APT Attackers Love Correlation Environments You remember that "False Sense of Security," the feeling that you are secure, but in fact you're not...? Attackers know that an attack is a process, it is not an event. And they use this - and they use time - to their advantage. They use time scales that static rule-based correlation simply cannot cope with. If you want to correlate disparate events, you need to keep state information on these events, and of course the longer you need to keep the state, the more expensive it becomes, expensive in RAM, CPU, storage etc etc., to the point where it is not affordable anymore.

First-party fraud involves fraudsters who apply for credit cards, loans, overdrafts and unsecured banking credit lines with no intention of paying them back. It is a serious problem for banking institutions.

60% of EMEA still NOT using Cloud Services

ISACA, the Information Systems Audit and Control Association just surveyed 1 529 of its members across 50 countries in EMEA. It turns out that UK businesses are leading Europe on Cloud Adoption 40% to 33%. But a whopping 35% of respondents do not plan to use Cloud for any IT services (actually 35.6% in Europe and 31.8% in the UK). This is a huge impediment to the growth of ItaaS – IT as a Service, such as SaaS, IaaS and PaaS respectively Software as a Service, Infrastructure as a Service and Platform as a Service. Let’s spin this another way: 60% of respondents are not using Clou... (more)
