May 24, 2017 Support for Check Point R80.10 in Security Manager 8.15
FireMon customers who have Release 8.15 and have Check Point R80.10 will be able to take advantage of Check Point’s Inline Layer Policy Management. Inline Layers allow a security organization to give more engineers more access to more rules while minimizing the risk of giving these engineers access to all of the rules in a policy. For example, a network administrator can create different policies for different users.

May 24, 2017 A Practical History of the Firewall - Part 2: The Value of Management
The mid-90s was a time when networks were rapidly evolving. For example, ethernet was an option, but not always the local network protocol in use (remember token ring?). Connecting to the Internet was not assumed, it was discussed. Dial-up was still common, and AOL was the dominant player. To suggest that firewalls were mainstream technology would misunderstand the Internet as mainstream. One of the implications of this fast-changing network was a significant amount of ignorance and inexperience. In this context, the manageability of a firewall should not be overlooked as a key market driver for the eventual winner in this market

Apr 09, 2012Log Your Accept Traffic

I was watching a video from Cloud Passage earlier today about their new Beta for Windows Firewall management: Halo for Windows.  I don't mean to take anything away from their work and I think it is a good new offering.  But something jumped out at me near the end of the video that the administrator in the video only chose to log drops.  Why just the dropped traffic?

I hear this fairly frequently from people that choose to only log drop traffic, since it represent the bad traffic and they can send these logs to their SIEM to get alerts on these dropped connections.  Particularly when performance of logging is a concern and administrators want to reduce the performance impact by reducing their logging, they will turn logging off on highly utilized rules where they *know* what traffic is flowing through those rules.  But, they continue to log ALL their dropped traffic.  This is completely wrong.

Logging dropped packets does two positive things for you:

    • It allows you to verify your technology is actually working (confirming that the millions of dollars you spent of your firewall is actually doing something)
    • Identify attacks that failed

    I don't dismiss there is some value in #2, to build up a repository of threats.  And, it can aid in discovering malware inside your network and a few other good uses. For this reason, I still strongly encourage logging many drop rules. But remember, this traffic FAILED.  The preventative technology (firewall, IPS, etc) succeeded.  As for the first case, if you don't trust the technology, don't buy it.  And certainly don't use this count like a scoreboard of security success.  The fact that you successfully blocked traffic is not proof of security...no matter how many things you drop.  This is not a security success metric!

    Instead, if you care about security, you should be logging your accepts.  This is the traffic that can represent an actual risk to your organization.  This is the traffic that successfully passes through your security defenses.  There is a ton of value in this data:

      • Forensics review after a breach is discovered to learn when it started and how long it lasted
      • Threat alerts when known bad actors are SUCCEEDING in accessing resources in your organization
      • Anomaly detection when there is an unexpected spike (or drop) in typical traffic behavior

      This attitude to log all dropped traffic has been promoted by just about everyone.  Starting with the firewall and IDS vendors, who want to show value  by logging dropped traffic (look, see, I dropped another attack!).  And it is promoted by standards that say almost nothing about what a firewall policy should or should not do, but will nearly always include a recommendation to include a clean up rule and LOG it.  I don't disagree with logging cleanup rules.  But this is not nearly as important as logging successful access.  In the case of the drop, you already succeeding in thwarting the attack, the log is of little additional value.  In the case of an accept, it is worthy of some additional scrutiny.

      My suggestion...log all accepted traffic and reassess which drop rules you want to log.

      [NOTE: in the Halo example above, since it is a host-based firewall, there can be limited value in logging the http accepts to the local web server since the web server should be logging connections as well.  This video just happened to get me thinking about this topic this morning.]

      May 23, 2017 Der Countdown läuft, noch 365 Tage bis zur DSGVO (GDPR): Machen Sie Ihr Netzwerk fit für Compliance
      Netzwerksicherheit ist deutlich mehr als Cyberbedrohungen nur zu stoppen. Es geht auch darum für das Unvermeidliche gerüstet zu sein. Nämlich einen Datenschutzvorfall, den die Technik allein nicht hat verhindern können. Die EU Datenschutz-Grundverordnung (kurz DSGVO GDPR) ist, neben anderen mehr, ein solches Compliance-Rahmenwerk mit dem Unternehmen sich auseinandersetzen müssen und das im Mai des kommenden Jahres in Kraft tritt. Dann sind Unternehmen beispielsweise verpflichtet innerhalb von 72 Stunden nach einem Datenschutzvorfall darüber zu informieren.

      Apr 27, 2017 The Life of a Firewall: Seamless, Automated Rule Lifecycle Management

      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?

      Apr 19, 2017 Closing the Complexity Gap

      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.
