One of the big problems we face on our websites is the use of forms by “bots” in order to spread “spams” and that ends up causing a super use of our server resources, such as CPU and memory.
Basically, this procedure is the result of algorithms that identify the forms of our sites (contact for example) and start submitting information in them too much and automatically. With this, the production of “spam” ends up becoming a problem for our email services or even for our application’s database
A security feature in system authentication that has become quite popular recently is 2-step verification. The main banking and brokerage applications use their own apps to generate tokens that are dynamic (they are constantly updated in low cycles of time), and used as a 2nd factor for system access (the 1st factor is the traditional username/mail and password ).
However, if you do not want to implement your own token generator, you can use Google Authenticator, an application with the mentioned features (available for Android and IOS) and that can be easily integrated into your application or web system. In this post, I’m going to show you how to integrate your php application with Google Authenticator.
At a time when interoperability between systems has become increasingly important and the creation/use of APIs is increasingly ascending, it is always important to think about the consumption of third party services within our projects.
In php, although it is relatively simple to make requests “http” with the native resources of the language itself, it is recommended that a library be used for this purpose, since this way we have more security and resources that facilitate and make this process more agile procedure.
The git is great “face” in fashion now days when it comes to version control. This tool, created by Linus Torvalds (creator of Linux too), is based on the philosophy of distributed system, focused on speed. With this, each working directory of git , becomes a repository with complete history of the codes and their revisions (perhaps this is its great advantage over the decaying SVN).
To host git versioned projects , the most famous and used is GitHub ( www.github.com ). Several open source projects are available on GitHub and anyone can clone and use them. The registration on GitHub is free, but in the free account , your personal projects are public, that is, anyone can follow and use their codes. If you’re looking to create private repositories, you’ll have to shell out a few dollars a month.
