The Crime Scene Investigation
You can get large evidence bags, tape, tags, labels, and other products from police supply vendors or office supply stores. The crime scene investigation is the beginning of the process of using physical evidence. The crime scene procedures include physical evidence recognition, documentation, proper collection, packaging, preser- vation, and, finally, scene reconstruction.
The charred debris must be sealed in an airtight container to prevent the release of volatile petroleum residues. Airtight containers can cause condensation of water within them, which can causebacteria that can destroy, alter or taint the blood. Paper bags, envelopes, boxes and similar materials are used for biological evidence.
Plastic packaging is not a good idea. The use of pill tins can cause rust. All evidence and samples should be dry.
Once in a secure location, wet evidence must be removed and allowed to dry out. The evidence can be put in a new container. The crime scenes are considered either primary or secondary.
The primary crime scene is where the crime happened. A secondary crime scene is related to the crime but not the actual crime. The first officer to arrive is responsible for securing the scene.

Forensic Software for ESI
The selection of software applications specific to a certain need has given forensic examiners the ability to provide more depth to an aspect. Current forensic software is almost described as point and click applications, compared to early forensic software which was not easy to use. The speed of electronic evidence collection is simply incredible, as compared to any previous year.
The collection of specific information from a computer system is an example of a collection. Smaller and more focused applications may be more efficient than a fully featured forensic suite. Even though there have been improvements in how digital forensic tools and techniques can be used to reduce the time required to work with evidence, there is still an underlying issue of how organization can efficiently manage the data volumes that need to be gathered and processed during a forensic investigation.
There is a need to design a storage solution that can easily adapt to the constantly growing volumes of data that need to be accessed in both real time and near real time. Storage solutions such as an EDW allow organizations to store both structured7 and unstructured8 data in a way that can be easily and dynamically adjusted to changing storage capacity requirements. It is important to remember that there is always the chance of accidentally changing the original data source when working with ESI.
Digital Forensic Tools
Thousands of digital devices that have been seized by police as evidence for alleged crimes, including terrorism and sexual offenses, are sitting in storage in a growing back-up that investigators are struggling to tackle. Digital investigations were done via live analysis and using the device in question to examine digital media was commonplace in the 1990s. The use of devices with huge amounts of information has increased.
A GUI-based tool suite for private sector digital forensics
Digital forensics is a widely used craft by investigators in all sectors, whether it is providing valuable evidence that assists in the investigation and prosecutions of crime perpetrators or proving their innocence. Digital forensics is currently being challenged by the ever-growing advancement of information technology, but its tools and techniques are continuously used to collect, process, preserve and analyze evidence from a range of digital devices, help uncover vulnerabilities and threats and ultimately help inform ways to mitigate them. Digital forensics is used in businesses of all sizes in the private sector.
It can be used in large organizations and corporations to deal with security incidents. Digital forensics professionals can be hired by organizations to investigate after a data breach, cyber attack, network compromise, intellectual property theft, cyber espionage, issues with regulatory compliance, and more. There are incidents that can be referred to digital forensics examiners that are not malicious in nature.
The private sector uses a more automated approach to digital forensics investigations than the strictly scientific approach used for cases within the legal frame. The first step in any investigation is to identify the objective, sources of evidence, what type of devices are involved, what type of data is needed, and what format. Digital forensics analysts will collect data using methods that are authentic when the digital devices that will be used in the investigation are identified and taken.
The Sleuth Kit and Autopsy are the most popular open source digital forensics tools for recovering data from file systems and raw-based disk images. The Sleuth Kit is a command-line tool that performs disk image and data recovery and Autopsy is its GUI as well as a digital forensics system used in private and public investigations. CAINE is a complete Linux distribution for security research and digital forensics analysis.
CAINE includes the best forensics software available, both command-line and GUI-based, and it allows analysts to extract data from multiple sources. The Sleuth Kit, Autopsy, Wireshark, and PhotoRec are some of the popular tools that CAINE has. ProDiscover offers a product suite that includes solutions for incident response and electronic discovery as well as a wide array of diagnostic tools.
Forensic Investigation and Analysis
In forensic, investigation and analysis techniques are used to assemble and preserve evidence from a specific computing electronic equipment in a way that they are suitable for presenting in a court of law. The main goal of computer forensics is to study a well- structured subject of the investigation while detailing a documented analysis sequence of evidence or proof to figure out what has occurred on an electronic device and the people who are responsible for it. The forensics is used to point out the hidden private details that the area unit has left.
The goal of forensics is to look, preserve, and analyze the data in a very detailed form on a computer system to find out a potential proof for an attempt. The Computer-Aided Investigative Environment is a Linux Live CD that is used forensic investigations. It is a report generator that can be used to get the results in a short time.
CAINE is based on Linux and LightDM. It has a user-friendly interface. registry recon is a very advanced tool
It looks at the data stored in the evidence and rebuilds its representation. It is not free, but it is a cost to use. It is a tool that can be used to find files, images, or directories on a disk.
Digital Forensic Analysis
Digital forensics is an application that can be used to determine a scientific examiner method to digital attacks and crimes. It is an essential condition of both laws and business in the modern era of technology and could be an advantage in its career. Digital forensic is the process of analyzing and preserving digital evidence and showing it to the court in a court of law.
It is a method of discovering proof from digital media like a PC, mobile or cellular device. It gives the forensic department group the equipment and procedures to solve difficult digital cases. It is the first step in the process that will include the forensic process, where the evidence is found, and the way it is stored.
Digital Forensic Investigation
Digital forensic is the process of preservation, identification, extraction, and documentation of computer evidence which can be used by the court of law. It is a science of finding evidence from digital media. It gives the forensic team the best techniques and tools to solve complicated digital-related cases.
Digital Forensic Science
Digital forensics is a branch of forensic science that deals with the recovery and investigation of material found in digital devices and cybercrimes. Digital forensics is a synonym for computer forensics and covers the investigation of all devices that store digital data. Digital forensics is concerned with the preservation, examination and analysis of digital evidence, using scientifically accepted and validated processes, to be used outside of a court of law.
It is associated with criminal law where evidence is collected to support or refute a hypothesis. Intelligence gathering may include the collection of evidence to locate, identify or halt other crimes. Data gathered may be held to a less strict standard than traditional forensics.
There are a number of open-sourced tools that are used to speed up the examination of database files. There are also commercial platforms with multiple functions and reporting capabilities like Encase or CAINE. Digital media is examined by national and international legislation.
Laws may limit what can be examined. Network monitoring and personal communications are not allowed. Criminal investigations may be restricted by national laws that dictate how much information can be seized.
The United Kingdom has a law that governs the seizure of evidence by law enforcement. Civil investigators in the UK are hard-hit by the 1990 computer misuse act. One of the most undecided considerations is an individual's right to privacy.
Redline: A tool for digital forensics
Digital forensics tools are new. Digital investigations used to be conducted through live analysis, which meant examining digital media by using the device in question as everyone else would. Live analysis became more cumbersome as devices became more complex.
freeware and proprietary specialist technologies began to crop up as both hardware and software to carefully sift, extract, or observe data on a device without damaging or modifying it If a full search takes hours, a user will know within minutes if a targeted search has been found. A central repository can be created through Autopsy that will flag phone numbers, email addresses, or other relevant data points.
The Bulk Extractor can access different parts of the disk in parallel, making it faster than the average tool. The second advantage of Bulk Extractor is that it can be used to process almost any type of digital media. The most recent versions of Bulk Extractor can perform social network forensics as well as extract addresses, credit card numbers, URLs, and other types of information from digital evidence.
The ability to create histograms based on frequently used email addresses is one of the capabilities. Digital copies of hard drives are needed to work properly, and evidence can be obtained from them. The original integrity of the evidence is not affected by the analysis of the images of the drive.
Redline is a tool that provides free security and investigative capabilities for users, but was later taken over by FireEye. It can be used to collect and correlate data around event logs, running processes, file system, web history, and network activity, but it is mainly used to perform memory analysis and look for signs of infections. It can sift through a lot of files on almost all 32-bit and 64-bit machines.
