If you are using Adobe Acrobat Pro for PDF creation, you can password-protect your documents. Adobe Acrobat Pro supports password-protection as well as enables users to apply various security parameters on PDF files. If you have no idea how to do that, you can take help of this blog post: Password Protect PDF is Easy With Adobe Acrobat Pro | N. Sem's Blog But if you don't have Adobe Acrobat Pro, then you can use a third-party PDF Protection tool. One is given in the blog post linked above. I hope the shared information would be useful for you. Thanks.
