Introduction to secure web

The implementation of web-based security features (or features that are used to maintain a secure state of access) to access information is rapidly growing, day by day. With ever-growing web-based technologies, websites and web applications deploy secure mechanisms that are basic or highly sophisticated.

Secure web-enabled content is often challenging from a crawling and scraping perspective. In this section, you will be introduced to a few basic security-based concepts. We will explore these concepts, along with their implementation, in the upcoming sections.

The following sections will talk about a few security-enabled concepts or concepts that are vulnerable to security. These concepts can be implemented independently and collaboratively in websites using a number of underlying tools or measures.
