Don’t Let Your Guard Down This Summer: Cybersecurity Risks During Vacation Season 

Summer is prime time for employees to take well-deserved vacations and prime time for cyber adversaries to exploit the gaps that come with reduced office coverage, travel, and relaxed routines. 

Recent trends underscore a troubling pattern: phishing campaigns spike during summer months, social engineering attacks exploit out-of-office notifications, and employees connecting from hotels, airports, and vacation rentals introduce risks that don’t exist in the office. For federal agencies managing sensitive government data and critical infrastructure, summer cybersecurity awareness isn’t optional, it’s essential. 

Top Summer Cybersecurity Threats Facing Federal Employees 

  • Public Wi-Fi Vulnerabilities: Hotel, airport, and coffee shop networks are hunting grounds for man-in-the-middle attacks. Any federal employee accessing government systems from an unsecured network puts agency data at risk. 

  • Vacation Themed Phishing: Attackers craft convincing phishing emails around travel confirmations, rental agreements, and vacation booking updates. These campaigns see elevated click rates during summer months. 

  • Out-of-Office Information Harvesting: Automatic out-of-office replies can reveal organizational structure, project names, and backup contact details, valuable intelligence for social engineering attacks. 

  • Personal Device Risks: Employees using personal devices to “quickly check” government email or applications bypass the security controls present on agency managed devices. 

  • Reduced Monitoring Coverage: IT and cybersecurity teams are also taking vacations. Lower staffing means slower detection and response times if an incident occurs. 

Summer Cybersecurity Best Practices for Federal Employees 

Share these tips with your teams before they head out: 

  • Always use your agency’s VPN when accessing government systems from outside the office, no exceptions. 

  • Never conduct government business on public Wi-Fi without a secure VPN connection. 

  • Limit what you include in out-of-office messages. Avoid naming specific projects, colleagues, or internal systems. 

  • Use only government-issued, agency-managed devices for federal work, even on vacation. 

  • Be skeptical of any unexpected emails about travel, accommodations, or shipping, verify before clicking. 

  • Report suspicious emails immediately, even if you’re out of office. Forward to your agency’s security team. 

What IT and Security Teams Should Do Before Peak Vacation Season 

Security operations teams need to compensate for the summer coverage gap. CIG recommends the following measures for federal IT and security teams: 

  • Review and test incident response procedures with reduced staffing scenarios 

  • Ensure CDM dashboards and SIEM alerts are configured with appropriate escalation paths for vacationing staff 

  • Confirm that all remote access solutions are patched and fully functional before teams disperse 

  • Brief employees on current threat intelligence before vacation departures
