This chapter covers
- General Stages of a cyber attack
- Types of threats
- Threat Identification
- Threat Prevention
As we have seen, due to their interconnected nature, networks are inherently susceptible to attacks. A single compromised device — whether due to a phishing email, a weak password, or unpatched software — can serve as a gateway for attackers to intercept or manipulate network traffic, move laterally across systems, and access sensitive data. These initial footholds often go undetected, enabling attackers to expand their reach undetected, which makes containment and remediation significantly challenging. This underscores the urgent need for robust, comprehensive security measures across all network components.
Attackers typically exploit the weakest link in a network’s defenses to bypass stronger protections. For instance, rather than targeting a well-protected server directly, they might compromise an employee’s device with a weak password and use it as a springboard to escalate privileges and infiltrate deeper into the network.
To effectively counter these threats, cybersecurity professionals must understand the mechanics of network systems and the tactics that attackers use to exploit them. This knowledge is critical for securing data in transit, protecting vital assets, and implementing proactive defense strategies.
