New research from the Pacific Northwest National Laboratory (PNNL) Data Sciences and Analytics Group shows that 25% of vulnerabilities appear on social media before the National Vulnerability Database (NVD). And it takes an average of nearly 90 days between a vulnerability being discussed on social media and the time it shows up in the NVD.
The reasons application vulnerabilities show up this often on social media before they get logged in the NVB are multiple. For developers just starting out in their career or those learning about a specific piece of software, they may not know that something is a vulnerability, that vulnerabilities need to be treated differently, and/or how to report vulnerabilities. In some cases, they may not know if the “issue” they found is a true vulnerability. Naturally, they look to the tools they regularly use when connecting with other developers—social media channels like GitHub, Twitter, and the various forums and discussions housed on Reddit.

On July 16, 2020, the European Court of Justice got rid of the four-year-old Privacy Shield agreement struck between the U.S. and the EU that had exposed Europeans to possible U.S. surveillance. The agreement had also allowed U.S. companies like Facebook and Google to store data about European residents outside of the region.
This move is yet another great example of the EU doing “right” by their constituents and holding tech companies responsible for their users’ data privacy. The news also builds on the EU’s General Data Protection Regulation (GDPR) leadership, extending its consumer protections and providing a model for the rest of the world to work from as global data privacy policies continue to evolve.

In this post, we continue discussing the functionality of the WHERE clause. We started with the basics of the logic using things like AND, OR, and LIKE or ‘=’. Now, we’ll expand into some other areas.
SQL Server provides you with all sorts of functions that can be used to manipulate strings, modify dates or times or perform arcane mathematical equations. The problem with these is that if you do them on columns in tables it can lead to performance issues. The trick then, is to not perform functions on the columns in the tables. We’ll cover this in more detail when we get to indexing, variables, and parameters. Just don’t get into the habit of putting functions on the columns in your tables in the WHERE clause.
