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.
A popular e-commerce company has recently received a lot of complaints from its customers. Most
of the complaints are about the customers being redirected to some other website when trying to
access the e-com site, leading to all their systems being compromised and corrupted. Upon
investigation, the network admin of the firm discovered that some adversary had manipulated the
company's IP address in the domain name server's cache. What is such an attack called?
The attack described is known as DNS Poisoning, also referred to as DNS Spoofing. This type of attack occurs when an attacker manipulates the DNS server's cache, so that the server returns an incorrect IP address for a website. This results in users being redirected to malicious websites instead of the intended destination. The attacker's goal is typically to spread malware, steal personal information, or disrupt services. DNS Poisoning is a serious security threat because it can be used to compromise entire networks and is difficult to detect.
