Our motivation for this study is to provide new information to a researcher based on our field of study: Networking Systems. This is because Cyber crime is becoming very widespread and it is imperative to improve measures used to counteract such threats. There are various research gaps based on awareness of cyber security, and different methods used in enhancing and troubleshooting network security. This research area can otter many opportunities in which justice can be served, creating awareness, making cyber space a more secure area and creating a new business niche based on security. Hence, for our study on Network Security, we read through 24 research papers published between 2008 to 2014. These documents were retrieved online from CAIDA and IEEE, along with other computer journals and articles. The 24 research papers were then summarized into 7 different research gaps to help enlighten a researcher in the topic of Network Security. Therefore, researchers can then take the initiatives to come up with solutions to the issues raised in this paper.
