Stack Smashing Protection for Debian

Post date: June 23, 2006, 22:06 Category: Security Views: 3679 Comments
Tutorial quote: Since we last covered the use of Stack Smashing Protection (SSP) the default compiler for Debian Sid has been upgraded to include it, with no need for custom patching. Read on for a brief demonstration of how it can be used to prevent attacks.

The default C compiler for Sid, which will be used in Etch too, is GCC v4.1. This releasecontains the SSP patch which previously needed to be applied manually (we demonstrated applying this patch for GCC v3.4 a long time ago).

Since the SSP patch is included in the compiler by default it is suddenly a lot easier to start working with it.

Preventing Brute Force Attacks With BlockHosts On Debian Etch

Post date: September 30, 2007, 09:09 Category: Security Views: 4873 Comments
Tutorial quote: In this article I will show how to install and configure BlockHosts on a Debian Etch system. BlockHosts is a Python tool that observes login attempts to various services, e.g. SSH, FTP, etc., and if it finds failed login attempts again and again from the same IP address or host, it stops further login attempts from that IP address/host. By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.

Restricting Users To SFTP Plus Setting Up Chrooted SSH/SFTP (Debian Squeeze)

Post date: September 6, 2011, 07:09 Category: Miscellaneous Views: 6714 Comments
Tutorial quote: This tutorial describes how to give users chrooted SSH and/or chrooted SFTP access on Debian Squeeze. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of. I will also show how to restrict users to SFTP so that they cannot use SSH (this part is independent from the chroot part of this tutorial).

Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch

Post date: December 18, 2007, 12:12 Category: Miscellaneous Views: 4133 Comments
Tutorial quote: When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

Make Browsers Cache Static Files With mod_expires On Apache2 (Debian Squeeze)

Post date: March 10, 2011, 11:03 Category: Installing Views: 3567 Comments
Tutorial quote: This tutorial explains how you can configure Apache2 to set the Expires HTTP header and the max-age directive of the Cache-Control HTTP header of static files (such as images, CSS and Javascript files) to a date in the future so that these files will be cached by your visitors' browsers. This saves bandwidth and makes your web site appear faster (if a user visits your site for a second time, static files will be fetched from the browser cache). This tutorial was written for Debian Squeeze.
