Celebrate all you want, it's still nearly 3 months before he is inaugurated. Until he is the President, he has no authority.
You're incorrect in that. Under the provisions of the Presidential Transitions Act of 1963 (amended 2000), the President-elect is entitled to the same Presidential Daily Briefings by the intelligence agencies that the sitting President receives.
Just as a funfact, it was at one of these PDBs during the transition from the Clinton to the Bush White House that then-Security Adviser Rice was told by Secretary of State Christopher that al-Queda and Osama bin Ladin would become major foreign policy issues to the new administration.
Furthermore, under the Transition Act, the President-elect may draw on the services of the Government Accountability Office and the General Services Administration to appoint their to-be White House Staff members and entitle them to the security clearances those offices entail.
