INTRODUCTION – SIEM Platforms
In fact, it has transformed into an exciting critical module: Security Information and Event Management (SIEM) platforms once again as a way and means of improving cybersecurity defenses and their enhancement. Meanwhile, this module will take you deep into SIEM platforms for you to learn some good and complete tricks about how they function, what their capabilities are, and how to implement them effectively.
New learning has practical and real-world applications, as this course would involve hands-on exercises and applications in various practical cases where students can practice their skills in threat detection, incident responses, and security analytics. Immense power lies in harnessing the SIEM capabilities, and your organization will be at an altogether better security posturing while you manage the dynamic nature of contemporary cyber threats with utmost confidence.

- Bias elimination
- Common sense (CORRECT)
- Generalization (CORRECT)
- Morals (CORRECT)
- Pattern identification
- Anomaly detection
3. A robust cybersecurity defense includes contributions from 3 areas, human expertise, security analytics and artificial intelligence. Which of these areas would contain the ability for abstraction?

- Artificial intelligence
- Security analytics
SIEM PLATFORMS GRADED ASSESSMENT

- True (CORRECT)
- False
2. For a SIEM, what are logs of specific actions such as user logins referred to?
- Logs
- Actions
- Events (CORRECT)
- Flows
3. Which of these describes the process of data normalization in a SIEM?
- Compresses incoming
- Indexes data records for fast searching and sorting (CORRECT)
- Removes duplicate records from incoming data
- Encrypts incoming data
4. When a data stream entering a SIEM exceeds the volume it is licensed to handle, what are three (3) ways the excess data is commonly handled, depending upon the terms of the license agreement? (Select 3)
- The data stream is throttled to accept only the amount allowed by the license (CORRECT)
- The data is processed and the license is automatically bumped up to the next tier.
- The excess data is dropped (CORRECT)
- The excess data is stored in a queue until it can be processed (CORRECT)
Partially correct!
5. Which five (5) event properties must match before the event will be coalesced with other events? (Select 5)
- Source Port
- Destination Port (CORRECT)
- Source IP (CORRECT)
- QID (CORRECT)
- Username (CORRECT)
- Destination IP (CORRECT)
Partially correct!
6. What is the goal of SIEM tuning?
- To get the SIEM to present all recognized offenses to the investigators
- To get the SIEM to sort out all false-positive offenses so only those that need to be investigated are presented to the investigators (CORRECT)
- To increase the speed and efficency of the data processing so license caps are never exceeded.
- To automatically resolve as many offenses as possible with automated actions
7. True or False. QRadar event collectors send all raw event data to the central event processor for all data handling such as data normalization and event coalescence.
- True
- False (CORRECT)

- People
- Process (CORRECT)
- Technology
- None of the above
9. True or False. There is a natural tendency for security analysts to choose to work on cases that they are familiar with and to ignore those that may be important but for which they have no experience.

CONCLUSION – SIEM Platforms
Thus, this entire module has imparted a robust understanding of Security Information and Event Management (SIEM) platforms and their inevitability in fortifying cybersecurity defenses. Participants have undergone both hands-on learning as well as real-life application in sharpening their artisanal craft in using the SIEM in detection, response, and security analytics.
Participants will enact the equipped knowledge to address the increasing complexities of the modern cyberspace cyberthreat landscape and protect the assets of organizations. By increasingly automatic implementations of code and expert usage of SIEM, participants will be basaltic in the future towards fortifying an imperfect but resilient adaptive posture against the spectrums of shifting cyberthreats.
