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.
A few days ago, I was on the phone with a potential customer who was calling to see what FireMon could do to help them better manage their firewalls. Their particular concern was the performance impact their policy was having on their firewalls. Shortly into the call, they shared the information that their PIX firewall policy contained over 84,000 access control entries (rules). Are you kidding me? Of course performance was a problem, but what about security. This is not a wall, at best it is a screen door. I tried to refocus the conversation to security, but performance was their primary concern. So, I started thinking how I could better communicate the particular security concern with a policy permitting so much access.
Firewalls are designed and implemented to control access between networks. Modern-era firewalls are designed with a positive security model, simply meaning that they are designed to deny all access that is not administratively permitted. This makes adding rules in a firewall a decision to permit more access. It must also mean accepting some additional risk.
Taking a slightly deeper look into access and risk, it is clear that there is some relationship. At the most basic level, it is understood that the most secure host or network is one where there is no access (think CIA computer in a room with tightly controlled physical access and no network access). Of course there are significant usability issues in such a scenario. So, it also seems clear that permitting more access also increases the risk. Exactly how much will clearly be a factor of the threat posed by the the connecting network, but needless to say, it will increase to some degree. This relationship can be visualized in the below graph. No access presents no risk. A sharp increase in risk once any access is granted and a continual rise in risk as more and more access is permitted.
So, as it relates to the firewall, every rule that permits access also increases risk to some degree. It then seems obvious that excessive access (access that is not needed for any intended purpose) is unnecessary risk. (Clearly removing this excessive access represents low-hanging fruit of risk reduction opportunities.)
However, obviously the customer I was talking to, and in fact many organizations, have focused their firewall management activities on permitting access, not controlling risk. Focus needs to get back to evaluating risk versus access to make the firewall a more effective security device in the network.
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.
