During a network security incident, what is an immediate task during the “Identification” phase of incident response?
A) disconnecting the affected systems from the network
B) implementing additional security measures to prevent further incidents
C) analyzing logs and traffic patterns to understand the incident’s nature
D) notifying company management and affected shareholders about the incident
Analyzing logs and traffic patterns to understand the incident’s nature
During the “Identification” phase, analyzing logs and traffic patterns is crucial to understand the nature and scope of the incident.
An organization suspects an insider threat. What is a vital step during the “Identification” phase of incident response for this situation?
A) notifying law enforcement for immediate investigation
B) conducting a comprehensive audit of user access logs and privileges
C) disabling network connectivity to prevent further potential damage
D) implementing new security protocols to prevent similar incidents
Conducting a comprehensive audit of user access logs and privileges
During the “Identification” phase for an insider threat, conducting a comprehensive audit of user access logs and privileges is crucial to identify unusual or suspicious activities within the network.
A company is addressing a significant breach in their database systems. What is an essential action during the “Containment” phase of incident response in this situation?
A) isolating affected systems and preventing the incident from spreading
B) informing the media and public about the breach for transparency
C) conducting a detailed investigation to identify the root cause
D) enhancing the system’s security through new firewalls and protocols
Isolating affected systems and preventing the incident from spreading
During the “Containment” phase, isolating affected systems is crucial to prevent the spread of the incident to other parts of the network and limit the damage.
An organization experiences a malware outbreak across its network. What should be a priority during the “Eradication and Recovery” phase of incident response in this scenario?
A) disconnecting affected systems from network
B) investigating the source of the malware and tracing its propagation
C) restoring affected systems to a clean and secure state
D) enhancing employee awareness of cybersecurity best practices
Restoring affected systems to a clean and secure state
During the “Eradication and Recovery” phase, restoring affected systems to a clean and secure state is a priority to eliminate the malware and return systems to normal functionality.
A system outage occurred due to a cyber attack. What is a crucial action during the “Lessons Learned” phase of incident response in this case?
A) filing lawsuits against identified attackers for damages
B) documenting the incident details, responses, and areas for improvement
C) implementing immediate measures to counter future cyber attacks
D) publicly announcing the incident to rebuild customer trust and confidence
Documenting the incident details, responses, and areas for improvement
During the “Lessons Learned” phase, documenting incident details and responses, and identifying areas for improvement is crucial for future incident response improvement.
A network administrator wants to map the network topology and identify active hosts and their connections. Which tool would be most suitable for this purpose?
A) tracert/traceroute
B) nslookup/dig
C) Nmap
D) ipconfig/ifconfig
Nmap
nmap (Network Mapper) is a powerful tool used for network discovery and security auditing. It scans networks, identifies active hosts, their services, and can provide information about open ports, OS detection, etc. It’s commonly used for mapping network topology.
