SEC3 LO4 K10 MQF2 Networked device protection measures

What is the primary function of a firewall in network security?

• To filter network traffic and prevent unauthorized access to or from a private network.

• To optimize network performance

• To provide physical security for network devices

• To encrypt all network traffic

Name one popular anti-malware software used for protecting devices.

• Kaspersky

• Avast

• Norton

• Malwarebytes

Why are security updates important for networked devices?

• Security updates slow down networked devices.

• Security updates are only necessary for personal devices.

• Security updates are optional and can be ignored.

• Security updates patch vulnerabilities and protect against cyber attacks.

Explain the concept of data backup strategies in network security.

• Data backup strategies in network security focus on sharing data with unauthorized users

• Data backup strategies involve deleting all data regularly to prevent loss

• Data backup strategies include storing data in a single location without redundancy

• Data backup strategies in network security involve creating copies of important data to prevent loss in case of system failures, cyber attacks, or human errors. These strategies include regular backups, offsite storage, encryption of backup data, testing backups for reliability, and implementing a disaster recovery plan.

What are the benefits of using disk freezing as a protection measure?

• Disk freezing can increase the risk of data corruption

• Disk freezing can prevent malware execution, preserve evidence, and aid in data recovery.

• Disk freezing can only be used on certain types of devices

• Disk freezing can slow down system performance

How does sandboxing contribute to network security?

• Sandboxing creates a secure environment for testing and executing untrusted programs or files.

• Sandboxing increases the risk of malware spreading across the network.

• Sandboxing allows unrestricted access to all network resources.

• Sandboxing slows down network performance due to excessive security measures.

Which networked device protection measure creates a snapshot of the system at a specific point in time?

• Antivirus Software

• Firewall

• Network Backup

• System Restore

What type of threats can a firewall help prevent?
