Submit Cheat
If maintaining the state for CSRF token on the server is problematic, an alternative defense is to use the double submit cookie technique. This technique is easy to implement and is stateless. In this technique, we send a random value in both a cookie and as a request parameter, with the server verifying if the cookie value and request value match. When a user visits (even before authenticating to prevent login CSRF), the site should generate a (cryptographically strong) pseudorandom value and set it as a cookie on the user's machine separate from the session identifier. The site then requires that every transaction request includes this pseudorandom value as a hidden form value (or as a request parameter/header). If both of them match at server side, the server accepts it as legitimate request and if they don't, it would reject the request.
Submit Cheat
Adding CSRF tokens, a double submit cookie and value, an encrypted token, or other defense that involves changing the UI can frequently be complex or otherwise problematic. An alternate defense that is particularly well suited for AJAX or API endpoints is the use of a custom request header. This defense relies on the same-origin policy (SOP) restriction that only JavaScript can be used to add a custom header, and only within its origin. By default, browsers do not allow JavaScript to make cross origin requests with custom headers.
While these are a very strong CSRF defense, it can create a significant impact on the user experience. As such, they would generally only be used for security critical operations (such as password change, money transfers, etc.), alongside the other defences discussed in this cheat sheet.
The following JEE web filter provides an example reference for some of the concepts described in this cheatsheet. It implements the following stateless mitigations (OWASP CSRFGuard, cover a stateful approach).

An SFTP connection requires appropriate software, so you will need an SFTP server utility on one of the two devices in communication and a client at the other end. Most SFTP utilities provide both functions.","author":"@type":"Person","name":"Stephen Cooper","description":"Stephen Cooper has taken a close interest in online security since his thesis on Internet encryption in the early 90s.

The __RequestVerificationToken is automatically generated by ASP.NET and included as a hidden field. When the form is submitted this will be included in the form data and ASP.NET will validate it to ensure this is a legitimate request.
This paper reports on the growth of how a single market leading file sharing website has been used for contract cheating purposes. The period of growth coincides with the Covid-19 pandemic and the associated necessary increase in online teaching and assessment within education.
This paper considers how contract cheating takes place on the market leading file sharing site Chegg (2020). It makes reference to the volume of requests made and answers supplied pre and post Covid-19. The pandemic has seen the movement of teaching and assessment online, often made with little time for the revised method of provision to have been planned in advance or for academic integrity safeguards to be put into place. Where students have previously been taught face-to-face, activities such as in-person lectures, tutorials, assessments and exams have been replaced by virtual alternatives. The unsupervised nature of assessment, including exams, may mean that students have had increased temptation to cheat or may have felt that the support they would usually have available was not there.
The paper first discusses the relevant literature surrounding academic integrity, contract cheating and online exams in more detail. Online teaching and assessment are not in themselves new, even though changes to assessment due to Covid-19 may have made this more prominent. The Chegg file sharing site is further discussed, with reference to how this can be used for contract cheating purposes. The paper provides a quantitative analysis of how Chegg is used for contract cheating within a selection of Science, Technology, Engineering and Mathematics (STEM) subjects, offering an analysis over a two-year period with reference to pre and post Covid-19 provision. The paper concludes by recommending that the sector works to address contract cheating through file sharing sites particularly as this relates to Covid-19. 041b061a72
