Unless you’re under a rock, you know that the WannaCry Ransomware cyberattack swept worldwide headlines last week.
Organizations scrambled to apply the latest Microsoft security patch to their computers to prevent the spread of the attack. It’s estimated that the ransomware attack hit more than 300,000 victims in 150 countries.
Firewall policies are complex. Some firewall vendors try and reduce the complexity of administrating firewalls with graphical editors or zone-based administration and those concepts help. However, the reality of legacy policies, short timelines for engineering changes and staff reductions all lead to the strong likelihood that a large number of technical errors exist in firewall policies and more are being made.
Realizing this gives us a great starting point for detoxing the firewall. Let’s clean up the technical errors -- those configuration elements that could never be accessed based on the policy above. Hidden rules, obscured rules, covered up objects...all are errors in the policy that can be removed. One of the reasons that I like to start a firewall cleanup with technical errors is that there is no need to collect logs or consult the business because removing those items does not change the behavior of the firewall.
The first challenge is finding these errors. In a policy with even a couple hundred rules, the errors can be difficult to find manually. Automating the detection of these items is a good starting point and allows us to continue to monitor for errors after the initial cleanup is complete. FireMon’s Hidden Rules Report was built for this purpose.
Once we find the errors, we need to prioritize the remediation. Some errors are worse (more obvious and usually easier to clean up) than others, and there is the possibility of many errors in a current policy. Traditionally, we consider rules that are completely hidden by the policy above to be the starting point for removing errors. It’s the most obvious place to start and it can have the most impact. After we resolve the completely hidden rules, we can work our way toward other error conditions, like covered services or network objects. The Hidden Rules Report offers results in graduated levels of detail so we can see precisely the level of information we need. No more, no less.
Removing technical errors is just the first step towards detoxing your firewall. Feel free to attend our webinar to learn more.
So you’ve purchased a new firewall. Now what?
You’ve got to decide which access is allowed, which isn’t allowed and whether or not rules are compliant with internal and regulatory standards.
Things are running along smoothly and then the dreaded “change.” A user submits a new access request and the fun begins. Is this access necessary? Safe? Compliant? And what happens when it’s time to retire unused rules?
How Effective Security Management Can Help Teams Cover the Exponentially Increasing Gap between Technology & the Resources Available to Manage It
Security teams today are under tremendous pressure due to the rising frequency and impact of breaches and a business that wants to move faster and faster. The answer to both of these challenges has always been to add more technology and staff resources.
However, each new technology added creates complexity. More rules are created and more data is generated. As networks continue to evolve, this complexity will only grow. And while staff resources may increase, they will never match the exponential growth of technology.
FireMon calls this phenomenon The Complexity Gap and has set out to help security teams close it.
Join us for this webinar with Frost & Sullivan where we’ll explore the causes of “The Gap” and how workforce multipliers such as intelligence and automation help staff manage their security more efficiently and more effectively.
Helping Enterprise Security Teams Improve Resource Efficiency & Reduce Overall Risk Exposure
Firewall technology has come a long way since its initial, most rudimentary forms. Next-Generation Firewalls (NGFW) are the latest development, and organizations are accelerating adoption to the new technology. But NGFWs aren’t a fix-all solution.
