• Social Engineering VAPT: Assesses human vulnerabilities through simulated phishing, pretexting, and other social engineering attacks.

VAPT Methodologies: How to Approach the Testing?

Within each of the VAPT types described above, different testing methodologies often called “box” testing can be employed, depending on the desired level of access and knowledge of the testers:

• Black Box Testing: Simulates an external attack. Testers have no prior knowledge of the target system’s internals.
• White Box Testing: Testers have full knowledge of the target system, including source code, diagrams, and configurations.
• Gray Box Testing: A hybrid approach. Testers have partial system knowledge, balancing external and internal perspectives.

The VAPT Process: A Holistic Approach to Security

Here’s a breakdown of the typical VAPT process:

Phase 1: Planning and Scoping

This crucial initial phase sets the stage for the entire VAPT engagement. It involves defining objectives, scope, timeline, and resources.

Phase 2: Vulnerability Assessment (VA)

This phase focuses on identifying and documenting potential security weaknesses:

• Information Gathering: Collecting data about the target systems, including network architecture, software versions, and configurations.
• Vulnerability Scanning: Using automated tools to scan the target systems for known vulnerabilities.
• Vulnerability Analysis: Analyzing the results of the vulnerability scan to identify and prioritize the most critical vulnerabilities.
• VA Reporting: Generating a report that documents all identified vulnerabilities, their severity levels, and recommended remediation steps.

Phase 3: Penetration Testing (PT)

This phase simulates real-world attacks to test the exploitability of identified vulnerabilities:

• Penetration Testing Planning: Defining the scope and objectives of the penetration test, based on the findings of the vulnerability assessment.
• Exploitation: Attempting to exploit the identified vulnerabilities in a controlled environment to demonstrate the potential impact of a successful attack.
• Post-Exploitation: Assessing what an attacker could achieve after gaining access to a system, such as escalating privileges, moving laterally within the network, or exfiltrating data.
• PT Reporting: Generating a detailed report that documents the exploited vulnerabilities, the potential impact of the attacks, and recommended remediation steps.

Phase 4: Reporting and Remediation

This phase focuses on communicating the findings and addressing the identified vulnerabilities. It combines VA and PT reports to generate comprehensive VAPT reports. Remediation planning and implementation are done in this phase to mitigate the identified vulnerabilities.

Phase 5: Re-testing and Follow-up

This final phase verifies the effectiveness of the remediation efforts by verifying fixes, generating final report, and implementing ongoing monitoring.

VAPT Audits: Ensuring Compliance and Strengthening Security

Many industry regulations and standards (e.g., ISO 27001, PCI DSS, HIPAA, SOC 2) require regular VAPT audits. These audits provide independent verification of your security posture and demonstrate due diligence to regulators, customers, and partners. This audit involves a thorough review of your security controls, vulnerability assessments, penetration testing results, and remediation efforts. It helps identify gaps in your security program and ensures you are meeting compliance requirements. 

Beyond compliance, a VAPT audit can also provide valuable insights into your overall security effectiveness and identify areas for improvement. A well-conducted audit can give you confidence in your security posture and help you prioritize future security investments.
