- Summary
According to IBM’s Cost of Data Breach Report, the global average data breach cost reached $4.88 million in 2024 (a 10% increase compared to 2023), the most significant jump since the pandemic. 70% of breached organizations stated that the incident caused considerable disruption within their operations and affected their users’ loyalty and trust. ISO 27001, or ISO/IEC 27001, is a global standard that allows organizations to handle the security of employee/client details, financial information, intellectual property, and others. It also improves the user confidence in an organization’s capabilities for handling sensitive data and establishing a risk management process.
What is ISO 27001, and Who is it for?
ISO 27001 is an international standard published by the International Organization for Standardization (ISO) for information security, part of the ISO/IEC 2700 series. It describes how organizations should manage all security components. The full name is “ISO/IEC 27001—Information security, cybersecurity, and private protection—Information security management systems—Requirements.”
ISO 27001 framework consists of requirements for defining, integrating, operating, and optimizing an Information Security Management System (ISMS). Its primary function is to secure organizational information (regardless of the size or industry) cost-effectively and systematically. Any enterprise that deals with data can benefit from ISO 27001 compliance.
Why is ISO 27001 Compliance Important?
ISO 27001 compliance assists businesses in the digital age in establishing a robust framework to protect sensitive information, mitigate security risks, and ensure operational continuity. Companies can also get ISO 27001 certified, which can help them prove to their customers and partners that they are highly capable of protecting their data. According to this compliance, the primary goal of an ISMS is to protect three components of information, which are:
- Integrity: Only authorized users can change/update information.
- Availability: Information should be accessible to authorized users whenever and wherever they need it.
- Confidentiality: Only authorized users should have the right to access information.
How Many Controls does ISO 27001 have?
The latest version of ISO/IEC 27001: 2022 includes 93 controls organized into four themes across Annex A. These controls are well streamlined and consolidated compared to the previous ISO 27001:2013 version, which had 114 controls across 14 categories. The updated version more profoundly addresses modern security challenges like cloud security and threat intelligence. Let’s take a look at the four categories:
| Category Name | Number of Controls | Description |
| A.5 Organizational Controls | 37 | It contains controls for setting the most critical security documentation and processes. |
| A.6 People Controls | 8 | It focuses on controls associated with secure management of human resources. |
| A.7 Physical Controls | 14 | It contains controls related to equipment security and secure areas. |
| A.8 Technological Controls | 34 | It focuses on communication and IT controls. |
ISO 27001 is currently used by organizations worldwide to keep their Information Security Management Systems (ISMS) up to date and ensure they comply with current best practices. It is divided into 14 phases:
- Define ISMS Scope
- Design and Organize Information Security Policy
- Perform Risk Assessment and Treatment
- Define, Review, and Implement Access Control
- Define or Review Cryptography and Technical Controls
- Develop Physical, Operational, and Communication Security Procedures
- Allocate Resources and Provide Training
- Implement ISMS
- Monitor and Measure ISMS Performance
- Conduct Internal Audits
- Management Review of the ISMS
- Address Nonconformities and Corrective Actions
- Certification Audit
- Continuous Improvement (PDCA Cycle)
Why do Businesses Require an Information Security Management System (ISMS)?
An information security management system enables businesses to define a particular ruleset and identify stakeholders, objectives, and risks within a security posture. Companies can keep these rulesets as policies, strategies, and other technologies and processes as they don’t require any documentation. The primary benefits that an organization can achieve with ISO 27001 implementation are:
Lower Costs:
ISO 27001’s primary function is to prevent security issues from arising and disrupting the organizational flow. No matter how big or small a security incident is, it will always cost money (sometimes a lot). Therefore, by leveraging ISO 27001 for ISMS implementation, businesses can prevent security incidents and save money. The best part is that investing in this compliance is far cheaper than the cost benefits businesses will achieve.
Compliance with Legal Standards:
The laws, regulatory requirements, and standards will never be enough when dealing with information security. There will constantly be endless rules, but the good news is that ISO 27001 can cater to most of them. For example, what ISO security standard would be the best fit if you want to create your organization’s security policy in compliance with the EU GDPR or NIS 2? The answer is ISO 27001.
Better Management:
Sometimes, businesses skip defining their processes and producers, which causes their employees not to know what needs to be done, by whom, and when. Implementing ISO 27001 in ISMS setup assists in resolving this issue by encouraging businesses to define their processes, including non-security-related ones. This reduces employee downtime and helps preserve crucial knowledge even when team members leave.
Competitive Benefit:
When a business gets ISO 27001 certified, but the competitor doesn’t, they would have the edge over them as users would prefer the one who can keep their information safe.
