Obfuscation is when easy-to-understand source code is converted into a hard to understand and confusing code that still operates as intended.

Web applications are often deeply integrated and widely accessed within companies, defying the neatly defined security borders of the standalone systems targeted by the OMB. Neglecting web application security therefore neglects a significant area of cyber risk for companies.
