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.
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”.

Software Testing
* Dr.N.V.S.Suryanarayana ** Sheik Nisar
Software testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. Although crucial to software quality and widely deployed by programmers and testers, software testing still remains an art, due to limited understanding of the principles of software. The difficulty in software testing stems from the complexity of software.
Software: we cannot completely test a program with moderate complexity
Testing: It is the process of executing a program with the intent of finding errors.
The purpose of testing can be quality assurance, verification and validation, or reliability estimation. Testing can be used as a generic metric as well. Correctness testing and reliability testing are two major areas of testing. Software testing is a trade-off between budget, time and quality.

When to stop testing?
Introduction:
Software Testing is the process of executing a program or system with the intent of finding errors. Software is not unlike other physical processes where inputs are received and outputs are produced. Where software differs is in the manner in which it fails. Most physical systems fail in a fixed (and reasonably small) set of ways. Generally, software can be unsuccessful in many peculiar ways.
Most of the defects in software are design errors, not manufacturing defects. Once the software is shipped, the design defects or bugs will be obscured in and remain dormant until activation. Software bugs will almost always exist in any software module with moderate size: not because programmers are careless or irresponsible, but because the complexity of software is generally inflexible and humans have only limited ability to manage complexity. Software and any digital systems are not continuous, testing boundary values are not satisfactory to guarantee correctness.

First, the general view hardware information
For the card, cat, mouse, keyboard and other hardware information can be provided through the operating system’s “Device Manager” to see. Right-click “My Computer”, select “Properties” (which can also click Start → Settings → Control Panel → System open), click on “Hardware” tab, in Device Manager box, click the “Device Manager” in the pop-up set out the window, the computer will be installed on various hardware. For example, we would like to see specific information about the network card, double-click the card icon, showing that your network card installed, right-click and select “Properties” in the subsequent dialog box pops up you can see the name of the device, manufacturers, models, work status and other information, even in the “Advanced” option can also see that the hardware in the occupied system resources and interrupt request. Similarly, mouse, keyboard, modem and other hardware information is also available that view.
Second, view the CPU type and frequency of
As the heart of a computer, CPU type and frequency of performance is directly related to the computer index. Click the “Start” → “Run”, type “DxDiag” (without the quotes) and press enter, it will open a “Dirext diagnostic tool”, where the “System Information” in “at the device manager” line to show CPU type and frequency.
Third, view the memory size
Right-click on the “My Computer”, select “Properties” item, in which the “General” column will have the memory size of the show.
Fourth, see the hard disk size
Can be a very “primitive” way to draw hydraulic press hard disk size. Open “My Computer” and then view individual hard drives were the property, the size of the sum of their individual capacity, we can draw the size of the entire hard drive capacity.
