Research and application of server security protection based on virtual patch

In order to accelerate the transformation of energy and power and accelerate the informatization construction of the company, the number of business information systems of the company is increasing day by day, and the influence range of security events is becoming larger and larger, and the security protection of information system and network system becomes more complex and difficult. The traditional patch repair process takes a long time and has high professional requirements. It is easy to cause system compatibility problems and consumes more manpower, material resources and time. The virtual patch technology can provide vulnerability protection in time on the premise of ensuring the normal operation of business system, shorten the time required for testing and deploying key patches, eliminate the key vulnerabilities in servers and desktops, solve the problems of complexity and stability in the process of implementing patches in operational business application systems, and effectively block hacker and malicious code attacks.
