White paper on basic security and hardening procedures for AIX. Many of the features and functions shown throughout this guide are applicable to AIX 4.3 and above, but are more directed towards AIX 5.2. This guide attempts to cover a lot of ground and offers useful and necessary insight for anyone administering AIX machines.

This paper will discuss setting up encrypted communication for SNMP agents and trapd hosts through the use of Zebedee (Zee-bee-dee) UDP tunneling and encryption features. The goal is encrypted SNMP traps from the hosts to the management station and encrypted polling of the SNMP agent running on the host. All SNMP communication is handled by Zebedee with proper firewall filtering practices.

This document describes buffer overrun vulnerabilities on Sun Microsystems SPARC machines. We will begin by examining the SPARC architecture, looking at the registers and the stack. We will then go on to see exact how buffer overrun vulnerabilities occur and how control over the processes execution is gained under SPARC and then detail how, from here, the vulnerability can be exploited to gain control over the computer by looking at exploit code that spawns a shell under Solaris.

In the local network, the act of sniffing has become a serious threat. Malicious users can use sniffing techniques to steal confidential documents and anyone's privacy by sniffing the network. Sniffing causes privacy intrusion, and can be done simply by downloading free sniffer tools from the Internet and installing them into a personal computer that resides on the local network. The documentation below discusses the use of Address Resolution Protocol (ARP) packets to effectively detect malicious users when they are sniffing the network. The tool Promiscan implements the techniques discussed in this document.
