Postmodern Security

I confess: I covet and hoard security tools. But I’m also frugal and impatient, so often look for something free and/or quick. And yes, that frequently means using an online, hosted service. Before the security-purists get their panties in a wad, I’d like to offer this disclaimer: you may mock me for taking shortcuts, but it’s not always about having the best tool, but the one that gets the job done.

Here’s a list that I frequently update. You’ll notice that sometimes I have the same tool in more than one section, but this is because it has multiple functions. If you know of others and would like to contribute or if you think the tool is outdated or bad, please let me know and I’ll adjust the list accordingly.

Many thanks to @grecs for his additions and helping me to organize it. Also to Lenny Zeltzer, author of the REMnux malware analysis and reverse engineering distro, who I’ve borrowed shamelessly from. You’ll find many of these tools and others on his own lists, so I encourage you to check his posts on this topic as well.
