This sequence represents a successful attack by W32.IRCBot-TO. As reference, there is another sequence of transmitted packets (SEQ 2) obtained from the work of Gu. Host 9x.4x.53.209 did not succeed in its attack because it had its access denied by the honeypot.

The first number in each line is the transmitted packet number, and the arrows represent its direction. In the following, there is the sequence of packets transmitted by an attacker (SEQ 1), whose IP was 9x.4x.53.209 (georeferenced to Ireland) towards the XP honeypot. This paper also discusses the importance of network forensics and Chain of Custody procedures to conduct investigations and shows the effectiveness of the mentioned techniques in evaluating different attacks in networks. The data collected and analyzed is then used to generate statistics of used usernames and passwords, IP and services distribution, among other elements. Obtained results demonstrate the behavior of automated attacks (such as worms and bots) and non-automated attacks (brute-force conducted with different tools). In this perspective, this work could identify and map the content and behavior of attacks such as the Mirai botnet and brute-force attacks targeting various different network services. The contributions of this paper rely on the association of Deep Packet Inspection with forensics analysis to evaluate different attacks towards a Honeynet operating in a network laboratory at the University of Brasilia. Although being efficient, this technique still faces big challenges. As cyber attacks may occur on any layer of the TCP/IP networking model, Deep Packet Inspection is an effective way to reveal suspicious content in the headers or the payloads in any packet processing layer, excepting of course situations where the payload is encrypted. This paper addresses the use of a forensic approach with Deep Packet Inspection to detect anomalies in the network traffic. Strong security measures, forensic tools, and investigators contribute together to detect and mitigate those attacks, reducing the damages and enabling reestablishing the network to its normal operation, thus increasing the cybersecurity of the networked environment. Any network connected to the Internet is subject to cyber attacks.
