Study Notes

Web Services

Provide interoperable machine-to-machine interaction over a network
Represent business or data-tier components used by web applications to receive information
Are connected using Service Oriented Architecture (SOA)
Web applications connect with users while services interact with other services
Languages for Secure Web Service Development:
- Do not include sensitive data in user-viewable source code
- Assemblies supporting untrusted callers should not expose objects from assemblies that do not allow untrusted callers
- Allow untrusted callers only after careful code review and security precautions
- Disable tracing, debugging, and testing-related functions before deployment
- Avoid verbose error information to the user

Markup Languages

Modern systems for annotating documents in a way that is syntactically distinguishable from the text
Categories: Presentational, Procedural, Descriptive
Common web languages: HyperText Markup Language (HTML) and Extensible Markup Language (XML)

HTML

Markup language for creating web page documents
Defines structure and layout using tags and attributes
Contains JavaScript for web page interactivity

XML

Used to express content within SOAP messages
Basis for security technologies used by Web services
Designed for extensibility and combination
Offers integrity, confidentiality, and other security benefits to XML documents
Risks posed by XML are not unique and can appear in other technologies
Risks are more severe for XML due to its expressiveness, flexibility, and power

Style Sheets

Separate presentation and content in web design
Define the look and formatting of documents written in HTML or XML
Determine how elements are displayed on a web page (layout, colors, fonts, etc.)

Client Side Scripting Languages

Executed by the user's web browser
Change static content to dynamic content based on user interaction
Examples: AJAX, DOM, ActionScript, JavaScript, VBScript

Server Side Scripting Languages

Executed by the Web Server when a document is requested
Produce output in a format understandable by Web Browsers (HTML)
User cannot see the script's source code
Require language interpreters on the server and produce consistent output regardless of the client's system
Examples: ASP, ASP.NET, ColdFusion, JSP, Perl, PHP, Python, Ruby

Sandboxed Languages

Provide an independent sandbox environment for application creation
Controlled and restricted setup for executing programs or scripts
