A variety of analytical tools and techniques are used for the discovery of evidence or the examination of documents relevant to a criminal investigation or other legal proceeding. This medico-legal evidence may take the form of biological samples, traces of trace materials and residues, contaminants, counterfeit products or hoaxes.
RAM Lab is a specialized center within our cybersecurity operations center dedicated to the search and analysis of internal threats. By conducting regular threat investigations, such as in-depth malware scans, our experts deepen their understanding of the latest malicious actors and use them to improve our range of security services, including proactive monitoring of networks and devices. We often hear about security incidents in the world around us. Recently, a PCIDSS claim organization in the United States has been hacked. Forensic analysis is the analysis of such an incident. In short, Forensics involves discovering how, who, when, and where of an incident.
In the forensic analysis, a set of considerations should be kept in mind. For example, systems subject to external influences must be isolated in order to avoid further damage or preserve evidence. This is not a forensic analyst task, but rather a step that must be taken by the incident response team shortly after the incident is detected. In these cases, the forensic analyst must always work with the incident response team to make decisions about containment, such as disconnecting network cables, feeding devices themselves, increasing physical security measures, or even turning off the device. These decisions must be made on the basis of existing policies; these teams know the real impact of the problem and are aware of the risk of duplicating certain actions on the system.

Forensic Analysis Process Includes
It is a structured process to identify what happened, how and why, what can be done to reduce the risk of recurrence and make care safer, and what has been learned .
It is an integral activity of the Incident Management Continuum, which represents the activities and processes surrounding a patient safety incident. …………………………………………
They are considered important for rigorous analysis because they can reflect aesthetic taste, values, motivations, and rhetorical decisions within a given culture.
RAM Forensic Analysis describes some common issues for artifact analysis as well as commonly used frameworks, including cultural studies, semiotics, material rhetoric, and design.
Security Profile Assessment
It is available as a one-time or periodic service. In addition to the benefits of a one-time evaluation, the periodic service allows you to track your exposure to risk over time and measure changes and trends in your security risk levels.
New risks are constantly being created by configuration changes, new services or software, and vendor security announcements, making it difficult to manage your security exposure.
It is a systematic assessment of the defenses of your enterprise IT infrastructure. Our security professionals measure the compliance of your security protocols with a list of established criteria to validate their security posture.
These audits must be deepened and carried out regularly to secure your data and your digital assets. ………………………………………………………………………………………………………………………………….
In this scenario, a security expert will try to replicate the same methods used by bad actors to determine if your IT infrastructure could withstand a similar attack.
It goes beyond security audits and vulnerability assessments by attempting to violate your system like a hacker.
It refers to examining the risks associated with a particular action or event. Risk analysis is practiced regularly and updated to identify new potential threats.
Strategic risk analysis minimizes the probability of risk and future damage. ……………………………………………………………………………..
It is also known as Vulnerability Testing, is a type of software test performed to assess security risks in the software system to reduce the likelihood of a threat.
Our Methodology of Forensic Analysis
The analysis of large volumes of data is usually done in a separate database system managed by our analysis team. Live systems are typically not dimensional to perform deep individual analysis without affecting the usual users. On the other hand, it is methodically preferable to analyze the copies of data on separate systems and to protect the analysis teams against the charge of modifying the original data. Due to the nature of the data, the analysis focuses more often on the content of the data than on the database in which it is contained. If the database itself is of interest, the database scans are applied. To analyze large sets of structured data with the intention of detecting financial offenses, at least three types of expertise are required in the team: a data analyst to perform the technical steps and write the queries, a member of the team team with extensive experience in internal processes and controls in the relevant sector of the company being investigated and forensic expertise who is familiar with patterns of fraudulent behavior.
After an initial analysis phase using exploratory data analysis methods, the next phase is usually very iterative. Starting from an assumption about how the author might have created a personal benefit, the data are analyzed to provide supporting evidence. Following this, the hypothesis is refined or rejected. The combination of different databases, especially data from different systems or sources, is very effective. These data sources are unknown to the author or are such that they can no longer be manipulated by the author later.
Forensics is done for various purposes with different goals:
Establishing proof of a crime / hack; Data recovery in case of unforeseen event; Find the vulnerability that allowed a hack; Follow an employee’s activities.
Log Analysis is an important part of forensic science. When analyzing an incident, it is very important to be clear in your objective. Collect the collect according to your needs. There may be different types of logs, which may not be useful for the analyzed incident. It is therefore very important to understand the purpose and collect the appropriate logs.
Some logs which we have collected are listed below:
For Windows Operating System
- Application logs from the event viewer.
- Security logs from the event viewer.
- System logs from the event viewer.
After log collection, what next?
Now the collected logs are analyzed. Log analysis is either done manually or using log analysis tools. Several free and paid tools are available for log analysis. These tools are very useful. They take raw data as input and present it in a human-readable format. Today, log analysis tools support all types of log formats. A single tool can take RAM antivirus logs, router logs, Windows event / security logs, and more. for analytical purposes.
Then, we apply various filters to the data presented by the tool, according to the needs and the objective. These filters remove unwanted data and allow you to focus your analysis on the remaining data. Advance in this way until the desired goal is reached. Thus, by combining the manual analysis approach with the help of tools, a Forensic analysis is performed effectively.
We can help you create a robust security environment with services including threat assessment, strategy review and development, and master planning. The security decisions you make today can determine the security and resilience of your organization for years to come. Our comprehensive security consulting services allow you to be more confident about the steps you take to protect your family office, employees, operations, facilities and assets.
What Are Standard Operating Procedures?
The document Standard Operating Procedures for Computer Forensics defines review requirements, process structures, and documentation. According to this document, there are four stages of examination:
- Visual Inspection: The purpose of this inspection is simply to determine the type of evidence, its condition and relevant information to conduct the examination. This is often done during the initial capture of evidence. For example, if a computer is being entered, you may want to indicate if the computer is running, what state it is in, and what the general environment looks like.
- Forensic Duplication: This is the process of duplicating media before the exam. It is always recommended to work on a forensic copy and not on the original.
- Media Examination: This is the real medico-legal test of the application. By media, we mean hard disk, RAM, SIM card or any other element that may contain digital data
- Evidence Return: Exhibits are returned to the appropriate location, usually locked or secure facilities.
What RAM products offer ?
Antivirus is one of the most widely used tools for detecting and stopping malicious and unwanted files. However, the long-term effectiveness of traditional host-based antivirus is debatable. Antivirus software fails to detect many modern threats and its increasing complexity has resulted in vulnerabilities exploited by malware. Our Antivirus RAM advocates a new end-user malware detection model, based on the provision of antivirus as a network service in the cloud. This model allows the identification of malware and unwanted by multiple parallel heterogeneous detection engines, a tool we call “RAM Malware Removal”. This approach offers several important benefits, including improved malware detection, enhanced forensics, retrospective detection, and enhanced deployability and management. We evaluate the performance, scalability, and efficiency of the system using data from an actual deployment of more than six months and a database of approximately 1 TB of malware samples covering a period of one year.
