Overview
As technology advances at an unprecedented pace, it becomes increasingly important to safeguard a company’s digital assets—the point where Computer Audit and Forensics come in. With computer audits, auditors assess a company’s financial and operational IT systems, including hardware, software, and data.
On the other hand, computer forensics analyzes digital data to investigate cyber-attacks, prevent potential security breaches, and recover lost data.
Protecting a company’s digital assets is paramount as it contains valuable confidential information such as intellectual property, client records, vital financial documents, and critical business operations. If left vulnerable, these assets can result in significant losses.
Common cyber-attacks such as hacking and data breaches are on the rise, and companies must invest in adequate cybersecurity measures to avoid the negative consequences of compromised data.
An In-Depth Guide to Computer Audit and Forensics for Businesses of All Sizes
For a comprehensive approach to computer auditing and forensics, organizations should seek the expertise of professionals who understand the technical and business aspects of their operations.
Implementing robust security measures such as firewalls and intrusion detection systems is essential while establishing data protection and incident response policies. Additionally, companies must have a plan to gather, preserve, and analyze digital evidence in case of suspected wrongdoing or security breaches.

Geotech Techniques Used in Computer Audit & Forensic:
We engage in the following process: acquisition, examination, analysis, and reporting, typically followed by computer forensics investigations. Even though in the early days of computer forensics, the investigators had to work on live data due to a lack of tools, these investigations are now typically conducted on static data (disk snapshots) rather than live data or live systems.
The approach we use in computer Auditing and forensics:
Cross-drive analysis:
We swiftly locate and correlate data from several data sources or data spread across numerous drives using the cross-drive analysis (CDA) technique. Multi-drive correlation using text searches, such as email addresses, SSNs, message IDs, or credit card information, is one method already in use.
Live Analysis:
Used to inspect computers from within the operating system utilizing several forensics and system administration tools to obtain data from the device. Gathering volatile data for forensic investigation, such as installed software packages, hardware details, etc., is crucial.
When the investigator is working with encrypted files, this method is helpful. The investigator should get all the volatile information from the device, such as user login history, open TCP and UDP ports, services that are now in use and operating, etc., if the device is still alive and running when given to the investigator.
Deleted files Recovery:
It’s a method for getting back deleted files. The erased data can be retrieved or desired with the aid of forensic programs like CrashPlan, OnTrack Easy Recovery, Wise Data Recovery, etc.
Stochastic forensics:
It is a technique for forensically reconstructing digital actions with insufficient digital evidence, allowing for auditing a new pattern brought about by the stochastic nature of contemporary computers.
Steganography:
Steganography is a method for concealing hidden information on top of or inside anything, including anything from a file to an image. You can avoid this by computer forensics investigators by comparing the hash values of the original and altered files. Although they may appear identical upon visual inspection, the hash values of the two files will differ.
