  • A Web Server Called Liso
    15-441/641: Computer Networks Project 1: A Web Server Called Liso TAs: Mingran Yang ([email protected]) Alex Bainbridge ([email protected]) September 29, 2019 1 Introduction In this class you wil learn about Computer Networks, from bits on a wire or radio (`the bottom') all the way up to the design of applications that run over networks (`the top)'. In this project, you will start from the top with an application we are all familiar with: a web server. You will use the Berkeley Sockets API to write a web server using a subset of the HyperText Transport Protocol (HTTP) 1:1 |RFC 2616 [2]. Your web server will also implement HyperText Transport Protocol Secure (HTTPS) via Transport Layer Security (TLS) as described in RFC 2818 [3]. Students enrolled under the 15-641 course number will implement the Common Gateway Interface (CGI) as described in RFC 3875 [4]. Reading an RFC is quite different from reading a news article, mystery novel, or even technical paper. Appendix B.2 has some tips read and use and RFC efficiently. RFCs are one of many ways the Internet declares `standards:' agreed upon algorithms, wire formats, and protocols for interoperability between different implementations of systems on a network. Without standards, software from one company would not be able to talk to software from another company and we would not have things like e-mail, the Web, or even the ability to route traffic between different companies or countries. Because your web server is compatible with these standards, you will, by the end of this project, be able to browse the content on your web server using standard browser like Chrome or Firefox.

    Secure Session Management Fariha Nazmul Kongens Lyngby 2011 IMM-M.Sc.-2011-45 Technical University of Denmark Informatics and Mathematical Modelling Building 321, DK-2800 Kongens Lyngby, Denmark Phone +45 45253351, Fax +45 45882673 [email protected] www.imm.dtu.dk IMM-M.Sc.-2011-45 Preface The stateless behavior of HTTP requires web application developers to use sepa- rate stateful or stateless mechanisms with HTTP for maintaining state and user specific session information. The task of maintaining user based state informa- tion in a logical connection between the server and the user device is known as session. Web session management is a method that allows the web server to exchange state information to recognize and track every user connection. A critical issue in web security is the ability to bind user authentication and access control to unique sessions. Vulnerabilities in the session management pro- cess can cause serious damage since the sessions generally maintain important and sensitive data of the web based systems. The aim of this Master thesis is to concentrate on the security of session man- agement in a single server environment. The thesis focuses on analyzing the important aspects of a secure session management mechanism that are the abil- ity to bind an incoming request to the session it belongs to, to determine where and how the session state can be stored and to find out measures to protect the session handling mechanisms from security attacks. In addition, this the- sis shows the basic steps of implementing a session with PHP and discusses the implications of manipulating some of the session management configuration options on the security level of the application.

  • Mitigating CSRF Attacks on Oauth 2.0 and Openid Connect
    Mitigating CSRF attacks on OAuth 2.0 and OpenID Connect Wanpeng Li1, Chris J Mitchell2, and Thomas Chen1 1 Department of Electrical & Electronic Engineering City, University of London, UK fWanpeng.Li, [email protected] 2 Information Security Group Royal Holloway, University of London, UK [email protected] Abstract. Many millions of users routinely use their Google, Face- book and Microsoft accounts to log in to websites supporting OAuth 2.0 and/or OpenID Connect-based single sign on. The security of OAuth 2.0 and OpenID Connect is therefore of critical importance, and it has been widely examined both in theory and in practice. Unfortunately, as these studies have shown, real-world implementations of both schemes are of- ten vulnerable to attack, and in particular to cross-site request forgery (CSRF) attacks. In this paper we propose a new technique which can be used to mitigate CSRF attacks against both OAuth 2.0 and OpenID Connect. 1 Introduction Since the OAuth 2.0 authorisation framework was published at the end of 2012 [11], it has been adopted by a large number of websites worldwide as a means of providing single sign-on (SSO) services. By using OAuth 2.0, websites can reduce the burden of password management for their users, as well as saving users the inconvenience of re-entering attributes that are instead stored by identity providers and provided to relying parties as required. There is a correspondingly rich infrastructure of identity providers (IdPs) providing identity services using OAuth 2.0. This is demonstrated by the fact that some Relying Parties (RPs), such as the website USATODAY3, support as many as six different IdPs | see Fig.
