Official websites use .gov A .gov website belongs to an official government organization in the United States. Secure .gov websites use HTTPS A lock ( ) or https:// means you’ve safely connected to the .gov website. Share sensitive information only on official, secure websites. Cyberspace is particularly difficult to secure due to a number of factors: the ability of malicious actors to operate from anywhere in the world, the linkages between cyberspace and physical systems, and the difficulty of reducing vulnerabilities and consequences in complex cyber networks. Implementing safe cybersecurity best practices is important for individuals as well as organizations of all sizes. Using strong passwords, updating your software, thinking before you click on suspicious links, and turning on multi-factor authentication are the basics of what we call “cyber hygiene” and will drastically improve your online safety. These cybersecurity basics apply to both individuals and organizations. For both government and private entities, developing and implementing tailored cybersecurity plans and processes is key to protecting and maintaining business operations.
