1.To defeat XSS attacks, a developer decides to implement filtering on the browser side. Basically, the developer plans to add JavaScript code on each page, so before data are sent to the server, it filters out any JavaScript code contained inside the data. Let’s assume that the filtering logic can be made perfect. Can this approach prevent XSS attacks? 2.What are the differences between XSS and CSRF attacks? 3.Can the secret token countermeasure be used to defeat XSS attacks? 4.Can the same-site cookie countermeasure for CSRF attacks be used to defeat XSS at- tacks? 5.To filter out JavaScript code from user input, can we just look for script tags, and remove them? If you can modify browser’s behavior, what would you add to browser, so you can help reduce the risks of XSS attacks?

25. Is it possible that when a user clicks on a link with Netscape, a particular helper is started, but clicking on the same link in Internet Explorer causes a completely different helper to be started, even though the MIME type returned in both cases is identical? Explain your answer.............
1. The fundamental cause of XSS vulnerabilities is that HTML allows JavaScript code to be mixed with data. From the security perspective, mixing code with data is very dan- gerous. XSS gives us an example. Please provide two other examples that can be used to demonstrate that mixing code with data is bad for security. 2. Why is the CSP (Content Security Policy) effective in defeating the Cross-Site Scripting attack? What is the downside of this approach? 3.Can CSP (Content Security Policy) be used to defeat CSRF attacks? Why or why not? 4.
For the RogueRaticate malware, please write a short paragraph based on the given background and website info: The RogueRaticate campaign, otherwise known as FakeSG, was spotted by Proofpoint in May 2023 but its activity may date back to November 2022. It's the first major fake-browser-update campaign to emerge since SocGholish and typically leads to the NetSupport RAT being installed on the victim's machine. A month later in June, the first activity from the ZPHP campaign, also known as SmartApeSG, was spotted and finally made public in August by Trellix. Like RogueRaticate, ZPHP also most often leads to the installation of NetSupport RAT, which has been infecting machines since around 2017, according to SentinelOne. The most recent of the four campaigns is ClearFake, which was first spotted in July and made public in August by researcher Randy McEoin. Proofpoint characterized ClearFake as a campaign that drops infostealer malware and is able to tailor lures not just by the user's…
What is the common idea behind the X-Frame-Options and CSP mechanisms? Whyis it effective in defeating the Clickjacking attack?
1.Please describe two common approaches used by clickjacking attacks? 2. Please construct two iframes, such that one of the iframes seems to be part of the page inanother iframe. Please then describe how this setup can be used in clickjacking attacks. 3.What is the common idea behind the X-Frame-Options and CSP mechanisms? Whyis it effective in defeating the Clickjacking attack? 4.When a host page puts a page inside an iframe, can the host page access the contentinside the iframed page? 5.The following JavaScript code displays content inside a page. The content comes froman untrusted place. If the content, which is supposed to be data only, contains JavaScriptcode, can the code be executed? Why? const iframe = document.createElement("iframe");iframe.srcdoc = content;iframe.sandbox = "";document.body.appendChild(iframe);
The chapter includes a demonstration of how to decrypt TLS using the Chrome web browser. Whether you use a different web browser, such Firefox or Safari, check to see if it saves SSL key records in a manner that is analogous to Chrome's. Your findings should be reported, along with an explanation of why a forensic investigator could find the material relevant.
Explore the security considerations in web development, including common vulnerabilities like Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF).
Explore the security challenges and best practices for securing APIs in modern web applications, covering topics like authentication, authorization, and protection against common vulnerabilities.
The chapter demonstrates how to decrypt TLS in the Chrome web browser. Try using an other browser, such Firefox or Safari, to check whether it saves SSL key records in the same way as Chrome does. Send in your findings and provide a justification for why a forensics investigator would find them helpful.
