The following is part of a log file taken from the machine on the network with the IP address of 192.168.0.110: What type of activity has been logged?

A teardrop attack sends fragmented IP packets with overlapping offset values to crash the target's TCP/IP stack; this would not produce the sequential port-probe log pattern described.

A denial of service attack targeting 192.168.0.105 would appear in the logs of that machine, not on 192.168.0.110, and DoS traffic patterns differ from port scan signatures.

A port scan generates log entries showing probe attempts against many different ports on a destination IP address in a short time frame, which is exactly what would appear on the machine at 192.168.0.110 receiving those probes. The log is captured on 192.168.0.110, so that host is the target - its logs record inbound connection attempts originating from an external source.

A port scan targeting 192.168.0.105 would be logged by 192.168.0.105 as the recipient, not by 192.168.0.110; 192.168.0.110 could only log traffic directed at itself.
