3 perimeter security challenges, and how organizations can fix them

perimeter securityIT administrators have plenty of perimeter security tools at their disposal, from firewalls to spam filters to intrusion detection solutions. But despite all the preventative measures, most organizations still have gaps in their security controls or processes, which could lead to cracks in their system. A coordinated attack from an outside threat could penetrate these seemingly thick walls of perimeter security due to poor security management and overlooked system vulnerabilities.

Securing a network’s perimeter, defined as the demarcation point for exchanges among data, assets, employees, and partners, is a struggle for many organizations because of its complexity. IT departments can be easily overwhelmed by operating a complete perimeter security system because individual solutions are often stitched together, and therefore require multiple management controls, protocols, and licenses.

In response to individual threats, the piecemeal approach of perimeter security is often deployed over many years.
