Deep Learning and Satellite Imagery: DIUx Xview Challenge

• SEI Blog
Ritwik Gupta

In 2017 and 2018, the United States witnessed a milestone year of climate and weather-related disasters from droughts and wildfires to cyclones and hurricanes. Increasingly, satellites are playing an important role in helping emergency responders assess the damage of a weather event and find victims in its aftermath. Most recently satellites have tracked the devastation wrought by the California wildfires from space. The United States military, which is often the first on the scene of...

Improving Assessments for Cybersecurity Training

April Galyardt

The CERT Cyber Workforce Development Directorate conducts training in cyber operations for the DoD and other government customers as part of its commitment to strengthen the nation's cybersecurity workforce. A part of this work is to develop capabilities that better enable DoD cyber forces to "to train as you fight" such as setting up high-fidelity simulation environments for cyber forces to practice skills including network defense, incident response, digital forensics, etc. However, cybersecurity is a...

Governance of a Software Product Line: Complexities and Goals

Governance of a Software Product Line: Complexities and Goals

• SEI Blog
Robert Ferguson

My prior blog post on product lines in DoD sustainment described the complexity of contractual relationships in a DoD software product line. Recall that a software product line is a collection of related products with shared software artifacts and engineering services that has been developed by a single organization in support of multiple programs serving multiple missions and different customers. A product line can reduce cost of development and support. In exchange, it can be...

SCALe v. 3: Automated Classification and Advanced Prioritization of Static Analysis Alerts

SCALe v. 3: Automated Classification and Advanced Prioritization of Static Analysis Alerts

• SEI Blog
Lori Flynn

This post was co-authored by Ebonie McNeil. Static analysis tools analyze code without executing it, to identify potential flaws in source code. These tools produce a large number of alerts with high false-positive rates that an engineer must painstakingly examine to find legitimate flaws. As described in Lori's first blog post on this topic, we in the SEI's CERT Division have developed the SCALe (Source Code Analysis Laboratory) tool since 2010 as part of our...

Jeffrey Gennari

In a previous post, I discussed the Pharos Binary Analysis Framework and tools to support reverse engineering of binaries with a focus on malicious code analysis. Recall that Pharos is a framework created by our CERT team that builds upon the ROSE compiler infrastructure developed by Lawrence Livermore National Laboratory. ROSE provides a number of facilities for binary analysis including disassembly, control flow analysis, instruction semantics, and more. Pharos uses these features to automate common...

Threat Modeling: 12 Available Methods

Threat Modeling: 12 Available Methods

• SEI Blog
Nataliya Shevchenko

Almost all software systems today face a variety of threats, and the number of threats grows as technology changes. Malware that exploits software vulnerabilities grew 151 percent in the second quarter of 2018, and cyber-crime damage costs are estimated to reach $6 trillion annually by 2021. Threats can come from outside or within organizations, and they can have devastating consequences. Attacks can disable systems entirely or lead to the leaking of sensitive information, which would...

Rapid Software Composition by Assessing Untrusted Components

Rapid Software Composition by Assessing Untrusted Components

• SEI Blog
Rick Kazman

Today, organizations build applications on top of existing platforms, frameworks, components, and tools; no one constructs software from scratch. Hence today's software development paradigm challenges developers to build trusted systems that include increasing numbers of largely untrusted components. Bad decisions are easy to make and have significant long-term consequences. For example, decisions based on outdated knowledge or documentation, or skewed to one criterion (such as performance) may lead to substantial quality problems, security risks, and...
