Gli ultimi ritrovati in termini di attacchi alle aziende e furti di dati, come combatterli Roma 18 Giugno 2014 Maurizio Martinozzi Gli ultimi ritrovati in termini di attacchi alle aziende e furti di dati Degli Advanced Persistent Threats (APT) non solo se ne parla ma ad oggi se ne cominciano a contare i danni: è possibile contrastarli ma la difesa deve essere personalizzata e “tagliata su misura” dell’infrastruttura dell’azienda. Una ricerca del Ponemon Institute ha rilevato che il 67% delle aziende ammette che le proprie soluzioni sicurezza adottate non sono sufficienti a bloccare un attacco mirato. Ma il dato è tragico se consideriamo che il 55% delle aziende non viene nemmeno a conoscenza delle intrusioni subite e, una percentuale bassissima, è in grado di valutare la portata dell’attacco e, ancora più importante, chi lo ha sferrato. Per contrastare gli attacchi mirati è necessario adottare tecnologie si sicurezza evolute, quelle tradizionali non garantiscono più un adeguato livello di protezione. Di fatto le nuove tecnologie devono essere in grado di gestire la tipologia di attacco, rilevando e analizzando le minacce costanti evolute, ma anche di adattando rapidamente la protezione e reagendo in maniera proattiva ad attacchi specifici. La tecnologia deve essere in grado di integrare correttamente software, informazioni globali sulle minacce, strumenti e servizi specializzati per offrire nozioni personalizzate sulla minaccia specifica e sui criminali coinvolti. I recenti progressi nella gestione di comando e controllo (C&C) contribuiscono a bloccare i comportamenti sospetti prima ancora che riescano a compromettere l’obiettivo individuato. Ma non allarmiamoci: oggi sono disponibili specifiche soluzioni preventive e noi ve le racconteremo: vi spiegheremo perchè le soluzioni di sicurezza tradizionali non riescono a combattere queste nuove tipologie di minacce e di attacchi, vi spiegheremo le caratteristiche di queste recenti attività illecite dei cybercriminali e, soprattutto, vi mostreremo le più recenti e efficienti soluzioni ad oggi disponibili sul mercato per combattere questi nuovi crimini informatici.

Public Cloud Desktop Virtualization Private Cloud Server Virtualization The Targeted Attack Process Stage 0 Stage 2 Stage 1 Preparation for attack Initial penetration Establishment of attack platform As a preparation stage before they conduct attacks, the Various methods are used in the initial penetration stage. Once the attackers succeed to get into the system, they quickly attackers investigate information of target organization. Suspicious (targeted) email is one such method. For that, they attack organizations around target to collect platform information for initial intrusion like Emails exchanges between that organization and the target. Using this information, they conduct attacks which increase the success rate of the initial penetration. Copyright 2012 Trend Micro Inc. These methods are used to deploy viruses deep within the organization. In this stage, the attack can achieve the goal only when establish a backdoor for communication with a server they prepare. Unlike the traditional backdoors , this backdoor is the one that uses HTTP and other communication protocols that are used in the business in the target one employee open that Email. organization. Thus it In the initial penetration stage, there is no need for virus to infect many systems. It is thought that the attack methods used at this stage are expected to be detected and cleaned. That mean they are disposable. Using this backdoor, they will add functions needed for next system investigation stage, and an attack platform will be established. 20 cannot be blocked by a firewall. Stage 3 Stage 4 System investigation Attack on the ultimate target Using the attack plat-form established in the prior stage, They steal information the attackers search In some cases, using information stolen, they repeat attacks. for internal system information. via the backdoor. used to communicate APT is the attack which the attackers keep attack platform which established in the target with the attackers and organizations to repeat the search will be continued while confirming system information. penetrations and data thefts. At this time, a back door is This attack is the one tend to be repeated several times. Source: IPA design/ maintenance guide to aim for the solution against “new type of attack”.
