What is Digital Forensics & Types of Digital Forensics

What is Digital Forensics?

Digital Forensics is defined as 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 like a computer, mobile phone, server, or network. It provides the forensic team with the best techniques and tools to solve complicated digital-related cases.Digital Forensics helps the forensic team to analyzes, inspect, identifies, and preserve the digital evidence residing on various types of electronic devices.

Objectives of Computer Forensics.

It helps to recover, analyze, and preserve computer and related materials in such a manner that it helps the investigation agency to present them as evidence in a court of law.
It helps to postulate the motive behind the crime and identity of the main culprit.
Designing procedures at a suspected crime scene which helps you to ensure that the digital evidence obtained is not corrupted.
Data acquisition and duplication: Recovering deleted files and deleted partitions from digital media to extract the evidence and validate them.
Helps you to identify the evidence quickly, and also allows you to estimate the potential impact of the malicious activity on the victim
Producing a computer forensic report which offers a complete report on the investigation process.
Preserving the evidence by following the chain of custody.

Challenges faced in Digital Forensics.

The increase of PC's and extensive use of internet access
Easy availability of hacking tools
Lack of physical evidence makes prosecution difficult.
The large amount of storage space into Terabytes that makes this investigation job difficult.
Any technological changes require an upgrade or changes to solutions.

Advantages of Digital forensics.

To ensure the integrity of the computer system.
To produce evidence in the court, which can lead to the punishment of the culprit.
Efficiently tracks down cyber criminals from anywhere in the world.
Helps to protect the organization's money and valuable time.

Disadvantages of Digital Forensics.

Digital evidence accepted into court. However, it is must be proved that there is no tampering
Producing electronic records and storing them is an extremely costly affair
Legal practitioners must have extensive computer knowledge
Need to produce authentic and convincing evidence

What is Cryptography? The Use Of Cryptography In Hacking.

Introduction to Cryptography:- Cryptography is the science of protecting secrets. As a result, it’s designed to make it impossible for an unauthorized party (like a hacker) to gain access to the protected data. While early encryption algorithms had significant flaws and were easily broken, the state of the art in encryption has gotten a lot better. That being said, cryptography can be broken under the right circumstances. The first step in breaking cryptography is identifying the cryptographic algorithm in use. Cryptography is the art of converting text into another form for secret transmission and reception. It works by converting plain text into cipher text using some encryption algorithm at the sender’s side and converting ciphertext into plain text at the receiver’s. Cryptography is used to provide confidentiality, integrity, authenticity and non-repudiation. With this information in hand, it’s time to start looking for an exploitable vulnerability. T...

What is Vishing? Tips for Spotting and Avoiding Vishing.

"When your phone rings, it’s sometimes hard to know who’ll be on the other end. It might be someone vishing. " Vishing, a combination of ‘voice’ and ‘phishing,’ is a phone scam designed to get you to share personal information. Here's what to know about vishing attacks and how to help protect yourself. What is Vishing? During a vishing phone call, a scammer uses social engineering to get you to share personal information and financial details, such as account numbers and passwords. The scammer might say your account has been compromised, claim to represent your bank or law enforcement, or offer to help you install software. Warning: It's probably malware. Vishing is just one form of phishing, which is any type of message — such as an email, text, phone call or direct-chat message — that appears to be from a trusted source, but isn’t. The goal is to steal someone's identity or money. It’s getting easier to contact more people, too. Scammers can place...

What is Armitage and how is it used.

What is Armitage? Armitage is a graphical user interface for the Metasploit Framework. At first glance, it may seem that Armitage is just a pretty front-end on top of Metasploit. That’s not quite true. Armitage is a scriptable red team collaboration tool. It has a server component to allow a team of hackers to share their accesses to compromised hosts. Starting Kali Linux The best way to start playing with Armitage is to download Kali Linux and run it in a virtual machine. For this guide, you should set your virtual machine to NAT networking. This is necessary because in a moment, I will ask you to download a target virtual machine and set it up. To login to Kali Linux, use the username root , password toor . To request an IP address via DHCP, type dhclient . To start X Windows, type startx . Use Java 1.7 Kali Linux ships with Java 1.6 and Java 1.7. Java 1.6 is the default though and for some people–this version of Java makes their menu...
