What is phishing?
A fraudulent attempt to obtain sensitive information via deceptive emails or websites
A method of scanning network vulnerabilities
A protocol for secure file transfer
A firewall configuration tool
Phishing involves sending deceptive messages to trick recipients into revealing sensitive data. It often uses fake emails or websites that appear legitimate to capture credentials or personal information.
Which best describes the principle of least privilege?
Granting users only the minimum permissions needed to perform their tasks
Allowing all users to share administrator accounts
Granting full access to all resources for new employees
Removing all user permissions after initial setup
The principle of least privilege restricts user permissions to only what is necessary for their roles. This minimizes the potential damage from accidents or malicious actions by limiting access to sensitive resources.
What is the best practice for disposing of sensitive paper documents?
Shredding documents before disposal
Throwing documents in regular trash bins
Scanning and emailing them for storage
Leaving them on a desk for recycling
Shredding physically destroys the paper, making it unreadable and protecting sensitive information. Regular trash disposal risks unauthorized retrieval of confidential data.
Which of the following is an example of two-factor authentication?
Entering a password followed by a one-time SMS code
Using only a username and password
Answering security questions alone
Entering a PIN only
Two-factor authentication combines something you know (a password) with something you have (a one-time code sent to your device). This adds an extra layer of security beyond a single credential.
Which of the following is a common physical security barrier for a government facility?
Perimeter fence with controlled access points
Antivirus software on workstations
Employee code of conduct
Password complexity rules
Perimeter fences control access to facility grounds and deter unauthorized entry. Physical barriers are essential for protecting critical infrastructure before digital or administrative controls come into play.
What is the best practice when accessing sensitive resources over public Wi-Fi?
Use a VPN before accessing any sensitive resources
Disable all security features to improve speed
Rely on verifying the network name only
Share your passwords with the network administrator
A VPN encrypts data between your device and the endpoint, preventing eavesdropping on public networks. Other measures alone do not ensure confidentiality or protect against malicious hotspots.
To access classified government information, what is required?
Both appropriate security clearance and a valid need-to-know
Only a valid need-to-know
Only a security clearance
Just a manager's approval
Classified information is protected by both clearance level and the need-to-know principle. Even with clearance, access is restricted to individuals whose duties require that specific information.
What is the first step in conducting a risk assessment?
Identifying and valuing critical assets
Implementing security controls
Conducting penetration testing
Developing a business continuity plan
Risk assessments begin with identifying and valuing assets to understand what needs protection. Without knowing asset value, it is impossible to evaluate threat likelihood and impact accurately.
What does a SIEM system do?
Collects and analyzes security logs for real-time monitoring and alerts
Serves as a physical barrier for network equipment
Performs automated password cracking
Acts as a wireless encryption standard
SIEM stands for Security Information and Event Management and centralizes log data for correlation, analysis, and alerting. It helps security teams detect anomalies and respond quickly to potential breaches.
Which best describes a supply chain attack?
Exploiting a vendor's update mechanism to deliver malware to customers
Attacking a system directly via phishing
Brute forcing user credentials repeatedly
Overloading network bandwidth to disrupt service
A supply chain attack targets third-party vendors or software providers to introduce malicious code that reaches end users. This method bypasses direct defenses around the target organization.
What is meant by 'defense in depth'?
Implementing multiple, redundant security controls across different layers
Using a single, highly specialized firewall
Allowing unrestricted network access during business hours
Disabling antivirus software to prevent conflicts
Defense in depth uses overlapping security measures so that if one control fails, others still protect the asset. Layers may include physical, technical, and administrative controls.
Which scenario represents an insider threat?
A disgruntled employee exfiltrating confidential files via USB
An unknown hacker exploiting a public-facing server vulnerability
Malware delivered to a user via a phishing email
A distributed denial-of-service attack from external bots
Insider threats originate from individuals within the organization who abuse their access rights. This scenario illustrates an employee intentionally removing sensitive data.
What is a key benefit of network segmentation?
It restricts lateral movement of attackers within the network
It increases network latency to discourage intruders
It shares all data across all subnets
It merges different networks to simplify administration
Segmentation divides a network into isolated segments so that if one segment is compromised, attackers cannot easily move to others. This limits potential damage and aids in containment.
What characterizes a brute force attack?
Trying every possible combination of credentials until one succeeds
Injecting malicious scripts into web forms
Intercepting and altering network packets
Exploiting buffer overflow vulnerabilities in applications
Brute force attacks systematically attempt all possible passwords or keys until they find the correct one. They rely on computational power rather than exploiting software flaws.
Why is regular patch management critical in national security environments?
It fixes known vulnerabilities to reduce risk exposure
It intentionally degrades system performance
It removes all security logs from servers
It automatically increases password complexity
Patching addresses software flaws that attackers could exploit to gain unauthorized access. Keeping systems up to date minimizes the window of exposure to known threats.
A critical system has an unpatchable vulnerability due to compatibility constraints. What is the best mitigation strategy?
Implement compensating controls such as network segmentation and enhanced monitoring
Ignore the vulnerability until a patch becomes available
Rely solely on employee awareness training
Delete all system logs related to the vulnerability
When patching is not feasible, compensating controls like isolating the system and adding intrusion detection limit exploitation. Enhanced monitoring helps detect any attempts to leverage the vulnerability.
An air-gapped control network is still at risk because employees use USB drives. Which control reduces this threat?
Enforce a removable media policy and disable unauthorized USB ports
Allow all devices as long as they are scanned externally
Encourage users to share USB drives only within their department
Replace USB ports with additional Ethernet ports
Disabling or restricting USB ports prevents malware introduction via removable media. A strict policy ensures only approved devices can connect after proper scanning and authorization.
To ensure end-to-end integrity of security logs sent to a remote SIEM, which mechanism should be used?
Digital signatures on log files using cryptographic keys
Transmitting logs over an unsecured channel
Storing logs in plain text on a local workstation
Relying solely on periodic manual log reviews
Digital signatures allow recipients to verify that logs have not been altered in transit by validating the cryptographic signature. This provides integrity assurance beyond simple encryption.
In a risk matrix, a vulnerability with low likelihood but high impact is classified as what level of risk?
Medium risk
Low risk
High risk
Critical risk
Risk matrices combine likelihood and impact. A low-probability, high-impact event typically falls into a medium risk category because the impact elevates its priority despite its low likelihood.
What does the TEMPEST standard protect against?
Compromising electromagnetic emanations from electronic equipment
Unauthorized software installations on servers
Physical intrusion into secure facilities
Phishing attacks via email
TEMPEST focuses on shielding or reducing electromagnetic emissions that could be intercepted to reconstruct sensitive data. It addresses the risk of eavesdropping on electronic signals.
