Server : Security Operating System

Server security covers the processes and tools used to protect the valuable data and assets held on an organization’s servers. It as well as protects  the resources of the organisation. They in particular hold  very sensitive information. Cybercriminals therefore frequently target to exploit weaknesses in server security to access the information.

Common security server issues

  • Hacking of passwords
  •  running an outdated version significantly increases your risk of exposure
  • Misconfigured servers
  • Old and unnecessary accounts
  • Poor physical security
  • Patch management


Procedure of installing security system

Server security process ensure the server is well secured. The following are steps followed to ensure long-term maintenance.

  1. Record server details. First of all, identify and make a note of all the important details relating to your server, such as the identification number and the MAC address.
  2. Consider physical safeguards. Although the server is at virtual risk from adversaries, you should also consider physical safeguards to prevent unauthorized access. Restrict access to the server room to as few people as possible and ensure that keys are kept secure.
  3. Set up server logging. Keep an eye on what’s happening and enable traceability by configuring event logs. Monitor remote access logs and follow up on any suspicious activity as well as logging account logins, system configuration changes, and permission changes. Consider backing up logs to a separate log server.
  4. Avoid patching weaknesses. Check that the operating system and any other software applications are running the most up-to-date versions.
  5. Restrict software. Remove any unused or unnecessary software or operating system components. Any unnecessary services should also be disabled.
  6. Monitor hardware. Carry out regular hardware maintenance and also routinely inspect your server for any aged or damaged components that may need replacing.
  7. Ensure system integrity. Employ robust authentication methods such as two-factor authentication for all system administrators. In addition, remove any accounts that are no longer necessary.
  8. Implement backup procedures. Aim to automate regular  backups and routinely check that they are operating as expected. Additionally, remember to test recovery images from time to time.

Configuration policies

For high security proposes, ensure that your operating system is configured according to server security best practices. That is:

  • Changing the default passwords on any installed third-party software
  • Setting user privileges to the minimum necessary for the individual to do their job
  • Deleting  any unnecessary accounts
  • Creating stringent guidelines for passwords and ensuring all system passwords comply
  • Disabling any unnecessary applications.
