Homeland Open Security Technology

Homeland Open Security Technology is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Homeland Open Security Technology rather than just read about it. In short: Homeland Open Security Technology (HOST) was a five-year, $10 million program by the Department of Homeland Security's Science and Technology Directorate to promote the creation and use of open security and open-source software in the United States government and military, especially in areas pertaining to computer security, established in 2011.

Key takeaways

Homeland Open Security Technology belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Homeland Open Security Technology to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Homeland Open Security Technology from memory before moving on to harder problems.

Reference excerpt

Homeland Open Security Technology (HOST) was a five-year, $10 million program by the Department of Homeland Security's Science and Technology Directorate to promote the creation and use of open security and open-source software in the United States government and military, especially in areas pertaining to computer security, established in 2011. Proponent David A. Wheeler said that open-source security could also extend to hardware and written documents. In October 2011, the project won the Open Source for America 2011 Government Deployment Open Source Award.

Participants The project is contracted to the Open Technology Research Consortium which consists of the Georgia Tech Research Institute (primary), the Center for Agile Technology at the University of Texas at Austin, the Open Source Software Institute, and the Open Information Security Foundation. The project has contributed funding towards the OpenSSL Software Foundation and the Open Information Security Foundation.

Events In October 2012, HOST hosted the Open Cybersecurity Summit in Washington, D.C.; it was a one-day summit with a keynote by Stewart A. Baker, former Assistant Secretary for Policy of the Department of Homeland Security.

Investments Suricata - An open source-based intrusion detection system (IDS). It was developed by the Open Information Security Foundation (OISF). A beta version was released in December 2009, with the first standard release following in July 2010. OpenSSL FIPS 140-2 Validation - The Federal Information Processing Standard (FIPS) Publication 140-2, FIPS PUB 140-2, is a U.S. government computer security standard used to accredit cryptographic modules. The title is Security Requirements for Cryptographic Modules. Initial publication was on May 25, 2001 and was last updated December 3, 2002.

Worked examples

Example 1 — a first encounter with Homeland Open Security Technology

Start with the simplest possible case. Write down what Homeland Open Security Technology claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Homeland Open Security Technology before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Homeland Open Security Technology ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Homeland Open Security Technology

In research: Homeland Open Security Technology appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Homeland Open Security Technology in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Homeland Open Security Technology is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2011 in computing, Computer security in the United States, Georgia Tech Research Institute, so understanding it makes those chapters shorter.
In everyday life: Look for Homeland Open Security Technology outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
