Reverse Presentation

The document discusses reverse engineering and its uses. It notes that reverse engineering can be used to recover lost information, such as recreating a Java file that was accidentally deleted. Reverse engineering also helps with software maintenance and migration. It aims to determine how a product works by analyzing its components and technology. Approaches to reverse engineering include abstraction, system analysis, and re-implementation of the system. Common tools for reverse engineering include Java decompilers, UML modeling tools, and architecture design software.

RE encompasses any activity that is done to determine how a product works, to learn the ideas and technology that were used in developing that product. RE can be done at many levels RE generally belongs to Software Maintenance .

Recovery of lost information


providing proper system documentation

Assisting with maintenance


identification of side effects and anomalies

Migration to another hw/sw platform Facilitating software reuse Malware research & defence Review and audit of software/security system

Benefits
maintenance cost savings quality improvements

competitive advantages
software reuse facilitation
