The University of Nebraska Medical Center (UNMC) is an institution that was built back in the 19th century. UNMC’s mission is to improve the health of Nebraska through premier educational programs, innovative research, the highest quality patient care, and outreach to underserved populations (UNMC, 2004). As an institution with key interest to privacy of its students, staff and subordinate staff, UNMC has adopted various policy guidelines to ensure information security system. The Information Security Management Plan (ISMP) describes its safeguards to protect confidential information.
These safeguards are meant among another reason to:
Ensure the confidentiality of data
Ensure the integrity of data
Ensure the availability of data
Protect against anticipated threats or hazards to the security or integrity of the information UNMC has adopted information security industry best practices to implement its information security system (UNMC, 2014). They have become so effective that during 2011, a Hitrust Gap assessment was performed, and no significant gaps were found within its security program. The worksheet below outlines how these programs have been rolled out by different offices in the university.
