Question

CAPTCHAs, rate limiting, and blacklisting systems or networks that are gathering data are all common ___________ techniques.

Answer 1

CAPTCHAs, rate limiting, and blacklisting are security techniques used to protect online services from automated abuse and unauthorized data gathering.

Step-by-step explanation:

CAPTCHAs, rate limiting, and blacklisting systems or networks that are gathering data are all common security techniques. These are methods used to protect websites and online services from abuse, such as brute force attacks, automated bot traffic, and data scraping. CAPTCHAs help in verifying that a user is human, rate limiting controls the number of requests a user can make in a certain timeframe, and blacklisting allows blocking of suspicious IP addresses or networks from accessing a service.

Answer 2

CAPTCHAs, rate limiting, and blacklisting systems or networks that are gathering data are all common anti-scraping techniques.

Step-by-step explanation:

To deter or prevent web scraping activities, website owners and administrators deploy various anti-scraping techniques. CAPTCHAs (Completely Automated Public Turing test to tell Computers and Humans Apart) are challenges designed to distinguish between automated bots and human users. Rate limiting involves restricting the number of requests a user can make within a specific time frame, preventing rapid and excessive data gathering. Blacklisting systems or networks involves identifying and blocking IP addresses or entire networks known for engaging in scraping activities.

These techniques collectively form a defense mechanism against unwanted data harvesting, safeguarding the integrity and performance of websites and online platforms. By implementing such measures, website owners can protect their content, maintain server resources, and ensure a fair and secure online environment.
