Whether you save data at rest on physical storage devices, a private or public cloud, or 3rd party storage platform, security is needed in one or another manner. The post is going to aware readers with what exactly is ‘data at rest’ in cloud computing. After this, we are going to illustrate effective measures for protecting data at rest.
An Introduction on Data At Rest
Data at rest is referred to the amount of content, stored in computer storage devices. It excludes the information that is transmitting over the network or is temporarily residing in system memory either for reading or updating purpose. Archival or reference documents, which are rarely or never modified are considered under ‘data at rest’. It also involves the information, which is subjected on regular basis without any constant modifications.
Data at rest is not actively moving from one device / network to another device / network. Information is stored on laptop, flash drive, hard drive, or on any other portable or importable devices. The purpose of data at rest is to protect inactive information, which is archived on any component or network. Sometimes it is considered less vulnerable in comparison to the data in transmit mode. It is easy for attackers to target on data, which is stored on storage components. Well, the risk level is based upon the security approaches, which are applied for securing information in either state. Protecting data at rest is vital operation for today’s enterprises because hackers are discovering innovative methods to perform sudden data breach or Cyberattacks.
Enterprises, government agencies, and other companies of different domain, are having a serious concern regarding threats performed by hackers on the data at rest mode. Cloud security measures are needed to keep data at rest safe from stolen, accessed, or modified by unauthorized people.
Effective Ideas For Protecting Data At Rest
In a Data Breach Statistics 2017, it was found that enterprises were keeping their confidential information opened on public cloud. People have to understand that leaving data at rest free for attackers to attack will surely lead to Cybercrime. Tons of advanced security measures need to be adapted to robust information protection on the device where content is stored. The most effective and useful solution to secure data at rest is ‘cloud data encryption’. No matter whether your content is stored on public, private, or hybrid cloud, you should store data in an encrypted manner. Apart from this, the following four are common online data protection solutions that can be adopted by enterprises to be safe from Cyberattacks:
- Distributed Programming Framework Security – A user authentication procedure needs to be established in order to achieve trust at an initial level. Administrator needs to ensure security properties of every teammate, make use of role-based access controls and authorize file accessing through predefined security policies. Apply strong protection measures to secure PII i.e., personal identifiable information. This prevents data subject identity, which is linked with external content. For this, high-level encryption standards can be used to avoid attacks from external threats.
- Data Storage and Transaction Logs Security – A bundle of measures, which comprises of exchange of signed messages implementation, should be digested to track potential disputes. Enterprises should check that data at rest is stored securely on public clouds or untrusted servers. Continuous improvement in scalability with wide encryption, key rotation, and lazy revocation is required. Companies can also go for unbreakable security by implementing proof of retrievability in cloud computing.
- Use Best Input Filtering Options in BYOD Models – This another point for protecting data at rest recommends users to create model, which represents normal behavior and detects deviations or outliers from the normal input. Companies need to perform this along with the use of traditional endpoint security to filter, detect, and block malicious input. This idea will limit down the total amount of extra computation, required for resource-constrained endpoint devices.
- Adopt Cryptography Techniques to Secure Core Data – Sensitive content in a business are the one, which can put business’s reputation at risk on its leakage. Whether this vital enterprise data is at rest mode or in transmit mode, a secure cloud storage programming is needed. Cryptography technique should be implemented for big data protection. It is the method of storing data securely at rest and enable only the authorized person to read and use it.
CloudCodes – One of the Best Data At Rest Security Solutions
Proper encryption system and key management procedure is an important factor to ensure sensitive content data protection. Also, organizations are having responsibility of maintaining ongoing security standards and compliance with regular updates. Till now, only CloudCodes is the one that actually offers granular encryption and role-based access control for sanctioned and unsanctioned applications. Bundle of methods for tokenization and encryption is offered by this all-in-one solution for protecting data at rest. CloudCodes serves at its best in rendering online data protection to its business’s client content throughout the process. Enterprises can give it a try and go for one that suits their business in best manner.
