Rule Category

PROTOCOL-SCADA -- Snort alerted on SCADA protocol activity. SCADA is used in Industrial Control Systems (ICS), programmable logic controllers for large scale systems, such as water treatment facilities. SCADA systems often require no authentication and use generic commands that are hard to screen for. Snort rules look for specific hardware and the traffic protocols they use, as these are often tied to a specific port or URI request.

Rule Vulnerability

Buffer Overflow

Buffer Overflows occur when a memory location is filled past its expected boundaries. Computer attackers target systems without proper terminating conditions on buffers, which then write the additional information in other locations in memory, overwriting what is there. This could corrupt the data, making the system behave erratically or crash. The new information could include malicious executable code, which might be executed.
