Detailed Explanation: Security regression testing is a type of testing that verifies that the security features and functionality of an application are not compromised or broken by any changes or updates in the code2. Security regression testing can help to ensure that the application follows industry best practices for secure coding and does not introduce any new vulnerabilities or weaknesses. Security regression testing can be performed manually or automatically using tools or scripts that check for common security flaws and compliance with security standards. Security regression testing can also help to validate the error-handling capabilities of an application by testing how it responds to different types of inputs and scenarios. Input validation (A) is a technique that checks whether the inputs to an application are valid and expected before processing them3. Input validation can help to prevent some types of security attacks, such as injection attacks or buffer overflows, but it is not a way to verify that an application follows industry best practices for secure coding. Input validation is part of secure coding, not a way to test it. Application fuzzing © is a technique that tests an application by sending random or malformed inputs to it and observing its behavior4. Application fuzzing can help to discover some types of security vulnerabilities, such as memory leaks or crashes, but it is not a comprehensive way to verify that an application follows industry best practices for secure coding. Application fuzzing may not cover all possible inputs and scenarios and may not check for compliance with security standards. User acceptance testing (D) is a technique that tests an application by involving end users or customers in evaluating its functionality and usability. User acceptance testing can help to ensure that an application meets the user requirements and expectations, but it is not a reliable way to verify that an application follows industry best practices for secure coding. User acceptance testing may not focus on security aspects and may not detect subtle or hidden security flaws. Stress testing (E) is a technique that tests an application by subjecting it to high levels of load or demand. Stress testing can help to evaluate the performance and reliability of an application under extreme conditions, but it is not a relevant way to verify that an application follows industry best practices for secure coding. Stress testing does not check for security issues and may not reflect normal usage patterns.

IaC stands for infrastructure as code, which is a practice of using code or configuration files to automate the provisioning and management of cloud resources. IaC templates can help ensure consistency, repeatability, and scalability of cloud deployments, as well as reduce human errors and misconfigurations. However, IaC templates need to be validated and tested before deployment, and any changes to the templates should be controlled and monitored. This can help minimize the occurrence of vulnerabilities introduced by unintentional misconfigurations in the cloud

To prevent adversaries from intercepting response and recovery details. Using a secure method of communication during incident response is important to prevent adversaries from intercepting response and recovery details that could reveal the incident response team’s actions, strategies, or findings. If the adversaries can intercept the communication, they could use it to evade detection, escalate their privileges, or launch further attacks. To ensure intellectual property remains on company servers, to have a backup plan in case email access is disabled, or to ensure the management team has access to all the details that are being exchanged are other possible reasons to use a secure method of communication, but they are not as important as preventing adversaries from intercepting response and recovery details.

The Diamond Model of Intrusion Analysis is a framework for analyzing and understanding malicious activity on a system or network. It defines the basic atomic element of any intrusion activity as the event, which consists of four core features: adversary, infrastructure, capability, and victim. These features are connected by edges that represent their underlying relationships and arranged in the shape of a diamond1 The infrastructure feature refers to the physical or logical communication structures that are used by the adversary to deliver a capability or interact with a victim. Examples of infrastructure elements are IP addresses, domain names, email addresses, servers, routers, etc. The domain, IP address, email address, and software version that the analyst extracted from the artifacts are all examples of infrastructure elements that can be used to identify or track the adversary’s activity.

A cloud access security broker (CASB) is a security solution that monitors and controls the use of cloud-based services and applications. A CASB can provide data loss prevention (DLP) capabilities for sensitive data that is being stored in the cloud, such as encryption, masking, tokenization, or redaction. A CASB can also enforce policies and compliance requirements for cloud usage, such as authentication, authorization, auditing, and reporting. The other options are not appropriate solutions for controlling sensitive data in the cloud.

The packet capture shows that the host sent a Client Hello message to utoftor.com on port 443. This message is part of the TLS (Transport Layer Security) handshake protocol, which is used to establish a secure connection between a client and a server1. The Client Hello message contains information such as the supported TLS version, cipher suites, and extensions that the client can use for the secure connection. The server is expected to respond with a Server Hello message that selects the parameters for the secure connection. However, the packet capture does not show any response from the server, which means that the host only attempted to make a secure connection to utoftor.com, but did not succeed. The host did not download (B) or reject (D) any application from utoftor.com.

Pll stands for Personally Identifiable Information, and it is any data that can be used to identify, locate, or contact an individual. Examples of Pll include names, addresses, phone numbers, email addresses, social security numbers, bank account numbers, etc. The first step to secure the organization’s Pll is to identify what type of Pll is on the network, where it is stored, who has access to it, and how it is transmitted. This can help determine the scope and impact of the deficiency in the policies and procedures for Pll.

Implementing a secure supply chain program with governance would be the best way to ensure the third-party service provider meets the requirement of only sourcing talent from its own country. A secure supply chain program is a set of policies, procedures, and controls that aim to protect the integrity and security of the products and services delivered by third-party vendors. A secure supply chain program can help mitigate the risks of geopolitical and national security interests by verifying the origin, identity, and trustworthiness of the vendors and their employees1. Governance is a key component of a secure supply chain program, as it provides oversight, accountability, and enforcement of the policies and procedures.
