Summary:
Requests a zone transfer (AXFR)from a DNS server. The script sends an AXFR query to a DNS server. The domain to query is determined by examining the name given on the command line, the DNS server's hostname, or it can be specified with the dns-zone-transfer.domain' script argument. If the query is successful all domains and domain types are returned along with common type specific data (SOA/MX/NS/PTR/A). This script can run at different phases of an Nmap scan: * Script Pre-scanning: in this phase the script will run before any Nmap scan and use the defined DNS server in the arguments. The script arguments in this phase are:'dns-zone-transfer.server' the DNS server to use, can be a hostname or an IP address and must be specified. The 'dns-zone-transfer.port' argument is optional and can be used to specify the DNS server port. * Script scanning: in this phase the script will run after the other Nmap phases and against an Nmap discovered DNS server. If we don't have the 'true' hostname for the DNS server we cannot determine a likely zone to perform the transfer on. SYNTAX: dns-zone-transfer.server: DNS server. If set, this argument will enable the script for the 'Script Pre-scanning phase'. dns-zone-transfer.addall: If specified, adds all IP addresses including private ones onto Nmap scanning queue when the script argument 'newtargets' is given. The default behavior is to skip private IPs (non-routable). dns-zone-transfer.port: DNS server port, this argument concerns the 'Script Pre-scanning phase' and it's optional, the default value is '53'. dns-zone-transfer.domain: Domain to transfer.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
