ALive Computer Networks, LLC

Are you constantly concerned that your network is vulnerable to unauthorized access or attack? Let Alive Computer Networks, based out of Portland Oregon, audit your computer network for security. Below are some common suggestions:

Methods of Backup:
1. RAID drives: Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers. a. Fault tolerance is the ability of a system to respond gracefully to an unexpected hardware or software failure. There are many levels of fault tolerance, the lowest being the ability to continue operation in the event of a power failure. Many fault-tolerant computer systems mirror all operations that is, every operation is performed on two or more duplicate systems, so if one fails the other can take over. b. A Server is a computer or device on a network that manages network resources. For example, a file server is a computer and storage device dedicated to storing files. Any user on the network can store files on the server. A print server is a computer that manages one or more printers, and a network server is a computer that manages network traffic. A database server is a computer system that processes database queries.

2. DVD Backup: This is where you backup to a DVD drive, so that data can be stored off premises on a regular basis with relatively little space. There are a number of programs that allow for DVD computer backups.

3. Remote Site Backup: Some people purchase space on the world wide web to backup their data. At Alive Computer Networks, LLC, we sell space for ftp backup.

4. Tape backup: Backup to a small video/camcorder cassette.

5. USB drive backup: Currently there are USB drives that are 16G or more.

Firewall: A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. A firewall is considered a first line of defense in protecting private information. For greater security, data can be encrypted. Various firewalls include Sonicwall, Juniper, Cisco, Safeguard, etc. Alive Computer networks, LLC works with a variety of firewalls and can advise according to your specific needs.

Why do I need a firewall? Who would want my data, after all, I sell socks? Although your business may not be a target by any person or entity from a hacking standpoint; it is the untargeted, brute-force broadcasts tat hackers unleash that can cause the most serious problems. Some examples of stray packets found frequently in the logs of firewalls are Denial of Service Attacks, Pings of Death and Sub Seven attacks. Firewalls keep your network protected from unauthorized access. When you connect a computer to the public internet, you immediately become vulnerable. Firewalls restrict network access to unauthorized users, but also unauthorized applications. Our firewall security recommendations are based on network types, number of users, additional services needed (such as Virtual Private Networks).

What is a computer Virus? A program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are manmade. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.

Why do I need Virus Protection? If you have ever had a computer virus, you will know why you need computer virus protection. Viruses can cause people to put in large amounts of time and effort to get their computers operational. Some people have had to buy replacement chips or pay for a repair shop to get their systems back in operation. And some of those people have lost data they will never be able to replace. The virus threat is not going away. New computer viruses are being created every day. Some viruses are deliberately designed to damage files or otherwise interfere with your computer’s operation, while others don’t do anything but try to spread them around. But even the ones that just spread themselves are harmful, since they damage files and may cause other problems in the process of spreading.
