According to the vulnerability. the study, businesses are using OSS to improve the quality of their solutions; leverage competitive features and technical capabilities; and customize and maintain their applications by having access to source code. While using open source for operating systems, databases and software development tools has been broadly adopted, numerous vulnerabilities in these platforms are found every year.

Mocana Corporation Copyright 2017 www.mocana.com WHAT IS THE COST TO SUPPORT OPEN SOURCE SECURITY SOFTWARE? While open source software may be free to download, significant costs exist to use, manage and maintain the software during the various stages of software development: development, testing, QA, compliance certification, production and maintenance. While these numbers are purely budgetary, this is based upon research that Mocana has done with its customers and partners that use open source security software. OpenSSL Support Cost Comparison OpenSSL Mocana Pre-purchase Cost Pre-purchase Cost Training Cost $20,000 Training Cost $20,000 Software Development Cost Software Development Cost Total Cost/Year $1,271,000 Total Cost/Year $462,500 Lifecycle Management Cost Lifecycle Management Cost Total Cost/Year $786,000 Total Cost/Year $280,500 Total Cost/Year $2,057,000 Total Cost/Year $743,000 Cost Savings $1,314,000 Training Lifecycle ManAgement Training your development team is Lifecycle management includes the essential to ensure that product ongoing costs to evaluate, test and engineers and software developers get patch up to three OpenSSL CVE up to speed as quickly as possible.

    Black-box security analysis of state machine implementations Joeri de Ruiter 18-03-2019 Agenda 1. Why are state machines interesting? 2. How do we know that the state machine is implemented correctly? 3. What can go wrong if the implementation is incorrect? What are state machines? • Almost every protocol includes some kind of state • State machine is a model of the different states and the transitions between them • When receiving a messages, given the current state: • Decide what action to perform • Which message to respond with • Which state to go the next Why are state machines interesting? • State machines play a very important role in security protocols • For example: • Is the user authenticated? • Did we agree on keys? And if so, which keys? • Are we encrypting our traffic? • Every implementation of a protocol has to include the corresponding state machine • Mistakes can lead to serious security issues! State machine example Confirm transaction Verify PIN 0000 Failed Init Failed Verify PIN 1234 OK Verified Confirm transaction OK State machines in specifications • Often specifications do not explicitly contain a state machine • Mainly explained in lots of prose • Focus usually on happy flow • What to do if protocol flow deviates from this?
