Uncover ten PDF security issues that can save you money

Are you looking for security for the purchased PDF software? If you know the ten PDF security questions listed below, you may save money in the current severe economic situation. The supplier did not tell us about the PDF products and solutions and the problems we should know.

1. carefully consider the tools used to help open PDF files. Is there a vulnerability in the tool and is it safe enough for execution?

All PDF password protection files can be deleted by the PDF password recovery software. Once the password is removed, you can perform any operations on the PDF file. Password relief or "recovery" software can be easily found on the network. There are many outstanding tools, and even those paid tools won't cost more than 10 dollars.

2. Are your PDF providers qualified for security?

Many companies claim that their products are secure. However, they do not use strong passwords or disclose their security mechanisms. In fact, most PDF providers do not have security experience and data. Many "secure" e-books on the market are just ancillary software-the software sold to different organizations as a new brand. If the supplier you are considering does not have relevant security qualifications or cannot provide adequate security protection, you should know that your documents cannot be secured.

3. Is the plug-in more secure than the execution program itself?

Because the plug-in can obtain the trust and permissions of the execution program, you may think that the plug-in is not as exposed as the execution program, at least more secure than the program itself. In fact, this is not the case.

The plug-in is an execution file, which requires the Windows administrator privilege to be installed. Therefore, the use of plug-ins to deal with computers does not have to wait until any benefit-it can only be difficult.

There will also be compatibility issues between plug-ins. The Host Program does not have any review system-it does not report plug-in conflicts and the reporting lacks interoperability. Even if the plug-ins are installed to determine whether there is a conflict between the plug-ins, it is of little significance for individuals.

Iv. zero-footprint solution (no plug-ins and download connections)

Some people claim that they can provide a zero-footprint PDF security solution (without plug-ins or downloads). In fact, this is a kind of method.

If you do not use plug-ins or independent third-party tools, the decryption key of the PDF password-protected file must be sent to the protected file, this is easily cracked by the standard PDF password relief tool. Then, the PDF editing software can delete the "protection" measures.

Apart from being easily cracked, another drawback of the zero-footprint solution is that they cannot manage print screens, print controls, virtual environments, and so on, as they do not have tools to implement these. In addition, they cannot determine whether the operation is normal, whether a plug-in of Acrobat brings potential risks, or display the time, date, and page number normally.

Companies that sell zero-footprint solutions to people often reference the Digital Millennium Copyright Act to protect your PDF files. However, they do not provide you with any real protection.

5. If you want to print a PDF file, make sure that the PDF security system can point to a real printer.

There may be multiple Print Drivers (including some print drivers provided by Microsoft) that can transmit print commands to files. If your PDF security solution cannot select a real and legal printer from it, you will certainly encounter problems.

6. If you want to talk about digital copyright management of PDF files, you must understand the situation you are facing.

This is the focus of the problem. It is not easy to crack down on intellectual property piracy, and DRM cannot completely block screen print or copy or paste. These are just the simplest methods to attack pirated files.

Do you disable these system functions for this reason? Of course, it is not necessary or impossible. You must realize that digital rights management should allow you to switch between the use of these functions, rather than being fully confined.

7. You must know that the system and service will also affect the digital copyright management.

Windows terminal servers, Citrix, and other facilities allow you to copy the entire installation on a computer. Therefore, it must be clear that digital rights management providers can control these environments, because if they cannot, you will not be able to control digital rights management.

8. Have you considered using the watermark function as a way to protect personal intellectual property rights?

Every time you sell your PDF files to new customers, your PDF security vendor does not need to provide a copy of encrypted information every time. Encrypted Files consume CPU resources, not to mention maintaining the encrypted copies of each user. Find a solution that can dynamically identify genuine users with only one encryption.

9. Do not select a method that requires you to set up complex code and encryption keys.

Any PDF security solution deserves sufficient complexity to ensure secure transmission between the customer and the author, so as to maximize the business volume. After all, the purchased solution is used. You can leave the security work to the service provider for operation. Otherwise, you will be too busy to establish these complex codes and keys.

10. Does the PDF security provider provide screen protection measures?

There are many screen image capturing tools on the Internet, such as Snagit, photo processing tools, and the Red dragonfly image capturing genie. They all support Screen capturing and saving as files, it even supports Optical Character Recognition and saving results. It should be noted that the plug-in systems follow the wishes of the Host Program because they do not control the system environment.
