Sun Solaris Server administration includes the management of the client/server relationship, network management, errors management, resources sharing on the NFS server and client, adding users, setting up partitions, domains and name server configurations, disk management and using the certain administrative tools to configure, maintain and troubleshoot the network.
Command line interface is one of the best options for performing the administrative tasks for the Sun Solaris operating system. By using the administrative commands, you can perform any kind of task. The two major security threats to the Solaris operating systems are the unauthorized access from the local area network and the intruders and hacker’s attack from the internet. To protect your Solaris operating system from the internet and external threats and the other vulnerabilities, you need to implement the following security techniques.
- Install the Latest Patches
Install the latest security patches of the Solaris operating system, which are required to deal with the security bugs at the real time. You can download the latest security patches by using this Perl script “patchk”
- Stop Unnecessary Services
In most of the case certain SUN OS services are not required. Evaluate your system requirements and you need to identify and stop these services. Also you need to identify and stop the unused network services.
To prevent the buffer overflow that leads to the execution of the certain malicious codes on your machine, you need to following lines in the /etc/system file.
In some cases, hackers change some files to gain control as a super administrator. With pkgchk command, you can check if the following files have been changed.
If you notice errors, while accessing these files, this means that your system has been compromised. The best possible solution to deal with this problem is to do a fresh installation of your Solaris OS.
