Cyber Security Essentials

What is Two-Factor Authentication (2FA)?

• A method to encrypt data using a single password.

• A technique that requires a security question for login.

• Two-Factor Authentication (2FA) is a security measure that requires two forms of identification for account access.

• A process that only uses biometric data for authentication.

Why is Two-Factor Authentication important for security?

• Two-Factor Authentication is important for security because it provides an additional layer of protection against unauthorized access.

• It slows down the login process without any benefits.

• It is only necessary for financial accounts.

• It eliminates the need for passwords entirely.

What are common methods used in Two-Factor Authentication?

• IP address whitelisting

• Single sign-on solutions

• Common methods used in Two-Factor Authentication include SMS codes, authenticator apps, email codes, hardware tokens, and biometric verification.

• Password complexity requirements

What is phishing and how does it work?

• Phishing is a type of computer virus that infects devices.

• Phishing is a method of securing sensitive information through encryption.

• Phishing is a legitimate marketing strategy used by companies.

• Phishing is a cyber attack that deceives individuals into revealing sensitive information.

What are some signs of a phishing email?

• Emails with personalized greetings

• Signs of a phishing email include poor spelling and grammar, generic greetings, urgent requests for personal information, mismatched email addresses, and suspicious links or attachments.

• Requests for feedback on services

• Attachments from known contacts

How can you protect yourself from phishing attacks?

• Verify sender's email, avoid suspicious links, use two-factor authentication, keep software updated, and educate yourself.

• Use the same password for all accounts

• Ignore all emails from unknown senders

• Click on all links in emails to verify them

What is data encryption?

• Data encryption is the process of deleting data permanently.

• Data encryption is a method of increasing data storage capacity.

• Data encryption is the act of compressing data for faster access.

• Data encryption is the process of converting data into a coded format to protect it from unauthorized access.

What are the two main types of encryption?

• Symmetric encryption and asymmetric encryption

• Data encryption and file encryption

• Public key encryption and private key encryption

• Block encryption and stream encryption

How does symmetric encryption differ from asymmetric encryption?

• Asymmetric encryption is faster than symmetric encryption for all types of data.

• Symmetric encryption uses two keys for encryption and decryption.

• Symmetric encryption uses one key for both encryption and decryption, while asymmetric encryption uses a pair of keys.

• Symmetric encryption is only used for digital signatures.

What are the best practices for creating a secure password?

• Use only lowercase letters

• Change passwords every few years

• Use at least 12 characters with a mix of letters, numbers, and symbols; avoid common words and personal information; update regularly and use unique passwords for each account.

• Share passwords with trusted friends
