Certification is carried out by independent, accredited certification body. Businesses that are seeking independent certification of their ISMS (Information Security Management System) should always go to an accredited certification body, such as the International Organization for Standardization.
The International Organization for Standardization (ISO) has developed a new series of security standards, the rest of which is ISO 27001. ISO 27001 is the replacement for British Standard 7799. Additional International Organization for Standardization in the 27000 family includes IS (27003, covering security guidance; ISO 2700, for measurements: and ISO 27005, covering risk. However, claims of obtaining ISO 27001 certification are often misinterpreted, or used as a guarantee where they should not be. The expectation of certification is that its implementation will be in the hands of qualified people. Many certification bodies offer ISO 27001 lead audit training classes.
ISO 27001 describes how to build what ISO calls ISMS. If an ISMS is developed on a standard of acceptance or rejection of the assessed risk, and using 3rd party certification to provide outside verification of the level of assurance, is an excellent tool and will create a management system for information security.
Why Certify against ISO 27001?
No government codes or regulations require ISO certification, so why bother? ISO certification can support business and marketing goals of the company. It is becoming increasingly common for ISO 27001 certification to be a pre-requisite in service specification procurement documents and, as buyers become more sophisticated in their understanding of the ISO 27001 approved certification scheme, so they will increasing set out their requirements are specifically, not only in respect to the scope of the certification and the level of assurance they require.
This rapid maturing in the understanding of buyers, as they seek greater assurance from the accredited certification to ISO 27001, is driving organizations to improve the quality of their ISMS and, by definition, to improve the granularity and accuracy of their risk assessments.
Certification is applying a discipline to information security to be better at planning, implementing, and maintaining information security and achieving a highly effective information security program that enables a business to achieve ISO 27001 certification. An external certification auditor should be assessing the ISMS against the published standard, not against the advice of a scheme manager, a consultant or any third party. It is critical that those responsible for the ISMS should be able to refer explicitly to its clauses and intent and be able to defend any implementation steps they have taken against the Standard itself. Outside certification is absolutely needed for any ISO certification . It gives management an initial and ongoing targeting to aim for and ensures that the organization has effectively implemented the standard.
To ensure integrity is to guard against unauthorized directives or destruction of information. Integrity ensures a safeguard against undesired outside access. Availability ensures information is ready to use. A loss of availability is the disruption of access to or use of information or an information technology. The three cornerstones of information protection are confidentiality, integrity, and availability.
To ensure a proper security plan, business should focus on three cornerstones of security; they are confidentiality, integrity, and availability. How can an organization manage information security and maintain the three cornerstones of security? One answer is to implement an ISMS and use the ISO standards as a guide to develop an effective ISMS. Plan-Do-Check-Act (PDCA) provides an effective ISMS and the ISO 27001 process providing the guidance on the implementation of a ISMS by adhering to the PDCA process.
