Protecting Against Malicious Code
To prevent viruses and the download of malicious code:
Scan all external files before uploading to your computer
For personally-owned devices, research any application and its vulnerabilities before downloading that “app”
For Government-owned devices, use approved and authorized applications only
Mobile code can be malicious code. To prevent damage from malicious mobile code:
Only allow mobile code from your organization or your organization’s trusted sites to run
Contact your security Point of Contact (POC) or help desk for assistance, especially with e-mails that request personal information
To prevent the downloading of viruses and other malicious code when checking your e-mail:
View e-mail in plain text and don’t view e-mail in Preview Pane
Use caution when opening e-mail: Look for digital signatures if your organization uses them. Digitally signed e-mails are more secure.
Scan all attachments
If authenticity cannot be confirmed, delete e-mail from senders you do not know
Don’t e-mail infected files to anyone
Don’t access website links, buttons, and/or graphics in an e-mail or a popup generated by an e-mail message
