The Information Security Problem
Over the last couple of decades, our world has rapidly become very dependent on computers: Store medical information Guide aircrafts Handle the majority of financial transactions There are flaws in our computers’: Operating systems Applications Protocols Result: threats
9
Exacerbating the Problem
The problem of how to design secure OSs, applications, and protocols is hard Too few security professionals Many users do not understand the magnitude of the threat Many managers do not understand the magnitude of the threat
10
Threats A threat is a potential violation of system security
Examples (from Shirey): Disclosure – unauthorized access to information Deception – acceptance of false data Disruption – interruption or prevention of correct operation Usurpation – unauthorized control of some part of the system
11
Attackers Those who intentionally perform actions that cause security violations Outsiders: Competitors Hackers Organized crime Terrorists Foreign government, military, or law enforcement Insiders Customers, suppliers, vendors, or business partners Disgruntled current (or former) employees Contractors, temps, or consultants
12
Types of Attackers Third tier Second tier First tier
“Script kiddies” with little knowledge or skill Run attack scripts and other software written by more sophisticated attackers Second tier Moderately knowledgeable and skilled attackers Discover vulnerabilities; create and disseminate exploit tools First tier Elite attackers Discover vulnerabilities; create private tools
13
Why You Should Not Be an Attacker
It is illegal: United States Code, Title 18, Section 1030 (and others) USA Patriot Act, Homeland Security Act, PROTECT Act Basically: Unauthorized access or use of a computer or network system is illegal Unintentional attacks are illegal too
14
Understanding the Tools and Techniques of Attackers
Important for defenders Can evaluate systems you defend as attackers will Can implement countermeasures designed to thwart attackers Better understand the implications of certain decisions
15
The Pillars of Computer Security
The security “triad”: Confidentiality Integrity Availability
16
The Security Triad Which is most important? Confidentiality Integrity
Availability
17
Policy and Mechanism A security policy is a statement of what is, and what is not, allowed Examples? A security mechanism is a method, tool, or procedure for enforcing a security policy
18
Goals of Security Prevention – mechanism(s) that cause attacks to fail
Example? Detection – mechanism(s) that determines that an attack is under way, or has occurred, and reports it Recovery – mechanism(s) that stop attacks and assess and repair any damage caused
19
Justifying Policy and Mechanism
The benefits of protection should be justified by the cost of designing, implementing, and using the mechanism Cost-benefit analysis – the benefits of computer security is weighed against the cost Risk analysis – the level of protection is a function of the probability of an attack occurring and the effect of the attack should it succeed Laws and customs
20
Getting Started What to do first? Get to know you systems
You cannot effectively defend what you don't understand Attackers make it their job to understand systems better than the defenders and leverage their advantage in knowledge “If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle” - Sun Tzu

If you know neither the enemy nor yourself, you will succumb in every battle” - Sun Tzu “You Don't Know Me” - Elvis
22
After You Know Your Systems
Think about threats and attackers Think about what needs to be protected (security triad) Think about what security policies and mechanisms you will employ Think about your goals (prevention, detection, recovery) Think about how what policies and mechanisms are justified
23
After You Have Thought About Your Systems
Start to plan, implement, and test improvements to your systems' security posture Respond to actions by attackers
24
Getting started Defending Computer Systems
Get to know your systems Assess the current security posture of your systems Identify what needs to be protected Think about how threats, attackers, the security triad, security policies/mechanisms, and security goals relate to your systems Plan, implement, and test improvements to your systems' security posture
25
Bootcamp Exercises You will not just be listening, you will be doing
Virtual machines (VMs) – a simulated computer running on another computer VMs are great for hands-on Cyber Defense exercises You can create and use VMs with your students using free software: VirtualBox ( VMWare Player (
26
Accessing your VM for this Bootcamp
Turn on laptop Click on “CyberDefender” account to log in Double click on Firefox icon to open web browser Enter this information in the vSphere If you are not already on it, go to the following page:
27
Accessing your VM for this Bootcamp (cont)
Log in with the credentials you were given Click on “Host and Clusters” Expand the items on the left side until you see your “student” VM Click on your student VM to highlight it In the center window click on the “Summary” tab Click on “Launch Console” Power on the VM
