Abstract

There exist many documents, guidelines and application-level programs attempting to secure various operating systems (OS), but there is much less documentation and software for protecting lower levels subsystems such as the Basic Input Output System (BIOS). Security professionals are well aware that the security on any system is as strong as its weakest link as an attacker will seek to break into a system with the least amount of effort. In this chapter we will focus on the BIOS, and describe its main functions as well as the potential for attacks and countermeasures. After discussing the BIOS and analysing how it might be compromised, we will go on to consider rootkits. Installing a rootkit is often the next stage of an attack once the BIOS has been compromised, allowing the attack to take full control of the target system. We will discuss what rootkits actually are, how to identify that a system has been infected with a rootkit, and how to try and prevent such attacks in the first place. It should be note that the issues raised in this chapter have also provided justification for specialist hardware security measures such as the Trusted Platform Module (TPM) [1, 2, 3] described in Chap.  4.
