OPSEC is a 5-step process that helps in developing protection mechanisms in order to safeguard sensitive information and preserve essential secrecy. The OPSEC process has five steps, which are as follows: 1.Identification of Critical Information: This step includes identifying information vitally needed by an adversary, which focuses the remainder of the OPSEC process on protecting vital information, rather than attempting to protect all classified or sensitive unclassified information. 2.Analysis of Threats: This step includes the research and analysis of intelligence, counterintelligence, and open source information to identify likely adversaries to a planned operation. 3.Analysis of Vulnerabilities: It includes examining each aspect of the planned operation to identify OPSEC indicators that could reveal critical information and then comparing those indicators with the adversary's intelligence collection capabilities identified in the previous action. 4.Assessment of Risk: Firstly, planners analyze the vulnerabilities identified in the previous action and identify possible OPSEC measures for each vulnerability. Secondly, specific OPSEC measures are selected for execution based upon a risk assessment done by the commander and staff. 5.Application of Appropriate OPSEC Measures: The command implements the OPSEC measures selected in the assessment of risk action or, in the case of planned future operations and activities, includes the measures in specific OPSEC plans.

Wireshark is an open source protocol analyzer that can capture traffic in real time. Wireshark is a free packet sniffer computer application. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Wireshark is very similar to tcpdump, but it has a graphical front-end, and many more information sorting and filtering options. It allows the user to see all traffic being passed over the network (usually an Ethernet network but support is being added for others) by putting the network interface into promiscuous mode.
Wireshark uses pcap to capture packets, so it can only capture the packets on the networks supported by pcap. It has the following features:
Data can be captured "from the wire" from a live network connection or read from a file that records the already-captured packets.
Live data can be read from a number of types of network, including Ethernet, IEEE 802.11, PPP, and loopback.
Captured network data can be browsed via a GUI, or via the terminal (command line) version of the utility, tshark.
Captured files can be programmatically edited or converted via command-line switches to the "editcap" program.
Data display can be refined using a display filter. Plugins can be created for dissecting new protocols.
Answer option C is incorrect. Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures.
Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP).
Answer option D is incorrect. NetWitness is used to analyze and monitor the network traffic and activity.
Answer option A is incorrect. Netresident is used to capture, store, analyze, and reconstruct network events and activities.

quantitative
Explanation:
Quantitative risk analysis is a process to assess the probability of achieving particular project objectives, to quantify the effect of risks on the whole project objective, and to prioritize the risks based on the impact to the overall project risk. The quantitative risk analysis process analyzes the effect of a risk event deriving a numerical value. It also presents a quantitative approach to build decisions in the presence of uncertainty. The inputs for quantitative risk analysis are as follows: Organizational process assets Project scope statement Risk management plan Risk register Project management plan
