[Network Security] What is vulnerability scanning? What are its functions?

  Recently, many friends have asked me what is vulnerability scanning? What are the functions of vulnerability scanning? I believe many people do not know much about this. Oldboy Education has compiled an article, hoping that this article can help you.

  What is vulnerability scanning?

  Vulnerability scanning refers to a security detection (penetration attack) behavior that detects the security vulnerabilities of a specified remote or local computer system through scanning and other means based on the vulnerability database, and discovers exploitable vulnerabilities.

  Vulnerability scanners include different types such as network leak scans, host leak scans, and database leak scans.

  What are the vulnerability scanning functions?

  Vulnerability scanning technology is an important type of network security technology. It cooperates with firewalls and intrusion detection systems to effectively improve network security. By scanning the network, network administrators can understand the network's security settings and running application services, discover security vulnerabilities in a timely manner, and objectively assess network risk levels.

  Network administrators can correct network security vulnerabilities and incorrect settings in the system based on the scan results to prevent hackers from attacking. If firewalls and network monitoring systems are passive defense methods, then security scanning is a proactive preventive measure that can effectively avoid hacker attacks and nip problems in the bud.

  1. Regular network security self-testing and assessment

  Equipped with a vulnerability scanning system, network managers can regularly conduct network security testing services. Security testing can help customers eliminate security risks to the greatest extent possible, discover and repair security vulnerabilities as early as possible, effectively utilize existing systems, optimize resources, and improve The operating efficiency of the network.

  2. Check after installing new software and starting new services

  Since vulnerabilities and security risks come in many forms, installing new software and starting new services may expose previously hidden vulnerabilities. Therefore, you should rescan the system after performing these operations to ensure security.

  3. Security planning evaluation and effectiveness inspection

  Equipped with a network vulnerability scanning/network assessment system, you can easily conduct security planning evaluation and effectiveness testing.

  4. Safety testing before undertaking important tasks

  Before the network undertakes important tasks, it should take more proactive security measures to prevent accidents, strengthen the emphasis on network security and information security from a technical and management perspective, form a three-dimensional protection, change from passive repair to active prevention, and ultimately reduce the probability of accidents. drop to lowest.

  5. Analysis and investigation after network security incidents

  After a network security incident, network vulnerability scanning/network assessment system analysis can be used to determine the vulnerabilities of the network being attacked, help fill the vulnerabilities, and provide as much information as possible to facilitate investigation of the source of the attack.

  6. Preparation before major network security incidents

  The network vulnerability scanning/network assessment system before major network security incidents can help users find out the hidden dangers and vulnerabilities in the network in a timely manner, and help users make up for the vulnerabilities in a timely manner.
