  1. Telecomm Security John R. Durrett, Ph.D. Fall 2010 Various Security Videos ISQS 3360

  2. Course Overview Why the CISSP Exam Review Web Site Contacting Me Grading

  3. Why In CyberWar, China is Just a Skirmish Sony Rootkit of 2005 Crackers & Open Sources Methods Schneier on Security Security News Portal Current Vulnerabilities

  4. How to Worry About Linux Security(Linux Journal 8/28/06) “Worry about a networked system is good, the trick is to worry about the right things & to act on our worries” Folks you should worry about Weapons you should worry about Vulnerabilities You Should Worry About How to channel worries into constructive action

  5. Folks You Should Worry About Mostly work you way outward, but once in awhile look from cracker's viewpoint Identity Thieves Resource Thieves Malicious Code Vandals Corporate Spies Stalkers Not all crackers are remote: INSIDERS

  6. Weapons You Should Worry About Mid 90's weapon was cracker at PC(or) Direct interaction: attacker – victim Usually correct, sometimes not Today vast majority are automated viruses, trojans and worms botnet: spammers paid per distribution node DdoSers, Phishers Crackers still here but most are “script kiddies”

  7. VulnerabilitiesYou Should Worry About a threat equals an attacker plus some vulnerability If a vulnerability cannot be exploited it does not constitute a risk No such thing as a completely invulnerable system but can lower %

  8. Common types of vulnerabilities Bugs in user-space software (applications) Bugs in system software (kernel, drivers/modules, etc.) Extraneous user accounts Extraneous software (with bugs or sloppy/default settings) Unused security features in applications Unused security features in the OS Gullible users

  9. Recipe to convert worry to action Define system functionSun Tzu: analyze terrain you need to defend Prioritize types of attacks most likely What data/resources most likely target What vulnerabilities give access to #3 How can I lower/remove vulnerability

  10. CISSP International Information Systems Security Consortium (ISC)2 Common Body of Knowledge Ten Domains: created to establish a common communications platform CISSP: NOT THE PURPOSE of THIS COURSE

  11. Ten Domains Security Management Practices Access Control Systems Telecommunications & Network Security Cryptography Security Architecture & Modules Operations Security Applications & Systems Development Business Continuity & Disaster Recovery Law, Investigation & Politics Physical Security

  12. Ch 1: Security Management Practices Basic Security Concepts Policies, Standards, Guidelines, & Procedures Roles played in security management Security Awareness Risk Management Data & Information Classification

  13. Ch 2: Access Control Systems A means of ensuring a system’s C.I.A (Confidentiality, Integrity, & Availability) given the threats, vulnerabilities, & risks its infrastructure

  14. Ch 3 :Telecommunications & Network Security C.I.A. as it applies to Network Security Protocols & Layered Network Architectures OSI and TCP/IP TCP/IP protocol architecture IP addressing & Routing TCP Applications IPv6

  15. Ch 4 : Cryptography Purpose: to protect transmitted information from being read or altered by non authorized subjects

  16. Ch 5 : Security Architecture & Models “The security architecture of an information system is fundamental to enforcing an organization’s information security policy.”

  17. Ch 6 : Operations Security “Controls over the hardware in a computing facility, over the data media used, and over the operators using these resources.” Controls & Protections needed to insure CIA Monitoring & Auditing above Controls Threats & Vulnerabilities

  18. Ch 7 :Application & System Development A very brief overview of the SDLC and the security issues involved. Generic Systems Engineering Waterfall Model, Spiral Model Cost Estimations Models Security Components of the Models Agile Development, AI Systems Database, BI, & Application Controls

  19. Ch 8 : Business Continuity & Disaster Recovery Planning Assumes the Worst Has Happened Preparation, testing, & updating of actions required to protect critical business processes from the effects of major system & network failures Buss Continuity (BCP) Disaster Recovery (DRP) Plan initiation Planning Bus. Impact Assess. (BIA) Testing Plan Development Specific Procedures

  20. Ch 9 : Law, Investigation, & Ethics What laws apply to computer crimes, how to determine a crime has occurred, how to preserve evidenced, conduct an investigation, & what are the liabilities.

  21. Ch 10: Physical Security “Least sexy of the 10 domains but the best firewall in the world will not stand up to a well placed brick.” Addresses threats, vulnerabilities, countermeasures to physically protect org’s resources & sensitive info Natural disasters Unauthorized entry and/or theft
