[9] [10] Interhuman transmission is a synonym for HHT. [ 11 ] The World Health Organization designation of a pandemic hinges on the demonstrable fact that there is sustained HHT in two regions of the world.
Level 2 Security (L2S) EMBEDDED Data—Level 2 Security improves upon the physical security mechanisms of Level 1 Security by taking information protection to a covert and embedded level. This prevents casual intruders from gaining access to, for example, encoded confidential information inside an embedded chip or other means of encoding.
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. [1] It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.
Many secure transmission methods require a type of encryption. The most common email encryption is called PKI. In order to open the encrypted file, an exchange of key is done. Many infrastructures such as banks rely on secure transmission protocols to prevent a catastrophic breach of security.
Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data. [1]
Multiple Independent Levels of Security/Safety (MILS) is a high-assurance security architecture based on the concepts of separation [1] and controlled information flow. It is implemented by separation mechanisms that support both untrusted and trustworthy components; ensuring that the total security solution is non-bypassable, evaluatable, always invoked, and tamperproof.
The emergence of the human security discourse was the product of a convergence of factors at the end of the Cold War.These challenged the dominance of the neorealist paradigm's focus on states, "mutually assured destruction" and military security and briefly enabled a broader concept of security to emerge.
A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy. For a more complete list of available articles on specific security models, see Category ...
