In our continuing series on online protection our resident IT Expert, Colin Middleton, takes a closer look at IAM.

What is IAM?
Identity and Access Management (IAM) is the framework of policies and technologies that ensures the right individuals have the right access to the right resources—at the right time. It controls who is authenticated (proved who they are) and authorised (allowed to do something) within an organisation’s systems.

Why It Matters
Without strong IAM, unauthorised users—including hackers—can gain access to sensitive data or critical systems. IAM helps prevent data breaches, enforces compliance, and supports secure remote working.

Key Components of IAM:

• User Authentication: Verifies the identity of users (e.g., through passwords, biometrics, or multi-factor authentication).
• Role-Based Access Control (RBAC): Grants access based on a user’s role and responsibilities.
• Lifecycle Management: Ensures user accounts are created, modified, or removed as needed (e.g., when someone joins or leaves).
• Single Sign-On (SSO): Allows users to log in once and access multiple systems securely.
• Multi-Factor Authentication (MFA): Adds an extra layer of security beyond just passwords.

Tips for Better IAM:

• Enforce MFA for all users—especially admins and remote users.
• Apply the principle of least privilege: users should only have the access they absolutely need.
• Regularly audit and clean up inactive or unnecessary accounts.
• Use SSO where possible to reduce password fatigue and improve security.
• Monitor IAM logs for unusual login activity or access requests.

Did You Know?
Over 80% of hacking-related breaches involve compromised credentials. IAM is your first line of defence.
