How do I improve the security of my home network?

By following some of the simple but effective mitigation techniques below, you can significantly reduce the attack surface of your home network and make it more difficult for a malicious cyber actor to launch a successful attack.

  • Update your software regularly. Regular software updates are one of the most effective steps you can take to improve the overall cybersecurity posture of your home networks and systems. Besides adding new features and functionality, software updates often include critical patches and security fixes for newly discovered threats and vulnerabilities. Most modern software applications will automatically check for newly released updates. If automated updates are not available, consider purchasing a software program that identifies and centrally manages all installed software updates. 
  • Remove unnecessary services and software. Disable all unnecessary services to reduce the attack surface of your network and devices, including your router. Unused or unwanted services and software can create security holes on a device’s system, which could lead to an increased attack surface of your network environment. This is especially true with new computer systems on which vendors will often pre-install a large number of trial software and applications—referred to as “bloatware”—that users may not find useful. The Cybersecurity and Infrastructure Security Agency (CISA) recommends that you research and remove any software or services that are not being used regularly.
  • Adjust factory-default configurations on software and hardware. Many software and hardware products come “out of the box” with overly permissive factory-default configurations intended to make them user-friendly and reduce the troubleshooting time for customer service. Unfortunately, these default configurations are not geared towards security. Leaving them enabled after the installation may create more avenues for an attacker to exploit. Users should take steps to harden the default configuration parameters to reduce vulnerabilities and protect against intrusions.
