Network Security Testing Product Comparison
Mar 20th
Things are much different than they were 10 years ago. In today’s world, Internet applications and network systems are growing increasingly complex. There are many more protocols, languages, features and capabilities than ever before, but not only this, the amount of traffic and data being pushed across the networks have increased tremendously.
As such, detecting vulnerabilities or network weaknesses can take much longer than in the past. More importantly, hackers or malicious software are utilizing a wider variety of methods that can cripple or even compromise a business’s integrity. In the past, such attacks have been utilized to bring down even the largest corporate applications and servers.
Beyond network attacks, other common problems in the IP and networking world, are server delays, server overload, application slow down, and traffic spikes.
No one is immune to these kind of network issues, but there are powerful solutions already hitting the market that can test and eliminate most network problems much earlier than previous technologies.
Any company specializing in the protection and security of network infrastructures knows that proper testing and network emulation is one of the best ways a business can prevent network outages and application failures. Almost all network issues can be prevented with the appropriate testing, know-how and equipment.
In this article we will be reviewing the two competing network testing companies, Ixia and Spirent and their respective products.
Ixia specializes in Converged IP Performance Testing with clients in over 30 countries including Network and Communication Corporations, Electronics Manufacturers, Governments, and Enterprises.
Spirent Communications is a British Telecommunications company dealing in communications and network testing.
We got our hands on a number of products from Ixia and Spirent, namely the IxChariot, IxLoad, Ix Test Conductor, and Spirent Avalanche.
Setting Up a Small Business Computer Network
Mar 16th
A computer network setup is an integral part of every organization today. The linkage of the different computers in the office space helps in the growth of the business by saving time and money. It speeds up the work pace and invariably saves a lot of time. Each office would have its own specific needs. One can approach network consulting firms with their requirements and have a computer network setup that caters specifically to their needs. Your computer must be used to its full potential and all your needs should be met with a good computer network system in place.
An effective computer network would mean a good network design to begin with. The network consulting firms can also suggest the best possible network design as per the nature of the job of the enterprise and the role of the computer network system in the work area. There are various kinds of computer networks like the LAN (Local area network) to WAN (Wide Area Network) and various other types. Each has its own particular role and use and the right one can be chosen depending upon the field of functioning. One can even have a computer network setup that is wireless. A wireless system is a more practical solution in recent times as people can be connected and still have the option of roaming freely with their laptops. A remote access arrangement is also a good networking option. In case of the traditional wired network one should be certain that the cabling done is of superior quality or else the problems that you may end up with are plenty. A system integration firm would be the best option to setup a good network in the office space.
Network Security Degree Online – Become A Well-Paid IT Professional
Mar 7th
If you are looking for a degree that combines information technology with criminal justice – then you ought to consider the network security degree online.
Computer network security is extremely vital to all types of organizations, government agencies and even private individuals. Each year, organization lose billions of dollars in productivity when their computer systems are hacked, under attack from viruses and spam.
When systems are hacked, it is not only companies that suffer. Individuals suffer too because often times, hackers steal private information such as credit card and phone numbers.
Computer technology security measures have evolved to deal with these problems, however, so as the sophistication of cyber criminals to find news ways to continuing their criminal activities.
It is for this reason that global spending on information security, including hiring more computer security specialists, has increased. These professionals are trained on how to monitor computer systems for external attacks and to make those systems more resilient to said attacks.
Most computer security specialist received their training at campus-based colleges or universities across the country. However, there are many of them that received their network security training online. Doing their degrees online gave them privileges that
were just too good to ignore.
For starters, some of them were already IT professionals when they decided that it was time to pursue a higher education. They wanted the benefit of being able to hold on to their jobs and get their degrees at the same time. This was something that while not impossible to do at a campus-based college, is easier to achieve at an online university.
Network Security: Penetration Testing Explained
Mar 6th
A penetration test (in the IT vernacular referred to as a “pen test”) is also known as “ethical hacking”, and this network security tool provides an essential function in vulnerability assessment. By actively seeking out and deploying attacks and penetration efforts against your network, you are more likely to uncover vulnerabilities and be able to take action to block holes in your security and pre-empt attacks on the perimeter defences.
Penetration testing includes both script-based and human-based attacks on the network in order to seek out and exploit vulnerabilities. The difference between this and say, criminal hackers looking to cause mischief or theft of data, is that you control the “attacker”. The “attacker” reports back to you on whether they were successful and if so, how to stop such an attack from being successful in real-life. Penetration testing will reveal network security holes but more than this, it will be able to provide you with a realistic risk assessment including the impact on your business should such an attack succeed. Knowing what such an attack may cost your business will provide you with the ability to quantify the business risk and determine whether you do in fact, need to implement a solution.
”Black Box Testing” involves a penetration test where the attackers have no knowledge of the network infrastructure. They are working from what a real, external hacker would be using – online connectivity and any human intelligence or reliance on human nature, in order to discover vulnerabilities.
”White Box Testing” involves attackers who have full knowledge of the network infrastructure and are seeking out vulnerabilities and scenarios to take advantage of perceived weaknesses.
An intermediate form exists, known as “Grey Box Testing” where some knowledge is provided, known also as “partial disclosure”.
Network Security And Ethical Hacking – A Boon To Internet Age
Mar 4th
A group of people say that hackers are of no good to community. But we say that they are the most useful persons today on earth in the Internet Age. From when and where it started? It started from the very early age when computers were invented, i.e., in 1960′s when MIT’s Artificial Intelligence Lab became the staging ground for hackers. At that time, they were considered as persons with high mastery of computers. After then in 1970′s John Draper, most commonly known as Captain Crunch who invented making free long distance calls by blowing only a precise tone in telephone that tells the phone system to open a line. After Captain Crunch two members of California’s Homebrew Computer Club begin making Blue Boxes which were used to hack into phone systems. Do you know who the two persons were? They are two of the founders of Apple Inc. Can anyone tell what their names are? They are Steve Jobs and Steve Wozniak. In 1980′s came the main computer hacker groups who were the Legion of Doom in United States and the Chaos Computer Club in Germany. In later years of 1990′s, the malicious hackers become very powerful. In 1990′s Kevin Mitnick was arrested who now serves FBI to secure their data and has a firm known as Mitnick Securities. Simultaneously Hackers break into and deface websites which included U.S. Department of Justice, U.S. Air Force, CIA, NASA and many more. And now in late 2000′s came a new name in the field of Network Security, GM Network Security, who provides platform to people to secure their systems, networks and websites so they can be assured of lesser hacking and virus attempts than before. Some services of GM Network Security are free of cost whereas some are charged at nominal rates. GM Network Security not only provides Security Solutions but also provides Graphic Designing, Programming Solutions and also provides Training Classes for same. Not only this, it also provides Unlimited Email Space. Some tips for securing your Wi-Fi networks are always change the admin password by going to 192.168.1.1. Also put WEP security encryption key on your Wi-Fi modem.
