質問 # 92
On which website can you check if your email account has been compromised?
正解：A
解説：
The correct platform used to check whether an email address has been involved in known data breaches is
https://haveibeenpwned.com
, making option B the correct answer. This service aggregates data from publicly disclosed breaches and allows users to verify if their credentials have been exposed.
Understanding data breaches is a key part of current security trends, as credential leaks remain one of the most common causes of account compromise. Ethical hackers, security professionals, and even everyday users use such services to assess exposure and take corrective action, such as changing passwords or enabling multi-factor authentication.
Option A, Facebook, is a social media platform and does not provide breach-checking services. Option C is unrelated and does not serve any cybersecurity or breach-monitoring function.
From an ethical hacking standpoint, breach-awareness tools help reinforce proactive defense strategies. They raise awareness of credential reuse risks and demonstrate how leaked data can be weaponized in phishing, credential stuffing, and social engineering attacks.
Monitoring breach exposure is not hacking; it is a defensive security measure. Ethical hackers use this knowledge to educate organizations on password hygiene, the importance of unique credentials, and the implementation of identity protection controls. Staying informed about breaches is essential in modern cybersecurity environments.
質問 # 93
What is a firewall?
正解：A
解説：
A firewall is a cornerstone master information security control that serves as a protective barrier between a trusted internal network and untrusted external networks, such as the internet. Its primary function is to monitor and control incoming and outgoing network traffic based on a predetermined set of security rules. By analyzing packet headers-specifically IP addresses, port numbers, and protocols-the firewall determines whether to "allow," "block," or "drop" a connection attempt.
Firewalls can be implemented as hardware appliances, software installed on a host, or a combination of both.
They generally fall into several categories:
* Packet Filtering Firewalls: These examine individual packets in isolation and are the most basic form of protection.
* Stateful Inspection Firewalls: These track the state of active connections, ensuring that incoming traffic is only allowed if it is a response to a legitimate outgoing request.
* Next-Generation Firewalls (NGFW): These go beyond simple port/IP filtering by performing "Deep Packet Inspection" (DPI) to identify specific applications and even filter out malware or malicious commands within the traffic.
In the pentesting process, the firewall is the first major obstacle a tester encounters. It defines the "perimeter" of the organization. An ethical hacker will use port scanning to identify which "holes" exist in the firewall's ruleset. For defenders, a properly configured firewall is essential for implementing "Default Deny" policies, where all traffic is blocked unless it is explicitly permitted. This significantly reduces the attack surface by ensuring that services like database ports are never exposed to the public internet. While a firewall is not a substitute for antivirus (Option A) or an exploit method (Option B), it is the most vital tool for regulating network access and preventing unauthorized intrusions.
質問 # 94
Updating the Package Index
正解：B
解説：
Updating a Debian-based Linux distribution like Kali Linux is a fundamental administrative task that ensures the system has the latest metadata regarding available software packages. The command sudo apt-get update is the standard method used within the console to synchronize the local package index with the remote repositories. When this command is executed, the apt (Advanced Package Tool) utility reads the /etc/apt
/sources.list file to identify the URLs of the repositories. It then connects to these servers and downloads the latest package lists, which contain information about version numbers, dependencies, and descriptions of every software package available for that specific distribution version.
Using sudo is mandatory because modifying the package database requires root-level (administrative) privileges. It is important to distinguish between "updating" and "upgrading." The update command does not actually install or change any existing software on the machine; it simply refreshes the "table of contents" so the system knows which packages have newer versions waiting to be installed. Once the update is complete, a secondary command-typically sudo apt-get upgrade or sudo apt-get dist-upgrade-is required to actually download and apply the new software versions to the system. In the context of ethical hacking, keeping a Kali Linux instance updated is critical for security and tool functionality. Outdated systems may lack the latest exploit modules in frameworks like Metasploit or may contain vulnerabilities that could be exploited by an adversary if the hacking machine is connected to a hostile network. Proper maintenance of the terminal environment ensures that penetration testing tools operate with the highest degree of reliability and that the researcher's environment remains secure against known threats.
質問 # 95
What is the best practice to protect against malware?
正解：A
解説：
The most effective and fundamental master information security control for protecting against malicious software is the installation and regular updating of antivirus software. Malware, which includes viruses, Trojans, and ransomware, is specifically designed to damage, infect, or steal data from a computer system without the owner's consent. Antivirus software serves as a critical defense layer by scanning files and monitoring system behavior to detect and neutralize these threats before they can execute their malicious payload.
However, simply having the software installed is insufficient; it must be kept up to date. Hackers and malware developers are constantly creating new "variants" of software designed to bypass existing security signatures.
Modern antivirus programs receive frequent updates containing the latest "definitions" or "signatures" of known malware, as well as heuristic analysis updates that help identify suspicious behavior from previously unknown threats.
Beyond antivirus, protecting against malware requires a multi-layered approach that includes administrative and technical controls. This involves the "periodic updating of the operating system" to patch vulnerabilities that malware might exploit to gain entry. It also requires "Security Awareness," where users are taught to avoid clicking on suspicious links or sharing credentials, as these are common infection vectors used in social engineering attacks. By combining automated technical defenses (antivirus) with proactive maintenance (patching) and user education, an organization can significantly mitigate the risk of a malware infection. This holistic strategy ensures that even if one control fails, other layers of defense are in place to safeguard the integrity and confidentiality of the organization's data.
質問 # 96
Can the ssh protocol be breached?
正解：C
解説：
Secure Shell (SSH) is a cryptographic network protocol used for secure operating system logins and file transfers over insecure networks. While the protocol itself is built on strong encryption, it is not
"impenetrable". Like any technology, SSH can be breached if it is misconfigured or if the human elements managing it fail.
Attackers use several methods to breach SSH services:
* Brute Force and Dictionary Attacks: If an SSH server allows password authentication and the user has a weak password, an attacker can use automated tools to guess the credentials. This is the most common form of SSH breach.
* Key Theft: SSH often uses "Private Keys" for authentication. If an attacker gains access to a user's computer and steals an unencrypted private key, they can log into the server without a password.
* Exploiting Vulnerabilities: While rare, flaws can be found in specific implementations of the SSH server software (like OpenSSH). If the server is not regularly updated, an attacker might use a "zero- day" or known exploit to bypass authentication.
* Man-in-the-Middle (MITM): If a user ignores a "Host Key Verification" warning when connecting, an attacker could be intercepting their connection.
To harden SSH against these threats, ethical hackers recommend several controls: disabling root login, changing the default port (22) to a non-standard one to avoid automated bots, enforcing the use of SSH keys instead of passwords, and implementing "Fail2Ban" to lock out IP addresses that attempt too many failed logins. The security of SSH depends entirely on the rigor of its implementation.
