This IT security checklist gives you an overview of some points to consider.

• Secure the building and the hardware
• Work in a user account by default
• Use strong passwords and change them periodically
• Define restrictive authentication rights for all users
• Run a robust, stable operating system
• Close all open ports per default / run a personal firewall in stealth mode
• All software must be up to date (use none wide spread software, replace adobe flash for example)
• Don’t forget to make the backup regularly, encrypt sensitive data
• Make regular hard disk checks (physical, logical)
• Surf with a “secure” browser (Firefox…) and use https
• Configure your Internet related programs and hardware very restrictive (browser, router…)
• Check your mails with the browser instead of a mail client software like Outlook, Thunderbird…
• Run good anti malware programs in real time mode and with automated updates
• Don’t pass sensitive information to others
• Check all (new) files on malware before saving them on your machine
• Automate the monitoring
• Check if the monitoring is working properly (disk health, log alerts, intrusion prevention system…)
• Check your system / Internet with the Kali Linux (Back Track) security tools
• Disconnect your computer sometimes from the Internet (over night…)
