1. What is the importance of regularly updating an operating system to maintain security?
Regular updates provide patches for vulnerabilities, improving security and addressing potential
exploits that attackers may use.
2. How can you ensure that user accounts have the minimum necessary permissions in Windows?
By applying the principle of least privilege, only granting users permissions necessary to perform
their tasks and using User Account Control (UAC) for additional oversight.
3. What role do antivirus software and firewalls play in securing an operating system?
Antivirus software detects and removes malware, while firewalls monitor and control incoming
and outgoing network traffic to block unauthorized access.
4. Why should strong passwords be enforced on all user accounts?
Strong passwords are essential to prevent unauthorized access, ensuring that accounts are not
easily compromised by brute-force attacks.
5. What is the purpose of encryption in securing data on an operating system?
Encryption protects sensitive data by converting it into unreadable format, ensuring that it
cannot be accessed without the decryption key.
6. How does multi-factor authentication (MFA) enhance security?
MFA requires users to provide multiple forms of verification, such as a password and a physical
token, significantly reducing the risk of unauthorized access.
7. What is the best practice for securing user accounts on a Windows system?
1
, Enforce complex passwords, use account lockout policies, and disable unused accounts to
minimize security risks.
8. What are the security risks of using default administrator accounts in operating systems?
Default administrator accounts are well-known and commonly targeted by attackers, so it's
critical to rename, disable, or apply strong security settings to these accounts.
9. Why is disabling unused services and features a recommended security practice?
Disabling unused services reduces the attack surface by minimizing the number of potential entry
points for attackers.
10. What is the significance of securing the boot process in an operating system?
Securing the boot process ensures that the operating system starts in a trusted state, preventing
attackers from inserting malicious code into the startup sequence.
11. How does enabling automatic updates contribute to system security?
Automatic updates ensure that security patches are installed as soon as they are available,
reducing the system's exposure to known vulnerabilities.
12. What is a security risk associated with enabling file sharing on a network?
Enabling file sharing without proper security settings can expose sensitive data to unauthorized
access and increase the risk of malware spreading across the network.
13. What is a security practice when dealing with removable media, such as USB drives?
Use antivirus software to scan removable media for malware before transferring files, and limit
the use of USB drives to trusted sources.
14. How can you ensure secure remote access to an operating system?
Use Virtual Private Networks (VPNs), strong authentication methods, and encryption to secure
remote access to the system.
