Identity and Access Management Consulting Services

Identity and access management (IAM) defines who is permitted to sign in to systems and outlines the specific actions each user or application is authorized to perform. It effectively translates security policies into practical, everyday operational realities across the organization.

Core concepts

• Authentication verifies that a user is indeed who they claim to be. Typical methods include passwords, multi-factor authentication, and passkeys.
• Authorization determines the capabilities of an authenticated user. Role-based access control organizes permissions according to job functions.
• Single sign-on enables users to access numerous applications using a single set of credentials.
• Lifecycle management governs the addition, modification, and removal of access rights as personnel join, change roles, or depart.

Where it is useful

• New hires can be provisioned with the appropriate accounts from day one, eliminating delays associated with manual requests.
• Access can be revoked immediately upon an employee's departure, effectively closing a frequent security vulnerability.
• Access reviews provide auditors with clear visibility into who can access sensitive systems and the rationale behind it.
• Service accounts and API keys utilized by applications can be assigned specific owners and expiration rules.

Trade-offs to consider

• Security versus convenience: Additional login steps can introduce friction. Adaptive rules offer a solution by applying strict measures only to high-risk sign-ins.
• Central versus separate directories: Utilizing a single identity provider simplifies administration, though it also designates a critical system that must remain highly available.
• Cloud versus self-hosted: Cloud-based identity services reduce maintenance burdens, while self-hosted solutions offer greater control over data location and customization.
• Detailed versus simple roles: Granular roles limit exposure but require more significant maintenance efforts.

What organizations should consider

• Least privilege involves granting only the access necessary for a specific task. This approach is most effective when paired with regular reviews.
• Administrator accounts require more robust protection and closer monitoring than standard user accounts.
• Legacy applications may lack support for standards such as SAML or OpenID Connect, necessitating planned and budgeted integration work.
