DESCRIPTION

Malware is getting more and more sophisticated and capable to circumvent traditional security technologies, redefining the information security landscape. Firewalls, Next Generation Firewalls and Intrusion Prevention Systems are converging to a new breed of security devices capable of moving the security enforcement paradigm to context, taking over the old model based on IP Address, Protocol and Access Control to a new model focused on user, application and anomaly.

Why Next Generation Technologies Are Needed Malware is getting more and more sophisticated and capable to circumvent traditional security technologiespaulsparrows.wordpress.com 3. APTs Are Changing The Rules Of The GameAPTs threaten Organizations on different levels (from users to application) andheterogeneous time scales, redefining the information security landscape. Firewalls, NextGeneration Firewalls and Intrusion Prevention Systems are converging to a new breedof security devices capable of moving the security enforcement paradigm to context, takingover the old model based on IP Address, Protocol and Access Control to a new modelfocused on user, application and anomaly.paulsparrows.wordpress.com 4. The Next Level: From Content to ContextContext-aware security is the use of supplemental information to improve securitydecisions at the time the decision is made. Supplemental Information include: GeoLocation, Reputation, and the interaction of the user with the environment (applications,directory, etc.). This class of devices is called Next Generation IPS:http://blogs.gartner.com/neil_macdonald/2011/10/13/next-gen-context-aware-intrusion-prevention/ paulsparrows.wordpress.com 5.

Web Application Firewalls The growing number of vulnerabilities targeting Web Applications and cyber attacks carried on against banks together with the need to be compliant with strict requirements and regulations are pushing the adoption of Web Application Firewalls. Although Technology tends to consolidate traditional security solutions, WAFs are destined to remain standalone dedicated devices in front of key web assets to protect. These devices are required by PCI-DSS and most of all by the growing attention by Cybercrookers for exploiting vulnerabilities in banking web applications. Only this year, famous victims included CitiGroup and Samsung Card. In particular attackers were able to subtract $2.7 million to Citigroup. http://spectrum.ieee.org/riskfactor/telecom/security/citigroup-admits-being-hacked-in- may-coy-about-extent-of-impact http://www.databreaches.net/?p=20522paulsparrows.wordpress.com 7.

So Which Is The Most Revolutionary Technology?Avoid to invest in new technologies without first patching the user!APT Holds only for 1%, (human) vulnerabilities for theremaining 99%paulsparrows.wordpress.com 9.
