4) What is accreditation and certification?
An accreditation body is an organization (usually a national one) which grants third parties the authority to issue 'certificates' (to certify) against standards. This third party is the certification company, which actually certifies against the standard. Examples include: BSI, JACO IS, KEMA, KPMG, SFS-Sertifiointi Oy, SGS, STQC, SAI Global Limited, UIMCert GmbH.

5) How should security REQUIREMENTS be established? ISO 17799 identifies three main sources:
- "The first source is derived from assessing risks to the organization. Through risk assessment threats to assets are identified, vulnerability to and likelihood of occurrence is evaluated and potential impact is estimated"
- "The second source is the legal, statutory
, regulatory and contractual requirements that an organization, its trading partners, contractors and service providers have to satisfy" - "The third source is the particular set of principles, objectives and requirements for information processing that an organization has developed to support its operations".
