Dual Security with Added Intrusion Detection System
An Internet Security system is necessary as many online users without firewall protection whose PC’s are connected to the Internet would not survive virus attacks and other threats. Enabling a dynamic network security is thus essential for them.
In order to safeguard the system, it is crucial to install and configure a detection system before getting online. Install windows XP services Pack 2 or windows vista and use built in firewall while shopping for a robust firewall. A combo set of hardware and software firewall renders an extra layer of security. Hardware firewalls are stronger when it comes to resisting attacks and a single hardware router can protect every computer on your network.
Such firewalls are effective irrespective of little or no configuration; however they lose out in securing outbound traffic. Hardware firewalls can block all outbound ports and keep only your port 80, 110 and 25 open, but they look at all outbound traffic as safe, which in some cases might not be true. Take a look at this situation when its own SMTP services are infected and are sending out mail on port 25. Hardware firewall security system allows it without any disruption since it takes all outbound traffic legitimate. In that case if one had configured only outlook to use port 25, attempts by intrusions to enter your PC can be blocked and an alert is generated thereafter.
The downside of intrusion detection software is that it is required to be installed and configured in every system one wishes to protect from intrusions and threats. It may be expensive or time consuming if it is to be installed in large number of computers; at the end of the day, it is imperative to make sure that your system is secure. Most firewalls provide essential features such as access points and broadband routers have a built in firewall, which protects systems from plug-ins. Since malwares are malicious or unwanted software such as viruses, Trojans, browser hijackers, spoofers, redirectors and hoaxes, which are created for all the wrong reasons.
There are different firewalls and antivirus programs available online, which are exclusively designed and created to minimize risks of being infected and influenced by malicious objects. Some of the major softwares have already outranked some of the popular commercial softwares. In conclusion firewall softwares offer plethora of protection features such Trojan horse programs and viruses while hardware firewalls offer excellent general protection against hacker attempts to infiltrate your system.
