Which of the following is a common challenge in digital forensics?

The rapid advancement of technology is indeed a common challenge in digital forensics. As technology evolves, new devices and systems are developed, which can introduce complexities into the forensic process. Forensic investigators must continually update their skills and adapt their methodologies to stay current with the latest technologies, software, and encryption techniques used by individuals and organizations. This rapid change can make it difficult to effectively gather, analyze, and present digital evidence, as tools and techniques that were effective yesterday may not be sufficient today.

In contrast, while insufficient data backup can certainly pose challenges in specific cases, it is not an overarching issue affecting the field of digital forensics as a whole. Similarly, the overabundance of physical evidence is less relevant in a field that primarily deals with digital sources of evidence. Lastly, low rates of cybercrime do not reflect a challenge within the discipline, as digital forensics often gains significance in response to the growing prevalence of cyber incidents. The continuous technological evolution remains a dominant theme and challenge in the digital forensics landscape.
