Nmap is the primary tool used forport scanning, making option B the correct answer. Port scanning is a core activity during the reconnaissance and scanning phases of penetration testing, where the goal is to identify open, closed, or filtered ports on target systems.

Nmap allows ethical hackers to discover which services are running, their versions, and potential misconfigurations. It supports multiple scan types, including TCP SYN scans, UDP scans, and service detection scans, making it highly versatile and efficient.

Option A is incorrect because Metasploit is primarily an exploitation framework, not a dedicated port scanner. Option C is incorrect because Shodan is an internet-wide search engine, not a direct scanning tool used against specific targets.

Understanding port scanning is essential for identifying attack surfaces. Open ports often expose services that may contain vulnerabilities or misconfigurations. Ethical hackers use Nmap responsibly to map networks and guide further testing.

From a defensive perspective, regular port scanning helps organizations identify unnecessary services and enforce least-exposure principles. Nmap remains one of the most fundamental tools in ethical hacking and network security.

Yes, it is possible to clone a web page, making option B the correct answer. Web page cloning involves copying the structure, appearance, and content of a legitimate website, often for malicious purposes such as phishing or credential harvesting.

Attackers use cloning to trick users into believing they are interacting with a trusted site. Ethical hackers study this technique to demonstrate the risks of social engineering and help organizations implement defenses such as user education, domain monitoring, and email security controls.

Cloning does not typically require exploiting vulnerabilities; instead, it abuses publicly available content and human trust. This makes it a powerful and common attack vector.

Understanding web page cloning helps organizations recognize phishing threats and protect users from impersonation attacks. Ethical hackers use controlled demonstrations to raise awareness and improve detection capabilities.

Malware, short for "malicious software," is a broad category of intrusive software developed by cybercriminals to compromise the confidentiality, integrity, or availability of a victim's data. It encompasses a wide variety of threats, including viruses, worms, Trojans, ransomware, and spyware. The defining characteristic of malware is that it is installed and executed on a system without the explicit consent or knowledge of the owner, with the primary intent of causing harm, stealing sensitive information, or gaining unauthorized access.

Managing malware as a security threat involves understanding its infection vectors and payload behaviors. Viruses attach themselves to legitimate files and spread through user interaction, while worms are self-replicating and spread across networks automatically by exploiting vulnerabilities. Trojans disguise themselves as useful programs to trick users into executing them, often opening "backdoors" for further exploitation. Ransomware, one of the most profitable forms of malware today, encrypts a user's files and demands payment for the decryption key.

Ethical hackers study malware to develop better detection signatures and behavioral analysis techniques. By analyzing how malware obfuscates its code or communicates with a Command and Control (C2) server, security professionals can implement better endpoint protection and network monitoring. Protecting against malware requires a multi-layered defense strategy, including up-to-date antivirus software, regular system patching, and user awareness training to prevent the execution of suspicious attachments or links. Understanding the diverse nature of malware is essential for any cybersecurity expert, as it remains the primary tool used by attackers to gain a foothold within targeted organizations.

From a cybersecurity and ethical hacking perspective, the most accurate answer isoption C: yes, all computers are hackable. This does not mean that all systems are easily compromised, but rather thatno system is 100% secureunder all circumstances.

Security is a matter of risk management, not absolute prevention. Even fully patched systems with strong security controls may be vulnerable to zero-day exploits, misconfigurations, supply-chain attacks, physical access threats, or human factors such as social engineering. Ethical hackers assess these risks to determine how systems could be compromised under realistic threat scenarios.

Option A is incorrect because even updated systems with minimal exposure can still be attacked through advanced techniques. Option B is incorrect because hacking is not always easy or without complications; strong defenses significantly increase the difficulty.

Understanding this concept is critical in modern security strategy. Ethical hacking promotesdefense in depth, continuous monitoring, regular testing, and user awareness rather than reliance on a single control.

Acknowledging that all systems are potentially hackable encourages proactive security practices, timely patching, strong authentication, network segmentation, and incident response planning. Ethical hackers help organizations identify weaknesses early, reduce risk, and improve resilience against evolving cyber threats.
