If you’re connecting to the internet at home, then you should be taking a range of precautions to protect yourself from the attention of malicious online actors. What might seem like a trivial mistake can sometimes be exploited to create a big problem. What’s more, many of the habits and practices that create vulnerabilities are distressingly common.
The good news is that most of them are cheap or free to fix, and none require technical expertise. Let’s run through a few common errors, and how they might lead to disaster.
Weak or Reused Passwords
If your password can be easily broken by a human being or a brute-force algorithm, then the service associated with it can be easily compromised. If you reuse a single password against many different services, then a compromise in one area might lead to other parts of your digital life being compromised. Attackers know this, and routinely try credentials leaked from one breach against banking, email, and shopping accounts elsewhere.
Passwords should be strong and unique. Use a good password manager package to create and store yours. This will ensure not only that you don’t have to spend time composing a password for each service you use, but also that you’ll be able to easily store and recall them.
One reused password can turn a single data breach into a problem across every account you own.
Length matters more than cleverness. A long passphrase made of several unrelated words is usually stronger, and easier to remember, than a short string of symbols, and aiming for at least 15 characters where a site allows it is a good benchmark. Protect the password manager itself with a strong master passphrase and MFA. Your email account deserves the strongest password of all, since it is often the key used to reset every other login.
Ignoring Software and Firmware Updates
Software is rarely perfect. Over time, hackers might discover exploits and vulnerabilities, and thereby compromise the software in question. This might, in some cases, expose your devices and data.
The way to deal with this is through regular updates. This matters especially when we’re talking about operating systems and router firmware. Set up automatic updates, so that you don’t have to worry about doing this manually.
Additional software might provide additional security. For example, a free VPN for Windows might allow you to connect via a secure, encrypted tunnel.
A VPN is a useful layer, but it is only one layer. It protects the traffic traveling between your device and the VPN server; it does not fix a weak password, remove malware, or stop you from handing credentials to a fake login page. Updates, unique passwords, MFA, and phishing awareness come first; a VPN is an optional privacy tool on top of them, not a substitute. According to CISA’s guidance on software updates, the habit worth building is to install updates promptly, especially for web browsers and security software, rather than clicking “remind me later,” bec
