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:

Joseph, a security professional, was instructed to secure the organization's network. In this process, he began analyzing packet headers to check whether any indications of source and destination IP addresses and port numbers are being changed during transmission.
Identify the attack signature analysis technique performed by Joseph in the above scenario.
Atomic-signature-based analysis is a type of attack signature analysis technique that uses a single characteristic or attribute of a packet header to identify malicious traffic. Atomic signatures are simple and fast to match, but they can also generate false positives or miss some attacks. Some examples of atomic signatures are source and destination IP addresses, port numbers, protocol types, and TCP flags. Atomic-signature-based analysis is the technique performed by Joseph in the above scenario, as he analyzed packet headers to check whether any indications of source and destination IP addresses and port numbers are being changed during transmission.

Barbara, a security professional, was monitoring the loT traffic through a security solution. She identified that one of the infected devices is trying to connect with other loT devices and spread malware onto the network. Identify the port number used by the malware to spread the infection to other loT devices.
Port 48101 is the port number used by the malware to spread the infection to other loT devices. This port is associated with the Mirai botnet, which is one of the most notorious loT malware that targets vulnerable loT devices and turns them into a network of bots that can launch distributed denial-of-service (DDoS) attacks. Mirai scans the internet for loT devices that use default or weak credentials and infects them by logging in via Telnet or SSH. Once infected, the device connects to a command and control (C&C) server on port 48101 and waits for instructions. The C&C server can then direct the botnet to attack a target by sending TCP, UDP, or HTTP requests. Mirai has been responsible for some of the largest DDoS attacks in history, such as the one that disrupted Dyn DNS in 2016 and affected major websites like Twitter, Netflix, and Reddit. Reference:
