this ppt is about how attacks are performed how to protect from it

1. PRESENTED BY
PARSHURAM

• Sri indu college of Engineering and technology

3. WHAT IS CYBER SECURITY
• As we know present generation totally depend upon the computer
• And also there is also increase of security for these computers
• Illegal activity to these systems are called as CYBER SECUIRITY
• so how to protect our self from it
• And also there is a proverb that there will be no 100%secuirity to any
systems
• But we can be increase our vulnerability of our systems

4. TYPES OF CYBER ATTACKS
• Brute forcing attacks
• Sql injection
• Social engineering(pishing)
• Dictionary attacks & shoulder surfing
• Virus or worms
• Ransomware
• Man in the middle attack
• Direct denial of service (DDOS) attack
• Email and software forgering

5. HISTORY
• The first recorded cyber crime was recorded in year 1820
• The first spam email took in 1978 when it was sent over Arpanet
• The first virus was installed on a apple computer in 1982

6. DICTIONARY ATTACK
• It is a type of attack in which hacker uses a dictionary to
crack password
• This type of attacks are not so effective
• And also time taken process

7. SHOULDER SURFING
• A tried and true method of
gaining acess
• In this type of attacks
passwords are leaked by
observing our shoulders
• When typing password

8. SNIFFING & PORT SCANNING
SNIFFING
Sniffing a process of capturing and analyzing the traffic in a
network
PORT SCANNING
It is a method to probe a system for open ports
Intruder can exploit the vulnerabilities of open ports

9. VIRUS AND WORMS
• Virus and worms are the programs coded in such a way that the its
take control of whole system
• Its size is 1 kb!!!!!!

10. BRUTE FORCING ATTACK
• It is method of cracking password
same as dictionary attack
• But trying with number and symbols

11. SQL INJECTION

hacking

12. A BRIEF ABOUT SOCIAL ENGINEERING ATTACKS
• In a word I can say that”a lazy click can smash
your career”
• Clever manipulation of natural human tendency
to trust
• Here is example of cloning a website facebook
• Actually its not a original page it’s a
• Pished page

13. RANSOMWARE
• Ran+sum+ware
• Its is type of attck where hacker
gain access and encrypts all data()
and demands money if admin
wants the data back

14. MAN IN THE MIDDLE
• Its atype oh hacking where hackers
capture network flow this is called
as sniffing
• Then acts as a middle man
between server and client and
obtain passwords

15. DDOS(DISTRIBUTED DENIAL OF SERVICE)
• Distributed DoS attack. A
distributed denial-of-
service (DDoS) attack occurs when multiple
systems flood the bandwidth or resources
of a targeted system, usually one or more
web servers.

16. EMAIL SPOOFING AND SOFTWARE
FORGERING
• this is a part of social engineering
attacks
• In these type of attacks email are
forgeries and spammed by malicious
virus and RATS
• Same in the case of software's. When we
install software's the actual software
does not install but other programs get
installed in background

17. PROTECTION FROM THESE
ATTACKS
• Before download in any thing check its
certificate
• Do not open any mails of any anonymous
persons

18. • Improve ips and ids
• Keep different passwords for every account
• Frequently change ur passwords atlest ones for month
