Network Forensics

Comprehension

What is Network Forensics?

Network Forensics is the investigation of network traffic and information gathered in transit between computer systems. It has the ability to reveal the source and scope of an attack.

Understanding Protocols

Understanding network protocols is vital to recognise attack trends to monitor network events.

Proprietary Tools

We have tools and experts helping in investigating network attacks and providing conclusions.

Significance

Benefits of Network Forensics

CryptoMize knows the importance of Network Forensics, including the huge amount of data flow and the complexity of Internet protocols. Capturing network traffic is simple in theory but challenging in practise.
  • Tracing network traffic takes time and effort.It may be difficult to get all the network data. This necessitates a free recording medium
  • Network Forensics is required in order to identify the kind of network attack and track down the perpetrator
  • If a well structured investigation method is used, Network Forensics aids in determining the causes of network failures.

INITIAL POINTS

Sources of Network Forensics

In order to rectify, you must first identify the problem, then collect and analyse data, decide on the appropriate repair approach and put it into action.

Generally, Examination of two types of sources is done in the field of Network Forensics.

Full-Packet Data Capture

Full-Packet Capture has the advantage of identifying the content of data being sent, as well as its meaning and value.

Log files

They are used when suspicious behaviour is identified. Choosing a packet-capture to collect traffic from impacted devices is critical.

Enumeration

95%

EavesDropping

Unlawful method of monitoring unprotected links to get personal data

IP Spoofing

Allows unrestricted access to computers by sending messages using IP addresses

Packet Sniffing

An act of collecting network traffic to get sensitive information such as passwords

Enumeration

Process of collecting data about a network that may be used to attack it

ASSISTANCE

How can CryptoMize help?

The capacity to comprehend the data contained in log and capture files, as well as to detect malicious behaviour within the data, is a specialised talent that necessitates extensive knowledge of network and application protocol architecture.
Before an attack occurs, businesses can take precautions to ensure that network-based forensic investigations are successful. In order to assist you, CryptoMize can perform the three actions listed below.

Capturing your Packets

What is it?

Packet Sniffing is the term used to describe the act of gathering data packets from across a computer network. It's the same as hacking into a phone network's wires and stealing.

Packet

In a computer network, a packet is the smallest unit of communication that may be sent. A packet may also be referred to as a block, a segment, a datagram, or simply a datagram.

Application

When packet data is being transmitted across a network, packet sniffing techniques are used to detect and monitor the data as it moves across the network.

What we do

CryptoMize’s Network Forensic Investigators monitor and verify your network traffic to investigate the network traffic to figure out potential threats during the investigation.

Detecting Threats In Your Network Traffic

  • ✓ Network Threats are unlawful or destructive activities that attempt to take advantage of network flaws.
  • ✓ Networks are also targeted by malicious attacks in order to gain unauthorised access and manipulate them for their own gain.
  • ✓ Threat Detection is one of the three fundamental cybersecurity responsibilities, along with prevention and response.
  • ✓ Risk reduction requires prevention, yet determined opponents will always defeat prevention.
  • ✓ CryptoMize offers Network Threat Detection to help with the investigation process.
Detecting Threats In Your Network Traffic
Analysing logs

Scanning Your Network Logs

Almost all information technology systems generate a log, which records all system activities. Computer platforms (servers, appliances, and smartphones), operating systems (Windows, Linux, iOS), and programmes (client/server, web apps, cloud-based utilities) all generate logs.
  • A Network Log is a file in an application that keeps track of what occurred during the program's execution. It maintains track of objects accessed by users and processes, as well as authentication attempts and other events.
  • A mistake, a warning, or an instructive action may all be characterised as an event. To meet various application requirements, the application designer typically defines the format and data in a log, and then the application developer implements it.
  • Logs can be incredibly long and include a tremendous deal of information at times, so be careful when reading them. In an attempt to conserve as many lines as possible, the lines would become incoherent if they were all kept.

FAQ'S

Our Featured Service Offering Categories

Network Forensics is the technique of capturing, recording, and analysing network packets to identify the source of network security threats.

Following are the seven stages of a Network Forensics Investigation:

  • Identification
  • Preservation
  • Collection
  • Examination
  • Analysis
  • Presentation
  • Incident Response
By collecting, recording, and analysing network traffic and audit files, Network Forensics aims to determine the causes and consequences of cyber attacks Network Forenisc Analysis is capable of monitoring user activity, business transactions, and system performance as well as helping to classify zero-day attacks.
Administrators may use Network Forensic Analysis Tools (NFATs) to monitor their network for unusual activity, conduct forensic analysis, and obtain a comprehensive picture of their environment. It focuses on SilentRunner, NetIntercept, and NetDetector to have a better understanding of the tool.
Capturing and analysing packets necessitates the use of network sniffing and packet analysis tools. Wireshark, Aircrack-ng, WebScarab, ngrep, NetworkMiner, Kismet, and eMailTrackerPro are some of the tools mentioned. The purpose of network scanning is to determine which hosts are active in the network.
Web server logs, for example, may be utilized to demonstrate when (or whether) a suspect viewed criminal activity-related material. Email accounts may frequently include valuable evidence; however, since email headers are readily forged, Network Forensics can be used to establish the precise origin of damning information. By extracting user account information from network traffic, Network Forensics may also be used to determine who is using a certain machine.
