Warm‑up Story

Ada's First Threat Analysis

Ada was a new SOC analyst at a bank in Lagos. One morning, she received an alert about suspicious network activity. She had to quickly determine if it was a real threat or a false alarm.

She started by identifying the threat actor. Was it a hacktivist group, a cybercriminal, or a nation-state? She looked at the attack vector – how did they get in? Was it through a phishing email, a vulnerability in a web application, or a compromised password?

She assessed the vulnerability that was exploited and used the CVSS score to determine the severity. She then followed the organization's vulnerability management process to address the issue. Ada's quick thinking and knowledge of threats helped prevent a major breach.

Warm‑up Story

Chidi's Threat Hunting Discovery

Chidi was a senior SOC analyst at a bank in Lagos. He noticed that the organization was only responding to alerts, which meant they were always playing catch-up. He decided to implement a threat hunting program.

He used hypothesis-driven hunting to search for signs of compromise. He applied the MITRE ATT&CK framework to guide his hunts. He integrated threat intelligence to stay ahead of attackers.

During one hunt, he discovered evidence of a persistent threat that had been active for months. His proactive hunting prevented a major breach. Chidi learned that threat hunting is essential for staying ahead of attackers.
