System Security Configuration

5 minutes 5 Questions

System Security Configuration is the process of configuring a computer system to protect it from unauthorized access, data loss, and malware. This includes actions such as setting up user account control, configuring operating system security settings, implementing data encryption, and enabling firewalls and antivirus software. Proper system security configuration is essential for safeguarding sensitive information and maintaining the integrity of the system. It is increasingly important in a world where cyberthreats are constantly evolving. Technicians must understand the principles of system security configuration to identify vulnerabilities, apply patches and updates, and enforce best practices for cybersecurity.

Guide to System Security Configuration - CompTIA A+

What is System Security Configuration?
System Security Configuration in CompTIA A+ refers to the set of rules and settings defined to secure a computer system or network. These include permissions, password policies, network settings, software installations, and firewall configurations.

Its Importance:
It's crucial for maintaining confidentiality, integrity, and availability of systems and data. Failure in securing configurations can result in data breaches, loss of data, unauthorized system access, or even system malfunctions.

How it Works:
System Security Configuration works by setting up the rules and protocols concerning the usage of system resources. This involves defining what a user can do, which resources a user can access, and other setting configurations necessary to protect the system from security threats.

Exam Tips:
When answering questions on System Security Configuration in the exam, remember the following tips:
1. Understand the key concepts of System Security Configuration.
2. Focus on real-world scenarios, think how an IT professional configures system security in a practical environment.
3. When asked for defining the best security practice, remember it is about providing maximum security while maintaining system functionality.
4. Remember to stay updated with the latest security measures and policies.

CompTIA A+ - System Configuration Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

A manager asks you to set up a file-share server for the team. What should you do to enhance server security?

Correct Answer: Implement role-based access control

Implementing role-based access control provides users with access rights based on their job responsibilities, ensuring that unauthorized individuals cannot access sensitive data. Giving administrative rights, disabling antivirus, or removing authentication requirements would all compromise security.

Question 2

An organization wants its employees to securely access internal resources remotely. What solution should be implemented?

Correct Answer: Set up a VPN

Setting up a VPN (Virtual Private Network) is the best solution for securely accessing internal resources remotely. A VPN establishes an encrypted tunnel between the employee's device and the organization's network, ensuring that all data transmitted is protected from unauthorized access. Forwarding external IP addresses to internal resources would expose those resources to the internet, making them vulnerable to attacks. Storing sensitive data on employees' local machines is not secure, as those devices may be lost, stolen, or compromised. Turning off all firewalls would remove a critical layer of network security, leaving the organization open to various threats.

Question 3

During a routine system check, you notice repeated unauthorized login attempts on a computer. What is the first step you should take to enhance the system security?

Correct Answer: Enable account lockout policy

Enabling an account lockout policy will stop further unauthorized access attempts by locking the account after a certain number of failed attempts. Disconnecting the network or changing the IP address will not necessarily stop the attempts, and other options do not directly address the issue at hand.
