Explanation:
In this code, when we create the class object, that is "stu1, stu2, and stu3" and call the parameterized constructor bypassing the "string and integer" value and print the object value you forget to call the "tostring" method because it is the only method which returns both "string and integer" value.

Explanation:
Network Access Control is needed to make sure that only set of verified users access the network.
It makes sure that the users are authenticated and only set of some verified users have access to network.
Set of NAC solutions like Impulse SafeConnect, Extreme Networks, ExtremeControl, Auconet BICS, ForeScout CounterACT, Pulse Policy Secure could be installed in the system which along with basic profiling will make sure authenticated access to the network.
Other than this basic encryption-decryption algorithm can be used in this regard. Network components could use encryption algorithms like RSA and DES. These algorithms will make sure that the information from database side is well encrypted. Once that information goes to the network component. They can decrypt the encryption by generating relevant key using the same algorithm.
This will only allow authentic users to access information and also it will stop the leakage of information in between the transmission because of encryption.
