The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others. Source: https://www.owasp.org/index.php/Denial_of_Service
Allocating objects or timers with user-controlled sizes or durations can cause resource exhaustion.
Use of vulnerable components will introduce weaknesses into the application. Components with published vulnerabilities will allow easy exploitation as resources will often be available to automate the process.
Denial of Service on the main website for The OWASP Foundation. OWASP is a nonprofit foundation that works to improve the security of software.
