I agree with the replies.
It is too simple to make a sweeping generalization "open source is more secure" or "open source is less secure".
So, anyone who believes either statement, yes or no, is both right and wrong, because the statement is too general and therefore meaningless
Even the term "security" has no real meaning. In discussing IT security you must discuss risk, and to discuss risk you must think in terms of vulnerability, threat and impact.
For example, an open source system turned on and sitting in your closet without a connection to the Internet may be more secure that the most expensive closed source system on the Internet
In other words, there are security experts born every minute, it seems, and very few understand what they are actually taking about. If you understood security and risk management, you could not answer such a simple question as "is open source more or less secure?" because this question has no context and just lends to endless, meaningless debates by people who do not understand the nature of IT security and risk management.

securetty_types(5) SELinux configuration securetty_types(5) NAME
securetty_types - The SELinux secure tty type configuration file DESCRIPTION
The securetty_types file contains a list of types associated to secure tty type that are defined in the policy for use by SELinux-aware applications. selinux_securetty_types_path(3) will return the active policy path to this file. The default securetty types file is: /etc/selinux/{SELINUXTYPE}/contexts/securetty_types Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)). selinux_check_securetty_context(3) reads this file to determine if a context is for a secure tty defined in the active policy. SELinux-aware applications such as newrole(1) use this information to check the status of a tty. FILE FORMAT
Each line in the file consists of the following entry: type One or more type entries that are defined in the policy for secure tty devices. EXAMPLE
# ./contexts/securetty_types sysadm_tty_device_t user_tty_device_t staff_tty_device_t SEE ALSO
