As a user, it is important to ensure linux server security so that data remains protected and the operating system continuous to function. This kind of operating system has an advantage because access is limited according to user accounts. There are however, many more measures you can take in order to strengthen points of weaknesses.
Reduce the amount of software or apps that you are using. While this can be great if you want some additional features, each application you install can increase vulnerability to third parties. It is best to check on the all the software you have installed and assess which ones are being used and which ones are not. Delete those that are not needed for a more secure system.
This type of system has frequent updates to help with erroneous applications and control access. Developers continue to fine tune the system and make it invulnerable against current threats. It is important to keep up with these patches and install it in the system immediately so the system remains uncompromised.
Passwords are an effective means to regulating access and preventing intrusion. These should be simple enough so it can be remembered without difficulty but complicated enough to deter those who attempt to break it. There is a minimum count of characters to be used and each one can be an uppercase or lowercase letter, number or a special character. There are tools available to ensure that users are following these specifications.
Passwords should be easy to remember and constantly updated. Each user should be required to change their password when a certain period has passed to lessen security risks. Familiarize yourself with the commands to enforce this routine.
If you have tried using the account, then you will have an idea of the extent of its access. However, since it is the known administrator account for the system, it is also the one that is most likely to be targeted. As a precaution, you should never login as the root user. Just use the standard user account and the available tools to regulate use.
Network traffic can easily be observed by third parties It is therefore necessary to protect this flow of data. One of the things you can do is to start using encryption. This will usually involve using a password or key before accessing the network.
It is a good idea to use an intrusion detection system. This is an application that helps you maintain the integrity of your system by determining if there has been any suspicious activity like port scans, hacking attempts, and so on. Use this software to do a scan before you start using your system. This application will only provide an notification and not a way to block access.
Do not dismiss the importance of firewalls to linux server security. There are two basic approaches to managing firewalls. The administrator can either permit everything and then restrict specific applications or deny everything by default and then specify the exceptions. The former is a typical setup but the second option will provide better security.
