Servers need to be secured, after all they hold a large portion of vital information and this can cause all sorts of problems if leaked. So, here are some tips to ensure your server is safe.
Having Strict Limitations
Limiting access is yet another way of enhancing security on servers. This means that the only people that should have personal login accounts and passwords should be those that really require access to the servers. Non-administrators and other casual users should only have access to the servers for a limited timeframe. Business users for instance should only be allowed access during business hours. When keying in their passwords, people need to be limited to a particular number of tries before being locked out. This ensures that hackers cannot use programs that attempt various password combinations to crack the system. Limiting access only to pre-authorized IP addresses and local IP addresses is another great way of restricting access to the server.
Using Strong Passwords
It would be useless to limit the people using the network if their passwords are not actually secure. A good and strong password needs to be not less than 6 characters long comprising of symbols, numbers, lowercase letters, and uppercase letter. It must never contain any details associated with the user including the name of the company or account.
Advise users never to share their information with other individuals, or write it down anywhere. Never send passwords via text messaging, email, or IM since all these are unsecured forms of communication. Here are some good tips.
Separate Storage for Private Information
You should keep sensitive, private data separate from the public data. Organizations and people store data of all kinds, from pictures and documents that employees use to the private data that only particular people can access. The two types of data must never share space in a single server regardless of how secure it might be. It is dangerous to leave private data out there in the open where everyone and anyone can access it. This could mean having a separate server specifically for things such as social security numbers, customer and employee data, financial records, and credit card numbers. In the end, it will all be worth it particularly when the reputation of a company is at stake.
Keeping Software Updated
Manufacturers of both software and servers are constantly updating their products and it is the duty of the server administrator to ensure that their copy is always up-to-date. It is possible and quite easy to access most updates via the Internet meaning that there is no genuine excuse for failing to download the most current update or patch. Manufacturers offer updates to their software to fix bugs and seal loopholes that otherwise might allow intruders in, so it is critical to keep these updated constantly to avoid leaving the network vulnerable.
Getting Rid Of Unnecessary Services & Default Settings
Many servers come with default settings out of the box and it is important to change these at once. In many cases, hackers gain access to servers by using default account names and passwords. This means that upon unboxing, you should change the default account login details. In addition, many of the servers today come with all kinds of bells and whistles. If you do not require or use such services, it is important to turn them off since third parties may use them to hack into the server.
However, some services are a necessity. If you are working in a harsher environment then a more industrial server can be a necessity – like this one from Chassis Plans. This will help protect your data in harsher environments.
Installation of Backup Features
Besides securing the server from attacks, it is also a good idea to install other features that ensure that the server keeps functioning in case of disasters. Server rooms and closets need to be locked always and should always have the needed physical security such as round-the-clock guards, cameras, and motion detectors. Generators and batteries on standby should also be available in case of power outages to ensure that servers keep running. Obviously, it is understood that network and data backups need to be in place always so that they are easily restored in case any problems arise.
