Compania Google a prezentat<\/a><\/noindex> modific\u0103rile iminente din Chrome, menite s\u0103 enhance confiden\u021bialitatea. Prima parte a modific\u0103rilor se refer\u0103 la gestionarea cookie-urilor \u0219i la suportul atributului SameSite. \u00cencep\u00e2nd cu lansarea Chrome 76, a\u0219teptat\u0103 \u00een iulie, va fi activat<\/a><\/noindex> Steagul «same-site-by-default-cookies», care, \u00een absen\u021ba atributului SameSite \u00een antetul Set-Cookie, va seta \u00een mod implicit valoarea «SameSite=Lax», limit\u00e2nd trimiterea Cookie-urilor pentru inser\u021biile de pe site-uri externe (\u00eens\u0103 site-urile vor putea anula \u00een continuare aceast\u0103 restric\u021bie, set\u00e2nd \u00een mod explicit valoarea SameSite=None la instalarea Cookie-urilor).<\/p>\n

Atributul SameSite<\/a><\/noindex> permite definirea situa\u021biilor \u00een care este acceptat\u0103 transmiterea cookie-urilor atunci c\u00e2nd se prime\u0219te o cerere de pe un site extern. \u00cen prezent, browserul trimite cookie-uri la fiecare cerere c\u0103tre un site pentru care exist\u0103 cookie-uri instalate, chiar dac\u0103 este deschis ini\u021bial un alt site, iar accesul se face indirect prin \u00eenc\u0103rcarea unei imagini sau printr-un iframe. Re\u021belele de publicitate utilizeaz\u0103 aceast\u0103 caracteristic\u0103 pentru a urm\u0103ri mi\u0219c\u0103rile utilizatorului \u00eentre site-uri, iar
\natacatorii pentru a organiza attaques CSRF<\/a><\/noindex> (atunci c\u00e2nd se deschide un resurs\u0103 controlat\u0103 de atacator, de pe pagina acestuia se trimite \u00een mod ascuns o cerere c\u0103tre un alt site, pe care utilizatorul curent este autentificat, iar browserul utilizatorului seteaz\u0103 pentru aceast\u0103 cerere cookie-urile de sesiune). Pe de alt\u0103 parte, posibilitatea de a trimite cookie-uri c\u0103tre site-uri externe este folosit\u0103 pentru inserarea pe pagini a widget-urilor, de exemplu, pentru integrarea cu YouTube sau Facebook.<\/p>\n

Prin intermediul atributului SameSite, se poate controla comportamentul la instalarea Cookie-urilor \u0219i se poate permite trimiterea acestora doar \u00een r\u0103spuns la cereri ini\u021biate de pe site-ul de la care au fost ob\u021binute aceste Cookie-uri. SameSite poate lua trei valori: «Strict», «Lax» \u0219i «None». \u00cen modul ‘Strict’, Cookie-urile nu sunt trimise pentru niciun tip de cereri \u00eentre site-uri, inclusiv toate linkurile externe. \u00cen modul ‘Lax’, se aplic\u0103 restric\u021bii mai bl\u00e2nde iar trimiterea Cookie-urilor este blocat\u0103 doar pentru subcereri \u00eentre site-uri, cum ar fi o cerere de imagine sau \u00eenc\u0103rcarea de con\u021binut prin iframe. Diferen\u021ba dintre «Strict» \u0219i «Lax» se reduce la blocarea Cookie-urilor la accesarea hyperlinkurilor.<\/p>\n

Printre alte modific\u0103ri anticipate, se preconizeaz\u0103 aplicarea unei restric\u021bii stricte care interzice procesarea Cookie-urilor externe pentru cereri f\u0103r\u0103 HTTPS (cu atributul SameSite=None, Cookie-urile pot fi setate numai \u00een modul Secure). \u00cen plus, se planific\u0103 m\u0103suri pentru a proteja \u00eempotriva utiliz\u0103rii identific\u0103rii ascunse («browser fingerprinting»), inclusiv metode de generare a identificatorilor pe baza datelor indirecte, cum ar fi rezolu\u021bia ecranului<\/a><\/noindex>, lista tipurilor MIME acceptate, parametrii specifici din antet (HTTP\/2<\/a><\/noindex> \u0219i HTTPS<\/a><\/noindex>), analiza plugin-urilor \u0219i fonturilor instalate , disponibilitatea anumitor API-uri Web, specifice pl\u0103cilor video<\/a><\/noindex>caracteristici grafica realizat\u0103 prin WebGL \u0219i<\/a><\/noindex> redarea prin WebGL \u0219i Canvas, cu CSS,<\/a><\/noindex> cu CSS, analiza caracteristicilor de lucru cu mouse-ul<\/a><\/noindex> \u0219i tastatura<\/a><\/noindex>.<\/p>\n

\u00cen plus, \u00een Chrome va fi ad\u0103ugat\u0103<\/a><\/noindex> protec\u021bia \u00eempotriva abuzurilor legate de dificult\u0103\u021bile de revenire pe pagina de origine dup\u0103 redirec\u021bionarea c\u0103tre un alt site. Se vorbe\u0219te despre practica de a supraaglomera istoricul de navigare cu o serie de redirec\u021bion\u0103ri automate sau ad\u0103ugarea artificial\u0103 de \u00eenregistr\u0103ri fictive \u00een istoricul de vizionare (prin pushState), rezult\u00e2nd c\u0103 utilizatorul nu poate folosi butonul «Back» pentru a se \u00eentoarce pe pagina de origine dup\u0103 o redirec\u021bionare accidental\u0103 sau o redirec\u021bionare for\u021bat\u0103 c\u0103tre un site de escroci sau r\u0103u-inten\u021bionat. Pentru a se proteja \u00eempotriva acestor manipul\u0103ri, Chrome va s\u0103ri peste \u00eenregistr\u0103rile legate de redirec\u021bion\u0103rile automate \u0219i manipul\u0103rile istoricului de vizionare, l\u0103s\u00e2nd doar paginile deschise prin ac\u021biuni explicite ale utilizatorului.<\/p>\n
