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 organization 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 organizations 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 organizations 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 organizations.

Industry associations

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

These associations guide organizations 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 organizations

International organizations 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 organizations 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. Organizations 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 organization'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

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 organizations 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 organizations 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.

NIST

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