This standard establishes a framework for ensuring that servers deployed within UMB’s campus are managed in a secure and predictable fashion. It is the responsibility of UMB network managers to protect and maintain the security of the networks they are charged with managing. System administrators are obliged to prevent trespassers from corrupting or misusing any segment of the enterprise network. Listed below are recommended standards to be followed by system administrators where technically feasible.
Scope
UMB is a distributed environment with corresponding local responsibilities. Support for campus enterprise applications is managed centrally. This security standard is recommended for all server resources within the physical area of the UMB campus and all users who access those resources. It pertains especially to those resources that support vital business functions and that maintain confidential, personal, or protected information.
