Question 5 Define the terms symmetric and
asymmetric encryption. Answer Symmetric
Encryption The same key is used for both
encryption and decryption in symmetric
encryption. When it comes to symmetric, the
process moves at a faster rate. Asymmetric
Encryption Different keys are used for the two
processes in asymmetric encryption. This method
of encryption is difficult and time-consuming. Qu
estion 6 Define the terms white hat and black
hat hacker. Answer White hat and Black hat
hackers are two synonymous terms. Both groups are
knowledgeable at breaking into networks and
gaining access to otherwise secured data. White
Hat Hacker These are referred to as ethical

commonly use them to identify flaws. Black Hat
Hacker The creation of malware is the
responsibility of Black hat hackers. They gain
unauthorized access to data or networks, causing

Question 7 Define the salting process and its
application. Answer Salting adds special
characters to a password to make it more secure.
This strengthens the passcodes in two ways it
makes it longer and helps to add another set of
characters from which a hacker would have to
guess. Its a reasonable precaution to take for
users who have a habit of creating weak
passwords. Still, its a low-level defense
because many highly experienced hackers are
already familiar with the process and consider
it. Question 8 What are your strategies for
dealing with Man-In-The-Middle
attacks? Answer A Man-in-the-Middle attack
occurs when a third party monitors and controls
communication between the two parties while the
latter is utterly unaware of the situation. There
are two approaches to dealing with this
attack. 1.Stay away from open Wi-Fi
networks 2.Both parties should use end-to-end
encryption

Question 9 Which is the more secure option,
HTTPS or SSL? Answer HTTPS (Hypertext Transfer
Protocol Secure) combines HTTP and SSL (Secure
Sockets Layer) to encrypt and secure a users
browsing activity. SSL (Secure Sockets Layer) is
a data encryption protocol that encrypts data
sent over the internet among two or more
entities. Though this is close, SSL comes out on
top in terms of overall security, though any of
these are useful to know for web
development. Question 10 What does AAA stand
for? Answer AAA is an acronym for
Authentication, Authorization, and
Accounting. Authentication The procedure of
determining whether a user is authorized to use
the system and network is known as
authentication. Login and password are commonly
used for authentication. Authorization Access
control rights are referred to as authorization.
This means that, depending on the position in the
organization, each user on the network has access
to different portions of data, information, and
applications. Accounting Network accounting is
a type of accounting that collects all network
activity for each user.
