  • To Whack or Not to Whack — Incident Response and Breach Mitigation May 21 2019 8:00 am UTC 44 mins
    Danny Akacki, Sr. Technical Account Manager, Gigamon Insight and TJ Biehle,Sr. Technical Account Manager, Gigamon Insight
    To whack, or not to whack, that is the question:
    Whether ‘tis nobler in the mind to torch all
    The compromised boxes on your poor network,
    Or to take arms against a sea of malware
    And by blocking stop them all.

    So, what do you do during an active security incident? When is the proper time to whack-a-mole with your mallet? Is it better to light everything on fire and start over, or should you make observations a key component of your response and mitigation strategy? In this webinar, we'll discuss strategies for when it's time to scorch the earth versus sit back with a cup of tea, gaining intel into what active adversaries are doing in your house.

    We’ll break down some of the most important points to remember during the commotion of an active incident response, including:

    •Context is king. We’ll explain the important questions you need to be ask when scoping an incident to get an improved view of the situation.
    •Thinking fast and slow. It’s understandable to want to nuke everything from orbit just to be thorough, but it’s usually not the smartest play. We’ll outline the potential benefits and risks of hasty containment and remediation efforts versus slow, thoughtful analysis when executing a response game plan.
    •The law of diminishing returns. There can be a tipping point where the cost of your decisions and polices no longer justify the answers you’ll find. We’ll talk you through some tactics to find the sweet spot between effort and return.
  • Network Architecture With Security in Mind May 13 2019 11:00 pm UTC 60 mins
    Matt Bromiley, Instructor and Security Expert, SANS and Sam Kumarsamy, Senior Product Marketing Manager, Gigamon
    It’s time to face a hard truth: modern enterprise networks can be extremely – sometimes painfully – complex to manage and defend. Increased network speeds to 100Gb, unfettered access to cloud applications and end-to-end encryption are just some of the requirements of today’s employees. When you add in mobile and IoT devices, the complexity grows exponentially, especially when it comes to the security of the networks to which they connect.

    And when we couple expanding networks with security needs, many organizations struggle to protect their users. This leads to conflicts between NetOps and SecOps goals. The networking team is concerned about availability and performance to ensure the business is being conducted whereas the security team needs to ensure the data and the users are safe from bad actors.

    We need a new approach that provides pervasive visibility to data flowing across the physical, virtual and cloud infrastructure to ensure that the right traffic is sent to the right security tools. This approach should also enable SecOps and NetOps to collaborate and improve the security posture of an organization

    Watch this SANS webinar to learn:
    •The common security pain points as networks expand and grow with increasing speeds
    •How today’s users are forcing organizations to consider/include security in their network architecture
    •How a lack of security can impact network availability and performance
    •How to bridge the NetOps and SecOps divide

    We will discuss how pervasive network visibility improves security tool utilization and can shorten detection and response times. We hope this webcast will inspire you to reassess the current state of your network and security infrastructure to enable collaboration between the two teams and improve your security posture. Watch now!
  • Want Better Network Visibility with Less Complexity? Here's How! Apr 29 2019 8:00 am UTC 53 mins
    Bob Laliberte, Senior Analyst, ESG and Sam Kumarsamy, Senior Product Marketing Manager, Gigamon
    Enable IT Collaboration with a Common Distributed Data Services Layer.

    The IT environment is rapidly changing, becoming more distributed and complex as organizations transform themselves to provide better digital experiences. Because these improved experiences will be more dependent on the network, it’s imperative for organizations to properly plan and prepare now to eliminate security blind spots. The bottom line is that companies need complete visibility into their physical, virtual and cloud infrastructure to detect and contain data breaches and mitigate risk.

    To accomplish this, successful organizations resist the legacy mentality that relies on more people and more tools at every location. Instead, they are turning to a new architectural approach that disaggregates the speed of the network from the speed of the tools inspecting traffic on that network. This innovative approach allows enterprises to absorb change in network speed and technology without compromising security.

    ESG believes the foundational step in this approach is to ensure comprehensive infrastructure visibility across data centers and distributed edge and cloud environments. To do this, organizations must have a common distributed data services layer that can collect, process and distribute the right information to the right tools at the right time.

    Join us to learn how a consolidated network architecture that includes security delivers better visibility, reduces complexity and increases tool efficiency.

  • The Advantages of Filtering Applications Recorded: Mar 19 2019 55 mins
    Ollie Sheridan, Principal Engineer Security, Gigamon, Brandon Dunlap, Moderator, (ISC)²
    Traditional methods of filtering traffic have relied upon a knowledge of the network and transport behaviours of the applications running across the network. Whilst most applications being run across the network use standard ports, many threat actors will use methods to obfuscate their communications by abusing these standards, with port spoofing being one such example. This represents a challenge when gathering traffic to ensure that this simple evasion method does not create a blind spot to your security countermeasures.

    Join us for this webinar to learn more about how you can:

    •Ensure that the Application traffic regardless of port spoofing gets to the right tool
    •Improve tool efficiency by discarding irrelevant Application traffic
    •Filter the traffic based on the application rather than the IP & Port
  • Erhalten Sie verlässlichen Datenzugriff für Ihre Security-Tools Recorded: Feb 8 2019 20 mins
    Daniela Fusaro, Senior Solutions Architect
    Die meisten Security Unternehmen haben viele Applikationen in ihrem Netzwerk laufen. Viele Firmen wissen jedoch nicht, welche Applikationen die meisten Ressourcen benötigen, da ihnen die volle Visibilität in ihre Netzwerkdaten fehlt.

    Security Budgets werden oft gekürzt, so dass viele Unternehmen eine Herausforderung damit haben, den erhöhten Bedarf diesbezüglich zu decken.

    Diese Ineffizienz resultiert oft darin, dass der gesamte Netzwerkverkehr von allen Netzwerk- Security-Tools analysiert wird, auch wenn das gar nicht notwendig wäre.

    Während viele Firmen den Fokus auf ihre Security Tools legen, wird häufig aus den Augen verloren, ob alle relevanten Daten oder zuviele Daten dort ankommen, die diese Tools vielleicht gar nicht analysieren können oder müssen.

    Die Security Operation Center sind jedoch abhängig davon, Netzwerk-Events zu sammeln, zu korrelieren und auswerten zu können, so dass sie potentielle Security Bedrohungen schnell identifizieren und beantworten können.

    An die richtigen Daten aus dem gesamten Netzwerk heranzukommen, und gleichzeitig die Systeme nicht zu überlasten, kann eine große Herausforderung sein.

    Application Intelligence bietet Ihnen spezifische Informationen über alle Applikationen, die durch Ihr Netzwerk fließen. Im Security Kontext ist dies besonders nützlich, weil die Security Appliances sprichwörtlich nach der Nadel im Heuhaufen suchen, um in den steigenden Datenmassen von Netzwerkflows Bedrohungsmuster zu finden.

    Sehen Sie sich unser Webinar an, um zu verstehen, wie Sie Ihre Netzwerk- und Security-Tools effizienter nutzen können, um Ihre Netzwerk Infrastruktur zu schützen.
  • Premier pas avec la visibilité : fournir des données fiables aux outils Recorded: Feb 7 2019 31 mins
    Pascal Beurel, Solutions Architect
    La plupart des équipes opérationnelles de sécurité ont une compréhension globale de ce qui transite sur les réseaux. Cependant, la majorité n’ont pas une visibilité précise des applications qui consomme les ressources. Alors que les budgets de sécurité sont réduits au maximum, les entreprises doivent lutter pour supporter une demande accrue. Les inefficiences font souvent que tout le trafic est analysé et inspecté par tous les outils de sécurité du réseau, que le traffic soit pertinent ou non.

    Tandis que de nombreux administrateurs concentrent leurs efforts sur les outils de sécurité et leurs outils SIEM, l’acquisition du trafic pertinent est souvent négligée. Aujourd'hui, le centre d'opérations de sécurité (SOC) dépend énormément de sa capacité à collecter, corréler et analyser les événements réseau afin d'identifier et de réagir rapidement aux menaces à la sécurité. Mais l'accès aux trafic approprié et pertinent sur l'ensemble du réseau et sans surcharger les outils peut s'avérer être un réel défi.

    L’approche Gigamon avec la fonctionnalité « Application Intelligence » permet de découvrir l’ensemble des applications transportées dans un réseau et de sélectionner uniquement les applications sensibles et utiles pour les outils de sécurité. Dans un contexte critique de sécurité, cela est particulièrement efficace car les dispositifs de sécurité recherchent souvent « l'aiguille dans la botte de foin»; c’est-à-dire : identifier la séquence unique de paquets ou de flux provenant de l’ensemble tu trafic et qui contient les menaces

    Rejoignez-nous pour comprendre comment tirer meilleur parti de votre réseau pour améliorer votre efficacité de vos outils de sécurité.
  • First step to visibility: Get reliable data access for tools Recorded: Feb 6 2019 32 mins
    Ollie Sheridan, Principal Security Solutions Engineer, CISSP
    Whilst many users will focus their efforts on the Tools and their SIEM tools, the acquisition of this traffic is often neglected. Today’s Security Operations Centre (SOC) depends heavily on the ability to collect, correlate and analyse network events to quickly identify and respond to security threats – but getting access to the right traffic data from across the network, and without overloading the system, can be a challenge.

    Most Security Operations organizations have a broad understanding of what applications are running on their network. However, many have no visibility into which specific applications are consuming resources. While Security budgets are stretched thin, organizations have to struggle to support increased demand. Inefficiencies often result in all traffic being analysed by all network security tools, whether it is relevant or not.

    Application Intelligence provides specific information about all the applications streaming through a network. In a security context, this is especially useful because security appliances are looking for the “needle in the haystack”; that is, to identify the one single sequence of threat packets or flows from the entire mass of network flows.

    Join us to understand how you can better utilise your network and security tools to protect your network infrastructure and ensure your end-users receive the best service.

  • Improving Security with Metadata Recorded: Dec 4 2018 62 mins
    Preetham Gopalaswamy, Senior Director, Product Management, Gigamon
    Imagine what a security analyst could deduce if they had visibility into all the common applications flowing through their network. They could optimize the data being sent to security tools, correlate information across the various protocols to know who is talking to whom and get visibility into malware and bad actors that may be hiding on the network.

    Many enterprises aggregate information from various sources, such as events and logs from DNS servers, web servers and security tools, to hunt for threat events and indicators of compromise. But these are not reliable sources; logging can be turned off inadvertently or for performance reasons. Raw network data is the ultimate source of truth – but sending it all to a SIEM can become very expensive.

    The bottom line is visibility into your application traffic is elemental to security – if you can’t see it, you can’t secure it. What’s needed is deep insight into your applications. Attend this ISC2 webinar to learn how NetOps and SecOps can:
    •Identify which applications are contributing to network traffic.
    •Use application metadata to gain more context of potential threat events and to more easily enforce corporate compliance.
    •Lower tool cost and improve tool efficiency by filtering out low-risk, high-bandwidth traffic.
    •Send suspicious traffic to a tool on-demand when an anomaly is detected.

    If you need to monitor, identify, and filter application traffic so you can more easily identify anomalies and lateral propagation of threats, you’ll want to attend this webinar!
