Lisa Bock reviews some approaches that administrators can take when scanning an IPv6 network. Understand the three ways in IPv6 to configure a host with an IP address: Manual, Stateless Address AutoConfiguration (SLAAC) and DHCPv6, which are generally predictable patterns. Discover guidelines to foil the predictable nature of IPv6 configuration and reduce the threat of exposure.
- [Voiceover] IP version Six…has a significantly larger address base…than IP version Four.…In 2016, the share of IP version Six traffic…is at nearly 10% and this growth will continue.…When comparing IP version Four to IP version Six,…the potential of a huge address range exist.…With IP version Six, a standard subnet size for LAN…is slash 64.…
The slash 64 is required in order…for Stateless Address Autoconfiguration or SLAAC to work.…With 64-bit, a subnet has a potential…for up to 18.4 quintillion host addresses,…an insanely large number…that would prevent any type of scanning.…However, scanning and locating devices…is possible in IP version Six networks…by using tools that predict patterns.…
In IP version Six,…there are three ways to configure a host with an IP address:…Manual, Stateless Address Autoconfiguration…and DHCP version six.…Manually configured addresses in IP version Six…are generally assigned a pattern.…Although they can be assigned randomly,…the network administrator…will most likely assign the addresses,…
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.
