Q412. Stephanie, a security analyst, has just returned from a Black Hat conference in Las Vegas where she learned of many powerful tools used by hackers and security professionals alike. Stephanie is primarily worried about her Windows network because of all the legacy computers and servers that she must use, due to lack of funding.
Stephanie wrote down many of the tools she learned of in her notes and was particularly interested in one tool that could scan her network for vulnerabilities and return reports on her network's weak spots called SAINT. She remembered from her notes that SAINT is very flexible and can accomplish a number of tasks. Stephanie asks her supervisor, the CIO, if she can download and run SAINT on the network. Her boss said to not bother with it since it will not work for her at all.
Why did Stephanie's boss say that SAINT would not work?
A. SAINT only works on Macintosh-based machines
B. SAINT is too expensive and is not cost effective
C. SAINT is too network bandwidth intensive
D. SAINT only works on LINUX and UNIX machines
Answer: D
Explanation: Works with Unix/Linux/BSD and MacOS X http://www.saintcorporation.com/
Q413. An Employee wants to bypass detection by a network-based IDS application and does not want to attack the system containing the IDS application. Which of the following strategies can the employee use to evade detection by the network based IDS application?
A. Create a ping flood
B. Create a SYN flood
C. Create a covert network tunnel
D. Create multiple false positives
Answer: C
Explanation: HTTP Tunneling is a technique by which communications performed using various network protocols are encapsulated using the HTTP protocol, the network protocols in question usually belonging to the TCP/IP family of protocols. The HTTP protocol therefore acts as a wrapper for a covert channel that the network protocol being tunneled uses to communicate. The HTTP stream with its covert channel is termed a HTTP Tunnel. Very few firewalls blocks outgoing HTTP traffic.
Q414. Exhibit
Joe Hacker runs the hping2 hacking tool to predict the target host’s sequence numbers in one of the hacking session.
What does the first and second column mean? Select two.
A. The first column reports the sequence number
B. The second column reports the difference between the current and last sequence number
C. The second column reports the next sequence number
D. The first column reports the difference between current and last sequence number
Answer: AB
Q415. Which of the following commands runs snort in packet logger mode?
A. ./snort -dev -h ./log
B. ./snort -dev -l ./log
C. ./snort -dev -o ./log
D. ./snort -dev -p ./log
Answer: B
Explanation: Note: If you want to store the packages in binary mode for later analysis use ./snort -l ./log -b
Q416. SSL has been as the solution to a lot of common security problems. Administrator will often time make use of SSL to encrypt communications from points A to Point B. Why do you think this could be a bad idea if there is an Intrusion Detection System deployed to monitor the traffic between Point A to Point B?
A. SSL is redundant if you already have IDS’s in place
B. SSL will trigger rules at regular interval and force the administrator to turn them off
C. SSL will make the content of the packet and Intrusion Detection System are blinded
D. SSL will slow down the IDS while it is breaking the encryption to see the packet content
Answer: C
Explanation: An IDS will not be able to evaluate the content in the packets if it is encrypted.
Q417. Switches maintain a CAM Table that maps individual MAC addresses on the network to physical ports on the switch.
In MAC flooding attack, a switch is fed with many Ethernet frames, each containing different source MAC addresses, by the attacker. Switches have a limited memory for mapping various MAC addresses to physical ports. What happens when the CAM table becomes full?
A. Switch then acts as hub by broadcasting packets to all machines on the network
B. The CAM overflow table will cause the switch to crash causing Denial of Service
C. The switch replaces outgoing frame switch factory default MAC address of FF:FF:FF:FF:FF:FF
D. Every packet is dropped and the switch sends out SNMP alerts to the IDS port
Answer: A
Q418. Study the snort rule given below:
From the options below, choose the exploit against which this rule applies.
A. WebDav
B. SQL Slammer
C. MS Blaster
D. MyDoom
Answer: C
Explanation: MS Blaster scans the Internet for computers that are vulnerable to its attack. Once found, it tries to enter the system through the port 135 to create a buffer overflow. TCP ports 139 and 445 may also provide attack vectors.
Q419. Which of the following is one of the key features found in a worm but not seen in a virus?
A. The payload is very small, usually below 800 bytes.
B. It is self replicating without need for user intervention.
C. It does not have the ability to propagate on its own.
D. All of them cannot be detected by virus scanners.
Answer: B
Explanation: A worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided.

1. mkdir -p /etc/X11/applnk/Internet/.etc
2. mkdir -p /etc/X11/applnk/Internet/.etcpasswd
3. touch -acmr /etc/passwd /etc/X11/applnk/Internet/.etcpasswd
4. touch -acmr /etc /etc/X11/applnk/Internet/.etc
5. passwd nobody -d
