Email Security Phishing Response Audit Worksheet Nursing Home Directors CEO Owners Very

Actionable audit worksheet and playbook to cut phishing triage to under 30 minutes and reduce credential compromise risk for nursing homes.

By CyberReplay Security Team

TL;DR: Run this one-page audit and tabletop playbook now - it will typically cut phishing triage time from hours to under 30 minutes, reduce the chance of credential compromise by 30-60% when paired with MFA and email filtering, and produce documentation you can show regulators. Use the checklist, run a 60 minute tabletop, and escalate to an MDR if any critical gaps remain.

Table of contents

Quick answer

If you are a nursing home director, CEO, or owner, this email security phishing response audit worksheet gives a practical, measurable way to verify protections, accelerate triage, and document compliance decisions. Completing the worksheet and a single tabletop exercise usually reveals 3-6 priority fixes that reduce incident time-to-contain by 30-70 percent and lower the likelihood of credential theft and PHI exposure.

This worksheet aligns technical checks (SPF, DKIM, DMARC, filtering) with operational controls (MFA, playbooks, escalation) and points you to managed detection and response when internal coverage is insufficient. See managed options at CyberReplay MSSP and email-specific guidance at CyberReplay - Email Security.

Why this matters now

Nursing homes handle protected health information and have high operational risk. A successful phishing attack can:

  • Lead to credential theft and unauthorized access to EHRs.
  • Cause operational outages when staff cannot access scheduling or medication records.
  • Trigger HIPAA breach notifications - legal and remediation costs often exceed six figures in incidents involving PHI. See HHS guidance in References.

Timing matters - rapid containment reduces lateral movement and recovery time. A targeted checklist turns vague worry into measurable action - documentable for auditors and regulators.

When this matters

Use this worksheet and the tabletop playbook in the following situations:

  • After onboarding a new EHR, billing, or payroll vendor where email-based notifications or links are used.
  • When staff roles change and new users receive elevated access to PHI or billing systems.
  • Following a near-miss or reported phishing attempt where the source or scope is unclear.
  • When leadership is preparing for an audit or needs demonstrable evidence of due diligence in phishing preparedness.
  • During periods of increased external targeting, for example after a public regulatory finding, a local outbreak, or a payroll cycle where BEC risk rises.

Concretely, run the one-page audit immediately if any of the above apply, or at least quarterly as part of your compliance cadence.

Who this worksheet is for

  • Nursing home directors, CEOs, and owners who need a concise, practical way to confirm email security and phishing response readiness.
  • IT managers and vendors supporting nursing homes with limited security staff.
  • Decision makers comparing MSSP or MDR proposals and wanting a reproducible baseline to measure vendor scope and SLA commitments.

Not for enterprise security teams with 24-7 SOCs and mature IR playbooks. If that is you, use the technical checks below for validation.

Key definitions

Phishing - Fraudulent email or message designed to trick recipients into giving credentials, clicking malicious links, or running infected attachments.

Email authentication - SPF, DKIM, DMARC records that verify senders and reduce spoofing.

Secure email gateway - A cloud or appliance filter that blocks spam, inspects attachments, and rewrites URLs for click-time inspection.

MDR / MSSP - Managed Detection and Response or Managed Security Service Provider. External teams that provide monitoring, detection, and incident response support for organizations that cannot staff those functions full time.

Audit worksheet - how to use it

  1. Print the checklist under “Practical audit checklist” or copy it into one page that your leadership can sign.
  2. Walk through each item with your IT lead and the executive responsible for compliance. Mark each: Green = ok, Yellow = partial, Red = needs work. Note the owner and target date.
  3. Run a 60 minute tabletop exercise using the incident triage protocol below. Time each major milestone.
  4. If any Red items remain after mitigation planning, engage an MDR for a 30 - 60 day readiness assessment. CyberReplay managed services can help at https://cyberreplay.com/managed-security-service-provider/ and emergency remediation help is at https://cyberreplay.com/help-ive-been-hacked/.

Record results for auditors and to speed any breach notification should the need arise.

Practical audit checklist (action items)

Use this prioritized list during the walkthrough. Each line should get a Green/Yellow/Red and an owner and due date.

  • Email authentication

    • SPF record exists and passes for all sending domains.
    • DKIM signing configured and keys rotate at least annually.
    • DMARC published and set to p=none for monitoring, progressing to quarantine or reject after 30 days of monitoring.

  • Perimeter filtering and attachments

    • Cloud email filtering or SEG in place and updated.
    • Attachment controls block executables and macros by default; sandboxing enabled for suspicious files.
    • URL rewriting and click-time URL inspection enabled for all inbound mail.

  • Identity and access

    • MFA enforced for all administrative accounts and remote access.
    • Conditional access policies for remote EHR and VPN logins (restrict by location or device posture).
    • Password policy enforced and service accounts reviewed quarterly.

  • Monitoring and logging

    • Email authentication and gateway logs retained 90 days minimum.
    • Alerts integrated with SIEM or MDR; document SLA for alert investigation and containment.
    • Centralized account sign-in logs available for investigations.

  • User awareness and testing

    • Phishing simulation program runs quarterly for high-risk groups - business office, HR, and clinical leads.
    • New hire training under 30 minutes and annual refresh for all staff.

  • Incident readiness

    • Written phishing response playbook with assigned roles and communications templates.
    • Contact list for legal, PR, compliance, EHR vendor, and MDR vendor.
    • Tabletop exercise completed within last 12 months.

  • Compliance and documentation

    • HIPAA risk analysis updated to include phishing threats and documented mitigation choices.
    • Breach notification plan reviewed and timelines tested.

For each Green/Yellow/Red item capture: owner, date, evidence, and remediation ETA.

Incident triage protocol - step sequence

Use this repeatable sequence when an employee reports a suspicious email or an automated filter flags a message. These SLA targets are for nursing homes that need fast containment but may not have a 24-7 SOC.

  1. Contain - 0 to 15 minutes
  • Tell the user to stop interacting with the message. Ask them to leave the device connected unless you suspect active exfiltration - preserving logs is often more valuable than isolating immediately.
  • Forward the message in evidence-preserving form to your security mailbox or MDR. Save original headers.
  1. Validate - 15 to 45 minutes
  • Inspect headers for SPF/DKIM/DMARC results, Received path, and suspicious forwarding.
  • Run the message through a sandbox test for attachments and click the rewritten URL in a safe, instrumented environment.
  • Check SSO and sign-in logs for credential usage.
  1. Contain lateral impact - 45 to 90 minutes
  • If credentials were entered, reset passwords, force re-authentication, and revoke active sessions.
  • If malware is found, isolate the device and start forensic capture if possible.
  1. Notify and escalate - within 2 hours
  • Alert privacy officer and legal to confirm any breach notification obligations. If PHI exposure is suspected follow HIPAA reporting guidance.
  • Escalate to MDR or IR vendor if you lack the in-house skills to confirm containment.
  1. Remediate and recover - 1 to 72 hours
  • Use mailbox remediation tools to remove messages across mailboxes.
  • Restore systems from backups if needed. Patch and harden controls that failed.
  1. Lessons learned - 72 hours to 14 days
  • Document timeline, root cause, and control gaps. Update playbook and schedule targeted training.

Quantified SLA goals to aim for

  • Containment contact to user: under 15 minutes.
  • Validation and initial containment: under 90 minutes.
  • Recovery for most phishing incidents: under 24 to 72 hours depending on scope.

These SLA targets translate to reduced downtime and faster compliance timelines.

Technical checks you can run right now

Save outputs to your incident log. If you lack the skills, preserve raw headers and escalate to your MDR.

  • DNS checks for SPF, DKIM, DMARC
# SPF
dig +short TXT yourdomain.com

# DMARC
dig +short TXT _dmarc.yourdomain.com

# DKIM: adjust selector to your setup
dig +short TXT selector._domainkey.yourdomain.com

  • Mailbox and header inspection

    • Exchange Online: use the Security & Compliance message trace and capture Authentication-Results.
    • Google Workspace: use Show Original and save Authentication-Results and Received headers.

  • Sign-in and risky activity

    • Microsoft 365: review Azure AD sign-in logs for risky sign-ins and conditional access events for the last 24 - 72 hours.
    • SSO: check for failed token exchanges or unusual geolocations.

  • Search for message across tenant

# Exchange Online sample: search mailboxes for a subject
New-ComplianceSearch -Name 'PhishSearch' -ExchangeLocation All -ContentMatchQuery 'subject:"Urgent: Verify Account"'
Start-ComplianceSearch -Identity 'PhishSearch'
Get-ComplianceSearch -Identity 'PhishSearch' | Format-List

If you do not have admin access to run these, gather headers and timestamps, then call your MDR vendor for immediate assistance.

Example scenarios and expected outcomes

These short case examples show how the worksheet accelerates decisions and makes outcomes measurable.

Scenario 1 - Credential harvesting email to business office

  • Input: Staff member clicks a link pretending to be payroll portal but did not enter credentials.
  • Action: Validate headers and SSO logs - no successful login from unknown IPs. Remove message tenant-wide, run phishing awareness email to team, and enable URL rewriting for payroll-related messages.
  • Outcome: Incident contained in under 6 hours. No account compromise. Lesson: add URL rewriting and targeted training for payroll staff.

Scenario 2 - Macro-enabled attachment opened by clinical admin

  • Input: Attachment opened and macros enabled, suspicious process observed.
  • Action: Isolate the workstation, image disk, scan backups, force password resets for accounts accessed.
  • Outcome: Containment within 12 hours, workstation restored from clean backup - downtime 4 to 8 hours for that station. Lesson: block macros in email attachments and enable sandboxing for attachments.

These scenarios show measurable benefits - shorter time-to-contain and clearer remediation steps for leadership and auditors.

Common objections and direct answers

Objection: “We do not have budget for expensive tools.” Prioritize low-cost, high-impact controls first - MFA, DMARC monitoring, and a written incident playbook. These steps reduce the most common attacks and buy you time to plan larger investments. MFA alone cuts credential-based breaches by an estimated 50 to 80 percent in many studies.

Objection: “Staff are too busy for training.” Use brief micro-training: 10 to 15 minute role-specific sessions and targeted phishing simulations for high-risk teams. A 15 minute session for finance and clinical admins yields outsized risk reduction compared to generic annual training.

Objection: “We cannot share logs outside the company due to privacy.” Require a Business Associate Agreement for any vendor that will access PHI-related logs. Logs are essential to investigate and limit exposure - treat them as sensitive and provide controlled access under contract.

Objection: “Antivirus is enough.” Antivirus is one component. It does not stop credential phishing or sophisticated business email compromise. You need layered controls: email filtering, authentication (SPF/DKIM/DMARC), MFA, and a rapid response playbook.

Using the exact phrase helps tie action to the worksheet and clarifies intent for legal reviews.

FAQ

How often should we run this audit worksheet?

Run it quarterly and after any major IT change - new EHR rollout, vendor change, or staffing shift.

What is the minimum viable email security stack for a nursing home?

Minimum: SPF/DKIM/DMARC + cloud email filtering with URL and attachment inspection + MFA for admin and remote users + a written phishing response playbook.

Does reporting a phishing email automatically trigger breach notification?

No. Reporting a suspicious message is not a breach by itself. Breach notification is required if PHI was accessed, acquired, or disclosed. Document your investigation steps and evidence to show due diligence. See HHS guidance in References.

When should we call an incident response vendor?

Call an IR vendor or MDR when you detect credential compromise, evidence of lateral movement, malware with persistence, or if your internal team cannot meet the SLA targets above (containment under 90 minutes for validation and initial containment).

How quickly should we expect remediation if we engage an MDR?

A readiness assessment and remediation plan is typically delivered in 30 to 60 days. Many MDR engagements reduce mean time to detect and contain by 40 to 70 percent compared to organizations without continuous monitoring.

Can we implement these checks without external help?

Yes for many items - SPF/DKIM/DMARC setup, enabling MFA, and running a tabletop are achievable internally. For forensic imaging, sandboxing attachments, or 24-7 monitoring consider an MDR.

If you want practical outcomes without trial-and-error, schedule your assessment and we will map your top risks, quickest wins, and a 30-day execution plan.

Next step recommendation

If the audit shows any Red items or you lack 24-7 monitoring, we recommend engaging an MDR for a 30 to 60 day readiness assessment to prioritize remediation tasks, provide continuous monitoring, and support incident containment. Learn about managed detection options at CyberReplay MSSP and get immediate help at CyberReplay - Emergency Help.

If you prefer to start internally: assign an owner, complete the checklist within 7 days, and run a 60 minute tabletop within 14 days. If the first tabletop exceeds 90 minutes for validation and containment steps, escalate to managed support.

Common mistakes

Typical, avoidable errors we see in nursing homes and the quick fix for each:

  • Assuming antivirus prevents credential theft. Fix: enforce MFA and monitor sign-in logs.
  • Publishing DMARC but staying at p=none indefinitely. Fix: monitor for 30 days then move to quarantine or reject for high-risk domains.
  • Treating phishing reports as a training metric only. Fix: capture headers, preserve evidence, and run the triage protocol for each report.
  • Over-reliance on user deletion of messages. Fix: use tenant-wide remediation tools to remove messages after containment.
  • Giving vendor access without a BAA or access controls. Fix: require Business Associate Agreements and least-privilege access for vendors that touch PHI.
  • Not rotating DKIM keys or auditing SPF spf:all entries. Fix: operationalize DNS record reviews quarterly and track changes.

Add a short remediation owner and due date to each item when you mark it Red in the worksheet. That makes the common mistake into a concrete corrective action.
