ISO 27001 definition
ISO 27001 (formally known as ISO/IEC 27001:2005) is a specification for an information security management system (ISMS). An ISMS is a framework of policies and procedures that includes all legal, physical and technical controls involved in an organisation’s information risk management processes.
Why is ISO 27001 important?
Not only does the standard provide companies with the necessary know-how for protecting their most valuable information, but a company can also get certified against ISO 27001 and, in this way, prove to its customers and partners that it safeguards their data.
Individuals can also get ISO 27001-certified by attending a course and passing the exam and, in this way, prove their skills to potential employers.
Because it is an international standard, ISO 27001 is easily recognized all around the world, increasing business opportunities for organizations and professionals.
What are the 3 ISMS security objectives?
The basic goal of ISO 27001 is to protect three aspects of information:
- Confidentiality: only the authorized persons have the right to access information.
- Integrity: only the authorized persons can change the information.
- Availability: the information must be accessible to authorized persons whenever it is needed.
