Overview/Description Troubleshooting skills are required by everyone who has responsibility for a network. The complexities of modern enterprise networks means that there is a vast array of devices, software, and infrastructure components that have the potential for failure - therefore causing a loss of connectivity on the network. This course describes the different networking problems and issues that can arise, as well as how they can be addressed. This course prepares the learner for the CompTIA Network+ 2012 certification exam N10-005. Network+ is sometimes referred to as N+ or Net+....

Overview/Description The choice of network media depends on a number of factors. Speed and bandwidth requirements and budgets are probably the two main considerations, although the site itself can play a part. In new construction, for example, it may make sense to install the more expensive fiber optic media rather than incurring the cost of an upgrade down the road. Upgrades to older sites can be expensive and may not even be possible in some cases. This course describes the different available network media, including twisted pair cable, coaxial cable, fiber optic cable, and wireless media...

Overview/Description A network’s security is only as strong as the security of its individual systems. Before connecting individual computers to the network, you need to ensure that the computers are secured using proper security mechanisms. This level of security will help you overcome any potential issues that might occur otherwise. Unsecured systems can result in compromised data and, ultimately, lost revenue. Identifying the appropriate steps and measures you can implement to protect your systems and keeping your resources and revenue safe from potential attacks is a key aspect of...

Overview/Description Firewalls are a critical part of the defense of all PCs and networks. Firewalls can be either software- or hardware-based, but all firewalls are intended to restrict the connections and types of connection into and out of a host or network. Firewalls can't be the only defense used to guard against the increasing number of threats to computers and networks. Additional security appliances and programs, such as IPS and IDS, port and network scanners, as well as a variety of vulnerability assessment tools should be deployed to ensure that as many precautions as possible are...
