Mobile devices such as smartphones, laptops, and tablets help employees stay productive and connected wherever work takes them. However, the same convenience that makes these devices valuable also makes them attractive targets for cybercriminals.
Threats such as smishing attacks, malicious applications, fake QR codes, and unsecured public Wi-Fi networks continue to increase. A compromised mobile device can expose sensitive information and create risks for Postal Service™ operations.
Employees who use USPS-issued mobile devices must follow these cybersecurity best practices:
n Keep your device updated with the latest operating system and security patches.
n Use a strong PIN and password to lock your device.
n Be cautious of unexpected text messages, emails, QR codes, and links requesting personal or work-related information.
n Avoid conducting USPS® business on public Wi-Fi networks. Use your smartphone‘s hotspot or a virtual private network when available.
n Immediately report lost or stolen USPS devices.
n Avoid conducting personal tasks on USPS mobile devices. Keep personal apps and data separate from USPS apps and data.
Maintaining mobile device security is an important part of protecting Postal Service information and systems.
