Vital Signs

An acceptable use policy, or AUP, tells employees and other workforce members how they may use an organization’s technology and data. This post explains what a good AUP covers, how it connects to HIPAA workstation, training, and sanction requirements and to NIST rules of behavior, and what the NCSBN social media guidance adds for nurses.

A security administrator is a trained member of the data system management team who manages, monitors, and administers security over one or more networks and helps create a confidentiality-conscious working environment. This post explains the role, how it differs from the HIPAA-required security official, typical duties, safeguards for privileged accounts, and how nurses work with security administrators.

In security, penetration means an intruder gains or attempts to gain unauthorized access to a system or resource. Penetration testing is the authorized practice of simulating that attack to find weaknesses first. This post explains the difference between penetration, penetration testing, vulnerability scanning, and risk analysis, proposed HIPAA requirements, and safety cautions in clinical environments.

Identity proofing is the process of collecting and checking enough evidence to establish who a person is before issuing credentials or granting access. This post explains how proofing differs from authentication, the NIST identity assurance levels, where it appears in EPCS, patient portals, and workforce onboarding, and what nurses should know.

The CIA triad is a model for guiding information security policy built on three goals: confidentiality, integrity, and availability. This post explains each goal, how the HIPAA Security Rule requires protecting all three for electronic protected health information, healthcare examples of each, how the goals sometimes conflict, and what nurses do every day to uphold them.

Wi-Fi Protected Access is the family of security protocols that protect wireless networks, created to replace the weak Wired Equivalent Privacy standard. This post explains WPA, WPA2, and WPA3, personal versus enterprise modes, the risks of legacy medical devices, NIST guidance for wireless networks, and what nurses and informaticists should know.

An incident is an event with the capacity to cause loss or disrupt operations if it is not managed. In health care the word covers patient safety events, security incidents, and operational disruptions. This post explains how HIPAA and NIST frame security incident response, how patient safety event reporting works and where it falls short, and the nurse’s role.

Accountability in health information means being able to identify the person, organization, device, or software responsible for creating, changing, verifying, accessing, disclosing, or transmitting data. This post explains why accountability matters, how unique identification, audit trails, electronic signatures, and provenance support it, challenges with devices and AI, and nursing roles.

Identity and access management (IAM) is the set of policies, processes, and technologies that create and manage digital identities and control what each identity can access. This post explains IAM components, from provisioning and authentication to single sign-on and privileged access, why IAM is central to healthcare security, common gaps, and what nurses experience.

Bring your own device (BYOD) is a policy that allows staff to use personally owned smartphones, tablets, or computers for work. This post explains why healthcare organizations adopt BYOD, the privacy and security risks of personal devices handling PHI, controls such as mobile device and application management, secure messaging, and policies, and what BYOD means for nurses.

The HIPAA Privacy Rule sets national standards for protecting individually identifiable health information and gives patients rights over their health information. This post explains whom the rule covers, when PHI may be used and disclosed, patient rights such as access and amendment, the minimum necessary standard, how the rule relates to the Security Rule and other laws, and what it means for nurses.

Public key infrastructure (PKI) is the combination of technology, policies, people, and procedures that manages digital certificates and public key cryptography. This post explains how key pairs, certificates, and certificate authorities create trust, how PKI supports encryption and digital signatures in healthcare, why certificate lifecycle management matters, and what nurses should know.

Biometrics are measurable physical or behavioral characteristics, such as fingerprints, facial features, or palm vein patterns, used to identify people or verify their identity. This post explains how healthcare uses biometrics for patient identification and clinician authentication, how they fit with multifactor authentication, accuracy and privacy concerns, and what nurses should know.

Anonymization removes or replaces identifying information so that data can no longer be linked to an individual. This post explains how anonymization differs from pseudonymization and HIPAA de-identification, why re-identification remains a real risk, how European and U.S. law treat anonymized data, and how health systems use these techniques for research, analytics, and AI.

A zero-day attack exploits a software vulnerability before the vendor knows about it or has released a fix. This post explains how zero-day vulnerabilities are discovered and exploited, why they are especially concerning for hospitals with many vendors and medical devices, how they differ from known unpatched vulnerabilities, and the layered defenses that limit damage.

Social engineering is the manipulation of people into breaking security practices, revealing information, or granting access. This post explains common social engineering tactics, from phishing and phone pretexting to help desk scams and tailgating, why healthcare is an attractive target, how attackers exploit trust and urgency, and practical steps nurses and organizations can take.

Encryption transforms readable data into ciphertext that can be read only with the correct key. This post explains symmetric and public key encryption, protecting data at rest and in transit, how HIPAA treats encryption, why properly encrypted data can avoid breach notification, the importance of key management, and what post-quantum cryptography means for healthcare.

A risk analysis is the process of understanding the nature of risk and determining its level. In healthcare, the HIPAA Security Rule requires an accurate and thorough analysis of risks to electronic protected health information. This post explains the steps of a security risk analysis, how it connects to risk management, why OCR emphasizes it in enforcement, and how clinicians contribute.

The HIPAA Security Rule sets national standards for protecting electronic protected health information (ePHI) through administrative, physical, and technical safeguards. This post explains what the rule requires, how required and addressable specifications work, how it relates to the Privacy Rule, what the proposed update would change, and what it means for nurses.

Authorization is the security process that determines what an authenticated user or application is allowed to access or do within a system. This post explains how authorization differs from authentication and from a HIPAA authorization form, common access control models, how authorization works for apps and APIs, and what it means for nurses in daily workflow.
