A password is no longer enough to protect a business.
Employees work from multiple locations, applications live in the cloud, mobile devices connect from anywhere, and automated systems, i.e. AI agents, are increasingly interacting with business data. As a result, Identity & Access Management (IAM) has become a critical part of modern cybersecurity.
IAM helps organizations control who can access what, when they can access it, and what they are allowed to do once they get there. CISA’s Zero Trust guidance specifically emphasizes giving users and other entities the right access at the right time without granting excessive permissions.
What Is Identity & Access Management?
Identity & Access Management is the combination of technologies, policies, and processes used to manage digital identities and control access to systems, applications, networks, and data.
In practical terms, IAM helps answer questions such as:
- Who is this user?
- Is this person really who they claim to be?
- What applications should they be able to access?
- What information should they see?
- What devices are they using?
- Should access change based on location or circumstances?
- What happens when an employee leaves the organization?
Instead of giving everyone broad access, IAM supports a more controlled approach based on identity, role, risk, and need. Providing a mechanism to establish clear boundaries in the workplace and the comfort that your digital information is protected at every level.
Why IAM Is Becoming More Important
Modern businesses have more points of access to their data now more than ever before. Employees, contractors, administrators, vendors, applications, cloud services, and automated systems may all require some level of access to business resources.
At the same time, attackers increasingly target legitimate credentials that already have familiarity in your system rather than simply trying to break through a network perimeter. In light of these adaptations, current cybersecurity discussions are putting greater emphasis on identity as a central security control, particularly as organizations adopt AI and other automated technologies. Ultimately, controlling identities is synonymous with protecting the network itself.
IAM and Multi-Factor Authentication
Multi-factor authentication (MFA) is one of the most recognizable components of an identity security strategy.
Instead of relying solely on a password, MFA requires additional verification before access is granted.
However, MFA should not be viewed as a complete IAM strategy. CISA notes that MFA is an important security control but must be part of a broader architecture that also addresses authentication, session security, access management, and other controls.
Effective IAM can combine:
- Multi-factor authentication
- Single sign-on (SSO)
- Role-based access
- Conditional access
- Privileged access management
- User provisioning and deprovisioning
- Identity monitoring
- Access reviews
- Passwordless authentication
IAM Supports Zero Trust Security
IAM is closely connected to Zero Trust Security.
Zero Trust assumes that access should not automatically be trusted simply because someone is inside a network. Instead, identity, device, permissions, and other context can be evaluated when determining whether access should be allowed.
CISA’s Zero Trust framework specifically identifies identity as a core pillar and recommends stronger authentication, tailored access, and continuous validation.
For businesses, that means moving away from:
You’re inside the network, so you’re trusted.
Toward:
You are authorized for this specific resource under these specific conditions.
Don’t Forget Former Employees
One of the simplest IAM problems can also be one of the most overlooked: access that should have been removed. When employees change positions or leave an organization, their access to email, cloud applications, files, VPNs, administrative systems, and other resources needs to be reviewed and removed appropriately.
Infinity Technology supports with effective identity lifecycle management to help organizations stay on top of their identity permissions.
The Next IAM Challenge: AI Agents
IAM is also entering a new phase as businesses increasingly deploy AI agents and other automated systems. Unlike a traditional employee account, an AI agent may interact with applications, data, and systems automatically. That creates new questions around non-human identities, permissions, authentication, monitoring, and least-privilege access. Furthermore, recent industry activity reflects this shift, with identity-security companies developing capabilities specifically for AI agents and other non-human identities.
