Where influences how.

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Overall IT, InfoSec and Compliance Structure

“Normal” IT Stuff

Infrastructure

Telecommunications

IT Services

Operations

User Services

Media Technology

Enterprise Computing

Also

IT Project Management

IT Budget Management

CISO – “Technical” Security

CICO – “Information” Security

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Constant InfoSec Context • Compliance needs (FERPA, GLBA, HIPAA, PCI…)

• Risk assessments

• News (especially of peers)

• Case studies

Remember: Don’t bring problems, bring solutions

Easy on the FUD!

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

True Story.

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

The Challenge

Technical security (firewalls, VPNs, AV, etc.) is justified, specified and PURCHASED.

Operational security (patching, CM, coding) is proceduralized, centralized and MANDATED.

User security (behavior) is encouraged , coaxed, and “hoped for”.

Security

Tech Ops Training

Behavior

Awareness

…hmmmm security…

Training vs. Behavior?

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

The BIG Deal…

User security depends on user behavior; not on compliance, or training, or awareness.

If behavior does not change the awareness has no real value.

If this change is real it must be measured.

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

The Plan

Develop comprehensive training and assessment system which will:

#1 - Improve Behavior

#2 - Apply training appropriately

#3 - Develop metrics and analytics

#4 - Find and fill gaps (process, not event)

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

TARR System (Train, Audit, Review, Remediate)

Combine HR, people, and security survey data

Score risk: per person, department, division

Target training where appropriate

Rinse / repeat (2010, 2012, 2014,…)

• What do you handle?

• Where do you get it?

• Where do you keep it?

• What do you do with it?

Survey Construction

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Security Score

Each “usage” type has a score and a risk value

Scoring:

add 1 for low-risk answer

add 100 for medium-risk answer

add 10000 for high-risk answer

Sum by Group (CC/PIFI/HCI), Risk level, or score

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Yikes! Not another Survey

Average survey time: 4 Minutes

2014 Participation Rates by Group

Group Surveyed Responded Pct

Custodial 176 102 58%

Faculty 480 338 70%

Staff 1140 779 68%

Student Employees 2069 1072 52%

Grand Total 3865 2291 59%

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Survey Part 1: What do you handle?

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Survey Part 2: Where do you get it?

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Survey Part 3: Where do you keep it?

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Survey Part 4: What do you do with it?

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Example Score Calculation: PIFI

Sally’s PIFI Score Gets PIFI from 1 low risk place Stores PIFI in 1 low risk place Transmits via 3 ways (1 high risk, 2 low risk) Score is thus 10004 (1x10000+4)

Risk: Measured.

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Risk: Counted.

Risk: Summed.

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Training Directed by REAL Access

Estimated campus-wide training: $2,000/Minute

SANS Security Awareness Summit Dallas, TX | Mon Sep 8 - Wed Sep 17, 2014

Finally!

• Training is directed by access (by department/unit)

• Audits are directed by risk (not reputation)

• Reviews and remediation can be swift

• Risk can be accessed at person, department, division levels
