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
Content Security Policy Explained drafts a header and can evaluate one you paste. A policy that allows inline script to silence an error is a line you delete. Do not publish the header during the reading.
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 site you administer.
- Read the draft or the paste.
- Delete unsafe-inline and unsafe-eval unless a person has written why they remain.
- Do not publish.
- Stop.
Mistakes that outlive the statement
Content Security Policy Explained goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- unsafe-inline added to make a test pass.
- The header published during the reading.
- A site you do not administer.
Decisions to write down
One decision for Content Security Policy Explained: The site is yours. Inline exceptions are absent or justified in writing. Nothing is published. One policy is the window. And the evaluator does not change the site.
Checks before you call it done
Confirm this before you call the change done: The site is written. The draft was read. Nothing was published. unsafe-inline is absent or written down. And a second person can say the policy. If one of those fails, stop.
# CSP draft. Do not publish.
# Do not add unsafe-inline or unsafe-eval to make a page pass.
Before you leave the system
Content Security Policy Explained 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.
