I will be moving a new location in a short time, which means all of my devices will be coming with me.
My landlord is the kind of older person who needs help connecting to WiFi. Despite this, she manages to use a number of devices which connect to the internet: TV, phone, Kindle, computer, tablet... When I recently talked to her, it became evident that she did not understand the risks of clicking links in her many questionable emails. Naturally, she's happy to put me in charge of making sure everything works (but that's another discussion...).
In the interest of my own devices, what general first steps are advisable to take to secure this unfamiliar network, which could have any number of undetected threats? I'm planning on changing passwords, installing antivirus, and probably subscribing to a VPN service, but I'd like to specifically take measures to
- Determine (as best as possible) that nothing malicious is already residing on the network.
- Reduce the risk that actions taken by my landlord lead to other devices the network being infected.
