How zero trust and IAM security work together to enhance cybersecurity

by | Jun 14, 2024 | Public Relations

In a network with no boundaries, understanding who is on the network and why they are there is critical to maintaining organizational security. That’s why a strong policy is fundamental to successfully deploying zero trust and IAM security infrastructure.

Zero trust simply means consistently verifying authorized users as they move about their networks and granting each user the relevant possible privileges when accessing sensitive areas, documents, or files. IAM manages user identities and controls access, ensuring only authorized users can access sensitive information.

When combined, zero trust and identity and access management create a strong defense against security breaches. This integration improves security by implementing multi-factor authentication, enforcing least privilege access, and continuously monitoring user activities. In this article, we will understand how these two solutions work together to deliver safe, secure, and streamlined access management.

Understanding zero trust: A comprehensive approach to modern security

Zero trust is a security model that shifts the focus from conventional perimeter-based security to a more granular, identity-based approach. Unlike traditional security measures that consider everything inside the network to be trustworthy, zero trust runs on the principle of “never trust, always verify”. This model always requires stringent identity verification for every user and device attempting to access resources, regardless of whether they are inside or outside the network. 

Zero trust involves various key components. First, it accentuates the validation of user identities through multi-factor authentication. This ensures access is granted only after verifying multiple factors, such as passwords, biometrics, or security tokens. Additionally, zero trust enforces the principle of least privilege access, allowing users the minimal level of access required to perform their tasks. This reduces the risk of unauthorized access and limits potential damage from compromised accounts.

Microsegmentation is another essential aspect of zero trust. It involves dividing the network into smaller, isolated segments to control and restrict access to high-risk data and resources. This approach reduces lateral movement within the network, making it difficult for attackers to spread if they gain access. By implementing these strategies, zero trust provides a strong and flexible framework that enhances security and mitigates risks in modern IT domains.

Exploring identity and access management (IAM): A key to secure access control

Identity and access management is a framework of policies and technologies developed to ensure the right users have the required access to technology resources. IAM manages and controls an organization’s user identities, authentication, and authorization. By centralizing and automating these processes, IAM improves security, enhances user experience, and ensures compliance with regulatory requirements.

IAM includes various critical components. User provisioning and deprovisioning are essential functions, enabling administrators to create, manage, and remove user accounts efficiently. Authentication mechanisms, such as single sign-on and multiple authentication, verify user identities and ensure that only authorized users can access sensitive information. Authorization policies determine what specific resources and data a user can access based on their role and permissions within the business.

Another key component of IAM is auditing and reporting. IAM solutions monitor and log user activities, providing comprehensive reports for compliance and security auditing purposes. This enhanced visibility helps businesses detect and respond to suspicious activities and potential security breaches quickly. By implementing IAM, businesses can achieve a higher level of security, streamline access management, and protect sensitive information from unauthorized access.

How zero trust and IAM work together

Zero trust and identity & access management together form a powerful security framework. By integrating continuous verification with strong access control, they enhance protection against modern threats.

Continuous authentication and verification

Zero trust and IAM work together to ensure every user and device is consistently authenticated and verified before accessing any resources. Zero trust’s main idea, “never trust, always verify,” requires constant validation of all access requests. IAM supports this by managing user identities and providing the required authentication mechanism. This continuous verification helps identify and mitigate potential security threats effectively, ensuring access is given only to verified users.

Enhanced security through multi-factor authentication

The essential component of integrating zero trust with IAM is the use of multi-factor authentication. MFA requires users to authenticate their identities using multiple methods. This approach significantly reduces the risk of unauthorized access, even if one factor is compromised. IAM solutions initiate the deployment and management of MFA, making it easier for businesses to enforce strong authentication policies. By using MFA, organizations can improve their security posture and protect sensitive data from malicious attacks.

Enforcing least-privilege access

The principle of least privilege access is central to both zero trust and IAM security. IAM defines and manages user roles and permissions, ensuring users have the minimum access necessary to perform their tasks. Zero trust regularly assesses and validates these access requests, enforcing strict access controls. This combined approach reduces the risk of internal threats and limits potential damage from compromised accounts. Businesses can reduce the attack surface and enhance overall security by granting users only the permissions they need.

Real-time response and continuous monitoring

Continuous monitoring is a critical aspect of integration between zero trust and IAM. Identity and access management tracks user activities and generates detailed logs, providing valuable data for security audits and compliance. Zero trust frameworks use this data to detect and respond to suspicious activities in real time. For instance, if suspicious login attempts or access patterns are detected, the system can trigger additional authentication steps or restrict access until the activity is verified. This real-time monitoring and response capability helps businesses quickly mitigate potential security incidents.

Practical applications

The effective benefits of integrating zero trust and IAM can be seen in various industry scenarios. For instance, a financial institution that will implement this combined approach will ensure that only authorized persons can access sensitive financial data. Using MFA and least privilege access significantly reduces the risk of data breaches. Continuous monitoring allows the business to detect and respond to unusual activities promptly. 

Similarly, a healthcare organization can protect patient information by adopting zero trust and IAM strategies, ensuring compliance with regulatory standards. These examples can illustrate the effectiveness of zero trust and IAM integration in real-world scenarios, highlighting its importance for modern enterprises.
