Seven Recommendations for Testing in a Non-Deterministic World

Seven Recommendations for Testing in a Non-Deterministic World

• SEI Blog
Donald Firesmith

In a previous post, I addressed the testing challenges posed by non-deterministic systems and software such as the fact that the same test can have different results when repeated. While there is no single panacea for eliminating these challenges, this blog posting describes a number of measures that have proved useful when testing non-deterministic systems....

CERT C++ Secure Coding Guidelines

CERT C++ Secure Coding Guidelines

• SEI Blog
David Svoboda

Software vulnerabilities typically cost organizations an average of $300,000 per security incident. Efforts aimed at eliminating software vulnerabilities must focus on secure coding, preventing the vulnerabilities from being deployed into production code. "Between 2010 and 2015, buffer overflows accounted for between 10-16% of publicly reported security vulnerabilities in the U.S. National Vulnerability Database each year," Microsoft researcher David Narditi wrote in a recent report. In March, the Secure Coding Team in the SEI's CERT Division...

Best Practices for NTP Services

Best Practices for NTP Services

• SEI Blog
Timur Snoke

The network time protocol (NTP) synchronizes the time of a computer client or server to another server or within a few milliseconds of Coordinated Universal Time (UTC). NTP servers, long considered a foundational service of the Internet, have more recently been used to amplify large-scale Distributed Denial of Service (DDoS) attacks. While 2016 did not see a noticeable uptick in the frequency of DDoS attacks, the last 12 months have witnessed some of the largest...

Three Practice Areas for Using Positive Incentives to Reduce Insider Threat

Three Practice Areas for Using Positive Incentives to Reduce Insider Threat

• SEI Blog
Andrew Moore

In the 2016 Cyber Security Intelligence Index, IBM found that 60 percent of all cyber attacks were carried out by insiders. One reason that insider threat remains so problematic is that organizations typically respond to these threats with negative technical incentives, such as practices that monitor employee behavior, detect and punish misbehavior, and otherwise try to force employees to act in the best interest of the organization. In contrast, this blog post highlights results from...

Combined Arms Cyber-Kinetic Operator Training

Combined Arms Cyber-Kinetic Operator Training

• SEI Blog
Rotem Guttman

As cyber-physical systems continue to proliferate, the ability of cyber operators to support armed engagements (kinetic missions) will be critical for the Department of Defense (DoD) to maintain a technological advantage over adversaries. However, current training for cyber operators focuses entirely on the cyber aspect of operations and ignores the realities and constraints of supporting a larger mission. Similarly, kinetic operators largely think of cyber capabilities as a strategic, rather than a tactical resource, and...

Experiences Using IBM Watson in Software Assurance

• SEI Blog
Mark Sherman

Since its debut on Jeopardy in 2011, IBM's Watson has generated a lot of interest in potential applications across many industries. I recently led a research team investigating whether the Department of Defense (DoD) could use Watson to improve software assurance and help acquisition professionals assemble and review relevant evidence from documents. As this blog post describes, our work examined whether typical developers could build an IBM Watson application to support an assurance review....

Distributed denial-of-service (DDoS) attacks have been dominating the IT security headlines. A flurry of reporting followed the September 2016 attack on the computer security reporter Brian Krebs's web site KrebsonSecurity when he reported attack traffic that was at the unprecedented scale of gigabytes per second. In November, my colleague Rachel Kartch wrote "DDOS Attacks: Four Best Practices for Prevention and Response," outlining what we can do to defend against these attacks. In this blog post,...
