Gaining Access: Attack and Defense Methods and Legacy Systems

Abstract

This chapter is a more technical chapter. It outlines and analyzes a series of cyberattack measures and then discusses counters and defenses. The attacks include the use of zero-days, rootkits, and Remote Access Trojans and remote access more widely and common tactics, techniques, and procedures. The counters and defenses include Firewalls, Demilitarized Zones, Intrusion Detection Systems, and zero trust security models. It then moves onto an examination of legacy systems and patching before looking at the targeting of companies in the supply chains that make up critical infrastructure.
