Question

The fundamentals of firewall and its basics can be described by the following, except one? Justify your choice?

1. Like a sentry at the border or a gateway, a firewall watches for traffic that fails to comply with the rules or filters defined by a firewall administrator.
2. There is still a disagreement among network administrators as to whether firewall is a key component of infrastructure security or a hinderance to essential network security tasks.  
3. Default-deny or default-allow are the two main philosophies or security stances that govern the use of rules, where a default-deny stance assumes that all traffics are potentially malicious, at least unwanted, or unauthorized, and a default-allow stance assumes that most traffics are benign.
4. It is inaccurate or an overstatement to say that every network needs a firewall, at home, work, school, or otherwise because firewall is not fundamental to network communications.

Answer 1

Correct choice : (There is still a disagreement among network administrators as to whether firewall is a key component of infrastructure security or a hinderance to essential network security tasks.)

Explanation - Network administrators always are on the side of considering firewall as a key security. Every system including from a single home PC to a complex network linked systems should have firewall installed. It doesn't matter weather a system is installed with great internet security tool or not but a firewall is necessary. The only restriction with firewall is that it can't be able to save the system from inside existing resources such as virus coming from hard- disk etc.
