ECCouncil Updated 712-50 Exam Questions and Answers by saoirse

 Explanation:

Granting broad access to critical functions like accounting period setups is often a result of inadequate segregation of duties.

Proper policies would limit access to essential personnel, reducing the risk of errors or fraud.

 Why Other Options Are Incorrect:

A. Changing periods regularly: Does not justify access beyond finance personnel.

B. Posting entries for a closed period: Limited personnel should handle this, not multiple departments.

C. Chart of accounts modifications: A specialized task, not broadly needed across departments.

 EC-Council CISO Reference:

Reinforces the need for strict access controls and clear segregation of duties as a security best practice.

 Encrypting Confidential Emails:

Public-key cryptography ensures confidentiality by allowing the sender to encrypt a message using the recipient’s public key. Only the recipient can decrypt it using their private key.

 Key Functionality:

Recipient's Public Key: Encrypts data securely.

Recipient's Private Key: Used exclusively to decrypt the message.

 Why Not Other Options:

A. Your public key: Encrypts messages meant for you, not for others.

B. The recipient's private key: Private keys should never be shared or used for encryption.

D. Certificate authority key: Used for signing certificates, not encrypting messages.

 EC-Council Emphasis:

The correct use of cryptographic keys ensures confidentiality and aligns with secure communication protocols.

Tuning an Intrusion Detection System (IDS) is a critical task that ensures optimal detection of malicious activities while minimizing false positives and false negatives. The most important factor during this process is distinguishing between trusted and untrusted networks because IDS relies heavily on understanding traffic sources and destinations to differentiate legitimate traffic from potential threats.

Identification of Network Zones:

Trusted networks usually include internal enterprise systems with known, monitored activity.

Untrusted networks refer to external sources such as the internet or third-party services that may harbor threats.

Baseline Definition:

By clearly defining what constitutes normal behavior for trusted and untrusted zones, an IDS can be configured to flag anomalies effectively.

Ruleset Customization:

Trusted zones require minimal scrutiny for legitimate internal communications, while untrusted zones often need stricter monitoring.

Reduction of False Positives:

Misclassification between trusted and untrusted zones can lead to excessive alerts or overlooked threats. Proper tuning reduces these errors.

Threat Intelligence Integration:

Ensuring proper network classifications allows seamless integration of threat intelligence feeds, providing accurate detection in untrusted zones while maintaining efficiency in trusted zones.

Detection and Response: EC-Council emphasizes that understanding network boundaries and applying them to security mechanisms, such as IDS, is crucial for effective threat detection.

Network Security Architecture: In EC-Council’s methodologies, classification of trusted/untrusted networks forms the foundation for creating robust security policies.

Strategic Risk Management: Identifying zones also aids in aligning IDS tuning with broader organizational risk management strategies.

EC-Council CISO References:By focusing on trusted and untrusted network delineation during IDS tuning, organizations ensure that their detection systems are both effective and efficient. This process aligns with EC-Council’s principles of maintaining a balance between proactive detection and operational manageability.

 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.
