Ko’p sathli xavfsizlik modellari Ushbu bo’limda ko’p sathli xavfsizlik sohasida xavfsizlik modellarini qarab chiqamiz. Xavfsizlik modellari odatda xavfsizlik oid darsliklarda katta hajmda tushuntiriladi. Ammo, bu yerda biz ikkita aniq xavfsizlik modeliga to’xtalib o’tamiz. Umuman olganda xavfsizlik modellari tavsif bo’lib, taqiqlanadigan narsa emas. Ya’ni mazkur modellar himoyalanish uchun nima kerakligini aytadi. Biroq ular haqiqiy savolga javob bermaydi, ya’ni, bunday himoyani qanday ta’minlash kerakligini aytmaydi. Bu modellarning kamchiligi emas, sababi ular himoya uchun asos yaratishga mo’ljallangan. Biroq, bu xavfsizlik modellashtirishining amaliy yordamiga xos bo’lgan cheklovdir.
Birinchi ko’rib o’tiluvchi xavfsizlik modeli Bell-Lapadula (Bell-LaPadula, BLP) bo’lib, bu nomlanish uning yaratuvchilari Bell va Lapadula nomlariga berilgan. BLPning asosiy maqsadi har qanday MLS tizimini qanoatlantirishi kerak bo’lgan konfidensiallikka nisbatan minimal talablarni to’plashdir. BLP quyidagi ikki formulirovkadan tashkil topgan: Xavfsizlikni oddiy sharti: agar faqat va faqat shart bajarilganda subyekt obyektni o’qishi mumkin. *-Xususiyat (erkinlikni cheklash): faqat va faqat shartda subyekt obyekt ga yozishi mumkin.
