IAM or Identity Access Management - is essential in the 21st century.

For any company with a database or information system - data breaches can cost an average of 4.88 Million USD according to a 2024 report by IBM.

IAM software removes this problem completely and this article will cover how.

What is IAM?

Identity and Access Management (IAM) is a framework that lets only the right people in a company access the tools they need while keeping unauthorized users out. It combines policies, processes, and technologies to manage and secure digital identities. 

This adds passwordless authentication like biometrics, OTP, or device-based authentication to your security.
This keeps you protected from ransomware, data breaches, and hackers looking to exploit your system. It also prevents EXPENSIVE fines from data privacy laws like HIPAA, GDPR, or CCPA.

Moreover, a lot of advanced IAM software allows you to add this to your full tech stack alongside single sign-on! This helps you to log in to software in one go but keep them all secure when doing this!

Why is IAM Important? 

Although the simple answer is security, the reality is that using or not using an IAM affects your business in very specific ways. Want to understand why you need Identity and access management software? Then, you first need to understand what helps safeguard and avoid: 

  • Access Control: Ensures that only authorized users and approved tools or platforms (through APIs or integrations) can access sensitive data and applications, mitigating the risk of breaches and unauthorized activity.
  • Compliance Support: Facilitates adherence to regulatory requirements by enforcing access policies and maintaining auditable logs for frameworks like GDPR, HIPAA, and ISO 27001.
  • Lower Chances of Insider Threats: Implements the principle of least privilege, limiting users’ permissions to only what’s necessary, and reducing risks from malicious or compromised insiders.
  • Centralized Security Management: Provides a unified platform to manage identities, roles, and permissions across all systems, enhancing consistency and reducing errors.
  • Better User Lifecycle Management: Simplifies onboarding, role assignment, and offboarding processes, ensuring employees and systems always have the appropriate level of access.
  • Improved User Productivity: Features like Single Sign-On (SSO) and automated provisioning reduce login complexities, enabling users to focus on their tasks without frequent interruptions.
  • Protection Against Credential-Based Attacks: Strengthens security with multi-factor authentication (MFA) and risk-based access controls, making it harder for attackers to exploit stolen credentials.

Basic Components of IAM

To have an Identity and Access Management tool that is reliable, you need to look out for the same features that balance both security and user experience. Aside from this, keep in mind your company, scalability and flexibility in the longrun. We’ve listed some features that are non-negotiable in your IAM tool.

1. Adaptive MFA Authentication

Multi-factor authentication doesn't have to be a hassle - modern adaptive MFA systems are smart enough to know when extra security checks make sense and when they don't. The system looks at things like where you're logging in from and what device you're using to make quick decisions about security needs. This means you get strong protection against unauthorized access without having to jump through unnecessary hoops every time you need to log in.

2. Single Sign-On 

We've all felt frustrated managing multiple passwords for different systems at work. Single Sign-On solves this everyday headache by letting you log in just once to access all your work applications and systems. Not only does this save time and reduce frustration, but it actually makes your accounts more secure since you only need to protect and remember one strong set of credentials instead of many.

3. AI Automation

Getting the right access to do your job shouldn't be complicated. Modern authorization systems use AI to understand work patterns and suggest appropriate access levels automatically. This means administrators spend less time manually adjusting permissions, and everyone gets the access they need when they need it. The system helps prevent both over-privileging and access bottlenecks by learning from how people actually work.

4. Directory-Sync

When organizations grow, keeping everyone's information up-to-date across different systems becomes crucial. Directory-sync ensures that when someone's role or status changes, that information updates everywhere instantly. This real-time synchronization prevents the confusion and security risks that come from outdated or conflicting user information across different systems.

5. Password Management

Password management has evolved beyond simple storage - modern systems actively help create and manage secure access. Instead of expecting users to create and remember complex passwords, these tools handle the heavy lifting of generating and securely storing strong, unique credentials for every application. This makes life easier for users while significantly improving security.

6. Compliance Management

Staying compliant with data protection regulations is essential for modern businesses. Compliance management features actively track how your system handles sensitive data and automatically enforce security policies. This ongoing monitoring means you're always prepared for audits and can prove you're protecting data appropriately.

7. Automatic or Quick User Provisioning and De-provisioning

When people join or leave an organization, their system access needs to change immediately. Automatic provisioning systems handle this process smoothly, ensuring new team members can start working right away and departed employees lose access immediately. This automation prevents both productivity delays and security risks.

8. Privileged Access Control

Through ABAC and RBAC ProtocolsHigh-level system access needs careful management. ABAC and RBAC protocols provide flexible ways to control this access based on different factors - ABAC looks at specific attributes about users and situations, while RBAC assigns access based on job roles. These systems work together to ensure sensitive systems stay protected while remaining accessible to those who need them.

9. Impersonation or Role Delegation

Sometimes administrators need to troubleshoot issues by seeing exactly what a user sees, or temporarily grant someone else certain permissions. Impersonation and role delegation features let this happen securely while keeping clear records of who did what. This helps solve problems quickly while maintaining security.

10. Zero Trust Framework and Passwordless Authentication

Security needs have evolved beyond simple passwords. Zero Trust systems verify every access attempt, regardless of who makes it, while passwordless authentication uses more secure methods like biometrics or security tokens. Together, these approaches create stronger security that's actually easier to use.

11. Brute Force Protection

Online attacks often involve repeatedly trying different passwords to break into accounts. Brute Force Protection actively watches for these patterns of repeated login attempts and stops them before they succeed. This creates an essential layer of defense against one of the most common types of cyber attacks.

How Does IAM Work?

In simple words - it controls access. But from a process standpoint there a multiple steps that take place once the user is onboarded and put in place to make sure that security is maintained no matter the changes to your workforce.

  1. IAM (Identity and Access Management) begins by identifying users through unique credentials, such as usernames and passwords, biometrics, or security tokens. It confirms the identity of users using authentication methods to verify their legitimacy.
  2. Once a user is authenticated, IAM evaluates their role and associated permissions. This process determines what resources they can access and what actions they are allowed to perform.
  3. Policies and rules within the IAM system govern access control to maintain security. These rules are regularly updated to align with organizational needs and compliance requirements.
  4. IAM also monitors user activity to detect and prevent unauthorized access or suspicious behavior. It logs events for auditing and troubleshooting purposes to strengthen security and transparency.

IAM and Compliance Regulations 

Regulatory fines are expensive! IAM compliance removes this headache almost completely. One of the major things IAM takes care of is meeting data privacy compliance as well as specific industry standards around access to information and customer data.

  • Many regulations, such as GDPR, HIPAA, and PCI DSS, require strict access controls to protect personal and financial data. IAM enforces these controls by verifying user identities and limiting access to authorized personnel only.
  • Audit trails generated by IAM systems help demonstrate compliance during regulatory reviews. These logs provide detailed records of who accessed what, when, and how, aiding in accountability.
  • IAM supports compliance by implementing principles like least privilege and role-based access control (RBAC). These measures minimize unnecessary access, protecting sensitive systems from internal and external threats.
  • Regular updates to IAM policies help address evolving regulatory requirements. This ensures that systems remain secure and aligned with the latest compliance mandates.

IAM Tools and Technologies

When talking about IAM tools and tech - you need to think of frameworks that help you control access. In terms of this, different sub-genres in IAM can help you maintain and manage this accessibility with ease. Some IAM tools and functionality they put in place are as follows:

  • Role-Based Access Control: RBAC functions like a sophisticated permissions system. Consider how a hospital operates - doctors, nurses, and administrative staff each need access to different parts of patient records. Role-based access control (RBAC) creates these distinct sets of permissions, ensuring everyone can do their job effectively while keeping sensitive information secure.
  • Privileged Access Management: PAM serves as a temporary access vault for our most critical systems. When someone needs elevated access, Privileged access management grants it for a specific duration and monitors its usage, much like how a bank vault might be accessed only at certain times under supervision.
  • Identity Governance and Administration: This feature works like a digital human resources department, managing who has access to what across our entire organization. Identity governance and administration keep track of permissions, regularly review who should access which resources, and ensure we're following all necessary regulations.
  • Biometric Authentication: This is a move toward using your unique physical characteristics as your passwords. Rather than remembering complex combinations of letters and numbers, biometric authentication lets you use your fingerprints, faces, or other distinctive traits to prove who you are.
  • Federated Identity Management: It allows seamless collaboration across organizational boundaries. Federated identity management allows people to use their existing credentials to access resources in partner organizations, similar to how a passport lets us travel between countries while maintaining security.
  • Cloud-Based IAM Solutions: These types of solutions provide flexible, scalable identity management that works wherever our employees are located. These cloud-based IAM  adapt to our changing needs, whether our workforce is in the office, at home, or spread across the globe.

Implementing IAM in the Enterprise

Putting an IAM in place in your company can vary based on enterprise, business model, and size. Overall, however, there are some checkpoints and tools that ALL businesses can benefit from which include: 

  • You need to understand their specific needs and create clear guidelines about who should have access to what resources. This foundation helps everyone understand their responsibilities and rights within the digital environment.
  • When selecting IAM tools, organizations must consider their unique requirements, including how many employees they have, what kinds of systems they use, and how they need to grow in the future. The chosen IAM tools should work smoothly with both traditional office systems and cloud services.
  • Implementing role-based access starts with understanding how different jobs require different levels of access. By carefully mapping out these requirements, companies can make sure everyone has exactly what they need to work effectively - no more, no less.
  • Adding multi-factor authentication using your IAM tool strengthens security across your company. While it might seem like an extra step, this additional layer of protection has become essential in our current digital landscape where cyber threats constantly evolve.
  • Automating the process of granting and removing access as employees join, move within, or leave the organization reduces human error and ensures consistency. This automation helps maintain security using your IAM tool while making the process more efficient for everyone involved.
  • Regular monitoring and reviewing of access patterns helps identify potential security issues before they become problems. These reviews help make sure that access permissions in your IAM framework remain appropriate and comply with various regulations and business requirements.

How to Overcome Barriers in Implementing IAM Solutions? 

Putting any tech in place comes with its own set of challenges. IAM solutions are no stranger to these challenges - especially in larger companies. To help you out, we’ve listed some of the most common roadblocks and how you can overcome them.

1. Scaling for Large Enterprises

When companies grow across multiple locations, managing digital identities becomes increasingly complex, like trying to coordinate security for hundreds of interconnected buildings simultaneously. Additionally, different regions often have unique requirements and legacy systems that need special consideration.

Solution: Opt for IAM solutions with robust scalability options and leverage cloud-based architectures to manage distributed environments efficiently.

2. Security Concerns During Implementation

Security concerns during implementation would typically occur during the transition period between old and new identity management systems.

During this stage, there are multiple, potential weak points, a lot like replacing locks in a building while people still need to move in and out. Cybercriminals often specifically target companies during these vulnerable transition phases, knowing that security measures might be temporarily weakened.

Solution: Conduct thorough risk assessments, implement strong encryption and monitoring during the rollout, and in doing this use sandbox environments for testing. Here, using governance and IAM tools can be a straightforward method to solve this as well.

3. Integration Challenges

Existing systems and applications may not be compatible with new IAM solutions. The situation becomes even more complicated when dealing with custom-built internal applications that weren't designed with modern authentication methods in mind.

Solution: Choose IAM tools with flexible APIs and integration capabilities, and perform a phased implementation to address compatibility issues incrementally.

4. Compliance Requirements

Companies often find themselves overwhelmed by the maze of regulatory requirements that vary by industry, region, and data type, creating a complex web of obligations to navigate. The challenge intensifies when regulations conflict across different jurisdictions or when new requirements emerge during implementation.

Solution: Work with compliance experts to design IAM policies that satisfy regulations, and use IAM solutions with built-in compliance features.

5. Complexity of Role Definition

Creating appropriate access levels across an organization requires understanding countless job functions, responsibilities, and security requirements, similar to mapping out who should have keys to which rooms in a massive complex. The task becomes even more challenging when roles overlap or change frequently based on projects or organizational shifts. 

Solution: Use role-mining tools like RBAC software and conduct workshops with stakeholders to collaboratively define roles, ensuring alignment with business needs.

6. High Implementation Costs

The initial investment required for reliable identity management solutions often causes companies to hesitate, particularly when considering the combined costs of software, infrastructure, and expertise needed. Small and medium-sized enterprises especially struggle with justifying these expenses against their immediate operational needs. 

Solution: Start with scalable, cloud-based IAM solutions that reduce upfront costs and align with budget constraints while demonstrating ROI.
