No home computing setup is complete without a router – that little device that helps shuttle information between the Internet and the computers, mobile phones, and other devices connected to your home network. It is important to note, though, that routers are just as susceptible to security flaws and malware as the computers connected to them.
Case in point: security researchers have recently discovered a series of flaws in some older D-Link routers that could allow malicious users to intercept data as it travels through an affected device. The affected models include: DWR-111, DWR-116, DWR-140L, DWR-512, DWR-640L, DWR-712, DWR-912, and DWR-921. If your home network includes one of these models, consider upgrading to a newer router.
For more information about these router issues, see Serious D-Link router security flaws may never be patched on the Sophos security page.
ITS recommends that you always apply available security updates and firmware patches to your router, as well as any other computers or devices on your home network. If your devices’ manufacturers no longer provide updates for your particular models, as is the case with many of the models noted above, you should consider replacing them with newer, more secure devices.
