3. INTRODUCTION
• We are going to see the types of Cyber security and Cyber
Threads.
• Then there will be some tips to protect our digital
informations with Cyber Security.
• The topic will be continued with the Goals of Cyber Security
and the steps to maintain it.
• There will be the Advantage as well as the Disadvantage of
Cyber Security.

4. WHAT IS CYBER SECURITY?
• 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.
• Cyber Security is the most important sector of this digital world.

5. TYPES OF CYBER SECURITY:
• Network Security: -securing a computer network from
intruders.
• Application Security: - focuses on keeping software and devices
free of threats.
• Information Security: - protects the integrity and privacy of data.
• Operational Security: - includes the processes and decisions for
handling and protecting data assets

6. TYPES OF CYBER THREADS:
• Malware: -it is a malicious software to disturb or damage the legitimate
user’s computer.
• SQL injection: -exploit vulnerabilities in data-driven applications to insert
malicious code.
• Phishing: -cyber criminals target victims with emails that appear to be from a
legitimate company asking for sensitive informations.
• Man-in-the-middle-attack: -cybercriminal intercepts communication
between two individuals in order to steal data.
• Denial-of-service attack: - prevent a computer system from fulfilling
legitimate requests by overwhelming the
networks and servers with traffic.

7. CYBER SAFETY TIPS:
• Update your software and operating system
• Use anti-virus software
• Use strong passwords
• Do not open email attachments from unknown senders
• Do not click on links in emails from unknown senders or unfamiliar
websites
• Avoid using unsecure WiFi networks in public places

8. GOALS OF CYBER SECURITY:
• Confidentiality : -Making guaranteed that your complex statistics is reachable to
accredited users and safeguarding no informations is revealed to
unintended ones.
• Integrity: -Make sure all your data is precise; dependable and it must not be
changed in the show from one fact to another
• Availability: -Every time the operator has demanded a resource for a portion of
statistics there shall not be any bout notices like as Denial of Service
(DoS).

9. ADVANTAGES OF CYBER SECURITY:
• Protects developed systems from hacking.
• Provides privacy of data to end users.
• Protects data from theft.
• Protects systems from viruses,worms and programs that may be unwanted.
• Provides security to networks and resources.
• Protects company data and information .

10. DISADVANTAGES OF CYBER SECURITY:
• Firewalls can be difficult to configure correctly.
• Incorrectly configured firewalls may block users from performing certain actions on the
Internet, until the firewall configured correctly.
• Makes the system slower than before.
• Need to keep updating the new software in order to keep security up to date.

11. CONCLUSION:
•The upcoming of cybersecurity will in one
intelligence be like the current: hard to describe
and potentially limitless as digital skills interact
with humanoid across essentially all features of
policies, society, the family, and outside.
