Network Security at Work

January 14th, 2010



If you have a small business with a few workstations at the office, you’ll still need to take active steps in protecting your network. After all, you’ll never know what any of your employees could be up to while surfing the net. Although they wouldn’t will it to compromise the security of the network nor your business, some of them unknowingly do so due to lack of education. They may think there’s nothing wrong with clicking a link on a spam mail they got when that link would have linked them directly to a hacker’ s website. In other words, there has to be a way for employee’s browsing habits to be monitored and observed in order for your network technician to know what dangers he may be up against when it comes to keeping the network in good shape.

Moves to protect a network definitely need to be fully functional, which means they must not leave out any chance for the dangers to find their way into the network. There has to be an administrator who will be in charge solely of keeping it clean and working well. Sometimes, small businessmen take this for granted, not realizing that one false move by an uneducated or reckless employee can get all computers on the network to crash. Definitely, the administrator should be consistently what people using the network are using it for. There must be clear guidelines on the use of the Internet. In fact, Internet usage that is not directly related to the job at hand must be banned altogether to reduce the risk of compromising the network’s security.

Another step a businessman can take is to have network security experts conduct a seminar within the office to be attended by all network users. People usually put their computers or networks at risk due to the absence of knowledge about these risks. By carefully taking the time to inform employees about the dangers associated with certain Internet activities such as file-sharing using peer-to-peer sites and downloading software whose integrity is unknown. When people are aware of the presence of threats, they would usually take it upon themselves to be more careful an d conscious of their Internet activities in the future, unless the intention is really to compromise the network.

Of course, to make sure that important files are never affected and always accessible for retrieval in case problems with the computers or the network come up, it is recommended that all of such files be safeguarded with backups on a remote access server site. You’ll never know when a bug begins to strike and wipe out your entire hard drive. Just to not leave anything to chance, which could mean too great a loss, it is important to have backups all the time.

In terms of prevention of online risks, a good move would be to install an IP changing software. With this program, anyone on the network is able to surf the web with their IP address hidden. And when the IP is hidden, so is that link between the hacker and his victim.

A+-Network+ Training and Certification

December 11th, 2009



A+ certification is possibly the most popular way of breaking into the computer tech business, as it demonstrates basic competency regarding computer hardware and software. Offered by CompTIA, the certification involves taking two tests: the A+ Essentials exam and a choice of one of three elective exams: IT Technician, Remote Support Technician, and Depot Technician. The knowledge base required involves understanding how to take apart a computer and put it back together, how to build a computer from its basic components, knowledge of the purpose and function of component parts such as the motherboard, CPU, display devices, power supply, and cooling system, among others.

In addition, on the software end, the A+ certificate seeker is required to know all about modern operating systems. While CompTIA is vendor-neutral, it emphasizes knowledge of the Windows operating system, because A+ certification is designed to produce computer technicians who can make a living, and Windows holds the lion’s share of the OS market. However, the certificate seeker is still required to have a basic understanding of Apple and Unix-like operating systems. He or she is required to understand the boot process as well as the basic framework of multiple operating systems, so that he or she can provide adequate support to customers needing assistance.

Regarding Network+ certification, the basic premise is the same as that for A+ certification, except it is required for anyone who wants to be an IT network technician. The certification shows that the successful Network+ candidate is able to maintain, configure, install, troubleshoot, test and manage all sorts of network infrastructures, has an understanding of modern networking technologies, basic design principles, and grasps modern wiring standards. In addition, the Network+ certificate seeker benefits from having the A+ certification since Network+ requires the same technical skills as a foundation. Networks contain multiple computers, as well as the nexuses between them, so it’s far trickier to troubleshoot than just a single computer.

The specifics involved in the Network+ test involve knowledge of common networking protocols, both wired and wireless, as well as an understanding of all the hardware involved in creating a network. He or she must know how to set up a fast and secure computer network utilizing firewalls, routers, and switches, and ensure that it is free of viruses and malware. The certificate seeker must be familiar with all the tools of the trade, as software-based and immaterial as packet sniffers and port scanners or as gritty and hardware-based as cable-strippers and temperature monitors. He or she must be able to diagnose problems and have adequate knowledge to come up with a solution.

Any job with a major technology company involving technical expertise will require A+ certification, and if you’re looking to be a network or systems administrator, Network+ is increasingly necessary for your career. Many major corporations, such as Microsoft, Cisco, Novell, and HP, include the CompTIA Network+ and A+ certification in their mandatory training requirements.
