Network Computer Security

Network administrators are surrounded today with a growing list of security risks and analysts face not only a crisis, but when accessing servers. Treatment as security risks is a daunting task and every day, as these risks is multiplied, are affecting the lives of more and more companies.
 
Cyber ​​security has yet to have worms, Trojans and viruses at bay, provided by many hackers and cyber criminals in recent years. Despite the threat of cyber-terrorism, employers and employees using instant messaging programs and highlights to download movies and other applications increase the risk of being attacked by virus.
 
Here is the list of the risk factors involved that the network security company must be protected:
 
· Email attachments-when employees open attachments, especially the unknown, allow a worm or virus to enter the corporate network. Recent worms can make their way into the system, even without clicking on a link to them.
 
· Blended attacks, viruses and worms are becoming more complicated and a single virus or worm can attack more than one platform. Read More

Computer Security

Basic computer security is essential, since the Internet is constantly expanding and as it does so do the threats of malware, virus and malware. There are many ways that hackers and well organized criminal gangs who try to infiltrate your system so you need to take a proactive role in defending your computer against these threats.
 
If you use a dial-up or high speed, you need a good firewall to control inbound and outbound traffic. The built in firewall does not offer much protection, but it's better than no firewall at all and if you have a wireless router, many of them incorporate a hardware firewall which can be set to add another level of security to your systems.
 
Some argue that with a router that does not need a software firewall, but the advantage of a software firewall is that you can easily control the incoming and outgoing traffic. If you use a router, how often do you check the router logs?
 
You need a reliable antivirus program. Most computers come with preinstalled trial versions of Norton or McAfee, but they can be a drain on resources. There are many free firewalls and antivirus programs that offer excellent protection and the option to upgrade to the pro version. Read More

Networking Career Preparation

Life without computer networks would be very different. Networks provide society with capabilities such as sending emails and transfer money online. The professionals work constantly to keep networks functional and updated. Students who wish to work with this technology have training and various career options.

Education can be obtained from colleges and universities around the country who are dedicated to this field programs. In its definition of basic computer network is to share more information when two or more computers. The most widely used network worldwide is the Internet, which is composed of thousands of connections. Students can enter training professionals at any level of education. The main areas of training include:

Engineering and Network Management
Network and Systems Support
Students learn to maintain function and support all programs that prepare them to become specialists. Each specific field provides students a centralized education. Students will learn how to work with local area networks and wide according to job tasks that go directly to their particular specialty. By gaining a strong background computer science students are able to solve the problems associated with the networks by creating plans to reduce its effects and improve systems.
Students working through the network engineering programs learn to design and secure connections between computers. Theories and technical procedures are covered giving students the ability to create, manage, and troubleshoot connection problems. A variety of computer-related courses explore how to link certain equipment for virtual private networking and routing systems develop. Internetwork programming, firewall technology, development and multilayer switching prepare students for entry-level to advanced degrees. Become network architectures and service managers are some of the possible career opportunities.Read More

Emerging Fiber Optic Data Communication Technologies

With the explosive growth of Internet users, the demand for bandwidth communication network has increased significantly.By end of 2000, there were already 29 million Internet domains and growing. Digital library, distance learning, e-commerce, video on demand and peer-to-peer sharing all are engendered by these websites.
Most backbone connections to the Internet level are backed by AT & T, Sprint and Worldcom with a standard speed of 2.5 Gbps. The network infrastructure has serious difficulties to keep up with the demand for bandwidth and that is why 10 Gbps, 40 Gbps and 100 Gbps and even being deployed and developed by manufacturers of fiber optic equipment.
Future Internet applications will create a further demand on bandwidth and switching capacity of these networking systems. With the onset of Web 2.0 applications more bandwidth hungry which is widely used graphics, pictures and videos are used. The Internet backbone has to keep up with this demand. In fact, many companies have already upgraded their networks to 10Gbps and 40Gbps. (Although still developing 100 Gbps now).Read More
