Encryption and Access Control

Encryption and Access Control

Data encryption converts data from a readable, plaintext format into an unreadable, encoded format: ciphertext. Users and processes can only read and process encrypted data after it is decrypted. The decryption key is secret, so it must be protected against unauthorized access.

Encryption is the process of converting data into an unusable form and does not itself stop hacking or data theft. Instead, it prevents stolen content from being used, since the hacker or thief cannot see it in plaintext format.

Access control is a method of guaranteeing that users are who they say they are and that they have the appropriate access to company data.

At a high level, access control is a selective restriction of access to data. It consists of two main components: authentication and authorization, says Daniel Crowley, head of research for IBM’s X-Force Red, which focuses on data security.

FAQs

Most data is not static. Records are updated, new data is added, and files and datasets are often transmitted to and from remote locations or between users and the cloud. Encrypting data at rest—data saved on disk or other media—is essential. However, data that moves between clouds or workloads and off-site—data in motion or in transit—is also vulnerable. Therefore, encryption of the most sensitive data when in motion (transmission security) should also be considered. If large amounts of sensitive data are transmitted, it is definitely a candidate for data-in-motion encryption.

Some CSPs offer a choice—they manage the encryption keys for their cloud customers, or they allow the customer to manage them. Key management is critical—loss of keys or unsecure key management can put critical data at risk. Therefore, organizations should weigh the extra cost of CSP-managed keys versus the risk of not having direct management of these essential security controls. Full regulatory compliance may tip the scales in favor of the organization holding and managing its keys.

Regardless of who holds the keys, organizations should make certain that key access is through multi-factor identification and that key storage is itself secure and backed up in case of hardware failure. Moreover, it is recommended that organizations securely keep keys on storage separate from their data.

Access control can be applied to both physical security solutions as well as logical ones. The access control system permits only authorized personnel to enter the building or system. The system does this with a password protection system or for a physical system, a key card or fob is utilized. These fobs can be controlled remotely to be activated or deactivated.

Access control provides a range of solutions to businesses that need to control who accesses their systems. They provide added security from physical keys, although you will still be able to utilize physical keys should you need to do so. Electronic keys are virtually impossible to replicate and you won’t have to worry about losing your keys as every key is programmed with a unique code that can be replicated by the provider if lost or stolen. Your old key will then be deactivated and rendered useless.

Another benefit of access control systems is that you’ll be able to set days and times that each user is able to access the building and even customize locations that your employees can access. Access control makes security easy and customizable for everyone that needs to be on site.

You’ll also be able to record who accessed your building and when. All of this data is recorded and you’ll be able to access it at any time. This data is particularly useful for times when security breaches, theft, or other suspicious activity occurs.
