In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

5 Secure Switch Management Best Practices

March 29, 2012 09:01 AM

One of the easiest things an organization can do to help increase the security posture of their infrastructure is to implement a policy and standard for secure management. Often overlooked, or not fully executed, this is what I consider to be the low hanging fruit of network security.

F5 Networks 'Fixes' Data Center Security

January 24, 2012 11:00 AM

Arguing that multiple point appliances intended to secure a network only add to complexity without providing the intended protection, F5 Networks is introducing what it calls a Data Center Firewall to combine multiple security solutions into one appliance. The appliance, called BIG-IP model 11050 and carrying a starting price of $129,995, delivers such security features as dynamic threat defense, DDoS protection, protocol security, SSL termination and a network firewall.

Convergence Protects Against Fraudulent Web Security Certificates

November 03, 2011 10:39 AM

Recent problems with certificate authorities have exposed major problems with the trustworthiness of Web browser security. Rather than simply trusting a signed SSL certificate, Convergence, a free Firefox extension, checks with several trusted certificate sites, or notaries. If all of the notaries agree that the certificate is accurate, Convergence gives the go-ahead to use the site.

Certificate Authority Compromises Are Global In Reach

September 09, 2011 01:48 PM

There has already been a lot written about the compromise at DigiNotar, GlobalSign and Comodo. One day we will look at the summer of 2011 as the time when the PKI collapsed. That's not hyperbole. The problems with certificate authorities and the inherent weakness they present have been known for years--a fact we alluded to as far back as 1997. Browsers accept certificates as trusted in that they have the signing CA certificate in their local browser store. Browsers do not check that a particular CA is authorized to actually issue a particular server certificate. The trust is universal. That is why the attacks on DigiNotar, GlobalSign and Comodo are so serious and have global impact.

GlobalSign Puts Holds On New Certificates Pending Security Investigation

September 07, 2011 10:09 AM

After boasts by the Comodo hacker that he'd compromised GlobalSign, the certificate authority (CA) on Tuesday announced that it would temporarily cease issuing any new certificates.

Certificate Authority Hack Points To Bigger Problems

September 07, 2011 07:00 AM

What with hurricanes, earthquakes and Kardashian weddings dominating recent media coverage, you may have missed the news about a recent security breach that clearly displayed a serious weakness in one of the core security mechanisms of the Internet.

ExtraHop Addresses 2,048-bit SSL Decryption Performance Penalty

June 07, 2011 08:00 AM

It's still early days for 2,048-bit SSL (Secure Sockets Layer) encryption/decryption, but privately held ExtraHop Networks, a specialist in network-based application performance management (APM) solutions, is betting it won't take long for the significantly more secure standard to be adopted, with major implications for application monitoring. The next step up from 1,024-bit encryption is approximately 4.3 billion times more secure, requiring 4 to 8 times more computation for each decryption.

Tenuous Chains Of Trust In Digital Certificates

March 24, 2011 12:00 PM

Hot on the heels of RSA suffering an attack of unknown origin and resulting in a loss of unknown data with an unknown impact, news that certificate authority Comodo issued nine fraudulent certificates that browser vendors and OS vendors have had to issue a patch for highlights the fragility of the security systems that protect your data in transit across the Internet. In Comodo's case, neither the root CA nor any of Comodo's systems were compromised, according to its own incident report. Rather, one of its customers, a registration authority, was compromised. It appears the compromise was quickly caught and Comodo started working with vendors to get a fix in place. It's time to once again question whom we trust and why.

Releasing Firesheep: Right Intention, Wrong Action

October 25, 2010 04:57 PM

Eric Butler released Firesheep, a Firefox extension that makes stealing others' Web sessions trivial. Firesheep steals the cookies associated with a user session and then uses the cookie to let you, the attacker, start a new HTTP session impersonating the victim. It's trivial. All you need is to be able to sniff the traffic over the air or off the wire. I spent all of 3 minutes downloading and installing Firesheep before I hijacked my wife's Facebook session. It also works on other common social media sites such as Twitter and Yelp. You can also add new sites that use session cookies. Butler said he released Firesheep to shine a light on a prevalent problem. I agree that session stealing, aka sidejacking, should be addressed. But releasing a tool my grandmother could use is irresponsible.

Entrust Introduces Publicly Trusted Secure E-mail Certificates, Adds Powerful Functionality To Extended Validation, Unified Communication SSL

August 17, 2010 09:58 AM

Expanding on an already impressive digital certificate portfolio, Entrust, Inc., adds publicly trusted secure e-mail certificates to its certificate management service, enabling digital signature capabilities and encryption of e-mails and other documents. The managed certificates provide a cost-effective approach for individuals or organizations to secure important communications.
