SNMP Versions
What does SNMP stand for?
Simple Network Management Protocol
What is a network baseline?
The averaging performance rate of a network.
What does QoS stand for?
Quality of Service
What is the first step in the incident response process?
Preparation.
What is a Blackout?
Complete power loss.
Which SNMP version introduced encryption?
SNMP v3
Why is establishing a baseline important?
So you know the line between normal and abnormal.
Name one method used to implement QoS.
DiffServ
What is the purpose of the containment step?
What is a Brownout?
Momentary decrease in voltage.
Describe a key difference between SNMP v1 and v3.
SNMP uses encryption and has authentication and verification.
How often should a network baseline be reviewed?
Monthly.
Why is QoS important for VoIP applications?
Voice is delay sensitive.
Describe the review step.
Reflecting on the causes of the issues and how to better prepare for it in the future.
What is a PDU. (Power not packet)
The source of power for networking devices.
What are the security features of SNMP v3?
Authentication and verification.
What tools can be used to establish a network baseline?
Network monitoring tools, flow control and performance testing tools.
Explain the difference between traffic shaping and traffic policing.
Shaping tries to buffer and smooth out data while prioritizing some data. Policing drops packets to average the cable speed's limit.
Why is the preparation step important?
Without preparation you will have no mitigation in the event there is an attack.
What is a UPS.
A battery-operated power source directly
attached to devices and to a power supply.
What does SNMP do?
Collects and manages data produced by networking devices.
How can establishing a baseline aid a network?
When a threat or problem is identity, the mangers will be able to detect as it will causes problems that are not found on the baseline.
What type of data is often prioritized the most?
Voice and Video.
How often should you rotate though the preparation step.
You should be constantly preparing and adding in migrations to prepare for an attack that was not though of before.
What is one cause for a power surge?
Lightning strikes or solar flares, or electrical
problems.
