What is Identity-First Security and Why it is an Important Security Strategy
Share
As businesses increasingly migrate their operations to the Cloud, traditional network perimeter security measures are proving inadequate. In today’s landscape, threats can emerge from any location—inside or outside the conventional network boundaries. To effectively protect digital assets, organizations must transition to an identity-first security approach, making Identity and Access Management (IAM) a fundamental element of their cybersecurity strategy. This shift can be complex, particularly for organizations still navigating the basics of IAM implementation.
IAM is crucial for ensuring that access rights are appropriately managed and granted at the necessary time. With the rise of Web3, Industry 4.0, artificial intelligence, and hyper automation, the scope of IAM must expand to secure a growing number of identities and systems while mitigating potential attacks. The only viable solution for companies is to implement robust IAM security measures that provide continuous, real-time, context-aware identity and access control.
What is Identity-First Security
Security shifts the focus. As the boundaries of traditional perimeters become increasingly blurred—due to the rise of cloud computing, mobile devices, and remote work—there’s a growing need for a security model that adapts to these changes. Additionally, as organizations move towards empowering individuals closer to tasks for quicker and more autonomous responses, security leaders are prompted to rethink how security is managed.
Identity-First Security introduces a more granular and context-aware approach, centered on identities and their associated attributes. This model leverages technologies and practices such as multi-factor authentication (MFA), identity and access management (IAM), privileged access management (PAM), and customer IAM (CIAM).
By positioning identity at the heart of the security framework, organizations can achieve a higher level of trust and control over their systems and resources, ensuring a more secure environment.
The 3 C’s of Gartner’s Identity-First Security Approach
Gartner’s Identity-First Security approach emphasizes three key principles, known as the 3 C’s: Consistent, Context-Aware, and Continuous. These principles are crucial for effectively implementing identity-first security, ensuring that identity security is managed with precision and rigor.
Understanding the 3 C’s
- Consistent – Regular and ongoing efforts
- Context-Aware – Understanding the circumstances surrounding the use of an object
- Continuous – Uninterrupted, ongoing tasks
But how do these principles apply to identity-first security? While our security perimeter includes on-premises firewalls and cloud environments, it fundamentally begins with identities. By securing these identities and placing strict controls around them—such as removing standing access, adhering to the principle of least privilege, and enforcing Just-in-Time (JIT) access—organizations can significantly enhance their overall security posture. In any security framework, identity security must be the top priority.
- The First “C”: Consistent
The first principle is Consistency, which involves the continuous identification and protection of both new and existing identities, including those that may not be immediately apparent. As employees join, leave, or change roles within an organization, their access rights must be regularly updated to reflect these changes. Similarly, as machines and services are deployed or retired, they too require vigilant management of their access permissions. Given the frequent changes to both human and machine identities within an organization, maintaining security requires:
- Consistent identification of all identities within the organization.
- Consistent management of those identities, ensuring they have appropriate access.
- Consistent testing of the systems, processes, and policies that protect these identities.
- The Second “C”: Context-Aware
The next principle is Context-Awareness, which is essential for understanding how identities are used within an organization. This involves asking key questions to gain insight into the context of each identity, such as:
- How are these identities utilized?
- What types of accounts do they have access to?
- Is this access necessary?
These identities could be human or machine-based, and they may operate within various environments, such as data centers, infrastructure servers, network devices, or cloud platforms like AWS, Azure, and Google Cloud. Contextual awareness also includes understanding the typical behavior of these identities, including the devices they use, their normal activities, and the times and locations from which they operate. This understanding is critical for accurately securing identities and detecting anomalies that could indicate a compromised identity.
- The Third “C”: Continuous
The final principle is Continuity, which requires that consistency and contextual awareness become ingrained habits in identity security practices. You may wonder, “How can this be achieved?” If your organization already excels in the first two principles, then the solution is straightforward: Keep doing what you’re doing.
For organizations still striving to master these principles, the task may seem overwhelming, but there is hope. The key is not to rely on manual processes or to develop proprietary software to manage this complex task. Instead, the cybersecurity industry offers a variety of tools designed to help organizations achieve continuous identity security.
By leveraging these tools and adhering to the principles of Consistent, Context-Aware, and Continuous identity management, organizations can establish a robust identity-first security framework that effectively protects against modern threats.
Benefits of Identity-First Security
- Stronger Authentication
Implementing multi-factor authentication (MFA) alongside technologies like adaptive authentication significantly reduces the risk of unauthorized access. This approach strengthens the protection of sensitive information by adding layers of security that make it more difficult for malicious actors to bypass. - Granular Access Control
Identity-First Security enables the implementation of fine-grained access controls based on user identities and their associated attributes. By adhering to the principle of least privilege, this approach ensures that users only have the access rights necessary for their roles, thereby minimizing the risk of privilege misuse and unauthorized access. - Context-Aware Security
Identity-First Security leverages contextual information, such as a user’s location, device, and behavior patterns, to assess security risks in real time. This adaptive approach allows for the application of appropriate security measures that enhance protection while minimizing disruptions for legitimate users. - Improved Visibility
By linking actions to specific identities, Identity-First Security enhances visibility into user activities. This capability allows organizations to more effectively track and audit user actions, detect suspicious behavior, and hold users accountable for their actions, thereby discouraging insider threats. - Streamlined User Experience
Identity-First Security can improve the user experience by offering features like passwordless authentication, single sign-on (SSO) solutions, and self-service options. These functionalities simplify access while maintaining high security standards, making it easier for users to interact with systems without compromising safety. - Compliance and Regulatory Requirements
Many compliance standards and regulations, such as the General Data Protection Regulation (GDPR), mandate the implementation of strong identity and access controls. Identity-First Security assists organizations in meeting these requirements, ensuring that they can demonstrate compliance and maintain trust with stakeholders. - Reduced Attack Surface
By placing identity at the center of the security framework, Identity-First Security reduces the attack surface available to potential threats. Strong authentication and access controls help mitigate the risk of unauthorized access and data breaches, making it harder for attackers to exploit vulnerabilities. - Scalability and Flexibility
Identity-First Security solutions are designed to scale with an organization’s growth and adapt to evolving security needs. This scalability ensures that as an organization expands, its security posture remains robust and responsive to new challenges.
Component Requirements and Benefits for Identity-First Security Implementation
- Identity Verification
This component focuses on thoroughly validating the identity of users, devices, or entities before granting access to resources. Identity proofing is crucial during the initial linking of an identity to a person and should be re-verified as needed. By incorporating multi-factor authentication (MFA) and digital certificates, the risk of unauthorized access due to compromised credentials is significantly reduced.
Benefits:
Strengthened authentication processes ensure that only verified identities gain access, thereby enhancing overall security.
- Access Control
Strict access controls should be implemented based on user roles, responsibilities, and the principle of least privilege. Individuals should only be granted the minimum level of access necessary to perform their tasks.
Benefits:
This allows organizations to implement granular access controls, minimizing the permissions granted to users and thereby reducing the potential attack surface.
- Adaptive Authorization
Adaptive and context-aware authorization mechanisms should be employed, taking into account factors such as identity, device, location, time, behavior, and current threats. These mechanisms assess the risk associated with each access request before granting it.
Benefits:
By dynamically adjusting access and authentication requirements based on real-time risk assessments, this approach enhances security without compromising user experience.
- Continuous Monitoring and Response
User and entity behavior should be continuously monitored and analyzed to detect anomalies or suspicious activities. Real-time risk associated with each action should be re-evaluated, with re-authentication or stronger verification required when necessary.
Benefits:
Continuous monitoring provides better visibility into activities, enabling organizations to detect and respond to suspicious behavior in real time.
- Identity Governance and Administration
Policies and procedures should be established to govern the entire lifecycle of digital identities, from onboarding to management and de-provisioning. This ensures secure identity management throughout its lifecycle.
Benefits:
Robust identity governance practices reduce the risk of orphaned or unauthorized accounts by managing identities securely throughout their lifecycle.
- Privilege Access Management
Elevated privileges should be managed and controlled to ensure users have the necessary permissions for their roles without unnecessary access to sensitive resources.
Benefits:
Effective management of elevated privileges reduces the risk of privilege misuse or abuse, ensuring users have only the access required for their specific roles.
- Integrate IAM with Other Security Measures
IAM should be integrated with other security technologies and measures, such as encryption, endpoint security, and threat intelligence, to create a comprehensive and layered security infrastructure.
Benefits:
This integration adapts well to dynamic and complex IT environments, including cloud services and mobile devices, providing a flexible and scalable security framework.
Identity-First Security Framework
The required components for identity-first security implementation can be realized through a structured framework that integrates different IAM and security products. A central control layer, such as an Identity Integration and Orchestration Platform, manages communication between access requests and prescribed least privilege access to protected data and resources. This flexible architecture extends IAM capabilities to other security controls and systems, supporting a holistic Zero Trust implementation.
A successful identity-first implementation requires a holistic transformation across people, processes, and technology, not just a focus on technology alone. This framework model helps assess the maturity of implementation and integration across all identity and security ecosystems.
