Network Infrastructure Best Practices

Corporate IT Infrastructure is significantly increasing year after year. Companies that have started with just a few servers are now upgrading to thousands of them, and there is definitely a method to the madness. Infrastructure is what runs the applications that are responsible for handling business communications and customer data, and for processing transactions. Infrastructure is very much responsible for growing companies and increasing their productivity. Due to the expansion of infrastructure, it is important that businesses take the necessary steps to secure it.

Authentication

It is crucial that you protect all of your data and information as best as you can. One way you can do this is to secure everything with strong passwords. A strong password should consist of a mixture of upper and lower case letters, numbers, and special characters. The length of the password makes a difference, too. It should be at least eight characters long. Make it something unique and something that you can remember. For added safety, change your password regularly. You can securely store your passwords through a password manager. If you have the ability to do so, use public key authentication or execute an additional security level.

Keep Your Server Clean

You should regularly delete and remove people and things that are no longer in use. This includes users and groups, software packages, and services. Limit access to these things by using firewalls. Depending on how big your business is, you should implement role separation, which means that your team members will have restrictions. These restrictions will make it harder for errors and fraudulent activity to occur. This way, your team members are only able to do what they are supposed to do for their role only.

Proper Set Up and Monitoring

It is imperative that you always know what’s going on and that you keep a close eye on things. You have to make sure that you have everything assigned to the correct users and groups in order to protect your information. Assign the right ownership and set the right permissions. Monitor the integrity of your file systems. This will help you keep on top of what is being changed, when it was changed, and who changed it. Get in the habit of regularly scanning your server for viruses and vulnerabilities, and regularly auditing your server and checking your logs. This will all help to prevent, detect, and clean out any malicious files and fix any security issues before it is too late. Encryption is a great practice as well.

Data Backup

You must always backup your data, and you must do it on a regular basis. If your server is ever compromised you will not be able to restore anything if your data is not backed up. There are various backup systems that you can choose from to create your data backups.
