For Linux system security vulnerabilities and preventive measures-Linux Enterprise Application-Linux server application information, see the following for details. LINUX is a free operating system widely used in the world today. It is fully compatible with UNIX, but with its open platform, it attracts countless students and researchers from colleges and universities to take it as the object of study and research. These programming experts are constantly improving the network security functions in LINUX. Next we will introduce Linux's Internet Security Vulnerabilities and preventive measures, hoping to help you. LINUX Internet security mainly includes FTP security, Email Security, Telnet security, Web server security, and secure Web protocol.
Web Server Security
To protect Web host security, remove unnecessary services. Before removing unnecessary services, you must first specify the type of host you want to create. There are three types of hosts:
Intranet Web host-a host without Internet connection, usually connected to a LAN.
Private or external Web hosts-hosts that are connected to the Internet but only provide services to very limited customers.
Public or sacrifice Web hosts-a common Web host that users who know or do not know can access the Internet around the clock.
Different host types determine the provision of different services, and all unnecessary services are blocked. This is because the running service may open security vulnerabilities. Access control is required for services to run. You can use the TCPWrapper toolkit, which provides access control for remote services based on pattern matching, it can be used to prohibit or allow services to some users. After the service is reduced, access control and authentication should be established on the Web server. Apache is the most popular Web server in LINUX. To create rules for network access control, you must use the following command:
CODE: # Controls who can get stuff from this server.
Order allow, deny
Allow from all |
