As we progress through our threat models with the corresponding assignments, I have come to realize that we are only scratching the surface of threat modeling. The Harry and Mae's case study has so many unknown variables that would normally be addressed in a real environment, and consequently gets left out of the assignments. Some of the known variables are generic descriptions, and we have to make assumptions in order to give a proper analysis.
In any case, I feel threat modeling requires much more time to solicit information, document the environment, investigate specific threats and vulnerabilities, calculate the risks, provide more detailed recommendations, and identify metrics for defining success. As students (most of us with full-time jobs), we have limited time to completely cover all aspects, and I have noticed some scope shrinkage in order to demonstrate that we understand the basic concept of the assignments.
It seems that a comprehensive threat analysis would require a diverse team of security consultants working with the in-house network engineers, system admins, and project managers over a span of weeks to encompass everything that would benefit from a security makeover. As a result, I have a much deeper appreciation for the opportunity to learn this process, and for the experts who carry this out on a daily basis.

CYBR 650 Week 7 – Threat Analysis
This week has been a bit of a challenge in class, as we apply our threat models to a case study. So far, we have created our own threat process models, identified credible sources to stay current, and analyzed the fictitious system in the case study.
Now we are in the threat analysis stage, which means that we have to use the resources we identified earlier in the process to enumerate the business assets, their vulnerabilities, the imposing threats and threat types, and assess the risk to the environment. While there are many ways to demonstrate the relationship between all four elements, a simple Venn diagram seems to illustrate this nicely:

While this assignment proved to be a lot of work researching the material, it was also probably the most rewarding. I was very impressed by the pot of gold I found in NIST's National Vulnerability Database by using just a few keywords that applied to the case study. However, this is only a repository for hardware, firmware, or software weaknesses. Since processes are usually unique to an organization, finding process vulnerabilities will require a supplemental assessment.

CYBR 650 Week 6 – Women in IT Security

This week I had the privilege of attending the annual ICAN Women's Leadership Conference. The theme this year focused on women balancing work and life, which has been a decades-long struggle while we are still trying to break out of traditional gender roles.
Michael Kimmel, Professor of Sociology & Gender Studies at Stony Brook University, gave one of the most interesting key note presentations on the main stage: The Gendered Society. He stated, "Research by Catalyst and others has shown conclusively that the more gender-equal companies are, the better it is for workers, the happier their labor force is. They have lower job turnover. They have lower levels of attrition. They have an easier time recruiting. They have higher rates of retention, higher job satisfaction, higher rates of productivity."
What does this mean for cybersecurity? Kimmel pondered why there are so few women at the top of STEM careers. His theory is that due to the expectations placed on women within the home, many women are simply unable or unwilling to dedicate the time and effort it takes to advance in a male dominated field. The statistics for women in cybersecurity are staggering:
So what needs to be done to level the playing field? Please leave your comments below.

CYBR 650 Week 5 - TechJunction 2016
I recently had the opportunity to be on the advisory committee for TechJuncion 2016, a technology conference geared towards security and server management. It is hosted annually right here in the heartland of America, and the best part is that it's free to attend! Here are some of the highlights:
Passwords Suck: A Platform Approach To Securing Enterprise Identities
Presented by: Centrify
This presentation advocated single sign-on software. Statistics for password theft show that 63% of breaches were due to compromised accounts.
Ransomware: All Locked Up With No Place To Go
Presented by: Kaspersky Lab
Kaspersky Labs outlined how businesses can protect themselves against ransomware through backups, updates, and anti-virus programs. Kaspersky offers System Watcher and Automatic Exploit Prevention as security tools to prevent against ransomware. Current statistics of ransomware are available in Verizon's 2016 Data Breach Investigations Report - see below for the link.
Defending Against Modern Malware
Presented by: WatchGuard Technologies, Inc.
WatchGuard delivered a sobering speech about modern malware. They stated that modern malware is moving from signatures to binary patterns. For example, ransomware uses bitcoins for payment, and is almost impossible to track. They also identified three different cyber attacker profiles: Hacktivist, Cyber Criminal, and Nation State. The good news is there are websites that monitor attacks and breaches (see Other Websites section below), and WatchGuard has designed a solution to break the Cyber Kill Chain (see their PDF presentation below).
Why Do You Need DR?
Presented by: Zerto, Inc.
Zerto started the presentation by pointing out that disasters are both natural and operational. Disaster recovery planning should include backup, redundancy, impact/urgency considerations, and should turn a disaster into a non-event.
Innovation Matters
Presented by: SimpliVity
Simplivity defined innovation as a means to improve on a service based on current needs. They used Netflix as an example of how they capitalized on Blockbuster's current movie rental service by catering to current and future business trends, and changing the way the service is delivered.
Hyperconvergence is today's way of innovating by combining several functions into one delivery method. An example of hyperconvergence is how phones evolved from just a device to make calls, to smart phones, which can browse the web, track fitness goals, display the current weather, and so much more. Hyperconvergence allows us to virtualize server, data, network resources to optimize delivery and reduce duplication.
Keynote Presentation: Surviving Security Groundhog Day
Presented by Ron Woerner • Director & Professor, Cybersecurity Studies at Bellevue University
This speaker deserves special accolades, as he has been the driving force behind my pursuit of a Master's degree in Cybersecurity. Prof. Woerner indicated that technology has advanced to IoT (Internet of Things), but security isn't getting any better. Humans are still the weakest link, and complacency is a big culprit. He reassured the attendees that security never has to be 100%, just good enough, but you need to have an iron-clad contract for cloud services to be secure. His motto: If you SEE something, SAY something!
Thanks for all you do, Coach.

CYBR 650 Week 4 - Attack Trees
Attack Trees
Attack trees appeared in the 1990's as an attacker-centric approach to analyze the security of systems. Usually displayed as a Visio flow chart, it diagrams possible attacks against an object. The parent node represents the goal, while child nodes break out the various methods to achieve the goal, as illustrated in this example:

The parent node represents the goal, while child nodes break out the various methods to achieve the goal, as illustrated in this example:
Introduced by Bruce Schneier, attack trees can also assign values, such as difficulty, cost, intrusiveness, legality, or just about any other metric that might tell a security story. For example, if the method to achieve the goal costs more than the goal itself, the probability of the attack is less likely. Security teams can use this information to make recommendations and implement controls as necessary.
This type of threat modeling may seem time-consuming and rebellious to the software-centric approach to the Microsoft's Security Development Lifecycle, but it has some versatility. Once the attack tree is fully grown, it can be linked to other trees so analysts or developers can see the forest. And according to Schneier, “If you're a computer-security expert, you don't have to know the details about how difficult a particular model of safe is to crack; you just need to know the values of the root node.”
What do you think? Is this approach outdated or still useful? Please post your comments below.

CYBR 650 Week 2 - Credible Sources for Information Security
With any type of research, it is critical to have references
in your arsenal to ensure the information is complete, accurate, and comes from
a reputable source. Threat modeling is no different, and some of my favorites
for reporting on threats, vulnerabilities, updates, and security news
are listed below:
- SOPHOS’ nakedsecurity - http://nakedsecurity.sophos.com/ - I use this site a lot because it covers security for a variety of platforms, most notably Macs. I am a Mac user myself, and it is beneficial to have someone on the IT staff that can provide expertise in this area. Despite popular belief, Apple products are not immune to attacks, and this is one website that delivers great information for securing Apple devices. They also provide a section that focuses on vulnerabilities in general at http://nakedsecurity.sophos.com/category/security-threats/vulnerability/.
- TechTarget’s SearchSecurity - http://searchsecurity.techtarget.com/resources#parentTopic4 - Tech Target is a great news source for any topic related to IT, but SearchSecurity also includes an area specially designed for information security threats. It covers several types of threats, hacking tools and techniques, security awareness training, and more.
- SANS @Risk: The Consensus Security Alert - http://www.sans.org/newsletters/risk/ - This newsletter gives a synopsis of the top vulnerabilities each week, with a complete listing of all new vulnerabilities. While anyone can just browse the archives, subscribers also receive SANS Flash Alerts several times per year.
- Forbes - http://www.forbes.com/security/ - Forbes is not just a financial resource anymore. It has expanded its horizons to encompass technology. Security is listed as a sub-topic under technology, and the authors do a great job of keeping up with current security trends.
- NIST’s National Vulnerability Database - http://nvd.nist.gov/ - Last but not least, this website hosts the Vulnerability Search Engine to query common configuration enumeration (CCE) or common vulnerabilities and exposures (CVE) for any type of software contained in the database. It also has a repository of security checklists based on accepted standards for organizations to use as a benchmark for securing their own systems.
Additionally, CSO Online provides a one-stop-shop dashboard of valuable security tools and information, located at http://www.csoonline.com/article/2926005/techology-business/cso-online-daily-dashboard.html.
While all of these sources have a proven track record for reliability and trustworthiness, experts are not always going to agree. One course of action is to go with the majority for any conflicting information. More knowledgeable individuals can go a step further and use these resources to develop their own analysis.

CYBR 650 Week 1 - Introduction
Welcome back! For my final class in the Master of Cybersecurity program, our task is to create our own threat process model using Visio to map it out. This blog will follow my efforts.
During some basic research on this topic, I came across Microsoft's SDL Threat Modeling Tool. It requires Visio to run, and it aids in analyzing threats for this particular endeavor. Since I need to have Visio installed anyway, and the SDL Threat Modeling Tool is free, my goal is to incorporate it into the assignments and post evaluations of the tool along the way.
