 Explanation:

Deep-packet inspection (DPI) involves analyzing the content of packets in real-time as they traverse a network.

DPI can examine both headers and payloads of packets without introducing noticeable latency, making it suitable for real-time traffic monitoring.

 Why Other Options Are Incorrect:

A. Traffic analysis: Focuses on metadata such as packet sizes, timing, and flow but does not inspect content.

C. Packet sampling: Involves analyzing only a subset of packets, potentially missing key information.

D. Heuristic analysis: Used for identifying patterns but does not specifically describe real-time deep inspection of packets.

 EC-Council CISO Reference:

DPI is a critical technology discussed in advanced network security for monitoring and identifying malicious activity without impacting performance.

Explanation:

An Enterprise Risk Assessment evaluates potential threats and their impact on the organization.

This helps determine the appropriate investment in building a secondary data center to mitigate identified risks.

Why Other Options Are Incorrect:

B. Disaster recovery strategic plan: Focuses on recovery steps, not the spending allocation for infrastructure.

C. Business continuity plan: Addresses operational recovery but does not provide a financial framework.

D. Application mapping document: Provides application dependencies but not cost analysis for infrastructure.

EC-Council CISO Reference:The program stresses the role of risk assessments in aligning investments with the organization’s risk tolerance and needs.

 Investigative Support for Open Guest Networks:

IP and MAC addresses associated with network activity provide crucial identifiers for tracing a user's activity. This is especially helpful for law enforcement when investigating illegal activities.

 Why IP and MAC Address Are Critical:

IP Address: Helps identify network traffic origin during a specific time frame.

MAC Address: Provides device-specific identification.

 Why Not Other Options:

A. Configure logging on each access point: While useful, it does not directly assist without extracting IP and MAC addresses.

B. Install firewall software: Does not help track user activity retroactively.

D. Disable SSID broadcast and enable MAC filtering: Prevents unauthorized access but doesn’t support investigations.

 EC-Council CISO Alignment:

Proper logging and identification practices ensure legal compliance and effective support during investigations.

 Explanation:

Physical security measures typically include:

Physical: Locks, barriers, and surveillance systems.

Technical: Access control systems and alarm systems.

Operational: Security policies, procedures, and personnel training.

 Why Other Options Are Incorrect:

B. Technical, Strong Password, Operational: Passwords are part of logical security, not physical security.

C. Operational, Biometric, Physical: Biometrics is part of technical security measures, not operational.

D. Strong Password, Biometric, Common Access Card: Passwords are not physical security measures.

 EC-Council CISO Reference:

The curriculum outlines the layered approach to security, with physical, technical, and operational components as critical for comprehensive protection.

 Temporal Keys in WPA2:

WPA2 uses the Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES) to dynamically generate unique keys for each session.

Temporal keys enhance security by preventing key reuse.

 Key Features of WPA2:

Strong encryption and authentication mechanisms.

Improved resilience against attacks compared to WEP.

 Why Not Other Options:

A. WAP: Refers to Wireless Application Protocol, unrelated to encryption.

C. WEP: Uses static keys, not temporal keys.

D. EAP: An authentication framework, not a wireless encryption protocol.

 EC-Council CISO Alignment:

WPA2’s use of temporal keys demonstrates its suitability for secure wireless communication, as emphasized in encryption best practices.

The Simple Network Management Protocol (SNMP) uses "community strings" as a form of authentication. The default read-only string for SNMP is often set to "Public".

SNMP Overview:

SNMP is used for monitoring and managing network devices such as routers, switches, and servers.

Default Community Strings:

Default strings like "Public" (read-only) and "Private" (read-write) are well-known and often targeted by attackers if not changed.

Penetration Test Findings:

Discovering devices through SNMP indicates improper security practices where default settings haven’t been updated, making devices vulnerable.

Mitigation:

Change SNMP community strings to strong, unique values.

Restrict SNMP access to trusted IP ranges.

Configuration Management: Emphasizes updating default settings as a baseline security measure.

Penetration Testing Insights: Findings like this are critical for improving network security posture, aligning with EC-Council’s penetration testing methodologies.

EC-Council CISO References:

 WEP and Shared Key Authentication:

WEP (Wired Equivalent Privacy) uses shared keys for authentication and encryption, meaning all devices and the access point use the same key for communication.

 Key Characteristics:

Relies on pre-shared keys.

Vulnerable to cryptographic attacks due to weak key management and reuse.

 Why Not Other Options:

B. Asynchronous: Not relevant in the context of WEP.

C. Open: Refers to an authentication method with no encryption, not involving shared keys.

D. None: Incorrect; WEP uses shared keys for authentication.

 EC-Council Guidance:

Understanding WEP’s limitations and vulnerabilities is crucial for mitigating risks in wireless network environments.

Corporate governance establishes a framework of rules and practices to ensure accountability, fairness, and transparency in an organization's dealings with shareholders and other stakeholders. This includes oversight of the organization’s strategic direction, risk management, and performance. Internal audit (A) and risk oversight (C) are components of governance, while key performance indicators (D) are metrics used for tracking objectives.

 Definition of Annual Loss Expectancy (ALE)

ALE is a quantitative risk analysis metric used to estimate the annual financial impact of a risk.

Formula: ALE = Annual Rate of Occurrence (ARO) × Single Loss Expectancy (SLE)

 Key Components

Annual Rate of Occurrence (ARO): The estimated frequency of a specific risk occurring in a year.

Single Loss Expectancy (SLE): The financial impact of a single occurrence of the risk, calculated as Asset Value × Exposure Factor.

 Comparison of Options

A. Annual Rate of Occurrence and Asset Value: Asset Value is used indirectly in SLE but not directly with ARO.

B. Single Loss Expectancy and Exposure Factor: These factors combine to calculate SLE, not ALE.

C. Safeguard Value and Annual Rate of Occurrence: Safeguard Value is unrelated to ALE calculation.

 EC-Council References

EC-Council frameworks and CISO resources consistently highlight ALE as a critical tool for financial risk assessment.

If the scalability issue impacts only a small number of network segments, the next logical step is to determine if sufficient mitigating controls can address the issue without replacing the entire solution.

Risk Assessment:

Identifies the extent of the issue and potential mitigation strategies.

Considers controls to reduce the impact on affected segments.

Risk Mitigation:

If feasible controls exist, they can minimize risk while retaining the original solution.

Other Options:

A: Use cases are secondary to resolving the core issue.

C: Risk acceptance should only occur after exploring mitigation options.

D: Reporting deficiencies to audit is procedural but does not address the risk.

Risk Mitigation Strategies: Prioritizes applying controls to reduce risks to acceptable levels.

Incident and Problem Management: Emphasizes minimizing operational impact through mitigation.
