Dear Ankita Jiyani,

as a very broad current topic for your PhD can be:

„Analysis of Security in SDN-enabled Cloud Computing Environments“

See these sources of literature on this topic.

Best regards and much success

Anatol Badach

Hi.,

If you are interested,try to follow:

• Automated service provisioning.
• Virtual machine migration.
• Server consolidation.
• Energy management.
• Traffic management and analysis.
• Data security.
• Storage technologies and data management.
• Software frameworks.

Hello,

You can work on software defined networks or zero client and thin client based networks for your PhD dissertation.

Dear Anatol Badach,

Can you please describe the research problem further. As it is a new area, and a lot can be done in this field. The primary focus in the literature was the DoS/DDoS attacks on the SDN network.

For e.g. 1. DDoS attacks can be mitigated using fuzzy logic can be the research area.

2. encryption of virtual machine, or resources, as it can be accessed by any third party.

3. There is a research scope for securing the SDN controller, as it is the brain of the network.

Please give your valuable suggestions.
