Enterprises run smoothly only when the right resources are accessed by the right people at the right time. However, when it comes to brass tacks, that’s harder than it sounds.
Today, work teams are not only larger but also more distributed, relying on software tools more than ever, which makes controlling and tracking user access all the more complex. When access is mismanaged or managed poorly, not only do teams lose clarity of who can use what data and which systems, but also the propensity for mistakes increases and productivity slows down.
Add to that the exponential increase in cyberthreats, and enterprises are scrambling to rethink where their greatest vulnerabilities lie. That’s where IAM (Identity and Access Management) comes in. Basically, this framework of technologies, processes, and policies assist and enable enterprises to control user access to critical corporate data and manage digital identities.
In today’s day and age of AI (artificial intelligence), compromised user credentials might just be the commonest target for attackers to gain access into enterprise networks through ransomware, phishing, and malware attacks. That’s what makes IAM so critical as it helps safeguard valuable resources by preventing breaches and control access. This guide delves into what IAM is, why it’s so important, and what enterprises need to consider when choosing IAM solutions.
All About IAM: How Does It Work?
IAM is a framework or approach that outlines and defines how organisations control who exactly can access their data, workloads, intellectual property, applications, and systems. It essentially defines the who, why, where, when, what, and how of resource access in an enterprise, allowing the right people to have controlled access to the corporate resources they require to get their work done.
More importantly, “users” in IAM represent digital identities, which include not only humans such as team members, employees, or customers, but also non-human entities such as robotics, IoT devices, or software.
IAM starts with authentication, matching applications, devices, and users to credentials to verify their legitimacy and thus allowing only devices and users that are allowed to gain access can do so. When it comes to authorisation, IAM determines what every system/user is allowed to access and do after they’re granted access, which means no one can take action they have no right to take.
Furthermore, IAM manages the entire identity spectrum, including onboarding, any role changes, and deprovisioning, keeping access up-to-date and preventing cybersecurity and IT teams being burdened with manual provisioning and deprovisioning. Next, it monitors and tracks activity to spot potential security issues or unusual behaviour, ending the process with auditing user access changes and overall activity, providing clarity for accountability, compliance, and investigations.
So, how does IAM work? It basically authenticates devices and users using the above process – by verifying credentials against defined access and identity permissions stored in a secure database. Once they’re authenticated, it assigns specific access levels based on user roles as opposed to complete system access, thus protecting sensitive data and preventing unauthorised actions.
Why Has IAM Become Critical?
When we speak of external threats, we’re usually referring to traditional perimeter-based security – where everything within the confines of the corporate firewall was considered to be “trusted.” However, that setup no longer reflects how enterprises operate today, as identity is now the new perimeter; whether machine or human, identity enables access to systems and data.
With enterprises increasingly having turned to SaaS applications, hybrid working setups, and cloud services, security has shifted towards Zero Trust principles: always assume breach, grant least-privilege access, and verify explicitly.
Rather than simply trying to break through these perimeter defences, attackers have adapted to the changing AI environment and are increasingly targeting identities through stolen credentials, social engineering, and phishing attacks. In a majority of the cases, it’s no longer even “hacking,” but rather simply logging in using legitimate credentials. That’s what’s made protecting access and identity one of the most critical priorities for enterprises today.
The Future Of Identity: Constant Vigilance
With the advent of AI, the cybersecurity threat landscape and attack vectors have become ubiquitous and omnipresent. Modern identity-driven hacks, more often than not, bypass the traditional cyber-threat chain by accomplishing lateral movements by directly leveraging compromised credentials, thus launching bigger and more devastating attacks. That, along with the rapid expansion of the digital workforce, underscores the need for enterprises to activate a strong and flexible identity security solution even more, and that should include IAM.
IAM augments user experience and security by assigning only specific roles to users and making sure that only the right and required digital identities possess the right level of access to business networks and resources. This not only ensures security, but also paves the way for better business outcomes and the viability of cloud adoption and remote working setups. And when these two solutions are implemented together, they can possibly stop malicious attackers and adversaries that might manage to circumvent other security measures, such as EDR (endpoint detection and response) tools.
