How does Security Testing help in validating the Healthcare Ecosystem

 

The healthcare ecosystem’s dependence on digital technologies to deliver better services to patients and other stakeholders has made it vulnerable to security threats. If statistics are to be believed then healthcare companies across the world are going to cough up a whopping $6 trillion in damages due to security breaches in 2020 (Source: PhoenixNAP.) Modern-day healthcare applications store sensitive patients’ data, which has often led to medical identity theft necessitating the need for rigorous software application security testing. The critical patients’ data may include identity details, payment information, bank account details, history of morbidity, and insurance details, among others. The breach of any of this information can be lethal and devastating, both for the patients and the healthcare facility. 

Why is the healthcare security system important?

Cybercriminals are targeting critical patient information to steal identities using methods or tools like phishing, malware, or ransomware. To pre-empt such attacks a robust application security testing strategy needs to be put in place with the following guidelines.

•  Top-most priority to be given to ensure security for the vital facets

•  The application security testing methodology should remodel the framework for data security, verification, audit logging, and many more

• The other aspects of security testing would include business logic testing, data validation testing, session management testing, DOS testing, Ajax testing, configuration management testing, and OWASP   testing to check for vulnerabilities such as SQL injection and XSS.

What are the types of healthcare security testing?

Security testing covers a range of tests to verify and validate the robustness of the healthcare application and its ability to fend off various security threats.

Penetration testing: In this type of testing, ethical hackers try to gain entry into the healthcare application by exploiting its vulnerabilities. The process performed manually or using automated testing, gathers information about the application in terms of the possible entry points. Thereafter, the hacker attempts to break into the application and verifies its level of system protection.

Application-level testing: Also known as app-level testing, the technique ensures the software application doesn’t execute any malicious actions. Here, specific security-related scenarios are validated by conducting functional testing.

DDoS testing: In this type of interactive application security testing, simulated DDoS (Distributed Denial of Service) attacks are conducted with real traffic to understand the level of protection offered by the application to thwart DDoS attacks.

Security code review: It mitigates potential security vulnerabilities in the software code early on and prevents costly and time-consuming fixes later. It serves as a final review to check the application’s safety before launch.

How does software application security testing benefit the healthcare domain

Security testing for the healthcare domain gives insight into the robustness of the healthcare application and its ability to face cyber threats. The benefits of employing software application security testing include:

Protecting PHI: This type of testing Identifies and fixes all vulnerabilities associated with Protected Health Information (PHI) and checks if PHI complies with the HIPAA standards.

Data storage validation: It checks if the data storage mechanism, in encrypted or plain-text form, is safe and secure. Besides, it analyses the security solution, encryption methods, and data management techniques and helps to detect any security issues with the application’s database.

Data transmission validation: Software applications transmit data across cloud, mobile devices, and email, which should be properly encrypted to prevent any unauthorized access at any stage.

Identity validation: Detects vulnerable access points that could be exploited by hackers, especially the areas covering identity management. The software application security testing helps to mitigate any breach of patient privacy and strengthen the mechanism for identity management.

Risk assessment before deployment: Once the application with security-related vulnerabilities is deployed, it may cause havoc in the form of security breaches. The application security testing services offer the opportunity to identify and fix all security-related vulnerabilities in the application. This ensures the application is bereft of any security issue and protects the customer from carrying out any type of financial transaction.

Builds trust and confidence: Security testing ensures the application is compliant with the HIPAA standard. This helps to build the trust of your clients in the application and boost its brand equity.

Conclusion

The cybersecurity dimension is expanding at a phenomenal rate coupled with growing incidences of security breaches. To restore customer confidence and prevent such incidences, healthcare security testing should be conducted rigorously.

How to Secure your Web Applications - Complete Guide

Digitization has led to the development of web applications, websites, and other tools. Besides changing the way that we share information, interact, or do business, these digital elements have transformed our lives for the better. Enterprises, in order to stay flexible, profitable, and competitive, are moving their operations online. This way, they allow their employees, clients, customers, and other stakeholders to stay connected 24x7. Also, employees working in remote offices across countries can interact and collaborate in real-time by using such technologies.

The introduction of Web 2.0 has brought convenience, speed, choices, and quality on a platter for the customers. The growing customers’ appetite for top-notch web applications has led businesses or entities to share sensitive data all across the value chain. The examples of e-commerce stores and online banking exemplify this trend. If such advancements have brought enormous benefits for individuals, businesses, and organizations, they have attracted hackers and scammers as well.

The news about malware, ransomware, trojans, and viruses playing havoc has become common now. In fact, cybercrime has become a $1.5 trillion industry as we move into the year 2020. It has the potential to push individuals, businesses, and organizations into a downward spiral. The cumulative effect of cybercrime has given rise to the industry of web application security.

Let us take you through the ways to secure your web applications in the form of a guide. Here, the focus would be on conducting a comprehensive web application security audit encompassing web application security testing.

Assessing the Target Web Application: The process can involve the use of an automated web vulnerability scanner provided the pre-scan activities are already done. However, the procedure is not foolproof and can give rise to several false positives as well. This happens as the web vulnerability scanners are meant to scan a number of complex web applications. The users, thus, need to align these scanners to the specific business needs.

The web application security testing can begin by conducting a manual assessment of the target web application. Thus, you can get familiarized with the architecture and topology of the web application. Find out about the directory, file structure, number of pages, and files present in the application. Also, know about the application’s root directory, source code, online forms, and URL structure. Since there are a number of vulnerabilities specific to web technologies, it is better you know the one used to develop the application - PHP and .NET, among others. Find out if the web application had crawled from the black-box scanner before launching the scan. Remember, if the web application is not crawled and leaves out some parts or parameters, then securing the application will not happen.

Denial of Service (DOS) Checklist: Web applications cannot distinguish between valid traffic and a malicious attack. Among the reasons, the uselessness of IP addresses as identification credentials comes at the top. For example, during a distributed attack the web application cannot identify a real attack from multiple users reloading at the same time. In this type of software application security testing, the number of sessions per user should be checked and regulated, if need be.

Penetration Testing: Make sure all the web penetration tools are available in a centralized repository supporting the import and export of data. The application security testing services should use penetration testing - manually as well as using tools to check for logical vulnerabilities and to audit the application.

Web Application Firewall (WAF): It can analyze web traffic emanating from IP addresses containing both HTTP and HTTPS. This way WAF can identify malicious traffic that works at the application layer. It can block connections to known vulnerabilities in a web application thereby preempting any malicious attack. However, it comes with a few shortcomings as well:

• Ability to detect only known security vulnerabilities
• Depends on the expertise of the user
• No fixing of security holes in web applications

The software application security testing should be conducted throughout the SDLC and not when the application goes live. It comprises of several methods such as:

• Using a black-box scanner
• Conducting a manual source code audit
• Identifying coding issues using an automated white-box scanner
• Penetration testing
• Conducting a manual security audit

Conclusion

Web applications can be the ideal conduit for the ingress of malicious codes into an IT system. However, the quality of such applications can be enhanced, and security strengthened by using the right vulnerability scanner. By employing a focused application security testing methodology, both logical and technical vulnerabilities can be identified and fixed. The other avenues include limiting remote access, switching off unnecessary functionalities, using accounts with limited privileges, segregating live environments from development and testing, installing security patches, and staying informed.
