VAPT Security Testing Services | VAPT Audit Company

VAPT Service is the combination of two different Security Services one is Vulnerability Assessment (VA) & Penetration Testing (PT). The tests have different powers and are often shared to achieve a more complete vulnerability analysis. Both Services have their area for securing your network & application.

Vulnerability Assessment Tools discover which vulnerabilities are present, but they do not differentiate between flaws that can be exploited to cause damage and those that cannot. Vulnerability scanners alert companies to the preexisting flaws in their code and where they are located. Penetration tests attempt to exploit the vulnerabilities in a system to determine whether unauthorized access or other malicious activity is possible and identify which flaws pose a threat to the application. Penetration tests find exploitable flaws and measure the severity of each. A penetration test is meant to show how damaging a flaw could be in a real attack rather than find every flaw in a system. Together, Vulnerability Assessment and Penetration Testing Tools provide a detailed picture of the flaws that exist in an application and the risks associated with those flaws.

What is Vulnerability Assessment?

Vulnerability Assessment is also known as Vulnerability Testing, is a software testing type performed to evaluate the security risks in the software system to reduce the probability of a threat.

A vulnerability is any mistakes or weakness in the system security procedures, design, implementation or any internal control that may result in the violation of the system’s security policy. In other words, the possibility for intruders (hackers) to get unauthorized access.

Vulnerability Analysis depends upon two mechanisms namely Vulnerability Assessment and Penetration Testing(VAPT).

What is penetration testing

A penetration test, also known as a pen test, is a simulated cyberattack against your computer system to check for exploitable vulnerabilities. In the context of web application security, penetration testing is commonly used to augment a web application firewall (WAF).

Pen testing can involve the attempted breaching of any number of application systems, (e.g., application protocol interfaces (APIs), frontend/backend servers) to uncover vulnerabilities, such as unsanitized inputs that are susceptible to code injection attacks.

Insights provided by the penetration test can be used to fine-tune your WAF security policies and patch detected vulnerabilities.

Why do VAPT

  • It is important for the security of the organization.
  • The process of locating and reporting the vulnerabilities, which provides a way to detect and resolve security problems by ranking the vulnerabilities before someone or something can exploit them.
  • In this process Operating systems, Application Software and Network are scanned to identify the occurrence of vulnerabilities, which include inappropriate software design, insecure authentication, etc.

Vulnerability Assessment and Penetration Testing (VAPT) Process

  1. Goals& Objectives: – Defines goals and objectives of Vulnerability Analysis
  2. Scope: – While performing the Assessment and Test, the Scope of the Assignment needs to be clearly defined.

The following are the three possible scopes exist:

  • Black Box Testing: – Testing from an external network with no prior knowledge of the internal network and systems.
  • Grey Box Testing: – Testing from either external or internal networks, with the knowledge of the internal network and system. It’s the combination of both Black Box Testing and White Box Testing.
  • White Box Testing: – Testing within the internal network with the knowledge of the internal network and system. Also known as Internal Testing.
  1. Information Gathering: – Obtaining as much information about the IT environment such as Networks, IP Address, Operating System Version, etc. It applies to all the three types of Scopes such as Black Box Testing, Grey Box Testing, and White Box Testing
  2. Vulnerability Detection: -In this process, vulnerability scanners are used, they will scan the IT environment and will identify the vulnerabilities.
  3. Information Analysis and Planning: – It will analyze the identified vulnerabilities, to devise a plan for penetrating the network and systems.

Vulnerability Testing Methods

Active Testing

  • Inactive Testing, a tester introduces new test data and analyzes the results.
  • During the testing process, the testers create a mental model of the process, and it will grow further during the interaction with the software under test.
  • While doing the test, the tester will actively involve in the process of finding out the new test cases and new ideas. That’s why it is called Active Testing.

Passive Testing

  • Passive testing, monitoring the result of running software under test without introducing new test cases or data

Network Testing

  • Network Testing is the process of measuring and recording the current state of network operation over some time.
  • Testing is mainly done for predicting the network operating under load or to find out the problems created by new services.
  • We need to Test the following Network Characteristics:-
  • Utilization levels
  • Number of Users
  • Application Utilization

Distributed Testing

  • Distributed Tests are applied for testing distributed applications, which means, the applications that are working with multiple clients simultaneously. Testing a distributed application means testing its client and server parts separately, but by using a distributed testing method, we can test them all together.
  • The test parts will interact with each other during the Test Run. This makes them synchronized appropriately. Synchronization is one of the most crucial points in distributed testing.

Penetration testing methods

External testing

External penetration tests target the assets of a company that is visible on the internet, e.g., the web application itself, the company website, and email and domain name servers (DNS). The goal is to gain access and extract valuable data.

Internal testing

In an internal test, a tester with access to an application behind its firewall simulates an attack by a malicious insider. This isn’t necessarily simulating a rogue employee. A common starting scenario can be an employee whose credentials were stolen due to a phishing attack.

Blind testing

In a blind test, a tester is only given the name of the enterprise that’s being targeted. This gives security personnel a real-time look into how an actual application assault would take place.

Double-blind testing

In a double-blind test, security personnel has no prior knowledge of the simulated attack. As in the real world, they won’t have any time to shore up their defenses before an attempted breach.

Targeted testing

In this scenario, both the tester and security personnel work together and keep each other apprised of their movements. This is a valuable training exercise that provides a security team with real-time feedback from a hacker’s point of view.
