Which of the following is NOT a layer of security used by Avaya?

In the context of Avaya’s security measures, the primary layers of security consist of encryption, authentication, and access control, all of which are critical in safeguarding communication systems.

Encryption protects data by converting it into a secure format that can only be read or processed by someone with the proper decryption key. This helps ensure the integrity and confidentiality of communications over networks.

Authentication verifies the identities of users and systems, confirming that they are who they claim to be, thereby preventing unauthorized access. This is essential in maintaining the security of sensitive data and ensuring that only approved individuals can access specific resources.

Access control is the set of rules and policies that determine who has permission to access certain resources within the Avaya system. This layer helps to limit access based on user roles, thus maintaining security by ensuring that users only have access to the information and functionalities that are appropriate for them.

In contrast, manual logs, while useful for tracking activity or auditing purposes, do not constitute a security layer in the same way that the other options do. They are more of a log-keeping measure rather than an active security mechanism. Hence, identifying manual logs as not a layer of security accurately reflects the principle that effective security measures must proactively protect data and manage access
