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.

When a system is overwhelmed with alerts, designing criteria for reviewing alerts can help prioritize and manage them more effectively. This approach allows for a structured review process that can distinguish between false positives, false negatives, and legitimate alerts, reducing the overall number of alerts that require attention3.

References := The strategy of designing criteria for reviewing alerts is recommended in cybersecurity best practices to manage alert fatigue and improve the efficiency of security operations3.

 A web proxy is the technology used to block a user’s HTTP connection to a malicious site according to configured policy. It acts as an intermediary between users and the internet, enforcing security policies and preventing access to harmful sites by inspecting and managing web traffic.

The regular expression that matches both “color” and “colour” is colo?ur. In this expression, the ? denotes that the preceding character u is optional, meaning it may appear zero or one time. This allows the expression to match both the American spelling “color” and the British spelling “colour”.

References := Understanding regular expressions is fundamental in various computing tasks, including cybersecurity operations. The Cisco Cybersecurity Operations Fundamentals (CBROPS) material covers the use of regular expressions for searching through logs and data, which is a critical skill for a cybersecurity analyst.

The exhibit shows “HKEY_LOCAL_MACHINE,” which is a Windows Registry hive. The registry is a database used to store low-level settings for the operating system and for applications that opt to use the registry. The other options are not related to the exhibit, as they are either a part of the Windows Certificate Manager, a naming convention for Windows PowerShell commands, or a component of the Windows Services Manager. References := Cisco Cybersecurity

 When a server is experiencing high CPU and memory load, the first step is to identify the processes that are consuming the most resources. The command “ps -ef” is used to display information about all the running processes, including their IDs, memory and CPU usage, and the commands that started them. This allows the engineer to pinpoint which processes are responsible for the high load and take appropriate action, such as terminating unnecessary processes or optimizing resource usage345. References: Various resources on server management and troubleshooting recommend using the “ps -ef” command as a starting point for investigating high resource usage on servers

Inline traffic interrogation analyzes traffic in real time and has the ability to prevent certain traffic from being forwarded Traffic mirroring doesn't pass the live traffic instead it copies traffic from one or more source ports and sends the copied traffic to one or more destinations for analysis by a network analyzer or other monitoring device

 CIA stands for confidentiality, integrity, and availability, which are the three main objectives of information security. Confidentiality means protecting the information from unauthorized access or disclosure. Integrity means ensuring the information is accurate and consistent, and preventing unauthorized modification or deletion. Availability means ensuring the information and systems are accessible and usable by authorized users when needed. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1.0/CSCU-LP-CBROPS-V1-028093.html (Module 2: Security Concepts, Lesson 2.1: Security Principles)

The exhibit shows an HTTP GET request with a parameter that includes; /bin/sh -c id.

This indicates a command injection attempt, where the attacker is trying to execute shell commands on the server.

Command injection vulnerabilities allow an attacker to execute arbitrary commands on the host operating system via a vulnerable application.

The use of/bin/shand the-cflag is typical in command injection exploits to run shell commands, such asid, which returns user identity information.
