Security refers to the situation of being protected against a danger. It can be similar to safety. The only difference is the importance given to the element of protection from any potential threats. 

In defining Security we must consider the degree of vulnerability that one is exposed to and take steps to ensure that this does not create any hostile situation.

There are various categories of security. This is an ever-increasing list as the dangers in today’s world are increasing manifold and are taking various forms. We could identify security in the Technology sector which pertains to securing the application, network, data, information etc. Next in the public security sector we could identify airport security, food security, home security and physical security.

There is also the underlying risk of attack or intrusions from any outsider. To keep these at bay and to ensure human safety, countries have adopted national and international security measures. These are mainly collective security measures aimed to secure the people and thereby the country. 

With the growing need to secure people and their interests, there are various companies which provide security consultancy. They are experts in providing security consultancy solutions and advise.

These patrol officers maintain a high visibility presence to deter illegal operations. They are not required to make any arrests but have the authority to ensure law enforcement.
