Content Security Policy (CSP) - HTTP | MDN
10/15/2020 Content Security Policy (CSP) - HTTP | MDN Sign in English ▼ Content Security Policy (CSP) Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement to distribution of malware. CSP is designed to be fully backward compatible (except CSP version 2 where there are some explicitly-mentioned inconsistencies in backward compatibility; more details here section 1.1). Browsers that don't support it still work with servers that implement it, and vice-versa: browsers that don't support CSP simply ignore it, functioning as usual, defaulting to the standard same- origin policy for web content. If the site doesn't offer the CSP header, browsers likewise use the standard same-origin policy. To enable CSP, you need to configure your web server to return the Content-Security- Policy HTTP header. (Sometimes you may see mentions of the X-Content-Security- Policy header, but that's an older version and you don't need to specify it anymore.) Alternatively, the <meta> element can be used to configure a policy, for example: <meta http-equiv="Content-Security-Policy" content="default-src 'self'; img- src https://*; child-src 'none';"> Threats Mitigating cross site scripting A primary goal of CSP is to mitigate and report XSS attacks. XSS attacks exploit the browser's trust of the content received from the server. Malicious scripts are executed by the victim's browser because the browser trusts the source of the content, even when it's not coming from where it seems to be coming from. -

Internet Privacy Implications Research and Draft
Internet Privacy Implications A Major Qualifying Project Worcester Polytechnic Institute Submitted to the Faculty of the Worcester Polytechnic Institute in partial fulfillment of the requirements for the Degree of Bachelor of Science. Submitted By: Goncharova, Masha Harnois, Jeffrey Advisors: Wills, Craig PhD Doyle, James PhD May 6, 2021 Abstract Our research focused on understanding the effectiveness of browsers, extensions, mobile applications, and search engines and their protection of user privacy. We ran test cases on the top 100 Alexa sites, using a Fiddler proxy to capture traffic, with certain configurations of tools mentioned to see which ones were efficient in blocking user tracking technologies. We found that Brave and Firefox in Strict mode are the best browsers in terms of tradeoff between percent of websites with degradation versus percent trackers remaining. uBlock Origin, Ghostery and Privacy Badger are the best browser extensions in terms of the same tradeoff. Based on our results, we created a recommendation system using a survey approach. We suggest a combination of tools that are personalized to users based on their reported privacy preferences and desire to switch their current browsing setup. In order to better understand users’ views on privacy, we additionally showed participants their own data Google has synthesized about them to evaluate if that would change their responses. A ceiling effect appeared in our responses, indicating that no matter the condition, all our participants indicated a willingness to switch to the tools that we were recommending. 1 Table of Contents Abstract 1 Table of Contents 2 List of Tables 6 List of Figures 7 Double Major Note 9 1. -

This lack of control leaves applications open to attacks such as Cross Site Scripting, data leaks and content injection. Content Security Policy, CSP, was proposed and implemented as a way for applications to specify restrictions on how clients use content. However elaborating and maintaining a security policy can be a slow and error-prone process, especially for large websites. In this paper we propose a system to automate the policy generation process, and study its performance with an analysis of websites. The generated CSPs restrict client-server information flows of an application, using validated historical data. We reach a 0.81% miss rate, with an average of 7 directives for a given website. We consider the case where one externally maintains a security policy for a website which does not provide its own yet. iv Table of Contents List of Tables ::::::::::::::::::::::::::::::::::::::::::: vi List of Figures :::::::::::::::::::::::::::::::::::::::::: vii Acknowledgments :::::::::::::::::::::::::::::::::::::::: viii Chapter 1. -
