Today’s organizations face the growing challenge of ensuring the security of their information assets in the face of increasingly sophisticated cyber threats. Traditional security models, based on trusting internal users and devices, are becoming insufficient in a rapidly changing IT environment. In response to these challenges, more and more companies are implementing the Zero Trust security model of “never trust, always verify.”
Central to the Zero Trust architecture is identity and access management (IAM), which enables precise control over who, when and how an organization’s resources are accessed. Under this approach, every access attempt is treated as a potential threat and requires multi-step verification, regardless of the location of the user or device.
In this article, we will look at how effective identity and access management is the foundation of a Zero Trust strategy, and discuss the key principles and technologies that support this approach.

Why is the traditional “trust but verify” approach no longer enough, and what is the modern Zero Trust philosophy in the context of IAM?
For decades, cyber security has been dominated by an approach based on building a strong “perimeter” (perimeter security) and assuming that everything inside that perimeter is trustworthy - at least to some degree. The popular slogan “trust but verify” (trust but verify) reflected this philosophy well. We trusted our employees, our internal systems, and verification was often limited to one-time authentication upon entering the network. Unfortunately, this model, while once effective, has simply ceased to suffice in today’s highly complex and dynamic world of digital interactions, where network boundaries are blurring and threats lurk from both outside and within. It has become a relic of the past that puts organizations at increasing risk.
The problem with the “trust but verify” model is that once an attacker manages to penetrate the external line of defense (e.g., through phishing, malware or compromised credentials), they often gain too much access to internal resources. Since he’s already “in,” systems often trust him implicitly, making it easier for him to move around the network (lateral movement), escalate authority and ultimately achieve his goals. It is this inherent trust within the network that is the Achilles’ heel of the traditional approach.
In response to these challenges, the modern Zero Trust (Never Trust, Always Verify) philosophy was born. This is a fundamental paradigm shift that rejects the assumption that there is a “trusted” internal network and an “untrusted” external network. In the Zero Trust model, we don’t trust anyone or anything by default, regardless of whether the user, device or application is inside or outside the traditional network perimeter. Any attempt to access a resource must be treated as if it came from an untrusted source and be subject to strict verification and authorization every time.
In the context of Identity and Access Management (IAM), the Zero Trust philosophy means that:
-
Identity is the new perimeter: Access control is based primarily on strong verification of a user’s (or service/device’s) identity, not just his or her network location.
-
Access is granted on a least privilege basis: Users are granted only the minimum level of access necessary to perform their tasks, and only for as long as necessary (Just-In-Time access).
-
Network microsegmentation: the network is divided into small, isolated segments, and traffic between them is tightly controlled to limit the range of a possible attack.
-
Continuous monitoring and verification: All access attempts and activity are logged and analyzed in real time for anomalies and potential threats. The level of trust in a user or device can be dynamically adjusted based on the user’s behavior.
Implementing Zero Trust is not a one-time project, but an ongoing journey and cultural shift. It requires moving away from outdated assumptions and adopting a much more granular, data- and context-driven approach to security. But in a world where cyber threats are increasingly sophisticated and traditional boundaries are disappearing, Zero Trust is becoming not so much an option as a necessity for any organization that is serious about protecting its digital assets. It is the foundation of a modern, resilient IAM system.

What are the fundamental pillars of a successful IAM system, and why is each equally important to your organization?
An effective Identity and Access Management (IAM) System is much more than a login and password management mechanism. It’s a complex ecosystem of processes, policies and technologies that ensures that the right people (or systems) have the right level of access to the right resources, at the right time and for the right reasons. For such a system to work effectively and realistically protect the organization, it must be based on several fundamental pillars, each of which is equally important and complementary. Neglecting any of these can lead to serious security vulnerabilities.
1 Identity Lifecycle Management: This pillar encompasses all the processes involved in creating, maintaining and deleting digital identities in an organization. It starts from the moment a new employee is hired (onboarding) - creating an account, assigning basic rights, integrating with HR systems. Then, over the course of an employee’s “life” in the company, his or her entitlements may change due to a change in position, promotion or participation in new projects (joiner-mover-leaver - JML - processes). It is crucial that these changes are reflected in IAM systems in a timely and controlled manner, in accordance with the principle of least privilege. Equally important is the efficient and complete removal of access (offboarding) when an employee leaves the company, to prevent the existence of “orphan accounts” that can be an easy target for attackers. JML process automation is key here, especially in large organizations.
2 Authentication: This is the process of verifying that the person or system attempting to gain access is indeed who they say they are. Traditionally, this was based on a login-password pair, but today this is clearly insufficient. Modern authentication must be Multi-Factor Authentication (MFA), requiring the user to provide at least two different types of credentials (e.g., something they know - a password; something they have - a hardware token, an app on their phone; something they are - biometrics). MFA significantly improves security by protecting against the effects of password theft. It is also important to use strong password policies, mechanisms to detect password cracking attempts (brute-force) and, where possible, to move toward passwordless authentication solutions.
3 Authorization (Authorization) and Access Management (Access Management): After successful authentication, the system must decide what resources and activities the identity is authorized to do. That’s what authorization is. The key principle here is the principle of least privilege - granting only the minimum necessary access. Access management mechanisms can be Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC) or policies. It is important that the process of granting, modifying and revoking privileges is formal, documented and subject to regular reviews (access reviews / recertification), especially for privileged accounts.
4 Privileged Access Management (PAM): Privileged accounts (system administrators, service accounts) are the “keys to the kingdom” and compromising them can have disastrous consequences. Therefore, they require special protection. PAM includes specialized tools and processes to securely store privileged credentials (e.g., in “password safes”), rotate passwords, monitor privileged sessions, limit the duration of access (Just-In-Time access), and enforce the principle of least privilege even for administrators.
5 Audit, Monitoring & Reporting: An effective IAM system must provide full visibility into who accessed what, when. This includes detailed logging of all authentication, authorization and privilege change events. These logs must be analyzed regularly (often using SIEM systems) for anomalies, suspicious activity and attempted security breaches. Regular audits of IAM configurations, access reviews, and generation of reports for management and auditors are essential for maintaining compliance and continuous improvement of the system.
These five pillars, working in synergy, form a solid foundation for secure and effective identity and access management in any modern organization.
What are the most common, costly mistakes made in implementing and managing IAM that you must avoid at all costs?
Implementing and maintaining an effective Identity and Access Management (IAM) System is a complex undertaking that, if not done with due diligence and a strategic approach, can become a source of serious security problems and unnecessary costs. There are a number of common mistakes that organizations often make that should be an absolute priority to avoid. Awareness of these pitfalls is the first step to building a truly resilient and effective IAM system.
- Mistake #1: Treating IAM as a one-time technology project rather than an ongoing business program. Many companies approach IAM as if it were the implementation of yet another IT tool - install, configure and “forget it.” Meanwhile, IAM is a living, dynamic process that must constantly adapt to changing business needs, evolving threats and employee turnover. Lack of a long-term strategy, adequate resources for maintenance and continuous improvement, and lack of business commitment is a simple path to failure.
How to avoid? From the beginning, plan IAM as a program, not a project. Provide management support, define clear roles and responsibilities, allocate budget for maintenance and development, regularly review and update policies and processes.
- Mistake #2: Giving excessive authority (the “just in case” rule). This is probably the most common and one of the most dangerous mistakes. In a hurry, out of lack of time for a detailed needs analysis, or simply to “make their lives easier,” administrators often grant users or applications much broader permissions than they actually need. The result? If such an account is compromised, the attacker gains much more room for action.
How to avoid? Rigorously apply the principle of least privilege. Conduct a detailed analysis of access needs for each role and system. Regularly review and remove unnecessary privileges. Use roles and groups instead of assigning permissions directly to users.
- Error #3: Poor management of privileged accounts. Administrator accounts, service accounts, root accounts - these are the “crown jewels” of any infrastructure. Improperly securing them (e.g., shared passwords, no MFA, no activity monitoring) is an invitation to attackers. Compromising a privileged account often means a full takeover of a system or domain.
How to avoid? Implement dedicated PAM (Privileged Access Management) solutions. Use unique, strong passwords for each privileged account, stored in a secure “safe.” Force MFA. Monitor and record all privileged sessions. Use Just-In-Time (JIT) access.
- Error #4: Insufficient or inconsistent use of multi-factor authentication (MFA). MFA is one of the most effective ways today to protect against account takeover due to password theft. However, many organizations implement MFA only for selected systems or user groups, leaving other areas unsecured, or use weak MFA methods (e.g., SMS only).
How to avoid? Strive to implement MFA for all users (internal and external) and all systems, especially critical and publicly accessible ones. Prefer strong MFA methods, such as authentication applications (TOTP) or U2F/FIDO2 dongles, over less secure options (e.g., SMS).
- Mistake #5: Neglecting identity lifecycle management (JML - Joiner, Mover, Leaver) processes. Ineffective onboarding processes for new employees (granting overly broad privileges “at the start”), failure to update privileges when changing positions, and most importantly - incomplete or delayed revocation of access for employees leaving the company (offboarding) leads to the creation of “ghost accounts” and the persistence of unnecessary, risky privileges.
How to avoid? Automate JML processes by integrating your IAM system with your HR system. Implement formal procedures for granting, modifying and revoking access, with appropriate approvals and an audit trail. Conduct regular reviews of active accounts and permissions.
- Error #6: No regular access reviews (Access Reviews / Recertification). Over time, even the best-designed privileges can become outdated or excessive (known as “privilege creep”). The lack of a systematic process for verifying that a user still needs a certain level of access leads to the accumulation of unnecessary risks.
How to avoid? Implement regular (e.g., quarterly, semiannual) access review campaigns in which managers or system owners review and confirm the permissions of their subordinates or application users. Automating this process with Identity Governance and Administration (IGA) tools is highly advisable.
Avoiding these costly mistakes requires strategic planning, the right tools, commitment from the entire organization, and constant vigilance. It’s an investment that pays off many times over in the form of reduced risk and increased resilience to cyber attacks.
How are advanced concepts such as IGA, PAM, CIEM revolutionizing identity management in complex hybrid and multi-cloud environments?
The traditional approach to Identity and Access Management (IAM), while still a cornerstone, often proves inadequate in the face of the increasing complexity of today’s IT environments. We are talking about hybrid architectures, where some resources are on-premises and some are in different public clouds (multi-cloud), dynamically created and deleted resources, a growing number of non-human identities (applications, services, IoT devices), and increasingly sophisticated threats. In response to these challenges, advanced concepts and solution categories have emerged that are revolutionizing the way we think about IAM and manage access.
-
Identity Governance and Administration (IGA) - Identity Orchestration and Compliance. IGA’s solutions go beyond basic provisioning and authentication functions to focus on compliance, risk management and automation of complex identity and access lifecycle processes. Key IGA features include:
-
Managing access requests and approval processes: Automate workflows related to requesting access, its approval by appropriate individuals (e.g., managers, data owners) and granting it.
-
Access Recertification/Attestation: Regular campaigns of review and confirmation of credentials by managers or resource owners, ensuring that access is still needed and complies with the principle of least privilege.
-
Segregation of Duties (SoD): Defining and enforcing SoD policies that prevent users from being given toxic combinations of privileges that could lead to abuse or errors.
-
Role Management and Mining: Advanced tools for defining, analyzing and optimizing roles in RBAC, including role discovery based on analysis of existing privileges.
-
Reporting and analytics: Provide detailed reports for compliance audits and advanced analytics on access risks. The IGA helps organizations answer the questions “who has access to what?” and “is this access appropriate and consistent with policies?”.
-
Privileged Access Management (PAM) - Kingdom Key Protection. As already mentioned, privileged accounts are the number one target for attackers. PAM’s solutions focus on their special protection by:
-
Secure credential storage (Password Vaulting): A central, encrypted repository for privileged account SSH passwords and keys, eliminating the need to store them in less secure locations.
-
Automatic password rotation: Regular, automatic password changes for privileged accounts, minimizing the risks associated with password leaks or prolonged use.
-
Privileged Session Management: Real-time logging (recording) and monitoring of administrator sessions, and the ability to interrupt them in a controlled manner in case of suspicious activity.
-
Just-In-Time (JIT) and Just-Enough-Access (JEA) access: Granting privileged access only for a specific period of time, necessary to perform a specific task, and only to the minimum extent required.
-
Delegate privileges without revealing passwords: Enable administrators to perform tasks without direct access to root/administrator account passwords. PAM is absolutely key to preventing escalation of powers and limiting damage in case of compromise.
-
Cloud Infrastructure Entitlement Management (CIEM) - Cloud Entitlement Management. In cloud environments (AWS, Azure, GCP), entitlement management becomes extremely complicated due to the multiplicity of services, the granularity of IAM policies and the dynamic nature of resources. CIEM’s solutions specialize in providing visibility, analytics and privilege optimization in the cloud:
-
Entitlement discovery and visualization: Identify all identities (human and non-human) and their effective permissions to individual cloud resources, often in the form of a graphical map.
-
Privilege risk analysis: Detecting excessive privileges (over-permissioning), unused privileges, risky configurations (e.g., publicly available roles with escalation) and potential attack paths.
-
Recommendations on the principle of least privilege: Suggest optimal IAM policies that minimize risk without limiting necessary functionality.
-
Continuous monitoring and detection of configuration drift: Alerting on unauthorized changes in permissions or the emergence of new risks. CIEM is essential for maintaining control over the growing and complex ecosystem of entitlements in public clouds.
These advanced concepts and tools do not replace the core pillars of IAM, but expand and strengthen them, allowing organizations to more effectively manage risk in an increasingly complex and dynamic world of digital identities and access.
What future trends and technologies in the IAM field (e.g., biometrics, AI, decentralization of identity) will change the way we protect access to resources?
The Identity and Access Management (IAM) area is one of the fastest growing segments of cyber security. New trends and technologies are constantly emerging that have the potential to revolutionize the way we authenticate users, manage permissions and protect access to our valuable resources. Watching for these changes and preparing for their arrival is key to maintaining a successful IAM strategy in the future.
1 Passwordless Authentication and Biometrics: Passwords, despite many attempts to strengthen them, still remain one of the weakest links in the security chain. They are difficult to remember (especially when they have to be unique and complex), susceptible to phishing, theft or brute force cracking. That’s why there is an increasing emphasis on password-free solutions that rely on other methods of identity verification.
-
Biometrics: Fingerprint scanners, facial recognition (e.g., Windows Hello, Face ID), iris scanning or voice analysis are becoming more common and integrated into devices and applications. They offer a high level of safety and convenience for the user. However, the challenge remains in protecting the biometric data itself and ensuring reliability under various conditions.
-
FIDO2/WebAuthn security keys: Hardware keys (e.g., YubiKey) or built-in mechanisms (e.g., Windows Hello) compliant with the FIDO2 standard enable strong, cryptographic authentication without the need to enter a password, often in combination with PIN or biometrics. This is one of the safest solutions currently available.
-
Authentication apps and push notifications: one-click authentication in a push notification on a trusted mobile device or through app-generated codes (TOTP) are also gaining popularity as an alternative or supplement to passwords.
2 Artificial intelligence (AI) and machine learning (ML) in IAM: AI and ML have great potential to improve many aspects of IAM:
-
Adaptive/Contextual Authentication: AI-based systems can analyze hundreds of signals (e.g., user location, device type, time of day, typical behavior, IP address reputation) in real time to dynamically assess the risk of a given login attempt. Depending on the level of risk, the system may require additional verification steps (step-up authentication) or block access.
-
User and Entity Behavior Analytics (UEBA): AI can learn typical user and system behavior patterns and then detect anomalies that may indicate a compromised account, insider threat or ongoing attack.
-
IGA process automation: AI can support processes such as role discovery, recommending permissions or identifying risky access combinations.
3 Decentralization of Identity (Decentralized Identity) and Self-Sovereign Identity (SSI): Today, most of our digital identities are controlled by centralized providers (e.g. Google, Facebook, employers). The decentralized identity model, often based on blockchain or Distributed Ledger Technology (DLT), seeks to give users full control over their own identity data and credentials. In the SSI model, users store their verified attributes (e.g., college diploma, driver’s license) in a digital wallet on their device and can selectively share them with third parties without going through a central authority. This approach has the potential to revolutionize privacy, security and the way we prove our identities online.
4 Identity Management for Devices and Services (Machine Identities): With the growth of IoT, microservices and automation, the number of non-human identities (machines, apps, APIs, containers) is growing rapidly and often surpasses the number of human identities. Effective lifecycle management of these machine identities, their authentication and authorization (e.g., using certificates, tokens, API keys) is becoming a critical challenge for IAM systems.
5 Convergence of IAM and other security areas: We are seeing increasing integration and convergence of IAM systems with other security solutions, such as Zero Trust Network Access (ZTNA) systems, Cloud Access Security Brokers (CASB), Security Service Edge (SSE) or XDR (Extended Detection and Response) platforms. Identity is becoming the focal point for many security decisions, and data from IAM systems is being used to enrich context and automate responses across the security ecosystem.
These trends indicate that the future of IAM will be based on even greater automation, intelligence, granularity and adaptability, while striving to improve the user experience and strengthen their control over their own identity. What this means for organizations is that they need to stay abreast of these changes and be ready to adapt their IAM strategies and tools.
