Security assessment of web applications and networks in the form of penetration testing - modelling actions of a potential attacker (hacker) with the goal to identify security weaknesses and flaws in the target system or network. Depending on a given scope, a penetration test can take between 1 and 10 man-days (each man-day = 8 working hours). A scope is defined together with a client prior an assessment. Delivered result: A penetration testing report containing management summary, summary of identified security weaknesses, detailed technical description of all identified security vulnerabilities along with the steps to reproduce and recommendations on fixing them.
