About 52% of IT security professionals are not sure their IT staff would be able to detect intruders on their network, according to a new survey.

Lieberman Software’s latest survey also revealed that 63% of respondents expect to be attacked by a state-sponsored hacker in the following six months, while 90% have already implemented methods to protect themselves.

However, 36% of those surveyed believed their security products and processes are not sustainable with new and emerging threats.

Another 89% had implemented endpoint testing to defend against advanced persistent threats (APT), while 81% of them carried out penetration testing.

Lieberman Software President and CEO Philip Lieberman said:"As our survey found, almost 90% of the senior IT security professionals we spoke to at Black Hat had invested in penetration testing services or education of users, and it is good to see such a high number making preparations for the worst eventuality," Lieberman said.

About 74% of respondents were not confident about their network being hacked by a foreign state-sponsored attack or an APT.

Of the 200 surveyed, 70% of them used security measures, such as user training, security appliances, end point testing and pen testing, while 1.1% of them used none.

Another 58% of survey respondents said the US is losing the fight against state-sponsored attacks.
