Everything You Should Know About ISO 27001

What ISO 27001 Is And Who Needs It 

ISO 27001 is an internationally recognized framework that provides guidelines for effectively managing IT security and establishing an information security management system (ISMS) to safeguard consumer data. Achieving ISO 27001 certification involves undergoing a thorough audit conducted by an accredited auditor, verifying an organization's adherence to the specified standards.

This esteemed certification holds particular significance for businesses operating outside the United States, as it serves as evidence of robust security practices and bolsters trust among potential customers and business partners. Compliance with ISO 27001 signifies an organization's commitment to maintaining a secure and reliable environment for handling customer data.

The requirements of ISO 27001 offer flexibility, as not all standards need to be implemented for certification. The framework encompasses a total of 114 controls distributed across 14 categories. Organizations are tasked with assessing their own infrastructure, data, and information security management system and implementing the controls that align with their unique operational context.

Determining the success of ISO 27001 implementation involves identifying key performance indicators (KPIs) tailored to the organization's ISMS. These KPIs serve as metrics for evaluating the effectiveness of the system in ensuring data and system security. Although the specific KPIs will vary based on the organization's ISMS, tracking and monitoring these indicators are integral to maintaining a secure environment and achieving ISO 27001 compliance.

ISO 27001 provides a globally recognized framework for effectively managing IT security, instilling trust in customers and partners, and ensuring the confidentiality and integrity of sensitive information.

2022 Updates and Their Impact on Your Organization

In 2022, significant changes were introduced to ISO 27001 and 27002 (a supporting standard of ISO 27001 that guides how the information security controls can be implemented) standards, warranting a closer look at how they will affect organizations already certified or preparing for certification. This article aims to provide detailed insights into the fundamental changes and their potential implications.

‍

Formal Publication

As of July 2022, the formal publication of the revised ISO 27001 standard is pending. However, a reliable preview is available based on the alignment of Annex A controls with the recently published ISO 27002 in February 2022. 

‍

Implementation Timeline

While the specific timeline for adoption has not been finalized, experts anticipate an adoption period of around 18 to 24 months.

‍

Unchanged Management Clauses

Organizations familiar with ISO 27001 understand that it primarily functions as a management standard. The management requirements outlined in ISO Clauses 4 through 10, which pertain to implementing and maintaining an Information Security Management System (ISMS), are not expected to remain the same.

‍

Changes to Annex A Controls

The major revisions will be observed in the Annex A controls, which organizations utilize to mitigate and manage information security risks. Although not mandatory, the majority of organizations choose to implement the majority of Annex A controls due to their broad applicability in addressing the information security risks commonly faced by organizations.

‍

Organization of the controls

The current framework consists of 114 controls categorized into 14 sections (A.5-A.18). In the 2022 version, the controls have been reorganized into four categories (A.5-A.8), resulting in 93 controls. Although the organization of controls has changed substantially, the content remains largely consistent.

‍

Control Attributes

A noteworthy addition is the introduction of an "Attribute Table" for each control, which includes five metadata attributes: Control type (preventative, detective, corrective), Information security properties (confidentiality, integrity, availability), Cybersecurity concepts (identify, protect, detect, respond, recover), Operational capabilities, and Security domains. These attributes give users a deeper understanding of the purpose and function of each control.

The categories of Attributes are:

• Control type
• Information security properties
• Cybersecurity concepts
• Operational capabilities
• Security domains

The Control types indicate “when and how the control modifies the risk.” The meaning of the three types is fairly self-evident:

• Preventative
• Detective
• Corrective

Preventative control is implemented to prevent information security events or incidents proactively. Detective control helps identify potential occurrences of such events or incidents, while corrective control is utilized to respond to an incident and restore a secure operating environment. The Information security properties pertain to the specific aspects of information security protection that each control contributes to, aligning with the well-known "CIA Triad":

• Confidentiality
• Integrity
• Availability

The Cybersecurity concepts serve as a logical grouping that is associated with the controls in ISO 27110. These concepts share similarities with the logical grouping utilized in the NIST Cybersecurity Framework. The concepts are:

• Identify
• Protect
• Detect
• Respond
• Recover

The Operational capabilities outline 15 practitioner capabilities that are supported by these controls. While the majority of controls are associated with a single capability, a few controls are relevant to multiple capabilities. The capabilities are:

• Governance
• Asset management
• Information protection
• Human resource security
• Physical security
• System and network security
• Application security
• Secure configuration
• Identity and access management
• Threat and vulnerability management
• Continuity
• Supplier relationships security
• Legal and Compliance
• Information security event management
• Information security assurance

Finally, the controls are grouped into four high-level Security domains:

• Governance and ecosystem
• Protection
• Defense
• Resilience
