A breakdown of topics is presented for the knowledge area along with a succinct description of each topic. References are given to materials that provide more in-depth coverage of the key areas of software configuration management. Important...

Defeating Cross-Site Request Forgery Attacks with Browser-Enforced Authenticity Protection

A cross site request forgery (CSRF) attack occurs when a user’s web browser is instructed by a malicious webpage to send a request to a vulnerable web site, resulting in the vulnerable web site performing actions not intended by the user. CSRF vulnerabilities are very common, and consequences of such attacks are most serious with financial websites. We recognize that CSRF attacks are an example...

A Robust Strucutural Fingerprint Restoration

Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...

A Robuster Scott Rank

We give a new definition of Scott rank motivated by our main theorem: For every countable structure A and ordinal α < ω1, we have that: every automorphism orbit is Σ α -definable without parameters if and only if A has a Π α+1 Scott sentence, if and only if A is uniformly boldface ∆α-categorical. As a corollary, we show that a structure is computably categorical on a cone if and only if it is t...
