What are the most effective IAM policies and standards for preventing insider threats?

由人工智能和领英社区提供技术支持

Insider threats are one of the most challenging and costly risks for any organization that handles sensitive data or assets. Whether malicious or accidental, insiders can compromise the security, reputation, and compliance of the business. To prevent or mitigate insider threats, you need to implement effective identity and access management (IAM) policies and standards that govern who can access what, when, and how. In this article, we will discuss some of the most effective IAM policies and standards for preventing insider threats, and how to apply them in your organization.

1 Role-based access control

Role-based access control (RBAC) is a common and simple way to assign access rights to users based on their roles and responsibilities within the organization. RBAC helps to enforce the principle of least privilege, which means that users only have the minimum access required to perform their tasks. RBAC also helps to reduce the complexity and maintenance of managing access rights, as you can group users into roles and assign permissions to roles instead of individual users. RBAC can be implemented using tools such as Active Directory, LDAP, or IAM platforms.

RBAC is a method of defining and managing access controls in which permissions are associated with specific roles within an organization. However, it has limitations that make it less suitable for today's complex and dynamic business environments such as: Role-based access is rigid and may not adequately address the unique access requirements of individuals or specific situations. RBAC struggles to meet stringent regulatory requirements as it doesn't provide the level of control and auditability necessary for compliance. As organizations grow and diversify, managing access controls through roles becomes increasingly complex. Entitlement creep - users accumulate access rights they shouldn't have, creating security vulnerabilities.

2 Segregation of duties

Segregation of duties (SoD) is a complementary policy to RBAC that aims to prevent conflicts of interest, fraud, or errors by ensuring that no single user can perform or approve critical or sensitive tasks. SoD requires that different users or roles are responsible for different stages or aspects of a process, such as creating, reviewing, approving, and auditing. SoD can be enforced using workflows, approvals, or audits that require multiple sign-offs or validations from different users or roles. SoD can also be implemented using tools such as IAM platforms, business process management software, or blockchain technology.

Segregation of Duties is a control used to prevent financial misstatement risks, fraud, theft, and misuse of data by dividing a process into separate tasks so a single user doesn't have control over an entire process. SoD presents significant challenges for almost every company, regardless of size. Verifying SoD violations involves digging through dozens of screens in your ERP for hundreds of users to investigate potentially conflicting job responsibilities. Evaluating thousands of complex security and configuration settings through manual research on error-prone spreadsheets is inefficient. And in business, where time is money, these mistakes can easily cost your company millions.

3 Multi-factor authentication

Multi-factor authentication (MFA) is a security measure that requires users to provide more than one piece of evidence to verify their identity before accessing a system or resource. MFA typically combines something the user knows (such as a password), something the user has (such as a token or a device), and something the user is (such as a fingerprint or a face scan). MFA helps to prevent unauthorized access by insiders who may have stolen or guessed someone else's credentials, or by outsiders who may have compromised the network. MFA can be implemented using tools such as IAM platforms, authentication apps, or biometric devices.

La autenticación multifactor (MFA) refuerza la seguridad al requerir múltiples pruebas (contrase?a, posesión de dispositivo, características personales). Previene accesos no autorizados por robo de credenciales y se implementa con herramientas como IAM o aplicaciones de autenticación.

En el escenario actual de ciberseguridad, la Autenticación Multifactor (MFA o AMF) se erige como una barrera formidable para contener las técnicas de ataque de viaje imposible. La implementación de una herramienta robusta de Identidad y Acceso (IAM) desempe?a un papel crucial en este control, especialmente cuando se utiliza un enfoque basado en tokens vinculados a dispositivos. Este enfoque no solo a?ade capas adicionales de seguridad, sino que redefine la experiencia de autenticación, brindando una defensa sólida contra amenazas sofisticadas

4 Logging and monitoring

Logging and monitoring are essential policies and standards for detecting and responding to insider threats. Logging involves collecting and storing data about user activities, such as login attempts, access requests, file transfers, or changes made to systems or resources. Monitoring involves analyzing and alerting on the logged data to identify any anomalies, deviations, or violations of policies or standards. Logging and monitoring help to deter insiders from abusing their access rights, as well as to provide evidence and accountability in case of an incident. Logging and monitoring can be implemented using tools such as SIEM, log management, or user behavior analytics software.

Conduct regular access reviews and audits to ensure that users only have access to resources they need. This helps identify and revoke unnecessary permissions promptly.

La convergencia de todos los vectores hacia un sistema SOAR (Orquestador) no es solo una integración, es una puerta hacia un monitoreo inteligente y controles abarcadores de eventos. Este enfoque holístico no solo asegura la detección proactiva, sino que también proporciona una visión completa del estado de salud de los activos. En un panorama donde la inteligencia y la acción coordinada son esenciales, la implementación de un sistema SOAR se convierte en la piedra angular de una defensa robusta

5 Training and awareness

Training and awareness are not technical policies or standards, but they are equally important for preventing insider threats. Training and awareness involve educating and informing users about the security risks, policies, standards, and best practices that apply to their roles and access rights. Training and awareness also involve fostering a culture of security and trust within the organization, where users are encouraged to report any suspicious or abnormal activities, and where whistleblowers are protected and rewarded. Training and awareness can be implemented using tools such as e-learning, newsletters, posters, or gamification.

An effective insider threat mitigation strategy is the implementation of policy-based access controls. Having solid, well-defined policies and knowing which access privileges each role requires. As organizations grow and evolve, the right access governance solution can allow for more efficient changes and decrease risk by focusing on policies and assignments rather than roles.

Another aspect not mentioned is Least Privilege Principle: Enforce the principle of least privilege, ensuring that users have the minimum level of access necessary to perform their job functions. Regularly review and update permissions based on job roles.
