Security is becoming an increasingly important topic as business applications become more frequently accessible through the web and are, as a result, more vulnerable to threats. As 4D is closely paying attention to security matters, in 4D v16 R5 we are providing you with a couple of security improvements, and one of them relates to the web users’ password protection through password hashing.
By the way, if you want to know more about how 4D is helping you to protect your data and with the security in general, I recommend you to take a look at this blog post.
Over the years, security has become a core topic for business applications. Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as “SSL”, are cryptographic protocols that provide communications security over a computer network. The TLS version that your application is using for web or client/server connections, for instance, contributes to its security level.
4D supports all TLS versions: 1.0, 1.1 and 1.2. The protocol version used is negotiated between the server and the client when establishing the connection. To increase the security level, beginning with 4D v16 R5, the default minimum supported version is TLS 1.2, older versions are rejected, as they could be unsecure.
According to neuroscientists, we respond better and faster to a visual form than any other type of representation. That’s why graphs and charts are clearly a key to a better understanding of data.
So if you’re looking to display bar charts, histograms, or pie charts which are modern and fully compatible with the leading browsers, but also more suitable for the way the human brain processes information, Google Charts is one possible answer. The available chart types in Google Charts is varied: from the classical bar/column/pie charts, Google Charts also offers elaborated graphs such as Treemap, Candlestick and Gauge charts.
We are moving forward with 4D v16 on preemptive multi-threading as the 4D Web Server is also becoming preemptive. Just click one checkbox and your application will support more simultaneously connected users, and process more requests in parallel. For requests using a lot of CPU time, execution can be up to 2 times faster!
The WEB Session commands have been adapted to 4D Mobile session. Now, you can save the results of a query or an inter-process variable related to a given 4D Mobile session. For example, with new handling of 4D Mobile sessions, you can manage the cart of your users.
