chmod
How to explain.
Alright chomd is alittle more in depth then this but this should be good for your needs.
Think for this instance of three columns.
owner group and others
each column is represented by sum of numbers 1 2 and 4
1 executable permission
2 write permission
4 read permission
so say we wanted to give only the onwer read write and exec. ability whe would type chmod 700 `filename or dir`
where the first column is onwer and 4 + 2 + 1 equals 7
the second column is group and the third is other or world
so if you what only the owner to read write and exec but anyone in the group to read and exec as well as anyone else to be able to just read and exec you would type chmod 755 `filename`
For what you stated you will probably want to chod 755 the directories that you altered.
I hope this helps
