing, to ensure that the resources will not cause negative impact on computer security operation.
3. Digital signature and biometrics
Digital signature technology is mainly aimed at e-commerce, which effectively ensures the confidentiality and security of information transmission, and can also avoid malicious attacks or attacks on computers. Biometrics refers to the identification of human features to decide whether to give the right to apply, mainly including fingerprints, retina, voice and other aspects. This kind of technology has the determination pertinency, can guarantee the computer Internet information security to the greatest extent, now the most widely used is the fingerprint identification technology, this technology in the security and confidentiality on the basis of stable and simple characteristics, has brought great convenience for people.
4. Information encryption and access control technology
Information encryption technology means that users can encrypt files that need to be protected, set complex passwords with certain difficulty, and keep them in mind to ensure their effectiveness. In addition, the user should also carry on the regular overhaul to the computer equipment and for the household, strengthens the network security protection, and carries on the real-time monitoring to the computer system, prevents the network intrusion and the risk, thus guarantees the computer security stable operation. Access control technology refers to setting access rights for certain information through users' customization, or implementing access restrictions by using control functions. This technology can protect user information and avoid illegal access to such situations.
5. Virus detection and removal technology
6. Safety protection technology
Includes network protection technology (firewall, UTM, intrusion detection and defense, etc.); Application of protection technology (such as application program interface security technology, etc.); System protection technology (such as tamper-proof, system backup and recovery technology, etc.) to prevent external network users from entering the internal network by illegal means, access to internal resources, and protect the internal network operating environment related technology.
7. Safety audit technology
Including log audit and behavior audit, through log audit to assist the administrator to look at the network log after being attacked, so as to evaluate the rationality of network configuration, the effectiveness of security policy, trace analysis of security attack trajectory, and provide means for real-time defense. Ensure compliance of information and network usage by auditing the network behavior of employees or users.
8. Safety detection and monitoring technology
The traffic and application content in the information system should be detected on two to seven levels and appropriately monitored and controlled to avoid the abuse of network traffic, the spread of spam and harmful information.
9. Decryption and encryption technology
Encryption and decryption of information data in the transmission or storage process of an information system.
10. Identity authentication technology
Techniques used to determine the legality of accessing or intervening in the identity of an information system user or device, typically with username and password, identification, PKI certificates, and biometric authentication.
