S6 Cyber Security Flashcards
What is computer security and why is it important?
Computer security involves protecting computer systems and information from harm, theft, and unauthorized use. It is important to safeguard sensitive data and ensure the smooth operation of services.
How does a firewall help secure a computer system?
A firewall monitors and controls incoming and outgoing network traffic based on security rules.
Example: Blocking unauthorized access while permitting legitimate communication.
What role does antivirus software play in securing a computer system?
Antivirus software detects, prevents, and removes malware.
Example: Regularly scanning files and quarantining infected ones to prevent damage.
How does encryption contribute to computer security?
Encryption converts data into a coded format to prevent unauthorized access.
Example: Using encryption for email communications and storing sensitive information.
Why are strong passwords and multi-factor authentication important for security?
Strong Passwords: They are difficult to guess, usually containing a mix of letters, numbers, and symbols. Multi-Factor Authentication (MFA): Requires more than one method of authentication to verify a user.
Example: Passwords like P@ssw0rd123! and MFA involving both a password and a code sent to a phone.
What is the significance of regular software updates and patching?
Regularly updating software fixes security vulnerabilities.
Example: Installing security patches for operating systems and applications.
How does data backup enhance security?
Regularly backing up data ensures recovery from data loss or corruption.
Example: Using cloud storage or external hard drives for backups.
Why is education and training important in cybersecurity?
Educating users about cybersecurity best practices helps prevent attacks.
Example: Training employees on how to recognize phishing attempts and avoid social engineering attacks.
Summarize the importance of a multi-layered approach to secure computer systems.
Implementing firewalls, antivirus software, encryption, strong passwords, regular updates, data backups, and user education collectively provide robust protection against threats.
