Identity and Access Management (IAM) involves creating a digital identity for each user and device in a network. This digital identity governs how users interact with software suites and hardware devices.
This helps ensure only the right people have access to computers, software apps, and any IT resources. It also mitigates insider threats – among the leading causes of data breaches.

Security
Identity and access management (IAM) is a cybersecurity discipline that ensures that only the right people get into networked systems, hardware, software apps, and data sources. This means that each person must have a digital identity, which needs to be authenticated before any access can occur. This is often done with multiple forms of authentication, and it must be performed at the individual user or device level.
Once an identity has been authenticated, IAM systems determine which IT resources the individual or machine should be allowed to use. This is the second key component of IAM and typically involves granting access to applications, networks, and servers according to the organization’sorganization’s established rules, policies, and privilege levels. Access must also be managed over time, with new users getting onboard and old ones being deprovisioned.
Finally, identity and access management (IAM) also have to perform an audit function to monitor and record activities like when users log in and out of systems, what they are doing, and whether any suspicious behavior is present. This helps support security and compliance by giving teams the necessary visibility and intelligence to take action when problems arise. For example, a system that records the number of times a username and password have been reused can alert administrators to a potential breach and trigger an automated lockout.
Access
The techniques, guidelines, and instruments that control how users, gadgets, software programs, and IT systems can access are called identity and access management (IAM). Its core premise is one digital identity for each person or thing so that any login attempt matches up to a database of people and their associated roles and access privileges in the company network. Such databases contain employee names, job titles, managers, direct reports, mobile phone numbers, and a list of the IT assets each person is allowed to use, including computers, hardware, and software apps.
Authenticating these identities is typically done via a verification process that requires something the user knows (like a password), something they have (like a security token or smartphone software app), or something that’s part of them (like fingerprints, facial or voice recognition). IAM also handles provisioning and creating new identities and their access privileges in a company’s-company’s IAM system. Often this is done via role-based access control (RBAC), so each person is granted specific access to the systems they need to do their jobs.
Privileged access management is another aspect of IAM that protects businesses from cyber and insider attacks by ensuring higher permission levels are only given to those who need them to do their jobs. This is accomplished by using IAM solutions to verify users’ identities with factors like their current device, IP address, and location before granting them access to sensitive applications or data.
Compliance
Cybersecurity incidents and stringent compliance regulations drive the growth of the identity and access management market. The rise of small and medium-sized enterprises also boosts the demand for IAM solutions to prevent cyberattacks and identify frauds. The market is expected to grow further by adopting IAM solutions, healthcare and life sciences, IT & telecom, retail and consumer packed goods, and government.
IAM systems are designed to perform three essential tasks: verify identities, authenticate access requests, and govern identity. This allows the correct individuals access to computers, hardware, software apps, data, and other IT resources. This is a complex task since new users are constantly coming in and others are leaving, and the list of privileges needs to be continuously updated.
IAM can help automate many of these processes so the IT department doesn’tdoesn’t have to update permissions for hundreds or thousands of employees constantly manually. It can also help reduce the risk of a breach by ensuring that only people with the proper credentials can access the system. In addition, it can help a company meet regulatory compliances by ensuring that the appropriate data is accessed only by authorized individuals. This can be done by providing that only authenticated identities can log in and limiting the resources they can access at any time.
Governance
With hybrid working becoming increasingly common, employees need secure access to corporate systems, whether at the office or at home. IAM helps make this possible by verifying a person’sperson’s identity before granting access to the company’s-company’s databases, data, and applications. IAM also ensures that the correct people get access to suitable devices and apps.
A crucial part of IAM is ensuring that when employees leave the business, their access privileges are de-provisioned quickly. If this doesn’tdoesn’t happen, it leaves a security gap for hackers to exploit. IAM solutions can automate this process and help prevent security breaches by enforcing granular policies and identifying potential phishing campaigns.
IAM also manages the digital identities of people, devices, and hardware applications. This enables businesses to authenticate at multiple tiers, including a central service, and then again locally for specific applications.
IAM can help organizations to embrace a zero-trust policy, which moves away from the traditional idea of trusting everyone and everything that connects to a network. A zero-trust approach ensures that IAM constantly monitors and assesses each user’suser’s attributes based on existing policies to decide if they are authorized to access a given resource. This enables businesses to be more agile and responsive to cyber attacks. This is particularly important for critical sectors like water, power, digital infrastructure, and healthcare.
