USPS wants employees and managers to remain vigilant and exercise caution when sharing postal information online with other organizations.
It’s often necessary to send information to “third-party partners” that work with the Postal Service to support its operations.
If one of these organizations experiences a cyberthreat, USPS could be affected, too.
To reduce such risks, the CyberSafe at USPS team offers these tips:
• Share only need-to-know data. Send information to third parties only when a data handling agreement is in place.
• Protect your inbox. All emails from external or non-USPS senders display [EXTERNAL] in the subject line. Report suspicious emails by selecting the “Report to CyberSafe” button in Outlook.
• Send emails safely. When authorized to share sensitive information with third parties, use #sensitive# in the subject line.
• Transfer large files securely. Use the Secure Large File Transfer application to send these files to third parties.
• Separate for security. Plug only USPS-approved devices into the postal network.
To report a cybersecurity incident, call 866-877-7247 or send an email to CyberSafe@usps.gov.
