Bret 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.
What are some of the common vulnerabilities in web applications that he should be concerned about?
A. Non-validated parameters,broken access control,broken account and session management,cross-site scripting and buffer overflows are just a few common vulnerabilities
B. Visible clear text passwords,anonymous user account set as default,missing latest security patch,no firewall filters set and no SSL configured are just a few common vulnerabilities
C. No SSL configured,anonymous user account set as default,missing latest security patch,no firewall filters set and an inattentive system administrator are just a few common vulnerabilities
D. No IDS configured,anonymous user account set as default,missing latest security patch,no firewall filters set and visible clear text passwords are just a few common vulnerabilities
What is War Dialing?
A. War dialing involves the use of a program in conjunction with a modem to penetrate the modem/PBX-based systems

C. It is a social engineering technique that uses Phone calls to trick victims
D. Involves IDS Scanning Fragments to bypass Internet filters and stateful Firewalls
Steven the hacker realizes the network administrator of Acme Corporation is using syskey in Windows 2008 Server to protect his resources in the organization. Syskey independently encrypts the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the passwords. Steven must break through the encryption used by syskey before he can attempt to use brute force dictionary attacks on the hashes. Steven runs a program called “SysCracker” targeting the Windows 2008 Server machine in attempting to crack the hash used by Syskey. He needs to configure the encryption level before he can launch the attack. How many bits does Syskey use for encryption?
A. 40-bit encryption
B. 128-bit encryption
C. 256-bit encryption
D. 64-bit encryption

BankerFox is a Trojan that is designed to steal users’ banking data related to certain banking entities.
When they access any website of the affected banks through the vulnerable Firefox 3.5 browser, the Trojan is activated and logs the information entered by the user. All the information entered in that website will be logged by the Trojan and transmitted to the attacker’s machine using covert channel.
BankerFox does not spread automatically using its own means. It needs an attacking user’s intervention in order to reach the affected computer.
What is the most efficient way an attacker located in remote location to infect this banking Trojan on a victim’s machine?
A. Physical access – the attacker can simply copy a Trojan horse to a victim’s hard disk infecting the machine via Firefox add-on extensions
B. Custom packaging – the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer
C. Custom packaging – the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer
D. Custom packaging – the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer
E. Downloading software from a website? An attacker can offer free software,such as shareware programs and pirated mp3 files
In the context of password security: a simple dictionary attack involves loading a dictionary file (a text file full of dictionary words) into a cracking application such as L0phtCrack or John the Ripper, and running it against user accounts located by the application. The larger the word and word fragment selection, the more effective the dictionary attack is. The brute force method is the most inclusive – though slow. Usually, it tries every possible letter and number combination in its automated exploration. If you would use both brute force and dictionary combined together to have variations of words, what would you call such an attack?
A. Full Blown Attack
B. Thorough Attack
C. Hybrid Attack
D. BruteDict Attack
