Immutable data storage protects against ransomware threats by ensuring that once data is written, it cannot be altered or deleted. This technology prevents ransomware from encrypting or modifying critical backups, enabling rapid restoration. Options B, C, and D are valuable for prevention and awareness but do not provide the direct protection against ransomware that immutable storage offers.

Common Data Hiding Techniques:

Encryption: Conceals data by transforming it into an unreadable format without the decryption key.

Steganography: Hides data within other files, such as images or videos, making detection difficult.

Metadata/Timestamp Manipulation: Alters file metadata or timestamps to obscure activity trails.

Why Not Other Options:

A, B, and C: While these may be related to other criminal activities, they do not represent core data hiding techniques.

The Recovery Point Objective (RPO) represents the maximum acceptable amount of data loss measured in time before a disaster or disruption. RPO is critical for data backup and restoration in the Business Impact Assessment (BIA), as it determines the frequency of backups needed to meet continuity requirements. RTO (C) relates to the time required to recover systems, while MTD (D) defines the maximum downtime before critical impact.

Role of Internal Audit in Audit Directive Implementation:

The internal audit team ensures that all audit directives and recommendations are implemented effectively within the organization.

They verify compliance, assess controls, and report findings to the Board of Directors or Audit Committee.

Why Not Other Options:

A: IT management implements the directives but does not verify them.

C: IT security focuses on technical security implementations, not directive verification.

D: The Audit Committee oversees audits but does not directly verify implementation.

Sanitizing datasets ensures that sensitive information is removed or anonymized before AI products are developed or deployed. This mitigates risks associated with data breaches or unauthorized use of data, especially in sensitive industries like banking. While hashing, encrypting, or deleting datasets provides security, sanitization is critical to protect privacy and comply with regulations like GDPR or CCPA, particularly when handling AI datasets.

Successful cyber-attacks often involve a combination of phishing attacks, misconfigurations, and social engineering. These tactics exploit human and technical vulnerabilities, with phishing being a common initial attack vector, misconfigurations exposing systems to exploitation, and social engineering manipulating individuals to reveal sensitive information. Together, these methods account for a large proportion of successful breaches.

The process of identifying and classifying assets is integral to Business Impact Analysis (BIA) because it determines which assets are critical to the organization and how their loss would impact business operations. This classification informs risk assessments, disaster recovery plans, and security prioritizations.

Identification of Assets:

Assets include hardware, software, data, and personnel. These are cataloged as part of the BIA to understand their role in business processes.

Classification:

Assets are classified based on criticality and sensitivity, considering how their compromise would affect confidentiality, integrity, or availability.

Mapping Dependencies:

BIA also involves mapping dependencies between assets and business processes to identify cascading impacts.

Determining Impact:

The financial, operational, legal, and reputational impact of asset loss or compromise is assessed.

Foundation for Risk Mitigation:

Asset classification through BIA forms the basis for prioritizing protective measures in disaster recovery and risk management.

Risk and Business Impact: EC-Council emphasizes BIA as a cornerstone in identifying and safeguarding critical business functions and assets.

Asset Management Framework: Proper classification under BIA supports alignment with cybersecurity frameworks like ISO 27001.

EC-Council CISO References:

 Explanation:

Non-repudiation ensures that a party cannot deny the authenticity of their digital signature or transaction.

Digital signatures provide this assurance by cryptographically linking the signer to the transaction, safeguarding transaction integrity and authenticity.

 Why Other Options Are Incorrect:

B. Conflict resolution: Refers to resolving disputes but does not describe the capability of proving a transaction.

C. Strong authentication: Relates to verifying identity but not to preventing denial of actions.

D. Digital rights management: Concerns content protection, not transaction integrity.

 EC-Council CISO Reference:Emphasizes the role of non-repudiation in maintaining trust and integrity in digital transactions.

 Preventing Unauthorized Database Access:Input sanitization ensures that web applications validate and cleanse user inputs to prevent malicious payloads, such as SQL injection, from being executed.

 Why Input Sanitization Works:

Blocks injection attacks by filtering out harmful characters and queries.

Enforces strict input formats, reducing risks from malicious user input.

 Why Not Other Options:

A. Session encryption: Protects data in transit, not database access.

B. Removing stored procedures: Disrupts functionality without addressing input risks.

D. Library control: Reduces vulnerabilities in dependencies but does not address input directly.

 EC-Council Guidance:Input validation is a cornerstone of secure coding practices for safeguarding databases from unauthorized access.

 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.
