In the days of mainframe computers and the first smaller networks, terminals were a crucial building block for sharing hardware and software resources. It is no coincidence that terminal servers – the central administrative entity of such networks – are in demand decades later, now that applications are to be made available to multiple users.
With Linux, access rights for directories and files are often set through the terminal where file owners can be defined and groups can be assigned. With the ‘chmod’ command, user classes can be assigned certain file rights. Access rights in the Unix file system can be changed in two different ways: symbolic or numeric. Find out more about both notation types here.

Before a homepage goes live, website operators should have a legal notice in place, also called an “Impressum.” Most internet pages also require a provider identification. Depending on the industry and the contents of the website, special information must be provided. Otherwise, warnings and fines may be issued.

This notifies site visitors of the information they are disclosing about themselves and what their data will be used for. But what kind of information should this declaration contain, what has changed since the new EU General Data Protection Regulation law, and how does this affect companies in the US?
The EU plans to significantly tighten data security online: With the ePrivacy Regulation, the collection of personal data will only be allowed following explicit allowance. At this point, it’s not certain what exactly will be included in the ePrivacy Regulation: Here, we’ve consolidated what we already know. As a website operator, it makes sense to inform yourself on the changes the regulation...
Since May 25, 2018 a new European law on data protection has been in place. However, despite it being relevant to day-to-day business, many companies and website operators are still unattuned to the General Data Protection Regulation (GDPR).
