Problem:

Question 1: What is privacy in an information security context?how has this changed over the years? moreover whats the difference between our physical privacy and digital privacy ?and which one are we most concerned with in our current definitiono of information security?

Question 2: What must an attacker do for a sniffer attack to succeed?what protocols are vulnerable to such attacks what counter measures should you place on your networked infrastructure to mitigate such attacks?how can an attacker gain access to secure network to use a sniffer system?

Question 3: Explain why this phase is true:physical access negates all previously appliedcounter measures.

Could someone help to explain the answer of these questions.
