SaaS applications have a mind of their own - Do you understand the risk associated with multi-cloud solutions?

Multi-cloud environments are common and popular because they simplify what used to be complicated workflows, and they help organizations stay connected in an efficient manner. They do, however, also pose a significant cybersecurity challenge because they allow users to play multiple roles and have numerous constantly changing privileges.

This is simply how modern corporation’s work. The challenge quickly becomes how do you keep track of all the users and their constantly changing privileges. CISOs are tearing their hair out because they know they need to give proper access to their teams, while also having the capability to provide reporting to executive boards regarding employee access profiles, activities and privileges. Unfortunately, the current systems do not equip the practitioners with compliance reports across environments, systems, applications, and all personas of users.

Current identity and access management solutions often fail to recognize users' activities and privileges across multiple cloud environments, making clean decommissioning difficult and leaving traces of potential vulnerabilities.

SaaS Applications Have a Mind of Their Own
The maturity of the SaaS applications runs the gamut, and not all provide native integration into the centralized IAM solutions. Current IAM/PAM and SIEM solutions often focus on single-user activities and struggle to manage the scale and complexity of changing privileges and access requests.

Organizations simply must leverage customers’ existing investments into the SaaS applications rather than create a parallel directory and access management infrastructure just for those new SaaS applications.

Remote Workforce is Here to Stay
The pandemic brought us the remote workforce, and it is here to stay. This development has refocused the need for supporting the remote workforce without compromising security – a considerable challenge from a user access perspective. Remote access adds another layer of complexity to privileged access management by increasing the number of vulnerability points, and available software solutions are unequipped to effectively manage the lineage of the users and remediate unauthorized access problems in real-time.

Why Organizations Should Care about Privilege Abuse
Inside-Out Defense has observed diverse consequences from the above challenges in our engagements spanning several industries. Though the use cases have varied, these are some of the common patterns of privilege access abuse:

  • Users launching privilege escalation.
  • Lateral movements.
  • Privilege persists launched through 3rd party accounts over compromised zombie user accounts to orchestrate data exfiltration.
  • IP counterfeiting.
  • HIPAA compliance abuse and undue access to patient diagnostic data.
  • PoS systems DDoS.
  • Malicious third-party access.
  • Unmanaged systems orchestrating attacks at scale.

In a nutshell, IAM/PAM and SIEM solutions, as we know them, are being outsmarted by faster threats and more determined threat actors. Legacy vendors mainly focus on single-user activities to determine potential red flags and aggregate them for further processing without considering the individual user's overall context and activities across the environments.

Secondly, they usually integrate with a workflow system, generating a backlog of access requests that cannot scale with increased user activities. Users' privileges constantly change; they usually do not and shouldn’t persist. Enterprises direly need to address these challenges by providing a privilege abuse defense at the “time of use” by continuously detecting privilege abuse behaviors in real-time and remediating abuses in line.
