On a Thursday afternoon, a network intrusion detection sensor records vulnerability scanning activity directed at internal hosts that is being generated by an internal IP address. Because the intrusion detection analyst is unaware of any authorized, scheduled vulnerability scanning activity, she reports the activity to the incident response team. When the team begins the analysis, it discovers that the activity has stopped and that there is no longer a host using the IP address. The following are additional questions for this scenario: 1. What data sources might contain information regarding the identity of the vulnerability scanning host? 2. How would the team identify who had been performing the vulnerability scans? 3. How would the handling of this incident differ if the vulnerability scanning were directed at the organization's most critical hosts? 4. How would the handling of this incident differ if the vulnerability scanning were directed at external hosts? 5. How would the handling of this incident differ if the internal IP address was associated with the organization's wireless guest network? 6. How would the handling of this incident differ if the physical security staff discovered that someone had broken into the facility half an hour before the vulnerability scanning occurred?

Security personnel generally have two goals when using a honeypot. A honeypot can deflect or redirect threat actors' attention away from legitimate servers by encouraging them to spend their time and energy on the decoy server, distracting their attention from the data on the actual server. A honeypot can also trick threat actors into revealing their attack techniques. Once these techniques are discovered, it can then be determined if actual production systems could thwart such an attack. However, honeypots can introduce risk. A honeypot, once attacked and compromised, could be used as a launching pad to attack and infiltrate other systems, either those of the organization itself or another organization. Although honeypots should be designed to "capture" the threat actor, a misconfiguration could inadvertently give an attacker an actual platform to attack other systems. If a threat actor were able to do this, would the organization that set up the honeypot then be liable? How would you define "without authorization"? The Computer Fraud and Abuse Act (CFAA) imposes both criminal and civil liability on someone who intentionally accesses a computer "without authorization" or "exceeds authorized access" to obtain information from the computer. Some businesses argue that "without authorization" also applies to security researchers who are probing programs or apps for vulnerabilities. Often these businesses do not want security researchers looking into their security (or lack of it). One such company filed a brief in a court case stating that "necessary research and testing can be performed by authorized parties... and shows how unauthorized research and public dissemination of unvalidated or theoretical security vulnerabilities can actually cause harmful effects." Should "without authorization" be used to prohibit security researchers who want to pinpoint vulnerabilities? Or can it still allow for security researchers to find unknown vulnerabilities in software—even if they have not been asked to?
