Harris Corp. [HRS] last week said it has acquired Crucial Security, Inc., a small information technology firm that has offensive and defensive capabilities in cyber warfare.

Terms of the deal were not disclosed. Crucial Security, which is based in Northern Virginia, has 110 employees.

Crucial Security’s core competencies include enabling customers to launch attacks against their own systems to determine network vulnerabilities; defense against outside attacks using technology such as malicious code reverse engineering to determine the functionality of hostile programs; computer forensics for extracting and examining counter- intelligence and counter-terrorism evidence that may be stored on captured hard drives or digital media; and predictive capabilities that allow for large-scale, high-speed bulk analysis, visualization and graphic display of mission critical data.

Harris said the deal expands capabilities and customer base in cyber security.

“Crucial Security’s deep understanding of both offensive and defensive cyber security, unparalleled software engineering domain expertise, and immensely talented employees, most of whom have high-level security clearances, add significantly to our current initiatives in the fast growing cyber security market,” Howard Lance, Harris’ chairman, president and CEO, said in a statement. “With this acquisition and the recent hiring of Dale Meyerrose, the former chief information officer for the Intelligence Community, we have greatly expanded our leadership and expertise in cyber and information assurance.”

Crucial Security’s customers include federal law enforcement and intelligence agencies.
