A safe or vault is an installation that aims to guarantee the security of what it contains.
The term security has multiple uses. Broadly speaking, it can be stated that this concept, which comes from the Latin securitas , focuses on the characteristic of insurance , that is, it enhances the ownership of something where dangers, damages or risks are not recorded . A sure thing is something firm, certain and indubitable . Security, therefore, can be considered a certainty .
There are many types of security, as many as there are activities that human beings can perform. In this article we will cite only some concepts in which the term is used in reference to the safe development of a certain activity.
Food security and legal security
The so-called food security emphasizes the availability and access to food products in both quantity and quality. This food security is only achieved when all individuals have safe and nutritious food available at all times to satisfy their nutritional requirements.
Legal certainty is valued as a principle that is framed in the field of law and that is associated on a global scale with the certainty of knowing what is foreseen as prohibited with respect to one in relation to the rest and from them to the same individual.
The concept linked to automobiles
In motorsports, we speak of the safety car or safety car to refer to the vehicle whose function is to neutralize the race, with the aim of grouping the participants in the event of a serious accident or due to meteorological causes.
On the other hand, the seat belt is a harness designed to restrain the occupant of a vehicle in the event of a collision. It is considered to be the most effective passive safety system that exists today.
Occupational safety is linked to the protection of the integrity of workers.
Job security
The term job security has to do with the conditions under which employees work.
According to the law of each State , there are a series of requirements that employers must meet in order to offer stability, balance and prevention to their employees, so that no accident that occurs at work can end in a tragedy.
The notion in computing
One of the meanings of the term is that used in computing , a modern but extremely important concept to keep computers and related equipment in good condition. Computer security makes it possible to ensure that system resources are used in the manner expected and that those who can access the information contained therein are the people authorized to do so.
In computing, there are two types of security: physical (physical barriers that prevent any non-accredited person from entering the system. It is carried out through specific applications and procedures that aim to block access to said individuals ) and logic (the ways in which this type of security is performed is through code encryption, so that they cannot be read or translated by intruders who could overcome physical barriers, authentication and antivirus codes or fire wall , in the case of using an operating system such as Windows). When developing a design, whether for a web page or a space on the network, taking both types of security into account is essential.
Hackers, crackers and security
It is worth clarifying that in computer security there are certain concepts that it is necessary to know and that have to do with it, these are: hacker and cracker .
A hacker is an individual who is always looking for a way to violate the security barriers of information systems in order to obtain some type of confidential information. The fundamental objective of the true hacker is to learn and satisfy their curiosity and creativity , they do not seek to do harm. His desire is to create, not destroy. He is a true geek (someone obsessed and in love with technology in general and computing in particular).
A cracker is someone who has capabilities similar to those of a hacker but uses them for malicious purposes . The reason for all their research is to destroy systems , delete or steal data, and do harm just for fun.
The defense of the nation
Finally, it should be noted that security can refer to national defense . These are the policies that each State designs in order to prevent or confront possible military operations promoted by other countries . National security is usually linked to the armed forces and weapons .
Having said all this, it only remains to add that in any area when talking about safety we are referring to the conditions in which an activity is carried out: the preventions that have been taken into account in case of complications, the actions that will be carried out in case of disaster and fundamentally, how work will be done to provide balance and tranquility in said environment.
