I have written one article that got published in Hakin9 Magazine's July Issue. This article is about different kind of Access Control mechanisms and issues with them in Web Applications. Access Control, as the name suggests, is the mechanism of determining privileges of different users to access the contents of an application. It can also manage fine-grained read and write permissions on the files owned by a particular user. In other words, access control decides who has the authorization to use files, manipulate their contents, or visit a website. In the case of web applications, access control mechanisms allow different users different levels of access to web pages and functions. Want to read more?
