Research on Key Technology of Enterprise Private Cloud Anti-Leakage

With the rapid development of Internet and cloud computing technology, more and more enterprises use private cloud for collaborative work. Important data protection has become the focus of enterprise security protection. Based on the need of data anti-leakage, content monitoring and filtering security techniques were studied. And the private cloud anti-leakage prototype system was realized, which provided real-time monitoring for internal staff's intentional or unintentional leakages and the leakages caused by the implantation of malicious code from external attackers. When sending files containing pre-set sensitive words, the system will remind the user and inform the administrator. The received document is embedded with executable script code or the document itself is binary code, and dynamic and static combination detection will be performed. If the document includes malicious code, then warning information will timely feedback to the administrator to strengthen the enterprise information security management.
