    Study Notes

    Web Application Security Fundamentals

    • Web application security involves understanding the evolution of web applications, common web application functions, and common web application vulnerabilities.

    The Internet and WWW

    • The Internet is a system of interconnected networks that enables global communication and access to data resources.
    • The Internet is managed by organizations that create global protocols, such as the Internet Assigned Numbers Authority (IANA).
    • The World Wide Web (WWW) is a collection of information that can be accessed via the Internet.
    • WWW is a service built on top of the Internet's infrastructure.
    • The Internet provides other services besides WWW.

    Client-Server Model

    • The client-server model is a distributed application structure that partitions tasks or workloads between servers and clients.
    • Every machine on the Internet is either a server or a client.
    • Servers provide services to other machines, while clients utilize these services.
    • The client-server model uses a request-response mechanism.

    The WWW

    • The WWW is a distributed system made up of both client and server software.
    • Web browsers are client programs that request services from Web servers.
    • Users can interfere with data transmitted between the client and server, and can send requests in any sequence.

    The OWASP Foundation

    • The Open Web Application Security Project (OWASP) provides free and open resources.
    • The OWASP Foundation is a non-profit organization.
    • The OWASP Top 10 - 2017 is a published result of recent research based on comprehensive data.

    OWASP Top 10

    • The OWASP Top 10 - 2017 lists the top 10 web application security risks, including:
      • SQL injection
      • Broken Authentication
      • Sensitive Data Exposure
      • XML External Entities (XXE)
      • Insecure Direct Object References
      • Security Misconfiguration
      • Cross-Site Scripting (XSS)
      • Insecure Deserialization
      • Using Components with Known Vulnerabilities
      • Insufficient Logging and Monitoring

    Web Applications

    • A Web application (Web app) is an application program stored on a remote server and delivered over the Internet through a browser interface.
    • Web applications are mostly dynamic pages and provide two-way communication to interact with users.
    • Encryption and authentication are essential in web applications.
    • Web applications have evolved from passive viewing to dynamic, interactive pages with encryption and authentication.

    Popularity of Web Apps

    • Web applications are popular due to the lightweight and connectionless protocol (HTTP).
    • Every user has a browser installed on their computer and mobile device.
    • Browsers are highly functional, enabling rich and satisfying user interfaces.
    • Core technologies and languages used to develop web applications are relatively simple.

    Enterprise Web Applications

    • Enterprise web applications are large-scale software solutions designed to meet the complex needs of organizations and businesses.
    • These applications are accessed through web browsers and provide a range of functionalities to support various business processes.
    • Examples of enterprise web applications include CRM, ERP, HRMS, and project management tools.
    • Characteristics of enterprise web applications include scalability, with the ability to handle a large number of users and data.
