What are cyber security standards?

Cyber security standards are guidelines and best practices established to protect data and information systems from cyber threats and ensure compliance with regulations and industry standards.

These guidelines include a set of controls and methodologies that your organisation can implement to strengthen its defences against potential cyber security attacks. By adhering to these standards, you can establish a robust information security management system (ISMS) to identify, assess, and manage risks effectively.

Cybersecurity standards promote adopting proactive measures to maintain the integrity and confidentiality of information assets.


Why are cyber security standards important?

By implementing cyber security standards, you can mitigate cyber risks, protect against threats, and establish a secure environment through certified processes and infrastructure.

These standards ensure that your organisation has defence mechanisms to safeguard its digital assets against cyber attacks, data breaches, and other security vulnerabilities.

Cyber security standards help organisations in their risk management efforts by providing guidance for establishing a comprehensive cyber security posture. Through certifications and audits, your business can demonstrate its commitment to maintaining high levels of security and compliance with industry regulations.

What are the different types of cyber security standards?

There are various aspects of information security, controls, and cyber risk management when safeguarding your organisation. That's why cyber security standards include technical, organisational, and legal components to address these different security aspects.

Technical standards

In cyber security, technical standards define specific controls, best practices, and measures to address vulnerabilities in IT infrastructure and safeguard critical assets.

These standards help establish a secure framework for your organisation to operate within the digital landscape. By implementing these guidelines, you can effectively manage risks associated with cyber threats and ensure the confidentiality, integrity, and availability of your company's data and services.

Vulnerability assessments help identify weaknesses in the system that malicious actors could exploit. This proactive approach allows your business to address vulnerabilities promptly and strengthen its overall infrastructure protection against potential breaches.

Organisational standards

The focus of organisational standards is on establishing processes, procedures, and auditing mechanisms to ensure compliance with cyber security standards and industry best practices.

These guidelines shape your organisation's operational framework, navigating the development of strategies to safeguard sensitive data. Implementing a structured approach enhances resilience against cyber threats and data breaches.

Audit protocols within these standards systematically evaluate adherence to guidelines, driving continuous improvement.

Legal standards

Legal standards in cyber security include regulatory requirements set by governments and industry bodies such as GDPR and HIPAA to ensure compliance and data protection.

The General Data Protection Regulation (GDPR) dictates how personal data should be handled, stored, and protected, ensuring transparency and accountability in data processing. It affects any organisation that processes the personal data of individuals in the European Union (EU) and the European Economic Area (EEA).

Similarly, the Health Insurance Portability and Accountability Act (HIPAA) establishes standards for the protection of sensitive patient health information, aiming to safeguard the confidentiality and integrity of healthcare data in the United States. While HIPAA is a US regulation, private providers from the UK operating in the US must also adhere to it. 


How are cyber security standards developed?

Cyber security standards are developed by governmental agencies, industry associations, and international organisations to address evolving cyber threats. But in which way do they contribute to these standards?  

Governmental agencies

Government agencies develop cyber security standards to combat cyber attacks, enforce regulations, and enhance national cyber security frameworks.

These agencies set the guidelines and requirements that organisations must adhere to in order to protect critical infrastructure and sensitive data. In response to cyber attacks, these entities often lead investigations, collaborate with other agencies, and provide support to affected organisations.

Industry associations

Industry bodies contribute by sharing best practices and tailored solutions based on their expertise, fostering collaboration within specific sectors.

These associations guide organisations towards a more secure digital landscape. By facilitating coordination among industry players, they ensure that cyber security standards are robust and up-to-date.

International organisations

International organisations such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) provide a platform for harmonising cyber security standards on a global scale. They drive the development of global standards like ISO 27001 and the NIST cybersecurity framework to improve cyber security practices.

These global standards provide a common ground for organisations to improve their security posture and facilitate international collaboration and information sharing.


What are the most commonly used cyber security standards?

There are many different cyber security standards. Let's find out which ones you should know about. 

ISO 27001

ISO 27001 is a leading standard for information security management systems (ISMS), providing guidelines for certification, audits, and implementation of effective security controls. Organisations that adhere to ISO 27001 demonstrate a commitment to protecting sensitive information assets and ensuring the confidentiality, integrity, and availability of data.

The certification process involves a thorough assessment by accredited auditors, evaluating the organisation's compliance with the requirements set forth in the standard. Regular audits are critical to maintaining certification and continuously improving the ISMS to address emerging risks and vulnerabilities.

Security controls outlined in ISO 27001 cover a range of areas, including access control, cryptography, physical security, and incident management, all aimed at safeguarding information from unauthorised access and breaches.

PCI DSS is a standard for payment card industry compliance, emphasising secure processes, audits, and controls to protect cardholder data and ensure regulatory adherence.

Compliance with PCI DSS isn't just a recommendation but a requirement for organisations handling payment card transactions. By setting stringent guidelines, this standard enhances data security measures and reduces the risk of fraud or data breaches.

The PCI Security Standards Council dictates the requirements that organisations must meet, including regular audits and assessments to validate their adherence to the PCI DSS standards. These audits involve a thorough inspection of policies, procedures, and infrastructure to ensure that proper data protection controls are in place.


The NIST cybersecurity framework offers guidelines on effective controls, risk management, and handling vulnerabilities to enhance the cyber security posture of organisations and critical infrastructure.

Structured around five core functions, the framework provides a systematic approach to addressing cybersecurity risks. It emphasises the importance of identifying, protecting, detecting, responding to, and recovering from cyber threats.

Control categories such as access control, data protection, and security training form the foundation of the framework, guiding organisations in establishing robust security measures.

HIPAA Security Rule

The HIPAA Security Rule sets standards for safeguarding sensitive information in healthcare, emphasizing compliance, data protection, and regular audits for security assurance.

Protecting individuals' health data is not just a regulatory requirement; it also builds trust with patients and maintains the reputation of the healthcare institution.

Compliance with the HIPAA Security Rule involves implementing physical, technical, and administrative safeguards to secure electronic protected health information.
