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.
