 ### Managing security issues
 
-Security issues should ideally be reported through the processes outlined in
-[SECURITY.md][security reporting]. This allows the collaborators to
-appropriately triage the report and address vulnerabilities in a planned
-security release. If an issue is opened in the public repo
-which describes a security issue, or if an issue is later identified to be
-describing a security issue, take the following steps:
-
-* Ask the originator to submit a report through Hacker one as outlined in
-  [SECURITY.md][security reporting].
+Use the process outlined in [SECURITY.md][] to report security
+issues. If a user opens a security issue in the public repository:
+
+* Ask the user to submit a report through HackerOne as outlined in
+  [SECURITY.md][].
 * Move the issue to the private repo called
   [premature-disclosures](https://github.com/nodejs/premature-disclosures).
 * For any related pull requests, create an associated issue in the
   `premature-disclosures` repository.  Add a copy of the patch for the
   pull request to the issue. Add screenshots of discussion from the pull request
   to the issue.
-* Open a ticket with GitHub asking that the pull requests be deleted through
-  [GitHub support](https://support.github.com/contact)
-  using Node.js(team) as the account organization.
-* Open a new issue in the repository in which the issue was originally
-  reported with a brief FYI to the originator: "FYI @xxxx we asked GitHub
-  to delete your pull request while we work on releases in private." with the
-  title `FYI - pull request deleted #YYYY`.
-* Email `tsc@iojs.org` with the link to the issues in the
-  `premature-disclosures` repo so that the TSC is aware that they
-  may need to expedite handling of the issue due to premature
-  disclosure.
