1Solving the US Cyber Challenge: Cyber Quest Skyler OnkenSenior, Brigham Young University – IdahoOnPoint Development Group LLCCEH, Security+, ECSA, CISSP (Associate)Blog:Doing this because if you got the questions wrong, there was no information on what the correct answer is. This is supposed to be learning experience.

11Trivia Question - #5Before the SPF DNS record type was created to address spam, which DNS record type did Sender Policy Framework utilize?MXTXTSRVPTR“Early implementations used TXT records for implementation before the new record type was commonly available in DNS software. Use of TXT records for SPF is intended as a transitional mechanism. However, according to the current RFC, 4408, section 3.1.1, "An SPF-compliant domain name SHOULD have SPF records of both RR (Resource Record) types. A compliant domain name MUST have a record of at least one type," and as such, TXT record use is not deprecated.”example.com. IN TXT "v=spf1 +mx a:colo.example.com/28 -all”example.com.

35Practical Question - #29Which computer used an ARP probe to make sure that the IP address was not already in use?“An ARP probe is an ARP request constructed with an all-zero sender IP address. The term is used in the IPv4 Address Conflict Detection specification (RFC 5227). Before beginning to use an IPv4 address (whether received from manual configuration, DHCP, or some other means), a host implementing this specification must test to see if the address is already in use, by broadcasting ARP probe packets.”

37Outcomes ~800 Took the exam Top 300* Went to Cyber Camp Some with scores as low as 25 attended**Ages 18-50’sStudents and ProfessionalsVarious backgroundsPen TestersIncident HandlersForensic InvestigatorsNetwork/Firewall AdminsThe nature of the cyber quest has improved. The skills required are more well rounded; not just aimed at one specific security related field.*: Some chose not to attend, so slots were then offered to others**: Based upon my personal conversations with participants
38The Gap Between Education and Employment 4 Years2-5 Years6 Months – 10 YearsIndustryPersonal EndeavorsShortage does not need to be as short as seen- Hiring the wrong people. They don’t have the passion NOR the skillset.10 years to develop a group of professionalsAlready working in the indsutryHave a really great connectionWhat causes the black hole?Urgent needNot wanting to invest time and money into trainingWhat is happening in the black hole?Unrelated workCross-Training (good)Building resume to get a jobProblem?Certification based industry, not practical experienceSelf-funding is the only means of trainingEnd State:1) We need to nurture the desire in those who have it right out of school. Without that, it may dwindle and die.2) We are looking at nearly twice the time to develop a sufficiently trained professional workforceEducational Institutions
39Working Models Try Outs/Competitions Development Programs Training For ServiceInternship RecruitmentTry Outs: Like the USCC, see what Lockheed and Booze Allen Hamilton are doingDev Programs: Like the NSA. Doing this in management areas of companies.Training For Service: Mandatory employment or service for training. Already doing this for Military/Gov’t
40Educational Institutions Possible Solutions3 Years3 Years11-3 Years0-2 YearsIndustryTraining For ServiceDevelopment ProgramsWorking Models:Try outs (ex, USCC) – Lockheed, Booze Allen Hamilton, etcDevelopment Programs like the NSATraining for “Service”, will lead to drawing professionals into your company. Can be pickyCould be getting security clearances as wellUpon completion of training, which is essentially an entry position, they will be obligated for employment longer than normalMore competative for your positions since people want to take part of your programs.InternshipsTry OutsEducational Institutions
41Other Conclusions I am not a $ cruncher Nurture vs. Nature Don’t rely upon educational institutesDon’t rely upon other companies or certifications to develop your professionalQuality of professional will save you $ in the long runBetter security professionals will save $ in the long run because of data breaches, etc.
