The Tangled Web: A Guide to Securing Modern Web Applications

"Thorough and complete insurance from one of many most efficient specialists in browser safeguard. "
--Tavis Ormandy, Google Inc.

Modern net functions are equipped on a tangle of applied sciences which were built over the years after which haphazardly pieced jointly. every bit of the net program stack, from HTTP requests to browser-side scripts, comes with vital but refined defense results. to maintain clients secure, it really is crucial for builders to hopefully navigate this landscape.

In The Tangled internet, Michal Zalewski, one of many world's best browser defense specialists, bargains a compelling narrative that explains precisely how browsers paintings and why they're essentially insecure. instead of dispense simplistic recommendation on vulnerabilities, Zalewski examines the total browser protection version, revealing susceptible issues and offering the most important info for shoring up internet software safeguard. You'll find out how to:
* practice universal yet unusually advanced projects comparable to URL parsing and HTML sanitization
* Use glossy safety features like Strict shipping safeguard, content material safety coverage, and Cross-Origin source Sharing
* Leverage many variations of the same-origin coverage to soundly compartmentalize advanced net purposes and defend person credentials in case of XSS insects
* construct mashups and embed contraptions with no getting stung through the tough body navigation coverage
* Embed or host user-supplied content material with out working into the seize of content material sniffing
for fast reference, "Security Engineering Cheat Sheets" on the finish of every bankruptcy supply prepared recommendations to difficulties you're probably to come across. With assurance extending so far as deliberate HTML5 beneficial properties, The Tangled internet may also help you create safe internet functions that stand the try of time.

The Information Security Dictionary Defining The Terms That Define Security For E-Business, Internet, Information And Wireless Technology

Whatever for everybody If this publication is to be successful and aid readers, its cardinal advantage needs to be to supply an easy reference textual content. it's going to be a necessary addition to a data safety library. As such it may additionally serve the aim of being a brief refresher for phrases the reader has no longer noticeable because the days while one attended a computing technology software, details defense direction or workshop.

Einführung in die Kryptographie (Springer-Lehrbuch)

"Bist du nicht willig, so brauch` ich Gewalt" -- ein Grundsatz, der mit moderner PC-Leistungsfähigkeit auch für einige Verschlüsselungsmethoden gilt. Im Zuge der immer weiter gehenden Vernetzung von Unternehmen, Haushalten und Privatpersonen wird ein gesicherter Datentransfer immer wichtiger. Auch wenn einige Institutionen gern suggerieren, guy befinde sich in einem hochgradig mafia-nahem Zustand, wünsche guy eine sichere Verschlüsselung für deepest email, zeigen politische Streitereien um weltweite Abkommen die Brisanz und Wichtigkeit starker Verschlüsselungstechniken.

In the C function for squaring the initialization in step 1 is likewise, in analogy to multiplication, replaced by the calculation and storing of the first partial product a0 (an−1 an−2 . . a1 )B . 42 The Fundamental Operations Function: squaring Syntax: int sqr_l (CLINT f_l, CLINT pp_l); Input: f_l (factor) Output: pp_l (square) Return: E_CLINT_OK if all is ok E_CLINT_OFL if overflow int sqr_l (CLINT f_l, CLINT pp_l) { register clint *pptr_l, *bptr_l; CLINT a_l; CLINTD p_l; clint *aptr_l, *csptr_l, *msdptra_l, *msdptrb_l, *msdptrc_l; USHORT av; ULONG carry; int OFL = E_CLINT_OK; cpy_l (a_l, f_l); if (EQZ_L (a_l)) { SETZERO_L (pp_l); return E_CLINT_OK; } msdptrb_l = MSDPTR_L (a_l); msdptra_l = msdptrb_l - 1; The initialization of the result vector addressed by pptr_l is carried out by means of the partial product a0 (an−1 an−2 .

A multiplication function that followed exactly the schema outlined above would first calculate all partial products, store these values, and then sum them up, each provided with the appropriate scaling factor. This school method is quite suitable for calculating with pencil and paper, but for the possibilities of a computer program it is somewhat cumbersome. A more efficient alternative consists in adding the inner products ai bj at once to the accumulated values in the result digit pi+j , to which are added the carries c from previous steps.

Set j ← i + 1 and c ← 0. 4. Set t ← pi+j + ai aj + c, pi+j ← t mod B , and c ← ⌊t/B⌋. 5. Set j ← j + 1; if j ≤ n − 1, go to step 4. 6. Set pi+n ← c. 7. Set i ← i + 1; if i ≤ n − 2, go to step 3. 8. Multiplication of inner products by 2: Set i ← 1 and c ← 0. 9. Set t ← 2pi + c, pi ← t mod B , and c ← ⌊t/B⌋. 10. Set i ← i + 1; if i ≤ 2n − 2, go to step 9. 11. Set p2n−1 ← c. 12. Addition of the inner squares: Set i ← 0 and c ← 0. 13. Set t ← p2i + a2i + c, p2i ← t mod B , and c ← ⌊t/B⌋. 14. Set t ← p2i+1 + c, p2i+1 ← t mod B , and c ← ⌊t/B⌋.
