What Is Vulnerability Assessment and Penetration Testing (VAPT)?

What Is Vulnerability Assessment and Penetration Testing (VAPT)?

Vulnerability Assessment and Penetration Testing (VAPT)

Vulnerability Assessment and Penetration Testing (VAPT Testing) is a technique for locating security flaws in software or a computer network. VAPT is sometimes misinterpreted as two distinct testing processes. These two, on the other hand, should be merged in order to produce better results. The goal of the Vulnerability Assessment is to identify and correct bugs. Penetration testing investigates and abuses the system to determine whether a vulnerability exists.

Watch this video, to get a gist on Cyber Security Training:

What is a Vulnerability Assessment?

The practice of finding and measuring known security vulnerabilities in an environment is known as vulnerability assessment. It is a high-level evaluation of your information security posture that finds flaws and suggests mitigation solutions to either eliminate or reduce those flaws to an acceptable risk level.

Vulnerability Assessments Follow the general steps outlined below:

  1. Inventory the assets and resources of the system.
  2. Assign the monetary and contextual value to the resources.
  3. Determine any security flaws or potential dangers to each resource.
  4. Reduce or eliminate the most serious threats to important resources.

Why Vulnerability Management?

Why Vulnerability Management?

Malicious code, Trojans and complex worms, botnets, DNS attacks, and spam sites were the most commonly reported cyber-attacks in the last 10 years. Today, however, cybercriminals are introducing new malware to the world, such as bitcoin wallet stealers, ransomware, and pos attacks, to name a few examples.

Information Security Requirements Transformation

Data security standards are evolving at dizzying speed, as hackers continue to seek new ways to smuggle malware into the system. As a result, businesses are having difficulty preparing for information security incidents.

Traditional security measures are ineffective in this circumstance

Long-term security solutions (intrusion detection systems, antivirus, encryption, preventive systems, patching, and so on) remain critical defenses against recognized threats. As intruders develop new methods for evading such controls, the effectiveness of such solutions diminishes with time.

Incident Identification Gaps

Due to almost unsolvable detection gaps in their design, organizations frequently lack the ability to detect data security issues.

How can I know if my firm requires a vulnerability assessment?

  • Vulnerability Assessment and Penetration Testing are commonly overlooked by organizations; nonetheless, every company is a potential target for hackers.
  • This is obvious given recent ransomware attacks. Take responsibility and ensure that appropriate security safeguards are in place to protect your application.
  • A Vulnerability Assessment should be performed once a year or after making significant changes to your application.

EPGC in Cyber Security and Ethical Hacking

The Root Causes of Vulnerabilities:

The fundamental reasons for a system’s vulnerability are misconfiguration and bad programming methods. The following are some of the reasons for vulnerability.

  1. Defects in hardware and software design
  2. Inadequately configured system a system linked to an unsecured network
  3. Password combinations that are ineffective
  4. Hardware or software that is complex

What is a Penetration Test?

Penetration testing, also known as PEN testing, is a security assessment intended to find vulnerabilities in a network, system, or application that an attacker could exploit. This is also known as ethical hacking, and these hackers are referred to as ‘white hat’ hackers. In order to identify key security weaknesses and cracks, ‘white hat’ hackers will emulate the genuine behavior of a cyber-criminal; they will also recommend remedies to these concerns.

Additional Penetration Testing Types and Services

Depending on the scope, a pentest can extend beyond the network to include social engineering attacks or physical security checks. Furthermore, there are two types of pentests: “clear box” and “glass box,” which are performed with little knowledge of the target systems and rely on the tester to conduct their own research.

Penetration Testing Take the General Steps Listed Below:

  1. Determining the scope
  2. Access exploitation and escalation attempts
  3. Testing for the gathering of sensitive data
  4. Cleanup and final reporting

Penetration Testing: Discover hidden flaws before hackers do

Penetration testing evaluates the entire application or system proactively to find where vulnerabilities may exist or address weaknesses, and it warns security professionals when existing security policies are violated. Security issues cannot be resolved until the root cause is discovered. Penetration testing goes beyond simply identifying security holes; it actually enters the system like a real-world hacker to determine how an intruder will access data. It illustrates the efficacy of security safeguards or rules and clearly identifies the gaps via which cyber-criminals can access the system.

Why VAPT is required?

When it comes to security, VAPT offers various advantages to a business; here are a few of them.

  1. Providing a detailed perspective of potential risks to an organization’s application.
  2. Assist the organization in spotting code errors that lead to cyber-attacks.
  3. Risk management is available.
  4. It safeguards the company’s reputation and finances.
  5. Applications are protected from both internal and external attacks.
  6. Protects the organization’s data from malicious attacks.

How Does VAPT Function?

The first stage of VAPT is determining which systems and applications need to be reviewed. This can be accomplished manually or with the use of a tool. After compiling the list, a VAPT tool is used to scan each system or application for vulnerabilities. These programs use a range of techniques to detect vulnerabilities, such as network mapping, port scanning, and banner grabbing.

Following the completion of the vulnerability assessment, a penetration test is performed on known vulnerable systems or applications. This test’s purpose is to exploit vulnerabilities in order to get access to sensitive data or control of the system.

What is a VAPT tool?

A VAPT tool performs a VA to identify areas of weakness and a PT to exploit those areas of weakness to get access. For instance, a VA might help identify weak encryption while the PA works to decipher it.

The VAPT tools do a vulnerability scan, provide a PA report, and sporadically execute code or payloads.

Types of Network VAPT

Types of Network VAPT

There are two types of network vulnerability assessments and penetration testing.

Internal VA

This only applies to the internal network. In terms of vulnerability screening, internal servers, firewalls, and data components such as database servers or file servers are crucial. Only vulnerability assessment is performed because the test is to be run from within the network; penetration testing is not. Internal security audits can be conducted either physically within the network premises or remotely within the network.

External VAPT

This type monitors the internet for the external perimeter. Because the testing is done from outside the premises, thorough penetration testing is probably certainly performed after the vulnerability assessment. The former use vulnerability scanning to detect security flaws or vulnerabilities, whilst the latter attempts to exploit those holes.

VAPT Report

A VAPT Testing report is a comprehensive examination of the vulnerabilities found during the security test. It describes the weaknesses, the danger they provide, and possible fixes. The Pentest Report includes detailed vulnerability analysis, as well as a POC (Proof of Concept) and remediation to address the most critical vulnerabilities. A good penetration test report will also include a score for each detected vulnerability as well as the extent to which it may impact your application/website.


The COVID-19 era has drastically affected how businesses operate online. During this time, we have seen more mature and advanced hackers target a diverse spectrum of businesses worldwide. VAPT must be performed on a regular basis to safeguard your firm from any threats.
