Security is the degree of resistance to, or protection from, harm. It applies to any vulnerable and valuable asset, such as a person, dwelling, community, item, nation, or organization.
As noted by the Institute for Security and Open Methodologies (ISECOM) in the OSSTMM 3, security provides "a form of protection where a separation is created between the assets and the threat." These separations are generically called "controls," and sometimes include changes to the asset or the threat.
Security has two dialogues. Negative dialogue is about danger, risk, threat and etc. Positive dialogue is about opportunities, Interests, profits and etc. Negative dialogue needs military equipment, armies, police. Positive dialogue needs social capital, Education, social interaction.
Perceived security compared to real security
Perception of security may be poorly mapped to measureable objective security. For example, the fear of earthquakes has been reported to be more common than the fear of slipping on the bathroom floor although the latter kills many more people than the former. Similarly, the perceived effectiveness of security measures is sometimes different from the actual security provided by those measures. The presence of security protections may even be taken for security itself. For example, two computer security programs could be interfering with each other and even cancelling each other's effect, while the owner believes s/he is getting double the protection.
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.

Trustee (or the holding of a trusteeship) is a legal term which, in its broadest sense, can refer to any person who holds property, authority, or a position of trust or responsibility for the benefit of another, also a trustee can be a person who is allowed to do certain tasks but not able to gain income. Although the strictest sense of the term is the holder of property on behalf of a beneficiary, the more expansive sense encompasses persons who serve, for example, on the Board of Trustees for an institution that operates for the benefit of the general public, or a person in the local government.
A trust can be set up either to benefit particular persons, or for any charitable purposes (but not generally for non-charitable purposes): typical examples are a will trust for the testator's children and family, a pension trust (to confer benefits on employees and their families) and a charitable trust. In all cases, the trustee may be a person or company, whether or not they are a prospective beneficiary.
Trustee is a legal term for a holder of property on behalf of a beneficiary.
