Pl rate-

Least Privilege:

In my house, I am the only one that has the right to install new software. To reduce the likelihood of anyone installing anything that is malicious I require that they ask me to install it. Everyone in the house runs as a normal user with reduced privileges, including me. I only use the admin account to install new software or problem solve more complicated issues.

Process Isolation:

Day to day browsing on the web is never done on my primary work computer. I do casual browsing on the web on a tablet that I make sure to keep up to date on patches. This allow me to keep my primary work computer away from the majority of harmful and infected web sites I may accidentally visit keeping my more valuable information isolated.

Granularity of Access:

I do not have admin privileges on my day to day account to reduce the likelihood that I accidentally install something myself or come across something that uses a zero-day vulnerability.

Abstraction:

My wife teaches meditation and frequently records audio to post on her web site or send to clients. I have helped her by processing the audio to make it sound better and more professional. This involves a lot of audio manipulation and settings. Sometimes she need it quicker or I might not be around so I have created a script that does most of this for her. This abstracts the complicated settings making it easy for her to run the audio through.
