#RSAC


Quick Win 1 - Control 1 – HW Inventory Implement an automated discovery engine (active/passive)

Quick Win 3 – Control 2 – SW Inventory Scan for Deviations from Approved List

Quick Win 3 – Control 3 – Secure Configurations Limit Admin privileges

Quick Win 10 – Control 4 – Vulnerability Scanning Risk rate by groups

22

#RSAC


Measure Success Control 1: Detect new machines in 24 hours

Control 1: How many unauthorized machines on network?

Control 2: How many unauthorized software packages installed?

Control 3: Percentage of machines that do not run an approved image ?

Control 4: Percentage of machines not scanned recently (3d)?

Logins - user, date, type

Scans - user, date, type, target, duration

Reports - user, date, type, duration, size

Hosts – machine, date, active, fixed, severity counts, scores

Vulnerabilities – id, severity, cvss, age

Software – name, publisher

Certificates – subject, validdate, signer, self-signed

Ports – date, ports
