Computer security

Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures.

The field is of growing importance due to the increasing reliance on computer systems in most societies. Computer systems now include a very wide variety of "smart" devices, including smartphones, televisions and tiny devices as part of the Internet of Things – and networks include not only the Internet and private data networks, but also Bluetooth, Wi-Fi and other wireless networks.

Vulnerabilities and attacks

A vulnerability is a system susceptibility or flaw, and many vulnerabilities are documented in the Common Vulnerabilities and Exposures (CVE) database and vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities as they are discovered. An exploitable vulnerability is one for which at least one working attack or "exploit" exists.

Security (disambiguation)

Security convergence

Security convergence refers to the convergence of two historically distinct security functions – physical security and information security – within enterprises; both are integral parts of any coherent risk management program.

Security convergence is motivated by the recognition that corporate assets are increasingly information-based. Whereas in the past physical assets demanded the bulk of protection efforts, today information assets demand equal (if not far more) attention.

Convergence is endorsed by the three leading international organizations for security professionals – ASIS, ISACA and ISSA – which together co-founded the Alliance for Enterprise Security Risk Management to, in part, promote it.

Yoga

Yoga (/ˈjoʊɡə/;Sanskrit, Listen) is a physical, mental, and spiritual practice or discipline which originated in India. There is a broad variety of schools, practices, and goals in Hinduism, Buddhism and Jainism. Among the most well-known types of yoga are Hatha yoga and Rāja yoga.

The origins of yoga have been speculated to date back to pre-Vedic Indian traditions, is mentioned in the Rigveda, but most likely developed around the sixth and fifth centuries BCE, in ancient India's ascetic and śramaṇa movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads and Buddhist Pāli Canon, probably of third century BCE or later. The Yoga Sutras of Patanjali date from the first half of the 1st millennium CE, but only gained prominence in the West in the 20th century. Hatha yoga texts emerged around the 11th century with origins in tantra.

Yoga gurus from India later introduced yoga to the west, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. Yoga in Indian traditions, however, is more than physical exercise, it has a meditative and spiritual core. One of the six major orthodox schools of Hinduism is also called Yoga, which has its own epistemology and metaphysics, and is closely related to Hindu Samkhya philosophy.

Yoga (philosophy)

Yoga philosophy is one of the six major orthodox schools of Hinduism. Ancient, medieval and most modern literature often refers to Yoga school of Hinduism simply as Yoga. It is closely related to the Samkhya school of Hinduism. Yoga school's systematic studies to better oneself physically, mentally and spiritually has influenced all other schools of Indian philosophies. The Yoga Sutras of Patanjali is a key text of the Yoga school of Hinduism.

The epistemology of Yoga school of Hinduism, like Sāmkhya school, relies on three of six Pramanas, as the means of gaining reliable knowledge. These included Pratyakṣa (perception), Anumāṇa (inference) and Sabda (Āptavacana, word/testimony of reliable sources). The metaphysics of Yoga is built on the same dualist foundation as the Samkhya school. The universe is conceptualized as of two realities in Samhkya-Yoga schools: Puruṣa (consciousness) and prakriti (matter). Jiva (a living being) is considered as a state in which puruṣa is bonded to prakriti in some form, in various permutations and combinations of various elements, senses, feelings, activity and mind. During the state of imbalance or ignorance, one of more constituents overwhelm the others, creating a form of bondage. The end of this bondage is called liberation, or moksha by both Yoga and Samkhya school of Hinduism. The ethical theory of Yoga school is based on Yamas and Niyama, as well as elements of the Guṇa theory of Samkhya.
