What is a VPN?

 What is VPN? Longmont Computer Physicians has the answer:

what_is_vpn

VPN – virtual private networking

VPN allows you to connect over the internet securely as if it is a private office network.

With a non-protected internet connection is it possible for a hacker to intercept internet data communications.   A hacker does this by going in-between the two locations and delivering a man in the middle attack to see the information. For example, a hacker can  intercept your data in a coffee shop on an insecure wireless network, using a packet sniffer program.

VPN uses a tunneling protocol.   It sets up a tunnel. Inside the tunnel it encrypts the data inside the tunnel.  So, even if a hacker can break inside the tunnel the data inside is encrypted.

vpn_tunnel_block_diagram

If the hacker does try to break inside the tunnel, the tunnel will detect it and shutdown.  It will then reroute traffic to another router thereby bypassing the attacker.

This is how VPN protects data over the internet.

The VPN is a server/client system.

Whatever VPN server you are using, you need to use the same VPN protocol on both the server and client.

The upload speed in VPN is just as important as the download speed.   Old wiring and old routers may not work well with VPN.

VPNs allow employees to securely access their company’s intranet while traveling outside the office.

VPNs can securely and cost-effectively can connect geographically diverse locations within an organization, creating one cohesive virtual network. VPN technology is also used by ordinary Internet users to connect to proxy servers. To prevent disclosure of private information, VPNs typically allow only authenticated remote access and make use of encryption techniques.

Secure VPN protocols include the following:

Internet Protocol Security – IPsec

Transport Layer Security SSL/TLS

SSH

OPEN VPN

Is my data and information secure on the internet and cloud? – Longmont Computer Repair

We often get the question “Is my data and information secure on the internet and cloud?”   The answer is NO!

Below is a letter from Brendan Eich – CTO of the Mozilla Firefox web browser which explains why this is the case:

“It is becoming increasingly difficult to trust the privacy properties of software and services we rely on to use the Internet. Governments, companies, groups and individuals may be watching us without our knowledge. This is particularly troubling when such surveillance is done by governments under statutes and laws that provide limited court oversight and almost no room for public scrutiny.

As a result of laws in the USA and elsewhere, prudent users must interact with Internet services knowing that despite how much any cloud-service company wants to protect privacy, at the end of the day most big companies must comply with the law. The American government can legally access user data in ways that might violate the privacy expectations of law-abiding users. Worse, the government may force service operators to enable surveillance (something that seems to have happened in the Lavabit case).

Worst of all, the American government can do all of this without users ever finding out about it, due to gag orders.

The Internet defined

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world.

What is the internet?

The Internet Is a Big Network of Computers.

The Internet is named for “interconnection of computer networks”. It is a massive hardware combination of millions of personal, business, and governmental computers, all connected like roads and highways. The Internet started in the 1960’s under the original name “ARPAnet”. ARPAnet was originally an experiment in how the US military could maintain communications in case of a possible nuclear strike. With time, ARPAnet became a civilian experiment, connecting university mainframe computers for academic purposes. As personal computers became more mainstream in the 1980’s and 1990’s, the Internet grew exponentially as more users plugged their computers into the massive network. Today, the Internet has grown into a public network of millions of personal, government, and commercial computers, all connected by cables and by wireless signals.

internet-diagram

No single person owns the Internet. No single government has authority over its operations. Some technical rules and hardware/software standards enforce how people plug into the Internet, but for the most part, the Internet is a free and open broadcast medium of hardware networking.

2: The Web Is a Big Collection of HTML Pages Within the Internet.

The World Wide Web, or “Web” for short, is the very large subset of the Internet dedicated to broadcasting HTML pages. The Web is viewed by using free software called web browsers. Born in 1989, the Web is based on hypertext transfer protocol, the language which allows you and me to “jump” (hyperlink) to any other public web page. There are over 90 billion public web pages on the Web today, and over 300 billion private (‘invisible’) web pages.

The Benefits of Networking with Computer Physicians

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world.

What are the Benefits of Computer Networking with Computer Physicians?

The most obvious benefit of computer networking is that you can store virtually any kind of information at, and retrieve it from, a central location on the network as well as access it from any connected computer. You can store, retrieve, and modify textual information such as letters and contracts, audio information such as voice messages, and visual images such as facsimiles, photographs, and even video segments.

A network also enables you to combine the power and capabilities of diverse equipment and to provide a collaborative medium to combine the skills of different people—regardless of physical location. Computer networking enables people to share information and ideas easily, so they can work more efficiently and productively. Networks also improve commercial activities such as purchasing, selling, and customer service. Networks are making traditional business processes more efficient, more manageable, and less expensive.

COST-EFFECTIVE RESOURCE SHARING

By networking your business computers you can reduce the amount of money you spend on hardware by sharing components and peripherals while also reducing the amount of time you spend managing your computer system.

Equipment sharing is extremely beneficial: when you share resources, you can buy equipment with features that you would not otherwise be able to afford as well as utilize the full potential of that equipment on your network. A properly designed network can result in both lower equipment costs and increased productivity.

Suppose that you had a number of unconnected computers. Employees using these computers would not be able to print unless you purchased a printer for each computer or unless users manually transferred files to computers with printers. In this scenario you would be choosing between hardware and labor expenses.

Networking the computers would give you other alternatives. Because all users could share any networked printer, you would not need to buy a printer for every computer. As a result, instead of buying numerous inexpensive, low-end printers that would sit idle most of the time, you could buy a few inexpensive printers and a few printers with high-end productivity features. The more powerful printers would be able to print more rapidly and with better quality than the less expensive ones. In addition, the more powerful printers might also be able to print in color and to sort, staple, or bind documents.

When you select the right mix of printers and assign each network user appropriate access to them, you have enough printing power to address the needs of all of your employees. Rather than leave expensive equipment idle, you provide your employees with the latest, most powerful productivity features—all for a significantly lower cost than if you were to purchase an inexpensive printer for each workstation on the network.

A network enables you to share any networkable equipment and realize the same benefits that you would enjoy from sharing printers. On a network, you can share e-mail systems, modems, facsimile machines, data storage devices such as hard disks and CD-ROM drives, data backup devices such as tape drives, and all network-enabled software. When you compare the costs associated with sharing these resources to the costs of purchasing them for each computer, the savings can be enormous.

A network also enables you to save money on software. Instead of buying separate copies of the same application for various machines, you can purchase one copy with enough user licenses for your network. In large businesses the amount of money saved on software is substantial.

Finally, you will also be able to reduce your administrative overhead. On a computer network, updates to software, changes in user information, and network security can all be accomplished from one location. With standalone computers you would be required to make these updates on each individual computer workstation.

What are Malware and Computer Viruses?

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world. 

What is Malware?

Malware is short for “malicious software.” Malware is any kind of unwanted software that is installed without your adequate consent. Viruses, worms, and Trojan horses are examples of malicious software that are often grouped together and referred to as malware.

These Are A Few Of The Signs That Malware Has Entered Your PC:

  • You start seeing an excessive amount of pop-up ads.
  • Your PC’s operating system slows down significantly.
  • The amount of spam you receive in your email increases.
  • Your email account may send out messages to your contact list that you did not send. Sometimes it contains pornographic material or even a trojan or worm.
  • The home page you have set in your browser is altered.
  • When you try to access a web page in your favorites list, another web page appears that contains advertising or content that encourages you to enter your personal information.
  • Your computer completely crashes.
  • You are unable to access your antivirus program to remove the malware.

If your computer has become unstable, that’s a sign that something’s wrong. Some malware messes with important files that keep your computer running properly. That could cause your computer to crash. If your computer crashes when you try to run a specific application or open a particular file that tells you that something has corrupted the data. It could be malware.

Does your computer seem to run much more slowly than it used to? This could be the result of malware as the malicious code begins to drain your computer’s processing resources. If you aren’t running a resource-heavy application but your computer is very slow, you might have a computer virus.

Strange messages indicating that you can’t access certain drives on your computer are another sign that something is wrong. In a similar vein, applications that won’t run or files that won’t open may also be the result of infection. Other indicators include hardware (like printers) that no longer responds to commands. While none of these guarantee the presence of a virus, they do suggest that something is wrong with your machine.

If you notice that file sizes are fluctuating even if you aren’t accessing those files, that’s another sign of a computer virus. And finally, if you access menus and their appearance is odd or distorted, you could be the victim of a malware attack.

It’s important to remember that computer viruses are one potential cause of problems like the ones we’ve listed here, but that they aren’t the only cause.

 Types of Malware

The more you educate yourself on malicious software, the better off you’ll be. Malware is not a virus. In fact, it consists of viruses, worms, Trojan horses, adware, rootkits and many other nasty infections. Some of these programs are more of an annoyance than anything, while others pose a serious threat to your computer. Regardless of the type, each of them offer their own unique security threat, and they should be avoided at all costs.

Viruses

The computer virus is the most infamous form of malware. It is a self replicating program that infects a system without authorization. A virus is often transmitted via email but can also be distributed through various storage mediums such as a flash drive. Once installed, it will execute itself, infect system files, and attempt to propagate to other systems. The impact of a virus ranges widely from slow system performance to wiping out every file on your computer.

Worms

Though closely related, worms and viruses are two completely different types of malware. Both have the ability to self-replicate and propagate by attaching themselves to files. While a virus moves from machine to machine with the help of a human, a worm tends to leach onto network traffic and can be a corporation’s worst nightmare. In no time, it can travel through the internet and inflict great damage from deleting files to creating backdoors that give its creator control of a system.

Trojan Horses

Similar to the mythical wooden horse used by the Greeks to invade Troy, the Trojan horse is a very deceptive program that appears harmless but is actually one of the most dangerous types of malware. It may arrive as a friendly email attachment or present itself as a useful application on a website. Because it does not have the ability to self replicate, a Trojan cannot be classified as a virus. However, it does have the ability to deliver destructive payloads and unload viruses, worms or spyware.

Spyware

Spyware is a sneaky program that tracks and reports your computing activity without consent. While it isn’t designed to inflict damage, spyware can terribly affect the performance of your computer over time. Spyware usually comes bundled with free software and automatically installs itself with the program you intended to use. Signs of spyware include sudden modifications to your web browser, redirects of your search attempts and the frequent displaying of pop-ups. In this instance, spyware can also be termed as adware which is essentially add-supported software that has the ability to track your activity.

Rootkits

A rookit could be a single program or collection of programs designed to take complete control of a system. This type of malware is employed by hackers and gives them all the abilities of a system administrator from a remote location.

Rootkits are very sophisticated as they make hackers very difficult to find. They are often used to infect other computers and enslave them as zombies, forcing them to attack other machines, distribute spam or steal passwords. When attempting to track a rootkit’s creator, the search usually ends with the first zombie while the hacker goes undetected.

Staying Safe

As you can see, malware is abundant and will attempt to attack your from every direction. However, there are several security solutions and system updates that will help to keep you protected. Combine these tools with safe computing and you have a much better chance of keeping the malicious software away.
