    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.
