Developing Web applications over Linux surely renders a great deal of benefits to Web developers, when it comes to the attributes ofspending less time worrying about security issues and working with an open source software. Nevertheless, hackers do try to scan general Web applications for vulnerabilities. Let’s explore how you can do away with these kinds of security threats efficiently.
- Keep Linux software up-to-date
Implementing security patches is a crucial part of maintaining Linux server. Apparently, Linux offers all indispensable tools to keep your system well-run, and also enables seamless upgrades among versions. You should review and apply all security updates at the earliest. And, you can utilize the RPM package manager, for instance yum, dpkg, or apt-get in order to apply thesecurity updates.
- Maintain asturdy password strategy
Utilize usermod/ useradd commands for creating and maintaining user accounts. Ensure to have a sound password strategy. For instance, a strong password comprises at least 8 characters with a combination of alphabets, special characters, numbers, and upper & lower alphabets. In addition, ensure to pick a password that you can remember easily.
- Physical server security
You require protecting Linux servers physical console access by configuring the BIOS and disabling the booting from CDs, DVDs, and USB pens. In addition, you need to set BIOS and carry out boot loader password for safeguarding these settings. All persons are required to pass certain security checks before accessing the server and all production boxes are required to be locked in Internet Data.
- Disable IPv6
IPv6 or Internet Protocol version 6 renders a fresh internet layer that substitutes IPv4 or Internet Protocol version 4 in the TCP/IP protocol suite. At present, there are hardly any tools that are capable of checking a network system for IPv6 security settings. Crackers can use IPv6 to transmitwrong traffic as most admins are seldom monitoring it. Thus, you should disable IPv6 unless it is required by network configuration.
- Utilize intrusion detection system
An intrusion detection system is the one that is capable of detecting malicious activities, such as denial of port scans, service attacks, or even effortsto crack into computers by checking network traffic. It is generally suggested to deploy a reliability checking software before system gets online in a production environment.
- Utilize a centralizedauthentication service
If there is no centralized authentication system, there are good chances of the user’s authentication data becoming inconsistent that might lead to outdated identifications and forgotten accounts. A centralized authentication service enables you to maintain central control over Linux account and authentication data.Moreover, you are able to synchronize authentication data among servers.
- Protect directories, files, and emails
Linux provides top notch protections against unapproved data access. Nonetheless, authorizationsset by Linux become irrelevant, in case an attacker gains in-person access to a computer and shifts the hard drive of the computer to another computer for copying and analyzing the crucial data. Thus, you need to protect files and partitions by means of encryption, decryption, and passwords.
