Dynamic Host Configuration Protocol (DHCP)

What is DHCP?

A protocol is a set of rules used to determine how computers on a network communicate. The Dynamic Host Configuration Protocol (DHCP) is a protocol commonly used to automatically generate an Internet Protocol (IP) address and other configuration details, like the Domain Name System (DNS) server address, subnet mask and default gateway to client host computers connecting to a network.

Before it can connect to a local or internet network a computer, or any other device, needs to be properly configured to communicate on the network. With DHCP the configuration takes place automatically instead of manually, and as a result DHCP is often used with numerous devices that connect to networks, like computers, smartphones, servers, etc.


Common Types of Malware and how to Avoid Them

Malware is a catch all phrase that includes any sort of program designed to do harm to a computer or that disrupts its normal processes. This includes viruses, spyware, adware, and much more. Malware is one of the biggest enemies of any computer that has access to the Internet, be it a company computer or a personal one.

Remote Administration Tools are also known as RATs. If you have a RAT infestation, it means that somebody has planted malware on your computer that will give a remote user administrator rights to your files. This can include gaining access to your personal software as well as some hardware like your computer's microphone or webcam. Essentially, anything you can do with your computer, somebody using a RAT can as well. This malware is usually spread by getting users to click on a link that they think is safe, especially via social media channels or file sharing networks. You should make sure to avoid any unknown files or links, as a single mistake can lead to a RAT infestation that can destroy your privacy.


Pros and Cons of Windows Remote Desktop Services

The Windows Remote Desktop Services, or Windows RDS for short, is Microsoft's remote desktop tool which is customized specifically to the features of Windows in all its various iterations.

This is ideal for businesses, especially if you have a centralized file storage but have employees who do a lot of traveling or who work from home. Because the technology was developed specifically by Microsoft, it has a great deal of compatibility with Windows and takes advantage of some special Windows only features. You can generally expect this system to work with both 32 bit and 64 bit applications on Windows, although you may have some compatibility issues when it comes to the remote access of certain third party products and programs.

The use of both can help you to secure your software and also enable remote distribution to many different users in a simple manner.

Guide to Virtual Private Networks

Imagine leaving your home wearing a clearly legible sign around your neck that provides all of your most important and private information: your name, address, contact information, banking and other financial data, all of your shopping habits, places you frequent and what you do while you are there. Most of us would not want to share this information with complete strangers, for many obvious reasons. This data can put you at risk in any number of ways, including potential theft and physical harm. Yet, that is exactly what many people do every time they use internet.

When individuals and businesses use the internet without encryption they leave all of their information out in the open, and put themselves at great risk. A virtual private network (VPN) can ensure the security of your connections and your most important information. A VPN utilizes a public network (most commonly the Internet) to link distant sites or users. In the past computers had to be connected via hardwiring. A VPN uses "virtual" connections directed through the Internet from the individual or organization’s private network to the distant site or employee location. There are several advantages to using a VPN. As shown above, a VPN can be used to establish a secure connection to a remote network using the Internet. Many businesses use VPNs to enable employees to access to files, software, hardware, and other company resources. Individual users can also utilize a VPN to safely access their secure home network from a remote location.

VPNs are extremely useful to organizations that need to securely connect several networks. As a result, businesses of nearly every size depend on a VPN to connect and share servers and other assets between multiple locations around the world. Individuals can also utilize a VPN to connect their home or additional networks for personal use.
