CND Practice Question: Network Security Controls Protocols And Devices
A security engineer needs to configure secure log management and transmission from edge firewalls and switches to a centralized SIEM server. Which TWO protocols or features ensure that log data is transmitted securely and integrally across the network? (Choose two)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Encrypted log forwarding via HTTPS REST APIs to the SIEM collector
Standard Syslog (UDP 514) transmits logs in cleartext. Secure transmission requires Syslog over TLS or encrypted forwarding mechanisms like SECURE SNMP/SFTP/HTTPS log shipping.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Unencrypted UDP Syslog (Port 514)
Why it's wrong here
UDP Syslog sends log messages in cleartext, vulnerable to sniffing and tampering.
- ✓
Encrypted log forwarding via HTTPS REST APIs to the SIEM collector
Why this is correct
Using encrypted HTTPS APIs ensures confidentiality and integrity of log transmissions.
- ✓
Syslog over TLS (TCP Port 6514)
Why this is correct
Syslog over TLS encrypts log data in transit between network devices and the SIEM server.
- ✗
Unauthenticated TFTP log backup transfers
Why it's wrong here
TFTP lacks authentication and encryption entirely.
- ✗
SNMPv1 trap forwarding
Why it's wrong here
SNMPv1 traps use unencrypted community strings and lack security.
