also called site security
The practices protecting a site, accounts and data from compromise.
Keeping people out of things they should not reach.
What It Is
Security is a Technology item. Stated plainly: the practices protecting a site, accounts and data from compromise.
It is an idea you reason with rather than a deliverable you hand over, so two teams can both hold it correctly and still apply it differently. Once it is defined that clearly, arguments about it usually stop.
How It's Used
In practice, Security shows up in build decisions, tooling and the plumbing behind a working system. It normally appears alongside SSL, Two-Factor Authentication and Access Control. The practical test is whether a decision changes because of it.
Why It Matters
Security is one of those items that only becomes visible when it is missing. When it is unclear, small technical debts compound into a rebuild. Clarity here removes a surprising amount of downstream argument.
Think of it as a lens. Look through it and some choices get obvious. Keeping people out of things they should not reach.
Termshift™
How the meaning shifts depending on who is using it, and where.
Professionally, Security carries the narrow meaning: the practices protecting a site, accounts and data from compromise.
Explained to someone with no marketing background, Security is keeping people out of things they should not reach.
The Bottom Line
If you only keep one thing about Security: keeping people out of things they should not reach. Everything after that is detail.
