What is privacy in an information security context? How has this changed over the years? Moreover what is the difference between our physical privacy and digital privacy? And which one are we most concerned with in our current definition of information security?

What must an attacker do for a sniffer attack to succeed? What protocols are vulnerable to such attacks? What countermeasures should you place on your networked infrastructure to mitigate such attacks? How can an attacker gain access to a secure network to use a sniffer system?

Explain why this phrase is true: Physical access negates all previously applied counter measures.
