How To Add Network Security Features

Corporate networks in business contain crucial data and require the latest network security to prevent exploitation, port scanning, data corruption, hacking intrusions and viral infections. Administrators must be updated in adding network security features that are necessary to protect the data, the entire system as well as the entire software investment of the company. The administrators must run intrusion tests from other external networks to assess the network security by using access tools. After such tests, the appropriate network security features are then installed.
To test the strength of a security of a particular network, one must apply software that detects the soft spots or penetrable parts of network. These are commonly referred as network security penetration tools. The weak points are scanned using these special programs that search for probable openings. The first thing you need to consider is using a tool such as the Kismet. This sniffing program is used in any platform such as Unix, Linux, Windows and Mac. It is very powerful in detecting wireless networks within a range depending on the antenna. You can also use a similar tool such as the Net Stumbler.
To intentionally barrage your existing network security, you can use a Linksys version of Kismet to acquire readings of the current signal strength, security type, IP channels and MAC address from an external computer. Kismet would indicate that a particular network is open or vulnerable to outside entry. Otherwise it is locked and secured on all fronts with WAP port encryption.
Another network security access tool to consider is the Aircrack. It is the fastest available WEP and WPA cracking tool, deeming most password encryption useless. With updated Linksys software, Aircrack can break the barrier of the security by decrypting the password. This enables any intruder to gain passport entry. Gaining access into a secured network through a wireless router is a remote possibility. Thus, it provides the user the choices and options about the details of a particular network and the possible points of entry.
Another malicious network security is the THC Hydra. This neat program uses brute force to analyze a remote password authentication service. It uses a password file that contains millions of passwords, each one has a good chance of being a key for unrestricted access into the network. However it features a command-line interface, which poses as a problem with the novice.
When the weak spots are identified, the network administrator must reassess and evaluate the frequency of security attacks and perform checks to avoid the risks of compromising the integrity of the network.
One of the most promising network protections online is Trend Micro Smart Protection Network. They defend your network with threat correlation and threat intelligence systems. Threat correlation is the analysis of not only one activity of security attacks but it analyzes a combination of malicious activities made against your network. Trend Micro goes beyond antivirus protection and data back-up. Their online experts link your network with their systems and records activities that are suspicious and subtly unknown to your supervision. Trend Micro has features such as filtering of incoming data and buffering data entry points with unique reputation technologies as part of its analyzing system. Malicious URLs, spamming domains and malware files are checked and blocked while ensuring the optimal functionality of the whole network. Through the correlation of the failed network entry and malicious data coming in, Trend Micro ultimately identifies the source of the attack and gives you immediate protection from all attacks.
