I'm trying to search twitter for evidence of near-realtime alerts or updates regarding security issues.

What hashtags are common or popular in the IT Security world?

#infosec and #security are the two main hashtags I'm aware of.

Depending on what you're interested in there are other less popular hashtags. For example:

  • #websecurity
  • #privacy
  • #cybercrime
  • #cyberwar
  • #hacker and #hackers
  • #cybersecurity
  • #malware
  • #spam

There's also the option to use multiple hashtags in your search. If, for example, you are interested in Android security, you can search for "#android AND #security".

It all depends on the type of content your are posting. In most cases you will need more than one #Tag for your tweet to make the right sense and ranking.

  • #InfoSec (preferred abbreviation)
  • #InformationSecurity (if you have some characters left in your tweet)
  • #Risk (Topics also relating to risk management)
  • #Privacy
  • #Malware
  • #Virus
  • #Spam
  • #BYOD
  • #DataTheft / #DataLoss / #DataLeak
  • #CISO / #CSO (If your tweet needs to draw attention of senior management audience)
  • #Breach (If you are referring to a compromise)
  • #Hack / #Hacker (You may use these along with #Breach)
  • #MobileSec / #MobileSecurity

I'm an information security professional & often post on Twitter.

You can also try the following:

  • #mobilemalware
  • #mobilesecurity
  • #informationsecurity

I would personally go with #infosec instead, much shorter (stupid twitter character limit) and everyone in the industry knows it. – Luc Aug 12 '14 at 13:20
Well, this is the most advisable method no matter what. However, the others are also useful for specifications and not everyone (unfortunately) is aware of the #infosec hashtag. – brbtsl Aug 12 '14 at 13:25
