User Access Management Basics

User access management controls user permissions and privileges that grant or deny access to digital tools and online resources within a system or organization.

What is user access management?

UAM is a component of Identity and Access Management (IAM) and is essential to modern IT infrastructure. Once a user’s Identity is verified through authentication, UAM systems administer access to the right tools at the right time based on pre-determined factors for individuals or groups. For businesses, this usually includes controls around access to internal or external applications, user permissions, and security requirements.

In the analog world, you could compare the function of user access management to that of security at a university. Just as security staff check IDs at the entrance to verify a person’s Identity, their roles — such as student, professor, or administrative professional — determine what resources and areas they can access on campus and when they can access them. For example, a faculty lounge would not allow student access and may be off-limits to anyone but building management professionals on weekends. UAM ensures that only authorized users can access necessary resources, and only as needed.

Today, challenges can arise as companies grow, and employees with varying roles and responsibilities increasingly use external enterprise solutions to do their jobs. An IAM solution helps govern this by seamlessly managing user identities and access all in one place.

Boosting efficiency and security with UAM

User access control ensures organizational security and efficiency by granting appropriate access levels based on users' roles and responsibilities. This minimizes the danger of unauthorized access or data breaches while streamlining user onboarding, offboarding, and permissions management processes for smoother operations.

By enforcing a standard operating procedure (SOP) for user access management, organizations can strengthen their security posture and improve operational performance while maintaining privacy, integrity, and availability of critical assets.

Through UAM, IT teams can:

• Control access: Administrators can grant, modify, and revoke user access based on roles, responsibilities, reducing the risk of unauthorized access.
• Enable Single Sign-On (SSO): Include SSO capabilities to allow users to access numerous applications with one set of credentials, improving user experience (UX) and productivity while reducing password fatigue.
• Enforce least privilege: Ensure users have the minimum permissions necessary to perform their job functions to reduce potential security breaches or insider threats.
• Enhance compliance: Readily comply with industry regulations and standards, such as HIPAA, SOC2, GDPR, and PCI-DSS, which require strict control over data access.
• Facilitate auditing and reporting: Generate detailed logs and reports with a user access management audit on user access activities, enabling organizations to detect and investigate security incidents, monitor user behavior, and demonstrate compliance during audits.
• Streamline provisioning and deprovisioning: Automate the creation, modification, and revoking of user accounts to reduce administrative overhead and ensure timely, accurate access changes.
• Support scalability and flexibility: Manage increasingly complex user access requirements across applications, systems, and platforms.

UAM and Zero Trust

All digital enterprises need to secure their networks and data from increasingly sophisticated cyberthreats. Traditional perimeter-based security models have become outdated as remote work, cloud adoption, and advanced hacking techniques increase. Zero Trust provides a comprehensive security approach for safeguarding data and resources in user access workflows.

The Zero Trust Security Model:

• Zero Trust is a security architecture that assumes no user, device, or network is trusted by default, whether inside or outside the organization's network perimeter.
• The main principle of Zero Trust is "never trust, always verify,” which means authenticating, authorizing, and continuously monitoring every access request.
• This approach uses multiple layers of security controls, such as Multi-Factor Authentication (MFA), encryption, micro-segmentation, and real-time monitoring, to prevent unauthorized access and data breaches.
• Key components include IAM, device management, network segmentation, application security, and data protection.

How Zero Trust enhances user access management

Organizations can bolster their security posture by integrating Zero Trust principles with various types of access control by implementing these essential practices:

• Continuously authenticate and authorize: Require ongoing verification throughout user sessions rather than relying solely on initial login credentials.
• Engage granular access controls: Activate controls based on user Identity, device health, location, and other contextual factors.
• Integrate with UAM solutions: Use SSO, MFA, and user entity behavior analytics (UEBA) to streamline access management and strengthen security across all resources and environments.
• Leverage a comprehensive framework: Execute a consistent and scalable approach to secure access to applications, data, and infrastructure, regardless of user location or device.
• Enact a risk-based access management approach: Assess and adapt security policies based on real-time threat intelligence and user behavior data.
• Enable secure remote work : Safeguard access to resources to support productivity and collaboration.

Identifying and protecting high-value data

Methods to classify critical assets:

• Data classification and inventory: Catalog and categorize data based on its sensitivity, confidentiality, and importance to the organization.
• Access log analysis: Review user access logs to determine which data is most frequently accessed and by whom.
• Business impact analysis: Evaluate the possible consequences of data loss, theft, or unauthorized access on the organization's operations, reputation, and financial stability.
• Stakeholder interviews: Interview key stakeholders, including executives, department heads, and IT staff.
• Regulatory compliance requirements review: Identify data subject to industry-specific regulations, such as HIPAA, FedRAMP, PCI-DSS, or GDPR, which may require additional protection.
• Security assessments: Perform vulnerability scans, penetration tests, and risk assessments to identify high-value data at risk of exposure or compromise.
• Threat modeling: Interpret potential threats and attack vectors to determine which data assets will most likely be targeted by malicious actors.
• Criticality assessments: Evaluate the importance of each data asset to the organization's core functions and prioritize protection efforts accordingly.

Implementing access controls to protect sensitive information

IT and security teams can ensure that only authorized users access sensitive data by combining data protection methods and enacting tight controls.

Strategies that enhance security include:

• encrypting data in transit and at rest
• segmenting networks to isolate critical systems
• continuously monitoring for suspicious activity
• providing employee training on security best practices

The crucial role of strong password policies and MFA

Best practices for enforcing strong password policies

Effective user access management unifies systems to address the challenges of fragmented Identity stores, siloed security tools, and an over-reliance on passwords. According to Gartner , while strong password policies are still necessary, they cannot mitigate all password-related threats. IAM best practices involve streamlining the process of password policy creation, review, and revision. Password policies should be practical to implement and meet applicable regulatory and audit requirements without disrupting UX.

Beyond solid password policies, IT and security teams must tackle issues like standing privileged credentials, orphaned or overprivileged accounts, and manual configuration errors that can leave organizations vulnerable to Identity-related attacks and audit failures. Consolidating Identity management systems and implementing centralized access controls can provide greater visibility and control over who has access to sensitive data and systems.

While passwords are still common in Customer Identity use cases, the push to Passkeys has helped strengthen security. Passkeys deliver a simpler and more secure alternative to traditional passwords for signing into consumer apps and websites. By using biometric data or device PINs, passkeys provide a seamless UX while reducing the risk of online attacks like phishing. However, they are not a best practice for workforce security.

How MFA strengthens user access security

MFA adds a level of protection beyond passwords, enhancing user access security. It grants access only after users provide two or more forms of identification, often combining something they know (like a password) with something they have (like a smartphone) or something they are (like a fingerprint). MFA can minimize the likelihood of unauthorized access even when a user's password has been exposed or stolen.

MFA can be implemented using various methods:

• SMS or voice-based one-time passwords (OTP)
• Mobile app push notifications
• Hardware or software-based tokens
• Biometric authentication (fingerprints, facial recognition, etc.)

• Enforce MFA for all user logins to significantly improve security posture, protect sensitive data, and comply with industry regulations and standards.
• Prioritize MFA for privileged accounts, remote access, and cloud-based applications.
• Combine MFA with strong password policies and centralized Identity management for a comprehensive security framework that safeguards against Identity-related threats and data breaches.

Phishing-resistant MFA in user access management

With the increasing complexity and sophistication of cyberthreats, conventional MFA methods, such as SMS or one-time passwords (OTP), have become susceptible to highly targeted and elaborate phishing attempts. These attacks can devastate organizations with lost productivity, bad publicity, penalties, legal costs, ransom demands, loss of consumer trust, and erosion of brand value.

Organizations should invest in phishing-resistant MFA solutions that enhance security without compromising UX and employ authenticators that are resistant to social engineering, including:

• Passwordless authentication using biometrics
• Mobile app-based authentication with secure encryption and device binding
• Hardware security keys (e.g., YubiKey)
• Common Access Cards (CAC) or Personal Identity Verification (PIV) cards

By implementing phishing-resistant MFA, organizations can:

• Protect against phishing attempts in real-time with support for a range of phishing-resistant authenticators, including passwordless options
• Detect suspicious activity and evaluate device security posture
• Respond with alerts and insights to take action against suspicious activities
• Reduce the risk of account takeovers, data breaches, and other Identity-related attacks

Automating user access management workflows

Automated UAM workflows increase efficiency, reduce human error, and improve security by streamlining processes and minimizing manual intervention.

Examples of automated workflows:

• Onboarding and offboarding: Provision and deprovision user accounts based on integrated HR system data in real-time.
• Role-based access control (RBAC): Assign access rights based on predefined roles and responsibilities.
• Access review and recertification: Periodically review user access rights to ensure appropriateness and compliance with security policies and regulatory requirements.
• Self-service access requests: Enable users to request resource access to reduce IT staff workload and improve UX.

Least privilege and just-in-time (JIT) access

The principle of least privilege (POLP) reduces security risks associated with excessive or unnecessary access rights. By granting users only the minimum access required to perform their jobs, organizations can mitigate the potential impact of compromised accounts, insider threats, and data breaches.

JIT extends the concept of least privilege by adding predetermined time limits to resource access. These controls include:

• Temporary access provisioning: Automatically grants access to resources for a limited time based on specific tasks or projects
• Dynamic access control: Adjusts access rights in real-time based on contextual elements, including user location, device security posture, and risk score
• Workflow-based access requests: Integrates access requests into existing workflows, such as change management or incident response processes
• Continuous monitoring and auditing: Reviews and audits user access to detect and remediate anomalies and ensure compliance

Leveraging role-based and attribute-based access control

RBAC assigns access rights based on predefined roles and responsibilities so that users can access resources necessary for their job functions. Attribute-based access control (ABAC) grants access based on user attributes, resource attributes, and environmental conditions, enabling fine-grained access control decisions. A hybrid approach creates a more flexible, scalable, and dynamic access management system. Combining RBAC and ABAC makes it easier for IT teams to manage access policies across large and complex organizations and reduces administrative overhead.

Methods to automate user access provisioning and deprovisioning:

• Automated role assignment: Assigns users to predefined roles based on their job function, department, or other relevant attributes, reducing manual effort and ensuring consistency.
• Attribute-based provisioning: Grants or revokes access to resources based on user attributes and predefined policies, keeping access aligned with current user characteristics and requirements.
• Deprovisioning triggered by events: Removes access rights when users change roles, leave the organization, or no longer require access, ensuring compliance with security policies.
• Integration with Identity management systems: Seamlessly integrates access automation with existing identity management solutions, including HR systems or directories.

Auditing for compliance and security

Regular audits ensure ongoing UAM security and compliance with internal policies and external regulations.

Strategies for effective auditing and log management:

• Centralized log management: Consolidate logs into a central repository for more accessible analysis and correlation.
• Real-time monitoring and alerts: Implement real-time monitoring systems to detect and react quickly to security events.
• Log retention policies: Establish clear guidelines for log retention periods to meet compliance requirements and support forensic investigations.
• Regular audit trails review: Conduct periodic reviews of audit trails to identify anomalies, unauthorized access attempts, and potential security breaches.
• Security information and event management (SIEM): Integrate log management with SIEM systems for advanced threat detection and incident response.
• Automated log analysis: Leverage machine learning (ML) and artificial intelligence (AI)-powered tools to automate log analysis and identify patterns and anomalies that could indicate security risks.
• Access controls and encryption for log data: Implementing stringent access controls and encryption mechanisms to protect sensitive log data from unauthorized access or tampering.
• Compliance checks and reporting: Assess compliance against relevant regulations and generate reports demonstrating adherence to security and privacy requirements.

To overcome these challenges, organizations can adopt strategies, including:

• Compatibility testing
• Phased integration approaches
• Robust data validation and error handling
• Consistent security policies
• Scalable architecture across on-prem and cloud applications (private or public cloud)

How IT teams can leverage API integrations

Seamless security workflows:

• Standardize RESTful APIs: Use well-documented and standardized RESTful APIs for easy integration with existing systems and applications.
• Secure API authentication with OAuth: Adopt OAuth to ensure secure authentication and authorization when accessing UAM functionalities through APIs.
• System for cross-domain Identity management (SCIM): Employ SCIM to streamline user and group management across different systems and platforms.
• Centralize security policies with API gateways: Implement API gateways to enforce centralized security policies, rate limiting, and access control for all API interactions.
• Webhook notifications for real-time updates: Enable notifications for real-time updates and synchronization between UAM and other systems to ensure data consistency and timely access provisioning.

Supporting a distributed workforce

Modern organizations must secure their workforce regardless of location. IT teams are now responsible for supporting all devices while enforcing consistent, comprehensive, and compliant security access controls at scale. For operational efficiency, integrated user access management solutions that don’t involve multiple vendors and platforms are essential.

How UAM streamlines device security:

• Comprehensive device support: Manages access across all devices, including desktops, laptops, smartphones, and tablets.
• Consistent security policies: Enforces uniform security policies and access controls across all managed (corporate-owned) and unmanaged devices.
• Frictionless UX: Provides a seamless and user-friendly access experience across devices.
• Suspicious activity detection: Implements mechanisms to determine questionable activity, like unusual login attempts or unauthorized access.
• Device security posture evaluation: Actively assesses device security and grants access to resources only when it ensures the device meets the required security standards.

Future trends in user access management

As technology evolves, organizations must anticipate the impact of emerging technologies on UAM and proactively adjust their strategies to maximize security and improve UX. Growing trends include:

• AI and ML: Automated access decisions, detecting anomalies, and improving policies based on user behavior and risk profiles
