One of the biggest threats to corporate data and systems traditionally comes from insiders, as they have access to data and systems and actually pose more of a potential threat to do malicious or accidental damage, more so than an outsider. If your company has an enterprise firewall, you can trust that no one will be able to access and take privileged data from computer networks.
An example of insiders causing problems with sensitive information would be in San Francisco in 2008. A disgruntled city administrator locked access to an important network by resetting administrative passwords to its switches and routers, then refusing to divulge the passwords to officials. This of course is highly illegal, but poses a realistic threat to the world of cyber security.
In 2011, there were nearly 43,000 incidents in America involving data loss or theft, computer intrusions and privacy breaches. However, in the same year, a study showed that both the cost of a security breach and the cost per lost or stolen record have declined. At the same time, it takes over 11 months for a company that experiences a cyber security breach to rebuild their reputation.
The best intrusion detection systems are often in place among companies that handle sensitive data. Network security platforms and network firewalls create a powerful security system in which outsiders are hard pressed to find a way into the system and insiders have to follow specific steps in a security protocol. Next gen network security involves things like enterprise firewalls, and can provide consumers the peace of mind to know things like credit card information and personal data is safe and hidden from potential attackers.
