Server-side includes do not solve all problems—but what software does? Rather, SSIs were created so that non-programmers could create dynamic output. Over time, they have expanded to the point where they can now include conditional statements, which are a first step toward actual programming. As we have seen, though, programmers can benefit from many of SSI's features, especially when it comes to including simple information inside of pages of HTML, such as standard headers or a file's last modification date.
There are a number of other commands available from within SSIs, including #exec, which allows you to run a program and incorporate its output into a page of HTML. (You can also use #include to bring in the output from a CGI program, even if you use IncludesNOEXEC rather than Includes in the Apache configuration.)
In some cases, though, such simple server-side includes might not be enough. Over the next few months, we will look at several software packages that take the idea of server-side includes one step further, making a complete programming language available inside of HTML files without the need for CGI programs.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
