Digital Forensics & Incident Response : Digital Forensics Tools 2020

Digital Forensics & Incident Response : Digital Forensics Tools 2020

Cybercrime is the most chanting word that appears in the daily headlines. Many of the businesses and private industries stuck in the spider web of cybercrime. The need for Digital Forensics is mandatory for companies to get out of the loophole of cybercrime.

Digital Forensics

It is the process of interpreting and uncovering electronic data. Only the science that is exactly dealing the electronic crimes. It is used to get the evidence of any from its original form by making an investigation on collecting, validating, and identifying the digital information. It helps to reconstruct past events.

The incident response aims to examine the vulnerabilities exploited by the advisory. That helps in understanding the way adversary attacks the systems and finding the compromised credentials and systems also the exposed information.

Furthermore, digital forensics can be used in performing systematic investigation when the documentation of the chain of evidence did. It is significant in identifying the factors that emerged in the digital system and who is most responsible for that.

At the endpoint, digital forensics is challenging to tackle as we need to face the challenges that contain data and systems, the potentiality of pulling the data, languages, synthesizing multiple sources data, etc.

If you are intended to an investigation cybersecurity incident, then it is necessary to launch the examination of data on multiple digital devices such as mobiles, computers and memory sticks, etc.

Uses of Digital Forensics

The scene of a crime can be digital. That means hacking, holding the evidence in the form of emails, documents, other files, or internet history through which it can be misused.

The examination digital forensic report helps to reveal that when the document was edited at last, when it appeared initially when it printed or saved and who is responsible for carrying out those actions.

Most of the organizations are in the use of digital forensics in many cases like

  • Industrial spying
  • Intellectual property theft
  • Scam investigations
  • Forgeries
  • Inappropriate use of internet and email especially in the workplace
  • Employment clashes
  • Supervisory compliance

Digital Forensics Glossary

Metadata:

Metadata can be defined as information about other data. Here the data is stored in separate files on somewhere else, or the files contain the metadata. The data format, it’s an author, and the data creation date will be included in the metadata.

Hacking:

Hacking is the process where it involves to change the mobile or computer device from its original purpose. The system hacker always keeps hands to hack the system spitefully. Some people are in the intention of hacking their system to hide their first activity on the network.

Bit Copy:

It can be defined as the successive copy of the individual binary digit, which specially located in the storage medium. Even the standard user can not see the bit copy.

Keylogging:

The working of keylogging is that it captures the information of the user typed on a device or computer. A remote user can have the accessibility to obtain sensitive data and passwords by using keylogging.

Write-Blocker:

It is either the hardware device or software application. As the name itself defines its activity of protecting data and preventing theft or modifications.

RAM:

Everyone knows about it. It is the memory of the computer or device which works temporarily. Any information which is left in the RAM disappears when the user turns off the system.

Why is Digital Forensics on the rise?

The usual usage of digital devices the cybercrime is always on the upper hands to the hype on headlines.

  • The loss of $12.t million occurred due to cybercrime in the US in 2014, according to reports.
  • It is 9% up from 2013, where the figure of loss is $11.6 million.
  • The loss due to cybercrime is from $375 million to $525 million globally.

From the above statistics, it very clear that the rise of cybercrime day by day leads to involving digital forensics.

By 2021 the Digital Forensics predictable to be a Billion Dollar Industry

Digital forensics is composed of three parameters, such as mobiles, computers, and networks. All these areas need mastery of software-hardware tools.

Software:

Slueth Kit:

It is the open-source software that can be used to recover the last documents, analyzing registry changes, especially on Windows, Unix, Mac, Linux, DOS, etc.

Crowdstrike:

The contextual data like scheduled tasks, shim cache, and process lists can be gathered with the help of lightweight console Crowdstrike. The user can also scan the malware host by immersing the embedded YARA signatures.

Registry Recon:

It can make analyzation and rebuilding the windows registry.

Volatility:

This digital forensic tool helps to extract the data stored on the RAM.

Caine:

It provides an integrated set of mobile, network, and memory forensic tools.

Hardware:

Fred:

It is the evidence device of forensic recovery, and these analyze the data on high-speed networks by plugging directly.

Capture screens:

It is the hardware of evidence grade which can capture information from DVDs, CDs, mobile devices, and flashcards.

Forensic bridge:

The data from storage media can be safely extracted by connecting these devices.

Shadow:

At the scene of cybercrime, it helps to protect the suspect’s hard drive.

Ethics of digital forensics

  • The investigation should not compromise the information on storage media or devices being accessed.
  • The records of the fetched methods, process, and each tool should be maintained as the act of investigation.
  • They should explain the action they take by providing evidence of relevant information.
  • The supervisory of the investigation should exhibit the responsibility of following the guidelines mentioned above.

Stages of Digital Forensic Investigation

Analysis:

To review the fetched conclusions and raw data, the number of methodologies and tools is used.

Seizure:

It helps to obtain the physical device that can be used to store the information on the device.

Acquisition:

The integrity of the original data is stored to store the honesty of the investigation. Simply a copy of the information is stored on the device.

Reporting:

The sharing of investigation results can be done by including the specific activity of the arrival of those results.

Digital Forensics Statistics

  • The digital forensics market may reach $7 billion by the year 2024, Says Variant Market Research.
  • The digital forensic market over mobile devices reaches to rise at a CAGR of 16.4% by 2027.
  • The digital forensic marketer is going to rise at a CAGR of 12% by 2023.
  • In 2025 the global gesture recognition market size may reach CAGR of 22.2%.
  • The digital utility market size may reach at a CAGR of 11.6% during the period 2025.
  • Ericsson’s Mobility report says that the Internet of Things (IoT) devices may reach 18 billion by the year 2022.

Conclusion

The investigation involves in digital forensics will provide safety measures for the industries from the hackers who are playing a role in committing cybercrime. It also includes the advanced safety parameters before facing the cybercrime.
