Cyber Defense: How to Protect Against Hackers – Recon Defense, Part One

As the old saying goes, “One man’s junk is another man’s treasure”. One favorite technique of hackers is to “Dumpster Dive”. Yes, this literally means to dig through your trash.

Corporate Network ID tags sometimes have the network name and internal IP Address listed, this information could also be used. Some people even tape passwords to machines and monitors.
