Performance evaluation of the proposed architecture is to verify our network forensics cloud-based system performs well enough as compared to the previously published model. The setup of measuring the performance impact on the running VMM manages all VMs in the cloud environment with network forensics. The process consumes computational and power resources to evaluate the model performance, communicate resources that would capture, aggregate and analyse, and transfer network traffic.

In the experiment, the proposed model architecture intended to quantify the performance matrix by comparing both the scenarios: (i) without network forensics and (ii) with network forensics (shown in Figure 2.4).

The performance measurement was done by setting the tune of the host system, as well as mention the crucial software specification of the hosts, described below:

 System Software: Linux Ubuntu 18.04;

 Application Software: OpenNebula and NetworkMiner;

 System Specification: x64 2.4GHz Octa-Core 7th Generation CPU with 32GB RAM connected via highly powerful ether-net connectivity up to Gigabit.

Evaluate almost 8 VMs parallel with network forensics on a single virtual machine monitor, VMs hosts a web-based service interface that runs tasks as a computationally intensive. This web-based service interface calculates both the great common divers, for example, with or without network forensics, output results show in Figure 2.4. Iteratively calculate the request of cloud users to call a function over several times. Moreover, users’ web services and NetworkMiner analysis run a separate interface.

Figure 2.4 Measurement of the performance of network forensics while running cloud infrastructure systems.

 Call Function: More than 2,800 times with minimum 20 concurrent requests;

 The time it takes to calculate the call function of cloud users is less than 2 minutes;

 The average performance of VMs is almost 89%;

 Average performance reduction between 3% to 18%.

Recently, cloud service provides offered Forensics-as-a-Service. Similar to the other cloud services, FaaS is a business service model for digital investigators. One is the addition of cloud resources for the analysis of forensics data by cloud users, and the second is the most prominent aspect that, not account for VMM plus network forensics cloud-based system. Estimate the sets of forensics transferred data to the accumulator that aggregate and then the analyzation process-layer.

In the next section, we have taken a real-world scenario of cloud security impact on M2M communication and how we can utilize the cloud application in the fourth industrial revolution.
