Understand Application Security: Numerous successful attacks on well-known web applications on a weekly basis should be reason enough to study the background of "Web Application Security" of custom-made or self-developed applications.

Computer systems are ubiquitous and part of our working and private everyday life. For companies it is increasingly complex and difficult to keep up their IT security with the current technical progress. Large enterprises establish security processes which are created according to industry standards (e.g., ISO 27001). These processes are very complex and can only be implemented by teams of security experts. Constant quality assurance, maintenance and adaptation also belong to an IT security process.

It does not matter if a company develops products or runs an online shop, IT security is a characteristic feature. Security incidents, which maybe even reach public uncontrolled, do not only damage the business image but may also lead to legal or financial consequences.
