What is Cyber Security
What is Cyber Security
•
Cyber Security is the method of
safeguarding computers, servers, cellular
devices, electronic devices and data from
digital attacks.
•
In other words it is known as information
technology security or electronic
information security.
Cyber Security Elements
•
Network security
•
Application security
•
Information security
•
Operational security
•
Disaster recovery and business continuity
•
End user education
Applications of cyber security
•
E-commerce
•
Online banking
•
Internet of things
•
Smart grid
•
Automotive technology
The scale of cyber threat
•
2019 has seen 7.9 billion data breaches in
the first nine months.
•
112% more than the data breaches in
2018 in the same period
•
Worldwide spending will reach 133.7
billion by 2022
•
3.5 million unfilled jobs by 2021.
Cyber security challenges and issues
Already existing
•
Virus
•
Trojans
•
Spyware
•
Ransomware
•
Adware
•
Botnets
•
SQL Injections
•
Phishing
•
Man-in-the-middle attack
•

Emerging cyber threats
•
Deepfake technology
•
Quantam computing
•
Artificial Intelligence
Methods to combat the cyber security
challenges
•
Artificial Intelligence
•
Blockchain technology.
•
Encryption
Compare AES and DES
•
AES can be of 128 bits,192 bits and 256 bits
wheareas DES key length is 56 bits.
•
DES takes 16 rounds identical operation while
AES involves 10,12,14 rounds depending on the
key length.
•
AES is more secure than DES.
•
DES is vulnerable to brute force,linear crypt-
analysis and differential crypt analysis .
•
On the other hand, there are no known crypt
analytical attack against AES
Suggestions to avoid cyber attacks
•
Update your system to the latest security
patches
•
Use strong anti-virus software
•
Avoid opening email attachments from
unknown senders
•
Do not use unsecure wifi networks in
public places
END OF PRESENTATION
