Give Your Accounts More Than One Line of Defense.

Passwords are important—but they shouldn’t have to do all the work.

Using strong, unique passwords and enabling multi-factor authentication (MFA) wherever available can add important layers of protection to your accounts.

Remember:
✅ Avoid reusing passwords across accounts.
✅ Use long, unique passwords or passphrases.
✅ Use an approved password manager when appropriate.
✅ Enable MFA whenever it is available.

One compromised password shouldn’t provide easy access to everything else. Small security habits can make a big difference.

Don’t make it easy for them.

🔐 Staying informed is an important part of maintaining a strong security program.

The Defense Counterintelligence and Security Agency (DCSA) has released its FY26 Annual Report, highlighting current counterintelligence trends and the evolving threats facing cleared industry.

For organizations supporting the defense industrial base, reports like this are a valuable reminder of the importance of continued awareness, timely reporting, and a strong security culture.
