Internet Security Services

Impakt nv/sa provides a range of services for companies and organizations who are taking Internet security seriously. Through the proliferation of users on the Internet many organizations with a Internet host are concerned about attacks from the outside. Standard configuration of UNIX systems often allows hackers access to vital information through simple means, from stealing passwords through the installation of Trojan horses up to sophisticated techniques such as address spoofing. Did you know that studies have shown that a freely available program called cracker has 25% chance of finding the password of a random user? If you have 16 users on your system that brings the probability to 99% that a hacker will find the password of one user. Many UNIX systems are configured in such a way that the /etc/passwd file can be downloaded with use of tftp.

Impakt nv/sa provides several products and services ranging from one-time consultancy to turnkey firewall solutions. These services include:
