[Paper] Going a Step Beyond the Black and White Lists for URL Accesses in the Enterprise by means of Categorical Classifiers

Our work titled Going a Step Beyond the Black and White Lists for URL Accesses in the Enterprise by means of Categorical Classifiers, as part of the researh under the MUSES project, has been presented today at the ECTA 2014 conference.

Abstract:

Corporate systems can be secured using an enormous quantity of methods, and the implementation of Black or White lists is among them.
With these lists it is possible to restrict (or to allow) the users the execution of applications or the access to certain URLs, among others. This paper is focused on the latter option. It describes the whole processing of a set of data composed by URL sessions performed by the employees of a company; from the preprocessing stage, including labelling and data balancing processes, to the application of several classification algorithms. The aim is to define a method for automatically make a decision of allowing or denying future URL requests, considering a set of corporate security policies.
Thus, this work goes a step beyond the usual black and white lists, since they can only control those URLs that are specifically included in them, but not by making decisions based in similarity (through classification techniques), or even in other variables of the session, as it is proposed here.
The results show a set of classification methods which get very good classification percentages (95-97%), and which infer some useful rules based in additional features (rather that just the URL string) related to the user’s access. This led us to consider that this kind of tool would be very useful tool for an enterprise.

Out of CPU cycles and in need to do science? No problem!

After the bad experience of spending money in clusters and grids and then spending more time doing maintenance, hack-proofing and installing stuff than science, maybe it is the time to rethink how massive distributed evolutionary computation should be done. Nowadays there are lots of free or use-based resources that can be tapped for doing volunteer-based evolutionary algorithms. That is way my last keynote and tutorial have dealt with that: the IDC Keynote, Low or No Cost Evolutionary computation, which you can access here in Heroku, puts the money where its mouth is: talking and doing volunteer-based evolutionary computing at the same time. The PPSN tutorial, Low or no cost distributed evolutionary computation, touched on the same topic, only longer and with more enphasis on tools.
So finally it is just a matter of a little Javascript and using free cloud resources and you can have your very own massive distributed experiment. Whose results will be published soon enough.

CFP for EvoGAMES 2015

Are you into games and computational intelligence? Submit your paper to this conference track, deadline in a month.

The EvoGAMES blog

The deadline for EvoGAMES 2015 is approaching: 15 November.

Please, prepare ASAP your (excellent :D) contribution to the edition of this year, for two main reasons: first Evo* will be held in the beautiful city of Copenhagen (Denmark); and second, we are working hard to join a special issue in a very good JCR journal.

Thus, the selected papers will be proposed to be included in it, after an extension/improvement phase, of course. ;)

The main topics are (not limited to):

  • Computational Intelligence in video games
  • Intelligent avatars and new forms of player interaction
  • Player experience measurement and optimization
  • Procedural content generation
  • Human-like artificial adversaries and emotion modelling
  • Authentic movement, believable multi-agent control
  • Experimental methods for gameplay evaluation
  • Evolutionary testing and debugging of games
  • Adaptive and interactive narrative
  • Games related to social, economic, and financial simulations
  • Adaptive educational, serious and/or social games
  • General game intelligence (e.g. general purposeā€¦
