What is a VPN (Virtual Private Network)?
A Virtual Private Network (VPN) creates an encrypted tunnel between a user's device and a remote server, protecting internet traffic from interception and masking the user's IP address for enhanced privacy and security.
What is a WAF (Web Application Firewall)?
A Web Application Firewall (WAF) is a security solution that monitors, filters, and blocks HTTP/HTTPS traffic between a web application and the internet to protect against application-layer attacks.
What is a web crawler?
A web crawler is an automated bot that systematically browses the internet to discover, index, and catalog web pages, primarily used by search engines to build and update their search indexes.
What is a zero-day exploit?
A zero-day exploit is an attack that targets a previously unknown software vulnerability for which no patch or fix exists, giving defenders zero days to prepare or respond.
What is a Zero-Day Exploit?
A zero-day exploit is an attack that targets a previously unknown software vulnerability for which no patch or fix exists, giving developers zero days to address the flaw before it is actively used in attacks.
What is BGP hijacking?
BGP hijacking is an attack on the internet's routing infrastructure in which an attacker maliciously announces ownership of IP address blocks they do not control, redirecting internet traffic through their network.
What is blackhole routing?
Blackhole routing is a network defence technique where traffic destined for a specific IP address or range is silently dropped by routing it to a null interface, commonly used as an emergency response to DDoS attacks.
What is bot traffic?
Bot traffic refers to any non-human visitors to a website, including both beneficial bots like search engine crawlers and harmful bots that scrape content, attempt attacks, or inflate analytics data.
What is buffer overflow?
A buffer overflow is a software vulnerability that occurs when a program writes more data to a buffer than it can hold, potentially allowing attackers to overwrite adjacent memory and execute arbitrary code.
What is click fraud?
Click fraud is the practice of using bots or automated scripts to generate fake clicks on pay-per-click advertisements, costing advertisers money without delivering genuine user engagement.
