Tricks to do client certificate authentications behind a reverse proxy
The problem we are tackling in this article is about X509 client certificate authentications. By definition and for security, a HTTPS request clear content cannot be spied. This is why when putting a reverse proxy behind the client and the internal web application, the HTTPS stream will be broken and we will loose all the client certificate data. -==- Here is some tips to forward without many efforts the client certificate data to the web application:

Log Files - Apache HTTP Server
Although we have just shown that conditional logging is very powerful and flexibly, it is not the only way to control the contents of the logs. Log files are more useful when they contain a complete record of server activity. It is often easier to simply post-process the log files to remove requests that you do not want to consider.

HowtoForge Linux Tutorials » Howto selbstsigniertes SSL Zertifikat erstellen
Wer kennt es nicht, man möchte gerne seinen Mailserver oder Webserver absichern mit SSL, weiss aber nicht wie er die SSL Zertifikate erstellen soll. Durch das benutzen von SSL wird die Kommunikation zwischen Client und Server verschlüsselt. Dadurch werden alle Daten, wie zum Beispiel Passwörter, Email Inhalte verschlüsselt übertragen. Der Vorteil von selbst signierten Zertifikaten gegenüber gekauften ist ganz einfach, sie kosten NICHTS! Um dies zu bewerkstelligen, benötigt man Openssl und in unserem Fall eine Linux Machine. In diesem Howto wird ein Debian Lenny 64Bit benutzt.

How to disable the support for SSLv2 LOW encryption ciphers? | Linux Windows System Administrator Help
There are known flaws in the SSLv2 protocol. A man-in-the-middle attacker can force the communication to a less secure level and then attempt to break the weak encryption. The attacker can also truncate encrypted messages.

I recently had a need to setup a private directory on my web server that could only be accessed by a handful of selected people. The content also needed to be encrypted in transit. This mini-HOWTO details how I did this on a Red Hat 8.0/Apache 2.0.40 server using mod_ssl and OpenSSL (0.9.6b and higher). Here are the goals of this small project:

Client Authentifizierung mit Apache
Apache ist der weltweit am häufigsten eingesetzte Web-Server, was Untersuchungen von Netcraft stets aufs neuste belegen. Ein Apache-Server stellt anfragenden Clients verschiedene Daten zur Verfügung, auf die auf unterschiedliche Art zugegriffen werden kann. Teilweise ist es wünschenswert, dass die Daten nur von dazu autorisierten Clients abgerufen werden können. Apache bietet hierzu zwei verschiedene Lösungsansätze, auf die im weiteren Verlauf näher eingegangen wird.

Sicherer Apache mit ModSecurity
Ende 2003 verglich Ivan Ristic das Betreiben eines Webservers mit »Russisch Roulette« (vgl. Introducing mod_security). Gleichzeitig machte er auch auf eine - von ihm - entwickelte Lösung zur Schadensbegrenzung aufmerksam. Das Programm mod_security bietet verschiedene Mechanismen zur Erkennung, Abwehr und Protokollierung von Angriffen auf Webserver. -=- Genau genommen handelt es sich bei mod_security um ein Modul zur »Feststellung und Verhinderung von Einbrüchen in Webserver« (Web Intrusion Detection and Prevention). Die Funktionsweise orientiert sich im wesentlichen an seinem »großen Bruder«, snort. Analog zu diesem IDS (Intrusion Detection System) wird der ein- und ausgehende Datenverkehr auf bestimmte Merkmale (»Signaturen«) untersucht, die für einen »Angriff typisch sind«. Wird eines dieser festgelegten Angriffs-Muster erkannt, wird eine vorherher definierte Aktion ausgeführt.

Content Types - Web Developer Boot Camp
Content Types are a generalization of the concept of file types for use over the internet in email and on the web where file extensions and operating system based metadata are not always available. Content Types are the means by which the appropriate programs are used to view various media types such as web pages, images, and multimedia. -=- The history of Content Types can be traced back to the beginning of email. Although RFC 822 defined the standard for text email messages, the need quickly arose to be able to send messages containing more than just plain text. In order to allow the receiver of a message to determine how to process the non-text portions of a message, the concept of Content Type was introduced in RFC 1049 and [...]
