===========

ISO/IEC 27005 is explicitly identified in EC-Council CCISO documentation as the standard providing a formal framework for information security risk management.

ISO 27005 supports ISO 27001 by defining risk identification, analysis, evaluation, treatment, and monitoring. COBIT focuses on IT governance, ISO 27003 on ISMS implementation, and ITIL on service management.

Thus, Option A is correct.

 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.

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.
