Answer:

The answer is False.

Explanation:

By definition LIFO structure is defined by: Last In, First Out.

By definition FIFO structure is defined by: First In, First Out.

A queue has the basics operations push() and pop() where:

push(element) stores the element at the end of the queue.
element = pop() retrieves the element at the beginning of the queue.

For example:

If you insert the elements doing the push(e) and q.pop(e) operation:

Queue q;

Element e;

q.push(2); // q ={2};

q.push(5); // q ={2 , 5};

q.push(6); // q = {2, 5, 6};

q.pop(e); // q ={5, 6}; e = 2;

q.push(12); q ={5, 6, 12};

q.pop(e); // q ={6, 12}; e = 5;

Note: A stack is a LIFO structure.

What is the first step in devising security services and mechanisms?

N76 [4]

Solution:

The first step in devising security services and mechanisms is to develop a security policy.

A security policy is a document that states in writing how a company plans to protect the company's physical and information technology (IT) assets. A security policy is often considered to be a "living document", meaning that the document is never finished, but is continuously updated as technology and employee requirements change. A company's security policy may include an acceptable use policy, a description of how the company plans to educate its employees about protecting the company's assets, an explanation of how security measurements will be carried out and enforced, and a procedure for evaluating the effectiveness of the security policy to ensure that necessary corrections will be made.

This is the required answer.
