Forensic sciences or criminalistics are referred to as the sciences that work towards revealing the material truth and solving crimes and legal disputes. Forensic sciences are not a standalone field of science; rather, they encompass a wide range of different disciplines serving forensic purposes.
It also serves to prevent wrongful accusations and punishments of innocent individuals until the perpetrator of the crime is identified. In the context of forensic sciences, crime and dispute matters are treated as an “event,” and only the truth is investigated.
Gmka Defense continues to carefully work on forensic sciences to focus on accurate correlations and to monitor events in real-time while identifying a crime.
Forensic analysis comes into play when data is accurately analyzed to obtain actionable intelligence for detecting forensic crimes that cover various fields. The purpose of forensic analysis systems for crime detection is to ensure that organizations and sectors stay up-to-date with the technologies of forensic sciences. One of the most significant concerns for society is the detection and prevention of forensic crimes. In this field, where detailed relationships and hidden connections are crucial, clues obtained through accurate analysis hold vital importance.
Secure data erasure is essential for both the private sector and public institutions, which contain sensitive information that needs to be kept confidential (personal data, sensitive private information, personnel records, institutional policies, R&D studies, credit card numbers, financial records, etc.). Nowadays, digital data is stored in computers, servers, and storage units.
The importance of protecting, storing, and backing up digital data against threats is often emphasized, but the secure and permanent destruction of data is frequently overlooked. It is known that simply using standard deletion commands for data no longer needed is not sufficient. Such data requires secure and permanent destruction.
Misuse investigation requires a comprehensive examination for detecting cases of misuse:
– Creation of misuse analysis reports,,
– Presentation of all suspicious transactions with relationship diagrams,
– Preparation of legal reports along with expert opinions for the use of evidence in legal processes.
As a result of our work, we also prepare sensitivity analysis reports and present a recommendation report for taking necessary precautions to prevent misuse from happening again.
Data recovery is a delicate process that requires in-depth examination to achieve the best results. These magnetic devices are manufactured with both mechanical and electronic components, and all memory devices are produced in a sterile manner. The most common types include SATA, IDE, SAS, SSCI, SSD and SSHD. Their widespread use, increasing capacities, and the intensity of evolving technology have led to a significant rise in their usage not only in commercial enterprises but also on an individual level, resulting in a substantial increase in data loss incidents due to the nature of technology. Hence, even a tiny speck of dust or an improper intervention on the magnetic platters can cause damage to the data.
Images obtained from various sources such as bank security cameras, traffic cameras, building security cameras, mobile phone cameras, professional or compact cameras are now encountered everywhere and accepted as evidence.
For examinations, various processes are carried out, including image enhancement or restoration, alterations on the original image (such as montage or manipulation), detection of specific traces, object and person comparison, and similar operations. In some cases, the integrated analysis and explanation of audio and visual data of a specific event may also be necessary.
Material analysis is an analytical technique used to identify organic, polymeric, and sometimes inorganic materials. Infrared spectroscopy analysis uses infrared light to scan test samples and determine their chemical properties. The infrared spectrometer device emits radiation, and the absorbed radiation is converted into vibrational energy by the sample molecules. Each molecule or chemical structure produces a unique spectral fingerprint. By performing material analysis in this way, chemical identification is achieved. It is used for identifying and characterizing unknown materials, identifying contamination in a material, identifying additives in a polymer matrix after extraction, and identifying oxidation, degradation, or uncured monomers in failure analysis investigations.
Sound is obtained from any recording device that may serve as evidence in any legal case and can help illuminate the events. These sounds are accepted as evidence and can be obtained from analog or digital recording devices, video cameras and cameras that record sound, certain security cameras (with built-in microphones), mobile phones, and any other recording devices. Sometimes, brief conversations or even a noise can hold clues to unresolved issues or help analyze all details clearly. Analyzing non-speech audio and texts, linking them together or associating them with a person, determining the authenticity of sounds within a recording, cleaning up noise, extracting the speaker’s profile, and identifying the signal source are fundamental areas of investigation.
Forensic computing, in today’s world, has rapidly developed and become a significant part of our lives due to the increasing use of technological devices. As it contains a vast amount of data in our lives, it has found its place in the field of forensic sciences for illuminating legal matters. It is a branch of combating cybercrimes and involves collecting and examining evidence related to committed crimes
It covers all kinds of data (sound, images, text, etc.) preserved or transmitted in electronic environments and encompasses the process of defining, obtaining, storing, examining, and presenting such data as digital evidence to legal authorities
Forensic computing examinations do not necessarily have to be related to a specific legal case. In some cases, it may be necessary to examine a computing device for reasons unrelated to a legal event, arising from everyday life needs.
