University of MelbourneIT VU21990 Q1) State the benefits of backing up data to a cloud-based disk? Q2: What are the drawbacks of backing up data to a local external disk? Q3

Answer:

Q1

• Easier usability and accessibility.
• Enhanced security.
• It is more cost efficient.
• Easy way of sharing files.
• Allow usage of multiple users.
• Facilitate synchronization of both backed up data and available new data.
• Enhanced availability of thbacked up data.

Q2

• They are prone to failure in the sense that the external drives are subject to the same data loss risks as internal drives such as viruses and worms.
• Security is limited since many of the external drives aren't encrypted or password protected.
• File versioning is difficult to set up on external media, and it requires manual cleanup of old files to allow file versioning.
• There is high initial cost of setting up compared to cloud backup since the expense of hardware is more compared to preparing for a cloud based platform since disks are costly.
• The cost of maintenance is high because it requires dedicated employee to maintain and manage it.

Q3

Make sure to use safe and strong passwords to ensure that they don't get hacked.

Q4

a)   Scareware

is a cybercrime scam in which cybercriminals trick a user into buying fake antivirus software by gaining access to your credit card information, and often your computer itself.

b)   Spyware

is a software that installs itself on your computer and starts  monitoring your online behavior without your  permission and also start stealing your the online data and other sensitive information.

c)   Worm

It is a malicious computer program that replicates itself in order to spread to other computers and mostly uses the computer network as a roadmap.

d)   Virus

Is a malicious computer program that is designed to spread from device to device with the aim of damaging a device or stealing valuable data.

e)   Ransonware

It is a malicious software hackers use to restrict you from accessing your own data and encrypting the files on your system to ensure you comply with there demands before they decrypt your system 

f)    DoS

A Denial-of-Service is an attack that is purposely meant to shut down a machine, network from accessing its resources there by making it inaccessible to its intended users to use the system.

g)   SEO Poisoning

It is an attack technique that leads to the creation of web pages full of trending keywords in an effort to trick search engines to get a higher ranking in search results.

h)   Blended Attack

It is an attack that tries to infiltrate a system using multiple attack options and may use an infected machine to launch attacks against other systems.

i)     Exploit

is a part of a program code that takes advantage of a software vulnerability which may be used to channel an attack.

Q5

• Install and use firewall to protect against malicioys traffics.
• Install an Antivirus to ensure that you are protected against viruses.
• Use of strong passwords to protect private data and unauthorised information access
