Ofufuza ochokera ku Red Balloon anena za zovuta ziwiri zomwe zapezeka mu ma routers a Cisco 1001-X. Zowopsa pazida zapaintaneti za Cisco si nkhani, koma zenizeni pamoyo. Cisco ndi m'modzi mwa otsogola opanga ma routers ndi zida zina zapaintaneti, kotero pali chidwi chochulukirapo pakudalirika kwazinthu zake kuchokera kwa akatswiri oteteza deta komanso momwe akuwukira.
Tikuyang'ana m'tsogolo, tikuwona kuti akatswiri a Red Balloon adadziwitsa Cisco za zovuta zatsopano miyezi ingapo yapitayo, kotero vutoli lathetsedwa mwanjira ina, kapena Cisco amadziwa momwe angalithetsere. Chimodzi mwazovuta ziwirizi chitha kutsekedwa pang'onopang'ono pokonzanso firmware, ndipo kampaniyo idatulutsa firmware yotere dzulo pagulu la anthu, lipoti lofalitsidwa pa intaneti. . Tikukamba za cholakwika chomwe chimapezeka mu makina opangira a Cisco IOS omwe amapatsa wowukira mwayi wopeza ma routers a mndandanda womwe watchulidwa.
Chiwopsezo chachiwiri ndichinthu chapadera komanso chowopsa kwambiri, ofufuzawo akutero. Imakhudza maziko achitetezo cha mazana mamiliyoni a zida zama network zamakampani, kuyambira ma routers kupita ku switch to firewall. Akatswiri a Red Balloon adatha kudutsa chitetezo cha zida za Cisco monga Trust Anchor. "Trust Anchor," monga momwe mawuwa angatanthauzire, ndikukulitsa ma module otsimikizira zida zamakampani (omwe kale anali ACT). Module ya ACT idayambitsidwa kuti itetezedwe kuzinthu zabodza ndipo pambuyo pake idasinthidwa kukhala gawo loyang'anira kukhulupirika kwa gawo la pulogalamu yamagetsi a Cisco network. Masiku ano, Trust Anchor ilipo pazida zonse zogwira ntchito zamakampani. Sizovuta kulingalira zomwe kunyengerera kwa Trust Anchor kungaphatikizepo. Maukonde pa zida za Cisco ndiye sadzadalirikanso.
Ofufuza apeza njira yonyenga Trust Anchor. Zida zomwe zidabedwa zidapitilirabe kudziwitsa makasitomala za kusasokoneza, pomwe akatswiri amachita chilichonse chomwe akufuna. Izi, mwa njira, zimatipangitsa kulingalira za tsogolo la zochitika zofanana ndi ARM (TrustZone), Intel (SGX) ndi njira zina zofananira za hardware zotetezera nsanja zamakompyuta. Zikuwoneka kuti iyi ndiye njira yothetsera kutseka mabowo muzomangamanga zama processor. Chip kapena gawo lodalirika la chipset lingapangitse makompyuta kukhala otetezeka kwambiri pakubera. M'zochita, dzenje kapena mwayi wodutsa chitetezocho unapezedwa ngakhale mu njira yothetsera vuto lomwe kulowa kuli kochepa kwambiri ndipo kawirikawiri kumatheka kokha kumalo opangira eni ake.
Mkhalidwe womalizawu udzakhala wofunikira pakutseka mabowo okhudzana ndi kusagwirizana kwa ma module a Trust Anchor. Ngakhale Cisco idalonjeza kumasula zigamba kuti akonze chiwopsezo cha Trust Anchor pazida zake zonse, kutsitsa zosintha sikungathetse vutoli. Cisco akuti izi zidzafunika "kukonzanso kwanuko," kutanthauza kuti sizingatheke kusintha zida zakutali. Inde, masiku otanganidwa akuyembekezera ogwira ntchito pamanetiweki pogwiritsa ntchito zida za Cisco. Ndipo chilimwe choyandikira sichikugwirizana ndi izi.
