Keep systems guarded through the holiday period by preparing controls now, automating monitoring, and setting clear escalation paths for incidents. Follow a compact plan so your team and clients can enjoy the break without sacrificing security.
The most common holiday risks are unattended accounts, delayed detection, and phishing campaigns timed for slow periods. Threat actors know staffing is light and look for lapses in monitoring, expired credentials, or missed patches. Ransomware actors and credential-stuffing attempts spike during long weekends. Gift-card and invoice scams also increase as attackers leverage urgency and holiday language. Addressing these risks requires a mix of technical controls and staff awareness.
Start by patching all critical systems and confirming backups are current and tested. Enforce a change freeze on production environments to avoid introducing new risks. Update playbooks with on-call rotations, escalation contacts, and clear roles for incident response. Run a short readiness check—verify MFA, access logs, and monitoring rules are functioning. Document everything so anyone stepping in can act quickly.
Automation keeps watch when human attention is reduced by surfacing alerts and blocking suspicious actions. Use automated alerts for failed logins, unusual file transfers, and privilege escalations to get immediate visibility. Automated containment—like isolating an infected endpoint—limits damage until staff can respond. Make sure alert thresholds are tuned to avoid fatigue while still catching real threats. Automation should complement, not replace, a staffed escalation process.
Define a slim, well-documented on-call roster with clear escalation steps and contact methods. Keep the rotation small but ensure coverage for key time zones and peak holiday hours. Share a single source of truth for emergency contacts, recovery playbooks, and access credentials. Use scheduled reminders and test notifications so people know the process works. Compensate and respect on-call commitments to maintain morale and responsiveness.
Apply a change freeze after final updates and patches are complete—usually 24–48 hours before the holiday starts. The freeze prevents last-minute changes that could create new vulnerabilities or break monitoring. Allow emergency changes only with an approved exception process and post-change verification steps. Communicate the freeze broadly so clients and staff expect reduced change windows. Resume normal change procedures once monitoring and staffing return to full capacity.
Confirm backups are recent, complete, and stored offsite or in immutable formats before the break. Perform a quick restore test for critical systems to validate recovery procedures. Maintain documentation for who can initiate restores and how to verify integrity. Consider retention policies that cover extended downtime and ensure encryption keys are accessible to authorized responders. Regular testing reduces surprises when a restoration is needed.
Require MFA on all remote access and restrict admin access to known IP ranges where feasible. Review privileged accounts and remove or disable unused credentials before the holidays. Use VPNs or zero-trust access tools with short session durations and logging enabled. Monitor for atypical access patterns, like logins outside normal hours or from foreign locations. Enforce least-privilege so a compromised account cannot easily pivot to sensitive systems.
Send concise, actionable reminders that outline expected service levels, who is on call, and how to report incidents. Include tips on spotting holiday scams, like urgent payment requests or spoofed sender addresses. Provide clients with escalation contacts and expected response timeframes so they know what to expect. Share a short checklist—disable auto-pay requests, confirm backups, and update contact details. Clear communication reduces panic and speeds incident response.
Rely on tuned alerts for common indicators—failed authentication spikes, unusual data exports, and unknown devices joining the network. Prioritize high-confidence alerts and have a rapid triage rubric to decide when to escalate. Correlate events across systems (email, endpoint, network) to improve signal-to-noise. Keep a minimal set of responders who can take decisive containment steps. Logging and retention are critical so you can investigate incidents even after the holiday.
Ensure email filters are updated, enable DMARC/DKIM/SPF checks, and enforce MFA for financial or admin workflows. Train users to verify requests for payments or credential changes and to report suspicious messages. Implement rules to quarantine emails with unusual attachments or senders and use URL rewriting to analyze links. When a phishing campaign is detected, quickly block sender domains and update filters across tenants. Fast containment limits exposure while you assess impact.
Prioritize MFA, endpoint detection, logging, and tested backups—these controls reduce attack surface and speed recovery. Validate that monitoring tools cover critical assets and that alerting thresholds are realistic. Confirm remote access policies and revoke unused privileges. Review and update incident response documentation so responders can act without confusion. Investing effort in these basics yields the greatest protection during low-staff periods.
Run low-impact tabletop exercises that walk through likely scenarios and confirm roles and contact lists. Perform targeted validation—test backups, confirm alert delivery, and simulate an on-call notification. Avoid broad penetration testing during the break; instead, schedule that in advance. Use short rehearsals to validate that documentation and tools work under pressure. Small, repeatable checks build confidence without causing downtime.

Maintain coverage for the full holiday period with overlap between shifts; at a minimum, cover peak business hours and nights when incidents are likeliest to go unnoticed.
Yes—allow emergency changes only through a documented exception process with immediate post-change validation and rollback plans.
Test backups for critical systems at least once within the two weeks leading up to the holiday; more frequent checks are recommended for high-risk services.
Combine email filtering, DMARC/DKIM/SPF validation, enforced MFA, and concise user guidance—this layered approach cuts successful phishing attempts dramatically.
Keep rotations minimal and predictable, offer fair compensation for on-call shifts, and plan relief to avoid burnout; clear expectations help teams rest while keeping coverage effective.
