- Key Takeaways CIRC, SOC and SIEM are not always interchangeable terms. In some organizations their responsibilities are different and distinct. ***************************** To address APTs the security organization is faced with some growing and changing responsibilities. First and foremost, the need for a CIRC capability has become evident in many organizations. Responsibilities include the need to be able to identify anomalies, predict attacks and respond to incidents. This drives a need for additional intelligence. Traditional SOC responsibilities have included security help desk capabilities and the day-to-day administration of key technical controls including firewall, VPNs, access controls, AV, etc.. Another key capability includes SIEM. This is where many of the reports and alerts that are so important to the CIRC originate. Click: What does all this mean for you sitting here today? It means different stakeholders may have new and different needs but a unified strategy is needed to deal with new threats. Click: Traditional responsibilities across the board are undergoing review. This more than just updating technical responsibilities and controls. This requires updating our Business and Operations models to deal with new Enterprise dimensions.
- The first step in this attack was phishing, or more accurately “spear phishing,” meaning that the attack targets specific people .
- Zero-Day attack in this case was launched when one user opened the email . The zero day then installed a backdoor (variant of the POISON IVY remote access Trojan) which then immediately set about reconnaissance and cultivation. It’s important to note as well that the attacker was creating layers of resilience and was making maximum use of the window of exposure.
- The zero day then installs a backdoor which then immediately sets about reconnaissance and cultivation. During this time, the attacker can creating layers of resilience and was making maximum use of the window of exposure.
- The attacker encrypts sensitive files found on the critical server and transfers out via an FTP These attacks are focused and coherent: the timing is choreographed and the attacker moves rapidly and unerringly. They know what to get and the order to get items in. This type of attack can take months or perhaps years of preparation prior to staging the attack itself. It reflects an ability to move with exacting precision.
