An objective of public key infrastructure (PKI) is to independently authenticate the validity of the sender’s public key. PKI is a system that uses cryptographic keys to secure communications and transactions. PKI involves a trusted third party called a certificate authority (CA) that issues digital certificates that link a public key with an identity. The recipient can use the CA’s public key to verify the sender’s certificate and public key.

 In key protection/management, access should be aligned with the principle of least privilege. This means that users should only have the minimum level of access required to perform their tasks and no more. This reduces the risk of unauthorized access, misuse, or compromise of sensitive data or systems.

Operating system rules can be configured to enforce password complexity requirements. These rules can specify the minimum length, complexity, and expiration of passwords. By setting these parameters, the operating system ensures that users create passwords that are difficult to guess or crack, thus enhancing security.

Multi-factor authentication (B) adds an additional layer of security but does not directly ensure the creation of complex passwords. Information security awareness © is crucial for educating users about the importance of complex passwords but does not enforce their creation. Biometrics (D) is an alternative form of authentication that may replace or supplement passwords but does not govern their complexity.

The incident management team is typically activated during the Identification phase of the incident response process. This phase involves detecting and determining the nature of the incident, which is crucial before any containment, eradication, or recovery efforts can begin. The team’s activation at this early stage ensures that the incident is properly identified and assessed, allowing for a more effective response.

References = The ISACA resources outline the incident response process and emphasize the importance of the Identification phase as the starting point for the incident management team’s activities. This is supported by the incident response models and guidance provided by ISACA, which detail the steps and phases involved in responding to security incidents12.

In the context of network communications, the two types of attack vectors are ingress and egress. Ingress refers to the unauthorized entry or access to a network, which can include various forms of cyberattacks aimed at penetrating network defenses. Egress,on the other hand, involves the unauthorized transmission of data out of a network, often as part of data exfiltration efforts by attackers1.

References: The ISACA Cybersecurity Fundamentals Glossary defines attack vectors in network communications as ingress and egress, which align with the options provided in the question1.
