Vulnerability scanning is a proactive security measure used to identify vulnerabilities in the network and systems. Reference: CompTIA Security+ Study Guide 601, Chapter 4

To determine the total risk an organization can bear, a technician should review the organization's risk tolerance, which is the amount of risk the organization is willing to accept. This information will help determine the organization's "cloud-first" adoption strategy. Reference: CompTIA Security+ Certification Exam Objectives (SY0-601)

After segmenting the network, a network manager can use an access control list (ACL) to control the traffic between the segments. An ACL is a set of rules that permit or deny traffic based on its characteristics, such as the source and destination IP addresses, protocol type, and port number. Reference: CompTIA Security+ Certification Guide, Exam SY0-501

Detailed Continuous Integration (CI) is a practice where developers integrate code into a shared repository frequently, preferably several times a day. Each integration is verified by an automated build and automated tests. CI allows for the detection of errors early in the development cycle, thereby reducing overall development costs.
