📋 Factual

intermediate

What can happen if a network is not secure?

What is a common consequence of having an insecure network?

A Faster data transfer speeds

B Lower electricity consumption

C Increased risk of cyber attacks and data breaches

D Automatic software updates

💡 Hint

Consider what risks come from attackers exploiting weak network defenses.

How does network security protect personal information?

Which method is commonly used in network security to protect personal information during transmission?

A Encryption to scramble data so only authorized users can read it

B Increasing the bandwidth to speed up data transfer

C Disabling firewalls to allow free access

D Using simple passwords for easy login

💡 Hint

Think about how data can be kept safe even if intercepted.

Encryption converts data into a coded form that only authorized users can decode, protecting personal information during transmission.

❓ Comparison

advanced

Which is a stronger network security measure?

Compare the following network security measures. Which one provides stronger protection?

A Using a firewall combined with intrusion detection systems

B Using only a password to protect the network

C Relying on antivirus software alone

D Disabling all security features for easier access

💡 Hint

Consider which option uses multiple layers of defense.

Combining a firewall with intrusion detection systems offers multiple layers of protection, making it harder for attackers to breach the network.

❓ Reasoning

expert

Why is network security essential for protecting critical infrastructure?

Critical infrastructure like power grids and hospitals rely on network security. Why is this protection essential?

A Because it helps reduce the cost of electricity

B Because attacks could disrupt essential services and endanger lives

C Because it makes the network run faster

D Because it allows anyone to access the system easily

💡 Hint

Think about the impact if these systems were attacked or stopped working.

Network security prevents attacks that could disrupt critical services, which could cause serious harm or danger to people.
