Study Notes

Inventory and Control of Enterprise Assets

Goal: Actively manage all hardware devices on the network to ensure only authorized devices have access, and unauthorized devices are found and prevented from accessing the network.
Rationale: Attackers continuously scan address spaces for new systems that might be unprotected.
Components involved:
- Asset Inventory Database
- Network Level Authentication (NLA)
- Public Key Infrastructure (PKI)
- 802.1x
- Passive Device Discovery
- Active Device Discovery
- Analytics System (Alerting/Reporting)

Information System

Definition: A set of applications, services, information technology assets, or other information-handling components.
Includes:
- Methods and procedures
- Data
- Technology (software/hardware)
- People

Fundamental Questions

How do we manage information security to ensure an information system (or an entire organization) is secure and stays secure?
How do we know that we are secure?

Software Whitelisting

Goal: Actively manage all software on the network to ensure only authorized software is installed and can execute, and unauthorized software is found and prevented from installation/execution.
Rationale: Attackers continuously try to find vulnerable software versions, and employees install/run software from third parties that might cause problems.
Implementation:
- Devise a white-list of authorized software and versions required in the enterprise.
- Deploy a software inventory tool to track the operating system and applications installed on each asset.
