Digital forensics is a crucial domain in cybersecurity. It reveals vital evidence related to digital information assets and internet-related crimes. In order to carry out these investigations, developers have created many digital forensics tools. While forensic investigators choose these tools because of various factors including budget, availability, and others, one of the best digital forensic tools that almost every investigator turns to is CAINE (Computer Aided Investigative Environment).
What is Digital Forensics?
Earlier, the branch was popularly known as computer forensics, as computers were the only devices producing digital data. But through the years, this domain has expanded to all devices generating and storing digital data. The primary goal of digital forensics is to conduct an organized investigation on digital devices involved in a cybercrime with the goal of preserving the evidence in its original form. Digital forensic experts collect, identify, and validate the digital information to reconstruct past events. If done correctly, the gathered data can help track down perpetrators. Forensic security also helps organizations learn from security breaches and defend against future attacks by elucidating exactly how an attack was carried out and how the attackers gained access to a network.
All About CAINE
CAINE is a professional open-source forensic platform that integrates powerful scripts into its GUI. The tool is an Italian GNU/Linux live distribution, which offers an operational environment for forensic investigative processes, including preservation, collection, examination, and analysis.
The platform is a live Linux distribution, and users can boot it using a flash drive or an optical disk. It can also be run on memory. There are a few other installation options that involve physical as well as virtual systems.
To download CAINE, visit the CAINE Live download page. It is now in its 11th version, which can be booted on UEFI/UEFI+Secure and Legacy BIOS. Also, it allows the platform to be installed on older as well as new operating systems, including Windows NT, Linux, and even Windows 10.
5 Key Features of CAINE Suite
1. Offers a complete forensic environment
CAINE presents an interoperable environment that integrates existing software modules and a user-friendly graphical interface.
2. Report compilation
In the final analysis of the digital forensic process, CAINE compiles complete documentation of case management. With the help of this feature, investigators do not need to compile a report manually.
3. Reliable data
Since CAINE claims to be forensically sound, it helps the investigator to obtain reliable data and digital evidence.
4. Allows cloning
It is possible to clone CAINE using Clonezilla, a computer program. With the help of this feature, the platform creates backup and allows computer imaging. However, the only catch is you need to have a destination drive of equal or larger size than the source drive.
5. Centralization for important software tools
CAINE provides several software tools that are helpful in memory, database, forensic, and network analysis. A few of these tools include –
|The Sleuth Kit||The Sleuth Kit is a free, open-source suite that offers command-line tools. It is a combination of Unix- and Windows-based utilities that help forensic experts in digital forensic investigations. Additionally, the library can analyze different file systems – NTFS, FAT/ExFAT, UFS 1/2, Ext2, Ext3, Ext4, HFS, ISO 9660, and YAFFS2.
This suite includes a range of tools, including –
and many others.
|Autopsy||It is a software program that easily deploys the tools and plug-ins included in The Sleuth Kit. Basis Technology Corp maintains the tool.
Autopsy serves four purposes – extensibility, centralization, ease of use, and allowance to multiple users. Its open-source modules allow customization by allowing users to add modules. For instance, the “ingesting” module can help in scanning the files while the “reporting” module summarizes the report.
The earlier version of the tool (Version 2 of Autopsy) was written in Perl while Autopsy 3.0 was developed in Java using the NetBeans platform.
|Wireshark||Wireshark is a free, open-source network protocol analyzer. It was formerly known as Ethereal.
The primary objective of Wireshark is to capture network packets in a real-time environment and display its content in a readable format.
The tool supports all major operating systems including Linux, macOS, Microsoft Windows, BSD, Solaris, and a few other Unix-based operating systems.
Some of the outstanding features of Wireshark are –
