A company has made the decision to host their own email and basic web services. The administrator needs to set up the external firewall to limit what protocols should be allowed to get to the public part of the company's network. Which ports should the administrator open? (Choose three.)

Blake is in charge of securing all 20 of his company's servers. He has enabled hardware and software firewalls, hardened the operating systems, and disabled all unnecessary services on all the servers. Unfortunately, there is proprietary AS400 emulation software that must run on one of the servers that requires the telnet service to function properly. Blake is especially concerned about this since telnet can be a very large security risk in an organization. Blake is concerned about how this particular server might look to an outside attacker so he decides to perform some footprinting, scanning, and penetration tests on the server. Blake telnets into the server using Port 80 and types in the following command:

HEAD / HTTP/1.0

After pressing enter twice, Blake gets the following results: What has Blake just accomplished?

In the software security development life cyle process, threat modeling occurs in which phase?

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?

If an attacker's computer sends an IPID of 31400 to a zombie (Idle Scanning) computer on an open port, what will be the response?

Which of the following identifies the three modes in which Snort can be configured to run?

What command would you type to OS fingerprint a server using the command line?

Harold just got home from working at Henderson LLC where he works as an IT technician. He was able to get off early because they were not too busy. When he walks into his home office, he notices his teenage daughter on the computer, apparently chatting with someone online. As soon as she hears Harold enter the room, she closes all her windows and tries to act like she was playing a game. When Harold asks her what she was doing, she acts very nervous and does not give him a straight answer. Harold is very concerned because he does not want his daughter to fall victim to online predators and the sort. Harold doesn't necessarily want to install any programs that will restrict the sites his daughter goes to, because he doesn't want to alert her to his trying to figure out what she is doing. Harold wants to use some kind of program that will track her activities online, and send Harold an email of her activity once a day so he can see what she has been up to. What kind of software could Harold use to accomplish this?

A hacker, who posed as a heating and air conditioning specialist, was able to install a sniffer program in a switched environment network. Which attack could the hacker use to sniff all of the packets in the network?

Which type of password cracking technique works like dictionary attack but adds some numbers and symbols to the words from the dictionary and tries to crack the password?

Oregon Corp is fighting a litigation suit with Scamster Inc. Oregon has assigned a private investigative agency to go through garbage, recycled paper, and other rubbish at Scamster's office site in order to find relevant information. What would you call this kind of activity?

Which of the following are password cracking tools? (Choose three.)

A computer science student needs to fill some information into a secured Adobe PDF job application that was received from a prospective employer. Instead of requesting a new document that allowed the forms to be completed, the student decides to write a script that pulls passwords from a list of commonly used passwords to try against the secured PDF until the correct password is found or the list is exhausted.

Which cryptography attack is the student attempting?

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?

John runs a Web server, IDS and firewall on his network. Recently his Web server has been under constant hacking attacks. He looks up the IDS log files and sees no intrusion attempts but the Web server constantly locks up and needs rebooting due to various brute force and buffer overflow attacks but still the IDS alerts no intrusion whatsoever. John becomes suspicious and views the Firewall logs and he notices huge SSL connections constantly hitting his Web server. Hackers have been using the encrypted HTTPS protocol to send exploits to the Web server and that was the reason the IDS did not detect the intrusions. How would John protect his network from these types of attacks?

What is the broadcast address for the subnet 190.86.168.0/22?

What type of port scan is represented here.

The GET method should never be used when sensitive data such as credit card is being sent to a CGI program. This is because any GET command will appear in the URL, and will be logged by any servers. For example, let's say that you've entered your credit card information into a form that uses the GET method. The URL may appear like this:

https://www.xsecurity-bank.com/creditcard.asp?cardnumber=453453433532234

The GET method appends the credit card number to the URL. This means that anyone with access to a server log will be able to obtain this information. How would you protect from this type of attack?
