What is Cyber Security?
Types of cyber threats
Cybercrime include
s single actors or
groups targeting
systems for financial
gain or to cause
disruption.
Cyber-attack often
involves politically
motivated
information
gathering
Cyberterrorism is
intended to
undermine
electronic systems
to cause panic or
fear.
 Cyber security is the practice of defending computers, servers, mobile
devices, electronic systems, networks, and data from malicious attacks. It's
also known as information technology security or electronic information
security.

What is Digital Forensics Sciences?
 Digital forensics is a branch of
forensic science that involves
the use of scientific methods to
identify, acquire, process,
analyze, and report on
electronic data.
 The goal of digital forensics is
to preserve evidence and
establish facts from digital
information to help reconstruct
criminal events, anticipate
disruptive actions, and
determine the root cause of an
incident.

• Digital forensics can help identify criminals, track terrorists, locate missing
people, and bring killers to justice. For example, digital forensics has helped
catch people involved in illegal pornography and employees who were stealing
millions of dollars.
Help solve crimes
• Digital forensics can help protect corporate interests.
Protect corporate interests
• Digital forensics can make a tangible difference in the lives of people around the
world.
Make a difference
• As technology continues to evolve, the importance of digital forensics will only
continue to grow.
Keep up with technology

Roadmap of DSA For
Beginners
• Flowcharts are step-by-
step procedures where a
solution to a problem is
provided in blocks
• pseudocodes are the
informal language used to
express solutions to a
problem.
Flowchart and
Pseudocode
• Before you start learning
DSA, it’s good to choose a
programming language
initially.
• There are many
programming languages
but Java/C++/Python is the
most used for DSA.
Programming
Language
• The main purpose of
learning OOPS is to
understand how the data
and the functions operate.
• The basics of OOPS are:
Encapsulation, Abstraction,
Polymorphism, Inheritance
OOPS
• Time complexity can be
defined by the time taken to
run an algorithm.
• Space complexity is the
amount of memory a
program takes to run it, it
also depends on the input
data.
Complexities
(Time and
Space)
• A data structure is a
method to store and
organize data so that it can
be accessed and updated
efficiently.
• An algorithm refers to a
finite set of rules followed
to solve a problem.
Learn Basics of
Data Structures
& Algorithms
• Try solving at least 5-10
DSA problems daily if
you’re a beginner and if
you’re already well aware
of it, you can solve as
much as you want to.
