X.509

X.509 is a standard that defines the format for public key certificates. These digital certificates authenticate the identity of individuals, systems and services on the Internet.

XSS (Cross-Site Scripting)

Cross-Site Scripting (XSS) is a type of security vulnerability typically found in web applications. XSS attacks enable attackers to inject malicious scripts into web pages viewed by other users, potentially leading to unauthorized access or data theft.

XSRF CSRF (Cross-Site Request Forgery)

Cross-Site Request Forgery (XSRF or CSRF) is an attack vector that tricks the victim into executing unwanted actions on a web application in which they're authenticated. A successful CSRF exploit can lead to potential unauthorized changes such as email address change, password update, etc.

XDR (Extended Detection and Response)

Extended Detection and Response (XDR) is an integrated set of security tools that coordinate threat detection and response. XDR collects and automatically correlates data across multiple security layers – email, endpoint, server, cloud workloads, and network – so threats can be detected faster and security analysts can improve investigation and response times.
