DoS (Denial of service denial-of-service) and DDoS (distributed denial of service distributed Denial-of-service) attacks are one of the security threats to large Web sites and network servers. The attacks on Yahoo, Amazon and CNN in February 2000 were carved into the history of major security events. Because of its good attacking effect, SYN Flood has become the
. Prohibit the use of network access programs such as Telnet, Ftp, Rsh, Rlogin and Rcp, and replace them with PKI-based access programs such as SSH. SSH does not send passwords in plain text format on the Internet, while Telnet and Rlogin are the opposite. Hackers can find these passwords and access important servers on the network immediately. In addition, the. rhost and hosts. equiv files should be deleted on Unix. Because you do not need to guess the password, these files will provide logon a
