Firewall Policy Challenges

As a firewall admin, the challenges associated with firewall rules, firewall compliances, firewall policies and firewall changes secure your business networks and systems are not centered only around the firewall technology itself, but also on how the firewall configuration is integrated with your business security policies.

With the growing number of applications and devices, network ecosystems have become so complicated that a simple oversight on a precarious firewall may render the entire network offline and endanger the security of the business to various forms of cyber-attacks.

Poorly implemented firewall policy management solutions can result in substantial business risks and often by the time it is revealed, the damage has already been done; take for example:

  • Redundant firewall rules that result in illegal network access and cyber-attacks
  • Differences in firewall compliances that are part of government and industry regulations
  • Inappropriate firewall rule modifications that interrupt business applications

When it comes to firewall change management, simple oversights and blunders can cause problems that will expose the network to security risks.

Additionally, the complexity of today’s networks, devices, applications and the tasks performed within the management solution, require a strong firewall policy management solution in place.

FAQ

Firewall administrators must know how to properly and effectively manage firewalls to make sure that the IT infrastructure and the business are protected against external and internal unauthorized and potentially harmful network risks.

How do you make firewall policies effective?

Using a firewall is about creating and establishing intelligent and effective firewall policy decisions. Firewalls are more than capable of implementing policies by translating firewall rules established by the firewall administrator. Then again, as a firewall admin, you must understand the types of firewall rules that will make sense on your current infrastructure. Ordinarily the time investment needed with firewall optimization relies heavily on the initial setup, leaving firewall policy management fairly simple. Although it may take some time, ideas and testing to come up with a firewall security policy that best serves your business requirements, doing so will provide you better control over the security of your network.

How long does it take to implement security policy changes?

Depending on the firewall policy management tools you use, you can actually process security policy changes within minutes or hours. The good thing about using highly customizable and smart workflows is that it simplifies and automates the whole process of modifying your firewall policies from the first stage of planning to designing a practical risk analysis to implementation, validation and auditing.

How do you create a change management workflow?

Every change task category or configuration change category needs to have a workflow linked to it. Creating a workflow is required prior to creating a change category or change task category. Technically, you can generate a new workflow from scratch or you can opt to just copy an already existing workflow and create the necessary modifications.

How to manage firewall rules?

The firewall policy management interface enables network administrators to either enable or disable firewall policies with the purpose of creating or managing the firewall rules designed for outgoing, incoming and inter-zone traffic.

Firewall Policy Management Tips

img

Find unused rules

Enabling unused rules to be included in a policy goes against the central principle and may pose a risk to the organization. The AlgoSec firewall management solution makes it easy to find and identify unused rules within your firewall policy.

img

Locate hidden rules

Locating hidden rules represent a remarkable opportunity to clean up or manage a firewall policy because it can improve both the performance of the firewall and the implementation of the firewall administrators accountable for managing the firewall policy.

img

Policy search

Firewall policy search is based on the source and destination interfaces. The matching security policy will indicate which actions to apply to the network traffic which includes logging and security scanning.
