Most people know that an electric fence is used to protect the perimeters of our property and to prevent intruders from breaking in. It is no different for our computer networks. Computers and networks require effective protection through an electric fence called network intrusion prevention in Dallas. A network intrusion prevention system is capable of blocking malicious traffic by interfering in the data flow.

A network intrusion prevention system in Dallas will attempt to recognize security issues by detecting malicious activity such as bots, DOS attacks, and illicit access by thoroughly reviewing network traffic. They are installed at specific points on the network to watch the network traffic that is going to and from the hosts. Unlike a packet filter or firewall, where a packet filtering decision is made on whether or not to allow traffic to continue, network intrusion detection systems do not interfere with network traffic in any way. In simple terms, these systems could be described as a packet sniffer that also analyzes the captured packets.

If a networked computer system is not equipped with a network intrusion prevention in Dallas, the network administrators may not know that an attack or breach is taking place. They will only find out about it when their server has problems or users cannot log into their software. An example of such an attack could be where an unauthorized user retrieves password files from a login server without damaging the host. The attack may only become apparent when the intruder uses the password to gain supervisor or root privileges, by which time the system security would be severely compromised.

In an environment equipped with a network intrusion prevention in Dallas, system administrators will be notified if someone is attempting a breach. A security alert is created, and the information is collected which could be valuable in preventing the attack from happening again.
