Protecting Critical Infrastructure from Cyber Threats

The essential systems that support our daily lives – such as roads, bridges, power grids, water systems, and communication networks – have become increasingly dependent upon the Internet.

Because these systems now run on digital networks, they have also become vulnerable to cyber attacks. Cyber threats to critical infrastructure are growing more sophisticated, posing one of the most serious challenges to our national security.

As National Cyber Security Awareness Month (NCSAM) 2017 wraps up this week, we close out the month by highlighting the tie between cybersecurity and our Nation’s critical infrastructure.

Just as we all rely on critical infrastructure, we all have a role to play in keeping it safe and secure.

Individual citizens play a vital role in preventing cyber attacks on our critical infrastructure. By practicing good cybersecurity behaviors everyday – like setting strong passwords and reading privacy policies – everyone can help defend our Nation’s critical infrastructure from cyber threats.

#CyberAware Tip of the Week

One small step can make a big difference in your online security. Each week during NCSAM, we’re sharing a quick and easy tip that you can make today to better protect yourself online.

  • Keep a clean machine. Cyber criminals frequently exploit vulnerabilities in old software for their attacks, which is why it is essential to regularly update the software on your Internet-connected devices (including PCs, smartphones, and tablets) to reduce the risk of infection from viruses and malware.
