Principals of Information Security 4th Edition Questions Chapter 6 Questions 1. What is the typical relationship among the untrusted network‚ the firewall‚ and the trusted network? The relationship is that data is only limited to what firewalls allow via specific places called “ports”. There is the untrusted network on the outside‚ then the firewall which prevents unwanted or suspicious connections‚ and the trusted network is what lies within the bounds of the firewall. 2. What is the relationship

Summary All tasks are completed. In this assignment‚ the main task is to implement the Sliding Window Protocol (SWP) in java. However‚ the sample code provided in the lecture notes is in C. Therefore‚ this main task is divided into the following sub-tasks: Port the SWP code to Java Implement missing timer related classes and functions The following sections will cover these three sub-tasks. Porting the code Minor changes were made in order to change the syntax of the code to

network to automatically switch the path in case of a network failure. There is various kind of spanning tree‚ including STP‚ RSTP‚ PVST‚ and MSTP. In this section‚ we will take a look at an implementation of the most basic of STP. Spanning Tree Protocol (STP: IEEE 802.1D) handles a network as a logical tree and by setting all ports for each switch (sometimes called a bridge in this section) to transfer frame or not it suppresses occurrence of broadcast streams packets in a network having a loop
