Effective cybersecurity engineering requires the integration of security into the software acquisition and development lifecycle. For engineering to address security effectively, requirements that establish the target goal for security must be in place. Risk management must include identification of possible threats and vulnerabilities within the system, along with the ways to accept or address them. There will always be cyber security risk, but engineers, managers, and organizations must be abl...

Dynamic network defense (or moving target defense) is based on a simple premise: a moving target is harder to attack than a stationary target. In recent years the government has invested substantially into moving target and adaptive cyber defense. This rapidly growing field has seen recent developments of many new technologies—defenses that range from shuffling of client-to-server assignments to protect against distributed denial-of-service (DDoS) attacks, to packet header rewriting, to rebootin...

To ensure software will function as intended and is free of vulnerabilities (aka software assurance), software engineers must consider security early in the lifecycle, when the system is being designed and architected. Recent research on vulnerabilities supports this claim: Nearly half the weaknesses identified in the Common Weakness Enumeration (CWE) repository have been identified as design weaknesses. These weaknesses are introduced early in the lifecycle and cannot be patched away in later p...

Safety-critical software must be analyzed and checked carefully. Each potential error, failure, or defect must be considered and evaluated before you release a new product. For example, if you are producing a quadcopter drone, you would like to know the probability of engine failure to evaluate the system's reliability. Safety analysis is hard. Standards such as ARP4761 mandate several analyses, such as Functional Hazard Assessment and Failure Mode and Effect Analysis. One popular type of safety...

Due to advances in hardware and software technologies, Department of Defense (DoD) systems today are highly capable and complex. However, they also face increasing scale, computation, and security challenges. Compounding these challenges, DoD systems were historically designed using stove-piped architectures that lock the government into a small number of system integrators, each devising proprietary point solutions that are expensive to develop and sustain over the lifecycle. Although these sto...

The Department of Defense (DoD) must focus on sustaining legacy weapons systems that are no longer in production, but are expected to remain a key component of our defense capability for decades to come. Despite the fact that these legacy systems are no longer in the acquisition phase, software upgrade cycles are needed to refresh their capabilities every 18 to 24 months. In addition, significant modernization can often be made by more extensive, focused software upgrades with relatively modest ...

We know from existing SEI work on attribute-driven design, Quality Attribute Workshops, and the Architecture Tradeoff Analysis Method that a focus on quality attributes prevents costly rework. Such a long-term perspective, however, can be hard to maintain in a high-tempo, agile delivery model, which is why the SEI continues to recommend an architecture-centric engineering approach, regardless of the software methodology chosen. As part of our work in value-driven incremental delivery, we conduct...

Whether Java is more secure than C is a simple question to ask, but a hard question to answer well. When researchers on the CERT Secure Coding Team began writing the SEI CERT Oracle Coding Standard for Java, they thought that Java would require fewer secure coding rules than the SEI CERT C Coding Standard because Java was designed with security in mind. They also assumed that a more secure language would need fewer rules than a less secure one. However, Java has 168 coding rules compared to just...

In our studies of many large-scale software systems, we have observed that defective files seldom exist alone. They are usually architecturally connected, and their architectural structures exhibit significant design flaws that propagate bugginess among files. We call these flawed structures the architecture roots, a type of technical debt that incurs high maintenance penalties. Removing the architecture roots of bugginess requires refactoring, but the benefits of refactoring have historically b...

The Building Security In Maturity Model (BSIMM) is the result of a multi-year study of real-world software security initiatives. It is built directly from data observed in 78 software security initiatives from firms in nine market sectors. The best way to use the BSIMM is to compare and contrast your own initiative with the data about what other organizations are doing as described in the model. You can then identify goals and objectives and refer to the BSIMM to determine which additional activ...

In their haste to deliver software capabilities, developers sometimes engage in less-than-optimal coding practices. If not addressed, these shortcuts can ultimately yield unexpected rework costs that offset the benefits of rapid delivery. Technical debt conceptualizes the tradeoff between the short-term benefits of rapid delivery and long-term value. Taking shortcuts to expedite the delivery of features in the short term incurs technical debt, analogous to financial debt, that must be paid off l...
