FireMon’s Annual State Of The Firewall Report Finds Chronic Deficiencies In Basic Firewall Hygiene

Chaos and confusion reign with existing firewall Infrastructure; hybrid cloud and next-gen architectures promise to add even more complexity and risk

 FireMon, a global leader in network security policy management, today released its 2018 State of the Firewall report. The fourth annual study polled 334 C-suite executives, IT practitioners and security professionals at global companies of all sizes to understand the state of firewall management, along with the impact of emerging technologies. The survey found that many organizations are still struggling to master basic firewall hygiene, promising increased complexity and risk associated with network security policy management for those planning to adopt hybrid cloud models and next-gen architectures.

 Long Live Firewalls!

The majority of respondents believe the firewall is still an important part of their overall security architecture, with 94% saying firewalls are as critical as always or more critical than ever. The same percentage of survey takers believe the firewall will be just as critical or more critical to their overall security architecture over the next five years. And companies are backing up their beliefs with budget dollars: Nearly one fourth (24%) allocate more than 25% of their total network security budget to firewall technology (hardware, software, maintenance), while 39% devote between 10 and 24%.

Despite the prominent stature of firewalls within security infrastructures, companies are still struggling with basic firewall management, with rule complexity (30%), policy compliance and audit readiness (17%), and firewall rule optimization (14%) emerging as major pain points. The report identifies two contributing factors to firewall management challenges:

• The number of firewalls security and IT teams are trying to manage: More than one-fourth (26%) of companies have 100 or more firewalls on their network, while 33% have between 10 and 99.
• The number of change requests processed each week: 16% of companies process more than 100 change requests each week, while 40% deal with between 10 and 99 requests.

“Many companies are still trying to manage firewall rules manually, but in this era of next-gen architectures and sophisticated malware, this is no longer an effective way to enforce access policies and mitigate risk,” said FireMon CEO Satin Mirchandani. “With more than half of survey respondents stating that three or more teams are involved in change management, the high number of change requests alone can drain valuable time, resources and budget from any security program. Factor in new technology adoption, and the stage is set for further policy management problems.”

Cloud Computing and Next-Gen Security Architectures Blur the Firewall’s Role

Though survey respondents believe firewalls will be a fundamental component of security infrastructures over the next five years, the role of firewalls in next-gen architectures is unclear to many business, IT and security professionals.

 53% of companies have either partially or fully adopted a public and/or hybrid cloud model, yet only 35% believe firewalls provide “high value” for the cloud services they manage.

• Respondents state they are also considering implementing the following next-gen security architectures: virtualization (54%), software-defined networks (41%), microsegmentation (29%), containerization (28%) and zero trust (23%).
  • 27% of survey takers believe enterprise firewalls will become obsolete with these next-gen architectures, while 26% aren’t sure. The remaining 47% do not think firewalls will become obsolete in the wake of these new technologies.

“Firewalls will not become obsolete with next-gen architectures, but the old way of writing firewall rules will,” continued Mirchandani. “The erosion of a defined corporate perimeter has simultaneously increased the number of assets organizations are trying to protect as well as the number of firewall rules. The only way to enforce consistent access policies across the enterprise is to implement automated, intent-based security. By decoupling security intent from implementation, organizations can ensure continuous compliance with enterprise security intent, even when the network evolves.”
