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.
Look out for the latest upgrades as these may involve security patches that can fix glitches in your system. This kind of operating system usually put out frequent small upgrades and it is best if you install these upgrades as soon as you can. These upgrades often limit programs or networks to regulate access and deal with errors in applications.
Passwords are an important part of securing your system. It is imperative that passwords consist of a combination of letters, numbers, and special characters which can either be in upper or lower case. As an administrator, you need to make sure that all the users follow such rules when making their passwords. There are tools that can assess the strength of these combinations.
Password strength is not the only thing that is important. Passwords also have to be changed regularly, and preferably, should not be reused. If new passwords are generated after a specific length of time, then it will be difficult to have continuous access if you are not the owner of the account. The users can be notified when they need to change and if the administrator specifies, will not be allowed to log in if they do not make a new one.
The root account has more access than the other accounts because it is the default account for administration. As the account associated with such privileges, attackers will often target this account. It is therefore not advisable to use the root account to lower risks. In any case, you can still login as a regular user and access files another way.
Being part of a network means that there is a constant flow of data. Without the right measures, anyone can monitor this information for his own uses. Encryption prevents third parties from accessing the data. This is the reason why it is preferable to use a password or a key for entering the network.
Take a look at intrusion detection software that are available. These kind of application will scan the system and report any suspicious activity, like port scans, that it has detected. These is essentially useful in assessing the effectivity of your security. Remember that this is only good for detection and is not for prevention.
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.
