What is the name of the suspected malicious filecaptured by keyword process.executable at 11:04 PM?

Answer:

Explanation:
See the solution in Explanation.
Explanation:
To identify the name of the suspected malicious file captured by the keyword process.executable at11:04 PM onAugust 19, 2024, follow these detailed steps:
Step 1: Access the Alert Bulletin
* Locate the alert file:
* Access thealerts folderon your system.
* Look for the file named:
* Open the file:
* Use a PDF reader to examine the contents.
Step 2: Understand the Alert Context
* The bulletin indicates that the network was compromised at around11:00 PM.
* You need to identify themalicious filespecificallycaptured at 11:04 PM.
Step 3: Access System Logs
* Use yourSIEMorlog management systemto examine recent logs.
* Filter the logs to narrow down the events:
* Time Frame:August 19, 2024, from11:00 PM to 11:10 PM.
* Keyword:process.executable.
Example SIEM Query:
index=system_logs
| search "process.executable"
| where _time between "2024-08-19T23:04:00" and "2024-08-19T23:05:00"
| table _time, process_name, executable_path, hash
Step 4: Analyze Log Entries
* The query result should show log entries related to theprocess executablethat was triggered at11:04 PM
.
* Focus on entries that:
* Appear unusual or suspicious.
* Match known indicators from thealert bulletin (alert_33.pdf).
Example Log Output:
_time process_name executable_path hash
2024-08-19T23:04 evil.exe C:UsersPublicevil.exe 4d5e6f...
Step 5: Cross-Reference with Known Threats
* Check the hash of the executable file against:
* VirusTotalor internal threat intelligence databases.
* Cross-check the file name with indicators mentioned in the alert bulletin.
Step 6: Final Confirmation
* The suspected malicious file captured at11:04 PMis the one appearing in the log that matches the alert details.
The name of the suspected malicious file captured by keyword process.executable at 11:04 PM is: evil.exe Step 7: Take Immediate Remediation Actions

NEW QUESTION # 140
Which of the following is the PRIMARY benefit of compiled programming languages?

  • A. Ability to change code in production
  • B. Streamlined development
  • C. Fasterapplication execution
  • D. Flexibledeployment

Answer: C

Explanation:
Theprimary benefit of compiled programming languages(like C, C++, and Go) isfaster execution speed because:
* Direct Machine Code:Compiled code is converted to machine language before execution, eliminating interpretation overhead.
* Optimizations:The compiler optimizes code for performance during compilation.
* Performance-Intensive Applications:Ideal for system programming, game development, and high- performance computing.
Other options analysis:
* A. Streamlined development:Compiled languages often require more code and debugging compared to interpreted languages.
* C. Flexible deployment:Interpreted languages generally offer more flexibility.
* D. Changing code in production:Typically challenging without recompilation.
CCOA Official Review Manual, 1st Edition References:
* Chapter 10: Secure Coding Practices:Discusses the benefits and challenges of compiled languages.
* Chapter 8: Software Development Lifecycle (SDLC):Highlights the performance benefits of compiled code.


NEW QUESTION # 141
Which type of middleware is used for connecting software components thatarewritten in different programming languages?

  • A. Object-oriented middleware
  • B. Message-oriented middleware
  • C. Transaction processing middleware
  • D. Remote procedure call middleware

Answer: A

Explanation:
Object-oriented middlewareis used toconnect software components written in different programming languagesby:
* Language Interoperability:Enables objects created in one language to be used in another, typically throughCORBA (Common Object Request Broker Architecture)orDCOM (Distributed Component Object Model).
* Distributed Systems:Facilitates communication between objects over a network.
* Platform Independence:Abstracts the underlying communication protocols.
* Example Use Case:A Java application calling methods on a C++ object using CORBA.
Other options analysis:
* A. Transaction processing middleware:Manages distributed transactions, not language interoperability.
* B. Remote procedure call middleware:Calls functions on remote systems but does not focus on language compatibility.
* C. Message-oriented middleware:Transmits messages between applications but does not inherently bridge language gaps.
CCOA Official Review Manual, 1st Edition References:
* Chapter 9: Middleware Technologies:Discusses various types of middleware and their roles.
* Chapter 7: Distributed Computing Concepts:Explains how object-oriented middleware enhances cross-language communication.


NEW QUESTION # 142
An organization moving its payment card system into a separate location on its network (or security reasons is an example of network:

  • A. centricity.
  • B. encryption.
  • C. segmentation.
  • D. redundancy.

Answer: C

Explanation:
The act of moving apayment card system to a separate network locationis an example ofnetwork segmentationbecause:
* Isolation for Security:Segregates sensitive systems from less secure parts of the network.
* PCI DSS Compliance:Payment card data must be isolated to reduce thescope of compliance.
* Minimized Attack Surface:Limits exposure in case other parts of the network are compromised.
* Enhanced Control:Allows for tailored security measures specific to payment systems.
Other options analysis:
* A. Redundancy:Involves having backup systems, not isolating networks.
* C. Encryption:Protects data but does not involve network separation.
* D. Centricity:Not a recognized concept in network security.
CCOA Official Review Manual, 1st Edition References:
* Chapter 7: Network Segmentation and Isolation:Emphasizes segmentation for protecting sensitive data.
* Chapter 9: PCI Compliance Best Practices:Discusses network segmentation to secure payment card environments.


NEW QUESTION # 143
In which cloud service model are clients responsible for regularly updating the operating system?

  • A. Software as a Service (SaaS)
  • B. Platform as a Service (PaaS)
  • C. Infrastructure as a Service (laaS)
  • D. Database as a Service (OBaaS)

Answer: C

Explanation:
In theIaaS (Infrastructure as a Service)model, clients are responsible formanaging and updating the operating systembecause:
* Client Responsibility:The provider supplies virtualized computing resources (e.g., VMs), but OS maintenance remains with the client.
* Flexibility:Users can install, configure, and update OSs according to their needs.
* Examples:AWS EC2, Microsoft Azure VMs.
* Compared to Other Models:
* SaaS:The provider manages the entire stack, including the OS.
* DBaaS:Manages databases without requiring OS maintenance.
* PaaS:The platform is managed, leaving no need for direct OS updates.
