Blocking Communication on the Same Network Unless Specified

Hi, I just have a quick question surrounding communication on within the same network. 

 

I know that between different networks I have to define rules to allow communication e.g. if i want to RDP between VLAN 101 (10.10.1.1) and 102 (10.10.2.1) which are separate networks I will have to define the rule

10.10.1.1 (network) -> RDP -> 10.10.1.2 (network) 

But what if i wanted to apply the same policy when communicating within the same network? e.g. currently when using RDP from a PC on 10.10.1.1 to connect to another PC on 10.10.1.1 there is no need to define any rules for this communication, it seems that same-LAN communication is allowed by default. 

How will i achieve the effect of 'block unless specified' for communications within the same network?
