In my Jira project I need to create two different groups and restrict their view as per component.

In my project I have Funtional groups field. In this field we have around 15 options. Based on this functional group, I want to restrict the issues which a particular group can view. 

I will explain this with an example.

Suppose I have functional groups as a, b, c and d. I need to create a group who can view only issues related to functional group 'a', remaining issues this group should not be able to view.

Another group should be able to view only functional group 'b' and 'c' related issues.

How can I apply this filter or security in my Jira project?

This can be achieved by Group Custom Field Value option in Issue security. 

For this you should use group picker field . create a group picker field  and select the respective group (A,B,C..etc). In the security,  you can select Group Custom Field Value option and choose the group picker field . so the respective group members only can view the ticket.
