The Postal Service wants employees and contractors to use secure, encrypted channels when communicating on USPS-issued mobile devices.
Instead of using a device’s phone or text message features, the organization recommends employees and contractors use features such as iMessage, Teams Call, Teams Chat, Zoom Call or Zoom Chat.
When connecting to Teams or Zoom meetings, the Postal Service recommends employees and contractors use each application’s audio feature rather than the “call me” or “dial in” functions.
The USPS information security team issued this recommendation as part of its ongoing efforts to monitor the cybersecurity landscape and protect the organization from threats.
