Problem: 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]
What do ACLs promise?

Problem: The Epicureans and the Cynics rejected public offices and civic service, which amounted to a rejection of the polis itself, the defining institution of the Greek world. Epicurus promoted atomism and an asceticism based on freedom from pain as its ultimate goal. Cynics such as Diogenes of Sinope rejected all material possessions and social conventions (nomos) as unnatural and useless. The Cyrenaics meanwhile, embraced hedonism, arguing that pleasure was the only true good. Stoicism, founded by Zeno of Citium, taught that virtue was sufficient for eudaimonia as it would allow one to live in accordance with Nature or Logos. Zeno became extremely popular, the Athenians set up a gold statue of him and Antigonus II Gonatas invited him to the Macedonian court. The philosophical schools of Aristotle (the Peripatetics of the Lyceum) and Plato (Platonism at the Academy) also remained influential. The academy would eventually turn to Academic Skepticism under Arcesilaus until it was rejected by Antiochus of Ascalon (c. 90 BCE) in favor of Neoplatonism. Hellenistic philosophy, had a significant influence on the Greek ruling elite. Examples include Athenian statesman Demetrius of Phaleron, who had studied in the lyceum; the Spartan king Cleomenes III who was a student of the Stoic Sphairos of Borysthenes and Antigonus II who was also a well known Stoic. This can also be said of the Roman upper classes, were Stoicism was dominant, as seen in the Meditations of the Roman emperor Marcus Aurelius and the works of Cicero.

Problem: The foundation trust invests undistributed assets, with the exclusive goal of maximizing the return on investment. As a result, its investments include companies that have been criticized for worsening poverty in the same developing countries where the foundation is attempting to relieve poverty. These include companies that pollute heavily and pharmaceutical companies that do not sell into the developing world. In response to press criticism, the foundation announced in 2007 a review of its investments to assess social responsibility. It subsequently cancelled the review and stood by its policy of investing for maximum return, while using voting rights to influence company practices.
When did the company decide to review its lack of sales in the developing world?
