Abstract
The following section describes the tools we built to test the utilities. These tools include the fuzz (random character) generator, ptyjig (to test interactive utilities), and scripts to automate the testing process. Next, we will describe the tests we performed, giving the types of input we presented to the utilities. Results from the tests will follow along with an analysis of the results, including identification and classification of the program bugs that caused the crashes. The final section presents concluding remarks, including suggestions for avoiding the types of problems detected by our study and some commentary on the bugs we found. We include an Appendix with the user manual pages for fuzz and ptyjig.

Cyber Wars: A Paradigm Shift from Means to Ends

Amit Sharma
- 04 Feb 2010 - 
TL;DR: In this paper, the authors tried to illuminate the strategic aspects of this relatively misinterpreted notion, thus identifying a paradigm shift, making cyber war the primary means of achieving grand strategic objectives in the contemporary world order.

Vulnerability Testing of Software System Using Fault Injection

TL;DR: This work describes an approach for testing a software system for possible security flaws and presents a security-flaw classification scheme based on an Environment-Application Interaction (EAI) fault model, which was used to classify 142 security flaws in a vulnerability database.

Operational profile specification, test case generation, and reliability estimation for modules

TL;DR: This thesis explores both practical and theoretical problems associated with module reliability estimation, and presents a method for estimating module reliability, based on statistical hypothesis testing.

Adaptive random testing through iterative partitioning

TL;DR: In this article, the authors proposed the notion of iterative partitioning to reduce the amount of the computation while retaining a high fault-detection capability, and the cost effectiveness of ART has been improved.

QuickFuzz: an automatic random fuzzer for common file formats

TL;DR: QuickFuzz is a fuzzer that leverages QuickCheck-style random test-case generation to automatically test programs that manipulate common file formats by fuzzing, and introduces a mechanism to automatically derive random generators for the types representing these formats.

On the criteria to be used in decomposing systems into modules

TL;DR: In this paper, the authors discuss modularization as a mechanism for improving the flexibility and comprehensibility of a system while allowing the shortening of its development time, and the effectiveness of modularization is dependent upon the criteria used in dividing the system into modules.

Letters to the editor: go to statement considered harmful

TL;DR: My considerations are that, although the programmer's activity ends when he has constructed a correct program, the process taking place under control of his program is the true subject matter of his activity, and that his intellectual powers are rather geared to master static relations and his powers to visualize processes evolving in time are relatively poorly developed.

Go to statement considered harmful

TL;DR: In form and content, Dijkstra's letter is similar to his 1965 paper, and the last few paragraphs underscore once again why the subject of structured programming stayed out of the mainstream of the data processing industry for so long.

Efficient learning of context-free grammars from positive structural examples

TL;DR: It is shown that the class of reversible context-free grammars can be identified in the limit frompositive samples of structural descriptions and there exists an efficient algorithm to identify them from positive samples ofStructural descriptions, where a structural description of a context- free grammar is an unlabelled derivation tree of the grammar.

Crisis and aftermath

TL;DR: Last November the Internet was infected with a worm program that eventually spread to thousands of machines, disrupting normal activities and Internet connectivity for many days.
