I was trying to learn and understand differences between IAM, IGA and PAM. My colleague Anant Sharma helped me understand the concepts.
Per Gartner, IAM:
The discipline that enables the right individuals to access the right resources at the right times for the right reasons. IAM systems enable your organization to manage employee apps without logging into each app as an administrator.
Difference between IM and AM:
Identity Management confirms that you are who you claim to be and stores information about you. An identity management database holds information about your identity - for example, your job title and your direct reports - and authenticates that you are, indeed, the person described in the database.
Access Management uses the information about your identity to determine which software suites you're allowed access to and what you're allowed to do when you access them.
IGA (Identity Governance & Administration):
IGA is both a policy framework and set of security solutions that enable organizations to more effectively mitigate identity-related access risks within their business. IGA automates the creation, management, and certification of user accounts, roles, and access rights for individual users in an organization.
PAM:
PAM enables organizations to simplify how they define, monitor, and manage privileged access across their IT systems, applications, and infrastructure. Because administrator accounts have elevated privileges that can access valuable data and execute applications or transactions, often with little or no tracking control, it can be very difficult to manage privileged accounts. PAM solutions centralize management of administrator profiles and ensure least privilege access is enforced to give users only the access they need.
Per Gartner, difference between IAM and IGA:
IGA differs from IAM in that it allows organizations to not only define and enforce IAM policy, but also connect IAM functions to meet audit and compliance requirements.
While IAM and IGA focus on wider levels of user access for resources, systems, and applications across the organization, PAM primarily defines and controls access for privileged users.
For example, inappropriate and/or outdated access to enterprise resources is a common problem in IAM. A remote workforce, time-consuming provisioning processes, weak Bring Your Own Device (BYOD) policies and strict compliance requirements are some other identity management system challenges. These issues increase security risk and weaken organizations’ compliance posture. That’s why many organizations use IGA to meet the compliance requirements laid out in GDPR, HIPAA, SOX and PCI DSS.
