ISO 27001:2022 – Information Security Management System

Introduction To ISO 27001 Certification (ISMS)

What is ISO 27001

ISO 27001 is an information security standard that is aligned with the requirements of today’s information technology sector and making the secure environment of the information shared by the customer or the information shared internally. Being certified against the standard ISO 27001 ensures that your organization has successfully implemented an Information Security Management System (ISMS) and has been assessed by the competent Certification body.

ISO 27001 provides a framework and guidelines to implement ISMS that gives organizations a fundamental structure to manage their information security and has all the relevant and required policies and procedures in place to secure the data in their premises.

History of ISO 27001

The British Standards Institute Group (BSI Group) sought to define IT standards outlining how organizations should design their ISMS to secure their information assets as cybersecurity needs to be evolved and more organizations adopted ISMS.

In 1995, the BSI collaborated with the Department of Trade and Industry (DTI) of the United Kingdom Government to develop vendor-neutral standards that ensure the availability, confidentiality, and integrity of an organization’s data and proprietary information. These critical IT standards, known as BS 7799, formed the basis for today’s ISO 27001 standard.

The first section of BS 7799 addressed general information security management standards. After several revisions, the ISO adopted the first part of BS 7799 and renamed it ISO/IEC 17799 in 2000.
In 2007, it was renamed ISO/IEC 27002 after further revisions. ISO 27002 provides additional guidance for implementing ISO 27001-recommended security controls.

The second and third parts of BS 7799 were eventually adopted as ISO 27001:2005 standards. These guidelines define standards for risk analysis within ISMS processes, procedures, and controls, as well as how to implement an ISMS. In 2005, the ISO adopted both parts, including a certification option for organisations to demonstrate ISO 27001 compliance.

The Annex SL template was introduced in the most recent version of ISO 27001 cybersecurity by definition, which was updated in 2013. This high-level structure ensures that all systems have a consistent appearance, feel, compatibility, and functionality in order to meet multiple ISO standards. Although this certification got recently updated in the year 2022, this high-level structure ensures that all systems have a consistent appearance, feel, compatibility, and functionality in order to meet multiple ISO standards.

Why ISO 27001 is Important?

Companies have become more vigilant about their cybersecurity methods as data breaches have become more common. Many organizations now expect their partners and vendors to manage their data with the same vigilance.

Data, organizational information, and other infor mation assets must be kept secure, and many clients and partners expressly state security expectations in their contracts. ISO 27001 certification, as the only globally recognized standard for information security management, has become a competitive advantage that demonstrates an organization effectively manages its information assets.

When compared to similar regional standards defined by individual countries, ISO 27001 is frequently regarded as a more stringent security standard. This is due, in part, to ISO 27001’s emphasis on all three pillars of information security: people, processes, and technology.

Unlike IT security initiatives that only concern the IT department, ISO 27001 information security standards concern the protection of information assets throughout the organization. This means that multiple teams have been trained and are committed to protecting company information and data in order to maintain high compliance standards.

ISO 27001 Structure (ISMS)

ISO 27001 got updated in 2013 and the updated version of the ISO 27001 framework adopted a two-part structure.

Part 1 Of ISO 27001 ⮯

The first section of ISO 27001 describes 11 clauses (numbered 0-10) that cover the general standards as well as the mandatory requirements and documents that an organization has in order to be compliant with ISO 27001. The first four clauses provide context to help your organization understand what ISO 27001 is for and how to prepare for an ISO 27001 audit, elaborating on the details.

ISO 27001 provides a framework and guidelines to implement ISMS that gives organizations a fundamental structure to manage their information security and has all the relevant and required policies and procedures in place to secure the data in their premises.

2. The Scope of ISO 27001

3. Normative References

4. Relevant Terms and Definitions

This section explains how to make the ISMS Scope document. This document defines the scope of your organization’s ISMS, as well as the elements of your ISMS.
ISMS are audited for certification and to determine which controls are applicable to the scope of your project.

This section assists organisations in developing a Policy Statement, which explains the stakeholders involved in ISMS implementation and demonstrates
The leadership team’s commitment to achieving ISO 27001 compliance is outlined, as is who will complete ISMS maintenance tasks.

This section assists organisations in developing goals based on risks and opportunities. This information is used by organisations to develop a plan for maintaining a risk-based approach to ISMS management and determining how they will monitor and measure their objectives.

This section guides organisations through the process of determining how they will manage resources to maintain and improve their ISMS in accordance with five essential activities: competence, awareness, communication, documentation, and records management.

This section guides organizations through the process of defining procedures for measuring, monitoring, and maintaining ISMS records. It also contains information on creating an internal audit schedule and conducting management reviews to address corrective actions for issues discovered during audits.

This section assists organizations in risk mitigation by generating the required risk assessment report and risk treatment plan.

Aids organizations in developing a process for recording and managing improvement recommendations and non-conformities discovered during audits.

The initial ISO 27001 certificate eligibility certification process consists of two stages: a documentation review audit and an evidential audit. Part 1 of the ISO 27001 structure’s clauses assists organizations in preparing written documentation, processes, procedures, and guidelines that explain your ISMS implementation and the business processes that support it.

During the Stage 1 Documentation Review, these documents are reviewed by an approved, objective auditor. The auditor ensures that a company’s documentation complies with ISO 27001 standards during this first stage and may recommend certification.

Part 2 of ISO 27001 ⮯

An approved auditor from an accredited certifying body reviews your organization’s ISMS processes and controls in action during Stage 2 of the initial certification process. Finding evidence that controls in place work effectively, efficiently, and in accordance with the documented processes reviewed in Stage 1 is part of this audit.

The second section of ISO 27001 is known as Annex A. Depending on the scope of their ISMS certification, this section details 114 controls across 14 domains that organizations should implement or follow.

Not all controls will be applicable to every company’s implementation. Instead, in a Statement of Applicability, the company defines which controls are relevant based on their scope (SoA).
In the SoA, the organization justifies whether or not to implement any of the 114 ISO 27001 controls based on the assessment, business need, or legal/contractual obligation.

After defining the relevant controls, an auditor gathers evidence to demonstrate that the controls identified in the SoA align with the standards outlined in Annex A. If these controls and appropriate business processes are implemented correctly, an organization is eligible for ISO 27001 certification.

Quality / Principles of ISO 27001

ISO 27001 along with an Information Security Management System serves the goal to protect three aspects of an information:

  • Information security risk treatment plan
  • Compliance to Statement of Applicability and related policies, procedures and the record evidences.
  • Definition of security roles and responsibilities
  • Operational planning and control
  • Results of the information security risk assessment
  • Results of the information security risk treatment
  • Evidence of the monitoring and measurement of results
  • A documented internal audit process
  • Evidence of the audit programs and the audit results
  • Evidence of the results of management reviews
  • Evidence of the results of any corrective actions

Organizations may also include non-mandatory records to provide additional evidence of security- processes, decisions, and actions. Documentation is required for certification, so keep meticulous records with clear justifications for your decisions. The better your documentation, the more efficient the audit process and hence the opportunity to grow and improve yourself will be better.

Process Of Getting ISO 27001 Certified

The ISO Certification Process has mainly three different phases

This is the stage at which you identify and implement the security policies and controls that will comprise your ISMS.
An external auditor will review and assess your ISMS for compliance once it is in place. The audit is divided into two stages: a preliminary assessment of your ISMS documentation and a formal review for certification.
Finally, the ISO 27001 framework emphasizes ongoing maintenance and continuous improvement. During this phase, you will monitor and assess the posture of your security system on a regular basis, and you will adjust your policies as needed to ensure compliance and best practices are followed.

Benefits of ISO 27001

Meeting the stringent ISO 27001 standards for certification can be time-consuming and resource-intensive, often taking up to 18 months from the start of the initial in addition to the baseline. Regardless of these requirements, ISO 27001 certification provides numerous benefits that will set your organization apart from the competition.

ISO 27001 certification is not limited to a single industry. In fact, organizations from all industries benefit from maintaining this high level of security. IT, finance, telecom, healthcare, and government are some of the primary industries that have ISO 27001 certification.

FUTURE OF ISO 27001 Certification (ISMS)

A new version of ISO 27001 has been published recently that has increased trust on digital platforms and addressing the increased rate of Cybercrimes.
