AccessBroker

Summary

AccessBroker is a type of application attack that involves unauthorized intermediaries exploiting access controls to gain illicit entry into systems or data. Attackers leverage vulnerabilities in authentication mechanisms or session management to act as brokers, facilitating unauthorized access or privilege escalation within targeted applications.

Key Characteristics

• Exploitation of weak or misconfigured access control policies within applications.
• Use of intermediary entities or compromised credentials to broker unauthorized access.
• Potential to bypass authentication or authorization mechanisms through session hijacking or token manipulation.
• Often targets web applications, APIs, or cloud services with inadequate identity and access management.
• May involve lateral movement within a network after initial access is brokered.

Defensive Controls

• Implement strong, multi-factor authentication to reduce credential compromise risks.
• Enforce strict access control policies with least privilege principles.
• Regularly audit and monitor access logs for unusual or unauthorized activity.
• Use secure session management techniques, including token expiration and validation.
• Deploy application security testing to identify and remediate access control vulnerabilities.

Related Security Solutions

AccessBroker attacks are mitigated through identity and access management (IAM) solutions, web application firewalls (WAFs), security information and event management (SIEM) systems, and endpoint detection and response (EDR) tools. Additionally, zero trust security frameworks and privileged access management (PAM) solutions play critical roles in preventing unauthorized access broker activities.
