Security and Firewall A firewall is a system for monitoring and blocking unwanted communication via the network which is connected to server. The firewall is an important component in securing the server. There are two main configurations of firewalls: software firewall and hardware firewall. Firewall secures the server in several ways: - Monitoring and limiting access to applications and / or specific visits todedicated servervia the Internet. - Internal security settings of the server (This option allows setting of various restrictions on the internal network versus external internet). - LOG - log is a list in which all events that occur on the network and server are recorded. The log enables convenient and efficient monitoring of unusual events. - Permissions - The "rights" of access to the...

Server Monitoring When mail servers or any other server crashes, or even a partial crash, the immediate effect on the loss of efficiency, service level, customer satisfaction and eventually - the amount of financial, losses is enormous. Therefore it is important to monitor the server continuously - 24/7/365. Monitoring services allowthe reduction of the server downtime, and optimizethe response time and troubleshooting. Since monitoring services useadvanced systems that alerts in real-time, most of the times you will not notice the malfunction before it is handled by support staff, thus it is important toprovidea continuous activity of 99% Uptime.

Hardware Features The main features of servers hardware are divided into three parts: CPU, memory and hard disk. The processor intensity and amount of cores The processor is the 'brain' of the server. As the number of computational operations per second, rises, the greater the need for a powerful processor. It is recommended to always invest in a more powerful processor, due to rapid technology development. The importance of the cores number Multi-core processors (DUALCORE, QUADCORE, I7) enables the running of multiple applications and software simultaneously in maximum speed and efficiency. Operating systems such as Windows, Linux and Macintosh OS are making effective use of multi-core in order to run multiple applications simultaneously. Lack of cores, causethe operating systems to subdivide CPU time...
