PENETRATION TESTING

What do you call it?

• Hiring someone to hack your company for good reason.

– Penetration testing

– Tiger teaming

– Intrusion testing

– Ethical hacking

– Vulnerability Analysis

– Even, Security Assessment

Characteristics of Pentesting

• Focusing on tools and technology, and very small potion on methodology

• Interpreting the result

• Protecting the innocent

• Politics and processes

• Testing dangers

2015-07-22 Knowing You're Secure 9

Security = Physics

• Penetration testing is

– the pinnacle of thought-provoking security activity

– Touching on the simplistic nature of security

– The act of exploiting vulnerabilities with good reasons

WHY DO YOU NEED THE PENETRATION TESTING

Hacking Impacts

• Resources

– Core services, object code, disk space …

• Information

– Loss, disclosure and integrity.

• Time

– Anything consumes time will consumes money and will cause the financial loss

• Brand and Reputation

The Hacker

• Hacker leads destruction? Only misuse of term.

• Hacker

– Investigate the workings of computers for fun and a challenge

– Not to penetrate or perform malicious acts

• Cracker

– Break computers to use them for free or use system resources

• What is correct word for the hacker who do malicious act in the present

– Hacker(Cyber Criminal) or Malicious Hacker

Types of Hackers

• Script Kiddies

– Unstructured

– Structured

– Determined

• Independent hackers

– Malicious

– Solvers

– Hacktivist

– Vigilante

• Organized hackers

– State-Sponsored

– Extortion

• Hitman

• Terrorist

– Espionage

Motives

• What Maelstrom said

– I just do it because it makes me feel good, as in better than anything else that I’ve ever experienced.

• What Kevin Mitnick described

– You get a better understanding of cyberspace, the computer systems, the operating systems, how the computer systems interact with on another; that basically was my motivation behind my hacking activity in the past.

– It was just from the gain of knowledge and the thrill of adventure, nothing that was well and truly sinister as trying to get any type of monetary gain or anything

• Six Fundamental drivers for hackers

– Addiction to computers

– Curiosity of the possible

– Excitement

– Social status

– Power

– Betterment of society

HOW DO YOU PERFORM THE PENETRATION TESTING

2015-07-22 Knowing You're Secure 18

Many organization do pentesting every year

• Penetration testing become mainstream

– How many time you do penetration testing to your organization?

– How many different penetration testing team you hire?

– Do you likely ask your pentesting team to do different activities?

– Do you have any idea what they are using for pentesting?

Framework

• What is Framework?

• How does it apply to attacking a system?

• Is a framework a methodology?

Mitigation

Defense

Incident Management

The Software Vulnerability Asymmetry Problem

• Defender must fix all vulnerabilities in all software, but attacker wins by finding and exploiting just one vulnerability

• Threat change over time – state-of-the-art in vulnerability finding and attack technique changes over time.

• Patch deployment takes time – vendor must offset risks to stability & compatibility, customer waits for servicing cycle

Result: Attackers only have to find one vulnerability, and they get to use it for a really long time.

Exploit Economics

ROI = Gain from Investment – Cost of Investment

Cost of Investment

Attacker ROI = Attacker Gain – Attacker Cost

Attacker Cost

Attacker Gain = Gain

Opportunity x N Opportunities

Attacker Cost = Vulnerability Cost + Exploitation Cost

Attacker ROI

Gain

Opportunity x N Opportunities ( ) - Vulnerability Cost + Exploitation Cost ( )

Vulnerability Cost + Exploitation Cost ( ) =

Exploit Economics

• We can decrease Attacker ROI if we are able to…

• Increased attacker investment – increased cost to find usable vulnerabilities

• Varies by platform and vendor and technology

• New tools and automation help w/bug mining, but on some platforms the watermelons are already harvested

• Increased attacker investment required to write reliable (and stealthy) exploits

• Exploit vulnerability and breakout of sandbox / defeat additional protections and mitigations

• Boutique bespoke software development house w / ever expanding requirements

• Decreased attacker opportunity to recover investment

• Fewer opportunities via artificial diversity & improved updating

• Ever improving detection of exploits & follow on actions

• Fewer resale ? Reuse opportunities

Result: Stealthy, reliable attacks require significant engineering; working exploits become more scarce and valuable and shorter lived(?)

Attacker ROI

Opportunity x N Opportunities ( ) - Vulnerability Cost + Exploitation Cost ( )
