Cyber security and data protection are important in the digital era. Cyber security protects information and data from unauthorized access on the internet. It ensures only authorized people can access data. There are various security threats like malware, phishing, and man-in-the-middle attacks that can compromise data. Cyber laws like the IT Act 2000 and its 2008 amendment provide legal framework for electronic transactions and define cyber crimes and penalties. The Data Protection Act 2018 also governs how personal information is collected and used by organizations.

4. Digital Era
Today we are living in digital era
Internet is used today-
 Booking hotels
 Ordering foods
 Booking cabs
Big data is generating today that is stored on cloud on huge data
servers or data centers
Array of devices used to access data stored on cloud.
For Hackers it is golden edge
A lot of access point, IP addresses.

5. Introduction
 Cyber security is the practice of protecting information and data from
outside sources on the Internet. Cyber security professionals provide
protection for networks, servers, intranets and computer systems.
 It also ensures that only authorized people have access to that
information.

6.  Cyber is related to the technology which contains systems, network
and programs or data. Whereas security related to the protection
which includes systems security, network security and application
and information security.

7. Why is cyber security important?
 Cyber security is necessary since it helps in securing data from threats
such as data theft or misuse, also safeguards your system from viruses.
 We all live in a world which is networked together, from internet
banking to government infrastructure, where data is stored on
computers and other devices. A portion of that data can be sensitive
information, whether that be intellectual property, financial data,
personal information, or other types of data for which unauthorized
access or exposure could have negative consequences.

8.  Cyber-attack is now an international concern and has given many
concerns that hacks and other security attacks could endanger the
global economy. Organizations transmit sensitive data across
networks and to other devices in the course of doing businesses,
and cyber security describes to protect that information and the
systems used to process or store it.

9. History
 1969- A professor in UCLA sent a message to standard research
institute.
 1970-Robert Thomson created first virus namely CREEPER
I am CREEPER Catch me if you can
Antivirus for creeper was PREEPER
 1986-Rassian used cyber power as weapons
 1988-American scientestist created program to check size of
internet
 After that we people started working on cyber security.

10. Security Goals(CIA)
 Confidentiality: No unauthorized access
 Integrity: What you sent,
received without alter
 Availability: 24X7 Access availability to authorized user
use encryption
HELLO HELLO

11. Cyber Threats
INTRUDER
Malware
Phishing
Password
Attacks
Man in
Middle
attack
DDOS
Trapdoors
Logic
bombs
Spoof
Macro
Virus

12. Malware
 The word "malware" comes from the term "MALicious softWARE“.
 Code with malicious intends steals data and destroys data from
computer eg. Trojan, Virus, Bombs
 To Stop Malware:
 Download an anti-malware program that also helps prevent
infections.
 Activate Network Threat Protection, Firewall, Antivirus.

13. Virus & Worms
 A piece of software that are designed to spread one computer to another
. Almost all viruses are executable files. A virus can spread using
 Network
 Disk
 File sharing
 Email attachments
 VLC download
Mail
Virus
Attachment

14.  Worms are piece of malware program that replicates and spreads
one computer to another. It spreads to itself to connected computers.
 Solution: Install a security suite that protects the computer against
threats such as viruses and worms.
Mail
WORM
(I LOVE YOU)2K

15. Trojan Horse
 Trojan horses are email viruses that can duplicate themselves, steal
information, or harm the computer system.
 It tricks user to running it behind the trusted program
 These viruses are the most serious threats to computers.
How to Avoid Trojans?
 Security suites, such as Avast Internet Security,
will prevent you from downloading trojan Horses.

16. Phishing
 Phishing attacks are sent in e mail and said by user to click on it

17.  Password attacks are attacks by hackers that are able to determine
passwords or find passwords to different protected electronic areas and
social network sites.
Securing Password:
 Use always Strong password.
 Never use same password for two different sites.
Password Attack

18. DDOS

19. Logic Bombs
Logic bombs attacks on system on specific condition
Eg. Saturday @10 o’clock

20. Trapdoors
Secret entry point in to a program that allows to gain access
system without using security access procedure.
Android – google can enter

21. Spoofing
Spoofing is often the way a bad actor gains access in order to execute a
larger cyber attack . E mail spoofing,Caller id spoof,Website spoof
DNS Spoofing

22. Man in Middle attack

23. Macro virus
Not created in any programming languages

24. Cyber Law
 Cyber Law is the law governing cyber space.
