The incident response cycle's preparation phase includes establishing policies and procedures for reporting lost or stolen devices promptly. If an employee's device was missing for 96 hours before being reported, this indicates a lack of awareness or clear procedures on the employee's part, pointing to inadequacies in the preparation phase of the incident response.

Risk acceptance is the decision to accept the potential risk and continue operating without engaging in extraordinary measures to mitigate it. If the cost of anti-malware exceeds the potential loss from a malware threat, it would be more cost-effective to accept the risk rather than spend more on mitigations that don't provide proportional value. This is part of a cost-benefit analysis in risk management.

OAuth, which stands for Open Authorization, is a standard for authorization that enables secure token-based access. It allows users to grant a web application access to their information on another web application without giving them the credentials for their account. OAuth is particularly useful for rapid authentication, flexible authorization, ease of deployment, and offers high functionality at a low cost, making it an ideal choice for new web-based applications. This approach is well-suited for situations where web applications need to interact with each other on behalf of the user, without sharing user's password, such as integrating a geolocation application with Facebook. OAuth uses tokens issued by an authorization server, providing restricted access to a user's data, which aligns with the objectives of rapid authentication, flexible authorization, ease of deployment, and cost-effectiveness.

To securely operate the camera, the security analyst should recommend hardening the camera configuration. This involves several steps:

Changing Default Credentials: Default usernames and passwords are a common vulnerability. They should be replaced with strong, unique passwords.

Disabling Unnecessary Services and Ports: The numerous open ports and insecure protocols should be reviewed, and any unnecessary services should be disabled to reduce the attack surface.

Firmware Updates: Ensuring the camera's firmware is up to date will mitigate known vulnerabilities.

Enable Encryption: If possible, enable encryption for both data in transit and at rest to protect the video stream and other communications from interception.

This approach addresses the identified vulnerabilities directly and ensures that the device is more secure. Simply sending logs to the SIEM or isolating the camera might not fully mitigate the risks associated with default settings and open ports.

An inspection proxy, also known as an SSL/TLS inspection proxy, can decrypt HTTPS traffic, allowing the IDS to analyze the content for malicious activity. This method ensures that encrypted traffic can be inspected without compromising the security of the data in transit. The inspection proxy will re-encrypt the data before sending it on to its destination, maintaining the confidentiality of the communication while enabling security tools to perform their functions.

The Chief Information Security Officer (CISO) should highlight social engineering as an area of increased vulnerability due to the lack of completion of security awareness training by employees. Social engineering attacks exploit human behavior, and employees who are not adequately trained are more likely to fall victim to phishing, pretexting, and other types of social engineering tactics. Increasing awareness and training helps employees recognize and respond appropriately to these threats.

Certificate Authority Authorization (CAA) is not listed directly in the provided options, but it is a relevant mechanism in the context of managing certificates and preventing issues similar to the one described. However, based on the available choices, the Online Certificate Status Protocol (OCSP) comes closest to providing a viable solution. OCSP allows for real-time validation of a certificate's revocation status, which could mitigate the issue of users being locked out due to key pinning policies. It is a more modern and efficient alternative to Certificate Revocation Lists (CRLs), offering faster and more reliable certificate status checks. By implementing OCSP, the technician could ensure that clients receive timely updates on the revocation status of certificates, potentially avoiding the downtime caused by the key-pinning policy awaiting expiration.

An API gateway is a management tool that sits between a client and a collection of backend services. It acts as a reverse proxy to accept all application programming interface (API) calls, aggregate the various services required to fulfill them, and return the appropriate result. API gateways can enforce policies such as rate limiting and authentication to prevent unauthorized access, making it an effective solution to prevent unauthorized API key sharing. By managing APIs at the gateway level, organizations can ensure that API keys are used as intended and are not shared or misused, addressing the need for secure management of API keys.

A Service Level Agreement (SLA) is the document used to specify due dates for the remediation of high- and critical-priority findings. SLAs outline the responsibilities of the service provider, including time frames for addressing issues or vulnerabilities, based on their severity. By setting clear timelines for remediation, SLAs ensure that critical security vulnerabilities are addressed in a timely manner. CASP+ emphasizes the importance of SLAs in maintaining accountability for security operations and ensuring compliance with organizational security policies.
