A server is a computer program that manages or controls access to centralized information found in a network. Part of this information contained in a network is private and confidential and not meant for general public and therefore requires some security to avoid getting into the wrong hands. Below are ways in which you can enhance server security.
This can be done by restricting unauthorized access to the physical machine or hard drive. The best way to control this is by providing a strong password that is hard to guess or by installing security gadgets like Cctv Surveillance to monitor those accessing the server room or stationing security guard at the point of entry to where the physical machines are.
Permission and privileges
This can be done by reducing the number of people who can access the servers or the people with the password to log in to the servers. It can also be done by reducing the rights of people with access to servers and only leaving a few as super users. This will help to enhance accountability and improve security.
Sever developers usually deal with very sensitive data and it is important and very secure when the server is developed in a different environment from the end user. This will reduce the chances of the accidental leakage of information to the public or unauthorized party who could have interest in the data.
The major threat to server security is outdated software, frequent update of software helps to account for a potential security threat. Updating software regularly enhances server security and it is important to ensure that your server is not using the unnecessary software. If the server is using too many programs maintenance by the system administrator becomes tedious and there are high chances of missing a software update.
Use Linux Servers
Linux servers have been proven to be more secure than their windows counterpart. Linux has so many skilled programmers who work together to develop best security measures that give a quick response to any potential threat or danger.
Firewall is a barrier that prevents or limits access to the server by the general public or unauthorized party. They help to monitor the incoming and outgoing traffic to and from the server and determine if that data is appropriate.
Use intrusion detection and prevention software
Intrusion detection software is an application that detects any malicious activity or policy violation and it reports directly to the system administrator. One of the best software to use is Fail2Ban Ubuntu. It is open and free intrusion prevention software that is written in Python programming language that can protect servers from any threat. Fail2Ban helps in monitoring various log files that have unsuccessfully tried to log in a certain number of times.
Server security is important for all institutions whether big or small. It helps in maintaining the organizational information secure and ensures that only the information that is meant for the external use is accessed by the public and the confidential information is not accessible to an unauthorized party.
