Universal Plug and Play (UPnP) works by discovery and advertisements so that the network is aware of what services and devices are available. SSDP enables clients to discover network services with little or no static configuration. Lisa Bock dives into SSDP, which can be used for passive discovery of network devices.

This course investigates the scanning tools and techniques used to obtain information from a target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps. Lisa Bock discusses how hackers can identify live systems via protocols, blueprint a network, and perform a vulnerability scan to find weaknesses. She also introduces some of the tools and techniques that hackers use to counter detection via evasion, concealment, and spoofing. In addition, learn how to reduce the threat of tunneling, a method hackers use to circumvent network security.
Note: Our Ethical Hacking series maps to the 18 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50). This course maps to the 03 Scanning Networks domain.
