The best intrusion detection system is one that lots of people would like to own. The government itself has probably been contracting out to find the best intrusion detection systems on the market, though this might come with mixed results. As of 2013, the US government has spent as much as 13 billion USD on information technology defenses.
Even so, in 2011, there were well over 40,000 incidents where people lost data to theft and we saw a breach of security of one sort or another. It is for this reason that people are building firewalls all the time. Having the right network firewall in place can go a long way toward protecting a networked computer from having the same negative effects that it would have encountered on the internet.
Today, more than half of all businesses do not understand what is involved with a security breach and it is for this reason that security breaches will be on the rise until people are capable of parsing out all of their implications. That being said, the organizational cost of a security breach has declined in the past two years because people have gotten better at cleaning the breaches up.
Nonetheless, a network security company can go a long way toward providing the very services that people need to ensure that their software is taken care of. It is for this reason that the best intrusion detection system is the system that can help people take care of their products.
Building a firewall is a complicated business and it is for this reason that people will continue to look for the right security settings. They need to be proactive about this, because the people who are seeking to steal from them certainly are. See this link for more references: www.sourcefire.com
