Organisation for Economic Co-operation and Development (OECD) has defined four standards that SSR should strive for:1. Establishment of effective governance, oversight and accountability in the security system; 2) improved delivery of security and justice services; 3) development of local leadership and ownership of the reform process; and 4) sustainability of justice and security service delivery.The target of SSR are the components of the state that uphold national security. Although the security sector is therefore a wide term open to interpretation, it is generally used to describe the structures, institutions and personnel responsible for the management, provision and oversight of security in a certain country. Therefore, the scope and target of SSR has usually been defined comprising the following four groups: Core security actors, such as armed forces, police, gendarmerie, border guards, customs and immigration, and intelligence and security services; security management and oversight bodies, such as ministries of defence and internal affairs, financial management bodies and public complaints commissions; justice and law enforcement institutions, such as the judiciary, prisons, prosecution services, traditional justice systems; and non-statutory security forces, such as private security companies, guerrilla armies and private militia. Objective To observe and measure the quality of SSG as well as set more definite objectives, international development actors generally break down good security sector governance into different principles that are believed to showcase different subparts of a healthy security sector under democratic control. While exact configurations vary, some of the most common principles or objectives of good SSG that are commonly used include accountability, rule of law, and effectiveness. A multitude of different practical situations of good SSG exist according to development actors: For example, in a security sector lead by good governance, the use of force is defined by a legal framework. This subsequently requires, among others, that publicly transparent laws are in place; oversight and separation of powers mechanisms are established and working; and the state's legitimate use of force is regulated through strategies and policies. An operational level example would be improved and open interaction between the public and the security sector, including functioning freedom of information and complaint institutes. SSR is aimed at the existence of both national security and human security. However, the goals of providing national and human security can be conflictual in the context of conflict-torn societies which lack the framework of democratic governance. According to Florian Weigand, the experiences of SSR in Afghanistan,
