Identity and access management is a key component in ensuring the security of data. It can be used to protect companies against data breaches by providing a layer of security that protects information from unauthorized access. Find more about this concept along with why IAM is important and what is the best approach when implementing it.

What Is Identity and Access Management?

Identity and access management, often abbreviated as IAM, is a set of policies, processes, and technologies that help organizations manage the identities of individuals and devices, authenticate these identities for access to data or other resources and monitor who has accessed what.

How Does Identity and Access Management Work?

Through an identity and access management system, IT teams can properly control user access to critical data. The identity and access management framework of technologies works by providing the data on how individuals and their roles are identified in a system and what criteria are used to link these roles with users. It also supports the removal, addition, and update of users and roles, the distribution of access levels, and the management of user identities ’database.

What Are the Key Functions of Identity and Access Management Systems?

  • Access management: these encompass access policies that use SSO (single sign-on) and MFA (multi-factor authentication);
  • Identity governance: this has the role of user account lifecycle management, focusing on elements such as provision and entitlements related to those accounts;
  • Identity analytics: this IAM function works on the identification and consolidation of credential management;
  • User provisioning: this feature focuses on creating and assigning new user accounts automatically;
  • SSO (Single Sign-On): this function makes it easier for users to access services because it allows them to consolidate their passwords and credentials into a single account with robust password protection;
  • MFA (Multi-Factor Authentication) involves access control made up of many steps to properly assess the users’ authenticity and thus works on dramatically decreasing the risk of credential theft;
  • Risk-based authentication: this is a type of authentication that employs different algorithms that calculate how users’ actions might involve a potential risk. If some actions are scored as high-risk, these will be both blocked and reported;
  • Identity governance and administration (IGA): this function focuses on the control of entitlements which helps reduce the risk posed by privileged access or excessive access in general;
  • PAM (Privileged Access Management): PAM might be sometimes confused with IAM. However, the basic difference between them is that IAM takes care of the management of all users’ accounts, while Privileged Access Management focuses only on privileged accounts, so it is a category of IAM.

How Are IAM Systems Deployed?

Identity and Access Management systems can be delivered through various means. Here are they:

  • on-premises;
  • the cloud – by means of a third-party vendor;
  • through a hybrid model.

What Are Some Identity and Access Management Concepts?

When you look for the phrase “identity and access management” you might find throughout your search some other related concepts. Let’s shed some on the main IAM related terms:

  • Authentication: as the very name says, this has the role to authenticate users, services, and applications, so basically to check their identity;
  • Authorization: this concept defines how access is granted to the above instances to different resources;
  • Biometric authentication: biometrics are used in modern IAM systems to provide more precise authentication. They capture fingerprints, irises, faces, palms, gaits, voices, and, in certain circumstances, DNA, among other biometric features;
  • Provenance: a digital signature or an attestation record is used to check the identity or the authentic nature of an image or piece of code;
  • Behavioral authentication: companies can employ behavioral authentication to get considerably more detailed and examine keyboard dynamics or mouse-usage patterns when working with extremely sensitive information and systems.

Why Is Identity and Access Management Important?

It Eliminates Human Error through Automation and Granular Control

If you run a company or work in the IT department, you know that you have to deal with lots of rules to properly secure access to corporate resources. This means human error should be out of the question. Identity access management helps implement access controls at a granular level through automation of these tasks. Automation also saves you money, effort, and time you usually spend on manually managing all these accesses. This applies to both on-premises and cloud resources.

Improved Business Operational Performance

With IAM put in place, businesses do not need to worry about inefficient overall operational performance, and that it’s because it provides an easier way to implement policies surrounding user privileges, user authentication, and validation, and handling potential issues caused by privilege creep.

Through identity and access management automated workflows are created. So, if there’s a new hire situation or even a role transition happening in your company, IAM makes the process smooth improving also the processing time meant for these kinds of identity changes.

What’s more is that IAM solutions restrict abnormal behavior using technologies like machine learning, artificial intelligence, and risk-based authentication.

It Secures Your Business

Another benefit of identity and access management is that it efficiently secures your business. The granular control I was talking about above also helps significantly decrease the potential data breaches that might be caused by malicious insiders, as IAM works using the principle of least privilege, restricting users’ access only to areas and resources they specifically need for an assigned task. This means that privilege escalation cannot happen without being noticed.

However, not only insider threats are kept away, but also external threats that cannot so easily penetrate your network since so many access controls should be bypassed.

IAM Works to the Benefit of the Users Supporting Productivity

Identity and access management eliminates the headaches that end-users, system admins, or even application owners face when they should sign up or sign in.

For instance, through SSO joined by adaptive MFA, users are provided with more rapid and facile access to resources they need to access, so the overall user experience is definitely enhanced. Besides, through passwordless authentication, users get rid of the hassle of keeping track of the multiple passwords they need along the way.

What’s more is that customers, partners, contractors, and suppliers can access a company’s network through mobile apps, on-premises apps, and SaaS without compromising security thanks to IAM technologies, improving thus the collaboration component.

Helps You Meet Compliance

Identity and access management systems assist businesses in complying with regulatory bodies by allowing them to demonstrate that company data is safe and sound, so thus it is not being exploited. Besides, another advantage would be that if they meet compliance, companies might ensure data availability for audit purposes when necessary.

What are some data protection standards? We can mention a few: GDPR (General Data Protection Regulation) which everybody knows, HIPAA, NIST, the Sarbanes-Oxley Act, and so on. So basically, when audit time knocks on your door you can prove administrative transparency easy and quick, this also being a contributing factor too to the reliability of your business.

IAM Prevents You from Becoming Broke when Talking about Operational Costs

If you use cloud-based IAM services, you can reduce the costs driven by on-premise infrastructure maintenance, thus letting you invest your money more wisely.

Besides, it says no more to password resets. Reportedly, there’s a 50 % that links IT help desk calls to password resets, because, guess why? With so many places to authenticate, people forget their passwords. Not to mention that businesses have to shell out on an average $70 for a password reset. With IAM you rely less on passwords.

Say Goodbye to the Hassle of Weak Passwords

Weak passwords become one of the weakest links and an obvious path for hackers who intend to infiltrate your network and cause data breaches. Through IAM, users will be prevented to use passwords that are not strong enough and will ensure these are changed on a regular basis.

Identity and Access Management Risks

The implementation of identity and access management can face many challenges and here are some:

  • properly providing initial access to a new hire/contractor/service/app;
  • properly reducing or removing access rights;
  • the correct identification of dormant accounts that might pose security risks;
  • another significant problem when adopting an IAM platform is maintaining trust connections after access has been granted;
  • any IAM solution must also work in tandem with the organization’s single sign-on (SSO) strategy. What this means is that the SSO platform should make it simple to gain safe access to a company’s entire app range, whether they’re hosted on-premises or in the cloud.

What Are Some IAM Technologies?

Since IAM systems should have the capacity to integrate with other systems, here are the three main technologies these tools should support:

Security Access Markup Language (SAML)

SAML stands for an open standard that allows an identity provider system, such as an IAM, to exchange authentication and authorization information with a service or application.

OpenID Connect (OIDC)

OIDC makes part also of the category of open standards, which has the capacity to allow users to log into their applications using an identity provider. Even if it shows similarities with the above-mentioned Security Access Markup Language, however, the main difference between them is that the first is based on the OAuth 2.0 standard sending data in JSON rather than XML, as SAML does.

System for Cross-Domain Identity Management (SCIM)

SCIM is the abbreviation for System for Cross-domain Identity Management and represents a standard that allows two systems to automatically share identity information. Despite the fact that both SAML and OIDC can send identity information to an application during the authentication process, SCIM is employed for updated user data maintenance purposes in situations like:

  • a new user is assigned to a service or app;
  • user data modification takes place;
  • process of termination of users is put in place.

Is IAM Only for Employees?

The answer is no. Technology has evolved, which means identities are assigned to much more instances like IoT (Internet of Things) devices as well as to microservices or APIs. This means that companies should implement identity and access management for their business partners, contractors, customers, and remote users as well.

Identity and Access Management Best Practices

Start with an Audit of Existing and Legacy Systems

First and foremost, you should start auditing legacy and existing systems within your company. This step is important for the discovery of different gaps and various opportunities. This also means that you should define what’s the goal of your IAM solution by considering different types of users and accesses.

Consider an RBAC Approach

Another good practice of implementing identity and access management within your system is to consider a role-based access control (RBAC) approach because this strategy works specifically on simplifying access management as accesses are distributed to users in a tight relation with their company’s job role and thus the distribution of access permissions becomes both clear and consistent.

Consider Adaptive-Multi Factor Authentication

SSO combined with adaptive-multi factor authentication makes for a perfect combo that offers admins better control over different permissions. Users are required to use additional factors to authenticate. Based on this, admins have also the possibility to establish conditional access that will check upon user details like network, location, or device. This helps with real-time risk score assignment.

Besides, adaptive MFA eliminates the risk posed by weak passwords since users can authenticate once to all their apps, promoting thus passwordless authentication.

Implement a Lifecycle Management Solution

There’s a continuous workflow within companies because there are new hires, there are employees changing positions or there are employees who resign. This makes the identity access management process complex, thus the necessity for an efficient lifecycle management strategy. How does this approach specifically help companies? It automates admin tasks like employees’ access approval, modification, or revocation of access, thus reducing security risks.

Business Size and Type Should Also Be Considered

Identity and access management can be very useful for medium and small businesses alike as companies have to automatically take care of the management of users’ access to different locations, devices, or computing environments. So basically, it’s important to use IAM to simplify user access providing flexibility in the authentication process.

Integrate Privileged Access Management within your IAM strategy

Data breaches involving compromised credentials have grown in number over time. Just look at the statistics, as, according to, companies pay an average of 4.24 million dollars for a data breach, not to mention that credentials are involved in 61% of all breaches, whether they are acquired via social engineering or hacked via brute force cyberattacks.

Due to the evolution and growth of the “work from home” approach, more and more users are granted privileges because they need different accesses to perform their jobs, so these privileges are no longer limited solely to IT administrators, as anybody can now become a privileged user. That’s why the necessity to integrate an efficient Privileged Access Management approach into an Identity and Access Management Strategy has become more and more self-understood.

Since privileged accounts have special permissions and are the ones close to the most critical data of an organization, they, of course, require special attention and management that only can be acquired through a powerful PAM strategy powered by an automated Privileged Access Management Solution that will properly manage the approval/denial flow to privileged sessions.

A PAM solution will enforce the principle of the least privilege and here’s the benefit of it being integrated with IAM: this ensures that only the appropriate users, who can prove their identities via IAM, have access to the right systems, which are managed by PAM solutions.
