Just as she leaned back, her SIEM dashboard lit up. An alert. 2:17 AM. A rogue access point had just appeared in the CFO’s wing. But unlike last time, the network didn't panic.

Elena Vasquez hated the quiet hum of the server room at 2 AM. It sounded too much like a heartbeat slowing down. For the past six months, she had been living inside a single book: CCNP Security SISAS 300-208 Official Cert Guide . Its spine was cracked, its pages coffee-stained, and its margins filled with her panicked, tiny handwriting.

Three months ago, a shadow had slipped through the perimeter of Apex Financial. Not a virus. Not a worm. A ghost. Someone had used a legitimate credential—a janitor’s badge, long since deactivated—to walk right through their Cisco Identity Services Engine (ISE) like it was a turnstile.

Click. The sound of the server rack made her jump. Ccnp Security Sisas 300 208 Official Cert Guide
