Update your software!

Bad actors will exploit flaws in the system. Network defenders are working hard to fix them as soon as they can, but their work relies on all of us updating our software with their latest fixes. We recommend the following:

  • Update the operating system on your mobile phones, tablets, and laptop
  • Update your applications – especially web browsers – on all your devices
  • Turn on automatic updates for all devices, applications, and operating systems

What are patches?

Patches are software, and operating system (OS) updates that address security vulnerabilities within a program or product. Software vendors may choose to release updates to fix performance bugs and provide enhanced security features.

How do you find out what software updates you need to install?

When software updates become available, vendors usually put them on their websites for users to download. Install updates as soon as possible to protect your computer, phone, or other digital devices against attackers who want to take advantage of system vulnerabilities. Attackers may target vulnerabilities for months or even years after updates are available.

Some software will automatically check for updates, and many vendors offer users the option to receive updates automatically. If automatic options are available, the Cybersecurity and Infrastructure Security Agency (CISA) recommends that you take advantage of them. If they are not available, periodically check your vendor’s websites for updates.

Make sure that you only download software updates from trusted vendor websites. Do not trust a link in an email message—attackers have used email messages to direct users to websites hosting malicious files disguised as legitimate updates. Users should also be suspicious of email messages that claim to have a software update file attached. These attachments may contain malware (see Using Caution with Email Attachments for more information).

If possible, only apply automatic updates from trusted network locations (e.g., home, work). Avoid updating software (automatically or manually) while connected to untrusted networks (e.g., airports, hotels, coffee shops). If updates must be installed over an untrusted network, use a Virtual Private Network connection to a trusted network and apply updates.

What is the difference between manual and automatic updates?

Users can manually install updates or elect their software programs to update automatically.

  • Manual updates require the user or administrator to visit the vendor’s website to download and install software files.
  • Automatic updates require the user or the administrator’s consent when installing or configuring the software. Once you consent to automatic updates, software updates are “pushed” (or installed) to your system automatically.

Note: Some applications require older versions of the operating system (OS). If you have a unique application, check with the developer before updating the OS.
