What is Identity Security?
Identity security refers to a comprehensive approach to safeguarding all forms of identities within an organization, whether human or machine, and whether they are related to regular or privileged access.
Given that any type of identity can potentially grant adversaries access to sensitive resources, it is vital to authenticate each identity accurately and authorize access requests in a way that maintains security. This helps prevent many digital threats.
Identity security is a critical component of an organization’s overall security architecture. Still, it should be part of a larger cybersecurity strategy that includes endpoint security, IT security, cloud security, and other elements. Additionally, identity security posture management solutions should seamlessly integrate with an organization’s existing Identity and Access Management (IAM) tools and processes and, if present, adhere to the principles of Zero Trust.
Identity-driven breaches have become a prevalent threat, with statistics showing that as many as 80% of breaches are linked to identities. These attacks often bypass traditional cybersecurity defenses by exploiting compromised credentials to move laterally and conduct more devastating attacks. Detecting these identity-driven attacks is particularly challenging because adversaries often mimic legitimate users, making it difficult to distinguish between normal user behavior and malicious activity using traditional security tools.
Identity Security Includes The Following:
Authenticating:
Authenticating every identity accurately is a fundamental component of identity security. It involves verifying the legitimacy of an identity seeking access to a system, application, or resource. Effective authentication ensures that the identity is indeed who they claim to be.
- This can be achieved through various methods:
- Username and Password: The traditional method where users provide a unique username and a secret password.
- Biometric Authentication: Utilizing physical or behavioral characteristics like fingerprints, facial recognition, or voice patterns for identity verification.
- Multi-Factor Authentication (MFA): Requiring users to provide two or more forms of authentication, such as a password and a one-time code sent to their mobile device.
- Smart Cards or Tokens: Using physical tokens or smart cards to provide additional proof of identity.
- Single Sign-On (SSO): Allowing users to log in once and access multiple resources without repeated authentication.
Authorizing:
Authorizing identities with the proper permissions is the next step in identity security. Once an identity is authenticated, it is essential to determine what level of access or privileges it should have within the system. Authorization ensures that the identity can only perform actions or access resources aligning with their roles and responsibilities.
- Key components of authorization include:
- Role-Based Access Control (RBAC): Defining access permissions based on organizational roles. Users are assigned roles, and these roles determine their access.
- Attribute-Based Access Control (ABAC): Access decisions are based on attributes related to the identity, the resource, and the environment.
- Permission Policies: Creating policies that specify what actions an identity can perform on specific resources.
Access:
Providing access for identities to privileged assets in a structured manner is an integral part of identity security. This component ensures that authorized identities can access the resources they need to fulfill their roles and responsibilities.
- The access component involves:
- Access Control Lists (ACLs): Defining and managing permissions lists that specify which identities can access specific resources.
- Resource Allocation: Allocating resources in a controlled manner, ensuring access is granted based on authorization policies.
- User Provisioning and Deprovisioning: Managing the onboarding and offboarding of identities, ensuring that access is granted when needed and revoked when no longer required.
- Structured access control prevents unauthorized access, maintains data integrity, and protects sensitive assets.
Auditing:
Auditing completes the cycle of identity security. It ensures that the entire process of authenticating, authorizing, and providing access is sound and accountable. Auditing is the practice of monitoring and recording identity-related activities and access to critical resources.
- Key components of auditing include:
- Logging and Event Recording: Keeping detailed logs of identity-related activities, including login attempts, access requests, and system changes.
- Security Information and Event Management (SIEM): Utilizing SIEM systems to centralize and analyze logs, enabling the detection of anomalies or security incidents.
- Compliance Monitoring: Ensuring that the organization adheres to industry and regulatory compliance requirements by tracking and reporting on access and activities.
- Incident Response: Using audit data to investigate and respond to security incidents or breaches, to mitigate damage and prevent future occurrences.

How is Identity Security Different from Zero Trust?
Zero Trust is not a specific solution but a security approach based on the principle of “never trust, always verify.” Identity Security serves as a foundational component for achieving Zero Trust. It ensures that every user’s identity is verified, their devices are validated, and their privileged access is continually limited and monitored.
In essence, Identity Security serves as the linchpin of Zero Trust, establishing the foundation upon which the Zero Trust principle of continuous verification is built. By rigorously verifying user identities, assessing the security of their devices, and closely monitoring privileged access, Identity Security empowers organizations to embody the Zero Trust philosophy.
