A model for establishing, implementing, running, overseeing, reviewing, maintaining, and upgrading an information security management system is provided by the international standard ISO 27001 (ISMS). The management standard ISO 27001 is suitable for all areas of business and industry and is not just for computerized electronic data. The purpose of ISO 27001 Certification and information security, contrary to popular belief, is not restricted to preventing unauthorized access to computers and networks
On the other hand, any organization that deals with the protection of information, regardless of its form, can use the ISO 27001 Information Security Management System standard. A law business, for instance, manages a large amount of data, mostly private data. As a result, a legal company owes it to its clients to safeguard that information and maintain its confidentiality. The aforementioned law firm can guarantee the privacy of its clients’ information by putting ISO 27001 controls in place.
All information, whether it is spoken, shown in video or audio, printed, stored electronically, spoken, or sent through email, is covered by ISO 27001 concerning security. No matter how information is exchanged, stored, or transported, ISO 27001 ensures it is always safeguarded appropriately.
Information security involves preserving:
Confidentiality: Information and assets are kept private and are not made available to unapproved people, groups, or systems.
Integrity: The maintenance of the truthfulness and comprehensiveness of data and resources.
Availability: Information and resources are available and useful upon request by a recognized person, group, or procedure.
Implementing mitigating controls that address dangers is part of protecting information and assets. Threats are evaluated by ISO 27001 based on:
Probability: The chance that an event will happen.
Impact: The extent of the event’s disturbance to the particular asset.
Multiple controls and control objectives are included in the ISO 27001 Standard to guarantee information security to the qualities (confidentiality, integrity, and availability). These consist of:
- A security policy should give organizational direction and information security provisions while taking into account corporate objectives, requirements, and legal and regulatory constraints.
- Information security is organized according to goals, rules, and procedures that control it.
- Asset classification involves identifying and protecting assets effectively.
- Information that workers, independent contractors, and other parties are exposed to is dealt with in personnel security (see our blogs on Prior, During, and After Employment).
- Controls that prevent the loss, damage, theft, or compromise of assets and organizational activities as well as illegal physical access to, alteration of, or interference with, a company’s facilities and information.
- Focusing on guaranteeing accurate and secure operation of information, communications, and operation management includes third parties, systems, software, backups, networks, media, information exchange, e-commerce, and monitoring.
- Access Control focuses on regulating the level of access with the administration of rights, duties, and application data.
- Information security is a crucial element of information technology and information systems, and system development and maintenance make sure of this.
- By ensuring that information security incidents, flaws, and vulnerabilities relating to information systems are reported and addressed promptly, incident management ensures that corrective action can be taken.
- Business continuity management is the process of developing, testing, and putting into action plans to prevent business activity disruptions and safeguard crucial business processes.
- Observing laws, rules, and contractual responsibilities requires compliance, which is achieved through audits and reviews.
The Importance of ISO 27001 Information Security
Customer data, credit card information, intellectual property, and other types of organizational information are all regarded as essential assets for firms. Organizations can maintain a competitive advantage, cost-effectiveness, a stable cash flow, profitability, legal compliance, and a good reputation thanks to the confidentiality, integrity, and availability of information.
