Unix Hardening & Maintenance

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. In Unix, Cron is used to schedule either user or system jobs, like Windows Task Scheduler. During this course, you will learn how Cron can help to automate repetitive system maintenance and administrative tasks, through the command line or the Unix shell. You will begin by observing how to configure a regularly scheduled Cron job. Next, learn how to harden your Unix system, and identify and mitigate attack methods. Other topics include how to change default passwords, close open network ports, and remove unnecessary software, services, and usernames. You will also learn how to enhance host security with Public Key Infrastructure (PKI), the PKI hierarchy, and view network packets with the tcpdump command.
