This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
Threat Modeling with STRIDE drafts a note for a feature you administer. Write the abuse you worry about in plain words, the control you already have, and the gap. Do not add steps that would carry the abuse out.
Write the system you administer, the name of this change, and the time. A second change waits until this line has been read back.
The browser tool drafts text or reads a paste you already hold. It does not log in, it does not scan a network you do not administer, and it does not apply.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the system named in the ticket. Read the draft, then the system, then decide.
Rollback is the file, the record, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.
- Write the feature you administer.
- Write one worry and one control.
- Leave out any steps that carry it out.
- Stop.
Mistakes that outlive the statement
Threat Modeling with STRIDE goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- Attack steps in the model.
- A system you do not administer.
- A gap marked as already fixed.
Decisions to write down
One decision for Threat Modeling with STRIDE: The feature is yours. The page is a model. No attack steps are included. The gap stays a gap. And one worry is enough.
Checks before you call it done
Confirm this before you call the change done: The feature is written. No attack steps are in the note. The control is named. The gap is written. And a second person can say the worry. If one of those fails, stop.
# Threat model. Not attack steps.
Before you leave the system
Threat Modeling with STRIDE ends when the system in the note is the system in the ticket. If it is not, stop.
The draft stays a draft until a person has read the names in it. A generator does not log in, does not scan, and does not send mail.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you publish because a draft included them.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save. A sample password is replaced. It is not a password you keep.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the scope aloud. If they cannot find it in the ticket, the note is not done.
This page is a planning guide. It is not legal advice, not an audit opinion, not a vendor manual, and not the text of a standard. You do not disable a security control to make a check pass. You do not use the page against a system you do not administer.
