Irrespective of whether you are an enterprise or an individual, safeguarding information with the utmost security and diligence is of paramount importance. That’s why the ISO/IEC 27001 standard was introduced to help ensure the protection of information.
The international standard ISO 27001 specifies the requirements for an information security management system (ISMS).
An ISMS is a set of policies and procedures designed to safeguard sensitive data from unauthorized access, use, disclosure, or destruction. By implementing an ISMS ISO 27001, organizations can demonstrate their dedication to information security and possibly obtain ISO 27001 certification.
This article aims to provide a comprehensive understanding of the importance and implementation of ISO/IEC 27001 Information Security Management.
What is ISO 27001 certification?
ISO/IEC 27001 is the international information security standard that specifies the requirements for an efficient ISMS (information security management system). ISO 27001 is an international standard that defines the ISMS, or Information Security Management System, within the context of an organization.
ISO/IEC 27001:2013 is the official name for ISO 27001, the international standard for ISMS certification that was developed by a committee comprised of experts from the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
ISO 27001:2013 should not be confused with ISO/IEC 27000:2018, an additional ISO/IEC 27000 standard that aims to define the common terminologies used in the ISMS family of standards.
The Three Building Blocks of ISO 27001
The ISO 27001 standard seeks to secure people, processes, and technology through the C-I-A triad (confidentiality, integrity, and availability).
1. Confidentiality
Confidentiality requires that data and systems be protected from unauthorized access by unauthorized individuals, processes, or applications. Utilizing technological controls such as multi factor authentication, security tokens, and data encryption is required.
2. Integrity
Integrity is the process of confirming the veracity, reliability, and completeness of data. Utilizing processes that ensure data is free of errors and manipulation, such as verifying that only authorized personnel have access to sensitive data, is included.
3. Availability
Typically, availability refers to the upkeep and monitoring of information security management systems (ISMS).
This includes eliminating any security process constraints, minimizing vulnerabilities by updating software and hardware to the latest firmware, enhancing business continuity by adding redundancy, and minimizing data loss by adding backups and disaster recovery solutions.
Importance and Advantages
ISO 27001 is significant because it establishes a benchmark for the type of ISMS framework that businesses and organizations can implement and tailor to their specific requirements.
It establishes a minimum standard for information security management systems that can be expected from any organization, irrespective of size, industry, or location, that wishes to be recognized as having a robust ISMS.
ISO 27001 is one of the most widely adopted information security standards. Independently accredited certification to the standard is internationally recognized. In the past decade, the number of certifications has increased by more than 450%.
Implementing the standard facilitates compliance with regulations such as the UK and EU GDPR (General Data Protection Regulation) and the NIS (Network and Information Systems) Regulations. It also aids in minimizing the costs associated with data breaches.
Some advantages of obtaining ISO 27001 certification include:
- Protecting your data regardless of location: This involves protecting all forms of data, whether they are digital, physical, or stored in the cloud.
- Increasing your resistance to attack: This involves enhancing your company’s resistance to cyberattacks.
- Reducing costs for information security: This involves implementing only the necessary security controls, which will allow you to maximize your budget.
- Addressing evolving security threats: This involves continually adapting to both external and internal changes within the organization.
- Improving company culture: This involves an ISMS encompassing people, processes, and technology, ensuring that employees comprehend risks and incorporate security into their daily work practices.
- Complying with contractual terms: Certification demonstrates your company’s dedication to data security and provides a valuable credential when submitting bids for new business.
Who issues ISO certification in Singapore and Malaysia?
In Singapore, the Singapore Accreditation Council (SAC), which is part of the Enterprise Singapore agency, issues ISO certifications. The SAC is responsible for accrediting certification bodies that issue Singaporean businesses ISO certificates.
In Malaysia, the Department of Standards Malaysia (Jabatan Standard Malaysia or JSM), which falls under the Ministry of International Trade and Industry, issues ISO certifications. JSM is accountable for coordinating and promoting standardization activities in Malaysia, as well as accreditation certification bodies to issue ISO certificates.
How to Achieve ISO 27001 Accreditation
Every organization faces unique obstacles, so its ISMS must be tailored to its specific situation.
These seven stages can assist organizations in obtaining and retaining accreditation:
1. Obtain commitments from key stakeholders
ISO 27001 certification requires adherence to stringent rules and procedures. This implies that the business must implement a number of modifications in order to comply with the standard.
Changes typically begin at the top, so it is essential to identify the appropriate stakeholders and gain their support. In order to secure the cooperation of the employees, it is essential to set clear expectations and keep everyone informed.
2. Identify, classify, and prioritize risks
Conduct a thorough risk assessment of your ISMS and align its security controls with those outlined in ISO 27001. The objective of risk analysis should be to identify which system-specific risks exist and their associated areas of vulnerability.
Prioritize these risks according to the level of danger they pose to the business.
3. Develop a framework for identified risks
Once risks have been identified, it is essential to choose security measures that help mitigate them. In the security policy, all risks, controls, and mitigation methods must be explicitly defined and regularly updated.
This enables organizations to provide clear guidance to their constituents and establish a strategic framework that serves as the basis for information security within the organization.
4. Set clear and precise information security objectives
After identifying the application areas and selecting the controls, the next step is to establish clear benchmarks and expectations. Indicators of performance and efficacy help businesses maintain their focus on attaining their final objectives.
5. Implement security measures
Once the risks, controls, and objectives have been outlined, the business should immediately begin implementing new processes and systems, which may also necessitate a change in workplace culture.
It is possible for employees to resist change; therefore, it is essential to invest adequately in security awareness training programs that sensitize employees and encourage them to adopt security habits and behaviors.
6. Continuously monitor and adjust as required
As a business evolves, so do its processes and systems, and so do its risks. Businesses must continually monitor and modify their security controls to account for the emergence of new threats.
Prior to the actual certification audit, it is advisable to conduct a preliminary audit to uncover concealed vulnerabilities that could negatively impact certification.
7. Concentrate on continually enhancing the ISMS
Security is a process, not a destination. Even if your ISMS has already been audited and certified, it is essential to continue monitoring, adjusting, and enhancing it.
ISO 27001 requires periodic third-party audits (called monitoring audits) to assure continued compliance with the standard. Renewal of certification will only take place if monitoring audits pass.
ISO 27001 vs. ISO 27002
ISO 27001 is a certification standard for information security management systems (ISMS) that outlines the requirements for administering and protecting sensitive data. ISO 27002, on the other hand, is a code of practice that provides implementation and maintenance guidelines for an ISMS.
While ISO 27001 is used for certification, ISO 27002 is a set of guidelines for enhancing information security and is not a certification standard. Both standards are interrelated and are frequently implemented in tandem to create an all-encompassing information security management system.
Final takeaways
Implementing an information security management system (ISMS) compliant with ISO 27001 can provide organizations with a framework for protecting sensitive data.
Obtaining ISO 27001 certification can demonstrate to customers and stakeholders that a company takes information security seriously and has taken steps to safeguard their data.
Nonetheless, implementing an ISMS ISO 27001 is not a one-time process; ongoing maintenance and development are required. Organizations should routinely evaluate their information security policies and procedures to ensure that they are effective and up-to-date.
By following the recommendations in this article, companies can move closer to establishing a safe and efficient information security management system.
