Software Tools
Network Scanners Family of tools used to analyze networks Packet sniffers Intrusion detection system (IDS/IPS)software Port scanners
Packet sniffers Actually looks inside every packet on a network segment Give statistics on network utilization and packet traffic data as well as capture individual frames for analysis The basic purpose is to collect and analyze each individual packet that is captured on a specific network segment to determine if problems like bottlenecks, retransmissions, and security breaches are happening
Packet sniffers
Intrusion Detection & Prevention Software IDS Identifies, detects, and reports attempts of unauthorized access to the network as well as any suspicious activity IPS Can stop the attack by shutting down ports or dropping certain types of packets
Port scanners Software tool designed to search a host for open ports
Hardware Tools
Cable Testers Verify connection through the cable Determine if the cable is straight- through or crossover Identify problems such as grounding issues as well
Loopback Plug Diagnostic procedure in which a signal is transmitted and returned to the sending device after passing through all or a portion of a network or circuit Are made for both Ethernet an fiber applications
Wire-Map Testers Device that transmit signals through each wire in a copper twisted-pair cable to determine if it’s connected to the correct pin at the other end. Consists of a remote unit that you attach to the far end of a connection and a battery-operated, handheld main unit that displays the results
Multimeter Called volt/ohm meter (VOM) Multitasking electronics measuring instrument Measure voltage, current, and resistance
Toner Probe Simple copper cable tester that is simple to use and can be used to trace a wire in a wall Can identify a particular cable at any point between the two ends, and because the probe can detect the cable containing the tone signal through its sheath.
Punch-Down Tool Use to punch down the wire that terminated in wiring closets into some kind of insulation displacement connector (IDC)
Cable Stripper/Snips
