Cognosec can assist you with your digital forensics investigations. This is the application of science to the identification, collection, examination, and analysis of data while preserving the integrity of the information and maintaining a strict chain of custody for the data.
The process for performing digital forensics comprises the following basic phases: Collection: identifying, labeling, recording, and acquiring data from the possible sources of relevant data, while following procedures that preserve the integrity of the data. Examination: forensically processing collected data using a combination of automated and manual methods, and assessing and extracting data of particular interest, while preserving the integrity of the data. Analysis: analyzing the results of the examination, using legally justifiable methods and techniques, to derive useful information that addresses the questions that were the impetus for performing the collection and examination. Reporting: reporting the results of the analysis, which may include describing the actions used, explaining how tools and procedures were selected, determining what other actions need to be performed (e.g., forensic examination of additional data sources, securing identified vulnerabilities, improving existing security controls), and providing recommendations for improvement to policies, procedures, tools, and other aspects of the forensic process.
Over the last decade, the number of crimes that involve computers has grown, spurring an increase in companies and products that aim to assist law enforcement in using computer-based evidence to determine the who, what, where, when, and how for crimes. As a result, computer and network forensics has evolved to assure proper presentation of computer crime evidentiary data into court. Forensic tools and techniques are most often thought of in the context of criminal investigations and computer security incident handlingóused to respond to an event by investigating suspect systems, gathering and preserving evidence, reconstructing events, and assessing the current state of an event. Cognosec can assist you with your digital forensics investigations. This is the application of science to the identification, collection, examination, and analysis of data while preserving the integrity of the information and maintaining a strict chain of custody for the data.
During a forensic investigation Cognosec will identifyi potential data source and acquire the data from the sources. Data acquisition will be performed using a three-step process:
- developing a plan to acquire the data
- acquiring the data
- verifying the integrity of the acquired data
After data has been collected, the next phase is to examine the data, which involves assessing and extracting the relevant pieces of information from the collected data. This phase may also involve bypassing or mitigating OS or application features that obscure data and code, such as data compression, encryption, and access control mechanisms. Once the relevant information has been extracted, Cognosec will study and analyze the data to draw conclusions from it and then prepare and present the information resulting from the analysis phase.
