Wayne is the senior security analyst for his company. Wayne is examining some traffic logs on a server and came across some inconsistencies. Wayne finds some IP packets from a computer purporting to be on the internal network. The packets originate from 192.168.12.35 with a TTL of 15. The server replied to this computer and received a response from 192.168.12.35 with a TTL of 21. What can Wayne infer from this traffic log?
Jeremy is web security consultant for Information Securitas. Jeremy has just been hired to perform contract work for a large state agency in Michigan. Jeremy's first task is to scan all the company's external websites. Jeremy comes upon a login page which appears to allow employees access to sensitive areas on the website. James types in the following statement in the username field:

Hayden is the network security administrator for her company, a large finance firm based in Miami. Hayden just returned from a security conference in Las Vegas where they talked about all kinds of old and new security threats; many of which she did not know of. Hayden is worried about the current security state of her company's network so she decides to start scanning the network from an external IP address. To see how some of the hosts on her network react, she sends out SYN packets to an IP range. A number of IPs responds with a SYN/ACK response. Before the connection is established she sends RST packets to those hosts to stop the session. She does this to see how her intrusion detection system will log the traffic. What type of scan is Hayden attempting here?
Lauren is performing a network audit for her entire company. The entire network is comprised of around 500 computers. Lauren starts an ICMP ping sweep by sending one IP packet to the broadcast address of the network, but only receives responses from around five hosts. Why did this ping sweep only produce a few responses?
Blane is a security analyst for a law firm. One of the lawyers needs to send out an email to a client but he wants to know if the email is forwarded on to any other recipients. The client is explicitly asked not to re-send the email since that would be a violation of the lawyer's and client's agreement for this particular case. What can Blane use to accomplish this?
What command would you type to OS fingerprint a server using the command line?
The SNMP Read-Only Community String is like a password. The string is sent along with each SNMP Get-Request and allows (or denies) access to a device. Most network vendors ship their equipment with a default password of "public". This is the so-called "default public community string". How would you keep intruders from getting sensitive information regarding the network devices using SNMP? (Select 2 answers)
Which of the following conditions must be given to allow a tester to exploit a Cross-Site Request Forgery (CSRF) vulnerable web application?
Bank of Timbuktu is a medium-sized, regional financial institution in Timbuktu. The bank has deployed a new Internet-accessible Web application recently. Customers can access their account balances, transfer money between accounts, pay bills and conduct online financial business using a Web browser.
John Stevens is in charge of information security at Bank of Timbuktu. After one month in production, several customers have complained about the Internet enabled banking application. Strangely, the account balances of many of the bank's customers had been changed! However, money hasn't been removed from the bank; instead, money was transferred between accounts. Given this attack profile, John Stevens reviewed the Web application's logs and found the following entries:
What kind of attack did the Hacker attempt to carry out at the bank?
You are trying to package a RAT Trojan so that Anti-Virus software will not detect it. Which of the listed technique will NOT be effective in evading Anti-Virus scanner?
You want to perform advanced SQL Injection attack against a vulnerable website. You are unable to perform command shell hacks on this server. What must be enabled in SQL Server to launch these attacks?
When an alert rule is matched in a network-based IDS like snort, the IDS does which of the following?
Which of the following types of firewall inspects only header information in network traffic?
NTP allows you to set the clocks on your systems very accurately, to within 100ms and sometimes-even 10ms. Knowing the exact time is extremely important for enterprise security. Various security protocols depend on an accurate source of time information in order to prevent "playback" attacks. These protocols tag their communications with the current time, to prevent attackers from replaying the same communications, e.g., a login/password interaction or even an entire communication, at a later date. One can circumvent this tagging, if the clock can be set back to the time the communication was recorded. An attacker attempts to try corrupting the clocks on devices on your network. You run Wireshark to detect the NTP traffic to see if there are any irregularities on the network. What port number you should enable in Wireshark display filter to view NTP packets?
Which of the following Exclusive OR transforms bits is NOT correct?
Which of the following are valid types of rootkits? (Choose three.)
Simon is security analyst writing signatures for a Snort node he placed internally that captures all mirrored traffic from his border firewall. From the following signature, what will Snort look for in the payload of the suspected packets?
alert tcp $EXTERNAL_NET any -> $HOME_NET 27374 (msG. "BACKDOOR SIG - SubSseven 22";flags: A+; content: "|0d0a5b52504c5d3030320d0a|"; reference:arachnids, 485;) alert
June, a security analyst, understands that a polymorphic virus has the ability to mutate and can change its known viral signature and hide from signature-based antivirus programs. Can June use an antivirus program in this case and would it be effective against a polymorphic virus?
