Ann would like to perform a reliable scan against a remote target. She is not concerned about being stealth at this point.
Which of the following type of scans would be the most accurate and reliable option?
A UDP scan
A TCP Connect scan
A FIN scan
Explanation: A TCP Connect scan, named after the Unix connect() system call is the most accurate scanning method. If a port is open the operating system completes the TCP three- way handshake, and the port scanner immediately closes the connection. Otherwise an error code is returned.
Example of a three-way handshake followed by a reset:
[192.168.0.8][192.168.0.10]TCP: D=80 S=49389 SYN SEQ=3362197786 LEN=0 WIN=5840
[192.168.0.10] [192.168.0.8] TCP: D=49389 S=80 SYN ACK=3362197787 SEQ=58695210 LEN=0 WIN=65535
[192.168.0.8][192.168.0.10]TCP: D=80 S=49389 ACK=58695211 WINlt;lt;2=5840 [192.168.0.8][192.168.0.10]TCP: D=80 S=49389 RST ACK=58695211 WINlt;lt;2=5840

Harold is the senior security analyst for a small state agency in New York. He has no other security professionals that work under him, so he has to do all the security-related tasks for the agency. Coming from a computer hardware background, Harold does not have a lot of experience with security methodologies and technologies, but he was the only one who applied for the position. Harold is currently trying to run a Sniffer on the agency#39;s network to get an idea of what kind of traffic is being passed around, but the program he is using does not seem to be capturing anything. He pours through the Sniffer#39;s manual, but cannot find anything that directly relates to his problem. Harold decides to ask the network administrator if he has any thoughts on the problem. Harold is told that the Sniffer was not working because the agency#39;s network is a switched network, which cannot be sniffed by some programs without some tweaking. What technique could Harold use to sniff his agency#39;s switched network?
ARP spoof the default gateway
Conduct MiTM against the switch
Launch smurf attack against the switch
Flood the switch with ICMP packets

Which of the following commands runs snort in packet logger mode?
./snort -dev -h ./log
./snort -dev -l ./log
./snort -dev -o ./log

Explanation: Note: If you want to store the packages in binary mode for later analysis use
./snort -l ./log -b

Which address translation scheme would allow a single public IP address to always correspond to a single machine on an internal network, allowing quot;server publishingquot;?
Overloading Port Address Translation
Dynamic Port Address Translation
Dynamic Network Address Translation
Static Network Address Translation
Explanation: Mapping an unregistered IP address to a registered IP address on a one-to- one basis. Particularly useful when a device needs to be accessible from outside the network.

Neil notices that a single address is generating traffic from its port 500 to port 500 of several other machines on the network. This scan is eating up most of the network bandwidth and Neil is concerned. As a security professional, what would you infer from this scan?
It is a network fault and the originating machine is in a network loop
It is a worm that is malfunctioning or hardcoded to scan on port 500
The attacker is trying to detect machines on the network which have SSL enabled
The attacker is trying to determine the type of VPN implementation and checking for IPSec
Explanation: Port 500 is used by IKE (Internet Key Exchange). This is typically used for IPSEC-based VPN software, such as Freeswan, PGPnet, and various vendors of in-a-box VPN solutions such as Cisco. IKE is used to set up the session keys. The actual session is usually sent with ESP (Encapsulated Security Payload) packets, IP protocol 50 (but some in-a-box VPN#39;s such as Cisco are capable of negotiating to send the encrypted tunnel over a UDP channel, which is useful for use across firewalls that block IP protocols other than TCP or UDP).
