It is becoming increasingly popular for attackers to compromise computers through vulnerable web browsers. An insecure web browser can lead to spyware being installed on your computer without your knowledge, attackers taking control of your computer, stealing your information, or even using your computer to attack other computers.
The set-up configuration for many web browsers is not secure by default. The following steps will help make your web browser more secure. These settings are especially important if you use your browser to access, send or receive sensitive information.
- Keep your browsers up to date
- Enable automatic updates for your browser
- Block pop-ups, plug-ins, and phishing sites
- Set your browser not to store passwords.
- Disable third-party cookies
- Browser-specific settings:
- Firefox: install the uBlock Origin add-on
- Safari: disable Java
- Edge: set up security zones
- Chrome: Top Right, click 'More'. Click Update Google Chrome. If you don't see this button, you're on the latest version.
Important note: While making your browser more secure helps reduce the risk that someone will be able to use it to compromise your computer, it is still important to have safe computing habits so attackers get fewer chances to try. Don't click on unknown or unsolicited links or open unexpected attachments. Hackers are more sophisticated than ever, trying to make themselves appear as someone among your contacts or even within your organization. Don't download files, programs or tools unless you are able to confirm that they are from someone you trust and you are positive they are safe.
