Expert Solution & Answer
Chapter 4.8, Problem 4SGDQ
Explanation of Solution
Reason for the portion of “OpenSSL” code containing the Heartbleed vulnerability:
- Based on the given it is said that the portion of open SSL (Secure sockets Layer) code contains errors because of the shortage in paid code checkers.
- Open SSL is an open source project involving the small team or community who releases code for free whenever it is required.
Heartbeat:
- Consider a client accessing a secure server.
- A client shares a particular amount of random number to its server.
- The server will in turn make copies of those random data and will send the data again to the client.
- This type of action is called as heartbeat which ensures both client and server are present in an active state.
- This action happens in the “TLS” (transport Layer Security) which ensures the protection of confidential data that being searched on the web.
- It will have its connection remained opened even if no data are being shared.
- This operation will have smooth process until an error or fault that it contains in the Open SSL.
Heartbleed:
- When an error occurs in the code of open source open SSL (Secure Socket Layer) cryptographic library “Heartbleed” vulnerability occurs.
- Error that could occur is, consider if the user or client intimates to send a particular amount of information but delivers only a few amount of information that it had intimated, the act of sending less amount of information than it committed to the server is the error, in this case the server in turn replies to the client by sending the information in the amount the client as intimated...

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
