Network Security and Internet Firewalls
Today’s organizations rely on highly available, secure computing environments to efficiently and safely conduct business. Firewalls are a key component of a secure network and must be managed properly to ensure they protect your critical information assets. Network Security is involved in organization, enterprises, and all other type of institutions. It does as its titles explains, secures the network. Protects and overseas operations being done.
Network security starts from authenticating the user, commonly with a username and a password. Since this requires just one thing besides the user name, i.e. the password which is something you ‘know’, this is sometimes termed one factor authentication. With two factor authentication something you ‘have’ is also used (e.g. a security token or ‘dongle’, an ATM card, or your mobile phone), or with three factor authentication something you ‘are’ is also used (e.g. a fingerprint or retinal scan). Firewalls are configured to allow “good” traffic in and to keep “bad” traffic out. Firewalls are updated continuously to support changing business requirements such as:
Firewall management is extremely resource intensive and requires a high skill level. Because of the effort and complexity involved, a majority of firewall breaches are caused by the mis-configuration of firewall rules and policies themselves.

Network Intrusion Prevention and Detection Services
A Network Intrusion Detection System (NIDS) is an intrusion detection system that tries to detect malicious activity such as denial of service attacks, port scans or even attempts to crack into computers by monitoring network traffic.
A NIDS reads all the incoming packets and tries to find suspicious patterns known as signatures or rules. If, for example, a large number of TCP connection requests to a very large number of different ports are observed, one could assume that there is someone conducting a port scan of some or all of the computer(s) in the network.
A NIDS is not limited to inspecting incoming network traffic only. Often valuable information about an ongoing intrusion can be learned from outgoing or local traffic as well. Some attacks might even be staged from the inside of the monitored network or network segment, and are therefore not regarded as incoming traffic at all.

“Our adversaries are very adept at hiding attacks in normal traffic. The only true way to protect our networks is to have an intrusion detection system.”It also (mostly) tries to detect incoming shellcodes in the same manner that an ordinary intrusion detection system does.

Network Intrusion Prevention and Detection is a highly effective layer of security you can implement to protect your organization from unauthorized access. Many devices promise to provide this protection. However, it is difficult for most organizations to respond to alerts, apply continuous updates, hire and train staff, and provide vigilant monitoring 24×7.
