Forensics in a Security Operations process refers to collecting raw data needed to complete the detailed analysis of an investigation. Forensic analysis is a crucial step in identifying, investigating, and documenting the cause, course, and consequences of a security incident or violation. Forensic analysis involves various techniques and tools to extract, preserve, analyze, and present evidence in a structured and acceptable format. Forensic analysis can be used for legal compliance, auditing, incident response, and threat intelligence purposes. References:

Multiple policies, no policy reconciliation tools: Sequential traffic analysis (stateful inspection, application control, intrusion prevention system (IPS), anti-malware, etc.) in traditional data center security solutions requires a corresponding security policy or profile, often using multiple management tools. The result is that your security policies become convoluted as you build and manage a firewall policy with source, destination, user, port, and action; an application control policy with similar rules; and any other threat prevention rules required. Multiple security policies that mix positive (firewall) and negative (application control, IPS, and anti-malware) control models can cause security holes by missing traffic and/or not identifying

To maximize the use of a network address, the administrator should use the subnet that can accommodate the required number of hosts with the least amount of wasted IP addresses. The subnet mask determines how many bits are used for the network portion and the host portion of the IP address. The more bits are used for the network portion, the more subnets can be created, but the fewer hosts can be assigned to each subnet. The formula to calculate the number of hosts per subnet is

2(32−n)−2

, where

n

is the number of bits in the network portion of the subnet mask. For example, a /30 subnet mask has 30 bits in the network portion, so the number of hosts per subnet is

2(32−30)−2=2

A /25 subnet mask has 25 bits in the network portion, so the number of hosts per subnet is

2(32−25)−2=126

The subnet 192.168.6.0/25 can accommodate 126 hosts, which is enough for the network with 120 hosts. The subnet 192.168.6.168/30 can only accommodate 2 hosts, which is not enough. The subnet 192.168.6.160/29 can accommodate 6 hosts, which is also not enough. The subnet 192.168.6.128/27 can accommodate 30 hosts, which is enough, but it wastes more IP addresses than the /25 subnet. Therefore, the best option is B. 192.168.6.0/25. References:
