(Security) network protocols that every homeowner should be aware of is quite a difficult topic to answer in a couple of lines. Mostly because most homeowners are not computer/software specialists nor have an understanding of cryptography and various security issues.
That however isn’t an excuse for forgetting about security and ignoring best practices. There are many technologies that are often used in the name of security: TLS/SSL and VPNs to name a few. But just because these terms are thrown around, doesn’t mean that something is “secure”. Just like one would not consider locking your front door and leaving the window open as “secure”.
When implementing network security, it is best to get a professional to install all the “locks” and setup everything to best security practices.
But at the end of the day, we still have to make sure not to leave the window open when leaving the house – good security hygiene is crucial to staying secure:
1. Not reusing or sharing passwords
2. Using strong passwords and ideally a password manager
3. Not opening suspicious email attachments or visiting suspicious links
4. Not inserting unknown accessories (e.g. USB flash drives) into your computers/networks
5. Using TLS/SSL where possible (the S in HTTPS is for the TLS/SSL version of the HTTP protocol)
6. Enabling WiFi security; WPA2 or WPA3
7. Password protect services even if it is not required and change default passwords
