Create a similar DLP awareness program by rewarding

your users for not violating DLP policies.

– Explain to your users about DLP policy breaches (as

much as possible).

– Create a “Culture of Trust”.

– Keep track of the assets you provide your users and

collect them when they leave.

– Come to an agreement about using personal devices for

work, i.e. Android, iPhone, iPad, HP Slate

– Don’t assume that your employees are already aware of

IT security best practices.

“Company data continues to be put at risk not by

ingenious code breaking on the part of hackers but by

careless mistakes made by employees. The global study by

Insight Express and funded by Cisco, concludes that

education of workers to the impact of their behavior should

be the first line of defense. “

“The findings of inadequate training come at a particularly

dangerous time. The penalties and marketplace damage

from data losses are bigger than ever. In addition, data loss

is increasingly occurring not from hackers or deliberate

theft but due to mishandling, human error, carelessness,

technical failure, or other inadvertent cause. “

Intellectual Property Loss

• According to The Associated Press, 33-year-old

Biswamohan Pani downloaded the confidential documents

- worth up to $1 Billion dollars (insert Dr. Evil grin here) -

back in June after resigning from rival microprocessor

manufacturer Intel. However, before leaving the company,

he used his remaining paid vacation days, thus sat at home

with full access to Intel’s network and earning a paycheck

while gathering trade secrets. At the same time, Pani also

began working for AMD. Naturally, the situation sounds

rather suspicious on AMD’s part.
