Question 4 Long Questions
[15 marks]



4.1 Differentiate between a Firewall and Hardware Firewall
(2)



A Firewall – is a software program or hardware device that protects
networks from unauthorized access by blocking unsolicited. Or
Firewalls allow incoming or outgoing traffic that has specifically
been permitted by configuring settings. And or Firewalls use complex
filtering algorithms that analyze incoming network data based on
destination and source addresses, port numbers, and data type.



A Hardware Firewalls – is a hardware device, either stand-alone or
built into most routers, that protects computers on a private network
from unauthorized traffic.




4.2 Explain what is an encryption.
(1)



Encryption – is the process of converting data into a form that is not
easily recognized or understood by anyone who is not authorized to access
the data. Or Encryption – can be one-way, which means the encryption is
designed to hide only the cleartext and is never decrypted, or it can be
two-way, in which the encryption can be decrypted back to cleartext and
read.



4.3 Wireless encryption conceals and protects data during transmission so
that if the

data were accessed during transmission it cannot . Mention Three
encryption types

available to provide encryption over wireless data transmissions.
(3)



Wired Equivalent Privacy (WEP)

WiFi Protected Access (WAP)

WPA2 or 802.11i



4.4 Describe in detail Social engineering attack.
(2)



Social engineering attack – is type of attack that uses deception and
trickery to convince unsuspecting users to provide sensitive data or to
violate security guidelines.



4.5 Mention eight various types of social engineering attacks.
(8)



Shoulder surfing

Spoofing

Impersonation

Hoax

Phishing

Vishing

Whaling

Spam and spim
