2. Introduction
● What is Cybersecurity?
○ Protecting computers
○ Access authorization
○ Relevance to IS
● History
○ Creeper and Reaper
○ First dedicated antivirus company in 1987
○ Morris worm in 1989
● Why Cybersecurity
○ Personal information at stake
○ Affects companies, governments, individuals
○ Lower risk in Cyber crimes

3. The CIA Triad
● Confidentiality
○ Preventing unauthorized disclosure of
information
● Integrity
○ Validating that your data is trustworthy
and accurate
● Availability
○ Ensuring data is readily available for
authorized users

4. Cyber Threats
● DDoS (Distributed Denial of Service)
● Backdoor
● Social Engineering

5. Cyber Threats
● Malware
● Evil Maid
● Eavesdropping

6. CIA violations in Real World
• WannaCry Ransomware
o Backdoor – Availability
Encrypted data and hackers demanded for ransom
• Facebook/Google Privacy
o Social Engineering – Confidentiality & Integrity
Facebook let personal information of 87 million users
exposed to British Analytics firm to supposedly
disinform users and affect US presidential elections
• GitHub
o DDos – Availability
Hit with most powerful DDos attack ever recorded of
1.35 terabytes per second. Github having a good
cybersecurity system in place recovered in 10 minutes
• Dark Web
o Social Engineering - Confidentiality & Integrity
Since data is not indexed or encrypted, information
flow is potentially vulnerable throughout the Dark
Web

7. Preventive measures
● Hackers are persistent
● Key to staying ahead is staying
informed
● Various measures must be taken,
both by Enterprises and Individuals

8. Enterprise level
● Identify the Threats
● Educate Employees about potential
threats
● Implement Two-Factor
Authentication
● Ensure a Strong Sign-Off Policy
● Insure the Company Against
Cybercrime

9. Individual level
● Responsibly dispose your electronic
devices
● Maintain backups of your data
● Regularly update your antivirus
system
● Use Two/Multi-Factor Authentication
● Use encryption
● Password Management
● Discern the types WiFi networks
● Report cyber scams to FBI’s Internet
Crime Complaint Center or the
Federal Trade Commission

10. ● 2017 – 8 billion connected devices to the internet
● 2023 – 45 billion IoT devices are expected to go online
● As the IoT continually evolves and grows, the number of cyberattacks increases.
● IoT attacks has increased from about 6,000 to 50,000 in the span of one year (2016 –
2017). Rise of 600%.
● Strategies used for IoT attacks:
-Identity compromise
-Device vulnerability
-Unprotected patches and upgrades
-Man-in-the-middle
Future – Cybersecurity with IoT

11. Strategies for protecting IoT
•Because IoT is a hyper-connected, and
hyper-distributed collection of resources,
there are many behaviors that need to
be monitored to keep connected IoT
devices in check.
