There are porous areas in the border due to terrain and also constant firing from pakistani areas when such areas are attempted to be fenced.
Some areas in the border and LOC remain easy to breach due to terrain, inadequate fencing, lack of electronic monitoring and lack of patrol frequency. So yes there is a big blame on the Indian side to not take adequate measure to protect the LOC/ IB.
As far as education on type of security cordon, it would be violation of security protocols to provide any related data which is susceptible to breach by the "Non State Actors", so neither will the GoI or any sane minded Indian would educate anyone type of countermeasures in the terrorism affected areas.
As far as base attacks are involved they are often breached exactly as PAF Minhas Base or PN'S Mehran Base, or Camp Bastion attack have been perpetrated. It shouldn't be a surprise that larger sized bases always have vulnerabilities that are associated with it's location, terrain, and security protocols.
may i direct a counter question to you, where do the "Kashmiri Mujhahideen" get their sat phones, rations, type 56's, AKM's, RPK's, chinese clone Pso 1 scopes, 7.62x 39 ammunition, PoF marked hand grenades from?
