What is the focus of digital forensics?

Digital forensics is primarily concerned with the discovery, recovery, and analysis of evidence found in digital formats. This discipline plays a crucial role in investigations related to crimes involving computers and networks, as well as in the context of corporate security incidents. The focus is specifically on identifying, preserving, and presenting data that serves as evidence, ensuring that the integrity of the information is maintained throughout the process.

The other options relate to aspects of digital information but do not reflect the core of digital forensics. For instance, aesthetic design deals with the usability and visual appeal of digital archives, which is separate from forensic analysis. Enhancing database performance pertains to optimizing how data systems operate rather than discovering evidence. Securely deleting digital data is about removing information in a way that prevents recovery, which is the opposite of the forensic focus on preserving data. Thus, option B accurately captures the essence of digital forensics, emphasizing the analytic and investigative aspects of handling digital evidence.
