• Critical Infrastructure security
• Security Testing for OT
• Conclusions
3 IBM Security
Who are X-Force Red ?
§ IBM X-Force Red is an elite, global team of over 100 consultants providing security testing services to organizations of all sizes
§ X-Force Red can perform expert testing of ANY technology everything from Oil&Gas, Nuclear Power Stations to embedded Electronic components as well as usual Network, System, Web Application and Mobile Testing
§ Consultants in IBM X-Force Red are widely considered industry leaders, having spoken at high-profile events like RSA, Black Hat, DEF CON, and other international conferences.
§ Easy mode of working from one off engagements to a subscription model.
4 IBM Security
Every OT environment has its specific security requirements
https://en.wikipedia.org
• Il tipo di architettura influenza gli scenari di attacco e in generale la sicurezza dei sistemi OT
• E’ fondamentale comprendere il funzionamento e le modalita’ operative dell’impianto

OT Security analysis strategy
Sistemi “fragili” in produzione
Sistemi proprietari
Architetture e modelli operativi complessi
Le modifiche o aggiornamenti spesso non sono consentiti
Challenges
OT testing strategy
OT Testing skills
Threat modeling
Collaborazione con i Vendor
Approach

Obiettivi
Ø Identificare gli scenari di attacco rilevanti
Ø Verifiare gli scenari di attacco possibili
Ø Verificare il livello di “Security Visibility”
Ø Selezionare le contromisure adatte
Metodologia
Ø Threat Modeling/Attack Scenarios driven
Ø OT Test strategy/Test Cases Engineering
Ø Vulnerabilita’ – Scenari di attacco mapping
8 IBM Security
Common OT Analysis Findings
• No or limited inventory
• Vulnerable to Ransomware attacks type
• Weak protocols leave systems vulnerable
• Wireless devices left by techs who want to sit in the truck.
• OT networks lack overall segmentation
• Most IP-based communications along the pipeline are not encrypted
• Emergency response not adequate
• Limited control over the vendors security configurations
• Lack of cyber security awareness
• Most IP-based communications along the pipeline are not encrypted
• No logging on OT systems, even if available
• No accountability on systems access
• OT systems left default and not hardened
• No security monitoring in OT
• Weak security policies on Plant IT equipment.
• Inadequate physical security (distribution networks)

Improper access can result in information being altered, destroyed, misappropriated or misused or can result in damage to or misuse of your systems, including for use in attacks on others. No IT system or product should be considered completely secure and no single product, service or security measure can be completely effective in preventing improper use or access.
