What Is ISO 27001?

Many organisations are able to control the security of a variety of assets thanks to information security management systems. An information security management system can be established, run, maintained, and improved over time using the framework provided by ISO 27001. The standard aids in streamlining procedures to increase organisational security. Ten management system clauses, including scope, normative references, terminology and definitions, context, leadership, planning and risk management, support, operations, performance evaluation, and improvement, are contained in the standard. The standard also contains more than 100 information security rules. Not all of the controls must be used, but a risk analysis can help identify which are most suitable.

ISO 27001’s goal and the ISO framework

The ISO framework is a collection of rules and procedures that businesses can use. By implementing an Information Security Management System, ISO 27001 offers a framework to assist enterprises of any size or industry in protecting their information methodically and affordably (ISMS).

What makes ISO 27001 crucial?

Not only does the standard give businesses the knowledge they need to protect their most precious data, but a business can also become certified against ISO 27001 and, in this way, demonstrate to its clients and business partners that it is committed to securing its data.

Additionally, individuals can demonstrate their qualifications to future employers by becoming ISO 27001-certified through the completion of a course and exam.

Since ISO 27001 is an international standard, it is widely accepted, which expands the commercial potential for businesses and individuals.

What are the three security goals?

Protecting three types of information is the fundamental objective of ISO 27001:

  • Only those who have been given permission may access information, which is Confidential.
  • Integrity: The information can only be modified by authorised individuals.
  • Accessibility: The data must be available to authorised individuals at all times.

ISO 27001’s Benefits for Your Organisation

For your organisation, implementing ISO 27001 when developing or enhancing an information security management system offers several advantages. It guarantees that your company’s data is secure and that it is more resistant to cybersecurity attacks. Utilizing this standard will assist in implementing only the security measures necessary for your organisation, lowering information security expenses. Employing the ISO 27001 standard also enables organisations to react to changes both inside and outside of the organisation and to be prepared to handle security threats as they change. Organisations can use ISO 27001 to comply with all information security and data privacy regulations.

How is ISO 27001 implemented?

The goal of ISO 27001 is to safeguard the availability, confidentiality, and integrity of information within a firm. This is accomplished by determining the potential issues that could arise with the information (i.e., risk assessment) and determining what needs to be done to address those issues before they arise (i.e., risk mitigation or risk treatment).

Therefore, the basic tenet of ISO 27001 is based on a method for managing risks: identify the hazards and then methodically address them by putting security controls in place (or safeguards).

How are ISO 27001 controls implemented?

Information systems use software, hardware, and firmware components added to the system to implement technical controls. Among others, backups, antiviral software

Establishing guidelines and expectations for people, hardware, software, and systems helps organisations put controls in place. For instance, the BYOD Policy and Access Control Policy.

Legal controls are put into place by making sure that procedures and expected conduct adhere to and uphold the laws, rules, contracts, and other similar legal documents that the company is required to abide by. For instance, a service level agreement (SLA), a non-disclosure agreement (NDA), etc.

To apply physical controls, equipment or technologies that physically interact with people and objects are typically used. For instance, locks, alarm systems, and CCTV cameras.

Human resource controls are put into place by giving people the knowledge, education, skills, or experience they need to carry out their tasks safely. For instance, training for internal auditors in ISO 27001 compliance.

“ISO 27001 certified” refers to what?

A firm or business can become certified to ISO 27001 by asking a recognised certification authority to carry out the certification audit and, if the audit is successful, to grant the organisation the ISO 27001 certificate. The organisation will be entirely in compliance with the ISO 27001 standard thanks to this certificate.

A person who completes ISO 27001 training and passes the exam can pursue ISO 27001 certification. This certificate will serve as proof that the recipient completed the course and learned the necessary skills.
