The log in the exhibit is generated by a firewall. It shows a deny action taken on TCP traffic, specifying the source and destination addresses and ports, which is characteristic of firewall logs. Firewalls are designed to control incoming and outgoing network traffic based on predetermined security rules, and this log entry reflects the enforcement of such a rule.

Stealthwatch is the technology that an engineer should use to fetch logs from a proxy server and generate actual events based on the data received. Cisco Secure Network Analytics, formerly known as Stealthwatch, provides the capability to configure proxy server logs so that the Flow Collector can receive the information.The Stealthwatch Management Console then displays this information on the Flow Proxy Records page, which includes URLs and application names of the traffic inside a network going through the proxy server1.

In Wireshark, to filter traffic for a specific LAN, the correct syntax usesip.src==andip.dst==to specify the source and destination IP addresses. The/16denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range.This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic.Reference:: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.

Wireshark is a widely-used network protocol analyzer that allows users to capture and interactively browse the traffic running on a computer network.It provides full packet capture capabilities, enabling detailed analysis of network traffic.Reference:: This is supported by the CBROPS course materials, which discuss security monitoring and the analysis of network traffic, including full packet capture tools like Wireshark

For high availability and responsiveness, especially where milliseconds of latency are critical, an engineer must analyze the network's performance in detail. Total throughput on the interface of the router will provide information on the bandwidth and traffic load, which is essential for understanding if the network can handle the current and projected traffic without delays. NetFlow records are crucial for this analysis as they provide data about the traffic flow across the network, which helps in identifying patterns, peak usage times, and types of traffic.This information is vital for making informed decisions to optimize traffic movement and minimize latency123.

The exhibit shows a UNIX command being used to filter data from an Apache access log file. The use of ''cat'' to display the content of the log file, ''grep'' to filter specific IP addresses, and ''cut'' to organize the output are all indicative of operations performed on a UNIX-based system. Additionally, the structure of the logs (GET requests) aligns with the format typically found in Apache server logs.Reference:= The Cisco Cybersecurity source documents or study guide are not directly referenced here as I need to search for specific content related to this question.

A load balancer is the correct technology to implement a solution that makes routing decisions based on HTTP header, uniform resource identifier (URI), and SSL session ID attributes.Load balancers can inspect incoming traffic and make routing decisions to distribute the traffic across multiple servers based on various attributes, including the ones mentioned, to ensure optimal resource use and efficient traffic management12.

In the context of NIST SP800-61, a precursor is an event that indicates the potential occurrence of an incident. When an organization adjusts its security stance in response to online threats made by a known hacktivist group, the initial event---the threats---would be considered a precursor.It is an indication of a potential future attack or security incident34.
