Federal Information Security Modernization Act of 2014 amends the Federal Information Security Management Act of 2002 (FISMA) to: (1) re-establish the oversight authority of the Director of the Office of Management and Budget (OMB) with respect to agency information security policies and practices, and (2) set forth authority for the Secretary of Homeland Security (DHS) to administer the implementation of such policies and practices for information systems.

Requires the Secretary to develop and oversee implementation of operational directives requiring agencies to implement the Director's standards and guidelines for safeguarding federal information and systems from a known or reasonably suspected information security threat, vulnerability, or risk. Authorizes the Director to revise or repeal operational directives that are not in accordance with the Director's policies.

Requires the Secretary (currently, the Director) to ensure the operation of the federal information security incident center (FISIC).

Directs the Secretary to administer procedures to deploy technology, upon request by an agency, to assist the agency to continuously diagnose and mitigate against cyber threats and vulnerabilities.

Requires the Director's annual report to Congress regarding the effectiveness of information security policies to assess agency compliance with OMB data breach notification procedures.

Provides for OMB's information security authorities to be delegated to the Director of National Intelligence (DNI) for certain systems operated by an element of the intelligence community.

Directs the Secretary to consult with and consider guidance developed by the National Institute of Standards and Technology (NIST) to ensure that operational directives do not conflict with NIST information security standards.

Directs agency heads to ensure that: (1) information security management processes are integrated with budgetary planning; (2) senior agency officials, including chief information officers, carry out their information security responsibilities; and (3) all personnel are held accountable for complying with the agency-wide information security program.
