Cybersecurity Concepts and Practices

The video tutorial covers various techniques to enhance the security of networks, servers, and devices. It discusses operating system hardening, including applying security updates and enforcing password policies. The tutorial also highlights endpoint security measures, such as using EDR for malware detection and response. Additionally, it covers the importance of firewalls, intrusion prevention systems, and managing open ports. Finally, it addresses software vulnerabilities and the need for regular updates to maintain security.

What is one of the first steps in system hardening for operating systems?

• Installing new hardware

• Changing the user interface

• Applying security updates

• Disabling network access

Which of the following is a recommended practice for securing user accounts?

• Implementing a password policy with complexity requirements

• Using simple passwords

• Sharing passwords among users

• Allowing all users to be administrators

What is Full Disk Encryption (FDE) used for?

• Encrypting email communications

• Encrypting network traffic

• Encrypting the entire drive

• Encrypting individual files only

What does EDR stand for in the context of malware detection?

• Endpoint Detection and Response

• Electronic Data Recovery

• Encrypted Data Relay

• Enhanced Device Recognition

How does EDR enhance security beyond traditional antivirus solutions?

• By using only signature-based detection

• By providing behavioral analysis and machine learning

• By requiring manual updates

• By focusing solely on network traffic

What is the role of a host-based firewall?

• To replace antivirus software

• To monitor and control inbound and outbound traffic

• To block all network traffic

• To allow all network traffic

What is a key function of a host-based intrusion prevention system (HIPS)?

• To provide hardware upgrades

• To disable all network connections

• To monitor and block known vulnerabilities

• To allow all software installations

Why is it important to manage open ports on a system?

• To increase system speed

• To reduce the risk of unauthorized access

• To allow more applications to run

• To improve user interface design

What should be done with default configurations on new devices?

• Leave them unchanged

• Change them to prevent unauthorized access

• Ignore them

• Share them with all users

What is a recommended practice for managing software applications on a system?

• Never update applications

• Install as many applications as possible

• Keep all applications regardless of use

• Delete unused applications to reduce security risks
