Information Security Questions
-
wishing
-
Vishing
-
Viking
-
Fishing
B
Correct answer
Explanation
Vishing is the correct term - it combines 'voice' and 'phishing'. This attack uses VoIP phone systems to deceive victims into revealing personal information, often by spoofing caller ID to appear as legitimate organizations. The other options are incorrect: 'wishing' is unrelated, 'Viking' refers to Norse seafarers, and 'Fishing' is the actual activity (the cybercrime is 'phishing' with a 'ph').
-
A code generation technique
-
A sequence of fibonacci series
-
A portable vault used to hide secret messages
-
None of these
C
Correct answer
Explanation
A Cryptex is a fictional portable vault with a cylindrical combination lock, introduced in Dan Brown's novel 'The Da Vinci Code.' The word is a portmanteau of 'cryptology' and 'codex' - it can only be opened with the correct password, and breaking it destroys the message inside.
-
A malicious techique of tricking web users into revealing confidential information
-
A device that sends and receivers data in a bit second
-
A form of computer engineering
-
A digital process that in used to display an image on the monitor
-
Spamming
-
Spoofing
-
Bombing
-
Spawning
B
Correct answer
Explanation
Email spoofing is the practice of altering email header information to make the message appear to come from a known or trusted source. This is commonly used in phishing attacks and spam campaigns.
-
secure
-
secured
-
security
-
simple
A
Correct answer
Explanation
In HTTPS, the 's' stands for 'secure' - it indicates the connection is encrypted using SSL/TLS protocols. While 'secured' or 'security' might seem logical, the standard abbreviation is simply 'secure'. 'Simple' is incorrect as HTTPS provides more security than HTTP.
-
Process
-
People
-
Product
-
Technology
B
Correct answer
Explanation
People are widely considered the weakest link in security because they can be manipulated, make mistakes, or bypass technical controls through social engineering. Even the most sophisticated security systems can be compromised through human error, phishing attacks, or credential sharing.
-
Intentional, Accidental, Malicious
-
Accidental, Incidental, Deliberate
-
Accidental, Ethical, Intentional
-
Ethical and Non-ethical
C
Correct answer
Explanation
Hacking attempts can be categorized as accidental (unintentional access or exposure), ethical (authorized penetration testing and security research), or intentional (deliberate unauthorized access). This classification framework covers the full spectrum of hacking motivations and methods.
-
One who uses the same tools and techniques as a hacker, but does so in order to disrupt services and bring attention to a political or social cause
-
One who uses hacking skills in a legitimate way to gain a deeper understanding of the subject
-
One who is a skilled hacker who sometimes acts legally, sometimes in good will, and sometimes not
-
An amateur who lacks the ability to write sophisticated hacking programs or exploits on his own. Uses scripts or programs developed by others to attack computer systems and networks.
D
Correct answer
Explanation
A script kiddie is an amateur who lacks technical expertise to develop their own hacking tools or exploits. Instead, they use pre-written scripts and programs created by skilled hackers to attack systems. The term emphasizes their lack of understanding and reliance on existing tools.
-
The shared community concept and interchange of information exposes personal information that can be used in social engineering attacks
-
The rapid integration of new and advanced technology in web services often renders APIs for executable code and automated business processes weak in security and vulnerable to attacks
-
Both of the above
-
Only A
C
Correct answer
Explanation
Web 2.0's community-driven, information-sharing model creates multiple security risks: the exposure of personal data on social platforms facilitates social engineering attacks, while rapid API development often prioritizes functionality over security, creating vulnerabilities in automated processes. Both factors significantly threaten information security.
-
Clickjacking/ Videojacking
-
GIFAR
-
Cross Site Scripting
-
Flash Parameter Injection
B
Correct answer
Explanation
GIFAR is a hacking technique that involves combining a GIF image file with a Java archive (JAR) file. This hybrid file can execute malicious code and potentially steal viewer credentials when loaded in a vulnerable browser.
-
Clickjacking/ Videojacking
-
GIFAR
-
Cross Site Scripting
-
Flash Parameter Injection
B
Correct answer
Explanation
This is a duplicate of question 57468. GIFAR is a hacking technique combining GIF and JAR files that can execute malicious code and steal credentials when rendered by vulnerable browsers.
-
Network based
-
Host based
-
Application based
-
Both A & B
D
Correct answer
Explanation
Data Leakage Prevention (DLP) methods include network-based solutions (monitoring network traffic) and host-based solutions (installed on endpoints). Application-based DLP is also a category, making 'Both A & B' the most accurate single choice.
-
Data at rest, in motion and at endpoints
-
Data in USB, on servers and on paper
-
Both of the above
-
Only data in motion
A
Correct answer
Explanation
Data Leakage Prevention solutions can protect data at rest (stored data), in motion (data being transmitted), and at endpoints (devices where data is accessed). This comprehensive coverage is a key feature of enterprise DLP solutions.
-
Employee Training
-
Defining a company wide policy for data handling
-
Implementing encryption and outbound filtering tools for keywords
-
All of the above
D
Correct answer
Explanation
Besides technical DLP solutions, organizations should implement employee training on data handling, establish company-wide data policies, and use encryption with outbound filtering. A holistic approach combining people, process, and technology is most effective.
-
Phishing
-
E-mail bomb
-
Spam
-
All of the above
D
Correct answer
Explanation
Phishing tricks users into revealing credentials through fake emails, compromising email security. E-mail bombs flood systems with massive volumes to cause denial-of-service. Spam consumes bandwidth and storage, making it harder to identify legitimate emails. All three attack vectors weaken corporate email systems.
