Protection is priority. Modern high-technology offers endless potential of development and numerous possibilities. Nevertheless, where potential development is there also possible threats can be found. In case of computer surroundings such threats are most often attempted attacks that can be detected but if there is no stable and effective protection system installed the attack will succeed. Once a vicious attack is launched there is high risk of data loss. The nature of a particular attack is dependant on the aim. If the aim of attack is to intervene with normally performed operations, the risk of permanent data loss and possible damages is the highest.
Other attacks are aimed at data itself if the intruder was determined to launch a computer attack in order to use data without any permission. In such situation, the intruder may remain hidden yet active. It is uneasy to detect such activity with no professional tools such as a firewall. Regardless of the general tendency to repair rather than prevent, it is always more reasonable to protect computer no matter if it is used in a company or at our home. In fact antivirus is not enough to ensure all levels of computer and data safety as only a firewall can literally detect danger and not allow it to enter the system. While antivirus detect danger once it occurs, a firewall is the first line of defense.
Numerous firewall version are available and thus, it is easier than at any other time to choose a firewall that will be the most effective from our perspective. As far as firewalls are concerned, there are certain features that every professional firewall should possess. First of all, high safety level requires real-time or near real-time update as new viruses and other malicious applications are being created. Such feature can be found in models of Cisco Firewalls as Cisco attaches supreme importance to safety.
Productivity and capability of development are another crucial values that must be possessed by a router effectively performing all operations that it is responsible for. High productivity and capability of being expanded are useful for any potential client who is found of alternations as well as in business surrounding.
Generally, firewalls, including of course Cisco Firewalls are capable of controlling firewall application, preventing hackers’ attacks, forming IPCom protection, creating SSL and IPsec connections, maintaining Channel capacity control at the level of 450 Mbps and finally, professional firewalls such as Cisco Firewalls can be activated and deactivated on demand.
