How To Block Spam Before It Enters The Server (Postfix)

Post date: June 4, 2007, 23:06 Category: Security Views: 5204 Comments
Tutorial quote: The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT (vmx) or AMD-V (svm). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Taking advantage of SELinux in Red Hat Enterprise Linux

Post date: April 15, 2005, 21:04 Category: Security Views: 4739 Comments
Tutorial quote: The release of Red Hat Enterprise Linux 4 debuts the first commercially supported inclusion of Security-Enhanced Linux (SELinux). An installation of Red Hat's latest enterprise operating system has SELinux installed and enabled by default. In the past SELinux has been criticized for a lack of commercial support, many big sites were unable to use it due to the lack of support (Fedora Core 3 doesn't have the support that they require). Now in Red Hat Enterprise Linux 4, SELinux is a supported part of the OS, and such objections to the use of SELinux have gone away. SELinux is now widely regarded as being suitable for the largest sites.

Giving users a home directory automatically

Post date: June 16, 2006, 21:06 Category: System Views: 3717 Comments
Tutorial quote: If you are using LDAP or NIS to manage users you might discover users having problems because they don't have a home directory on each machine they can connect to. Thankfully there is a simple solution for creating home directories upon demand for users.

The Pluggable Authentication Modules library, or PAM, is a collection of shared libraries which control how users login to systems. There are a number of modules installed which can be used to restrict user access to systems in different ways. There are also several utility modules which can be used to customise login behaviour.
