My years of experience managing security programs, across a broad spectrum of industries, has given me a greater understanding of how technology and people both play a critical role in influencing the overall security posture of any organization.
Despite being one of the older security technologies, firewalls are still the most utilized network security control in the enterprise. As Gartner noted in its last Magic Quadrant, firewalls have long provided the most cost-effective means of protecting vulnerable PCs, servers and infrastructure from external attacks to enable secure business use of the Internet. One of the many operational challenges in managing firewalls is that business units are constantly requesting new access through the firewall. While most security teams are quick to accommodate a business unit's request, very rarely do these same teams audit whether a requested access is still required 6 months, a year or even 2 years after the request is processed. Many of these requests are for a temporary access that ends up remaining in the firewall policy for years.
At FireMon, we have seen customer environments where as many as 70% of the rulebase was not being used. These unused rule can significantly degrade the performance of a firewall, and can potentially introduce risk into the environment by allowing protocols or networks access into your enterprise that are not needed. As the NIST guidelines for firewall policy state generally, firewalls should block all inbound and outbound traffic that has not been expressly permitted by the firewall policy—traffic that is not needed by the organization. Allowing unused rules to remain in a policy goes against this central tenant and represent an open risk to the organization.
Fortunately, FireMon Security Manager makes it easy to identify unused rules within your firewall policy. Within the list of devices in the Security Manager client, a user can simply right click on any firewall device, select reports and then Unused Rules Report. The pop-up box that appears allows you to specify a date range or previous number of days to show unused rules within that time frame. Users can also select if they would like the report output to be a PDF, Web Page or XML data. Clicking Finish will produce the report, which will show unused rules for both the Security and NAT rules on the device. Security Manager also enables users to setup the Unused Rules Report to run automatically on a daily, weekly,monthly, yearly or custom time frame. This automated report can also be emailed to any number of recipients. A common best practice among many Security Manager users is to have the Unused Rules Report emailed to them the 1st of each quarter showing which rules went unused for the last 90 days, reviewing the access with the business unit that requested the rule (which is identified by Security Manager using the Policy Planner tool) and removing the rule if the business unit has no valid justification for continuing to have the rule within the policy.
By leveraging this simple but powerful report within Security Manager, security managers can ensure that their firewalls are not introducing any unnecessary risk to the organization or negatively impacting the firewalls performance by unnecessarily increasing the size of the rulebase.
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.
En la actualidad, uno de los retos principales es preparar las redes de seguridad, no sólo para enfrentar las amenazas, sino también para enfrentar los cumplimientos. El día 26 de enero se publicó en el Diario Oficial la LEY GENERAL DE PROTECCIÓN DE DATOS PERSONALES EN POSESIÓN DE SUJETOS OBLIGADOS.
¿Está tu red preparada?
¿Cuentas con los procesos necesarios para el cumplimiento?
En esta era digital los datos personales de nuestros clientes y proveedores pasan por una red y se almacenan en una base de datos. Éstos, por ley, deben protegerse por medio de sistemas y procesos. Uno de los objetivos de esta ley es establecer las condiciones de tratamiento de datos personales y fomentar la cultura de protección.
La Ley de protección de datos es mucho más que un simple aviso de privacidad; esta ley describe derechos y obligaciones que de incumplirse pueden ser penalizados. Asiste a este Webinar para conocer más y prepararte. Te mostraremos:
In the fall of 2016, we sought the answer to a very simple question: What benefits do users who have a firewall management tool deployed with their firewalls see over nonusers? To find out, we commissioned Forrester Consulting to survey 188 IT security decision makers.
In their study, “Automate Zero Trust Policy & Enforcement,” Forrester Consulting found that organizations with firewall auditing and configuration tools realize more benefits that those without, including:
In this webinar, guest Speaker Josh Zelonis, Senior Analyst with Forrester, will review and discuss the results of the study with FireMon CTO Paul Calatayud who will bring his own experiences and best practices for deploying firewall management tools to improve productivity and reduce risk.
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.
