A little while ago we announced the Infosec Glossary at In this feature, we update the layout and add Suggest Edit and Suggest Addition features! The new layout has a much more compact look so you don't have to scroll the page so much.


Overview -

  • Mostly unchanged except for the link to Suggest an Addition described below.

List of Terms -

  • This is a much more responsive, compact list and still has the search box to limit list to matching terms.
  • Mouse over a term in the list to view definition and options.
  • "suggest edit" option displays definition box for you to change then optionally enter a name and click the check button to submit.

Suggest an Addition -

  • Enter a Term not in the list above
  • Enter a definition for the term
  • Optionally enter your name
  • Click the check button to submit

A reader posted that they are observing strange TCP 443 behavior that looks like a fast flux [1] style pattern. They have a large snort sensor install base. Is anyone else seeing behavior like this? If so.... Got packets?

If you are seeing this behavior and are allowed please report it!
