Routers have built in console that lets you CONFIGURE different settings, like security and data logging. You can assign restrictions to computers, such as what resources it is allowed ACCESS, or what particular TIME of the day they can browse the internet. You can even put restrictions on what websites are not VIEWABLE across the ENTIRE network.

Good PASSWORDS are made up of not just letters, but by combining letters and numbers. A password that combines uppercase and lowercase letters is favorable than one that uses all upper CASE or all lower case letters. Passwords MUST be not words that can easily be guessed by hackers, such as dates, names, favorites, etc. Longer passwords are also better than SHORT ones.

Yes, that’s because MAC ADDRESSES are hard-wired into the NIC circuitry, not the PC. This also MEANS that a PC can have a DIFFERENT MAC address when the NIC card was replace by another ONE.

An anti-virus PROGRAM must be INSTALLED on all servers and workstations to ensure protection. That’s because individual users can ACCESS any workstation and introduce a computer virus when plugging in their removable hard DRIVES or FLASH drives.

In case one workstation on the NETWORK SUFFERS a malfunction, it can bring down the entire network. Another DRAWBACK is that when there are adjustments and reconfigurations needed to be performed on a PARTICULAR part of the network, the entire network has to be temporarily brought down as well.

SMTP is short for Simple Mail TRANSFER Protocol. This protocol deals with all Internal mail, and PROVIDES the NECESSARY mail delivery SERVICES on the TCP/IP protocol stack.

Encryption is the process of translating INFORMATION into a CODE that is unreadable by the user. It is then translated back or decrypted back to its normal readable FORMAT using a secret KEY or password. Encryption HELP ensure that information that is intercepted halfway would remain unreadable because the user has to have the correct password or key for it.

AUTHENTICATION is the process of VERIFYING a USER’s credentials before he can log into the network. It is normally performed using a username and password. This provides a secure means of limiting the access from unwanted INTRUDERS on the network.

This is a MODE of data exchange wherein two COMMUNICATING computers do not use IPSEC themselves. Instead, the gateway that is connecting their LANs to the transit network creates a virtual TUNNEL that uses the IPSec protocol to secure all communication that passes through it.

A large PERCENTAGE of a NETWORK is made up of hardware. Problems in these areas can RANGE from malfunctioning hard drives, BROKEN NICS and even hardware startups. Incorrectly hardware configuration is also one of those culprits to look into.

A common WAY of dealing with such a problem is to use REPEATERS and hub, because it will help regenerate the signal and therefore prevent signal loss. Checking if cables are PROPERLY TERMINATED is also a MUST.

Instead of having to visit each client computer to configure a static IP address, the network ADMINISTRATOR can apply DYNAMIC host configuration PROTOCOL to CREATE a pool of IP addresses known as scopes that can be dynamically assigned to clients.
