Discover the many network mapping tools available for device and topology discovery. Lisa Bock offers some examples that are paid or free, and use multiple discovery methods such as SNMP, ICMP, and CDP so you can visualize devices on your network in order to detect operating systems, hostnames, and open ports.
- [Voiceover] The network administrator…has many network mapping tools available,…which should be explored.…Some are paid versions, some are free,…and some allow a trial download.…In some cases, they will encourage you…to sign up for a free demo.…Let's take a look at some of them…that are available out there.…I'm at this webpage here,…where we can see OpManager.…This can be downloaded, you can try it,…and it gives a nice digital dashboard,…as you see in this visual…right down at the bottom of this page.…
SolarWinds Network Topology Mapper,…you can see here, gives us a nice dashboard…and visualization of your network.…I downloaded and installed a free trial.…I've opened it up as I had done a quick scan of the network,…and, as you see, it shows a simple visualization…of the network and the devices that are included.…Again, this is a free trial…just to give you an understanding…of some of the components and some of the features.…
The Dude is also a network monitor application…and it takes a look at all the devices…within your specified subnet…
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.
