What is VAPT?

VAPT is the amalgamation of two popular security testing strategies - Vulnerability Assessment and Penetration Testing. It combines the forces of both these methods to upscale and strengthen security testing.

It significantly boosts the security posture of an organization. VAPT offers a deeper security assessment with automated vulnerability scanning to expose weaknesses and exploit these weaknesses with penetration testing.

It doubles the power to make security audits more precise, effective, and comprehensive. Apart from boosting security posture, it also enables organizations to stay compliant with industry standards and regulations.

Why Do You Need VAPT?

VAPT offers an edge over traditional testing methods by evaluating systems and applications at a greater depth. As a result, it helps discover vulnerabilities more accurately, allowing your organization to mitigate cyber risks effectively. Besides, it also offers proactive measures against cyber threats. Let’s understand why it is necessary for your organization.

Shift-Left Approach

Continuous testing and regular VAPT reports improve overall security practices in the SDLC. Besides, it also shifts security testing to the left, which helps identify and remediate vulnerabilities before an application reaches production.

Shifting security testing left means an application is evaluated at the testing and staging phases, addressing any vulnerabilities before deployment. It enables your organization to adopt a security-first mindset by making it an integral part of your SDLC.

Improve Security Posture

Can a one-time security test help you identify and fix all the risks? Well, the answer is plain no, because applications evolve over time and change more frequently today than ever. So, once-in-a-time security tests aren’t relevant anymore if you need robust security.

VAPT offers continuous security audits instead of one-time testing. As a result, it helps boost security posture by constantly improving the application. Indeed, regular risk assessment with VAPT testing will enable you to discover emerging threats and keep your application secure against them.

Ensure Compliances

Different sectors have diverse compliance requirements. For example, there are some sectors like healthcare and fintech where stringent compliance is imposed. So, they must strictly adhere to compliance to avoid heavy penalties and legal actions.

VAPT helps organizations meet compliance standards like HIPAA, PCI DSS, GDPR, SOC2, and more by providing thorough assessment and compliance reports. VAPT reports offer more insights into the threat landscape, allowing organizations to mitigate cyber risks effectively.

Proactive Risk Mitigation

VAPT testing is a proactive vulnerability management strategy that allows you to mitigate security risks before attackers exploit them. Unlike a reactive security approach that focuses on responding and mitigating risks after a cybersecurity incident occurs, it stresses building robust security shields to prevent or mitigate cyber risks in the first place.

Manage Reputation

Cybersecurity incidents not only cause data loss but also degrade your reputation. Even a single incident of data breach can shake users’ confidence in your business. It will tarnish your reputation, and negative words will spread in the market.

By conducting VAPT assessments, organizations can demonstrate their commitment to ensuring data protection. This will maintain stakeholders’ confidence in your organization as they will be assured that their data is protected.

Broader Risk Assessment

While automated vulnerability assessment can help you identify surface-level vulnerabilities, penetration testing offers deeper insights. But combining them can help you detect most threats. Indeed, vulnerability scanning identifies common vulnerabilities, misconfigurations, and weaknesses by analyzing applications and networks.

Penetration testing involves exploiting the vulnerabilities identified to try to gain unauthorized access. It helps gain insights into an application’s threat landscape and its ability to withstand potential cyberattacks. Based on this broader insight, organizations can build robust security strategies to prevent cyber risks.

How Does the VAPT Assessment Take Place?

As a systematic approach, a typical VAPT audit takes place in many steps as mentioned below.

Scoping

This is the first step of the VAPT security testing approach. It involves defining the scope of testing and determining which asset to be tested. Besides, it also involves deciding on compliance prioritization and selecting the testing methodology.

Vulnerability Scanning

The next step in this process is vulnerability scanning. Well, this step involves evaluating the target with automated vulnerability scanning to uncover known weaknesses like OWASP Top 10. It uncovers a wide range of vulnerabilities and misconfigurations, providing an insight into attack vectors. There are two popular methods of vulnerability scanning – DAST and SAST.

• Static Application Security Testing (SAST) analyzes the source code of an application to identify vulnerabilities.
• On the other hand, DAST (Dynamic Application Security Testing) tests applications at runtime to expose vulnerabilities. It identifies vulnerabilities in real time.

Penetration Testing

Penetration testing is the next step that simulates real-world attacks. It involves trying to exploit the vulnerabilities identified in the previous step. By imitating an attacker’s actions, it tries to exploit and gain unauthorized access to the target. This kind of testing helps gain deep insights into an organization’s threat landscape and evaluates the target’s resilience to actual attacks.

Reporting and Remediation

After all the above steps, you will have a detailed VAPT test report providing information like the vulnerabilities identified, how they were exploited, and recommendations to remediate them. This step also involves prioritizing vulnerabilities and creating a plan to address them. The remediation might involve creating patches, removing components, or implementing new functionalities.

Rescanning to Verify Remediation

Once vulnerabilities have been patched, another VAPT test is performed to make sure that the weaknesses have been fixed. If everything is perfect, a VAPT certificate is generated that facilitates a compliance audit.

Different Methodologies to Conduct VAPT

There are different methodologies to conduct Vulnerability Assessment and Penetration Testing (VAPT). These methodologies are known as black box testing, white box testing, and gray box testing. Let’s learn more about them.

Black Box Testing

It is a testing scenario in which the tester doesn’t have knowledge of the internal workings of a system or application. Besides, the tester doesn’t have access to source code, functionalities, and documents either. The purpose of this kind of testing is to simulate real-world attacks to identify security flaws. The tester analyzes the target from outside in attempting an intrusion and tracking the responses.

White Box Testing

It is the opposite of black box testing. This is because the tester has full knowledge of the target’s architecture, functions, and structure with access to source code. In this case, the tester tries to evaluate the possibility of an insider attack. It also helps discover source code-related vulnerabilities.

Gray Box Testing

While white box and black box testing are opposite to each other, they can produce more impactful results when combined. Indeed, gray box testing is the method you can count on for being the combination of both. It ensures a balance between those two methods. In this case, a tester has a limited amount of information to conduct tests. So, it uses both kinds of tactics to assess the target application or system.

Understanding the Different Vulnerability Assessment and Penetration Testing (VAPT) Types

The following are the different types of VAPT that you can perform to analyze diverse assets to discover and fix vulnerabilities for enhanced security.

Network Testing

It involves evaluating network defenses by leveraging ethical hacking methodologies. Network testing thoroughly analyzes the network assets to identify data storage and transfer vulnerabilities that attackers could exploit to penetrate an organization’s internal network. Techniques like scanning, fuzzing, exploitation, and privilege escalation are used to uncover these weaknesses.

Web Application Testing

It involves analyzing web applications with automated tests to uncover security vulnerabilities like improper input validation, weak authentication and authorization, and business logic flaws. A tester uses various techniques like injecting malicious code, manipulating sessions, and exploiting logic flaws.

API Testing

API testing involves imitating real-world attacks to uncover vulnerabilities like IDOR, injection flaws, weak authentication, and more. There are techniques like manipulating data packets to try to exploit API vulnerabilities and identify the potential risks.

Mobile App Testing

In this testing, static and dynamic analysis is used to discover security flaws in mobile apps’s code, APIs, and data storage. This analysis helps uncover weaknesses and strengthen the app’s security. It involves exploiting business logic vulnerabilities, exposing sensitive data in transit, and other techniques to discover CVEs.

Cloud Testing

It involves VAPT audits for cloud environments to expose vulnerabilities related to APIs, storage, access controls, and configurations. There are techniques like API fuzzing, cloud configuration, serverless function exploitation, and more to unearth vulnerabilities in cloud environments.
