712-50 Exam Dumps - ECCouncil CCISO Questions and Answers

 Encapsulating Security Payload (ESP):ESP is a protocol within the IPSec suite that provides confidentiality, integrity, and authentication for network traffic by encrypting packet payloads.

 Key Features of ESP:

Operates at the network layer.

Ensures data confidentiality and protects against tampering.

 Why Not Other Options:

B. Text-based communication protocol: ESP is not text-based; it deals with encrypted data.

C. Uses TCP port 22: ESP does not operate at the application layer.

D. Uses UDP port 22: Incorrect; ESP typically uses protocol number 50.

 EC-Council Emphasis:ESP’s role in securing IP communications highlights its importance in modern security architectures.

 Explanation:

Electronic discovery (e-discovery) involves identifying, collecting, and producing electronically stored information (ESI) as evidence in legal proceedings.

This includes emails, documents, and other digital files relevant to the case.

 Why Other Options Are Incorrect:

A. Chain of custody: Refers to the process of maintaining and documenting evidence handling.

C. Evidence tampering: Describes the illegal alteration of evidence, not the process of discovery.

D. Electronic review: Involves reviewing digital information but is part of the broader e-discovery process.

 EC-Council CISO Reference:Covers the importance of e-discovery in legal and compliance contexts, ensuring organizations are prepared to handle digital evidence properly.

 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.

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.

EC-Council CISO References:

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:

 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.

 Explanation:

Data classification is the process of categorizing data based on its sensitivity and security level to ensure appropriate access controls.

It helps organizations manage and protect private and sensitive data effectively.

 Why Other Options Are Incorrect:

A. Security coding: Refers to secure programming practices.

B. Data security system: A broad term that does not specifically describe categorization.

D. Privacy protection: Focuses on safeguarding individual privacy but does not involve categorization of data.

 EC-Council CISO Reference:Data classification is a fundamental practice in information security management, enabling organizations to align protection levels with data sensitivity.

 Explanation:

In-line hardware keyloggers are physical devices placed between a keyboard and a computer.

They are a concern because they are not detectable by software-based monitoring tools, posing a significant risk to the confidentiality of sensitive information.

 Why Other Options Are Incorrect:

A. Don’t require physical access: Physical access is required to install the hardware.

B. Don’t comply with regulations: While true, this is a secondary concern compared to their undetectability.

D. Are relatively inexpensive: Cost is a factor but not the primary security concern.

 EC-Council CISO Reference:The curriculum addresses the risks posed by hardware-based attacks and the need for physical security controls to mitigate such threats.

 Explanation:

Maintaining power ensures volatile memory (RAM) data is preserved, which can contain critical forensic evidence such as running processes and network connections.

Securing the area prevents tampering or unauthorized access, preserving the integrity of evidence.

 Why Other Options Are Incorrect:

A. Shut-down the computer: Shutting down can result in loss of volatile data critical to the investigation.

C. Place components in anti-static bags: Prematurely removing hardware disrupts the state of the machine and can lead to loss of evidence.

D. Secure the area: While important, it does not address the need to preserve volatile memory.

 EC-Council CISO Reference:The first-responder guidelines stress the importance of preserving evidence integrity and avoiding actions that could destroy critical forensic data.

 Explanation:

Incident response encompasses the processes and actions taken to assess, contain, and mitigate security breaches.

It includes detection, investigation, containment, and recovery activities.

 Why Other Options Are Incorrect:

A. IT support team: May assist but lacks the specialized role of incident response teams.

B. Forensic analysis: A part of the incident response process but does not encompass the entire containment effort.

D. Physical security team: Relevant for physical breaches, not digital security incidents.

 EC-Council CISO Reference:Incident response is a critical component of the CISO role, focusing on minimizing damage and ensuring swift recovery from breaches.
