A company recently experienced several security breaches that resulted in confidential data being infiltrated
form the network. The forensic investigation revealed that the data breaches were caused by an insider
accessing files that resided in shared folders who then encrypted the data and sent it to contacts via third party
email. Management is concerned that other employees may also be sending confidential files outside of the
company to the same organization. Management has requested that the IT department implement a solution
that will allow them to:
Track access and sue of files marked confidential, provide documentation that can be sued for investigations,
prevent employees from sending confidential data via secure third party email, identify other employees that
may be involved in these activities.
Which of the following would be the best choice to implement to meet the above requirements?
Web content filtering capable of inspe4cting and logging SSL traffic used by third party webmail providers
Full disk encryption on all computers with centralized event logging and monitoring enabled
Host based firewalls with real time monitoring and logging enabled
Agent-based DLP software with correlations and logging enabled
