Authentication Defined:

Authentication is the process of verifying the identity of an entity (person, system, or device) seeking access to resources.

Typically involves something the user knows (password), has (token), or is (biometric).

Comparison with Related Terms:

Identification: Specifies who the user claims to be (e.g., username).

Authorization: Determines what resources the authenticated user can access.

Accountability: Tracks user actions after authentication and authorization.

To effectively identify technical vulnerabilities, system scans are among the most effective methods. These scans can automatically detect security weaknesses in software, configurations, and systems. Tools like vulnerability scanners perform automated checks against databases of known vulnerabilities, ensuring comprehensive coverage across IT environments. While reviewing logs, auditing templates, and checking vendor releases contribute to overall security, scanning is both systematic and thorough in identifying vulnerabilities.

 Reducing the Burden of Key Distribution

Asymmetric encryption provides a secure mechanism for distributing symmetric keys without requiring physical transfer.

Public keys are used to encrypt the symmetric key, which can then be decrypted by the corresponding private key.

 Why Not Other Options?

B. Use a self-generated key: Does not address distribution challenges.

C. Use a certificate authority: Distributes certificates, not symmetric keys.

D. Symmetrically encrypt and then decrypt: Adds unnecessary complexity without addressing distribution.

 EC-Council References

Recommends hybrid encryption models that combine the strengths of symmetric and asymmetric encryption to streamline secure key distribution.
