Using Dynamic Blockist to counter 0-day attacks - R&D project from ISAP interns.
THE PROBLEM of "Zero-Day" Threat:
A zero-day attack uses a previously unidentified vulnerability or malware artifact that has no known signature
The Danger: Traditional security relies on "signatures" (like a digital fingerprint) to recognize threats. Because zero-day attacks are brand new, signature-based defenses are often too slow, leading to a successful infection rate of over 50%.
The Speed Gap: It can take days, weeks, or months to develop a manual patch for a new exploit—way too slow for the internet’s fluid environment.
The Solution is to track the "Where" instead of the "What"
IP-Based Reputations: Instead of trying to identify every new piece of malware (the "what"), dynamic blocklists track hostile servers (the "where")
IP Reputation Services (TRS): These automated systems assign scores to IP addresses based on their behavior. If a server is known to be hostile, it gets a bad reputation score
Force Multiplier: This automated approach acts as a "force multiplier" for security teams, protecting the network at the speed of detection rather than manual investigation!
