In current information era, every small-scale industry, MNC's, Schools, and Colleges utilise Web Applications to promote their organizations and provide services to society. Web Applications have become a simple and vital medium for communicating with society. This leads to an increase in website utilization. Threats and cyber-attacks are increasing according to the rate of growth of Web Applications. Any organization must ensure the privacy and security of its users' data in order to maintain the company's and users' integrity. Web application vulnerabilities represent major security risks, making it critical to conduct extensive assessments and penetration testing to discover and remediate such flaws. The paper provides a complete overview of web application vulnerability assessment and penetration testing, emphasizing the need of proactive security measures in protecting sensitive data and preserving application integrity. This study aims to identify and categorize web application vulnerabilities (OWASPs) that may compromise the security of the application and result in user data breaches. The primary focus of this project is the security and privacy of user data. Integrating security practices into the software development life cycle through investigating real-world case studies and industry standards. Ultimately, our research adds to the growing body of knowledge in web application security, assisting organizations in creating resilient defenses against cyber threats.

Internet users and its usage have grown almost exponentially during last decade. Most of the web applications contain both private(sensitive) and public information in theircorresponding database that brings the security of private information on the forefront of the challenge of this domain. Cyber criminals can attempt to stealor tamperwith private information from these insecure or vulnerable web applications by exploiting. In this paper, we have analyzed different approaches of web application security used in current practices since their development such as secure coding, Web Application firewall, vulnerability assessment and penetration testing. In addition, we have also discussed various approachesand repositories which support vulnerability assessment and penetration testing processes.

Most people in the industrial world use a wide variety of web applications daily with the majority being insecure and vulnerable. This gives hackers the opportunity to steal data from the user’s web application, which may contain sensitive information. Vulnerability detection may be conducted by a rigorous penetration test. A penetration tester’s duty is to define and exploit the web applications’ vulnerabilities.This paper describes a technique for automatic vulnerable web application generation application. Firstly, the prepared web application is sent to the tool to create the vulnerable web application version. This tool does this by the injection of Cross Site Request Forgery (CSRF) and Cross Site Scripting (XSS) into the web application. Different variant vulnerabilities may be injected too, so different methods are needed, in order to exploit vulnerabilities dependent on the variant. One of the tool’s tasks is to produce web applications, which will be used to train the penetration testers.

This capstone project shows the creation and implementation of a virtual environment for the use of penetration testing. This aims to identify vulnerabilities within IT in- frastructure. With a world that is heavily reliant on digital systems, the cybersecurity threats are evolving at a rapid pace which highlights the necessary measurements needed for effective security measures.

With the increasing reliance on web applications for business and personal use, ensuring website security has become a critical concern. Cyber threats such as SQL injection, cross-site scripting (XSS), malware infections, and unauthorized access pose significant risks to websites, leading to data breaches and service disruptions. This project aims to develop a comprehensive website security scanner that systematically identifies vulnerabilities and potential security risks.The proposed system integrates automated vulnerability scanning, penetration testing techniques, and real-time monitoring to detect security loopholes. Using machine learning and heuristic-based analysis, the scanner can identify malicious scripts, outdated software versions, weak authentication mechanisms, and misconfigured security policies. The system also performs network security assessments, analyzing potential DDoS (Distributed Denial-of-Service) attack risks and firewall configurations. The scanner generates detailed security reports, providing actionable insights and recommendations for website owners and administrators to mitigate risks effectively. Designed for continuous monitoring and proactive defense, the tool enhances cybersecurity resilience against evolving threats. This project contributes to web security advancements by offering an intelligent, automated, and scalable solution for safeguarding websites from cyberattacks.

The rising of technology in the 21st century grows in a way that we never thought of before. The COVID-19 pandemic shifted many organizations in different sizes, specialties, and sectors to work online, resulting in a critical need to secure their software, applications, and web-based applications. Furthermore, Organizations that do not implement security in the Software Development Life Cycle (SDLC) process often discover that their applications suffer from security flaws and security bugs, thus exposing their applications to attacks. Applying security measures to the SDLC will ensure that applications are secure from the early planning stages until release. Penetration testing is an essential security measure and is counted as one of the best security practices applied to applications because it focuses on the technical part of application security. Each kind of application the organization uses, in-house developed applications or on-the-shelf applications, has its method for penetration testing. This paper is a systematic literature review that examines the web application security measures and the penetration testing methods and tools to detect vulnerabilities on web applications. Moreover, it gives a general view of adapting penetration testing as a security approach to the SDLC.

Every organization has implemented cybersecurity for network security. Both web applications and organizations’ network security should be free from complex vulnerabilities. It refers to the security flaws in the network or weakness in the web applications. By using the exploits available, the hacker could attack our target system to steal confidential data. So, to secure the security of networks the most common and major technique used is ethical hacking. It comprises complex levels of vulnerability assessment and performing penetration testing by using the identified exploits. In this research paper, I have demonstrated and analyzed the methodologies through which the pen tester accesses the target system, identifying exploits, attacking the target system using the identified exploit privilege escalation, and capturing the root flag to access the data. Finally, before exiting he should clear the system as before. Finally, the pen tester generates a report containing the guidelines to eliminate the security flaws and improve network security.

Internet has been dominating the world nearly a decade. Web application is known to be the most widespread platform of the internet especially when it comes to share resources, e-commerce services, education and business platforms. Since the usage of web applications are increasing dramatically, it’s becoming more vulnerable for security attacks. Each year, organizations facing many security attacks towards their web applications. Although many security practices and mitigations have been applying in web application, however there are still some security loophole issues can be found in web application. For instance, these loopholes can be referred as lack of secure coding (standards) implemented in web application, lack of formal security training approach for web developers and improper security testing for their web application. Besides, social engineering attacks also tremendously increasing each year. Many organizations were compromised through phishing attacks due to lack of awareness among users (employees). As a solution to overcome the issues, a research project will be carried out to implement a system called Nscanner to detect Structured Query Language injection (SQLi) and Cross-Site Scripting (XSS) vulnerabilities for web application. Moreover, the developer also will design a malware detection feature based on machine learning approach to detect malware found in attachments from emails in order to prevent malware phishing attacks.

With positively increasing technological inventions and their intervention in our lives, there also exist the dark side of security breaches and potential threats which negatively affects our sustainable and secure growth. Security on networks is of utmost priority and methodologies like penetration testing help us achieve frequent quality checks in place. With an ever growing population and their heavy dependence on technologies, there is an ever increasing security and data threat which immediately calls for an unprecedented and highly secure set of methods, which are practical in nature, have minimal footprint, and can be employed across platforms, throughout the interdisciplinary industries for one common goal to “achieving security on networks and mitigating and identifying threats”. In this study, we review and propose practical solutions to implement penetration testing using a controlled setup. Raspberry Pi 3b+ (portable mini-computer) was used for studying and assessing the penetrability and identify network shortcomings using assessment tools, like built-in pen-testing tool. This manuscript mainly discusses the importance and applicability of smart devices for penetration testing developing vulnerability assessment.

Web applications have become an integral part of the daily lives of millions of users. Unfortunately, web applications are also frequently targeted by attackers, and critical vulnerabilities such as cross-site scripting and SQL injection are still common. As a consequence, much effort in the past decade has been spent on mitigating web application vulnerabilities. Current techniques focus mainly on sanitization: either on automated sanitization, the detection of missing sanitizers, the correctness of sanitizers, or the correct placement of sanitizers. However, these techniques are either not able to prevent new forms of input validation vulnerabilities such as HTTP Parameter Pollution, come with large runtime overhead, lack precision, or require significant modifications to the client and/or server infrastructure. In this paper, we present IPAAS, a novel technique for preventing the exploitation of cross-site scripting and SQL injection vulnerabilities based on automated data type detection of input parameters. IPAAS automatically and transparently augments otherwise insecure web application development environments with input validators that result in significant and tangible security improvements for real systems. We implemented IPAAS for PHP and evaluated it on five real-world web applications with known cross-site scripting and SQL injection vulnerabilities. Our evaluation demonstrates that IPAAS would have prevented 83% of SQL injection vulnerabilities and 65% of cross-site scripting vulnerabilities while incurring no developer burden.

The main issues of current web application is easily hacking the user information by unauthorized person. The development of entire web application depends on scripting languages that easily displays the user authentication code to the web browser. All code must be transferred through query string parameter (URL) of the web application. This kind of application security fails when verifying it by penetration testing which is based on XSS languages. This study overcomes the security issues by developing a web application based on cross site scripting technique which the user codes are encrypted using RSA algorithm and cookies, cross domain verification based on encrypted use code. XSS vulnerabilities come in different forms and may be categorized into two varieties: reflected and stored. Reflected is on type of attack which can be performed against applications that employ a dynamic page error message to users. Stored XSS vulnerability appears when data submitted by one user is store in the application or in the back-end database. The user cookies of the web browser store only the encrypted key values. These techniques applied in Enterprise web application it support multiple organization for processing product purchase order, sales order and invoice details.
