Firewalls

Firewalls A firewall is a network security device positioned between two different networks, usually between an organization's internal, trusted network and the Internet. A firewall solution ensures that all communications attempting to cross from one network to the other meet an organization's security policy. Firewalls track and control communications, deciding whether to allow, reject or encrypt communications. In addition to protecting trusted networks from the Internet, firewalls are increasingly being deployed to protect sensitive portions of local area networks and individual PCs. The firewall solutions have additional options as encrypting, authorizations, antivirus scanning, URL filtering, bandwidth management, event monitoring. The firewalls aren't complete security solutions and must be associated with other solutions and security mechanisms for it can be a real bulletproof solution for the security of the IT systems.
