Journal Entry #2
A framework, in general terms is a supporting structure. You could say that the skeleton is a framework of the human body, or rebar is a framework for a building. In programming terms, a framework is a general abstraction that provides a standard program that lets the user insert their own code for project specific functionality, similar to a default template. Frameworks are useful because they create a broad template usable by a wide range of users who can tailor the specific details to their own individual needs. The framework created by NIST provides “…a common language for understanding, managing, and expressing cybersecurity risk, and is a tool for aligning policy, business, and technological approaches to managing that risk” (“Framework for improving critical infrastructure cybersecurity”, 2018, p. 6). It has five specific functions for people using the framework to step through simultaneously. The first step is Identify, things like risk assessment and asset management fall under this. Identify risks to the entity’s assets. Next is to protect, fairly self explanatory; come up with safeguards to make sure your services can be delivered. Detect is a third function, and this entails creating ways to let you know when a cybersecurity breach occurs; monitor your network continuously. Next is Respond which is, again, self explanatory. How do you respond to a cybersecurity event? Do you hold an internal meeting to discuss the incident, who analyzes the breach and the ramifications of it? How do you improve on your current monitoring and/or security practices in place to prevent this kind of breach in the future? The last function listed in the Framework is Recover: get your services back up and running to pre-breach functionality. Again, these five functions are meant to be done at the same time, they’ve just been listed in this order for simplicity’s sake. These functions are meant to create a path for assessing your risks, putting security in place, and then responding and recovering to any form of cybersecurity event.
