3. Mobile Computing
21-11-20183
 Mobile devices are
connected through
Wireless Networks.
 Major concern –
Security
 Necessary to have
robust security and
secure infrastructure.

4. What to secure in Mobile
Devices?

5. Attacks
21-11-20185
 Attacks are carried
out on the point of
vulnerability.
 Attack on Static Data-
Virus deleting files or
jamming device
 Attack on Dynamic
Data- Credit card
number theft while
transaction.

6. Attack on Static Data
21-11-20186
 Virus: These are the type of programs that
propagates from one computer to another.

7. Attack on Static Data (cont’d…)
21-11-20187
 Denial of Service:

8. Attack on Static Data (cont’d…)
21-11-20188
 Intrusion: These are people or software, which
enter into systems and perform functions without
the knowledge of the owner.

9. Attack on Dynamic Data
21-11-20189
 Interception:

10. Attack on Dynamic Data
(cont’d…)
21-11-201810
 Interruption:

11. Attack on Dynamic Data
(cont’d…)
21-11-201811
 Modification:

12. Attack on Dynamic Data
(cont’d…)
21-11-201812
 Fabrication

13. The attacker needs “MOM”!
21-11-201813
 Method: the skills, knowledge, and tools with
which to be able to pull off the attack
 Opportunity: the time and access to accomplish
the attack
 Motive: a reason to want to perform this attack
against a particular system

14. Components of Security
(cont’d…)
21-11-201814

15. Components of Security
(cont’d…)
21-11-201815
 Confidentiality: It is a property where information
is kept secret from the unauthorized users.
How to ensure Confidentiality?
Encryption
Authorization

16. Components of Security
(cont’d…)
21-11-201816
 Integrity
Keeping the information intact.
maintaining the consistency, accuracy, and
trustworthiness of data over its entire life cycle
How to ensure Integrity?
Checksums
Digital signatures

17. Components of Security
(cont’d…)
21-11-201817
 Availability
Refers that the system should be available always
to the legitimate users.

20. Techniques for ensuring Security
21-11-201820
 Encryption
Maintains the confidentiality of data
Idea: Scramble the data so that they become
unreadable to the attacker.

21. Techniques for ensuring Security
(cont’d..)
21-11-201821
 Types of Encryption
Symmetric Encryption
Asymmetric Encryption

23. Techniques for ensuring Security
(cont’d..)
21-11-201823
 Public key Cryptography
 For Encryption/Decryption

24. 21-11-201824
 Public key Cryptography cont’d..
 For Authentication

25. Security Protocols
21-11-201825
 SSL (Presentation Layer) – Security of data over
public networks like internet. (HTTPs)
 TLS (Transport Layer) - Provide privacy and data
integrity between two communications
 WTLS(Transport Layer) – Provide interface for
creating and terminating secure connections.

Environment
21-11-201827
 3GPP Security
 Mobile Virtual Private Network
 Multifactor Security
 Smart Card Security
 Mobile Virus
