Eccouncil 212-82 Exam Questions

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.

PCI-DSS requirement no 5.3 is the PCI-DSS requirement that is demonstrated in this scenario. PCI-DSS (Payment Card Industry Data Security Standard) is a set of standards that applies to entities that store, process, or transmit payment card information, such as merchants, service providers, or payment processors. PCI-DSS requires them to protect cardholder data from unauthorized access, use, or disclosure. PCI-DSS consists of 12 requirements that are grouped into six categories: build and maintain a secure network and systems, protect cardholder data, maintain a vulnerability management program, implement strong access control measures, regularly monitor and test networks, and maintain an information security policy. PCI-DSS requirement no 5.3 is part of the category ''maintain a vulnerability management program'' and states that antivirus mechanisms must be actively running and cannot be disabled or altered by users, unless specifically authorized by management on a case-by-case basis for a limited time period. In the scenario, Ayden works from home on his company's laptop. During working hours, he received an antivirus software update notification on his laptop. Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel. This means that his company's laptop has an antivirus mechanism that is actively running and cannot be disabled or altered by users, which demonstrates PCI-DSS requirement no 5.3.

Strong Security:

EAP-TLS provides strong security by using certificate-based authentication. This ensures that both the client and server are authenticated before a connection is established.

Seamless User Experience:

Once the certificates are installed, the authentication process is seamless for the user, providing a balance between strong security and convenience.

Mitigating Risks:

EAP-TLS mitigates risks associated with weaker authentication methods, such as Pre-Shared Keys (PSKs), which can be shared or stolen.

Deployment and Management:

Although initial deployment and certificate management require effort, the long-term security benefits and user convenience outweigh the initial setup challenges.

Given the need for a balance between security and convenience, EAP-TLS is the best authentication method for Hotel Grande's Wi-Fi access.

Jane encountered a combination of social engineering tactics:

Spear Phishing:

CEO Impersonation Email: The initial email and the follow-up with the scanned image of the CEO's handwritten note are examples of spear phishing, where attackers target specific individuals with tailored messages to gain their trust and extract sensitive information.

Vishing:

'IT Support' Call: The phone call from the supposed 'IT support' representative asking Jane to download a 'security patch' is a form of vishing (voice phishing). This tactic involves using phone calls to trick victims into revealing sensitive information or performing actions that compromise security.

Social Engineering Techniques: SANS Institute Reading Room

Phishing and Vishing Explained: Norton Security

Managing and maintaining is the phase of firewall implementation and deployment in which Elliott monitored the firewall logs in the above scenario. A firewall is a system or device that controls and filters the incoming and outgoing traffic between different networks or systems based on predefined rules or policies. A firewall can be used to protect a network or system from unauthorized access, use, disclosure, modification, or destruction . Firewall implementation and deployment is a process that involves planning, installing, configuring, testing, managing, and maintaining firewalls in a network or system . Managing and maintaining is the phase of firewall implementation and deployment that involves monitoring and reviewing the performance and effectiveness of firewalls over time . Managing and maintaining can include tasks such as updating firewall rules or policies, analyzing firewall logs , detecting evolving threats or attacks , ensuring firewall security , addressing network issues , etc. In the scenario, Elliott was tasked with implementing and deploying firewalls in the corporate network of an organization. After planning and deploying firewalls in the network, Elliott monitored the firewall logs to detect evolving threats and attacks; this helped in ensuring firewall security and addressing network issues beforehand. This means that he performed managing and maintaining phase for this purpose. Deploying is the phase of firewall implementation and deployment that involves installing and activating firewalls in the network or system according to the plan. Testing is the phase of firewall implementation and deployment that involves verifying and validating the functionality and security of firewalls before putting them into operation. Configuring is the phase of firewall implementation and deployment that involves setting up and customizing firewalls according to the requirements and specifications.
