Symantec's security operations centre analyses more than one billion logs per day, as part of a global network monitoring attacks on computer networks for 650 customers.

And the centre faces a growing threat, with a 140 per cent increase in the amount of malware being deployed online over the past six months.

Today the 24/7 centre deals with more than 3,200 security incidents and sees 10 security incidents escalated every day.

Alan Osborne, senior manager of global technical operations for Symantec managed security services, said: "We are seeing more escalated security events now. There are a reasonable number of severe security incidents.

"If it's a critical security event then we will ring the client whatever time it is day or night, we will get them out of bed if necessary."
