Strategies to Keep Your Servers Safe


Most of us understand the important of security. But mainly we care about physical items. But it is not the only thing that needs security. Data security is as valuable as physical security. Business information, intellectual property or client data are few examples for it.

Physical properties can be locked in a room for security. But the data cannot be made safe that easily. At least if it is in a computer, firewall or passwords can give some sort of protection. But if it is in a server, it becomes really risky unless it is well protected. There are some basic measures to be taken when the data is stored in a server.

There are actually firewalls installed in servers as well. Main thing is it has to be active and if the network access is there to the server, network firewall is required. This will control data transactions between networks depending on the trust level of them.

Harden Your System

There are many precautions to take in order to minimize the risk involved with servers. One very important method is to harden the system. There are many ports in a server. But generally few of them only will be used. Others will be left as it is. These unused ports will be a real threat to the server. They can give lots of chances for other parties to get access to the server. That is why it is very important to turn off al the unused ports and harden the system.

Another effective way to reduce attacks to the servers is by removing all the unused software from the server. Soft wares will give lots of opportunities for the attackers to get into the system. Specially concentrate on office and entertainment software. Removing unused software will reduce the probability of attacks to the server.

For a multi server system, it is advisable to have a separate server for a separate task. Then only one task will be handled by a single server. So it requires only one port as well as few soft wares, which makes the server safer. In the case of large scale companies, this will be a possibility.

Other than these measures you can strengthen the security with strong passwords as well. These passwords should at least have 15 characters but not only letters or predictable words. It is better to limit the access to the server for visitors. Be careful while executing exe files as well.

Audit Vulnerabilities

Hardening is a process which has to be carried out very efficiently. After hardening the system, it is better to audit it to find any more flows in it. There may be some undetected important parts which need to be covered as well. The Center for internet security has many tools to audit the system. They can be downloaded free and they will audit operating systems, applications as well as network devices.

It is not important to just install all these security measures. They must be updated regularly and also routine scanning has to be carried out. Security maintenance plan should include getting latest patches for the security soft wares. This will keep away the latest threats that have come into the networks.
