Answer 37

Telnet: Telnet is a protocol used for communicating with a remote host (via port 23) on a network using a command-line terminal. rlogin enables an attacker to log into a network machine remotely via a TCP connection. Neither of these protocols provides encryption; therefore, data traveling between clients connected through any of these protocols are in plaintext and vulnerable to sniffing. Attackers can sniff keystrokes, including usernames and passwords.

Question 38

In which of the following OSI layers do sniffers operate and perform an initial compromise?

Answer 38

The data link layer is the second layer of the OSI model. In this layer, data packets are encoded and decoded into bits. Sniffers operate at the data link layer and can capture packets from this layer. Networking layers in the OSI model are designed to work independently of each other; thus, if a sniffer sniffs data in the data link layer, the upper OSI layers will not be aware of the sniffing.

Answer 46

Session Hijacking: Session hijacking is an attack in which an attacker takes over a valid Transmission Control Protocol (TCP) communication session between two computers. Because most types of authentication are performed only at the start of a TCP session, an attacker can gain access to a machine while a session is in progress. Attackers can sniff all the traffic from established TCP sessions and perform identity theft, information theft, fraud, etc.

Question 47

In which of the following session hijacking phases does an attacker break the connection to the victim’s machine by knowing the next sequence number (NSN)?

Answer 47

Session Desynchronization: Break the connection to the victim’s machine. It is easy to accomplish this attack if the attacker knows the next sequence number (NSN) used by the client. A session can be hijacked by using that sequence number before the client uses it.

Question 48

Which of the following countermeasures should be followed to defend against session hijacking?

Answer 48

Industrial Demilitarized Zone: The demilitarized zone is a barrier between the manufacturing zone (OT systems) and enterprise zone (IT systems). This zone is created to inspect overall architecture. If any errors or intrusions compromise the working systems, the IDMZ holds the error and allows production to be continued without interruption.

Question 87

James, an attacker, targeted an industrial network to halt the operations of SCADA devices. He exploited a stack-based buffer overflow vulnerability in the operational software that resulted in a crash of the program that operates SCADA devices. Which of the following vulnerabilities is exploited by James in the above scenario?

Answer 87

Memory corruption the vulnerability that may occur in a computer system when its memory is altered without an explicit assignment. The contents of a memory location are modified due to programming errors which enable attackers to execute an arbitrary code.

Question 88

Justin, a security professional, performs continuous monitoring and anomaly detection of the OT systems in his organization to thwart any type of malfunctioning of the OT devices. For this purpose, he deployed a tool that ensures the reliability of networks and avoids downtime and disruption of service continuity. Identify the tool utilized by Justin to protect the OT systems and networks.

Answer 88

Flowmon processes network telemetry data including IP flows and raw packets, which it collects from a variety of network devices. Dedicated proprietary sensors called Flowmon Probes can be used to improve performance, increase data granularity, and enrich the flow data with L7-information.

Question 89

Which of the following cloud computing models provides penetration testing, authentication, intrusion detection, and anti-malware services to corporate infrastructure in a cost-effective way?

Answer 89

Security-as-a-service service provider integrates their security services into a corporate infrastructure on a subscription basis more cost-effectively than most individuals or corporations can provide on their own when the total cost of ownership is considered

Question 90

Which of the following entities in the NIST cloud deployment reference architecture is a party that performs an independent examination of cloud service controls to express an opinion and verify adherence to standards through a review of the objective evidence?

Answer 90

Cloud Auditor: A cloud auditor is a party that performs an independent examination of cloud service controls to express an opinion thereon. Audits verify adherence to standards through a review of the objective evidence.

Question 91

Which of the following components in the container network model encompasses the container network stack configuration to manage container interfaces, routing tables, and DNS settings?

Answer 91

Sandbox: Sandbox comprises the container network stack configuration for the management of container interfaces, routing tables, and domain name system (DNS) settings.

Question 92

Which of the following components in Docker architecture refers to locations where images are stored and pulled whenever required?

Answer 92

Docker Registries is a storage and distribution system for named Docker images. The same image might have multiple different versions, identified by their tags. A Docker registry is organized into Docker repositories , where a repository holds all the versions of a specific image.

Question 93

Which of the following cloud computing threats is caused by incomplete and non-transparent terms of use and hidden dependencies created by cross-cloud applications?

Answer 93

Supply chain failure

Question 94

Smith, a professional hacker, was assigned to perform an attack on AWS S3 buckets. He employed a tool to brute-force AWS S3 buckets with different permutations to breach the security mechanism and inject malware into the bucket files. Identify the tool employed by Smith in the above scenario.

Answer 94

lazys3 A Ruby script to bruteforce for AWS s3 buckets using different permutations.

Question 95

Which of the following countermeasures helps security teams protect the cloud environment against online threats?

Answer 95

Verify one’s own cloud in public domain blacklists

Question 96

Which of the following countermeasures helps security professionals secure the cloud network from cryptojacking attacks?

Answer 96

Review all third-party components used by the company’s websites

Question 97

Smith, a certified pen tester, was assigned to perform penetration testing on the organization's network. As he knew that penetration testing might harm the network, he followed a guideline that involves collecting sufficient evidence to determine whether any vulnerabilities exist in the network. Which of the following guidelines did Smith follow in the above scenario?

Answer 97

Use indirect testing

Question 98

Identify the penetration testing approach representing an adversarial goal-based assessment where the pen tester mimics a real attacker and targets an environment.

Answer 98

Red-team-oriented penetration testing approach: This approach is an adversarial goal-based assessment in which the pen tester must mimic a real attacker and target an environment.

Question 99

Identify the pen testing operation that involves gathering all the information significant to security vulnerabilities and testing the targeted environment, including network configuration, topology, hardware, and software.

Answer 99

Performing the Penetration Test: Each company ensures that the processes they implement for penetration testing are appropriate. Therefore, proper methodologies must be used for performing a good penetration test. The tester is responsible for checking the system for any existing or new applications, networks, and systems, in addition to checking whether the system is vulnerable to a security risk that could allow unauthorized access.

Question 100

Identify the penetration testing methodology compiled by Pete Herzog and a standard set for penetration testing to achieve security metrics.

Answer 100

Open Source Security Testing Methodology Manual: The Open Source Security Testing Methodology Manual was compiled by Pete Herzog. It is a standard set for penetration testing to achieve security metrics.
