Code Output:

Code Explanation:

The given program is a Python script intended for use in cyber forensic analysis, particularly for scanning files within a directory, calculating their secure hash algorithm (SHA-256) hash values to detect any potential changes or tampering, and logging this information for review.

Firstly, we import the necessary modules: ‘os’ for interacting with the operating system, ‘hashlib’ for cryptographic hashing, and ‘datetime’ for timestamping log entries.

The calculate_hash function calculates the hash of a given file using the specified hash type (SHA-256 in our default setting). It reads the file in blocks to handle large files efficiently, updating the hash object with each chunk.

Next, scan_files is a recursive function that walks through a directory and its subdirectories to locate files. It uses the calculate_hash function to compute the hash of each file and collects the pairs of file paths and their corresponding hash values in a list.

The log_incident function is responsible for recording the hash values with timestamps. This allows an investigator to maintain a record of hash values at different points in time, which is crucial for detecting unauthorized changes to file contents.

In the example usage under the if __name__ == '__main__': block, the script is set to scan a hypothetical ‘target_directory’. The file paths and their hashes are logged with detailed incident descriptions using log_incident.

In case of an error, such as if the directory does not exist or there are insufficient permissions to read a file, the script will print an error message to the console.

The expected output indicates that a forensic scan was initiated and completed, with results logged to ‘forensic_log.txt’.

As a result, the script fulfills its objectives by providing a tool for scanning files in a target directory, digesting them for verification purposes, and logging the outcomes to assist in a forensic analysis scenario. The architecture of the code facilitates scalability to include more complex features, such as comparing the current state of files against a known good state, integrating network capabilities to send logs to a remote server, or even implementing machine learning for anomaly detection based on file changes.
