RESPOND TO THE TWO PEER POSTS BELOW BY ANSWERING THE FOLLOWING QUESTIONS:

QUESTION(S): In your responses to your peers, address the following:

• If you were charged with designing a new network and introducing Open Shortest Path First (OSPF) instead of RIP, how would adopting OSPF affect the fundamental design principle your peer identified in their initial post? Consider addressing the effects on both security and network traffic in your reply.

PEER POST # 1

I think principle of least privilege can be utilized when RIP is chosen as a routing protocol. Adversarial mindset in this scenario must take into consideration the vulnerabilities and the ways in which RIP can be exploited.

Using the principle of least privilege, network entities will have the minimum level of routing information required for proper functionality. RIP doesn’t have understanding of network topology, it only counts the number of hops. This can entice a potential attackers to use route poisoning or route injection. Attackers could inject false routing information, giving them access to the network. If the RIP has limited access to only the necessary routing information, it would keep the network much more secure. The attacker would only have access to minimal data. Therefore, this could minimize the breach.

PEER POST # 2

Employing an adversarial mindset affects decisions to implement RIP in the network by utilizing the minimization of implementation fundamental design principle, in which all routing is done automatically. Adversarial mindsets allow people to think like the person or people who are opposing them in each circumstance. Having this type of mindset will make securing a network much simpler and easier to construct. Although RIP works on many design principles, minimization of implementation concerns limiting chances of data breach by removing components to make a program more secure. In other words, resources should not be shared using common mechanisms. Limiting current size and complexity while simultaneously opposing the growth of new ones is necessary for minimization.

Reducing the number implementations means this design principle generally applies to small networks where RIP can flourish. The routers can be configured to update regularly or less frequently by forcing update intervals. Because every router taking part in RIP routing is identified with an identical update interval, the implementation time is kept to a minimum. One vulnerability of this is with less implementations it is not as suitable for larger networks that have different paths. Another concerning vulnerability is by promoting a new route that has a superior metric than the current route, existing routes can be removed. When implementation is minimized, child routes are missed, which poses a risk to data packets sent via the route that contains child routes. This essentially exposes your network to the risk of multiple types of attacks being made by the child routes. Having an adversarial mindset can help you create a more secure network while being aware of the possible vulnerabilities.
