Identity and Access Management Consulting Services

Identity and access management (IAM) defines who can sign in to systems and what each individual or application is permitted to do. It effectively translates security policies into daily operational practice across the organisation.

Key concepts

• Authentication verifies that a user is who they say they are. Standard methods include passwords, multi-factor authentication, and passkeys.
• Authorization determines the actions a signed-in user can take. Role-based access control organises permissions according to job functions.
• Single sign-on enables users to access multiple applications using a single login.
• Lifecycle management handles the addition, modification, and revocation of access as staff join, transition roles, or depart.

Areas of benefit

• New employees can be provisioned with the correct accounts on their first day, avoiding delays caused by manual request processes.
• Access rights can be revoked immediately upon an employee's departure, addressing a common 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 used by applications can be assigned to specific owners and governed by expiry rules.

Considerations and trade-offs

• Security vs convenience: Additional login steps create friction, but adaptive rules can restrict these to high-risk sign-ins only.
• Centralised vs separate directories: Using a single identity provider simplifies administration but also creates a critical system that must remain highly available.
• Cloud vs self-hosted: Cloud-based identity services reduce maintenance overhead, while self-hosted options offer greater control over data residency and customisation.
• Detailed vs simple roles: Granular roles limit exposure but require more effort to maintain.

Organisational considerations

• The principle of least privilege dictates granting only the access required for a specific task, working best when paired with regular reviews.
• Administrator accounts require stronger safeguards and more rigorous monitoring compared to standard user accounts.
• Legacy applications may not support modern standards such as SAML or OpenID Connect; integration work should be planned and budgeted accordingly.
