In this week’s very first bilingual episode of Engineers Unplugged, shot in Milan, Matteo Pirelli and Luca Relandini (@lucarelandini) talk about the people part of cloud. This episode is NOT lost in translation: organizational support for cloud has to be in place for projects to succeed.
The Italian Unicorn translates!
This is Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
Episodes will publish weekly (or as close to it as we can manage)
This post explains how to inspect the contents of windows DNS cache. Inspection can be used to check DNS entries, revealing if any malicious websites are being visited.
A Domain Name Server’s (DNS) cache of DNS records can be inspected to determine if your network is interacting with suspicious or malicious internet sites. To perform this task, perform the following:
For Windows 2003 and prior versions, you must install Windows Support Tools. Once installed, inspect and export the DNS cache using the command prompt (cmd.exe) window.
For Windows 2008 and later, The Windows PowerShell is a more advanced version of Windows Support Tools and is installed by default. Use the PowerShell window or run the PowerShell Script from the command prompt window to inspect and export the DNS cache.
How to Inspect the Cache from the CMD Prompt
Windows 2003 and Prior Using dnscmd
From the support tools directory (\Program Files (x86)\Support Tools), run the following command to display the DNS cache output in the CMD window.
Cisco recently announced the availability of Managed Threat Defense (MTD), an innovative managed security solution that applies real-time, predictive analytics to detect attacks and protect against advanced malware across extended networks. MTD helps our customers address the ever-changing nature of threats that threaten their most important asset—data. MTD is delivered through a cost-effective business model that allows our customers to leverage Cisco’s investment in security technology, global threat intelligence knowledge base, talent, and global reach.
To learn more about MTD, watch the video datasheet below:
While developing this solution, the MTD development team talked to dozens of customers around the world. As a result of these discussions, two dominant themes emerged:
Recently, a bug in Internet Explorer made it possible for hackers to take over a user’s computer causing government agencies to suggest using a different browser. The Heartbleed flaw opened the door for encrypted data to be intercepted. These latest challenges highlight one thing inherent to any application—whether on premise or in the cloud—it is not if but when the next flaw or bug will present exposure risks to your business. The key is to be prepared with a solid response strategy.
In two short years, 50% of Global 1000 companies will have customer data in the cloud according to Gartner. With more and more critical information moving to the cloud, IT needs to understand how cloud providers are responding to protect their data and users when these security challenges present themselves. For cloud services that IT is aware of, businesses can establish service level agreements and other safeguards to protect the integrity of their information.
Today’s security challenges are real and significant. We want governments to detect and disrupt terrorist networks before they inflict harm on our society, our citizens, and our systems of government. We also want to live in countries that respect their citizens’ basic human rights. The tension between security and freedom has become one the most pressing issues of our day. Societies wracked by terror cannot be truly free, but an overreaching government can also undermine freedom.
It is in this context that I want to offer some thoughts on actions by the US Government that in Cisco’s eyes have overreached, undermining the goals of free communication, and steps that can be taken to right that balance, and I do so on behalf of all of Cisco’s leadership team.
Confidence in the open, global Internet has brought enormous economic benefits to the United States and to billions around the world. This confidence has been eroded by revelations of government surveillance, by efforts of the US government to force US companies to provide access to communications of non-US citizens even when that violates the privacy laws of countries where US companies do business, and allegations that governments exploit rather than report security vulnerabilities in products.
As a matter of policy and practice, Cisco does not work with any government, including the United States Government, to weaken our products. When we learn of a security vulnerability, we respond by validating it, informing our customers, and fixing it. We react the same when we find that a customer’s security has been impacted by external forces, regardless of what country or form of government or how that security breach occurred. We offer customers robust tools to defend their environments against attack, and detect attacks when they are happening. By doing these things, we have built and maintained our customers’ trust. We expect our government to value and respect this trust.
