CompTIA A+, Security+, Network+ Tutorial – Ethernet Card Troubleshooting

When a computer fails to communicate, the network interface adapter can be at fault, but it is far more likely that some other component is causing the problem. Before you see to the network interface adapter, check for the following problems first:

o Make sure the network cable is firmly seated into the connector on the network interface adapter. If using a hub, check the cable connection.

o Try using a different cable that you know works. If using a permanently installed cable, plug another computer that you know works into it and use different patch cables.

o Make sure that you have the proper driver installed on the computer.

o Check to see that all of the other software components required for network communications, such as clients and protocols, are properly installed on the computer. If no problem is found with the driver, the cable, or the network configuration parameters, then it is time to start checking NIC. Before you open the computer case, check to see if the NIC manufacturer has provided its own diagnostic software. If you are using a Plug and Play, you might not have even looked at the disk included with the NIC, but this is a time when it can be worth your while to do so. If the card is functioning properly, and assuming that the software providing the upper layer protocols is correctly installed and configured, the problem is probably caused by the hardware resource configuration.

There is a resource conflict between the network interface adapter and another device in the computer, or the network interface adapter is not configured to use the same resources as the network interface adapter driver.

Use the configuration utility supplied with the adapter to see what resources the network interface adapter is physically configured to use. You may have to adjust the settings of the card or the driver, or even those of another device in the computer, to accommodate the card. If the NIC is malfunctioning, due to a static discharge or a manufacturer’s defect there is not much you can do except replace it. Before you do this, you should check to see that the NIC is fully seated in the slot, as this is a prime cause of communication problems. If the card is not secured with a screw, press it down firmly into the slot at both ends and secure it. If the problem prolongs, try removing the card from the slot, cleaning out the slot with a can of compressed air, and installing the card again. If not, you can try using another slot. After exhausting all of these avenues, trying installing a different card in the computer, either a new one or one from another computer that you know is working properly.

Network Security Management Services

Network security is to secure both public and private computer networks, used every day to conduct transactions among businesses and individuals. Any business related to IT network system needs to make sure to establish a strong, secure network for their data and systems. There is an increasing need to secure your networks within organizations. To achieve network security, all requirements have to be met to use networks securely.

Organizations spend a large amount of their business on IT network security. It is necessary that networks themselves have the appropriate levels of security. An effective and valuable network security strategy requires identifying the threats and choosing most effective tools to struggle them. Email security management and Antivirus security are effective services in keeping a critical data and communications safe from intruders or attacks and other threats to security.

Email security management

Email viruses through harmful attachments in the emails can reach your system and infect it. Email security management helps to stop unwanted materials and reduce spam in emails. It also provide message tracking capabilities in order to follow e-mails for troubleshooting and auditing purposes. It also helps in examining the security threats facing your corporate email system. Email security management gives you the reliable email security performance and safeguards your important emails against all threats.

Secure, Network Compliant BYOD Solutions Are NOT a Myth

In a recent article featured on Forbes.com, Bring Your Own Device (BYOD) is described as an inevitable component of the evolving office ecosystem. In the same article, a statistic borrowed from an IBM study & reveals that 81% of organizations reported their employees are using their personal mobile devices to connect to “company resources”. If you are an AV integrator or the head of IT, this statistic probably conjures fears of rampant network security risks.

But BYOD doesn’t necessarily equate to network security problems. Based on the current trend of using mobile devices in the workplace – secure, network compliant BYOD solutions are almost certain to arrive in the very near future. It is up to technology innovators to meet the market demand by developing, testing, vetting, and integrating the products to keep up with the trends we see around us. In short, embracing the changing workplace dynamics – and the products that support them – is likely the only way forward.

Like any other disruptive trend in technology, there are growing pains in the adoption phase. One of the biggest growing pains for BYOD in the workplace is security. So what does a secure BYOD solution look like?

We have identified 3 key criteria for secure, network compliant BYOD solutions.

1. Routable TCP/IP Traffic with Adjustable Base Ports

The complexity of many corporate and campus networks is often matched only by their uniqueness. After all, the many subnets and VLANs included on the enterprise network were set up to serve the unique requirements of the specific organization. Therefore the likelihood of any other enterprise having the same network setup is infinitesimally small. This is why it’s so important that BYOD solutions that hit the network feature routable TCP/IP traffic with adjustable base ports – so the solution can be configured flexibly to fit the network without creating additional, unnecessary work for the IT department. This is also important in order to avoid violating IT policy, which could prohibit the deployment altogether.

2. Controlling Access from all those Devices

Another security risk associated with BYOD revolves around the regulation of access in the workplace once these devices are supported on the network. To use a common use case as an example, if a wireless BYOD presentation is taking place in the conference room, how do you prevent uninvited users from sharing content to from their device and disrupting the meeting?

For this reason, access control is our second criteria for BYOD solutions. A solution to this challenge would be to offer multiple access modes that can be set in-room or remotely. Access could then also be locked by an admin or left up to users in the room to determine when beginning a session. Additionally, access control options could be dynamic, which means they could be changed during a meeting without interrupting the flow of information posted to the shared display.

In addition to these modes, it would be ideal if any session could be closed once all in attendance have joined. This combination of access control options creates secure access for nearly every type of meeting and use case.

3. Remote/Centralized Management

It’s a hard truth that nearly all technology crashes at some point or another, and those crashes can lead to big issues for the IT department and the network. That’s why remote/centralized control is such an important factor for BYOD solutions, especially large deployments.

Not having the ability to monitor, configure, and update BYOD solutions on your network from a remote/centralized work station makes larger, more complex deployments difficult to manage. Ideally, there would be a way to support remote/centralized management of every instance across the network. Network administrators could then monitor, configure, and update settings for any/all instances from their workstation anywhere on the network.

With BYOD becoming a standard in work spaces, security is and will remain a paramount concern and consideration for evaluating new solutions. The best solutions with work with your existing network and make it (relatively) easy for your IT department to securely deploy, monitor, and manage the system. BYOD presents many inherent risks, but many of these risks can and should be addressed by solutions that work within secure network environments.
