DNS column is blank for my MAP result. Any recommendations on what needs to be checked?
okay, it may need more investigation but could you confirm what Option profile did you use and the host OS of the targets?
We're using 'DiscoveryAndMapping' option profile with the following setting. Most of the OS of targets are windows 7, vista.. Basically, my objective is to set a scheduled weekly map and scan for the 'workstation/computer' VLAN. My target for the scan is not whole IP range but specific samples only. But how am I supposed to do that if IPs are dynamic.Will scan by hostname a good approach OR tracked via DNS/Netbios?
Scanned TCP and UDP ports: FULL
Scan dead hosts: OFF
Load Balancer detection: Off
Perform 3-way handshake: Off
Vulnerability detection: Custom (SSH version 1, QID 38304)
Include basic host checks: yes
Password brute forcing: Disabled
Overall performance: Normal
Packet (Burst) delay: Medium
Windows share enumeration: Disabled
Basic info gathering: All hosts
TCP and UDP ports: Standard scan
Live host sweep: ON
Authenticated scans: OFF
TCP and UDP: Standard scan
Ignore FW generated TCP: OFF
Ignore all TCP RST packets: OFF
Do not send TCP ACK or SYN-ACK packets during host discovery: Off
Start tracking by NetBIOS hostname or use an Asset tag if there is something common on these IP's when you scan.
The Option Profile for the map looks good to me. Can you check if tcp/udp 53 is allowed between scanner and the target.
