Just a 7 letter word that defines something that we never want to come in contact with - HACKERS.

 

Anyone can download and exploit from the internet and use it to break into an under-protected network. Although, there are numerous times that the likely culprit in any malicious data breach is a disgruntled employee. An employee may get upset and before thinking before they act, the project they were working on is deleted or the customer mailing list has been copied and erased.

 

Any server or machine that is kept up to date with operating system updates and anti-virus definitions are protected against most vulnerabilities and exploits. A robust network security system will prevent an innocent user from poking around and downloading software that they shouldn't be, and preventing them from accessing files that they shouldn't have access to. 

 

The best way to keep anyone, an employee, or an ex-employee from abusing their credentials is with remote instant account freezing. Before they even find out that they have something to be upset about, the employee's access can be revoked and their communications will be forwarded. Although, this doesn't help much in a business environment where employees insist on sharing office passwords, and keeping machines unlocked. When a network is chronically left open in this way, the best a business owner can hope for is the kindest of their fellow employee.
