So, unfortunately, I’m not actually going to cover how to keep a fantastic WordPress site secure.Īs usual with any security advice, it’s good to have some common sense when reading it. All of these ideas are familiar from Linux desktop & server environments, but I’m going to show you how to apply them to Yocto builds in practice.
In this new blog series, I try to explain how to make your Yocto systems more secure by adding some common-sense security to the system.

Or perhaps you’ve just been postponing that security update on your Android phone for six months. Or perhaps you forgot to update your WordPress plugins, and now your fantastic development blog is hacked.

Let’s assume we want to create a user with name ‘sysadm’, run following useradd command # useradd -G wheel sysadmĪssign the password to above newly created user with beneath passwd command, # echo | passwd sysadm -stdin While creating a new regular user, specify ‘wheel’ as secondary group. Login to your system as root user or if you have logged-in as regular user switch to root user, use following command $ su - root 2) Create regular user with useradd command
