(Spoofing, Tampering, Repudiation, Information, Denial, Elevation) An acronym for remembering six areas of risk in technology. For an excellent example of applying STRIDE to Web applications, visit the keepers of the Open Web Application Security Project (OWASP) at

Spoofing Identities
A user should not be able to assume the identity of, or mask the attributes of, someone else. Using a public key infrastructure (PKI) and digital signatures is a way of preventing spoofing.

Tampering With Data
The integrity of data should be preserved at all times. Encryption, independent verification and input, process and output validation are some of the tools that can be used.

Repudiate a Transaction
A valid transaction should not be subject to rejection. Good audit trails and signing a message with date and time are examples of preventative methods.

Information Disclosure
Information should not fall into unauthorized hands. Data loss prevention (DLP) techniques are used to strengthen corporate confidentiality. See DLP.

Denial of Service
A server or an application should not be vulnerable to being put out of service. Redundant and/or backup systems are datacenter architectures that can be used.

Elevation of Privilege
An unauthorized user should not be allowed administrator rights. Refusing to share passwords or tokens can reduce this risk. See access control.

Rey's playing combines country blues, stride piano, classic jazz and hillbilly boogie through the sensibility of "an autodidact trailer park esthete," a news release says.
The presence of key recording studios and the Harlem tradition of stride piano (and organized representation spearheaded by leaders like James Reese Europe, as documented in Reid Badger's recently published A Life in Ragtime, Oxford) helped spawn New York's rep as jazz's Big Apple.
In describing Powell's idiosyncratic approach to the piano, Ramsey introduces the interesting neologism, "againstness." Instead of relying upon the solid rhythmic foundations of previous stride piano masters, Powell's long, running, right-hand lines combined with infrequent and irregular interjections by the left hand provided another layer of rhythmic complexity to the bebop combo while also elevating the piano to a more prominent frontline role within the ensemble.
Krall then lit into "We Just Couldn't Say Goodbye" with some romping stride piano and a brassy vocal before moving effortlessly to "There Ain't No Sweet Man That's Worth the Salt of My Tears," a novelty song that the singer transformed into a belting blues.
The turning point he identifies, and you can hear it on this double album, are three buoyant romps in the great stride piano tradition (two Fats Wallers, Ain't Misbehavin' and Honeysuckle Rose, and a hard-swinging Rodgers & Hart, You Took Advantage of Me).
Elsewhere on the CD, Hornsby tries out some stride piano on "What the Hell Happened" and "Heir Gordon." His wife was the inspiration for the title track and "Dreamland," a modern soother that features Elton John and gospel singer Lloyd Jones on vocals that was intended as a lullaby for one of his twin sons.
(So were Harlem's stride piano stylings, which derived from ragtime's similar beat.) With its increased emphasis on a different format for dancing--the ragtime period's cakewalk doesn't have much in common with the foxtrot, rumba or lindy--the Swing Era smoothed those somewhat herky-jerky two-beat measures out to a more easily flowing four-beat bar.
His piano improvisation on this selection moved seamlessly from stride piano to 1930s swing to bop and beyond.

His show features a range of piano styles but he is rooted in the "stride piano" sound, named after the distinctive walking left-hand technique.
It's exhilarating to here Chopin suddenly twist and turn into stride piano jazz, and Valdes pays an appropriate debt to Art Tatum.
Militello contributed another incendiary saxophone solo in the style of boppers Charlie Parker and Cannonball Adderley before giving way to Brubeck, who countered with a piano improvisation that began with some sketchy chords and evolved into a section of stride piano and several choruses of big block chords underpinned by Smith's booming walking bass line and Cox's drum accents.
