Zero Trust in IAM: The New Approach to Security

The digital security landscape has undergone significant evolution over the last few years. With the increasing number of employees working remotely, the traditional “boundaries” for data and communications have all but washed away. 

Combined with strong Identity and Access Management, a Zero-trust Model for enterprise security can work to secure digital assets and communications. The purpose of Zero-trust identity and access management is to enable a holistic security approach by recognising that threats can originate from both external and internal sources. 

By enforcing strict access controls and identity management, Zero-trust IAM prevents unauthorised access to the network. In this blog, let us learn in detail about Zero-trust in identity and access management.

What are IAM and Zero-trust?

Zero-trust is a security framework that works on the principle of “never trust, always verify”. This security model relies on the assumption that no part of the networking system or computer can be implicitly trusted, including the users operating it.

The purpose of the Zero-trust security model is to implement strong authentication and access controls. Identity and access management (IAM) refers to the process, policies and technologies that enable businesses to control and manage user identities, privileges and access to applications and systems.

The purpose of the IAM solution is to ensure that only authorised users can access sensitive data and applications. Combining these two offers a modern security framework for businesses. It helps in minimising the segment access and blast radius. The Zero-trust IAM verifies end-to-end encryption and uses analytics to enhance defence mechanisms, improve visibility and more.

Why is Zero Trust IAM Crucial for Businesses?

Unlike the traditional security model, which operates on the principle of “trust and verify,” Zero-trust Identity and Access Management works on the concept of implicit zero trust, which helps prevent security breaches and data loss. Here are some reasons why Zero-trust identity and access management is crucial for business:

Mitigate Insider Threats

Insider threats are the most challenging security concerns for businesses. Whether malicious or accidental, it poses a significant risk to a business's reputation. The traditional security model often fails to detect insider threats from users who already have access to the network, system, or resources. 

However, with Zero-trust IAM, no implicit trust is provided, even to internal users. Furthermore, it also offers granular access control, allowing users to access only the resources they need.

Defend Against External Cyberattacks

External attacks, such as ransomware and phishing, are among the sophisticated techniques that cause harm to businesses. These attacks can easily compromise credentials and circumvent traditional security measures. 

However, with IAM and zero-trust security, businesses can employ multi-factor authentication, where users must go through multiple verification processes before gaining access. Furthermore, with micro-segmentation, businesses can prevent lateral movement within the network.

Secure Remote Work

Traditional perimeter-based security is of no use in a remote work culture. In this, users can access corporate resources from various devices and locations, which enhances the risk of unauthorised access. However, zero-trust in IAM helps ensure that only trusted users and devices can access sensitive data. 

Furthermore, it also provides secure and policy-based access to the corporate system, regardless of location. It also helps in assessing the device's health to prevent any breaches and attacks due to system or device vulnerabilities.

Future Proofing Security

With the rapid shift to cloud computing, hybrid work and mobile-first environments, security strategies must evolve to meet new and unpredictable challenges. Traditional perimeter defences are no longer sufficient in this dynamic landscape.

Adopting a zero-trust security model enables organisations to build a resilient and adaptable framework that is designed to handle future threats. By continuously verifying user identities, validating device integrity and enforcing least-privilege access, Zero Trust provides a proactive defence strategy that scales with technological change and organisational growth.

Regulatory Compliance

Meeting regulatory requirements is a critical component of any organisation’s cybersecurity strategy. With the increasing complexity of global data protection laws, such as GDPR, CCPA and HIPAA, among others, organisations must ensure that they handle sensitive data in a secure and compliant manner.

Implementing Zero-trust within an Identity and Access Management framework supports regulatory compliance by providing robust access controls, detailed audit logs and continuous monitoring. This ensures that only authorised users and secure devices can access protected resources in alignment with compliance mandates.

Key Components of Zero-trust Identity and Access Management

Here are some key components of Zero-trust identity and access management.

User Authentication and Authorisation

One of the key components of Zero-trust IAM is user authentication and authorisation. The purpose of this component is to employ robust user authentication and verification protocols. Various multi-faceted authentication processes are employed, including multi-factor authentication, biometric authentication and others.

Network Access Control and Data Segmentation

Controlling how users and devices access the network is essential in a Zero-trust model. Network Access Control evaluates the security posture of devices before granting them network access. 

Once inside, data segmentation, also known as micro-segmentation, ensures that users can only reach the specific data or services they are authorised to use. 

This limits the potential damage in case of a breach and helps contain threats within isolated segments of the network.

Continuous Monitoring and Behavioural Analytics

Zero-trust IAM is not a one-time verification process; it requires constant observation of user behaviour and system activity. Continuous monitoring enables real-time visibility into access patterns and potential threats. Behavioural analytics helps identify unusual or risky activity by comparing it to established norms. 

This ongoing scrutiny enables the quicker detection of anomalies and a faster response to potential security incidents, thereby reducing the likelihood of a successful attack.

Roadmap for Identity and Access Management

A well-structured Identity and Access Management roadmap provides a strategic path to securing digital identities, managing user access and enforcing consistent security policies across the organisation.

Assessment and Planning

Begin by assessing your current identity and access controls. Identify gaps, risks and compliance requirements. Define IAM objectives aligned with business goals, such as enhancing security, enabling secure remote access and meeting regulatory standards.

Isolate user interactions or Micro-segmentation.

Using an Active Directory User Group, intelligent micro-segmentation can isolate user access. It essentially means setting up Software-Defined Perimeters (SDP) based on user groups, locations, or logically grouped applications.

Multi-Factor Authentication

Previously, ‘Two-Factor Authentication’ was considered a very basic requirement. However, the Zero Trust Model has evolved to vet multiple points to establish identity and grant relevant access to areas of the network. Call it MFA, 2FA, or third-factor authentication; they are all essential for Zero Trust.

Follow Least Privilege Principles

Companies must determine where the sensitive data resides. Thereafter, grant users the least amount of access necessary for their roles.

Web Security for Blocking Potential Phishing Attacks

Even the most vigilant and cautious of employees can fall victim to a cleverly crafted phishing attack. A Zero Trust Model also includes web security gateways that block user access to any malicious websites.

User and Entity Behaviour and Analytics

Employees typically have a set pattern of operation and active hours during which they work. Using Identity and Access Management, a Zero-trust Model can spot anomalous or suspicious actions carried out from legitimate accounts.
