Python for active defense: Network

Infosec Institute - 

ATT&CK is a well-known cybersecurity tool that breaks the lifecycle of a cyberattack into discrete goals that the attacker may pursue (called “tactics”). For each tactic, ATT&CK defines several techniques for accomplishing these goals.

MITRE Shield is a newer tool in the same vein as MITRE ATT&CK. Instead of focusing on offensive cybersecurity, it describes tactics and techniques that defenders can employ to proactively defend against an attacker via active .

When implementing active defense, network-level data collection and deception is a critical part of this strategy. -level techniques are represented across many tactics of the MITRE Shield framework.

PCAP collection for active defense

Many of an attacker’s activities during a campaign are performed over the network. Initial access is often gained over the network, and network traffic is created when an attacker is exploring and expanding their foothold within an organization’s environment.

This makes visibility into the network level essential for active defense.

PCAP collection

An organization might want to collect network traffic data for a variety of different purposes. Analyzing network traffic at an enterprise scale can enable a company to detect known or identify anomalies within an organization’s network.

Alternatively, network traffic collection can
