Article: Within computer systems, two of many security models capable of enforcing privilege separation are access control lists (ACLs) and capability-based security. Using ACLs to confine programs has been proven to be insecure in many situations, such as if the host computer can be tricked into indirectly allowing restricted file access, an issue known as the confused deputy problem. It has also been shown that the promise of ACLs of giving access to an object to only one person can never be guaranteed in practice. Both of these problems are resolved by capabilities. This does not mean practical flaws exist in all ACL-based systems, but only that the designers of certain utilities must take responsibility to ensure that they do not introduce flaws.[citation needed]

Question: A host computer tricked into indirectly allowing access to restricted files is known as what?
Ans: the confused deputy problem

Article: This influx was compounded by the decline of the Western Sudanic Mali Empire in 1375 and the Songhai Empire in 1591. Additionally, as inland regions underwent desertification, inhabitants moved to the wetter coast. These new inhabitants brought skills such as cotton spinning, cloth weaving, iron smelting, rice and sorghum cultivation, and social and political institutions from the Mali and Songhai empires. Shortly after the Mane conquered the region, the Vai people of the former Mali Empire immigrated into the Grand Cape Mount region. The ethnic Kru opposed the influx of Vai, forming an alliance with the Mane to stop further influx of Vai.[citation needed]

Question: What happened when regions underwent desertification?
Ans: inhabitants moved to the wetter coast


Article: The term "Late Middle Ages" refers to one of the three periods of the Middle Ages, along with the Early Middle Ages and the High Middle Ages. Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (1439–1453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).

Question: Along with the Late Middle Ages, what are the other two period of the Middle Ages?
Ans:
Early Middle Ages and the High Middle Ages
