Potential Security Risks Caused by the Openness of IP Networks

Potential Security Risks Caused by the Openness of IP Networks

An open IP network has clear network architecture but also causes great potential security risks.

The IP network does not provide an authentication and authorization mechanism for terminal access, and therefore any terminal can access the IP network at will. Attackers can easily access the IP network and probe the IP address of a ME device, and then initiate attacks. In addition, they can easily simulate mass source IP addresses through address spoofing to initiate attacks on the ME device.

In the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, Layer 3 and lower layers have no security defense capabilities. Therefore, the application layer needs to ensure message integrity, authentication and authorization, and protocol consistency. As a result, attacks at Layer 4 or a lower layer usually target at the ME device.

The Ethernet network itself lacks identity authentication capabilities, which may easily cause MAC address spoofing attacks.

The IP stack is not designed with a security policy structure and therefore is susceptible to attacks.

The preceding potential security risks may expose networks to a variety of attacks, such as address spoofing attacks, replay attacks, malformed packet attacks, network viruses, message tampering, and traffic flooding, and therefore cause security problems.
