People's hospital network isolation and information exchange construction needs
In view of the current network situation, according to the planning of informatization construction of our hospital, the following objectives should be achieved:
From the perspective of management and technology, establish a multi-layer security system to ensure the security and confidentiality of hospital network information and various systems.At the same time, while maintaining the isolation of hospital medical insurance, Internet and various hospital systems, moderate and controllable data exchange between internal and external networks is carried out.Protect the security of each system network of the hospital, achieve isolation, prevent the attack of hackers outside the network. Record the hospital data center network, hospital file exchange and mail transfer log in detail, so as to keep records.
Internal networks can easily be attacked by malicious intruders from external networks.
1- The intruder USES Sniffer and other Sniffer programs to detect and scan the network and operating system security vulnerabilities, such as network IP address, the type of application operating system, which TCP port number to open, the system to save user name and password and other security information key files, and through the corresponding attack program to attack the internal network.
2- Intruders obtain the user name, password and other information of Intranet users through network monitoring and other advanced means, and then fake the internal legal identity to log in illegally and steal important information of Intranet.
3- Malicious attack: the intruder sent a large number of pings to the Intranet important service, so that the server overworked to the denial of service and even the system crashed.
