This is the second in a four-part series to introduce IRI CellShield. An overview is found here. The following parts demonstrate how to use the other functions in CellShield: encryption and pseudonymization. If you’re interested in finding, classifying, or masking PII in databases or flat files, check out IRI FieldShield. For semi-structured and unstructured text (log, email, .pdf, etc.) files, see IRI DarkShield.
IRI CellShield is new, seamless security software for masking PII in spreadsheets. CellShield comes as either an inexpensive Excel add-in, or in an enterprise edition for LAN-wide PII discovery, bulk remediation, and auditing. Both versions perform full or partial redaction, encryption (including format-preserving) and decryption, and pseudonymization:
Simply select the range of cells you want to protect, and then click the type of protection you need.
An easy-to-use interface guides you through the steps, and CellShield does the work for you. It also provides decryption and pseudonym restoration.
Below is a step-by-step example using CellShield’s ‘Mask Redact’ feature to mask social security numbers in an Excel spreadsheet. (Note: All information used in this example is fictional.)
1. Open the Excel spreadsheet containing the data you want CellShield to protect.
2. Select the range of cells to protect.
3. Click the CellShield tab on the Excel ribbon.
4. Select the protection option you want to use from the buttons on the CellShield menu. In this case, select ‘Mask Redact’.
5. Fill in all required information on the user form that pops up from your selection.
6. Click the button to perform the desired action (in this example, ‘Mask’), and see the results in the chosen location (either into a new spreadsheet or back within the selected range – be careful here).
