This document proposes a client server mutual authentication technique to prevent CSRF (cross-site request forgery) attacks. It separates the identification and authentication steps. When a user logs in, the server provides an encoded authentication token to the user in the form of an image. To complete sensitive requests, the server asks the user to select the correct token from multiple images to verify their identity. Encoding the tokens with base64 encoding improves security. The technique was tested and found to prevent CSRF attacks made through POST or GET requests using JavaScript or HTML tags by requiring the valid token for each request. This provides better protection against CSRF attacks compared to existing solutions.
CSRF Attacks and its Defence using Middlewareijtsrd
A common solution to the issue of CSRF vulnerability is to restrict malicious requests from reaching the core of the application, where all the data and business logic is present. But the most challenging part is to identify when a request is malicious and when is it healthy. Implementing a simple solution would lead to more vulnerabilities and implementing too strict a solution would lead to breakages where projects depend on cross site requests like third party authentication and payment gateways etc. The solution being proposed in this paper constitutes the design and implementation of a request filtering mechanism that can precisely distinguish between malicious and healthy requests, and automatically decide to restrict them or allow them to get further deep into the system. This paper briefly explains what a Cross Site Request Forgery attack is, and then goes into a step by step explanation on the prevention of CSRF attacks using a middleware. The proposed system is very strict in filtering out HTTP requests but also has an option to exempt certain cross site requests based on their domain or URL, with which payment hooks and other third party authentication calls can be exempted from the CSRF middleware.

Cross-site request forgery (CSRF) is a type of attack that forces end users to execute unwanted actions on a web application in which they are currently authenticated. It is currently the fifth-most-risky attack in the OWASP Top 10.
“If you have not taken specific steps to mitigate the risks of CSRF attacks, your applications are most likely vulnerable,” says expert Chris Schiflett.
This presentation provides Java professionals an anatomy of CSRF in Java web applications and answers how to avoid this in new Java applications with a secure design approach and also discusses how to remediate this issue in business-critical legacy Java web applications without redesigning them.
This presentation includes a demo of the vulnerability and the remediation approach.

Web Vulnerabilities And Exploitation - Compromising The WebZero Science Lab
One of the main problems of all big companies is how their applications are secured from cyber attacks. New types of vulnerabilities and attack vectors are being developed every day, therefore they pose a potential threat to all applications that rely on some kind of web technology. This document explains the most common and most dangerous web attacks as well as techniques how to secure your infrastructure from being compromised. We focus on SQL injections, XSS, CSRF, RFI/LFI and Server Side Includes. We discuss the attack vectors of web vulnerabilities and exploitation schemas. However, regardless of the security measures taken and defenses being deployed, there will always be a way in. Nevertheless, security analysis provide a valuable insight that can grant the advantage over said attackers and allow us to stay one step ahead.
Routine Detection Of Web Application Defence FlawsIJTET Journal
Abstract— The detection process for security vulnerabilities in ASP.NET websites / web applications is a complex one, most of the code is written by somebody else and there is no documentation to determine the purpose of source code. The characteristic of source code defects generates major web application vulnerabilities. The typical software faults that are behind of web application vulnerabilities, taking into different programming languages. To analyze their ability to prevent security vulnerabilities ASP.NET which is part of .NET framework that separate the HTML code from the programming code in two files, aspx file and another for the programming code. It depends on the compiled language (Visual Basic VB, C sharp C#, Java Script). Visual Basic and C# are the most common languages using with ASP.NET files, and these two compiled languages are in the construction of our proposed algorithm in addition to aspx files. The hacker can inject his malicious as a input or script that can destroy the database or steal website files. By using scanning tool the fault detection process can be done. The scanning process inspects three types of files (aspx, VB and C#). then the software faults are identified. By using fault recovery process the prepared replacement statement technique is used to detect the vulnerabilities and recover it with high efficiency and it provides suggestion then the report is generated then it will help to improve the overall security of the system.

Automated Detection of Session Fixation VulnerabilitiesYuji Kosuga
Session fixation is a technique for obtaining the visitor's session identifier (SID) by forcing the visitor to use the SID supplied by the attacker. The attacker who obtains the victim's SID can masquerade as the visitor. In this paper, we propose a technique to automatically detect session fixation vulnerabilities in web applications. Our technique uses attack simulator that executes a real session fixation attack and check whether it is successful or not. In the experiment, our system successfully detected vulnerabilities in our original test cases and in a real world web application.

Study of Cross-Site Scripting Attacks and Their CountermeasuresEditor IJCATR
In present-day time, most of the associations are making use of web services for improved services to their
clients. With the upturn in count of web users, there is a considerable hike in the web attacks. Thus, security becomes
the dominant matter in web applications. The disparate kind of vulnerabilities resulted in the disparate types of attacks.
The attackers may take benefit of these vulnerabilities and can misuse the data in the database. Study indicates that
more than 80% of the web applications are vulnerable to cross-site scripting (XSS) attacks. XSS is one of the fatal
attacks & it has been practiced over the maximum number of well-known search engines and social sites. In this paper,
we have considered XSS attacks, its types and different methods employed to resist these attacks with their
corresponding limitations. Additionally, we have discussed the proposed approach for countering XSS attack and how
this approach is superior to others.
Recent hacks of major international and regional banks have occurred due to exploits from the following vulnerabilities:
1. Cross-Site Scripting (XSS) vulnerability using redirects
2. Local File Inclusion (LFI) vulnerability
3. Cross-Site Request Forgery (CSRF) vulnerability
Analysis of XSS attack Mitigation techniques based on Platforms and Browserscscpconf
In the recent years, everything is in web. It may be Organization’s administration software,
Custom ERP application, Employee portals or Real estate portals. The Social networking sites
like Face book, Twitter, MySpace which is a web application is been used by millions of users
around the world. So web applications have become very popular among users. Hence they are
observed and may be exploited by hackers. Researchers and industry experts state that the
Cross-site Scripting (XSS) is the one of the top most vulnerabilities in the web application. The
cross-site scripting has become a common vulnerability of many web sites and web
applications. XSS consists in the exploitation of input validation flaws, with the purpose of
injecting arbitrary script code which is later executed at the web browser of the victim.
According to OSWAP, Cross-site scripting attacks on web applications have experienced an
important rise in recent year. This demands an efficient approach on the server side to protect
the users of the application as the reason for the vulnerability primarily lies on the server side.
The actual exploitation is within the victim’s web browser on the client-side. Therefore, an
operator of a web application has only very limited evidence of XSS issues. However, there are
many solutions for this vulnerability. But such techniques may degrade the performance of the
system. In such scenarios challenge is to decide which method, platform, browser and
middleware can be used to overcome the vulnerabilities, with reasonable performance over
head to the system. Inspired by this problem, we present performance comparison of two mitigation techniques for Cross-site Scripting (XSS) at the server side based on the parameters like application’s platform, middleware technology and browser used by the end user. We implemented Mitigation parsing technique using database and replace technique in different platforms, middleware and checked its performance. We calculated the time taken by different browsers to render the pages using two techniques under different platform and middleware. In this paper we proposed the best combination of development platform, browser and the middleware for the two mitigation technique with respect to developer and end users.
Tracing out Cross Site Scripting Vulnerabilities in Modern ScriptsEswar Publications
Web Technologies were primarily designed to cater the need of ubiquitousness. The security concern has been overlooked and such overlooks resulted in vulnerabilities. These vulnerabilities are being highly exploited by hackers in various ways to compromise security. When vulnerability is blocked, the attacker traces out a different mechanism to exploit it. Cross site scripting (XSS) attack is also an exploitation of one of the vulnerabilities existing in the web applications. This paper traces out the vulnerability in functions and attributes of modern scripts to carry out cross site scripting attack and suggests preventive measures.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
