A previously unknown security flaw that has not yet been patched by vendors
A vulnerability that only occurs on the last day of support
A bug that is common in all software versions
A weakness found only in legacy systems
Zero-day vulnerabilities are dangerous because they are unknown to the software maker and remain unpatched. Attackers can exploit these flaws before a fix is released, increasing risk.
What does the principle of least privilege ensure in a secure environment?
Users are granted only the minimum access necessary to perform their functions
All users receive administrative level permissions
Passwords are shared among team members for convenience
System access is completely restricted for all users
The principle of least privilege minimizes potential damage by limiting users' access rights to only what is essential. This approach reduces the risk of accidental or deliberate misuse of access.
Which technique can attackers use to undermine multifactor authentication?
Exploiting human behavior through social engineering to obtain one of the authentication factors
Using a faster internet connection to bypass authentication
Encrypting the authentication data during transmission
Installing additional firewall software
Attackers often resort to social engineering techniques to deceive users into revealing elements of their multifactor authentication. This bypasses technological safeguards by exploiting human vulnerabilities.
What is ransomware and how does it affect victims?
Malware that encrypts a victim's data and demands payment for decryption
Software that cleans viruses from a system automatically
A tool used to speed up computer performance
An application that monitors network traffic for security threats
Ransomware locks users out of their data by encrypting files, then extorts money for the decryption key. This type of attack can cause serious operational and financial disruptions.
Which protocol is primarily used to secure communications on websites, as seen in HTTPS?
TLS/SSL, which encrypts data during transmission
FTP, which transfers files without encryption
SMTP, which is used for sending emails
HTTP, which transmits unencrypted data
TLS and SSL are cryptographic protocols that provide secure communication over networks. They are the backbone of secure web browsing, enabling HTTPS to protect data in transit.
How do intrusion detection systems (IDS) help maintain network security?
They monitor network traffic for suspicious activities and alert administrators to potential breaches
They automatically repair infected files on a computer
They replace antivirus programs on network endpoints
They physically secure server rooms from unauthorized entry
IDS tools are designed to continuously analyze network traffic for signs of malicious behavior. By alerting security teams to anomalies, they help prevent or mitigate attacks.
What is the primary purpose of conducting a risk assessment in cybersecurity?
To identify, evaluate, and prioritize risks so that appropriate security measures can be implemented
To completely eliminate all cyber threats from the environment
To increase the number of active vulnerabilities for testing purposes
To replace cybersecurity policies with automated scripts
Risk assessments are a critical process in cybersecurity management. They help organizations understand their vulnerabilities and decide which measures will best mitigate potential threats.
Which of the following best describes a man-in-the-middle (MITM) attack?
An attack where the adversary intercepts and may alter communications between two parties without their knowledge
An attack that only targets wireless network devices
An attack that damages physical network infrastructure
An attack using phishing emails exclusively to compromise communication
A man-in-the-middle attack occurs when an attacker secretly intercepts, relays, or alters communication between two parties. This can result in data theft or manipulation without immediate detection.
How does Public Key Infrastructure (PKI) enhance cybersecurity practices?
By providing a framework for encryption, key distribution, and digital signatures
By eliminating the need for traditional antivirus solutions
By physically isolating computer networks from the internet
By automatically updating all operating systems without user intervention
PKI establishes trust in digital communications through the use of certificates and encryption keys. It underpins many secure transactions by ensuring authenticity and data integrity.
Which network scanning tool is widely used for vulnerability assessment?
Nmap
Photoshop
WordPress
Excel
Nmap is a popular open-source tool that helps security professionals discover hosts and services on a network. Its ability to identify open ports and system vulnerabilities makes it invaluable for network security audits.
What is a distinguishing feature of advanced persistent threats (APTs)?
They conduct long-term, stealthy operations to infiltrate and extract data from networks
They occur only during a system's routine maintenance period
They are easily detected and quickly mitigated by standard antivirus software
They rely solely on brute force methods to compromise systems
APTs are characterized by their persistence, subtlety, and long-term focus. Attackers behind APTs often remain undetected for extended periods while carefully extracting valuable data.
How does implementing regular software updates contribute to enhanced cybersecurity?
