Information Security Questions

Multiple choice technology security
  1. Web Applictation Firewall

  2. Application Based Intrusion Detection

  3. Database Monitoring

  4. Virtual Private Lan

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

ModSecurity is an open-source web application firewall (WAF) designed to detect and block threats targeting web applications. The other options are incorrect because it is not an application intrusion detection system, database monitor, or VPN/VLAN solution.

Multiple choice technology security
  1. Back Attack

  2. Unknown Attack

  3. Reverse Attack

  4. Side Channel Attack

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Side-channel attacks exploit physical information leaked by the cryptographic system, such as power consumption, electromagnetic radiation, or execution timing. Other choices like Back, Unknown, or Reverse attacks are not standard terms for physical implementation exploits.

Multiple choice technology security
  1. Previlged User Monitoring

  2. Application Activity Monitoring

  3. Cyberattack Protection

  4. Database Recovery

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Database Activity Monitor (DAM) is designed to monitor, log, and analyze database transactions for compliance and security (such as privileged user and application activity monitoring, and cyberattack protection). Database recovery is a function of database backup/restore systems and DBMS engines, not a DAM tool.

Multiple choice technology security
  1. DREAD

  2. FEAR

  3. SAFE

  4. DEAF

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

DREAD is a computer security threat classification and risk assessment model. It evaluates threats based on five categories: Damage potential, Reproducibility, Exploitability, Affected users, and Discoverability. FEAR, SAFE, and DEAF are distractors and not standard security classification models.

Multiple choice technology security
  1. STRIDE

  2. PRIDE

  3. BRIDE

  4. RIDE

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

STRIDE is a widely recognized threat modeling methodology developed by Microsoft. It helps identify security threats across six categories: Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege. PRIDE, BRIDE, and RIDE are distractors.

Multiple choice technology security
  1. HTTP Parameter Pollution

  2. Session Splitting

  3. Parameter Damage

  4. Parameter Busting

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To solve this question, the user needs to understand the concept of security vulnerabilities related to web applications.

The correct answer is A. HTTP Parameter Pollution.

Explanation:

HTTP Parameter Pollution (HPP) is a security vulnerability that arises when an attacker submits multiple input parameters of the same name to a web application. This can lead to unexpected behaviors on the server-side and client-side, which can then be exploited by attackers to achieve their goals.

Option B, Session Splitting, is not related to the given premise. Session Splitting is a technique used to distribute user sessions across multiple servers to improve performance and scalability.

Option C, Parameter Damage, is not a commonly used term in the field of web application security. It is not related to the given premise.

Option D, Parameter Busting, is not a commonly used term in the field of web application security. It is not related to the given premise.

Therefore, the correct answer is:

The Answer is: A. HTTP Parameter Pollution.

Multiple choice technology security
  1. Clickjacking

  2. RoughJacking

  3. CyberJacking

  4. CrackJacking

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To solve this question, the user needs to have knowledge of web security and common malicious techniques used by hackers.

The technique described in the question is known as "Clickjacking", which is used to trick web users into clicking on a button or link that is disguised as something else, thereby revealing confidential information or taking control of their computer.

Now, let's go through each option and explain why it is right or wrong:

A. Clickjacking: This option is correct. Clickjacking is a malicious technique used by hackers to deceive web users into clicking on a disguised button or link, which results in the user revealing confidential information or giving control of their computer to the attacker.

B. RoughJacking: This option is incorrect. "RoughJacking" is not a known term in web security, and there is no evidence to suggest that it is a malicious technique used by hackers.

C. CyberJacking: This option is incorrect. "CyberJacking" is a broad term that can refer to a range of malicious activities, but it is not specific to the technique described in the question.

D. CrackJacking: This option is incorrect. "CrackJacking" is not a known term in web security, and there is no evidence to suggest that it is a malicious technique used by hackers.

Therefore, the correct answer is: A. Clickjacking.

Multiple choice technology security
  1. Padding Oracle Attack

  2. Padding CBC Attack

  3. Oracle Lockback

  4. Padding Filter

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A Padding Oracle Attack is a well-known cryptographic exploit against block cipher modes of operation (such as CBC mode) that leak information about whether the padding of a decrypted ciphertext is valid. The other options are incorrect or fabricated terms rather than established cryptographic attacks.

Multiple choice technology security
  1. Reverse Engineering Technique

  2. Buffer Overflow Attack Technique

  3. Log Analysing Technique

  4. Data Analysis Technique

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A NOP sled (or NOP slide) is a classic technique used in buffer overflow attacks to execute arbitrary shellcode. It consists of a sequence of NOP (no-operation) instructions placed before the shellcode, allowing the execution flow to safely slide into the payload even if the instruction pointer is redirected to an imprecise address.
