You can always defend yourself by “ignorance of the law” clause.

  1. True
  2. False

Answer(s): B

Explanation:

Ignorantia juris non excusat or Ignorantia legis neminem excusat (Latin for "ignorance of the law does not excuse" or "ignorance of the law excuses no one") is a public policy holding that a person who is unaware of a law may not escape liability for violating that law merely because he or she was unaware of its content; that is, persons have presumed knowledge of the law. Presumed knowledge of the law is the principle in jurisprudence that one is bound by a law even if one does not know of it. It has also been defined as the "prohibition of ignorance of the law".



Jake works as a system administrator at Acme Corp. Jason, an accountant of the firm befriends him at the canteen and tags along with him on the pretext of appraising him about potential tax benefits. Jason waits for Jake to swipe his access card and follows him through the open door into the secure systems area. How would you describe Jason's behavior within a security context?

  1. Trailing
  2. Tailgating
  3. Swipe Gating
  4. Smooth Talking

Answer(s): B

Explanation:

Tailgating, in which an unauthorized person follows someone with a pass into an office, is a very simple social engineering attack. The intruder opens the door, which the authorized user walks through, and then engages them in conversation about the weather or weekend sport while they walk past the reception area together.



While testing web applications, you attempt to insert the following test script into the search area on the company's web site:
<script>alert('Testing Testing Testing')</script>
Afterwards, when you press the search button, a pop up box appears on your screen with the text "Testing Testing Testing". What vulnerability is detected in the web application here?

  1. A hybrid attack
  2. A buffer overflow
  3. Password attacks
  4. Cross Site Scripting

Answer(s): D

Explanation:

Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications which allow code injection by malicious web users into the web pages viewed by other users. Examples of such code include HTML code and client-side scripts. An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls such as the same origin policy.

This packet was taken from a packet sniffer that monitors a Web server.
This packet was originally 1514 bytes long, but only the first 512 bytes are shown here. This is the standard hexdump representation of a network packet, before being decoded. A hexdump has three columns: the offset of each line, the hexadecimal data, and the ASCII equivalent. This packet contains a 14-byte Ethernet header, a 20-byte IP header, a 20-byte TCP header, an HTTP header ending in two line-feeds (0D 0A 0D 0A) and then the data. By examining the packet identify the name and version of the Web server?

  1. Apache 1.2
  2. IIS 4.0
  3. IIS 5.0
  4. Linux WServer 2.3

Answer(s): B

Explanation:

We see that the server is Microsoft, but the exam designer didn’t want to make it easy for you. So what they did is blank out the IIS 4.0. The key is in line “0B0” as you see:
0B0 69 63 72 6F 73 6F 66 74 2D 49 49 53 2F 34 2E 30 ..Microsoft
49 is I, so we get II
53 is S, so we get IIS
2F is a space
34 is 4
2E is .
30 is 0
So we get IIS 4.0
The answer is B
If you don’t remember the ASCII hex to Character, there are enough characters and numbers already converted. For example, line “050” has STRIDER which is 53 54 52 49 44 45 52 and gives you the conversion for the “I:” and “S” characters (which is “49” and “53”).
