Corporations increasingly realize the need to align their security practices with their business priorities. Crypto-segmentation is a new approach to protecting applications and the data they access from hackers who have become adept at penetrating corporate systems.
Cybercriminals are well rehearsed in finding ways inside of corporate networks. It’s not new territory, nor is it a hard task for them to achieve. After easily bypassing firewalls, hackers are able to move laterally from application-to-applications until they find the most sensitive and valuable data. Overcoming this security challenge is one of the biggest tasks facing information security managers today.
Micro-segmentation is a technology that technology advisory firm Gartner has identified as one of the must-haves for enterprise security in 2016. Crypto-segmentation is a form of this that works by cryptographically isolating workloads and encrypting network traffic end-to-end, therefore preventing lateral hacker movement and keeping data secure.
Cypto-segmentation protects applications and data by isolating individual applications and granting access only to authorized users based on business rules and authentication policies. This makes lateral movement across applications impossible, thus isolating hackers from doing extensive damage throughout a corporate environment.
Software-defined, cryptographic segmentation techniques allow:
Cryptographic segmentation certainly requires a new way of thinking. While organizations have worked hard on creating robust security strategies, with security experts across the globe now recommending a containment policy based on clearly defined infrastructure segments, it is time to make the change.
