Software Tools

Question 1

Protocol analyszer (packet capture)

Answer 1

Captures and anylzes net packets flowing over the net, captures raw packets allowing fire header and payload inspection
- uses:
Identify congestion, latency, packet loss
- net performance monitoring- analyze traffic patterns
Looks at individual packets while net flow analyzers look at summarizes flow of data

Question 2

WiFi analyzer

Answer 2

Scan for WiFi networks in the vicinity and analyzes them for signal strength, channels used, and tell u best channel optimization
-used for:
-checking signal strength, channels interference form other devices using same frequencies and channel optimization

Question 3

Spectrum analyzer

Answer 3

Used to measure signal rf signal characteristics like power level, phase noise and harmonics
-used for:
-freq analysis identify presence of signals and their strength
- interference detection- analyzes interference from other devices
-rf performance testing- evaluates signal quality

Question 4

Netflow analyzer

Answer 4

Monitoring tool that collects and analyzes network traffic data
Used for:
-traffic analysis ( src/des ip, port, protocol, packet counts)
- bandwidth monitoring
-security- comparing with baseline(used to take a baseline)
