I am trying to protect about 25 files. excel documents, pdfs, word, .tiffs to name a few.<br />
<br />
I need these files to be able to be accessed and used, but what I dont want to happen is the following.<br />
<br />
Delete the files<br />
Rename the files<br />
Copy the files<br />
Email the files out<br />
Prevent them from being moved to removable media<br />
<br />
Anythingthing else that I cant think of. Most people just need to be able to open them and view the data but not change the data. <br />
<br />
I've read about DLP solutions but they are network wide and I wanted to narrow it down to 25 files being protected and no tthe whole network. I just simply need to protect them from within.<br />
<br />
Any Ideas?

Protecting Files from Internal threats

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.

Vulnerabilities

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Encryption

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
