To protect the federal civilian agencies against cyberthreats, the Department of Homeland Security (DHS) is preparing to deploy a more powerful version of its EINSTEIN intrusion-detection system that’s supposed to detect attacks and malware, especially associated with e-mail. But since this version of EINSTEIN is acknowledged by DHS to be able to read electronic content, it’s raising privacy concerns.

RSA, the security division of EMC, today announced Security Analytics, its tool for real-time analysis of large amounts of data from security and business information to determine if an organization is being attacked, especially by stealthy threats intent on stealing sensitive information.

An intrusion prevention system (IPS) includes all the features of an intrusion detection system but also has the ability to act upon malicious traffic. Since the IPS usually sits in line with network traffic it can shut down attacks, typically by blocking access from the attacker or blocking access to the target. In some cases, the IPS can talk to the firewall to block an attack.

Any enterprise looking to use cloud computing services will also be digging into what laws and regulations might hold in terms of security and privacy of data stored in the cloud. At the Cloud Security Alliance Congress in Orlando this week, discussion centered on two important regulatory frameworks now being put in place in Europe and the U.S.

Sourcefire Monday announced a new line of intrusion-prevention systems (IPS) that sets the foundation for the company's anticipated foray into the application-aware next-generation firewall market later this year.
