Cybersecurity and Confidential Computing Architectures

This chapter introduces computing architectures suitable for applications that require an exceptional assurance of security. Critical application areas like national security systems and financial transaction processing demand this high level of protection. These systems must be resilient against a broad range of cybersecurity threats, including malicious code, covert channel attacks, and attacks enabled by physical access to the computing hardware. Topics addressed in this chapter include cybersecurity threats, encryption, digital signatures, and secure hardware and software design.

After completing this chapter, you will be able to identify the categories of cybersecurity threats a system will face and understand the security features of modern computer hardware. You will understand how to avoid security gaps in system architectures and how a secure computer architecture can help enforce security in software applications...
