web applications add more dynamism to websites and better functionality to end users, they also increase the number of vulnerabilities across websites, web apps, and web services. This increases opportunities for cyber attacks as each application has its own development lifecycle. Whereas cyber crime used to target only the most critical flagship applications, today’s cyber attacks often exploit lesser applications. Less visible applications are often less secure, providing entryways into the security infrastructure or backend corporate databases. A large number of breaches (approximately 40%) originate in attacks on the application layer.
Unlike a particular toolset, solution, or process, web application security is most effectively understood as a strategic initiative and set of best practices. Threat landscapes constantly change and evolve, which means that security programs need to continually integrate with the software development lifecycle (SDLC) and monitor websites and applications throughout their operations.
