[SCP Foundation] [I-S-D] Internal Security Departm #3644258
Description
I-S-D is a concealed "Foundation within the Foundation", a special police force responsible for filtering traitors as well as operational and information security risks among the Foundation's ranks. The department is strictly hierarchical, adhering to defined multi-stage investigative protocol. Potential I- S-D agents must have a perfect service record and a length of Foundation service of more than a year. Usually, every I-S-D agent keeps his "official" position in order to provide his command a first-hand account of everything happening in a given department. The very existence of I-S-D is usually presented as a myth.
