Security Sector Reform

How post-conflict and transitional states rebuild their security institutions, and why effective reform is essential for lasting peace.

What Is Security Sector Reform?

Security sector reform (SSR) is the process of transforming a country's security institutions, including the military, police, intelligence services, judiciary, and corrections system, to make them effective, accountable, and respectful of human rights. SSR is particularly critical in post-conflict states where security forces were part of the problem: armies that committed atrocities, police that served a dictator, or intelligence agencies that surveilled and repressed citizens.

The concept emerged in the late 1990s from the recognition that development and security are inseparable. A country cannot attract investment, deliver public services, or build democratic institutions if its security forces are corrupt, predatory, or unaccountable. The UK's Department for International Development was an early champion, followed by the OECD, the African Union, and the United Nations, which published its first SSR guidelines in 2008.
