Security holes that’ll keep you up at night: Doing some data breach math

Over the last few weeks, I’ve taken a look at what you can do to boost your organization’s IT security. But it occurs to me that maybe I’ve put the cart before the horse.

So I’m going to spend the next few weeks delving into the sort of threats your business’s IT infrastructure faces. And I’m going to start with data breaches and the most recent big-headline example: Zappos (parent company is Amazon.com), which last month admitted it suffered a data breach that compromised 24 million customer accounts.

Automating network performance: 6 key capabilities

The right network management capabilities will provide the feedback you need to eliminate bottlenecks and IT failures while also enabling your network’s ability to deliver data, voice, wireless, Internet, and video services.

Which is why adequate performance management , trending and capacity planning , protocol analysis/ fault isolation , and onsite/remote network health monitoring have become so essential.

Is server virtualization messing up your network’s performance?

Thanks to virtualization , network dynamics are changing — fast.

Server virtualization consolidates resources on fewer physical servers in ways that require distributed workloads to communicate with each other. This boosts utilization of servers, but it also increases — and changes the nature of — network traffic.

Curing Those Security Blues

Are you suffering from security fatigue? Find yourself getting irritated when your IT folks bring up yet another security issue? You’re not alone. Lately I’ve been witnessing a good deal of security fatigue in the executive suite, and I’m not surprised.

Truth is, security remains a never-ending process. The easier we make it to move data, the more vulnerable it is to loss or theft. In fact, our Page 1 story this issue on Data Loss Prevention is all about how easy it is for too many employees to make off with sensitive, proprietary information.

Isolating and resolving network problems

When it comes to keeping your IT network performing optimally , finding and fixing network faults certainly is crucial. But it’s just as crucial to sustain network operations while the issue gets resolved.

Which means that the first order of business is to ensure that your network has entered one of the failure modes you’ve designed for it so that remaining network resources are allocated according to your organization’s business priorities.

Network performance planning: About performance baselines and failure modes

Even before you automate your network performance monitoring and management, you’ll need to do some planning. If you don’t have experts on hand, consider bringing in a reliable, dependable network advisor to help you :

Establish a performance baseline
Planning involves establishing baseline performance thresholds — called quality-of-service (QoS) rules — using historical data, estimates of how existing services will grow, and anticipated demand for new services.To determine if your plan is working, you’ll need to measure current network behavior. Such metrics include the traffic generated at certain interface points and the load levels of trunks and devices.

This is how network administrators monitor and manage network conditions. When conditions are out of whack, an alert is generated.

These alerts can indicate an emerging issue, such as a need for additional resources, or a serious problem, such as load levels so high that network and/or application performance has been impacted.
