With the help of NESSUS, an attacker can generate the attack surface. Following this, s/he can o consult the National Database of Vulnerabilities (NVD) as the next best step to find which vulnerabilities are there in the attacked network O check US-CERT advisories to figure our latest news about the viruses to find new attack methods O repeat the reconnaissance with NMAP that does not list vulnerabilities to make sure the open ports are confirmed open look for exploits some places like the exploit-db or create one themselves QUESTION 6 An organization deploys a demilitarized zone (DMZ) in order to O keep attackers out of their organization's networks O as intrusion prevention system (IPS) as a way to attract attacks and collect information about them as a firewall between a honeypot and a production network QUESTION 7
