Concluding Thoughts
This chapter provides an introduction to operational aspects of psad as it detects and reports port scans that are levied against the iptablesfw system with Nmap. Email reports are the primary psad alerting mechanism, but syslog alerts are also provided by psad. In the next chapter we will explore more advanced psad topics, such as the detection of traffic that matches Snort rules via iptables log messages.
