Despite the security policies, standards, awareness strategies and tools currently in place, employees are still involving in risky behaviors that put business at risk. The growth and proliferation of Social Networks Services (SNS), among other threats, have made possible new leakage avenues for sensitive data, and malware spread. To address these security issues, network and security managers often turn to network policy management services such as firewall, Intrusion Prevention System (IPS), antivirus, and Data Loss Prevention systems (DLP). However, without a consistent strategy the desired control may be circumvented. As its outcome, this paper addresses a security framework to protect corporate information against the threats related to SNS.
