The easiest way to improve your security is to make sure your OS and other apps are updated.
As Russia continues to attack Ukraine, cybersecurity has been a concern for many. The Russian ransomware group Conti has warned nations of interfering with the invasion, and US officials blamed Russia for cyberattacks against Ukrainian websites in February.
The Cybersecurity and Infrastructure Security Agency (CISA) said while there are no specific cyber threats to the US at this time, cyberattacks can affect large and small enterprises alike, as well as home offices. One way CISA said people and businesses can protect themselves and others is by updating all devices and systems as soon as possible.
"Update the operating system on your mobile phones, tablets and laptops," CISA wrote. "And update your applications -- especially the web browsers -- on all your devices too."
Updates often patch potential security vulnerabilities, and putting off these updates could leave you and your device open to these flaws and the malicious actors out to exploit them. CISA also advised turning on automatic updates on all your devices.
Application updates can be relatively painless, especially since most manufacturers allow apps to auto-update in the background. Some people might want to wait to update their systems in case the update causes some headaches. But waiting too long to update can leave your systems vulnerable to cyber attacks.
Before you update your system, it's always a good idea to backup your data in case something goes wrong. Getting rid of bugs and patching security vulnerabilities is the goal of many updates, but sometimes things don't work out, so having a backup just in case ensures your data doesn't get lost.
