Question No: 2

MultipleChoice

A security team identified several rogue Wi-Fi access points during the most recent network scan. The network scans occur once per quarter. Which of the following controls would best all ow the organization to identity rogue devices more quickly?

Options

AImplement a continuous monitoring policy.

BImplement a BYOD policy.

CImplement a portable wireless scanning policy.

DChange the frequency of network scans to once per month.

Answer
AExplanation

The best control to allow the organization to identify rogue devices more quickly is

A) Implement a continuous monitoring policy. A continuous monitoring policy is a set of procedures and tools that enable an organization to detect and respond to unauthorized or anomalous activities on its network in real time or near real time. A continuous monitoring policy can help identify rogue access points as soon as they appear on the network, rather than waiting for quarterly or monthly scans.A continuous monitoring policy can also help improve the overall security posture and compliance of the organization by providing timely and accurate information about its network assets, vulnerabilities, threats, and incidents1.

MultipleChoice

An employee is no longer able to log in to an account after updating a browser. The employee usually has several tabs open in the browser. Which of the following attacks was most likely performed?

Options

ARFI

BLFI

CCSRF

DXSS

Answer
CExplanation

The most likely attack that was performed is CSRF (Cross-Site Request Forgery). This is an attack that forces a user to execute unwanted actions on a web application in which they are currently authenticated1. If the user has several tabs open in the browser, one of them might contain a malicious link or form that sends a request to the web application to change the user's password, email address, or other account settings. The web application will not be able to distinguish between the legitimate requests made by the user and the forged requests made by the attacker. As a result, the user will lose access to their account.

To prevent CSRF attacks, web applications should implement some form of anti-CSRF tokens or other mechanisms that validate the origin and integrity of the requests2. These tokens are unique and unpredictable values that are generated by the server and embedded in the forms or URLs that perform state-changing actions. The server will then verify that the token received from the client matches the token stored on the server before processing the request. This way, an attacker cannot forge a valid request without knowing the token value.

Some other possible attacks that are not relevant to this scenario are:

RFI (Remote File Inclusion) is an attack that allows an attacker to execute malicious code on a web server by including a remote file in a script. This attack does not affect the user's browser or account settings.

LFI (Local File Inclusion) is an attack that allows an attacker to read or execute local files on a web server by manipulating the input parameters of a script. This attack does not affect the user's browser or account settings.

XSS (Cross-Site Scripting) is an attack that injects malicious code into a web page that is then executed by the user's browser. This attack can affect the user's browser or account settings, but it requires the user to visit a compromised web page or click on a malicious link. It does not depend on having several tabs open in the browser.

MultipleChoice

A company brings in a consultant to make improvements to its website. After the consultant leaves. a web developer notices unusual activity on the website and submits a suspicious file containing the following code to the security team:

Which of the following did the consultant do?

Implanted a backdoor

Implemented privilege escalation

Implemented clickjacking

Patched the web server

Options

AImplanted a backdoor.
A backdoor is a method that allows an unauthorized user to access a system or network without the permission or knowledge of the owner. A backdoor can be installed by exploiting a software vulnerability, by using malware, or by physically modifying the hardware or firmware of the device. A backdoor can be used for various malicious purposes, such as stealing data, installing malware, executing commands, or taking control of the system.
In this case, the consultant implanted a backdoor in the website by using an HTML and PHP code snippet that displays an image of a shutdown button and an alert message that says ''Exit''. However, the code also echoes the remote address of the server, which means that it sends the IP address of the visitor to the attacker. This way, the attacker can identify and target the visitors of the website and use their IP addresses to launch further attacks or gain access to their devices.
The code snippet is an example of a clickjacking attack, which is a type of interface-based attack that tricks a user into clicking on a hidden or disguised element on a webpage. However, clickjacking is not the main goal of the consultant, but rather a means to implant the backdoor. Therefore, option C is incorrect.
Option B is also incorrect because privilege escalation is an attack technique that allows an attacker to gain higher or more permissions than they are supposed to have on a system or network. Privilege escalation can be achieved by exploiting a software vulnerability, by using malware, or by abusing misconfigurations or weak access controls. However, there is no evidence that the consultant implemented privilege escalation on the website or gained any elevated privileges.
Option D is also incorrect because patching is a process of applying updates to software to fix errors, improve performance, or enhance security. Patching can prevent or mitigate various types of attacks, such as exploits, malware infections, or denial-of-service attacks. However, there is no indication that the consultant patched the web server or improved its security in any way.

Question No: 5

MultipleChoice

The Chief Information Security Officer (CISO) wants the same level of security to be present whether a remote worker logs in at home or at a coffee shop. Which of the following should be recommended as a starting point?

Options

ANon-persistent virtual desktop infrastructures (VDI)

BPasswordless authentication

CStandard-issue laptops

DServerless workloads

Answer
AExplanation

Non-persistent Virtual Desktop Infrastructure (VDI) is the best solution because:

Users access a centrally managed, secure virtual desktop regardless of location.

No data is stored locally, preventing data theft on compromised devices.

Each session is reset upon logout, eliminating malware persistence.

Why Not Other Options?

B (Passwordless authentication) Improves security but does not ensure the same security level across different locations.

C (Standard-issue laptops) Helps with consistency but does not protect against untrusted networks.

D (Serverless workloads) Focuses on application infrastructure, not user security.

Question No: 6

MultipleChoice

A vulnerability scan shows several vulnerabilities. At the same time, a zero-day vulnerability with a CVSS score of 10 has been identified on a web server. Which of the following actions should the security analyst take first?

Options

AContact the web systems administrator and request that they shut down the asset.

BMonitor the patch releases for all items and escalate patching to the appropriate team.

CRun the vulnerability scan again to verify the presence of the critical finding and the zero-day vulnerability.

DForward the advisory to the web security team and initiate the prioritization strategy for the other vulnerabilities.

Answer
AExplanation

A CVSS 10 vulnerability represents a critical security risk, often leading to remote code execution or complete system compromise.

Option A (Shut down the asset) is the best immediate containment action for preventing exploitation.

Option B (Monitor patches) is important but should be done after containment.

Option C (Rescanning) is unnecessary when a high-confidence security advisory has been issued.

Option D (Forwarding advisory) is good practice but does not immediately mitigate the threat.
