Grsecurity
Grsecurity is a suite of patches (distributed as a single patch file) for the Linux kernel that are an attempt to improve the security of a Linux system. Grsecurity is based on a port of some previous patches for the Linux 2.2 kernel, including Openwall and PaX, which have never been ported to the 2.4 kernel. Grsecurity provides some updates to these patches and has been ported to the Linux 2.4 kernel. This article will offer a brief overview of grsecurity.

IPTables Linux firewall with packet string-matching support
Linux firewalling code has come a long way since the time ipfwadm was introduced in kernel version 1.2.1 in 1995. Ipfwadm enabled standard TCP/IP packet filtering features such as filtering by source/target addresses and port numbers. Then, in early 1999, when the first stable 2.2.0 kernel was released, firewalling code was replaced with new ipchains-controlled code. New features included support for chains of rules, fragmentation handling, better network address translation (NAT) supp...

A Simple Oracle Host-Based Scanner
As with any large software package, the default installation of Oracle does not provide for the most secure system out of the box. Indeed, some aspects of the default installation are remarkably insecure. This paper will explore the scanning of an installation of Oracle's RDBMS and, in doing so, will investigate some common security deficiencies.
