Question 26: You are about to initiate a penetration test. You want first to gather the email IDs of the employees. Which of the following tool should you use?

To gather email IDs of employees for a penetration test, you should utilize a reliable tool called theHarvester. This open-source tool specializes in extracting various information, including emails, employee details, sub-domains, and hostnames. By utilizing theHarvester, you can employ different search engines like Google, Bing, as well as platforms like LinkedIn, to efficiently collect the required email IDs of employees. Therefore, the appropriate tool for this task is theHarvester.

Question 27: Which protocol should be used to secure voice and video?

To secure voice and video transmissions, the recommended protocol to use is SRTP, which stands for Secure Real-time Transport Protocol. SRTP is specifically designed to ensure the confidentiality, integrity, and authenticity of real-time voice and video data. Its main purpose is to protect sensitive information communicated through voice and video channels from unauthorized access or tampering. SRTP is widely used in various applications where secure voice and video communications are crucial, providing a reliable and robust solution for protecting these types of data transmissions.

Question 28: What does NIC teaming provide along with redundancy?

NIC teaming provides both redundancy and load balancing. In addition to ensuring that network connectivity remains uninterrupted by linking multiple network interface cards (NICs) together, NIC teaming also distributes incoming network traffic across these NICs. This load balancing mechanism helps to optimize network performance and prevent any single NIC from becoming overwhelmed with traffic.

Question 29: What is the definition of False Rejection Rate (FRR)?

False Rejection Rate (FRR) is a metric used in biometric systems to evaluate the performance of authentication processes. FRR measures the percentage of times when a legitimate user is wrongly denied access or fails to be authenticated by the system.

In other words, FRR occurs when the system incorrectly rejects or denies access to genuine users. This can happen due to various reasons such as technical issues, imperfect algorithms, or the user’s biometric characteristics not matching the stored template accurately.

It is important to minimize the False Rejection Rate in biometric systems as a high FRR can result in frustration and inconvenience for legitimate users who are denied access, leading to a poor user experience. Consequently, system administrators and developers aim to strike a balance between security and usability by setting an optimal threshold for the FRR.

To evaluate the overall performance of a biometric system, FRR is often compared with the False Acceptance Rate (FAR). FAR measures the percentage of times when an illegitimate or unauthorized user is incorrectly granted access or authenticated successfully. By analyzing the relationship between FRR and FAR, the crossover error rate (CRR) can be determined, which represents the point where FRR and FAR are equal.

However, it is important to note that FRR and FAR are not the only factors to consider when evaluating the effectiveness of a biometric system. Other metrics, such as accuracy, reliability, and usability, should also be taken into account to ensure the system meets the desired performance standards.

Question 30: What is the biggest challenge in code reuse?

The biggest challenge in code reuse is the careful planning and development time required. When code is to be reused in future applications, it needs to be meticulously designed and implemented to ensure its effectiveness.

One possible misconception is that code reuse is difficult to test (Option A). However, during the initial development of the code, it undergoes thorough testing. When reused, it primarily requires testing for integration rather than individual functionality.

Another incorrect choice is that code reuse introduces more bugs (Option C). In reality, code that is intended for reuse is already tested and proven to be reliable. Therefore, it typically has fewer bugs or even none when compared to newly developed code.

Similarly, code reuse is often not difficult to integrate (Option D). Since code is developed with its reusability in mind, the integration process is usually streamlined and purposefully designed to facilitate reuse.

In summary, the most significant challenge in code reuse is the additional time and effort required for careful planning and development.

Question 31: Which environment should you use for integration testing and measuring application performance?

For integration testing and measuring application performance, it is recommended to utilize the testing environment, which is separate and isolated from the development environment. This dedicated testing environment allows you to conduct comprehensive integration testing of the different components you have developed, ensuring they seamlessly work together. Additionally, this environment provides an ideal space for accurately evaluating the performance of your application.

Question 32: Which type of attack reverses a cryptography hash function?

A type of attack that reverses a cryptographic hash function, thus revealing the original password, is known as a rainbow table attack. This attack utilizes a specially prepared table called a rainbow table, which stores precomputed hashes for various passwords. When an attacker gains access to the password hashes from a target system, they can compare these hashes with the entries in the rainbow table to retrieve the corresponding original passwords. The attacker does not need to go through the process of trying different passwords, but rather relies on the precomputed hashes stored in the rainbow table. This way, the rainbow table attack exploits the weakness of the hash function, making it possible to reverse-engineer the original password.

Question 33: What can be the carrier for a backdoor trojan into a system?

A backdoor trojan can be delivered into a system through various means. One possible carrier for a backdoor trojan is a fileless malware, which does not rely on the presence of a specific file or executable but rather exploits system vulnerabilities directly. Another carrier could be a worm, a self-replicating malware that can spread across networks and systems, potentially acting as a vehicle for a backdoor trojan. Additionally, a trojan horse can also serve as a carrier for a backdoor trojan. This type of malware is disguised as a legitimate or desirable file or program, tricking users into unknowingly installing it and granting unauthorized access to the attacker. It is important to note that a logic bomb, a form of malware that activates under specific conditions or triggers, may not typically act as a carrier for a backdoor trojan, as its primary function is to cause harm or disruption rather than provide unauthorized access to a system.

Question 34: Which type of social engineering attack has occurred if someone creates a Facebook page with your name and contains your information and photos?

In this case, the social engineering attack that has occurred is a form of identity theft. The attacker has created a Facebook page using your name and has included your personal information and photos without your knowledge or consent. This malicious act involves the unauthorized use of someone else’s identity with the intention to deceive or harm others.

Question 35: What type of attack has occurred if you were taken to a website after misspelling its name and your system becomes unstable?

If you were taken to a different website after misspelling the name of the website you intended to visit and your system becomes unstable afterwards, it is likely that a typosquatting attack has occurred.

Typosquatting is a type of attack where cyber attackers register intentionally misspelled domain names that are similar to popular and legitimate domain names. For example, they may register a domain name such as gogle.com or gooogle.com instead of Google.com. By doing so, they create malicious websites that mimic the legitimate ones.

When you accidentally visit a typosquatting website, it can lead to various malicious activities that may compromise the security of your system. These attacks can include infecting your device with malware, stealing personal information, or redirecting you to phishing websites that attempt to trick you into revealing sensitive data.

Therefore, in the scenario described, the instability experienced by your system suggests that you were most likely a victim of a typosquatting attack. It is important to be cautious when typing website addresses and to verify the domain name before entering any sensitive information or downloading any files.

Question 36: You are about to initiate a penetration test. Instead of using theHarvester tool, you want to use an alternative to enumerate subdomains. Which of the following tools can serve as an alternative to theHarvester?

When initiating a penetration test and looking for an alternative tool to enumerate subdomains instead of theHarvester, a suitable option is sublist3r.

Explanation:

Option A: Cuckoo is an open-source sandbox primarily used for malware analysis. It is not intended for subdomain enumeration and would not serve as a replacement for theHarvester.

Option B: Metasploit is a widely used penetration testing framework that provides a range of functionalities for exploits and vulnerability testing. While it is a powerful tool, it does not specialize in subdomain enumeration and would not be a direct alternative to theHarvester.

Option C: sn1per is an information gathering and penetration testing platform specifically designed for discovering attack surfaces and managing risks. Though it is a useful tool for reconnaissance, it is not primarily built for subdomain enumeration and would not be a direct alternative to theHarvester.

Option D: The correct answer is D. sublist3r is a tool specifically created for subdomain enumeration and can effectively serve as an alternative to theHarvester. It is designed to discover subdomains through various sources, providing an extensive enumeration capability in penetration testing scenarios.

By utilizing sublist3r as a substitute for theHarvester, one can effectively enumerate subdomains during a penetration test, expanding the scope of the assessment and potentially identifying additional targets of interest.
