Study Notes
Network Scanning
- Network scanning involves identifying hosts, ports, and services in a network to gather information about the target organization.
- Objectives of network scanning include:
- Identifying live hosts, IP addresses, and open ports of live hosts.
- Discovering services running on hosts.
- Discovering vulnerabilities in live hosts.
Scanning Techniques
- Ping scan: involves sending ICMP ECHO requests to a host to determine if it is live and if ICMP is passing through a firewall.
- Ping scan output can be obtained using tools like Nmap.
Tools for Ping Scanning
- Colasoft Ping Tool: a network scanning tool for Windows.
- Advanced IP Scanner: a free tool for scanning IP addresses and ports.
- Visual Ping Tester - Standard: a tool for testing ping responses.
- Ping Sweep: a tool for pinging a range of IP addresses.
- Ping Scanner Pro: a tool for scanning IP addresses and ports.
- OpUtils: a network management tool with ping scanning capabilities.
- Ping Monitor: a tool for monitoring ping responses.
- Ping Info View: a tool for viewing ping responses.
- Pinkie: a tool for pinging IP addresses.
Overview of Network Scanning Process
- Sends packets to the network to gather information.
- Gets network information about hosts, ports, and services.
Check for Live Systems and Open Ports
- Checking for live systems involves scanning for hosts that respond to ICMP ECHO requests.
- Checking for open ports involves scanning for ports that respond to connection attempts.
Scanning Beyond IDS and Banner Grabbing
- Scanning beyond IDS (Intrusion Detection Systems) involves evading detection by IDS.
- Banner grabbing involves collecting information about services running on hosts.
Scan for Vulnerability and Draw Network Diagrams
- Scanning for vulnerabilities involves identifying weaknesses in hosts and services.
- Drawing network diagrams involves creating visual representations of the network infrastructure.
Prepare Proxies and Scanning Pen Testing
- Preparing proxies involves setting up anonymizers for attack.
- Scanning pen testing involves simulating attacks on the network to test defenses.
This quiz covers network security scanning techniques, including scanning for open ports, vulnerability scanning, and network diagramming. It also touches on the use of proxies and network troubleshooting tools.
