Important Eccouncil 212-82 Exam Questions

Answer: B

Explanation:

Dynamic Baseline Establishment:

Machine learning algorithms can analyze vast amounts of network traffic data over an extended period, such as a month, to understand normal and abnormal patterns dynamically.

Real-Time Detection and Mitigation:

By leveraging machine learning, the system can continuously learn and adapt to new traffic patterns, reducing false positives and ensuring accurate real-time threat detection and mitigation.

Reduction of False Positives:

A machine learning-based approach can distinguish between benign anomalies and actual threats by considering context, historical data, and behavioral patterns, thereby minimizing false positives.

Handling Evolving Threats:

The dynamic nature of machine learning allows the baseline to evolve as new types of traffic and threats emerge, ensuring that the security system remains effective against both known and unknown threats.

Using machine learning to establish a dynamic baseline is an effective strategy for NetSafe Corp to maintain robust network security and respond to threats promptly.

Answer: C

Explanation:

Availability is the information security element that ensures that Stella's transaction status is immediately reflected in her bank account in this scenario. Information security is the practice of protecting information and information systems from unauthorized access, use, disclosure, modification, or destruction. Information security can be based on three fundamental principles: confidentiality, integrity, and availability. Confidentiality is the principle that ensures that information is accessible only to authorized parties and not disclosed to unauthorized parties. Integrity is the principle that ensures that information is accurate, complete, and consistent and not altered or corrupted by unauthorized parties. Availability is the principle that ensures that information and information systems are accessible and usable by authorized parties when needed. In the scenario, Stella purchased a smartwatch online using her debit card. After making payment for the product through the payment gateway, she received a transaction text message with a deducted and available balance from her bank. This means that her transaction status was immediately reflected in her bank account, which indicates that availability was ensured by her bank's information system.

Answer: C

Explanation:

3 is the number of files present in the folder in the above scenario. A RAT (Remote Access Trojan) is a type of malware that allows an attacker to remotely access and control a compromised system or network. A RAT can be used to steal sensitive data, spy on user activity, execute commands, install other malware, etc. To initiate a remote connection using thief client, one has to follow these steps:

Navigate to the thief folder located at Z:\CCT-Tools\CCT Module 01 Information Security Threats and Vulnerabilities\Remote Access Trojans (RAT)\Thief of Attacker Machine-1.

Double-click on thief.exe file to launch thief client.

Enter 20.20.10.26 as IP address of server.

Enter 1234 as port number.

Click on Connect button.

After establishing connection with server, click on Browse button.

Navigate to Desktop folder on server.

Count number of files present in folder.

The number of files present in folder is 3, which are:

Answer: C

Explanation:

For NexaCorp to effectively monitor and analyze system logs, implementing a Security Information and Event Management (SIEM) system is the optimal approach:

SIEM Overview: SIEM systems collect, normalize, and analyze log data from various sources in real-time.

Benefits:

Centralization: Aggregates logs from all systems into a single platform.

Correlation: Identifies patterns and correlates events from different sources to detect anomalies.

Implementation Steps:

Select a SIEM Solution: Choose a suitable SIEM tool (e.g., Splunk, ELK Stack, QRadar).

Integration: Configure the SIEM to collect logs from all relevant systems.

Alerting and Reporting: Set up alerts for suspicious activities and generate periodic reports.

SIEM Basics: Link

Answer: B

Explanation:

Isolation of VMs:

OS virtualization provides isolation between virtual machines (VMs). Each VM operates independently with its own operating system and resources. This isolation ensures that a security breach in one VM does not affect other VMs on the same physical host.

Containment of Attacks:

In the event of a compromise, the attack is contained within the affected VM, minimizing the risk of lateral movement and infection of other VMs.

Resource Management:

Hypervisors enforce strict resource allocation policies, preventing VMs from accessing resources allocated to other VMs. This enhances security by limiting the scope of any potential attack.

Hypervisor Security:

The security of the hypervisor itself is critical. Modern hypervisors implement robust security measures to prevent VM escape and other attacks that could compromise the host or other VMs.

By leveraging OS virtualization for isolation, organizations can significantly improve their security posture, reducing the risk of widespread breaches.
