When IT visionaries give presentations about the Digital Transformation, they usually talk about large enterprises with teams of experts working on exciting stuff like heterogeneous multi-cloud application architectures with blockchain-based identity assurance and real-time behavior analytics powered by deep learning (and many other marketing buzzwords). Of course, these companies can also afford investing substantial money into building in-depth security infrastructures to protect their sensitive data.
Unfortunately, for every such company there are probably thousands of smaller ones, which have neither budgets nor expertise of their larger counterparts. This means that these companies not only cannot afford “enterprise-grade” security products, they are often not even aware that such products exist or, for that matter, what problems they are facing without them. And yet, from the compliance perspective, these companies are just as responsible for protecting their customer’s personal information (or other kinds of regulated digital data) as the big ones and they are facing the same harsh punishments for GDPR violations.
One area where this is especially evident is database security. Databases are still the most widespread technology for storing business information across companies of all sizes. Modern enterprise relational databases are extremely sophisticated and complex products, requiring trained specialists for their setup and daily maintenance. The number of security risks a business-critical database is open to is surprisingly large, ranging from the sensitivity of the data stored in it all the way down to the application stack, storage, network and hardware. This is especially true for popular database vendors like Oracle, whose products can be found in every market vertical.
Of course, Oracle itself can readily provide a full range of database security solutions for their databases, but needless to say, not every customer can afford spending that much, not to mention having the necessary expertise to deploy and operate these tools. The recently announced Autonomous Database can solve many of those problems by completely taking management tasks away from DBAs, but it should be obvious that at least in the short term, this service isn’t a solution for every possible use case, so on-premises Oracle databases are not going anywhere anytime soon.
And exactly for these, the company has recently (and without much publicity) released their Database Security Assessment Tool (DBSAT) – a freeware tool for assessing the security configuration of Oracle databases and for identifying sensitive data in them. The tool is a completely standalone command-line program that does not have any external dependencies and can be installed and run on any DB server in minutes to generate two types of reports.
Database Security Assessment report provides a comprehensive overview of configuration parameters, identifying weaknesses, missing updates, improperly configured security technologies, excessive privileges and so on. For each discovered problem, the tool provides a short summary and risk score, as well as remediation suggestions and links to appropriate documentation. I had a chance to see a sample report and even with my quite limited DBA skills I was able to quickly identify the biggest risks and understand which concrete actions I’d need to perform to mitigate them.
The Sensitive Data Assessment report provides a different view on the database instance, showing the schemas, tables and columns that contain various types of sensitive information. The tool supports over 50 types of such data out of the box (including PII, financial and healthcare for several languages), but users can define their own search patterns using regular expressions. Personally, I find this report somewhat less informative, although it does its job as expected. If only for executive reporting, it would be useful not just to show how many occurrences of sensitive data were found, but to provide an overview of the overall company posture to give the CEO a few meaningful numbers as KPIs.
Of course, being a standalone tool, DBSAT does not support any integrations with other security assessment tools from Oracle, nor it provides any means for mass deployment across hundreds of databases. What it does provide is the option to export the reports into formats like CSV or JSON, which can be then exported into third party tools for further processing. Still, even in this rather simple form, the program helps a DBA to quickly identify and mitigate the biggest security risks in their databases, potentially saving the company from a breach or a major compliance violation. And as we all know, these are going to become very expensive soon.
Perhaps my biggest disappointment with the tools, however, has nothing to do with its functionality. Just like other companies before, Oracle seems to be not very keen on letting the world know about tools like this. And what use is even the best security tool or feature if people do not know of its existence? Have a look at AWS, for example, where misconfigured permissions for S3 buckets have been the reason behind a large number of embarrassing data leaks. And even though AWS now offers a number of measures to prevent them, we still keep reading about new personal data leaks every week.
Spreading the word and raising awareness about the security risks and free tools to mitigate them is, in my opinion, just as important as releasing those tools. So, I’m doing my part!
