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.
Hands up, whose firewall rules are a mess? Yes? Well, the good news (if it can be considered good news) is that you’re not alone, because 65% of your peers are in the same boat according to a survey carried out last month at Infosecurity Europe. In fact, 65% of the 300 security professionals surveyed said if their firewall rules were a teenager’s bedroom, their mom would be so angry she would ground them; and half of those said they would be grounded for life!
The same study also showed that 32% admitted they had inherited over half of the rules they manage from a predecessor – no wonder they are a mess! And a quarter of security professionals confessed to being afraid to turn off legacy rules. To add to the complexity, 72% of security professionals surveyed use two or more firewall vendors within their IT environments to try and manage rules for.
Firewall rule management can be one of those thankless tasks that is a thorn in the side of many IT managers. It takes up too much time, sort of like untangling those miscellaneous wires that have been piling up in your junk drawer.
Though organizations in general, especially IT teams, are expected to do more with fewer resources, good security management and automation can close gaps in resources while helping streamline processes and simplify tasks such as firewall rule management.
If, like the majority of IT security professionals, you’re in danger of being grounded over your messy firewall rules, here are some tips from my colleague Tim Woods on how to start tidying up your firewall policies:
Step 1: Remove technical mistakes – A primary example of a technical mistake that is classified as ineffective, incorrect and not needed is a hidden rule which includes redundant and shadowed rules that serve no legitimate business purpose.
Step 2: Remove unused access – Unused access rules bloat a firewall policy causing confusion and mistakes. To determine rule usage, you need to analyze and correlate the active policy against the network traffic pattern; doing this over a sustained period will show definitively which rules are used versus unused to help with clean up.
Step 3: Review, refine and organize access – You need to determine whether rules are justified against a defined business requirement and analyze the need vs. risk acceptance for the rule. Start with rules that employ the use of “ANY”, as these could potentially be the most risky.
Step 4: Continual policy monitoring – Don’t forget that maintaining an effective, efficient and correct firewall policy is an ongoing process. Make sure you have real-time change event monitoring and alerting and real-time audit reporting to know when a violation of your security policy has occurred.
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.
