7QUESTION 7
Anonymizer sites access the Internet on your behalf, protecting your personal information from disclosure. An anonymizer protects all of your computer's identifying information while it surfs for you, enabling you to remain at least one step removed from the sites you visit.
You can visit Web sites without allowing anyone to gather information on sites visited by you. Services that provide anonymity disable pop-up windows and cookies, and conceal visitor's IP address.
These services typically use a proxy server to process each HTTP request. When the user requests a Web page by clicking a hyperlink or typing a URL into their browser, the service retrieves and displays the information using its own server. The remote server (where the requested Web page resides) receives information on the anonymous Web surfing service in place of your information.
In which situations would you want to use anonymizer? (Select 3 answers)- AA. Increase your Web browsing bandwidth speed by using Anonymizer
- BB. To protect your privacy and Identity on the Internet
- CC. To bypass blocking applications that would prevent access to Web sites or parts of sites that you want to visit.

Lori is then given permission to search through the corporate email system. She searches by email being sent to and sent
from the rival marketing company.
She finds one employee that appears to be sending very large email to this other marketing company, even
though they should have no reason to be communicating with them. Lori tracks down the actual emails sent
and upon opening them, only finds picture files attached to them. These files seem perfectly harmless,
usually containing some kind of joke. Lori decides to use some special software to further examine the
pictures and finds that each one had hidden text that was stored in each picture.

You are the security administrator of Jaco Banking Systems located in Boston. You are setting up ebanking website (http://www.ejacobank.com) authentication system. Instead of issuing banking customer with a single password, you give them a printed list of 100 unique passwords. Each time the customer needs to log into the e-banking system website, the customer enters the next password on the list. If someone sees them type the password using shoulder surfing, MiTM or keyloggers, then no damage is done because the password will not be accepted a second time. Once the list of 100 passwords is almost finished, the system automatically sends out a new password list by encrypted e-mail to the customer.
You are confident that this security implementation will protect the customer from password abuse.
Two months later, a group of hackers called "HackJihad" found a way to access the one-time password list issued to customers of Jaco Banking Systems. The hackers set up a fake website (http://www.e-jacobank.com) and used phishing attacks to direct ignorant customers to it. The fake website asked users for their ebanking username and password, and the next unused entry from their one-time password sheet. The hackers collected 200 customer's username/passwords this way. They transferred money from the customer's bank account to various offshore accounts.

You immediately shut down the e-banking website while figuring out the next best security solution What effective security solution will you recommend in this case?- AA. Implement Biometrics based password authentication system. Record the customers face image to the authentication database
- BB. Configure your firewall to block logon attempts of more than three wrong tries
- CC. Enable a complex password policy of 20 characters and ask the user to change the password
immediately after they logon and do not store password histories - DD. Implement RSA SecureID based authentication system
17QUESTION 17
More sophisticated IDSs look for common shellcode signatures. But even these systems can be bypassed, by using polymorphic shellcode. This is a technique common among virus writers ?it basically hides the true nature of the shellcode in different disguises. How does a polymorphic shellcode work?- AA.

31The SYN flood attack sends TCP connections requests faster than a machine can process them.
Attacker creates a random source address for each packet
SYN flag set in each packet is a request to open a new connection to the server from the spoofed IP
address
Victim responds to spoofed IP address, then waits for confirmation that never arrives (timeout wait is
about 3 minutes)
Victim's connection table fills up waiting for replies and ignores new connections
Legitimate users are ignored and will not be able to access the server
How do you protect your network against SYN Flood attacks?- ASYN cookies. Instead of allocating a record, send a SYN-ACK with a carefully constructed sequence
number generated as a hash of the clients IP address, port number, and other information. When the
client responds with a normal ACK, that special sequence number will be included, which the server
then verifies. Thus, the server first allocates memory on the third packet of the handshake, not the first - BRST cookies - The server sends a wrong SYN/ACK back to the client. The client should then generate a
RST packet telling the server that something is wrong. At this point, the server knows the client is valid
and will now accept incoming connections from that client normally - CCheck the incoming packet's IP address with the SPAM database on the Internet and enable the filter
using ACLs at the Firewall - DStack Tweaking. TCP stacks can be tweaked in order to reduce the effect of SYN floods.
Reduce the timeout before a stack frees up the memory allocated for a connection - EMicro Blocks. Instead of allocating a complete connection, simply allocate a micro record of 16- bytes
for the incoming SYN object
- ASYN cookies. Instead of allocating a record, send a SYN-ACK with a carefully constructed sequence
32What type of port scan is shown below?
- AIdle Scan
- BFIN Scan
- CXMAS Scan
- DWindows Scan

59A common technique for luring e-mail users into opening virus-launching attachments is to send messages
that would appear to be relevant or important to many of their potential recipients. One way of
accomplishing this feat is to make the virus-carrying messages appear to come from some type of business
entity retailing sites, UPS, FEDEX, CITIBANK or a major provider of a common service.
Here is a fraudulent e-mail claiming to be from FedEx regarding a package that could not be delivered. This
mail asks the receiver to open an attachment in order to obtain the FEDEX tracking number for picking up
the package. The attachment contained in this type of e-mail activates a virus.
Vendors send e-mails like this to their customers advising them not to open any files attached with the mail,
as they do not include attachments.
Fraudulent e-mail and legit e-mail that arrives in your inbox contain the fedex.com as the sender of the mail.
How do you ensure if the e-mail is authentic and sent from fedex.com?
- AVerify the digital signature attached with the mail, the fake mail will not have Digital ID at all

66Cyber Criminals have long employed the tactic of masking their true identity. In IP spoofing, an attacker
gains unauthorized access to a computer or a network by making it appear that a malicious message has
come from a trusted machine, by "spoofing" the IP address of that machine.
How would you detect IP spoofing?- ACheck the IPID of the spoofed packet and compare it with TLC checksum. If the numbers match then it
is spoofed packet - BProbe a SYN Scan on the claimed host and look for a response SYN/FIN packet, if the connection
completes then it is a spoofed packet - CTurn on 'Enable Spoofed IP Detection' in Wireshark, you will see a flag tick if the packet is spoofed
- DSending a packet to the claimed host will result in a reply. If the TTL in the reply is not the same as the
packet being checked then it is a spoofed packet
- ACheck the IPID of the spoofed packet and compare it with TLC checksum. If the numbers match then it

71Fake Anti-Virus, is one of the most frequently encountered and persistent threats on the web. This malware
uses social engineering to lure users into infected websites with a technique called Search Engine
Optimization.
Once the Fake AV is downloaded into the user's computer, the software will scare them into believing their
system is infected with threats that do not really exist, and then push users to purchase services to clean up
the non-existent threats.
The Fake AntiVirus will continue to send these annoying and intrusive alerts until a payment is made.
What is the risk of installing Fake AntiVirus?

76Samuel is the network administrator of DataX Communications, Inc. He is trying to configure his firewall to
block password brute force attempts on his network. He enables blocking the intruder's IP address for a
period of 24 hours' time after more than three unsuccessful attempts. He is confident that this rule will
secure his network from hackers on the Internet.
But he still receives hundreds of thousands brute-force attempts generated from various IP addresses
around the world. After some investigation he realizes that the intruders are using a proxy somewhere else
on the Internet which has been scripted to enable the random usage of various proxies on each request so
as not to get caught by the firewall rule.
Later he adds another rule to his firewall and enables small sleep on the password attempt so that if the
password is incorrect, it would take 45 seconds to return to the user to begin another attempt. Since an
intruder may use multiple machines to brute force the password, he also throttles the number of
connections that will be prepared to accept from a particular IP address.
This action will slow the intruder's attempts.
Samuel wants to completely block hackers brute force attempts on his network.
What are the alternatives to defending against possible brute-force password attacks on his site?- AEnforce a password policy and use account lockouts after three wrong logon attempts even though this might lock out legit users
- BEnable the IDS to monitor the intrusion attempts and alert you by e-mail about the IP address of the intruder so that you can block them at the Firewall manually
- CEnforce complex password policy on your network so that passwords are more difficult to brute force
- DYou cannot completely block the intruders attempt if they constantly switch proxies

83Bret is a web application administrator and has just read that there are a number of surprisingly common
web application vulnerabilities that can be exploited by unsophisticated attackers with easily available tools
on the Internet. He has also read that when an organization deploys a web application, they invite the world
to send HTTP requests. Attacks buried in these requests sail past firewalls, filters, platform hardening, SSL,
and IDS without notice because they are inside legal HTTP requests. Bret is determined to weed out
vulnerabilities.

124Leesa is the senior security analyst for a publicly traded company. The IT department recently rolled out an
intranet for company use only with information ranging from training, to holiday schedules, to human
resources data. Leesa wants to make sure the site is not accessible from outside and she also wants to
ensure the site is Sarbanes-Oxley (SOX) compliant. Leesa goes to a public library as she wants to do some
Google searching to verify whether the company's intranet is accessible from outside and has been indexed
by Google. Leesa wants to search for a website title of "intranet" with part of the URL containing the word
"intranet" and the words "human resources" somewhere in the webpage.

126Hampton is the senior security analyst for the city of Columbus in Ohio. His primary responsibility is to
ensure that all physical and logical aspects of the city's computer network are secure from all angles. Bill is
an IT technician that works with Hampton in the same IT department. Bill's primary responsibility is to keep
PC's and servers up to date and to keep track of all the agency laptops that the company owns and lends
out to its employees. After Bill setup a wireless network for the agency, Hampton made sure that everything
was secure. He instituted encryption, rotating keys, turned off SSID broadcasting, and enabled MAC
filtering. According to agency policy, only company laptops are allowed to use the wireless network, so
Hampton entered all the MAC addresses for those laptops into the wireless security utility so that only those
laptops should be able to access the wireless network.
Hampton does not keep track of all the laptops, but he is pretty certain that the agency only purchases Dell
laptops. Hampton is curious about this because he notices Bill working on a Toshiba laptop one day and
saw that he was on the Internet. Instead of jumping to conclusions, Hampton decides to talk to Bill's boss
and see if they had purchased a Toshiba laptop instead of the usual Dell. Bill's boss said no, so now
Hampton is very curious to see how Bill is accessing the Internet. Hampton does site surveys every couple
of days, and has yet to see any outside wireless network signals inside the company's building.
How was Bill able to get Internet access without using an agency laptop?- ABill spoofed the MAC address of Dell laptop
- BBill connected to a Rogue access point
- CToshiba and Dell laptops share the same hardware address
- DBill brute forced the Mac address ACLs

resources the user account has access to. But Jess is not picking up hashes from the network. Why?- AThe network protocol is configured to use SMB Signing
- BThe physical network wire is on fibre optic cable
- CThe network protocol is configured to use IPSEC
- DL0phtCrack SMB sniffing only works through Switches and not Hubs
130Harold works for Jacobson Unlimited in the IT department as the security manager. Harold has created a
security policy requiring all employees to use complex 14 character passwords. Unfortunately, the members
of management do not want to have to use such long complicated passwords so they tell Harold's boss this
new password policy should not apply to them. To comply with the management's wishes, the IT
department creates another Windows domain and moves all the management users to that domain. This
new domain has a password policy only requiring 8 characters.
Harold is concerned about having to accommodate the managers, but cannot do anything about it. Harold
is also concerned about using LanManager security on his network instead of NTLM or NTLMv2, but the
many legacy applications on the network prevent using the more secure NTLM and NTLMv2. Harold pulls
the SAM files from the DC's on the original domain and the new domain using Pwdump6.
Harold uses the password cracking software John the Ripper to crack users' passwords to make sure they
are strong enough. Harold expects that the users' passwords in the original domain will take much longer to
crack than the management's passwords in the new domain. After running the software, Harold discovers
that the 14 character passwords only took a short time longer to crack than the 8 character passwords.
Why did the 14 character passwords not take much longer to crack than the 8 character passwords?- AHarold should have used Dumpsec instead of Pwdump6
- BHarold's dictionary file was not large enough
- CHarold should use LC4 instead of John the Ripper
- DLanManger hashes are broken up into two 7 character fields

148One of the ways to map a targeted network for live hosts is by sending an ICMP ECHO request to the
broadcast or the network address. The request would be broadcasted to all hosts on the targeted network.
The live hosts will send an ICMP ECHO Reply to the attacker's source IP address.
You send a ping request to the broadcast address 192.168.5.255
There are 40 computers up and running on the target network. Only 13 hosts send a reply while others do
not. Why?
- AWindows machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed
at the broadcast address or at the network address - BLinux machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed at
the broadcast address or at the network address - CYou should send a ping request with this command ping ? 192.168.5.0-255
- DYou cannot ping a broadcast address. The above scenario is wrong
- AWindows machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed
