Software-Based Methods & Security Threats

Which software-based method ensures that stolen data is meaningless to third parties unless they have the decryption key?

• Firewall

• Biometrics

• Encryption

• Access rights

Why are biometric devices considered secure?

• They rely on passwords unique to each user.

• Biological data is unique to each user and hard to fake.

• They encrypt data after scanning biological features.

• They monitor real-time network traffic for malicious activity.

Which software-based method quarantines malware found on a computer system?

• Access rights

• Anti-malware software

• Firewall

• Encryption

What does a firewall do to prevent unauthorized access to a system?

• Encrypts all outgoing and incoming traffic

• Scans and deletes malware in real time

• Examines network traffic against defined rules

• Uses biometric data to authenticate users

Uses biometric data to authenticate users

• To monitor real-time network activity

• To prevent users from downloading malware

• To limit access to data based on user roles

• To encrypt sensitive data for additional security

What is a disadvantage of encryption as a security method?

• It is vulnerable to brute force attacks.

• It does not prevent data from being stolen.

• It can slow down network traffic.

• It requires physical security measures to be effective.

Which of the following is an advantage of anti-malware software?

• It provides real-time alerts before malicious files are downloaded.

• It limits access to data based on user identity.

• It uses biometric features for authentication.

• It encrypts all files on a system.

How can security threats impact individuals?

• By damaging organisational reputation

• By causing data to be encrypted without a key

• By enabling identity theft or fraud

• By crashing the organisation’s web servers

Which of the following impacts is specific to organisations due to security threats?

• Loss of personal data

• Identity theft

• Negative reputation leading to loss of profits

• Inability to use biometric authentication

What is the primary function of biometric authentication in data security?

• To encrypt data for network transmission

• To match unique biological data to stored records

• To monitor incoming and outgoing traffic

• To restrict data access based on usernames
