What is the primary function of a network firewall in cyber defense?
Manage user permissions
Block unauthorized network traffic
Detect malware signatures
Encrypt data at rest
A firewall's main role is to filter and block unauthorized network traffic based on defined policy rules. It does not perform malware detection, encryption, or user account management.
Which component is typically responsible for monitoring and managing Air Force network performance?
Security Operations Center (SOC)
Help Desk
Red Team
Network Operations Center (NOC)
The Network Operations Center (NOC) oversees network performance and availability. The SOC focuses on security events, while help desks and red teams serve different support and testing roles.
What best defines mission assurance in cyber operations?
Running vulnerability scans weekly
Encrypting all communications channels
Ensuring critical functions remain available under cyber threats
Performing daily data backups only
Mission assurance focuses on maintaining availability, integrity, and confidentiality of essential operations even under adverse conditions. While encryption, backups, and scans support security, they do not alone guarantee mission continuity.
Which port does HTTPS use by default?
80
443
25
22
HTTPS uses TCP port 443 by default to secure web traffic with SSL/TLS encryption. Port 80 is for HTTP, 22 for SSH, and 25 for SMTP.
What describes two-factor authentication (2FA)?
Logging in with a password only
Entering two different passwords sequentially
Using a single biometric scan
Using a password and a one-time code from a separate device
Two-factor authentication requires something you know (a password) plus something you have (a one-time code generator). Two passwords, biometrics alone, or single-factor methods do not meet 2FA criteria.
Which vulnerability involves injecting malicious SQL statements into input fields?
SQL Injection
Cross-Site Request Forgery (CSRF)
Buffer Overflow
Cross-Site Scripting (XSS)
SQL Injection allows attackers to manipulate database queries via crafted input. XSS targets web pages, CSRF abuses authenticated sessions, and buffer overflows exploit memory boundaries.
Which configuration practice reduces the attack surface on a network device?
Enable Telnet for remote access
Leave development features enabled
Use default credentials
Disable unused ports and services
Disabling unused ports and services prevents attackers from exploiting unnecessary functions. Enabling Telnet, using defaults, or leaving extra features active increases risk.
Which tool is commonly used for active network scanning?
Wireshark
Metasploit
Nmap
John the Ripper
Nmap is widely used to discover hosts and services on a network. Wireshark captures packets, Metasploit exploits, and John the Ripper cracks passwords.
Which phase comes first in the standard incident response cycle?
Eradication
Preparation
Recovery
Containment
Preparation is the initial phase where policies, tools, and training are established. Containment, eradication, and recovery follow once an incident occurs.
What is the principle of least privilege?
Granting users only the access they need to perform their duties
Revoking all administrative rights
Sharing credentials among team members
Allowing users full access by default
Least privilege means users receive only the permissions necessary for their roles. Default full access, revoking all rights, or credential sharing do not align with this security principle.
What is the main function of a Security Information and Event Management (SIEM) system?
Deploy software patches automatically
Perform vulnerability assessments
Aggregate and analyze log data for security events
Encrypt network traffic
A SIEM collects, correlates, and analyzes logs to detect and alert on security incidents. It does not directly patch, assess vulnerabilities, or encrypt traffic.
What role does the Security Operations Center (SOC) play?
Monitor and respond to security incidents
Design network architectures
Provide end-user help desk support
Develop web applications
The SOC is responsible for continuous monitoring and responding to security events. Architecture design, web development, and help desk support are handled by other teams.
When securing a new server, which default configuration change is most critical?
Change or disable default passwords
Open all firewall ports for testing
Install extra diagnostic tools
Enable guest account access
Changing default credentials is essential to prevent unauthorized access. Enabling guest accounts, adding unnecessary tools, or opening all ports increase security risks.
How does mission assurance apply during a contingency operation?
Requires daily full system rebuilds
Ensures essential functions continue under degraded conditions
Mandates real-time encryption of all logs
Guarantees no data loss ever occurs
Mission assurance ensures critical capabilities persist even when normal operations are disrupted. It does not promise zero data loss, forced log encryption, or constant system rebuilds.
What key difference separates vulnerability scanning from penetration testing?
Scanning uses manual methods; penetration testing is always automated
Scanning encrypts data; penetration testing decrypts data
Scanning identifies potential flaws; penetration testing attempts to exploit them
Scanning bypasses security controls; penetration testing does not
Vulnerability scans detect possible weaknesses, while penetration tests actively exploit vulnerabilities to assess real-world impact. The other options mischaracterize their roles.
Which technique is most effective at mitigating Cross-Site Scripting (XSS) vulnerabilities?
Use a stronger password policy
Encrypt user data in transit
Disable HTTPS enforcement
Validate and encode all user-supplied input before output
Proper input validation and output encoding prevent malicious scripts from executing in a user's browser. Encryption, HTTPS, and password policies do not directly stop XSS attacks.
During incident response, which action best preserves the chain of custody for digital evidence?
Document every individual who accesses the evidence and actions taken
Delete nonessential log files to reduce noise
Share evidence copies with all team members
Immediately install new software on the suspect system
Maintaining a detailed log of who handles evidence and what is done ensures legal admissibility. Installing software, widespread sharing, or deleting logs compromises the chain of custody.
In a degraded communications environment, which fallback method best supports mission assurance?
Bluetooth mesh network
Standard VoIP telephony
Unsecured public Wi-Fi
Satellite communication link
Satellite links provide reliable, long-range communication when terrestrial networks fail. VoIP, public Wi-Fi, and Bluetooth are less dependable or secure under degraded conditions.
An intrusion detection system logs a flood of TCP SYN packets from one IP. What is the most likely interpretation?
A standard port scan
A SYN flood denial-of-service attack
An SSH brute-force attempt
A successful TCP three-way handshake
A high volume of SYN packets without corresponding ACKs typically indicates a SYN flood DoS attack. Port scans, completed handshakes, or SSH brute force have different traffic patterns.
Which network design uses VLAN segmentation and strict inter-VLAN routing controls to isolate sensitive systems?
Peer-to-peer VPN mesh
Flat network topology
Network segmentation with access control lists (ACLs)
Single VLAN for all departments
Segmenting networks into VLANs and enforcing ACLs on routing points isolates sensitive assets. Flat topologies, single-VLAN designs, and peer-to-peer meshes lack granular isolation.
