Many believe that complete security is infeasible. Therefore, we are left with incomplete security. Generally, the greater the security, the greater the cost. Discuss how one should weigh the benefits and associated costs of security.

Answer:

I Agree that Complete security is infeasible , as there will always be some percentage of security left to be completed. Security basically refers to defend the internet attacks or viruses which are being attacked to your system increasing the risk of leaking out your sensitive data.Internet security requires a protective firewall depending on your requirement . Following are the types of security and privacy to the data

• Access control.
• Anti-keyloggers.
• Anti-malware.
• Anti-spyware.
• Anti-subversion software.
• Anti-tamper software.
• Antivirus software.

In this case the cost is totally dependent on the network you are relying on and the data sensitivity. if data contains personal details of an individual which is very sensitive the cost on security has to be raised in investing better firewall policies . similarly if the data isnt sensitive one can get firewall policies with basic level policies.
