-
Server Misconfigurations
-
Buffer Overflow
-
Brute Force Attacks
-
None of the above
AI Explanation
To answer this question, you need to understand what ASLR (Address Space Layout Randomization) and DEP (Data Execution Prevention) are and what types of attacks they are effective against. Let's go through each option to understand why it is correct or incorrect:
Option A) Server Misconfigurations - ASLR and DEP are not specifically designed to counter server misconfigurations. Although they can add an extra layer of security, they are not primarily targeted at addressing misconfigurations.
Option B) Buffer Overflow - This option is incorrect. ASLR and DEP are specifically designed to counter buffer overflow attacks. ASLR randomizes the memory layout, making it difficult for an attacker to predict the location of certain functions or variables. DEP prevents the execution of code in certain regions of memory, making it harder for an attacker to exploit a buffer overflow vulnerability.
Option C) Brute Force Attacks - This option is incorrect. ASLR and DEP are not designed to counter brute force attacks. Brute force attacks involve trying all possible combinations of passwords or encryption keys until the correct one is found. ASLR and DEP do not directly address this type of attack.
Option D) None of the above - This option is incorrect. ASLR and DEP are effective countermeasures against buffer overflow attacks.
The correct answer is B) Buffer Overflow. This option is correct because ASLR and DEP are designed to counter buffer overflow attacks by randomizing memory layout and preventing the execution of code in certain regions of memory, respectively.
Tina is working on a multi threaded application.The users of the application can specify the duration for which the threads may be put to sleep.If Tina does not perform any input validation,she is most likely to expose her code to ?
-
Session Fixation
-
Cross Side Scripting
-
Denial of Service
-
SQL Injection
AI Explanation
To answer this question, we need to understand the concept of input validation and the potential risks associated with not performing proper input validation.
Input validation is the process of verifying and validating user input to ensure that it meets certain criteria or constraints. It is an important security measure to prevent malicious or unexpected inputs from causing vulnerabilities in the code.
In this scenario, Tina is working on a multi-threaded application where users can specify the duration for which the threads may be put to sleep. If Tina does not perform any input validation, it means that she does not check or sanitize the user input for this duration.
The lack of input validation in this case can expose Tina's code to Denial of Service (DoS) attacks. A Denial of Service attack is a malicious attempt to disrupt the normal functioning of a system or network by overwhelming it with a flood of illegitimate requests or by exploiting vulnerabilities in the system.
By allowing users to specify an arbitrary duration for thread sleep without proper validation, an attacker could potentially input a very large or infinite duration, causing the threads to sleep for an extended period of time or indefinitely. This could lead to resource exhaustion, where the system becomes overwhelmed and unable to handle legitimate requests, ultimately causing a Denial of Service.
Therefore, the correct answer is C) Denial of Service.
Cross site scripting is a type of attack where:
-
Attacker changes the privilege level through a script
-
Attacker uploads a message that contains client side code that attacks anyone that reads it.
-
A script is run at the attackers machine
-
None of the above
It is a good programming practice to prevent Caching of sensitive data at client or proxies by implementing:
-
"Cache-Control: do not-cache, do not save"
-
"Cache-Control: do not-save, do not store"
-
"Cache-Control: no-cache, no store"
-
"Cache-Control: do not cache"
To solve this question, the user needs to know about caching and how to prevent sensitive data from being cached on clients or proxies.
Option A: "Cache-Control: do not-cache, do not save" - This option is not entirely correct. Although the "do not-cache" directive will prevent the client or proxy from caching the data, there is no "do not save" directive in the Cache-Control header field.
Option B: "Cache-Control: do not-save, do not store" - This option is incorrect. There is no "do not-save" or "do not store" directive in the Cache-Control header field.
Option C: "Cache-Control: no-cache, no store" - This option is correct. The "no-cache" directive indicates that the client or proxy should not use a cached copy of the data for subsequent requests, but it should revalidate the data with the origin server. The "no-store" directive indicates that the client or proxy should not store the data in any form of cache. Together, these directives ensure that sensitive data is not cached on the client or proxy.
Option D: "Cache-Control: do not cache" - This option is not entirely correct. The "do not cache" directive will prevent the client or proxy from caching the data, but it does not prevent the data from being stored in other forms of cache.
Therefore, the correct answer is:
The Answer is: C

Applying the most restrictive set of operating system permissions to all application files is an example of what design principle?
-
Least common mechanism Least privilege
-
Least Privilege
-
Separation of duties
-
Weakest link
To solve this question, the user needs to know the different design principles used in system design.
The option that represents the design principle described in the question is:
B. Least Privilege
Explanation:
The principle of least privilege is a design principle in which users, agents, or processes are granted only the necessary permissions to perform their assigned tasks, and no more. This principle is important because it limits the potential damage of a security breach or other security incident. By applying the most restrictive set of operating system permissions to all application files, the system is designed to provide each application with the minimum level of access required to function properly, reducing the potential damage that could occur from a security breach.
Option A, Least common mechanism, is a separate design principle that states that the fewer mechanisms shared by users, the less likely those mechanisms are to be compromised.
Option C, Separation of duties, is a design principle that requires that more than one person be involved in a task to ensure that no single individual has complete control over a process.
Option D, Weakest link, is a design principle that states that security is only as strong as its weakest point. It emphasizes the need to identify and address vulnerabilities in a system to ensure that it is secure overall.
Therefore, the correct answer is:
The Answer is: B. Least Privilege
