A Practical Guide to Essential IT Security Standards for Modern Organizations

The rapid advancement of digital technology brings new opportunities and significant risks. As organizations navigate complex landscapes—from onboarding cloud solutions to integrating AI, IoT, or big data—ensuring robust information security, privacy, and scalable systems is non-negotiable. That’s why international IT security standards are a must: they help manage identity, authenticate users, ensure cryptographic integrity, and maintain trustworthy, confidential operations. In this article, we break down four of the most essential IT security standards, highlighting why these frameworks are crucial for productivity, compliance, and organizational growth.

Overview

Information security underpins our digital lives, enabling trust in online transactions, sensitive data exchange, and remote work. Standards provide a shared language and criteria for organizations to assess, enhance, and scale their security and privacy programs, a critical capability as new technologies are continuously adopted. Here you will find a comprehensive overview of:

• Identity management frameworks and reference architecture
• Secure and privacy-protecting biometric authentication—especially for mobile, remote contexts
• Confidential, collaborative data processing using secure multiparty computation
• Robust field testing for cryptographic modules, foundational for encryption-based trust

By understanding and applying these international standards, businesses and institutions can:

• Reduce risk of cyberattacks, breaches, and financial loss
• Meet global regulatory and contractual requirements
• Foster productivity and innovation through secure technology adoption
• Enable secure scaling and interoperability across platforms and markets

Detailed Standards Coverage

ISO/IEC 24760-2:2025 – Reference Architecture for Identity Management

Information security, cybersecurity and privacy protection — A framework for identity management — Part 2: Reference architecture and requirements

This standard delivers a comprehensive framework for implementing and operating identity management systems. It defines architectures, processes, and stakeholder roles, distinguishing the vital concepts of “identity” (who/what something is) versus “identifier” (the unique string or value representing an identity). ISO/IEC 24760-2:2025 provides clarity for managing identities of people, devices, and software—critical as digital transformation continues to accelerate.

It offers an in-depth reference architecture addressing internal and external deployments, key actors (like identity information providers, verifiers, auditors), and the end-to-end lifecycle management of identity information. Functional requirements ensure that policies govern information quality, secure storage, access, and eventual termination or deletion. Privacy-by-design sits at the core—helping organizations comply with laws such as GDPR while securing stakeholder trust.

Who needs to comply:

• Any organization storing or processing identity information—businesses, government, healthcare, education, cloud platforms, and IT vendors.

Practical implications:

• Provides a blueprint for integrating identity management seamlessly within business processes
• Streamlines interoperability across platforms and simplifies vendor due diligence
• Enables scaling user bases securely (e.g., employees, customers, IoT devices)

Notable features:

• Horizontal standard: foundational for all sectors handling identity
• Governance and compliance built-in (audit-ready)
• Enhanced privacy controls and stakeholder transparency

Key highlights:

• Defines best practices and architecture for managing identities and identifiers
• Establishes lifecycle management: creation, update, and deletion protocols
• Ensures privacy, accuracy, and compliance with global obligations

ISO/IEC 27553-2:2025 – Secure Biometric Authentication on Mobile Devices (Remote Modes)

Information security, cybersecurity and privacy protection — Security and privacy requirements for authentication using biometrics on mobile devices — Part 2: Remote modes

Biometric authentication (using fingerprints, face, voice, etc.) has become mainstream in mobile device security. This standard sets high-level requirements for implementing secure, privacy-friendly biometric authentication when biometric data is transmitted off the device to remote services—covering remote authentication scenarios essential to banking, e-government, and digital identity ecosystems.

ISO/IEC 27553-2:2025 tackles advanced security and privacy issues unique to remote modes, including secure communication channels, storage, and processing, plus threat analysis (e.g., eavesdropping, presentation attack detection). The standard is particularly valuable for institutions deploying mobile authentication solutions that connect to cloud services or third-party platforms.

Who needs to comply:

• Mobile device manufacturers, app developers, cloud service providers, and organizations enabling remote biometric authentication.

Practical implications:

• Standardizes controls to safeguard users against identity theft, AI-generated forgeries, and data leaks
• Builds user (and market) trust by addressing privacy and regulatory requirements
• Balances ease-of-use with strong, remote-friendly authentication

Notable features:

• Technology-agnostic: covers a variety of mobile platforms
• Addresses secure data transmission and remote storage
• Includes threat modelling, privacy controls, and workflow recommendations

Key highlights:

• High-level requirements for transmitting biometric data safely
• Focus on authentication workflows between mobile and remote services
• Detailed threat models addressing emerging vulnerabilities

ISO/IEC 4922-2:2024 – Secure Multiparty Computation Using Secret Sharing

Information security — Secure multiparty computation — Part 2: Mechanisms based on secret sharing

Modern organizations increasingly require collaborative analytics, federated machine learning, and secure multi-party workflows that protect data confidentiality (for example, enabling several hospitals to analyze aggregate health data without revealing individual patient records). ISO/IEC 4922-2:2024 specifies protocols and mechanisms for secure multiparty computation (SMPC) based on secret sharing—a cryptographic technique that divides sensitive information among multiple parties, ensuring that only authorized collaborations can recover the underlying data.

The standard elaborates on operations such as secure addition, subtraction, multiplication, and random number generation, providing algorithms, requirements, and mathematical properties. Applications include privacy-preserving analytics, secure voting, collaborative fraud detection, and joint research across competitive or regulated environments.

Who needs to comply:

• Organizations conducting confidential joint computations—finance, healthcare, research, defense, technology alliances

Practical implications:

• Enables GDPR-compliant cross-border analytics and artificial intelligence
• Reduces risk of insider leak or external breach during collaboration
• Promotes transparency and auditability in multiparty operations

Notable features:

• Supports a range of cryptographic secret sharing schemes
• Modular and extensible for custom secure computation needs
• Detailed example use cases and security considerations

Key highlights:

• Protects data in collaborative environments without exposing secrets
• Specifies protocols for a full suite of mathematical operations
• Facilitates secure, privacy-preserving business intelligence
