How do I improve the security of my home network?
Use strong and unique passwords.
Run up-to-date antivirus software.
Install a network firewall.
Change default log-in passwords and usernames.
Leaving these unchanged creates opportunities for malicious cyber actors to gain unauthorized access to information, install malicious software, and cause other problems.
Most network devices are pre-configured with default administrator passwords to simplify setup. These default credentials are not secure—they may be readily available on the internet, or may even be physically labeled on the device itself.
Install firewalls on network devices.
Adjust factory-default configurations on software and hardware.
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.
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.
Regularly back up your data.
Remove unnecessary services and software.
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.
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.
Increase wireless security.
Update your software regularly.
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
Besides adding new features and functionality, software updates often include critical patches and security fixes for newly discovered threats and vulnerabilities
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.
Mitigate Email Threats.
What is home network security and why should I care?
Many home users share two common misconceptions about the security of their networks:
Their home network is too small to be at risk of a cyberattack.
Their devices are “secure enough” right out of the box.
Most attacks are not personal in nature and can occur on any type of network—big or small, home or business. If a network connects to the internet, it is inherently more vulnerable and susceptible to outside threats.
Refers to the devices connective network protection —such as routers, computers, smartphones, and Wi-Fi-enabled baby monitors and cameras—to each other and to the internet within a home.
