Digital Forensics is a field of computer security specialized in examining IT systems for suspicious activity. In addition to data recovery, this field focuses on data tracing and cross-drive analysis. This field often combines with incident response efforts to form a solution called digital forensics and incident response.
Cross-Drive Analysis
Cross-drive
analysis is an investigation process that involves correlating information from
various data sources. This process helps investigators identify patterns or
anomalies that can be used as baselines to detect suspicious events. It is a
commonly used technique in data breach investigations. This is particularly
useful when attackers are thought to be insiders, so they are unlikely to leave
any digital artifacts behind.
Depending on
the type of digital evidence needed, digital forensics experts perform various
kinds of analysis. These include image, video, and file system analysis.
The SWGDE's Best Practices for Forensic Image Analysis recommend using tools to
acquire data from digital video recorders and cloud storage.
The typical
digital forensics procedure includes four stages: acquisition, examination,
analysis, and reporting. Each stage involves different techniques, such as cross-drive
analysis. Cross-drive analysis allows investigators to quickly correlate
information from several different hard drives. This process will also enable
investigators to examine a computer's operating system. A third common
technique is data recovery.
Data Recovery
The need for data recovery is growing as the use of technology continues to increase. Nowadays, almost every desktop computer or laptop is equipped with a hard disk drive. Although these disks are the most common digital storage devices, they are not the only ones that can store data.
External media are also standard and
are used for secondary storage. These media can store large volumes of personal
and business-critical data. To recover data from external media, you should
contact a data recovery service with a proven track record.
Data recovery
services are helpful in many cases, from investigations to criminal cases. They
can help law enforcement agencies recover information from all digital devices,
including computers and mobile phones. By analyzing browser history, phone
records, and file transfers, digital forensics experts can provide valuable
evidence to prosecute a suspect.
Evidence Protection
Evidence
protection is becoming increasingly important in the digital world. Cybersecurity
incidents cost businesses $4 billion annually, and forensics tools are
essential for recovering after a breach. Digital forensics is a forensic
science branch examining and analyzing digital evidence to help solve crimes.
It is also a vital part of the incident response process, allowing law
enforcement agencies to identify the source of a breach, identify threat
actors, and eradicate the problem.
Digital
forensic services provide evidence that can be used in legal proceedings or an
audit. They can also provide expert witness testimony for an investigation.
These services include malware analysis, reverse engineering, and sandbox
testing. They can also help identify threat actors and identify malware
samples. They can also help prevent the spread of malware, the primary source
of most cybercrimes.
Another branch of digital forensics is forensic data analysis. This field examines information in the form of emails, documents, and other data on a computer. The data in these documents are divided into two types: structured and unstructured. Structured data comes from computer application systems.
Unstructured data, on
the other hand, comes from communication, office applications, and mobile
devices. The data in these types of files are not stored in a structured manner
and require computer forensics experts to extract their forensic value.
Data Tracing
Digital
forensics services can
significantly benefit the investigation of computer-related crimes. Such
services can aid in the recovery of data lost or stolen and help prevent crimes
such as online fraud or harassment. All law enforcement agencies have cyber
cells to handle such investigations.
Aside from helping companies recover their stolen data, digital forensics also helps build evidence for legal cases. It can also be used to detect the leakage of private information and trade secrets. Such information can be precious to a company, and the services of a digital forensics expert can help the company preserve its reputation.
Unfortunately, the business world is full of fraud and data
theft. However, digital forensics experts can uncover those behind these acts
by tracking down their digital fingerprints and monitoring their online
activity.
Digital forensic services use new software and techniques to retrieve and analyze the data on a computer. Before the advent of digital forensic tools, digital investigations were conducted through live analysis, which became increasingly difficult and inefficient as devices grew more complex and packed with information. Today, these tools are used to analyze various data types, including email, video, files, and more.
