Web applications are the distributed platform used for information sharing and services over Internet today. They are increasingly used for the financial, government, healthcare and many critical services. Modern web applications frequently implements the complex structure requires for user to perform actions in given order. The popularity adds value to these applications, which attracts attackers towards them. The attackers are well known about the valuable information accessible through the web application, which leads to serious security attacks on web applications. In this paper we survey the state of the art in web application security; first we explain working of web application and focus on the challenges for building secure web application. We organized the existing security vulnerabilities into the security properties that web application should preserved, discussed the root cause of these vulnerabilities and their corresponding preventive measures. Next we focus on the mal... Show
Web application security has become real concern due to increase in attacks and data breaches. As Application becomes critical, complex and connected, the difficulty of achieving application security increases exponentially. Also there are tools and techniques to detect such attacks, threat and vulnerabilities that exist in application which developer prevent and mitigate the risk associated to it. This paper evaluates various web application attack detection mechanisms and how resistant they are against various attacking techniques. Such an evaluation is important for not only measuring the available attack defense against web application attacks but also identifying gaps to build effective solutions for different defense techniques on web application and use it for study. Based on the research, the limitations of these application attack detection techniques are identified and remedies proposed for improving the current state attack detection on web applications. Web applications have become critical part of business. They hold a treasure trove of data behind their front ends. Now-adays attackers are well aware of the valuable information accessible through web applications, so website security has become a major problem today. The number of vulnerabilities have multiplied in recent years. Vulnerabilities like cross site scripting(XSS),sql injection and cross site request forgery(CSRF) has emerged as a major threat to web applications. So, in order to protect web applications from these modern threats, at first vulnerability assessment should be carried out from time to time and also some preventive techniques should be followed to prevent these threats. The motivation of this paper is to promote the use of automated tools for vulnerability assessment and to follow preventive techniques in order to make web applications secure. 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. The Internet, and in particular the World Wide Web, have become one of the most common communication mediums in the World. Millions of users connect everyday to different web-based applications to search for information, exchange messages, interact with each other, conduct business, pay taxes, perform financial operations and many more. Some of these critical web-based services are targeted by several malicious users intending to exploit possible weaknesses and vulnerabilities, which could cause not only the ... Web Applications are sensitive to information security threats due to the adequate information it obtains from the users. Retaining data through web applications is the most effective thing in this day and age. Wrongly received data can be utilized to exploit a business which can be devastating, both in financial and reputational deterioration. The use of online transactions through web-based applications has resulted in numerous vulnerabilities that have been systemically analyzed by the Open Web Application Security Project (OWASP). So, it is required to raise the attention of newly developed web applications and developers. This work analysis the appropriate content about sixteen of the top web application’s vulnerabilities, i.e., Persistent cross-site scripting, Blind SQL injection, Session hijacking, Vulnerability scanning tools, DOT.NET deserialization, Bypassing REGEX restrictions, Magic hashes, Bypassing XSS Length Limitations, DOM-based cross-site scripting, Server-side template injection, Remote Code Execution, File upload limits and file extension filters, XML External Entity (XXE) Injection, Data Exfiltration, PHP programmer juggles with sloppy comparisons and PHP/CF type juggling with loose comparisons. The review has been performed for significant vulnerabilities. Also, analysis the web attacks mechanism as vulnerabilities. This research shows the impact of vulnerabilities as findings for Web applications. One of the primary objectives of this analysis is to discuss mitigation techniques- provide specific solutions to identify and defend multiple vulnerabilities. Therefore, application developers can increase awareness and investigate fundamental ways to improve the security of existing web applications Which role based access control helps prevent this OWASP Top 10 weakness?Final answer: Role-Based Access Control (RBAC) helps prevent the OWASP Top 10 weakness 'Failure to restrict URL Access' by defining user access based on roles. Explanation: Role-Based Access Control (RBAC) helps prevent the OWASP Top 10 weakness known as Failure to restrict URL Access. Which one of the OWASP Top 10 application security risks would be occur when untrusted data is sent to an interpreter as part of a command or query?1. Injection. Description: Injection flaws occur when untrusted data is sent to an interpreter as part of a command or query. Attackers can manipulate this input to execute unintended commands or access unauthorized data. Is the OWASP Top 10 list comprehensive enough for writing secure code?All of the listed weakness in OWASP Top 10 are included within the National Vulnerability Database. But this also means that the OWASP Top 10 list is not comprehensive enough, and developers should be aware of issues that may not be included within there. What is OWASP Top 10 how it helps in increasing web security?The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications. Globally recognized by developers as the first step towards more secure coding. |
