Digital evidence is indeed considered to be fragile in nature due to its susceptibility to alteration, deletion, or corruption. Unlike physical evidence, which can often remain unchanged over time if stored properly, digital evidence can be easily modified through user actions or system processes. For example, when data is accessed or opened, it may change or can leave residual data that affects the integrity of the original evidence.

Additionally, digital evidence requires careful handling to preserve its authenticity and integrity. This includes following specific protocols during data acquisition and analysis to prevent accidental contamination or modification. Factors such as hardware failures, data corruption, and even malware can pose threats to the preservation of digital evidence. Consequently, the fragile nature of digital information calls for stringent practices in forensic investigations, emphasizing the necessity of maintaining a clear chain of custody and utilizing write-blockers to avoid writing data to original media.

Taking these factors into account solidifies the understanding that digital evidence is indeed fragile, warranting careful and methodical handling to maintain its integrity throughout the investigative process.
