Zero Day Exploits

White Paper | Oct. 23, 2012

For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.

Your Guide to NTFS Vs. Share Permissions Best Practices

Article | Nov. 29, 2021

Most of us have heard of "oversharing" in the social sense (i.e. giving out too many details of your personal life), but how about "under sharing" in the Windows Server realm? What does that even mean? Well, I sort of just made that up, but it does actually make some sense when you think about it in terms of creating a Windows Share that doesn’t provide enough permissions.

Windows Server 2012 Features: Remote Access, Core Server, and New Roles

Article | Feb. 25, 2013

New in Windows Server 2012 is the Unified Remote Access (URA) role. In Windows Server 2008 R2, DirectAccess and Routing and Remote Access Service (RRAS) were two separate roles. In fact, they could not be co-located on the same server. In Windows Server 2012, DirectAccess and RRAS can be co-located, allowing for what is now legacy remote access VPN client connectivity (L2TP/IPsec, PPTP, and SSTP). This means that the Unified Remote Access provides DirectAccess, Remote Access VPN, and site-to-site VPN and can now serve as your complete remote access solution.

Why Upgrade to Windows Server 2016?

Article | Oct. 18, 2016

On September 26, 2016, Microsoft announced the general availability of Windows Server 2016. We already have a taste of what the user interface looks like from Windows 10.

Many other heavy-hitting server-only features will be here soon.

Why Spanning Tree Should Be Dead But Isn’t

Article | July 16, 2014

Spanning Tree Protocol (STP) is dead, or at least it should be. It’s too slow to converge when there’s a change, and it causes issues with performance because there is only one forwarding path. It was developed in 1985 by Radia Perlman at Digital Equipment Corporation to allow for redundant paths within a Layer 2 topology, which was great in 1985. In fact, it was huge! So much so, that it was later standardized by the IEEE as 802.1D, and we’ve been living with it ever since.

Why Your Company Should Have a Risk Management Program

Webinar – Recorded | April 22, 2014

Does your company have a risk management program? In this hour-long webinar, cybersecurity expert and Global Knowledge instructor David Willson will explain why you should. In light of recent breaches at Target, Nieman Marcus, Michaels, Yahoo, and a growing list of others, we're learning that FBI Director Mueller was right when he said getting breached is not a matter of if, but when. While having a risk management program may not prevent a breach, it can certainly lower the risk of one, ensure compliance, and reduce or even eliminate your liability if a breach does occur, enabling you to recover quickly and to protect your reputation. Beyond explaining the importance of a risk management program, David will tell you how to implement one, including conducting a basic risk assessment, policies you'll need, and training your workforce.

The Power of Tailoring Course Content via Private Group Training

Article | March 11, 2020

Which ITIL Processes Relate to a Data Center Operations Group?

Article | Sep. 19, 2012

I recently responded to a message on LinkedIn from a regular reader of this blog. He asked several questions which I will answer over the course of several posts. As part of his first question, he described a strategy report that his group is producing. The audience for this strategy report considers ITIL important to the future of their business, and so he must describe which ITIL processes his data center operations group works most closely with.

Where to Go Once Your Servers Are Virtualized

White Paper | March 20, 2014

The technologies examined reduce operational expenses (OpEx), not capital expenses (CapEx) that has traditionally been the focus of virtualization. Many companies implemented virtualization with the goal of saving money in the form of fewer servers to buy with a side benefit of reducing the footprint of the servers and lowering the required power and cooling. Most of the savings were in capital, but do not expect the same with many of the technologies listed here, because some may even require some additional capital expenditures, at least for software, in order to save on the day-to-day operations of IT. The bigger cost in running an IT department is in the OpEx category anyway, so savings there are recurring.

Where Does Business Analysis Fit into TOGAF?

Webinar – Recorded | May 08, 2014

The Open Group Architectural Framework (TOGAF) provides a structure for describing all transformational work within an enterprise. While TOGAF focuses on the role of an enterprise's architects, it also very much addresses the space in which business analysts (BAs) play. This can lead to role confusion, blurred deliverables, and duplicate work. In this one-hour webinar, business analysis expert and Global Knowledge instructor Adam McClellan will focus on those parts of TOGAF in which the business analyst is typically the most active, and he will outline how the analyst's work contributes to the broader architecture. He will also provide perspective for architects who work with BAs and for BAs interested in the architecture disciplines.

What Traffic Goes Into Each QoS Class?

Article | Jan. 25, 2013

This is another topic of heated debate, and it changes from network to network, but I found a simple approach that works in most cases. Since I have four queues and four classes of traffic, I need to categorize my important traffic into four classes. Strictly for explanation purposes I took some liberty in defining four categories of traffic that are very effective in both large and small networks. These classes are: Real Time Protocol (RTP), Network Management (NetMgt), Business Critical, and the Default.

What's New in vSphere 5.5

White Paper | Oct. 16, 2013

vSphere 5.5 is now available with myriad small improvements such as a faster Web Client, LACP, Autoscale and higher configuration maximums. In addition, there are changes coming such as VSAN, which may be ground-breaking in regard to VM storage of the future. Since the release of vSphere 5.5, they have not yet announced a change to the blueprint for the test. That being the case, I will say, for now, that the VCP-510 test should remain unchanged as well. My goal here is not to reeducate you on everything that you need to know for the test; instead, it is to point out the few changes that might apply in your company or organization.

What Kind of Network Am I On?

Article | March 01, 2012

Good question! There are lots of networks, so I’m sorry to say that it depends. Let me explain. The smallest computer-based networks are usually PANs or Personal Area Networks. They can connect a wireless keyboard, mouse, or other devices to a computer. You may find them wirelessly linking a printer to your computer. You may have noticed these all include wireless connections. A PAN most often uses wireless technologies like infrared and Bluetooth, so it is really a WPAN (Wireless Personal Area Network).

What is Twisted Pair and Does It Work?

Article | June 12, 2012

“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.

What is the Difference Between Bridges, Hubs, and Switches?

Article | Aug. 14, 2012

The most obvious difference is that hubs operate at Layer 1 of the OSI model while bridges and switches work with MAC addresses at Layer 2 of the OSI model. Hubs are really just multi-port repeaters. They ignore the content of an Ethernet frame and simply resend every frame they receive out every interface on the hub. The challenge is that the Ethernet frames will show up at every device attached to a hub instead of just the intended destination (a security gap), and inbound frames often collide with outbound frames (a performance issue).

What is the Cisco UCS Manager?

Article | Feb. 01, 2012

The Cisco UCS is truly a “unified” architecture that integrates three major datacenter technologies into a single, coherent system: Computing Network Storage Instead of being simply the next generation of blade servers, the Cisco UCS is an innova­tive architecture designed from scratch to be highly scalable, efficient, and powerful with one-third less infrastructure than traditional blade servers.

What is Project Quality Management?

Article | April 10, 2017

Modern quality management and project management are complementary. They both emphasize customer satisfaction and the underlying belief that quality leads to customer satisfaction. The main objective in quality management is making sure that the project meets the needs it was originally created to meet—nothing more, nothing less. In other words, to ensure quality, you must meet the needs of the stakeholder.

What Is Multiplexing?

Article | Aug. 22, 2013

Multiplexing is the technology that is able to combine multiple communication signals together in order for them to traverse an otherwise single signal communication medium simultaneously.

What is a Service Portfolio?

Article | Nov. 14, 2012

ITIL describes a service portfolio as a collection of the overall set of services managed by a service provider. A service portfolio describes a service provider’s boundaries and promises across all of the customers and market spaces it serves. I like to think of a service portfolio as describing the past, present, and future collection of services offered by a service provider. The figure below shows a high-level view of a service portfolio.

What Happens if I Have More Than One Switch With Redundant Links? Part 2

Article | Oct. 18, 2012

Now that the network is installed, each switch has a bridge ID number, and the root switch has been elected, the next step is for each switch to perform a calculation to determine the best link to the root switch. Each switch will do this by comparing the path cost for each link based on the speed. For paths that go through one or more other switches, the link costs are added. The switch compares this aggregate value to the other link costs to determine the best path to the root switch.

What Happens If I Have More Than One Switch With Redundant Links?

Article | Oct. 11, 2012

That depends on their configurations. For example: While it makes very good sense to include redundant physical links in a network, connecting switches in loops, without taking the appropriate measures, will cause havoc on a network. Without the correct measures, a switch floods broadcast frames out all of its ports, causing serious problems for the network devices. The main problem is a broadcast storm where broadcast frames are flooded through every switch until all available bandwidth is used and all network devices have more inbound frames than they can process.

What DMVPN Is and Why We Should Care

Article | April 03, 2014

According to Cisco marketing, Dynamic Multipoint VPN (DMVPN) “will lower capital and operation expenses, simplifies branch communications, reduces deployment complexity, and improves business resiliency.” Okay. But what is it, really, and why should we care?

What BI Architects and Admins Need to Know about SAP BusinessObjects BI4

Article | Jan. 12, 2016

I’d like to share some best practices for training BI administrators and architects in your organization. Because they will ultimately lead a major BI upgrade, administrators need training before a major project begins, not a few days or weeks before a go-live like other stakeholders.
