Updating firmware on router
You’ll often be able to find the firmware-updating information under “Firmware Upgrade,” “Software,” “System Update,” “Router Upgrade,” or a similarly named option.Depending on your router, you may have to do this by hand, set up automatic updates — or not do anything at all.Your router runs a “firmware,” which is essentially its operating system.Your router essentially functions as a firewall, shielding your other devices from inbound connections by keeping them all to itself.But, by design, your router is the one point in your home network that’s exposed directly to the Internet.Quite a few routers are actually built on top of Linux, and that means security vulnerabilities in the Linux kernel or related software — like the Shellshock bug in the Bash shell — could affect your router.Problems can also occur due to poor router firmware design in general, such as the backdoors that have been discovered in routers produced by Linksys, Netgear, and other massive companies.Home routers are particularly vulnerable because they’re exposed directly to the Internet.
Depending on your router, you may have to install these yourself.To install firmware updates, you’ll need to access yhour router’s web interface in a web browser.Keeping your home router updated is a crucial part of staying secure.Shellshock affected a number of routers, and we’ve also seen routers hacked and turned into botnets. You should ensure your router is getting security updates, too.
As any attacker could contact your router, it’s crucial your router is secure.
Manufacturers release new versions of the software for your router, just as they do for the software on your computer, phone, tablet, game console, and other devices.
