Critical PennNet Hosts
A critical host is a Server which, if compromised, could significantly harm the University. Schools and centers may optionally designate any hosts as critical if its compromise could significantly harm the local unit. Examples of significant harm could include legal liability, reputational damage, interruption of critical business functions, and disclosure of confidential information.
