How does a backup database work?
Typically, the process involves creating a backup copy of a database in production, loading it to a separate environment, eliminating any unnecessary data, and then masking data while it is in stasis. The masked copy can then be pushed to the target location.
What happens when data is encrypted?
When data is encrypted, it becomes use less unless the viewer has the decryption key. Essentially, data is masked by the encryption algorithm. This is the most secure form of data masking but is also complex to implement because it requires a technology to perform ongoing data encryption, and mechanisms to manage and share encryption keys
What is data masking best practice?
A data masking best practice, which is explicitly required by some regulations, is to ensure separation of duties.
What is the goal of data masking?
The goal is to protect sensitive data, while providing a functional alternative when real data is not needed —for example, in user training, sales demos, or software testing. Data masking processes change the values of the data while using the same format. The goal is to create a version that cannot be deciphered or reverse engineered.
What is pseudonymization in data protection?
According to the EU General Data Protection Regulation (GDPR), a new term has been introduced to cover processes like data masking, encryption, and hashing to protect personal data: pseudonymization.
What are the layers of security?
Our comprehensive approach relies on multiple layers of protection, including: 1 Database firewall —blocks SQL injection and other threats, while evaluating for known vulnerabilities. 2 User rights management —monitors data access and activities of privileged users to identify excessive, inappropriate, and unused privileges. 3 Data loss prevention (DLP) —inspects data in motion, at rest on servers, in cloud storage, or on endpoint devices. 4 User behavior analytics —establishes baselines of data access behavior, uses machine learning to detect and alert on abnormal and potentially risky activity. 5 Data discovery and classification —reveals the location, volume, and context of data on-premises and in the cloud. 6 Database activity monitoring —monitors relational databases, data warehouses, big data, and mainframes to generate real-time alerts on policy violations. 7 Alert prioritization —Imperva uses AI and machine learning technology to look across the stream of security events and prioritize the ones that matter most.
What is data masking?
Data masking is a data security technique in which a dataset is copied but with sensitive data obfuscated. This benign replica is then used instead of the authentic data for testing or training purposes.
Why is data masking important?
Data masking is essential in many regulated industries where personally identifiable information must be protected from overexposure. By masking data, the organization can expose the data as needed to test teams or database administrators without compromising the data or getting out of compliance.
Why Do Organizations Need Data Masking?
In recent years, data security regulations have become very strict. The introduction of regulations like the General Data Protection Regulation (GDPR) has forced organizations to protect their data fiercely. This has put a significant restriction on the usage of the organization’s data for testing or analysis.
What Are the Common Data Masking Methods?
In the substitution method, the original data value in a data record is replaced with an inauthentic value. For example, in a customer database, every male name might be replaced with a standard value. Every female name might be replaced with another value.
What Are the General Rules of Data Masking?
Data masking techniques need to follow a few rules so that the transformed data remains useful.
Data Masking Workflow Options
In static data masking workflow, a copy of the original data is made, and masking is applied to this copy. There are two popular static data masking methods.
What Are the Challenges of Data Masking?
While the process of masking seems simple, a data masking system faces many challenges in making a meaningful, masked copy of production data.
What Are the Benefits of Data Masking?
Data masking is an effective solution for various data security threats like data leaks, hacking, insecure data interfaces, or intentional data misuse.
What are some examples of obfuscation methods?
Examples of statistical data obfuscation methods include differential privacy and the DataSifter method .
What is data obfuscation?
Accordingly, data obfuscation or masking of a data-set applies in such a manner as to ensure that identity and sensitive data records are protected - not just the individual data elements in discrete fields and tables.
What is masking used for?
It is more common to have masking applied to data that is represented outside of a corporate production system. In other words, where data is needed for the purpose of application development, building program extensions and conducting various test cycles.
What is shuffling in data obfuscation?
The shuffling method is a very common form of data obfuscation. It is similar to the substitution method but it derives the substitution set from the same column of data that is being masked. In very simple terms, the data is randomly shuffled within the column. However, if used in isolation, anyone with any knowledge of the original data can then apply a "What If" scenario to the data set and then piece back together a real identity. The shuffling method is also open to being reversed if the shuffling algorithm can be deciphered.
What is static data masking?
Static Data Masking is usually performed on the golden copy of the database, but can also be applied to values in other sources, including files. In DB environments, production DBAs will typically load table backups to a separate environment, reduce the dataset to a subset that holds the data necessary for a particular round of testing (a technique called "subsetting"), apply data masking rules while data is in stasis, apply necessary code changes from source control, and/or and push data to desired environment.
Why do we mask data?
Data masking or data obfuscation is the process of hiding original data with modified content (characters or other data.) The main reason for applying masking to a data field is to protect data that is classified as personally identifiable information, sensitive personal data, or commercially sensitive data. However, the data must remain usable ...
What is character scrambling?
Character scrambling or masking out of certain fields is also another simplistic yet very effective method of preventing sensitive information to be viewed. It is really an extension of the previous method of nulling out, but there is a greater emphasis on keeping the data real and not fully masked all together.
