Not long ago, information systems security was closely associated with
passive protection, always assuming a purely defensive
stance. Nowadays, this approach is changing. Reactive measures are
helping to improve systems security, with the use of hosts prepare to
be compromised (honeypots) providing information about the techniques
used by the attackers, from the attackers themselves. Based on this
new approach to information systems security, this paper shows a
system developed to stealthily monitor all the attackers' activities
in the honeypots and transfer these informations to monitoring
stations.
