Pen Testing for Radiology

Learn about the Areas of Pen testing for Radiology including IoT Devices, DICOM Images, PACS and RIS

Penetration testing, often referred to as “pen testing” or “ethical hacking,” is a proactive security assessment approach used to identify vulnerabilities and weaknesses within a computer system, network, or application. In the context of radiology, penetration testing is specifically designed to evaluate the security of medical imaging systems, including Picture Archiving and Communication Systems (PACS), Radiology Information Systems (RIS), medical devices and associated network and application infrastructure. The primary goal of penetration testing in radiology is to simulate real-world cyberattacks and assess the system’s ability to withstand and defend against these threats as the Radiology industry increasingly handles sensitive electronic patient data with many partners, vendors and customers. 

 

Areas of Pen Testing for Radiology

There are 4 specific areas of pen testing that are of relevance to organizations that work with medical imaging and radiology. They are:

  1. Network Testing
  2. Application Testing
  3. Mobile App Testing
  4. IoT Testing
4 areas of penetration testing for radiology

1. Network Testing for Radiology

Radiology organizations operate various external-facing infrastructures essential for engaging with hospitals, referring physicians, and other collaborators. However, the existence of these interfaces poses significant risks to the organization’s security if not adequately fortified. Ensuring the robustness of network security protocols becomes paramount in safeguarding sensitive data and maintaining the integrity of operations. Proactive measures, including comprehensive vulnerability assessment and penetration testing of network systems, are imperative to identify vulnerabilities and implement necessary defenses, thereby mitigating potential breaches and protecting the confidentiality of patient information.

 

2. Application Testing

Radiology organizations must also prioritize application testing, particularly for Picture Archiving and Communication Systems (PACS), which store vast patient records accessed by numerous radiologists. As part of Vulnerability Assessment and Penetration Testing (VAPT), rigorous evaluation of PACS system infrastructure and applications is essential to verify correct configuration and fortify against potential vulnerabilities. Additionally, given the interconnected nature of many external-facing applications in the radiology domain, comprehensive testing within this context becomes imperative. This includes ensuring the secure implementation of DICOM (Digital Imaging and Communications in Medicine) protocols, which facilitate the exchange of medical images and related information. We conduct a DICOM vulnerability assessment (DVA) to meet this objective. Such assessments serve to identify weaknesses in the system’s architecture and application interfaces, enabling the implementation of robust security measures to safeguard patient data and uphold operational integrity.

 

3. Mobile App Testing

Mobile applications utilized by radiologists frequently establish connections to backend systems to process and display medical images. However, vulnerabilities within these mobile apps pose a significant risk, potentially compromising the integrity of the backend infrastructure if left unidentified and unaddressed. Therefore, it is crucial to conduct thorough testing of mobile applications to uncover any vulnerabilities promptly and implement necessary fixes. This proactive approach ensures the security and stability of the entire system, safeguarding sensitive medical data and maintaining seamless functionality for healthcare professionals.

 

4. IoT Testing

In radiology, numerous devices such as CT, MRI, and X-ray machines are connected to the hospital networks or provider systems. Unfortunately, many of these devices run on outdated software and lack regular patches for identified vulnerabilities. Vulnerability Assessment and Penetration Testing (VAPT) play a crucial role in uncovering these issues, providing a structured framework for prioritizing and addressing them. By identifying vulnerabilities in connected radiology devices, VAPT ensures a proactive approach to cybersecurity, mitigating potential risks and enhancing the overall safety and reliability of diagnostic equipment within healthcare settings.

Pen Testing versus Vulnerability Assessment

Explore differences between Pen Testing and Vulnerability Assessment, whether you need both or just one, the cost, time & applicability for regulatory compliance

Feeling confused about security assessments? Are you unsure if a Vulnerability Assessment or Penetration Test is the right assessment for your organization? While both aim to test your defenses and security postures, they take very different approaches. This blog will untangle the mysteries of Vulnerability Assessments and Penetration Testing, helping you choose the ideal champion to evaluate your security posture.

Vulnerability Assessments (VAs) leverage automated tools to scan for known vulnerabilities in your software and systems. They provide a high-level view of potential issues based on documented weaknesses. This approach is cost-effective and efficient, making it ideal for regular checkups.

Penetration Testing (PT) simulates real-world attacker behavior, actively exploiting existing vulnerabilities to measure their impact. This in-depth assessment reveals how attackers might gain access and cause damage. However, Penetration Tests are more complex, requiring specialized skills and manual effort, leading to higher costs.

Organizations look for these security assessments usually for legal, contractual or regulatory purposes. Once you understand the business objective(s) for your assessment, you can select the right option or probably conduct both tests. However, in our experience as cybersecurity professionals for over 12 years, leveraging the strengths of both VA and PT at different times is ideal for your cybersecurity strategy. 

 

Comparing Pen Testing and Vulnerability Assessment

Vulnerability Assessment and Penetration Testing (Pen Testing) are both critical components of a comprehensive cybersecurity strategy, but they serve different purposes and have distinct methodologies. Here’s a comparison of the two: 

Comparing Pen Testing & Vulnerability Assessment

1. Purpose

Vulnerability Assessment: The primary goal of a vulnerability assessment is to identify, assess, and categorize vulnerabilities in an organization’s systems, networks, and applications. It focuses on finding weaknesses in the security posture without exploiting them. It aims to provide a snapshot of potential weaknesses that could be exploited by attackers.

Pen Testing: Pen Testing, on the other hand, involves actively simulating real-world cyberattacks to exploit vulnerabilities and determine the extent to which an attacker can gain unauthorized access or compromise systems. The primary purpose is to evaluate an organization’s security posture and measure its ability to withstand attacks if they are attacked.

 

2. Scope & Frequency of Testing

Vulnerability Assessment: It usually has a broader scope, focusing on identifying as many vulnerabilities as possible, including low-risk ones. It provides a comprehensive list of potential weaknesses.

Pen Testing: Pen testing has a narrower scope and typically focuses on a specific target or set of targets. It aims to demonstrate the impact of exploited vulnerabilities and assess the overall security posture.

 

3. Methodology

Vulnerability Assessment: It typically involves automated or manual scans of systems and networks to identify known vulnerabilities. The assessment can include vulnerability scanning tools, configuration reviews, and system analysis.

Pen Testing: Pen testing involves ethical hackers (penetration testers) actively trying to exploit vulnerabilities to understand their potential impact and determine if unauthorized access or data breaches are possible. This may include attempting to gain unauthorized access, privilege escalation, social engineering, network probing, data exfiltration, or other attack scenarios.

 

4. Reporting

Vulnerability Assessment: The output of a vulnerability assessment is a list of identified vulnerabilities, their severity ratings, and recommendations for remediation. It provides a roadmap for improving security but doesn’t include detailed exploitation scenarios.

Pen Testing: Pen testing reports include information on the vulnerabilities exploited, the impact of successful attacks, the techniques used, and recommendations for mitigating the risks. These reports are more in-depth and provide actionable insights based on actual attack simulations.

5. Regulatory Compliance

Vulnerability Assessment: Vulnerability assessments are often almost required to comply with various regulations and standards, such as PCI DSS, ISO 27001, SOC 2, HIPAA, NIST Cybersecurity Framework, NIST 800-171, CMMC 2.0, etc. This is considered as the minimum required security program for several organizations.

Pen Testing: Penetration testing is also required, at times, by regulations and security standards, and it is more focused in the areas where customer data is stored. Organizations in the finance industry, product/cloud companies and the healthcare sector are required to conduct the pen testing as the cost of breaches is too high if the services/products are not secured properly. Pen testing is required in any certification audit including SOC 2 & ISO 27001, apart from several compliance standards including PCI DSS, HIPAA, NIST Cybersecurity Framework, NIST 800-171, CMMC 2.0, etc.

 

6. Cost & Time

Vulnerability Assessment: Typically carried out through automated processes, this operation can take anywhere from a few hours to several hours to complete. The process, which includes identifying vulnerabilities and validating the results, is generally completed within a few days. The cost for this engagement usually begins at around USD 2,500.

Pen Testing: A considerable amount of work goes into collecting public information, conducting analysis, identifying vulnerabilities, and executing exploitation, including privilege escalation. Depending on the type of penetration testing – whether it’s network, application, or other asset types – the engagement typically spans 2 to 6 weeks. The cost for these services starts at approximately USD 15,000.

 

7. Benefit to your Cybersecurity Strategy

Vulnerability Assessment: The assessment tells you how your systems are configured and which policies & procedures you need to be changed to enhance security.

Pen Testing: It tells you how secure your systems are and which security controls are not implemented. After a Pen Test, you need to review your security tech & industry-specific best practices.

Do you need Pen Testing and Vulnerability Assessment or just one?

Vulnerability assessments are focused on identifying vulnerabilities, while penetration testing involves actively exploiting these vulnerabilities to assess their real-world impact. Both approaches are valuable in a comprehensive cybersecurity strategy, with vulnerability assessments providing continuous monitoring and early detection of weaknesses and penetration testing helping organizations understand their readiness to defend against sophisticated attacks. Both are valuable tools in a cybersecurity program, and organizations often use a combination of both to strengthen their overall security posture.

Compliance Driven Decisions: If legal, contractual, or regulatory requirements demand specific assessments, you need to follow the mandated standards or clauses.

Understanding Your Needs: If the decision isn’t dictated by external factors, consider your specific needs. Vulnerability Assessments are excellent for regular scanning and identifying broad areas for improvement. They are cost effective and help you categorize vulnerabilities. Pen Testing is invaluable for uncovering deeper vulnerabilities and understanding their real-world consequences.
