Improved Network Security and Performance with a Reverse Proxy

Welt-Laptop-Sicherheit
Providing services on the Internet is part and parcel of day-to-day work in a company nowadays, but you don’t always want the server to be directly accessible from the Internet when doing so. A reverse proxy can control access in such cases using ACLs (access control lists). The reverse proxy can also reduce the number of IP addresses required, as it can provide access to multiple systems behind one IP.

How-To: Administration of Groups in UCS

Whether it’s for access to the UCS portal, printers, or files, users’ authorizations in UCS are defined by their group memberships. This process facilitates the administration of authorizations in large environments in particular as there is no need to assign individual authorizations to each user separately. The group administration reduces the administrative efforts required when mounting new services to the central IDM especially if these services can be made available to defined groups in one go.

Only a short percentage of users is changing their passwords on a regular basis. And when choosing a password, „easy to remember“ usually beats „secure, unique and complex“. Of course, you want to make sure your users choose a username and password combination that is secure. Forcing users to do so often results in storing the login credentials in the browser. Some systems force their users to change the password on a regular base, resulting in frustrated users or employees.

Chrome Warns Users against HTTP – Configure with Let’s Encrypt free SSL Certificates for UCS

With the announcement of July 23, 2018 at the beginning of February this year, Google created a new milestone on the path to a fully encrypted web.
