ECCouncil Updated 712-50 Exam Questions and Answers by leona

 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.

3DES (Triple Data Encryption Standard) is a symmetric encryption algorithm. It uses the same key for both encryption and decryption, distinguishing it from asymmetric algorithms.

Symmetric Encryption Overview:

Symmetric encryption uses a single key shared between the sender and receiver for encrypting and decrypting data.

3DES Mechanism:

3DES encrypts data three times using the DES algorithm with three different keys, enhancing security over the original DES.

Comparison with Other Options:

MD5: Not an encryption algorithm; it’s a cryptographic hash function.

ECC (Elliptic Curve Cryptography) and RSA: Both are asymmetric algorithms, using separate public and private keys.

Applications:

Widely used in financial services, although increasingly replaced by more secure algorithms like AES.

Encryption Fundamentals: EC-Council identifies 3DES as a legacy symmetric encryption method, suitable for understanding encryption evolution.

Security Practices: Guidance on transitioning from 3DES to modern algorithms aligns with EC-Council’s focus on advanced security.

 Definition of Social Engineering

Social engineering is a non-technical attack method that manipulates human behavior to gain unauthorized access to information, systems, or physical locations. It typically exploits trust, ignorance, or carelessness.

 Characteristics

Least Equipment Needed: Social engineering often requires no more than communication tools (e.g., phone, email) or physical presence.

Highest Success Rate: Human error is a common vulnerability, making this approach highly effective, especially when attackers exploit psychological triggers like urgency, fear, or curiosity.

 Comparison of Options

A. War driving: Requires equipment for detecting wireless networks and relies on the presence of weak Wi-Fi configurations.

B. Operating system attacks: Involves identifying and exploiting OS vulnerabilities, requiring technical expertise and tools.

D. Shrink wrap attack: Exploits default or unpatched software installations, requiring more specific conditions than social engineering.

 EC-Council References

CISO Insights: Social engineering attacks like phishing, pretexting, and baiting are consistently highlighted as major threats in EC-Council's curriculum.

Incident Reports: Case studies in EC-Council's guidance show social engineering's prevalence and effectiveness across various sectors.

 Conclusion

Social engineering, due to its simplicity and effectiveness in exploiting human behavior, is the attack type requiring the least technical equipment and yielding the highest success rate.

 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.
