Server Hardening – A quick introduction on what it is

by | Mar 28, 2021

What is Server Hardening? Let us discuss.

All of us have a security concern for our server from hackers. If we leave it without any firewall or security system, the chances for a hack are high.

Generally, to avoid this, we tweak the server with the technique, ‘Server Hardening’.

Its major role is to ensure that all the contents in the server are safeguarded properly from hackers.

As part of our Server Administration Services, we assist our customers with several security queries.

Today, let us see how to harden our Servers.

 

Implementation of server hardening

Server hardening depends on the hardware and the applications on the server. Let us see the common steps that we can take to improve the security of the server.

  • Firewall Tweaking

A firewall controls all the access that is made to the server.

However, we can block all the unwanted ports in the server to avoid hacking and spamming.

For example, blocking port 25 will avoid spamming in the server as most of the spammers will use port 25 to send broadcast emails.

Furthermore, we can enable only the necessary ports that the applications in our servers require.

  • Regular update of all software

Since the applications we use tend to become vulnerable after a certain period, regular updates or patching is necessary to avoid issues.

For example, consider WordPress. If we do not update it regularly it will open a back-door for attackers to hack the server.

So regular updates of all software on the server are mandatory.

  • Usage of IDS(Intrusion Detection System)

An IDS regularly monitors all the files and binaries in the server on the basis of file size and time.

It will check regularly on all the binary files by matching its content with the log dump and generate an error report if the files do not match the log dump.

This mechanism helps us to keep track of all the binary files in our server.

  • Installing malware scanners

A malware scanner is a software that regularly checks on all the files in the server for any viruses and harmful scripts.

For example, the ConfigServer eXploit Scanner (cxs) helps in detecting all malware and Trojans in the server by regularly monitoring all the files in the server.

It is necessary that we install an anti-virus scanner in the server to avoid a security breach.

  • Password Modification

Make sure to regularly modify all the passwords in the server and not to use a common password for all the applications.

Furthermore, always try to ensure that the password contains a good strength above 8 keys(1 numeric value + 1 capital letter + 1 special character) in it.

Conclusion

In short, if we manage our servers without proper precautionary actions it is easy to spoil the reputation of the server. Here are a few techniques our Support Techs mentioned in order to prevent attacks on the server.
