There is no need for and to co-exist, as one is just the abbreviation of the other. For some reason, I can't make a synonym of , stating I don't have enough reputation.

    Agree! Both about the synonym, and keeping the long as the main tag.

I have merged csp into content-security-policy and set the synonym.

Aside: this can be done without moderator intervention via enough upvotes on a tag synonym.

    For some reason, I was not able to create the synonym, even though I had points in content-security-policy. But I am glad this is resolved now.

While I agree that in the world of web appsec, CSP == Content Security Policy, I'm not sure that's true in all areas of information security.

Taking a look at the wikipedia disambiguation page for CSP, the following jump out as potential legitimate uses of "CSP" on this site:

  • Credential Service Provider -- seems to be a US Gov term for an authority who issues any kind of e-credentials.
  • Critical Security Parameter -- Defined in FIPS 140-2 as "Critical security parameter (CSP): security-related information (e.g., secret and private cryptographic keys,and authentication data such as passwords and PINs) whose disclosure or modification can compromise the security of a cryptographic module."
  • Cryptographic Service Provider -- A Microsoft Windows term for CAPI-like plugins.
  • Cloud Service Provider -- synonym for Cloud Computing.

    That's true, and I understand the potential hazards. Should it turn out to be a problem, we'll have to retag and deprecate csp. We used to have a similar problem, where people used the tag policy on content security policies all the time.
