INTRODUCTION
With the development of the internet and the growing number of business entities in the digital domain, the importance of safety for networks hosted by such organisations cannot be overstated. Security methods such as the evaluation of vulnerabilities and penetration testing are critical in order to safeguard the networks and servers maintained by enterprises. To grasp these fundamental concepts, we will first learn about the two main notions, followed by an examination of their relevance, advantages, and disadvantages.
VULNERABILITY ASSESSMENT AND PENETRATION TEST
Vulnerability assessmentrefers to the process of determining and evaluating the weaknesses of an organisations servers, networks, and applications. This not only identifies gaps and security issues in an organisations networks but also gives a complete analysis of places that require a security patch-up through the use of specialised automated tools. A vulnerability evaluation is also performed to learn about the various activities that an attacker may engage in.
A penetration test, on the other hand, is an arsenal for replicating a real attack on a companys systems, networks, or applications. The purpose is to identify vulnerabilities that an assessment of vulnerabilities may have missed and to analyse the effectiveness of the security measures that have been deployed. Penetration testing is frequently carried out by security professionals who employ both automated and human methods to identify shortcomings and make recommendations for how to prevent them.
Vulnerability assessment and penetration testing, also known as VAPT, is an important practise for organisations looking to strengthen their defences against cybersecurity threats and defend themselves from cyberattacks. Organisations benefit from VAPT in a variety of ways, including enhanced cybersecurity posture, regulatory compliance, savings on expenses, and increased consumer trust. Choosing the correct sort of VAPT operations service and performing VAPT on a regular basis can assist organisations in identifying and addressing cybersecurity flaws before they get taken advantage of by hackers.
WHY CHOOSING VAPT?
VAPT is becoming more important for organisations because of the developing nature of technological hazards and the potential consequences of an effectively carried out cyber assault. VAPT protects organisations by exposing security flaws and offering information on how to resolve them. Organisations may use VAPT to keep ahead of possible cybersecurity threats and protect the security of their information technology infrastructure.
ADVANTAGES AND DISADVANTAGES OF CHOOSING VAPT
AdoptingVAPTin a company has numerous benefits. A few instances include:

• Enhanced Cybersecurity Mentality: VAPT supports organisations in identifying and addressing cybersecurity flaws before they are exploited by hackers. Organisations may keep ahead of possible dangers and reduce the risk of an attack being successful by frequently testing their information technology (IT) structures, applications, and systems.
• Compliance with Regulatory Obligations: VAPT can assist organisations in meeting cybersecurity regulatory obligations. Organisations that fail to comply with these requirements may suffer severe penalties and reputational harm.
• Cost Savings: Organisations may save money by discovering vulnerabilities before they trigger a breach. Cyberattacks may be expensive to repair, and the consequences can be long-lasting. Organisations can prevent cyberattacks by checking their IT infrastructure and computer systems on a regular basis.
• Increasing Customer Satisfaction: VAPT assures customers that the organisation takes cybercrime seriously and is taking precautions to safeguard their data. Customers are more worried about data confidentiality and safety in todays society. Organisations may develop trust with their consumers and enhance their image by proving that they have begun to take proactive actions to resolve these issues.

As is customary, there are certain significant downsides to implementing VAPT services. Among them are:

• Lack of Skills: It is highly doubtful if a pen-tester would uncover every security vulnerability or solve all issues when investigating vulnerabilities and giving an automated report.
• Extremely time-consuming:It requires considerable time since it does not include a thorough security examination. Pen-testing takes a longer period of time than vulnerability examination to evaluate a specific system and find attack vectors due to the greater test scope. His or her acts may also disrupt the businesss operations since they resemble a genuine attack.
• Cost-Incurring: Because it demands a significant amount of work, it may be a bit more costly, and some companies may be unable to budget for it. This may be especially true if the job is completed by a contracting business.
• Not a comprehensive test: It may give the appearance of security. If systems can withstand the bulk of penetration testing attempts, it may appear that they are entirely safe. Nonetheless, in the vast majority of cases, company security teams understand the concept of the technique and are prepared to detect and fight against it. Above all, genuine assaults are unanticipated and unplanned.

TYPES OF VAPT
There are several sorts of VAPT products and services, each of which has its own set of advantages and disadvantages. Understanding the distinctions between these services might assist organisations in selecting the best one for their requirements. Among them are:
Automated Vulnerability Assessment: An automated vulnerability assessment scans an organisations computer networks, applications, and systems for vulnerabilities using software tools. This procedure is rapid and efficient, and it generates a full report on the vulnerabilities in question and their impact levels. However, it may not always detect every weakness; therefore, human assistance may be required to detect more complicated concerns.
Manual Breach Testing: Handbook penetration testing entails simulating a cyber assault on an organisations IT infrastructure in order to find shortcomings that automated vulnerability scanners may not detect. Automated penetration testing aims to exploit vulnerabilities in order to identify their effects on the organisation and offer suggestions on how to remedy them. This procedure is time-consuming and costly, but it produces a more comprehensive assessment of an organisations cybersecurity posture.
API Penetration Testing: API penetration testing is a vital element of any organisations security architecture. As a companys data and infrastructure grow more accessible to the internet, the possibility of a breach becomes more serious than ever. APIs, however, are more than simply one single source of failure; they pose a significant danger to the confidentiality of a companys internal infrastructure.
Most businesses have a range of APIs that allow workers and third-party apps to access internal applications, information, and infrastructure. These APIs, in the wrong hands, may be used to propagate malware, collect data, and influence an organisations infrastructure from within.
Cloud testing: Cloud testing for vulnerabilities is a sort of security assessment that looks for weaknesses in the context of cloud computing that hackers may exploit. Cloud reconnaissance is used to assess the integrity of internet-based computing environments and establish whether a cloud providers security policies and controls are capable of withstanding attacks. These tests should be done both before and after a corporation moves apps and information to the cloud as part of an online providers security maintenance. As part of a companys cloud infrastructure security review, a third-party security firm would most likely undertake a cloud penetration test.
Project Red Team: A red team operation is hiring a crew of ethical hackers to mimic an assault on an organisations IT infrastructure. Red team activities can assist in identifying vulnerabilities that mechanical scans for vulnerabilities or human penetration testing may overlook. The mission of the red team is to achieve an objective. The objective of the red team is to provide an unbiased evaluation of an organisations cybersecurity posture and to emphasise deficiencies that must be filled. The approach is costly, but it provides an in-depth assessment of an organisations cybersecurity posture.
WHAT KIND OF VAPT ONE MUST CHOOSE ?
It is essential to select the correct kind of VAPT service to guarantee that the tests provide the most value for money. VAPT examinations can range greatly in comprehensiveness, breadth, dimension, and cost; thus, recognising the distinctions is critical. The answer to the issue of how many times one should do a VAPT is complicated since it relies on a variety of circumstances.
Among the most crucial factors are:

• VAPT Endurance
• The cost of VAPT
• Data type stored
• Requirements for compliance

VAPT ought to be conducted on a regular basis to verify that an organisations cybersecurity defence is solid. The regularity of VAPT is determined by the organisations risk tolerance, regulatory regulations, and business activities.
DIFFERENT VAPT TOOLS
VAPT toolsare a class of software used to evaluate the confidentiality of an infrastructure, network, or application. Here are a number of the best open-source tools for doing VAPT:
Wireshark
Ethereal is an internet traffic analyser and monitoring programme that shows you what traffic is flowing throughout your personal computer network. It is free to download and the most widely used network analyser on the planet. It is mostly used by network administrators and experts to diagnose communication and system performance issues, as well as monitor and filter various network protocols.
Nmap
Nmap is a network administration programme that is free and open source and is used to monitor network connections. It is used for examining large networks and aids in the auditing of hosts and services; it also helps with detecting breaches. It is used to analyse network hosts at both the packet and scan levels. Nmap is a free programme that may be downloaded.
Metasploit
Metasploit is an exploit code creation and deployment framework for a remote target system. H.D. Moore first published it as a free software project in 2003. Security researchers use Metasploit to create and validate exploit code before deploying it in the wild. It might be used to evaluate a networks security or get into a remote machine. It is also used by numerous safety specialists and hackers to test, including hacking into organisations and network devices.
CONCLUSION
Finally, VAPT is a necessary practise for organisations that rely on the Internet of Things. While it has certain disadvantages, the positive aspects of VAPT operations far exceed the disadvantages. Organisations can safeguard themselves against cyber assaults and threats by recognising possible vulnerabilities and gaps in their systems.
