1. Policy and Procedure Development.
2. Evidence Assessment.
3. Evidence Acquisition.
4. Evidence Examination.
5. Documenting and Reporting.

How should you proceed if your network forensic investigation involves other companies?

How should you proceed if your network forensic investigation involves other companies? ANS: As with all investigations, keep preservation of evidence in mind. Your investigation might turn up other companies that have been compromised.

What is the difference between digital forensics and network forensics?

Network forensics is a branch of digital forensics. That said; it is significantly different from conventional forensic investigations. Unlike other areas of digital forensics, network forensic investigations deal with volatile and dynamic information. Disk or computer forensics primarily deals with data at rest.

What are network forensics tools?

Sniffing and analyzing tools help in analyzing network problems, detecting exploitation attempts isolating exploited systems, and monitoring system usage, etc.

What is the first step in a computer forensics investigation?

The first step in any forensic process is the validation of all hardware and software, to ensure that they work properly.

What are the six phases of the forensic investigation process?

What are the six phases of the forensic investigation process? This model was the base fundament of further enhancement since it was very consistent and standardized, the phases namely: Identification, Preservation, Collection, Examination, Analysis and Presentation (then a pseudo additional step: Decision).

Where is network forensics used?

Usually there are three types of people who use digital evidence from network forensic investigations: police investigators, public investigators, and private investigators. The following are some examples: Criminal prosecutors. Incriminating documents related to homicide, financial fraud, drug-related records.

How to prepare for a network forensic investigation?

Here are three things you can do: 1 Put a process in place. For network forensic investigators to do their work, there need to be log and capture files for them to examine. 2 Make a plan. Incident management planning will help to respond to and mitigate the effects of an attack. 3 Acquire the talent.

What’s the difference between network forensics and intrusion detection?

Network forensics is closely related to network intrusion detection: the difference is the former is legal-focused, and the latter is operations-focused. Network forensics is described as: “Traditionally, computer forensics has focused on file recovery and filesystem analysis performed against system internals or seized storage devices.

How is network forensics different from digital forensics?

Unlike digital forensics, network forensics are more difficult to carry out as data is often transmitted across the network and then lost; in computer forensics data is more often kept in disk or solid state storage making it easier to obtain.

How is network forensics used in cyber attacks?

Network forensics aim at finding out causes and impacts of cyber attacks by capturing, recording, and analyzing of network traffic and audit files [75 ]. NFA helps to characterize zero-day attacks and has the ability to monitor user activities, business transactions, and system performance.
