Cybersecurity v1.1 Pre-Test

Cybersecurity v1.1  Pre-Test

1 - What is a concern when a company has a cloud-based infrastructure as part of its IT infrastructure?

The company shares the security footprint with other companies.

More downtime is possible as a result of the borderless infrastructure.

Software as a service (SaaS) is not easy to implement.

Email becomes more prone to attack.

2 - True or False?

A computer teacher posted a photo on a social media site. Later, the teacher decided to close the account on the social media site. The teacher deleted all the content posted on the site including media and links. The teacher then canceled the account. The photo is now no longer accessible on the Internet.

true

false

3 - Traditionally, network personnel have the mindset of protecting the network border. What changes may be necessary when software as a service (SaaS) is used?

Manipulated data must be static.

Email must be protected to a greater degree.

Security policies may need to be different if the data travels through the cloud.

Social network site access time is greatly degraded due to the amount of processing required for the SaaS application being in the cloud.

4 - When describing malware, what is a difference between a virus and a worm?

A virus replicates itself by attaching to another file whereas a worm can replicate itself independently.

A virus focuses on gaining privileged access to a device whereas a worm does not.

A virus can be used to deliver advertisements without user consent whereas a worm cannot.

A virus can be used to launch a DoS attack (but not a DDoS), but a worm can be used to launch both DoS and DDoS attacks.
