Q: Which of the following statements correctly describes logs? Select two answers.
- A log is used as a formal guide to incident response.
- Security professionals use logs to automate tasks.
- A business might log each time an employee accesses web-based services.
- Logs helps identify vulnerabilities and potential security breaches.
Explanation: The use of logs as a formal guide to incident response is not common, even though they may give useful information during investigations of incidents. When it comes to security experts, logs are not mainly used for the goal of automating operations; rather, they are utilized for the purposes of monitoring and analysis.
Q: Which of the following tasks can be performed using SIEM tools? Select
three answers.
- Notifying authorities of illegal activity
- Performing incident analysis
- Proactively searching for threats
- Providing alerts for specific types of risks
Explanation: To detect and investigate possible security issues, security event management (SIEM) solutions gather and analyze data on security events.SIEM technologies can do monitoring and analysis in real-time, allowing them to identify and react to ever-evolving threats before they can cause any damage. To notify security personnel about possible dangers or anomalies, security information, and event management (SIEM) technologies create alerts and notifications based on established criteria and the correlation of security events.
Q: A cybersecurity analyst needs to collect data from multiple places to
analyze filtered events and patterns. What type of tool should they use?
- network protocol analyzer (packet sniffer)
- Playbook
- Security information and event management (SIEM)
- Linux operating system
Explanation: A Security Information and Event Management (SIEM) tool is the kind of technology that a cybersecurity analyst needs to utilize to gather data from a variety of sources, evaluate events that have been filtered, and identify trends. The purpose of security information and event management (SIEM) systems is to collect and correlate log data from a wide variety of sources throughout an organization's network. This provides analysts with the ability to monitor and evaluate security occurrences live.
Q: Fill in the blank: A security professional uses a _____ as a manual to
guide operational activities.
- spreadsheet
- review
- playbook
- toolkit
Explanation: To provide direction for operational tasks, a security expert will employ a playbook as a guidebook. It is possible to react to particular security events or operational chores in a way that is both organized and consistent by using playbooks, which offer predetermined processes and stages.
Q: As a security analyst, you are tasked with auditing your organization’s
network to identify security-related issues. How might a network protocol
analyzer (packet sniffer) help you perform this task?
- By removing malware and viruses from the network
- By automating tasks that reduce human error
- By simulating attacks on connected devices
- By capturing and analyzing data traffic on the network
Explanation: Through the process of collecting packets and analyzing their contents, network protocol analyzers can intercept and log network traffic. Security analysts can scan network communications, recognize anomalous or suspicious activity, detect efforts to gain unauthorized access, and investigate possible security vulnerabilities as a result of this. When it comes to monitoring network activity and discovering security-related vulnerabilities during audits, this functionality is very necessary.
Q: What are some key benefits of programming languages? Select all that
apply.
- They reduce the risk of human error.
- They complete tasks faster than if working manually.
- They are used to design security policies.
- They can be used to create a specific set of instructions for a computer to execute tasks.
Explanation: The use of programming languages makes it possible to carry out activities in a precise and consistent manner, hence lowering the chance of mistakes that may arise when using manual techniques. Written in programming languages, computer programs can automate repetitive operations and execute calculations at a far quicker rate than people can manually. The creation of a particular set of instructions that a computer may employ to carry out tasks is possible with their help. By enabling developers to express instructions that computers can comprehend and carry out, programming languages make it possible for developers to create apps and systems that are quite complicated.
Q: Fill in the blank: Linux relies on a(n) _____ as the primary user
interface.
- dashboard
- ciphertext
- error log
- command line
Explanation: The command line is the principal user interface that Linux uses instead of other interfaces.
Q: Fill in the blank: A database is a _____ of organized data stored in a
computer system.
- collection
- frame
- model
- visualization
Explanation: The collection of data that is structured and saved in a computer system is referred to as a database.
Q: What are some key benefits of using Python to perform security tasks?
Select all that apply.
- It simplifies repetitive tasks.
- It makes static data more dynamic.
- It is designed for high levels of accuracy.
- It helps security professionals be more accurate.
Explanation: The compact syntax and rich library support of Python make it possible to automate repetitive security activities, hence minimizing the amount of human labor required.When it comes to building and running security scripts and programs, Python's clarity and simplicity of use help to make the process more accurate.
Q: A cybersecurity analyst is tasked with proactively searching for threats
and performing incident analysis. What type of tool should they use?
- Security information and event management (SIEM)
- Linux operating system
- Structured Query Language (SQL)
- Chain of custody playbook
Explanation: SIEM, which stands for security information and event management, is the instrument that a cybersecurity analyst has to make use of to proactively look for risks and carry out incident analysis. The purpose of security information and event management (SIEM) solutions is to gather, aggregate, and analyze data on security events from a variety of sources throughout an organization's network. This gives analysts the ability to identify and react to possible threats in real-time.
Q: Fill in the blank: A security team uses a _____ to help them document
organizational processes from beginning to end.
- graph
- playbook
- legend
- toolkit
Q: As a security analyst, you are monitoring network traffic and detect a
large number of failed login attempts. Which of the following tools would help
you investigate this incident? Select two answers.
- An antivirus software
- A cryptographic encoder
- An intrusion detection system (IDS)
- A network protocol analyzer (packet sniffer)
Explanation: IDS systems are responsible for monitoring network traffic to identify any trends or activities that may be indicative of possible security breaches, such as unsuccessful attempts to log in. Agents can evaluate the contents of packets, including unsuccessful login attempts, to ascertain the source of the packets and the possible effect they may have. Packet sniffers are devices that intercept and analyze network traffic.
Q: A security team wants to examine logs to understand what is occurring
within their systems. Why might they choose Linux to perform this task? Select
two answers.
- It is open source.
- It is an efficient programming language.
- It allows for text-based commands by users.
- It is proprietary.
Explanation: Given that Linux is an open-source operating system, security teams have access to the source code, can make modifications to it as required, and can depend on a huge community for support and development. In Linux, a sophisticated command-line interface (CLI) is available, which allows security teams to easily traverse through logs, search for particular items, and do analysis by using a variety of text-based commands.
