Data is exploding, with a staggering amount of information being created every single day. This data has become a goldmine for businesses. By analyzing this data mountain, organizations can guess what customers will do next. This helps them stay ahead of the competition.
However, the sheer volume, speed of arrival, and inherent variability of big data demand a fresh perspective on data analysis. In this guide, I’ll share some of the best practices for big data governance and security that can help data scientists tame this monster of information.
Best Practices for Big Data Governance and Security
Data governance is a game plan for handling all your company’s information. It can be flexible with suggestions or stricter with rules, depending on what works best for your company. Remember, big data constantly changes and grows with new sources and analysis tools.
This means data governance can’t be a one-time thing anymore. It’s about tracking who’s accessing it and how it’s being used. You need to establish a data governance team to ensure everything runs smoothly. This team is the data watchdog. It champions data quality, proper use, and compliance with regulations. Even though companies differ, there are security and governance practices that apply universally. Let’s look at the role of this big data governance team and the best data governance and security practices.
Implement Quality Control Measures
Big data presents massive amounts of information in various formats and arrives faster than ever. The problem is that as this data gets splashed around to different systems and used in new ways, its quality can suffer.
Data governance comes with a set of rules and tools to keep everything organized. That’s where software quality control and testing come in. Implement quality control measures by regularly checking your data to find and fix any problems fast.
Make Everything Simple and Clear
Big data throws massive amounts of information in various formats and comes in faster than ever. The speed makes figuring things out with analytics a real brain twister. That’s why it’s essential to keep things simple.
By focusing on clear, understandable solutions, big data scientists tackle big data’s complexity and build things that won’t become a maintenance nightmare. Remember, more data doesn’t always mean a better analysis.
The key is to be strategic about where you get your information. Sometimes, a smaller, well-chosen set can actually be easier to work with and give you just as good, if not better, results. It’s all about the volume and speed of that data, no matter how many places it comes from.
Establish Data Source Protocols
Imagine trying to do amazing data analysis, but you’re unsure if the information you’re using is reliable. That’s the struggle data scientists face without clear rules and well-defined steps to check their data. To build trust, we need SLAs on how data flows inside and outside the company.
A scoring algorithm is a great way to do this. Scoring systems are like little trust meters for data sources. The higher the score, the more confident data scientists can be that the information is accurate. This helps them pick the best sources to answer new questions that pop up.
The scores are not fixed; they are updated as new information about the reliability of a source becomes available, ensuring accuracy.
Enforce Data Security and Privacy
Big data is like a treasure. You need to keep it safe and ensure you’re not peeking into things you shouldn’t. That’s why data governance is about following privacy rules and strong security measures. Think of it as a two-part shield: privacy laws prevent unauthorized access to sensitive information, while security measures protect against malicious actors.
A good data governance policy makes sure both of these things are covered. Don’t wait to patch holes in your privacy policy every time a new regulation pops up. Bake data privacy right in from the start. When it comes to security, understand what kind of security you actually need to avoid a tangled mess of programs and wasted effort.
The aim is to keep your data safe without slowing everyone down or locking out your team. With good privacy and security, your data will stay secure, and you’ll stay on the right side of the law.
Keep Check of Data Combinations
Mashing up data for analysis is excellent, but you need to be careful not to step on any privacy toes. Just because you anonymize customer info doesn’t mean you’re in the clear. Combining other bits of data can sometimes lead to a surprising mess.
Big data is like a puzzle. The wrong pieces put together can paint a whole new picture you might not want. That’s why GDPR and other privacy rules are there: to make sure we’re smart about how we combine data and keep everyone’s information safe. For instance, you have a dataset with birthdays, zip codes, and genders.
With just this information, you can identify 87% of people in the US. That’s why things can still get tricky, even when you take names out. So, dive into your big data and see what kind of information can snitch on someone’s identity. You can remove specific details or make things more anonymous, so no one’s privacy gets exposed.
Communicate Clearly and Punctually
Data governance is a journey, not a destination. No matter where you are on that road, communication is key. Keep everyone in the loop, from the big bosses to the data whizzes. This way, there are no nasty surprises, and everyone celebrates the wins together and learns from the setbacks.
Create a list of the stakeholders and make sure the information you share is readily available and digestible. Keep your communication clear and simple without drowning people in jargon.
Final Thoughts
The best big data governance and security revolve around technology, processes, and people. People should know where data comes from and who’s responsible for keeping it accurate. There should be clear steps to follow whenever your data needs an update. Finally, technology should be able to keep everything organized and secure.
