Advanced Persistent Threats and Human Errors

In these days many people are asking me what they can do to stop an Advanced Persistent Threat. Although security firms are running fast to develop new technologies to thwart these attack vectors (sophisticated SIEMs and a new breed of network security devices, the so called Next Generation IPSs), unfortunately I am afraid the answer is not so easy. I might spend thousands of words to figure out the answer, but I would not be able to give a better representation than this cartoon I found a couple of days ago in the Imperva Blog.

Advanced Persistent Threats and Security Information Management

Advanced Persistent Threats are probably the most remarkable events for Information Security in 2011 since they are redefining the infosec landscape from both technology and market perspective.

I consider the recent shopping in the SIEM arena made by IBM and McAfee a sign of the times and a demonstration of this trend. This is not a coincidence: as a matter of fact the only way to stop an APT before it reaches its goal (the Organization data), is an accurate analysis and correlation of data collected by security devices. An APT attack deploys different stages with different tactics, different techniques and different timeframes, which moreover affect different portion of the infrastructure. As a consequence an holistic view and an holistic information management are needed in order to correlate pieces of information spread in different pieces of the networks and collected by different, somewhat heterogeneous and apparently unrelated, security devices.

Information, The Next Battlefield

Today the Information Security Arena has been shaken by two separate, although similar, events: IBM and McAfee, two giants in this troubled market, have separately decided to make a decisive move into the Security Information And Event Management (SIEM) market by acquiring two privately held leading companies in this sector.

As a matter of fact, nearly in contemporary, today IBM has officially announced to acquire Q1 Labs while McAfee was officially declaring its intent to acquire privately owned company NitroSecurity.

Violati i Server RSA

Stamattina mi sono svegliato con una di quelle notizie la cui eco rimbomberà per un bel pezzo nell’arena Infosec. Il blog di Sophos riporta difatti che la nota azienda di sicurezza RSA, specializzata in sistemi di autenticazione forte (in pratica da lei inventati) è stata vittima di un attacco informatico che ha portato alla sottrazione di alcune importanti informazioni.

La notizia è stata comunicata da RSA stessa mediante uno stringato comunicato sul proprio sito. Sebbene l’Azienda sia riuscita a rilevare l’attacco e abbia da subito rafforzato le misure di sicurezza, purtroppo non ha potuto impedire la sottrazione di preziose informazioni dai propri server tra cui alcune relative al sistema di autenticazione forte OTP a due fattori, RSA Secure-ID, che da anni costituisce la soluzione ammiraglia della Casa (che di fatto ha inventato l’omonimo algoritmo di crittografia asimmetrica). Chi di noi non ha mai utilizzato almeno una volta il piccolo quadrante con i numerini magici che cambiano ogni 10 secondi?
