The network administrator wants to strengthen physical security in the organization. Specifically, to implement a solution stopping people from entering certain restricted zones without proper credentials. Which of
following physical security measures should the administrator use?
A mantrap is a physical security mechanism designed to control access to a secure area through a small space with two sets of interlocking doors. It is an effective measure to prevent unauthorized access, as it allows only one person to pass through at a time after authentication, thereby stopping any attempt at 'tailgating' or 'piggybacking' where an unauthorized individual might try to follow an authorized person into a restricted zone.
Identify the spread spectrum technique that multiplies the original data signal with a pseudo random noise spreading code.
The spread spectrum technique that involves multiplying the original data signal with a pseudo-random noise spreading code is known as Direct Sequence Spread Spectrum (DSSS). In DSSS, the data signal is combined with a higher data-rate bit sequence, also known as a chipping code, which divides the data according to a spreading ratio. The chipping code is a pseudo-random code sequence that spreads the signal across a wider bandwidth. This process allows the signal to be more resistant to interference and eavesdropping.
Ryan works as a network security engineer at an organization the recently suffered an attack. As a countermeasure, Ryan would like to obtain more information about the attacker and chooses to deploy a honeypot into the organizations production environment called Kojoney. Using this honeypot, he would like to emulate the network vulnerability that was attacked previously. Which type of honeypot is he trying to implement?
A low-interaction honeypot, like Kojoney, is designed to emulate specific network vulnerabilities and gather information about attackers without providing a full-fledged operating environment. These honeypots are typically easier to deploy and maintain compared to high-interaction honeypots. They simulate certain services and responses to attract attackers, allowing the network security team to gather data on attack patterns, tools, and methodologies used by the attackers. This information is crucial for understanding the attack and improving defenses.
High-interaction honeypots: Provide a complete environment that can fully engage with attackers, offering more detailed insights but also posing higher risks.
Pure honeypots: Essentially full-scale, unmodified systems that an attacker interacts with.
Research honeypots: Used primarily for gathering information for research purposes, often involving high-interaction setups.

Peter works as a network administrator at an IT company. He wants to avoid exploitation of the cloud, particularly Azure services. Which of the following is a group of PowerShell scripts designed to help the network administrator understand how attacks happen and help them protect the cloud?
MicroBurst is a collection of PowerShell scripts designed to help network administrators understand how attacks occur and to protect cloud environments, particularly Azure services. These scripts aid in detecting vulnerabilities, simulating attacks, and implementing defensive measures to secure the cloud infrastructure.
POSH-Sysmon: A set of PowerShell scripts for managing Sysmon configurations.
SecurityPolicyDsc: A module for managing security policies through Desired State Configuration (DSC).
Sysmon: A Windows system service and device driver that logs system activity to the Windows event log, not specifically focused on cloud protection.

Which of the following systems includes an independent NAS Head and multiple storage arrays?
A Gateway NAS System is characterized by having an independent NAS head that manages file services and multiple storage arrays. This configuration allows for the NAS head to be connected to external storage arrays, providing flexibility and scalability. The NAS head serves as the gateway between the clients and the storage arrays, managing file I/O requests and directing them to the appropriate storage resources.
