Controlled Security Mode
  • A mode of operation where internal security controls prevent inadvertent disclosure. Personnel, physical, and administrative controls prevent attempts to gain unauthorized access. The system may have users with access to the system who have neither the security clearance nor need-to-know for all classified information in the system. Access shall be limited to users with a minimal security clearance of one less than the highest classification information processed. (AFR 205-16;)
  • The mode of operation that is a type of multilevel security mode in which a more limited amount of trust is placed in the hardware/software base of the system, with the resultant restrictions on the classification levels and clearance levels that may be supported. (CSC-STD-003-85;)
  • The mode of operation that is a type of multilevel security mode in which a more limited amount of trust is placed in the hardware and software base of the system, with resultant restrictions on the classification levels and clearance levels that may be supported. The system may have users who possess neither the security clearance nor the need-to-know for all information in the system, however, access shall be limited to users with a minimal clearance level of one less than the highest classification processed. (NCSC-WA-001-85;)
  • An ADP system is operating in the controlled security mode when at least some personnel (users) with access to the system have neither a security clearance nor a need-to-know for all classified material then contained in the ADP system. However, the separation and controlof users and classified material on the basis, respectively, of security clearance and security classification is not essentially under operating system control as in the multilevel security mode.
