Worldwide standards for information security have been defined by ISO/IEC 27001, a set of global standards. A security program (ISMS) is a system that helps organisations implement, maintain, and continue improving an ISMS (ISMS).
Compliance with the ISO 27001 standard is not required. If you’re concerned about your company’s security, ISO standards can help you decrease risk, meet legal and regulatory requirements, lower expenses, and gain a competitive edge. Your consumers will be more likely to stick around if your company has ISO 27001 certification.
What is the purpose of ISO 27001, and why is it important?
ISO/IEC 27001 is a component of information technology created to assist organisations of all sizes and in various industries in implementing an effective system for managing information security. Risk-based and technology agnostic, the standard is a top-down approach.
ISO 27001 is centred on the concept of risk management. Data that must be protected must be identified, the different ways it is at risk must be determined, and controls must be implemented to limit each risk. Data confidentiality, integrity, and availability are all at risk. Rules and procedures can be selected using the standard as a guide.
Doing so is mandated by the ISO 27001 standard.
- It’s essential to know your stakeholders and what they anticipate from your ISMS.
- Defining a security strategy
- Identify current and future data security issues by performing a risk assessment.
- Manage the risks by establishing procedures and controls.
- Set specific goals for each step in the information security process.
- Rules and other risk-reduction measures should be implemented.
- Take a hard look at your ISMS Requirements and Control Mechanisms and make adjustments.
Requirements of the ISO 27001 standard
Mainly, it is a standard with two sections. The following number of clauses comprise the first section’s definitions and requirements:
- It provides an overview of how to manage information risks in an organised manner.
- ISMS criteria that apply to businesses of all sizes and types are included in the scope.
- Only one other standard, ISO/IEC 27000, is specified as a normative reference. However, it contains essential information for establishing ISO 27001 certification.
- It explains some of the more difficult words used in the standard.
- Provides information on why and how to identify the various internal and external factors that may impact an organisation’s capacity to deploy an ISMS while mandating that an ISMS be developed and consistently improved within the business.
- Requires management to exhibit support and direction to the information security management system, mandate policy and allocate information security roles
- Explains how to detect, assess, and prepare to deal with information risks and outlines the goal of information security efforts.
- This requires organisations to provide enough resources, increase awareness, and gather required documents.
- Details on how to analyse and treat risk exposures, manage changes and guarantee correct documentation are included in this section.
- Monitoring, measuring, and analysing an organisation’s information security risk management controls or processes is required for performance evaluation.
- Continual improvement of an organisation’s ISMS is required, as is responding to audit and review results.
Related Controls and Controls as a Reference
If you’re having trouble meeting the first section’s requirements, Annex A provides additional guidance. Your company should choose the controls that best suit its particular needs, plus feel free to add more rules if necessary.
The following are the domains into which the controls are divided:
Defining the roles and duties of each member of the information security team
- Security of human resources: To ensure that employees and contractors are aware of their responsibilities.
- Asset Management: Asset Management is necessary to ensure that businesses identify their data assets and specify the proper protective obligations.
- Allowing employees to access only the information relevant to their duties is the goal of access controls.
- Encrypting data to keep it private and secure is the purpose of cryptography.
- Controlling equipment to avoid loss, damage, and theft of software, equipment, and physical files and preventing illegal physical access to premises or data.
- To keep data processing facilities safe, operations security is needed.
- Information network security requires strong communication security.
- The process of acquiring, developing, and maintaining systems to safeguard both internal and external networks that deliver services
- Relationships with Suppliers — To correctly manage contracts with third parties.
- Security Incident Management (SIM) ensures that occurrences are collected and reported effectively.
- Management of Information Security in Business Continuity — to minimise downtime
- Ensuring and reducing the likelihood of noncompliance with applicable laws and regulations is the goal of compliance.
- Compliance with and Certification to ISO 27001
Your organisation can lower cybersecurity risks and better meet data protection regulations by voluntarily adopting ISO 27001 requirements. You may show your clients, partners, suppliers, and others that you are serious about safeguarding your data assets by obtaining ISO 27001 accreditation. Your company’s reputation and competitive advantage can be bolstered by establishing this level of trust.
