SUSE security: Forgotten passwords, AppArmor

Filed under

Take advantage of the added protection that firewalls, anti-virus and anti-spyware programs offer, says James Turnbull. The author of Hardening Linux warns that, while the incidence of viruses and spyware on Linux are considerably smaller than on Windows-based platforms, they can still occur.

In this tip,'s security expert explains how you can run AppArmor on Red Hat Enterprise Linux 4 and explains why bugs in programs that cause vulnerabilities on one platform may not necessarily affect another platform.

Is it possible to use Novell's AppArmor on Red Hat Enterprise Linux (RHEL) 4?

James Turnbull: AppArmor was originally only available on SUSE, but at the start of 2006 Novell open sourced the application and made it available at Novell Forge. Since then, some community development has taken place and a port of AppArmor for, RHEL 5 specifically, (but also planned to be back-ported to other RHEL releases) is available. The port is currently still in development release and a production release is not yet available.

  • Why viral licensing is a ghost
    According to an historical and widely shared distinction, present on Wikipedia and generally supported by too many free software advocates including some lawyers, “Strong copyleft” (sometimes renamed “viral licensing”) refers to licences governing a copyrighted work to the extent that their copyleft provisions can be efficiently imposed on all kinds of derived works, including linked works: the same copyleft licence becomes applicable to the combination. At the contrary, "Weak copyleft" would refer to licenses (that are generally used for the creation of software libraries) where not all derived works inherit the copyleft license, depending on the manner in which it was derived: copies and changes to the covered software itself become subject to the copyleft provisions of such a license, but not the software that links to it. This allows programs covered by any license (even proprietary) to be compiled and linked against copylefted libraries such as glibc (the GNU project's implementation of the C standard library), and then redistributed without any re-licensing required.
