I am starting to take on more and more enterprise clients while working remotely

Question

I am starting to take on more and more enterprise clients while working remotely from my home office. I have a pretty secure network at the moment, but I have a lot hardware that I am not using and should be. I am a programmer, not a network specialist, so I would like to reach out and ask for some advice on how to make best use of the hardware I have at hand.

My hardware: Linksys 17351 CISCO model 1721 series router with CISCO 1 Port 10BT Ethernet WAN Interface card and the router my internet connection came with, Arris DG860/TG862 with firmware 7.5.63C

I currently have about 5 wireless devices that I use, and they are currently setup via a MAC whitelist. I use WPA2 TKIP/AES security with WPS disabled.

Any advice would be appreciated.

Explanation / Answer

Beside what you have already done disabling WPS and using whitelisting:

Use the latest firmware

Disable TKIP, just use AES.

Obviously... change default login / wifi credentials. Use a decent password.

Disable UPnP.

Firewall policies to DROP, only allowing what you are going to use (80,443,22,53,3389...).

Limit the amount of DHCP devices, also set them to expire every 24h.

But also remember that securing a home network is not just secure the networking devices. Harden your systems, configure the host-based firewall, always install updates, etc.
