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
The checker reads response headers. A missing header is a line in the ticket, not a bypass you try. You do not weaken a content policy during the reading.
One site you administer. The browser tool does not log in.
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. It is not a password you keep.
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.
- Name the site.
- Read the header list.
- Write the one header the ticket will add later.
- Do not remove a header.
- Stop.
Mistakes that outlive the statement
HTTP Security Headers Guide goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A header removed to silence a warning.
- A policy weakened during the reading.
- A site you do not administer.
Decisions to write down
One decision for HTTP Security Headers Guide: The site is yours. No header was removed. And the next change has its own window.
Checks before you call it done
Confirm this before you call the change done: The site is written. The list was read. No header was removed. Nothing was deployed. And the site is yours. If one of those fails, stop.
# Read headers. Do not remove one to pass a test.
# 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. It is not a password you keep.Before you leave the system
HTTP Security Headers Guide 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.
