Study Notes
Web Browsers and Web Technology
- Web browsers are applications that display various types of content on the Internet, including text, images, animations, and videos.
- The World Wide Web (WWW) relies on technologies such as Web browsers, Hypertext Markup Language (HTML), and Hypertext Transfer Protocol (HTTP).
Server and Client Communication
- Web servers process network requests and deliver files to create web pages using HTTP.
- Servers operate in a "passive open" state, waiting for client connections, while clients initiate connections through TCP synchronization messages (SYN).
- A reliable connection is established via a three-way handshake involving SYN, SYN-ACK, and ACK messages.
- Retransmission ensures reliability by resending lost data packets within a defined timeout period, driven by ACK value verification.
Cybersecurity and IP Addresses
- IP addresses uniquely identify devices connected to the Internet, facilitating data location and retrieval.
- Public IP addresses identify external devices connecting to the ISP, typically the router for internet access.
- Private IP addresses are assigned within a local network and managed by routers for devices connected to it.
Web Development Technologies
- HTML structures and displays content on web pages.
- CSS enhances visual appearance by adding colors and styles.
- JavaScript enables interactive features and animations on web pages.
- Backend technologies and database systems support server-side functionality and data management.
Concepts of Cyberspace
- Cyberspace exists wherever the Internet is utilized, including online gaming platforms, creating digital realms without physical counterparts.
Cybersecurity Layers
- A layered cybersecurity approach involves protecting mission-critical assets against malicious threats.
- URL (Uniform Resource Locator) consists of various parts defining the location and retrieval mechanism for web resources.
Web Browsers and Servers
- Popular web browsers: Chrome, Internet Explorer, Firefox, Apple Safari, Opera.
- Web hosting provides services for individuals and businesses to store and access web pages on the Internet.
Internet vs. Web
- The Internet is a vast network of interconnected computers enabling global communication and resource access.
Data Management
- Data management encompasses collecting, storing, utilizing, and overseeing data as an enterprise asset for secure and efficient usage.
- Benefits of data governance include improved decision-making, cost control, regulatory compliance, enhanced trust, risk management, and data accessibility.
Cybersecurity Challenges in 2023
- Ransomware has evolved into a significant threat, utilizing data encryption for extortion purposes while prompting increased security measures to combat it.
