Network Security Monitoring: Course Overview and Reflections

The term "network security monitoring" can sound daunting and dry even to someone that is already somewhat aware of the technical aspects of the field and its importance. While network security is of vital importance to many organizations and entities involved in all manner of activities around the world, monitoring the traffic over these networks for the potentiality of security risks can, to those uninitiated in the intricacies and uncertainties of the practice, seem like a boring crossover between data processing and air traffic control. This course and the readings and exercises of which it is partially comprised made it very clear that network security monitoring is almost as much an art form as it is a science, with constantly evolving needs and mechanisms that make the task and profession not simply more interesting than the title seems to initially imply, but a truly exciting and cutting-edge occupation with growing potentials and ever-increasing future demands.

Summary of Experience

My experience throughout this course has been both edifying and exhilarating, as I have not only gained a great deal of knowledge about many of the generalities and the specifics of network security monitoring but have also come to better appreciate the context (and contexts) in which network security monitoring takes place and the manner in which all of the mechanisms and impacts of this monitoring come together. While many of the basic underpinnings of network technology and security were already familiar to me, I quickly learned how much I had yet to become acquainted with, and this course was excellent in delivering the depth and the breadth of information necessary to provide a truly adequate foundation for building knowledge in the network security field. The information was also delivered at an effective pace, and while I did not ever feel overwhelmed or in over my head, I also did not feel bored or that the material was overly repetitive, and this made it much easier to absorb the information presented and to appreciate for what it was worth and how it all fit together. Overall, I feel that I not only gained the necessary foundational knowledge in this area, but that I also became equipped to ask better questions and seek out better avenues of information and learning in the further pursuit of my education and my eventual career.

As far as the specifics of the information that I obtained from the course, the number of different issues and perspectives that exist in the broader arena of network security monitoring was surprising and revealing. The discipline is far more complex and involved than an initial glance might suggest, and the course covered many areas of the filed that I would never have imagined might exist, and thus could never have effectively sought information about on my own. One of the most significant issues I (and I think anyone) have faced in expanding my technical and area-specific knowledge is in ascertaining enough of the functional basics to be able to ask meaningful questions and knowingly pursue further information, and again this course has been excellent in bringing this about. From user issues to different types of attacks and threats to the many different means of responding to observed issues, this course has touched on a large number of the many facets in network security monitoring and thus has empowered me in being able to seek my own answers, as well.

Potential Future Directions

One of the reasons this course was so attractive to me in the first place was the degree to which I expected the knowledge I would gain to be directly transferable to the workplace, and I was certainly not disappointed in this regard. It was easy to see -- impossible to miss, in fact -- how each of the mechanisms, relationships, and individual pieces of information acquired throughout the course would be directly applicable to the real-world practice of network security monitoring and the needs of network-dependent organizations. While taking the course did not directly change my plans to pursue a career in a field that requires or is at least related to network security knowledge, it did lead me to consider the singular role of a network security monitor as a viable career in and of itself, at least for a certain period. Ultimately, I think I would like something more varied as a life-long occupation, but including network security knowledge and network monitoring skills in my professional repertoire and experience is definitely something I would like to actively pursue. The substantial amount of information I gathered on network security monitoring through this course has definitely had an impact on my practical appraisal of this area.
