Ch.10 data security
contingency plan
"Documentation of the process for responding to a system emergency, including the performance of backups, the line-up of critical alternative facilities to facilitate continuity of operations, and the process of recovering from a disaster"
audit trail
(1) a chronological set of computerized records that provides evidence of information system activity (log-ins and log-outs, file accesses) used to determine security violations. (2) a record that shows who has accessed a computer system, when it was accessed, and what operations were performed
data integrity
(1) the extent to which healthcare data are complete, accurate, consistent, and timely (2) a security principle that keeps information from being modified or otherwise corrupted either maliciously or accidentally
examples of malware include:
-computer virus: a program that reproduces itself and attaches itself to legitimate programs on a computer. -computer worm: a program that copies itself and spreads throughout a network. unlike a computer virus, a computer worm does not need to attach itself to a legitimate program. It can execute and run itself. -trojan horse: a program that gains unauthorized access to a computer and masquerades as a useful function. Trojan horses may also copy and send themselves to e-mail addresses in a users computer. -spyware: a computer program that tracks an individual's activity on a computer system. cookies are a type of spyware. -backdoor programs: a computer program that bypasses normal authentication processes and allows access to computer resources, such as programs, computer networks, or entire computer systems. -rootkit: a computer program designed to gain unauthorized access to a computer and assume control over the operating system and modify the operating system.
an effective security program should contain the following components
-employee awareness including ongoing education and training -risk management program -access safeguards -physical and administrative safeguards -software application safeguards -network safeguards -disaster planning and recovery -data quality control processes
types of network safeguards
-firewalls -cryptography -encryption -digital signatures -digital certificates -web security protocols -intrusion detection systems
what are the types of access safeguards?
-identification -authentication -passwords -smart cards and tokens -biometrics -two-factor authentication -single sign-on -authorization -
An effective data security program embodies three basic elements to help prevent system or access errors from occurring:
-protecting the privacy of data -ensuring the integrity of data -ensuring the availability of data
there are 3 different types of information that can be used for authentication
1. something you know 2.something you have 3.something you are
Security rule standards are grouped into five categories:
1.administrative safeguards 2.physical safeguards 3.technical safeguards 4.organizational requirements 5.policies and procedures and documentation requirements
one common application control is
1.authentication 2.audit trail 3.edit check
organizational requirements include two standards
1.business associate or other contracts 2.group health plan requirements

(3) To provide investments needed to increase economic efficiency by spurring technological advances in science and health. (4) To invest in transportation, environmental protection, and other infrastructure that will provide long-term economic benefits. (5) To stabilize state and local government budgets, in order to minimize and avoid reductions in essential services and counterproductive state and local tax increases

true
the role based access control (RBAC) is the one used most often in health care organizations
true
Strong authentication requires providing information from two of the three different types of authentication information:
two factor authentication
administrative safegaurds
under HIPAA, are administrative actions and policies and procedures, to manage the selection, development, implementation and maintenance of security measures to protect electronic protected health information and to manage the conduct of the covered entity's or business associate's workforce in relation to the protection of that information.
The institute of medicine (IOM) reports that correct medication administration increases when hospitals
use well-designed, robust computerized drug ordering systems and barcodes, but poorly designed systems can create hazards.
responses to an incident include
workforce notification, preserving evidence, mitigating harmful effects caused by the breach and evaluating the incident as a part of the organization's risk management process.
