CertNexus CFR-410 (CyberSec First Responder) Certification Exam is a globally recognized certification that validates the skills and knowledge of cybersecurity professionals in detecting, analyzing, and responding to security incidents. CyberSec First Responder certification is designed to equip candidates with the necessary skills to effectively manage and mitigate cyber threats that businesses face in today’s digital landscape.

Q83. An attacker intercepts a hash and compares it to pre-computed hashes to crack a password. Which of the following methods has been used?

Password sniffing

Brute force attack

Rainbow tables

Dictionary attack

Q84. During an incident, the following actions have been taken:
-Executing the malware in a sandbox environment
-Reverse engineering the malware
-Conducting a behavior analysis
Based on the steps presented, which of the following incident handling processes has been taken?

Containment

Eradication

Recovery

Identification

The “Containment, eradication and recovery” phase is the period in which incident response team tries to contain the incident and, if necessary, recover from it (restore any affected resources, data and/or processes).

Q85. How does encryption work to protect information on remote workers’ computers?

It is difficult to set up, so an unskilled attacker won’t be able to figure it out.

Without the proper key, an attacker won’t be able to unscramble the encrypted information.

Using encryption requires advanced training in mathematics, which is beyond the capabilities of most attackers.

Information can be encrypted but it can never be decrypted leaving an attacker unable to read the information

Encryption works by converting data into an unreadable format using a cryptographic algorithm and a key.
The information can only be decrypted and returned to its original, readable form by someone who possesses the correct decryption key. This ensures that even if an attacker gains access to the encrypted data, they won’t be able to make sense of it without the proper key.

Q86. Where are log entries written for auditd in Linux?

/etc/audit/audit.rules

/var/log/audit/messages

/var/log/audit/audit.log

/var/log/audit.log

/etc/audit/audit.conf

In Linux, log entries for auditd (the audit daemon) are written to /var/log/audit/audit.log. This file contains detailed information about system activity, including security-related events, which is essential for auditing and monitoring purposes.

Q87. Which of the following should normally be blocked through a firewall?

SNMP

SMTP

NTP

POP3

SNMP (Simple Network Management Protocol) is typically used for network management and monitoring but can be a security risk if not properly secured. SNMP can provide attackers with valuable information about network devices if exposed to the internet, which is why it is generally blocked through firewalls unless absolutely necessary and securely configured.

Q88. A security administrator needs to review events from different systems located worldwide. Which of the following is MOST important to ensure that logs can be effectively correlated?

Logs should be synchronized to their local time zone.

Logs should be synchronized to a common, predefined time source.

Logs should contain the username of the user performing the action.

Logs should include the physical location of the action performed.

Section: (none)
Explanation

Q89. A Linux system administrator found suspicious activity on host IP 192.168.10.121. This host is also establishing a connection to IP 88.143.12.123. Which of the following commands should the administrator use to capture only the traffic between the two hosts?

# tcpdump -i eth0 host 88.143.12.123

# tcpdump -i eth0 dst 88.143.12.123

# tcpdump -i eth0 host 192.168.10.121

# tcpdump -i eth0 src 88.143.12.123

Q90. Which of the following technologies would reduce the risk of a successful SQL injection attack?

Reverse proxy

Web application firewall

Stateful firewall

Web content filtering

Q91. Which of the following tools can help to detect suspicious or unauthorized changes to critical system configuration files?

Tripwire

Logstash

Nessus

Netcat

Ifconfig

Tripwire is a file integrity monitoring tool that helps detect unauthorized or suspicious changes to critical system configuration files. It compares the current state of files to known baselines and alerts administrators if any unauthorized changes are made.

Q92. A system administrator has been tasked with developing highly detailed instructions for patching managed assets using the corporate patch management solution. These instructions are an example of which of the following?

Process

Procedure

Standard

Policy

A procedure is a set of detailed, step-by-step instructions that guide users through specific tasks. In this case, the system administrator is creating instructions for patching managed assets, which qualifies as a procedure.
It outlines the exact steps to be followed to accomplish a particular task.

Q93. According to SANS, when should an incident retrospective be performed?

After law enforcement has identified the perpetrators of the attack.

Within six months following the end of the incident.

No later than two weeks from the end of the incident.

Immediately concluding eradication of the root cause

According to SANS, an incident retrospective should be performed no later than two weeks from the end of the incident. This allows the team to review the response, identify lessons learned, and improve future incident handling while the details are still fresh.

Q94. Which of the following are common areas of vulnerabilities in a network switch? (Choose two.)

Default port state

Default credentials

Default protocols

Default encryption

Default IP address
