CCST - Cisco Certified Support Technician Endpoint Operating System Security Questions and Answers 1

Question 1

A user's computer is running unusually slow, and they are seeing frequent, unwanted pop-up advertisements. A support technician suspects a malware infection. What is the most appropriate FIRST action to take?

Accepted Answer

Update the antivirus definitions and perform a full system scan.

Answer

The symptoms are classic indicators of a malware infection. The standard and most effective first step is to update the antivirus or antimalware software to ensure it can recognize the latest threats and then initiate a full system scan to detect and quarantine the malicious software.

Question 2

What is the primary function of a host-based firewall on an end-user's computer?

Accepted Answer

To inspect and filter network traffic entering and leaving that specific device.

Answer

A host-based firewall is a software application that runs on an individual computer or device. Its main purpose is to monitor and control the network traffic for that specific host, allowing or blocking connections based on a defined set of security rules.

Question 3

Which of the following is the MOST critical reason for an organization to consistently apply operating system security patches?

Accepted Answer

To remediate known vulnerabilities that could be exploited by attackers.

Answer

While patches can offer performance improvements and new features, their most critical security function is to fix known vulnerabilities. Attackers actively seek out and exploit these unpatched weaknesses to compromise systems, making timely patching a crucial defensive measure.

Question 4

A company enforces a policy where employees use standard user accounts for daily tasks. When they need to install new software, they are prompted to enter administrator credentials. This practice is a direct implementation of which security principle?

Accepted Answer

Principle of Least Privilege

Answer

The Principle of Least Privilege (PoLP) states that a user or process should only have the minimum level of access (privileges) necessary to perform its required functions. By using a standard account for normal work, the potential damage from a compromised account is significantly limited.

Question 5

In the context of endpoint operating system security, what does the term 'hardening' primarily refer to?

Accepted Answer

Reducing the system's attack surface by disabling unnecessary services and features.

Answer

Operating System (OS) hardening is the process of securing a system by minimizing its attack surface. This is achieved by removing non-essential software, disabling unnecessary services, closing unused ports, and configuring security settings to be more restrictive.
