Healthcare organizations are prime targets for ransomware attacks1, placing sensitive patient data and critical systems at risk. Alarmingly, ransomware doesn’t always strike directly—it often infiltrates through third-party providers. A notable example is the attack on Change Healthcare, which disrupted services across its network and significantly impacted downstream providers. These incidents underscore the need for stringent third-party access controls, a key component of an effective Identity Governance and Administration (IGA) framework.
IGA not only helps secure access for employees but also enforces controls for external stakeholders, mitigating the risks posed by indirect attacks. By managing identities and access permissions comprehensively, IGA minimizes vulnerabilities and strengthens defenses against ransomware. Here’s how this critical framework safeguards healthcare operations.
Minimizing the Attack Surface
One of ransomware’s most common tactics is exploiting compromised credentials to infiltrate systems. Imagine an attacker finding their way into your network via a dormant account left active after an employee’s departure. IGA eliminates these vulnerabilities by ensuring that access permissions are regularly reviewed and updated. As employees join, move roles, or leave the organization, their access rights are promptly granted, adjusted, or revoked. This ongoing oversight significantly reduces potential entry points, making it far harder for attackers to gain a foothold.
Enforcing Least Privilege
Once inside a system, ransomware often seeks to escalate its reach by exploiting excessive permissions. For instance, an attacker might leverage admin-level access to move laterally across the network and access critical data. Here, IGA steps in with enforcement of the principle of least privilege—users and applications only get access to what they need, nothing more. This containment strategy stops attackers in their tracks, limiting the damage they can do and safeguarding sensitive patient data.
Enhancing Visibility to Detect Threats Early
Ransomware doesn’t strike out of the blue; it often leaves a trail of subtle warning signs—unusual login times, unauthorized access attempts, or patterns of behavior that don’t align with normal activity. An effective IGA framework continuously monitors and audits user activity, giving security teams real-time insights into potential threats. With this level of visibility, anomalies can be detected early, enabling swift and precise action to neutralize the threat before it escalates.
Accelerating Response Times During a Breach
In the chaotic aftermath of a ransomware breach, time is of the essence. Delayed responses can give attackers the opportunity to encrypt critical systems or spread their reach across the network. IGA centralizes identity management, allowing security teams to act quickly—locking down compromised accounts, isolating affected systems, and cutting off the attacker’s access. This rapid response capability can be the difference between containing a breach and widespread operational disruption.
Key Components of a Resilient IGA Framework
Building a strong IGA framework starts with implementing a few critical components. These can limit the avenues ransomware can exploit:
- Identity Lifecycle Management: From the moment an employee joins the organization to their last day, their access is carefully managed. IGA ensures employees, contractors, and partners receive the right access during onboarding, and permissions are promptly adjusted or revoked when roles change or employment ends. This reduces the chances of overprovisioned accounts becoming a gateway for attackers.
- Role-Based Access Controls (RBAC): By aligning access policies with job responsibilities, RBAC ensures that users only access the resources they need for their role. This prevents attackers from moving laterally across systems once they gain a foothold.
- Multi-Factor Authentication (MFA): Adding an extra layer of security through MFA makes it far harder for attackers to exploit stolen credentials.
- Monitoring & Auditing: Real-time activity tracking ensures any unusual behavior—such as failed login attempts or access outside normal hours—is flagged immediately, enabling a swift and targeted response.
Steps to Implement IGA in Your Healthcare Organization
Healthcare organizations looking to strengthen their ransomware defenses can take practical steps to deploy IGA effectively:
- Begin with a thorough review of existing access permissions to identify and address overprovisioned accounts or outdated credentials.
- Implement multi-factor authentication across critical systems to add an extra layer of security.
- Define clear role-based access control policies tailored to the specific responsibilities of each role. Ensure access is limited to the minimum required for each role.
- Integrate IGA into the broader security ecosystem, combining it with firewalls, intrusion detection systems, endpoint protection, and threat monitoring to build a comprehensive defense.
- Even with the most advanced IGA systems in place, employees are often the weakest link in security. Train them regularly, equip them to recognize phishing attempts, and follow security best practices, further strengthening the organization’s defense posture.
