What is ISO 27001?
ISO 27001 is an international standard published by the International Standardization Organization (ISO) that provide a specification for an information security management system (ISMS). ISMS a managed framework for the protection of business-critical information. It contains a set of policies, procedures, and controls for protecting confidentially, integrity and availability of the information. It is a systematic approach consisting of people, process, a technology that helps to protect and manage all the organization information through risk management. ISO 27001 standard is being designed to help organize, manage their security practices consistently and cost-effectively. This is applicable to all organization, irrespective of their size, type or nature. To know more about ISO 27001, you can visit here.
The main focus of ISO 27001 is to protect three aspects of information i.e. confidentiality, integrity and availability. This is done by finding out what potential problems could happen to the information (i.e. risk assessment), and then defining what needs to be done to protect such problems from happening (i.e., risk mitigation or risk treatment). The main philosophy of ISO 27001 is based on managing risks i.e. finding out the risks and systematically treat them.
- Confidentiality: Information is not available or disclosed to unauthorized people, entities or processes.
- Integrity: Information is complete and accurate and protected from corruption.
- Availability: Information is accessible and usable as and when authorized users require it.
Why ISO 27001 Certification is Important?
There are many techniques available to protect the information technology industry i.e antivirus, firewalls, backups, etc. With these types of security elements, there are still chances of the data breaches. Technology on its own is not enough to protect confidential data. Therefore, business needs more practical means of safeguarding information.
Who Needs ISO 27001 Certification?
The business of all sizes should need an ISO certification since a data breach can also happen to the business that collects, processes and stores customer information. Therefore, any business working with customer records should consider learning more about ISO 27001 certification.
