Kelly, a cloud administrator at TechSol Inc., was instructed to select a cloud deployment model to secure the corporate data and retain full control over the data.
Which of the following cloud deployment models helps Kelly in the above scenario?
A private cloud is a cloud deployment model that is exclusively used by a single organization and is hosted either on-premises or off-premises by a third-party provider. A private cloud offers the highest level of security and control over the data and resources, as the organization can customize the cloud infrastructure and services according to its needs and policies. A private cloud also ensures better performance and availability, as the organization does not share the cloud resources with other users. A private cloud is suitable for organizations that have sensitive or confidential data, strict compliance requirements, or high demand for scalability and flexibility. A private cloud can help Kelly secure the corporate data and retain full control over the data in the above scenario. Reference:

Messy, a network defender, was hired to secure an organization's internal network. He deployed an IDS in which the detection process depends on observing and comparing the observed events with the normal behavior and then detecting any deviation from it.
Identify the type of IDS employed by Messy in the above scenario.
Anomaly-based IDS is a type of IDS that detects intrusions by comparing the observed network events with a baseline of normal behavior and identifying any deviation from it. Anomaly-based IDS can detect unknown or zero-day attacks that do not match any known signature, but they can also generate false positives due to legitimate changes in network behavior. Anomaly-based IDS can use various techniques to model the normal behavior, such as statistical analysis, machine learning, or artificial intelligence. Anomaly-based IDS is the type of IDS employed by Messy in the above scenario, as he deployed an IDS that depends on observing and comparing the observed events with the normal behavior and then detecting any deviation from it.

Which of the following tools is designed to identify and prevent malicious Trojans or malware from infecting computer systems or electronic devices?
Which of the following types of network segmentation is an easy approach to divide a network but can be expensive as it occupies more space?
Identify the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it suspectable to theft or natural disasters.
Onsite data backup is the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it susceptible to theft or natural disasters. Onsite data backup means storing the backup data on a local storage device, such as an external hard drive, a USB flash drive, a CD/DVD, or a tape drive, that is physically located in the same premises as the original data source. Onsite data backup has some advantages, such as fast backup and restore speed, easy access, and low cost. However, it also has some disadvantages, such as requiring manual intervention, occupying physical space, and being vulnerable to damage, loss, or theft. If a disaster, such as a fire, flood, earthquake, or power outage, occurs in the organization, both the original data and the backup data may be destroyed or inaccessible. Therefore, onsite data backup is not a reliable or secure way to protect the data from unforeseen events. Reference:
