A survey of 583 businesses of all sizes and industries shows that 90 percent of them have been hacked in the last year. The survey also shows that companies need to prepare for containing the effects of an attack, rather than just preventing them. No matter how good your security is you always need a Plan B in case an attack gets through.
With the increasing number of high profile hacks in the news lately it’s only a matter of time before every company has its security breached, even if it’s in a relatively minor way. Following industry best practices to harden your IT infrastructure, protect your sensitive data, and contain future attacks isn’t as hard as many people assume it is. As Benjamin Franklin said, “An ounce of prevention is worth a pound of cure.”
