This document discusses security challenges in virtualized environments. It notes that virtualization limits monitoring to coarse-grained visibility, and full virtualization eliminates network visibility altogether. This hinders security, compliance, and performance monitoring. The document introduces the Phantom virtual tap solution from Net Optics, which provides full visibility into inter-VM traffic and bridges this traffic to physical security tools. It also discusses the Phantom Manager administration platform and how the Net Optics solution achieves monitoring standards in virtual environments.

What Do You Know? "In physical science the first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be.

Enterprise security teams are facing numerous challenges because of evolving threat vectors bypassing existing technology, deluge of alerts, and lack of skilled resources to stop advanced threats. Even if enterprises have a budget to bring in outside incident response and forensics teams to stop the bleeding, by then, damages and loss have already occurred. Security teams must change the shape of their security program to stop threats at the earliest and all stages of the attacker lifecycle. Join 451 Research Senior Analyst, Adrian Sanabria, and Director of Products at Endgame, Mike Nichols, talk about how earliest prevention and instant detection can change the shape and outcome of enterprise security program. This talk will outline strategies for: • Prioritizing the alerts and events that really matter • Identifying parts of the investigation workflow that can be automated • Building a detection methodology that creates confidence and continuously improves defenses

You can watch the replay for this Geek Sync webcast in the IDERA Resource Center: http://ow.ly/MzwU50A59GD Database security is arguably the most important part of an information security program that many people aren’t paying attention to. Some might assume that network or server security controls are adequate to protect databases. They’re not. Furthermore, gaps in IT governance processes often lead to security policies that aren’t enforced which can directly impact database systems. This is not only creating tangible business risks but it’s also creating numerous compliance gaps. Join IDERA and Kevin Beaver as he walks through how you can be more proactive with database security. He’ll share specific database security oversights he’s finding in his work along with some tips on how to better integrate databases into your overall information risk management initiatives.

Ransomware is typically initiated via phishing or social engineering tactics, these attacks often take advantage of human error for the successful delivery of the malware. These criminal organizations are impartial to the size of your organization. They target any company with data, and if you don't pay the ransom, your information could be posted to a public forum or sold on the Dark Web for profit. Most companies unfortunately are forced to pay due to system failure and file corruption. The scariest about these methods is that the Ransomware doesn't need to be developed by the attackers. Ransomware services can now be purchased on the DarkWeb and used at the Cybercriminal's will (RAAS). As these Ransomware attacks and services evolve, how can companies arm themselves with the right solutions to defend themselves from these evergrowing attacks? Join us in our latest webinar with Dr. Christine Izuakor (cybersecurity expert) and Jay Godse (head of product dev at Veriato).

Vendors are lured by visions of long-term residual subscription income, while customers dream of IT services and software without significant upfront costs. Sounds like techno Shangri-La, but what of security? Pessimists warn us away from the Cloud on the grounds that we should maintain control over the security of our property. Those bullish on the Cloud argue often delusionaly that your data is safer in the Cloud than on your own hard drives. Make no mistake: the Internet is the lion's den, and the Cloud sits squarely in it. This session will discuss the security realities of traditional IT software and infrastructure, and contrast them with those of Cloud-based resources.

Ransomware. The very word strikes fear into the hearts of admins, backup specialists, and security pros. Backup software vendors know if all your data is not protected, there is a good chance that if (when?) ransomware hits, you will most likely lose data. But, what should scare you more is less than half of ransomware victims fully recover their data, even with backup. What can you do to make sure you are not on the wrong side of a statistic?

Security concerns are often dealt with as an afterthought—the focus is on building a product, and then security features or compensating controls are thrown in after the product is nearly ready to launch. Why do so many development teams take this approach? For one, they may not have an application security team to advise them. Or the security team may be seen as a roadblock, insisting on things that make the product less user friendly, or in tension with performance goals or other business demands. But security doesn’t need to be a bolt-on in your software process; good design principles should go hand in hand with a strong security stance. What does your engineering team need to know to begin designing safer, more robust software from the get-go? Drawing on experience working in application security with companies of various sizes and maturity levels, Wendy Knox Everette focuses on several core principles and provides some resources for you to do more of a deep dive into various topics. Wendy begins by walking you through the design phase, covering the concerns you should pay attention to when you’re beginning work on a new feature or system: encapsulation, access control, building for observability, and preventing LangSec-style parsing issues. This is also the best place to perform an initial threat model, which sounds like a big scary undertaking but is really just looking at the moving pieces of this application and thinking about who might use them in unexpected ways, and why. She then turns to security during the development phase. At this point, the focus is on enforcing secure defaults, using standard encryption libraries, protecting from malicious injection, insecure deserialization, and other common security issues. You’ll learn what secure configurations to enable, what monitoring and alerting to put in place, how to test your code, and how to update your application, especially any third-party dependencies. Now that the software is being used by customers, are you done? Not really. It’s important to incorporate information about how customers interact as well as any security incidents back into your design considerations for the next version. This is the time to dust off the initial threat model and update it, incorporating everything you learned along the way.

Net Optics and VMware Team Up to Deliver Full Visibility, Automation, Flexibility and Scalability for Comprehensive Moni Enterprises have been utilizing Tap solutions for network traffic access for many years. Traffic capture, analysis, replay, and logging are now part of every well-managed network environment. In recent years, the significant shift to virtualization—with penetration exceeding 50%—is yielding great benefits in efficiency. However, today’s virtualization-based deployments create challenges for network security, compliance, and performance monitoring. This is because Inter-VM traffic is optimized to speed up connections and minimize network utilization. This imposes invisibility on physical tools unable to extend easily into the new environments. Costly new virtualization-specific tools plus training can affect the economic benefits and cost-savings of virtualizing. Currently, many tools suffer from limited throughput, hypervisor incompatibility, and excessive resource utilization.

To date the hype about Big Data has come from the perception that Big Data is the next frontier in gaining deeper insight into the customer, or an organization’s business. In the next decade, it is hoped (or hyped) that Big Data will be key to finding ways to better analyze, monetize, and capitalize on these information streams and integrate these insights into the business. It will be the age of Big Data. But where else will Big Data have an impact? For IT departments, Big Data represents a new set of requirements and supporting infrastructures, and will require a well thought-out approach to the datacenter network. The network will serve as the key backbone for the special communications and processing needs of Big Data. In preparation for this new era, Network Administrators should begin now to proactively plan for how to mitigate the latency and switch capacity issues that will arise from Big Data’s special needs.

ScyllaDB has the potential to deliver impressive performance and scalability. The better you understand how it works, the more you can squeeze out of it. But before you squeeze, make sure you know what to monitor! Watch our experienced Postgres developer work through monitoring and performance strategies that help him understand what mistakes he’s made moving to NoSQL. And learn with him as our database performance expert offers friendly guidance on how to use monitoring and performance tuning to get his sample Rust application on the right track. This webinar focuses on using monitoring and performance tuning to discover and correct mistakes that commonly occur when developers move from SQL to NoSQL. For example: - Common issues getting up and running with the monitoring stack - Using the CQL optimizations dashboard - Common issues causing high latency in a node - Common issues causing replica imbalance - What a healthy system looks like in terms of memory - Key metrics to keep an eye on This isn’t “Death-by-Powerpoint.” We’ll walk through problems encountered while migrating a real application from Postgres to ScyllaDB – and try to fix them live as well.
