With the increase of attacks on the Internet, a primary concern for organizations is how to protect their network. The objectives of a security team are 1) to prevent external attackers from launching successful attacks against organization computers that could become compromised, 2) to ensure that organization computers are not vulnerable (e.g., fully patched) so that in either case the organization...
There are currently no generally accepted metrics for information security issues. One reason is the lack of validation using empirical data. In this practical experience report, we investigate whether metrics obtained from security devices used to monitor network traffic can be employed as indicators of security incidents. If so, security experts can use this information to better define priorities...
This paper describes an empirical study to assess whether computer focused crimes are impacted by system configurations. The study relies on data collected during 30 days on a farm of target computers of various configurations (disk space, memory size, and bandwidth). In addition, some target computers included a warning sign. Following a brute force attack on SSH, attackers randomly access one of...
