digital forensics has come a long way in the past thirty years, new technology has come out and its more effecient. digital forensics is extremely invaluable because without it we would not be able to solve a lot of the cases that have been solved. its value is that we can charge a lot of people for crimes that no one saw directly but did happen.

What is encryption and how does it work?

What is the purpose of encryption?

In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can... Wikipedia

Once data is acquired, the data and device need to be securely stored until they're needed for further investigation. Preservation is usually done in either physical or digital storage systems-or preferably in a smart management system that can integrate with evidence management systems.

The two challenges faced in a digital forensic investigation are complexity and quantity. https://www.startertutorials.com/blog/challenges-in-computer-forensics.html#:~:text=The%20two%20challenges%20faced%20in,difficult%20to%20understand%20such%20data.

# data[].attributes.attachment_link.readable_text
In this article we will look at challenges in computer forensics. We will look at various challenges in network forensics, technical forensics and legal forensics.

Although there are well-developed forensic techniques, cybercrime investigation is not easy. Huge amount of data is available and searching for evidence in that enormous data is not easy. Most of the existing tools allow anyone to change the attribute associated with digital data.

Encryption is a commonly used antiforensics technique and keyword search can be defeated by renaming file names. Cybercrime investigators often face a problem of collecting evidence from very large groups of files. They need to use techniques like link analysis and visualization. To find leads they need to use machine learning techniques (patterns).

Challenges in network forensics

Networks span multiple time zones and multiple jurisdictions

Network data will be available offline and online (real-time)

Real-time data requires ability to capture and analyze data on the fly

The data may involve different protocols

The data may be huge due to increasing bandwidth

A protocol might also involve multiple layers of signal (VoIP, HTTP tunneling)

Current forensic tools will not be able to handle real-time data and huge amount of data

There need to be a paradigm shift for network forensics techniques to analyze the real-time data and huge amounts of data. Duration of forensics investigation may vary, some simple cases might take a few hours and complex cases may take some years to solve.

Certain digital information other than the data itself may help in solving the case. Such information might include, data and timestamps of files, folder structure and message transmission tags. Real-time data collection is more complex as it needs to address legalities and privileges involved in surveillance.

Technical Challenges

The two challenges faced in a digital forensic investigation are complexity and quantity. The complexity problem refers to the data collected being at the lowest level or in raw format. Non-technical people will find it difficult to understand such data.

Tools can be used to transform the data from low level format to readable format. The quantity problem refers to the amount of data that needs to be analyzed. Data reduction techniques can be used to group data or remove known data. Data reduction techniques include:

Identifying known network packets using IDS signatures

Identifying unknown entries during log processing

Identifying known files using hash databases

Sorting files by their types

Legal challenges

Digital evidence can be tampered easily, sometimes, even without any traces. It is common for modern computers to have multiple gigabyte sized disks. Seizing and freezing of digital evidence can no longer be accomplished just by burning a CD-ROM. Failure to freeze the evidence prior to opening files has invalidated critical evidence.

There is also the problem of finding relevant evidence within massive amounts of data which is a daunting task. The real legal challenges involve the artificial limitations imposed by constitutional, statutory and procedural issues. There are many types of personnel involved in digital/computer forensics like technicians, policy makers, and professionals.

Technicians have sound knowledge and skills to gather information from digital devices, understand software and hardware as well as networks. Policy makes establish forensics policies that reflect broad considerations. Professionals are the link between policy and execution who have extensive technical skills as well as good understanding of the legal procedures.

Digital evidence is information stored or transmitted in binary form that may be relied on in court. https://nij.ojp.gov/digital-evidence-and-forensics

Computers are used for committing crime, and, thanks to the burgeoning science of digital evidence forensics, law enforcement now uses computers to fight crime.

Digital evidence is information stored or transmitted in binary form that may be relied on in court. It can be found on a computer hard drive, a mobile phone, among other place s. Digital evidence is commonly associated with electronic crime, or e-crime, such as child pornography or credit card fraud. However, digital evidence is now used to prosecute all types of crimes, not just e-crime. For example, suspects' e-mail or mobile phone files might contain critical evidence regarding their intent, their whereabouts at the time of a crime and their relationship with other suspects. In 2005, for example, a floppy disk led investigators to the BTK serial killer who had eluded police capture since 1974 and claimed the lives of at least 10 victims.

In an effort to fight e-crime and to collect relevant digital evidence for all crimes, law enforcement agencies are incorporating the collection and analysis of digital evidence, also known as computer forensics, into their infrastructure. Law enforcement agencies are challenged by the need to train officers to collect digital evidence and keep up with rapidly evolving technologies such as computer operating systems.
