Institute of Cyber Security of IUP

3. IT Applications & Opportunities
You may have already applied IT in your business:
well developed information system, IT facilities, etc.
You plan to expand your business?
Process an increased amount of data?
Save costs from hiring additional IT staff?
Concerned about upgrading your system?

4. Save Your Data in Clouds
Cloud Services:
Excellent for data storage !
A lot of benefits:
Usability & accessibility
Disaster recovery
Cost saving
Easy sharing
Scalability

5. IT Applications & Opportunities
SOHO Networks (Small Office/Home Office Networks)

6. Beyond Traditional IT Applications
Smart home/smart building,
IoT,
wireless sensor networks, etc.

7. Security Challenges Facing security threats against: Confidentiality
Integrity
Availability

8. Confidentiality for Data in Clouds
Before being sent to the cloud, data may be encrypted using secure encryption algorithms (ciphers)
AES (advanced encryption standard)
Many other available ciphers
You may choose the best one for your business
You may have a huge amount of data
Data are at different levels of sensitivity
Your may have data for different users
Users are in different roles
With different access rights
Need many keys for data encryption !

Question:
How do you manage the keys?
Need to store them properly,
Maintain the secrecy of keys
Require an efficient and secure key management scheme !

11. Wireless Attacks Rogue AP / Evil twin Many other attacks:
Behind a firewall (set up by an insider) / mimic an authorized AP
Many other attacks:
Replay attack
RF jamming

12. IoT Security
Devices and sensors may be deployed in outdoor or even hostile environments – no physical protection !
While we enjoy the IoT applications, cyber-physical systems, wireless sensor networks, how do we ensure the security?
The devices may not afford the existing security procedures – not enough capabilities !

13. IoT Security
Devices and sensors may be deployed in outdoor or even hostile environments – no physical protection !
Require efficient (lightweight) security mechanisms !
The devices may not afford the existing security procedures – not enough capabilities !

14. IoT Security Also, security may be enhanced by running:
anomaly detection
for IoT applications

15. Security: Educational Solutions
However, technical mechanisms alone do not completely solve the security issues
Educational Programs help

16. Cyber security programs of IUP
IUP has been providing cyber security education for almost two decades
We are designated by the DHS/NSA as National Center of Academic Excellence in Cyber Defense Education

17. Cyber security programs of IUP
Department of Mathematical & Computer Sciences
Computer Science, B.A.
Computer Science, B.S., with tracks in
Software Engineering
Cyber Security
Language and Systems
Currently offers two Master’s degrees, and is developing a new program:
M.S. in Computer Science with emphasis in Cyber Security

18. About the Department Department Chair: Dr. Francisco Alarcón
