Your Guide To Protecting Personal Identifiable Information (PII)

A broad spectrum of privacy regulations governs how companies can collect, store and use Personally Identifiable Information (PII). Organizations have to make sure that they treat data confidentially and protect data in several ways. 

If data gets lost or leaked, the consequences can be very serious, resulting in hefty fines for the organization involved. This is on top of the potential harm caused to any individuals concerned by identity theft and its associated costs.

So, what's the best way to be compliant and protect PII and other sensitive data? Read on to find out.


Highlights

  • Privacy laws control how companies handle PII to keep it safe and prevent leaks.
  • Lost or leaked data can lead to big fines and harm people through identity theft.
  • Tips to keep PII safe include gathering only necessary data, assessing data sensitivity, and setting up the right safety measures.
  • To improve PII security, companies should conduct risk assessments, allow employees to see only the PII they need for their job, make rules on handling different kinds of data, and teach employees about them.
  • Another crucial step is to pick someone to ensure you follow PII rules and have a plan in case of data breaches.


What Is Personally Identifiable Information (PII)?

PII stands for personally identifiable information, which is any data that carries an individual's identity.

Here are some examples of personally identifiable information and the businesses or organizations that commonly manage it:

What Laws Protects Personally Identifiable Information?

There are several laws in place to protect PII:

  • Federal Protection: The Privacy Act of 1974 established federal privacy standards, limiting the government's use of individuals' data.
  • State-Level Rules: Different states may enforce additional rules. For example, California's Consumer Privacy Act (CCPA) gives residents more control over their personal information.
  • Health Information: If your data is about health, the Health Insurance Portability and Accountability Act (HIPAA) comes into play. It keeps medical details private.
  • Financial Data: The Gramm-Leach-Bliley Act (GLBA) regulates financial matters. This law requires financial institutions to explain their information-sharing practices to customers and safeguard sensitive data.

These laws form a network of protections that demand businesses to be responsible for how they use and manage data. 


Top Recommendations for Protecting PII

In addition to any fines after a data breach, there are costs related to investigating the issue. Customers can feel left with a lack of trust that's very tough for an organization to recover from. 

The National Institute of Standards and Technology (NIST) released a publication around 12 years ago. We now commonly refer to it as a Guide to Protecting the Confidentiality of Personally Identifiable Information

Although this report is over a decade old, its recommendations still act as a base for PII protection plans today. These are some of the key recommendations for keeping on top of the security of PII.

1. Only Collect What You Need

In most cases, an organization can only use personally identifiable information in verification processes. For instance, they can only use a person's Social Security Number (SSN) to check their identity. 

Once that part of the process has happened, a company should avoid storing the SSN. If they fail to do that, it would increase the chance of a data breach. 

NIST suggests that organizations carry out reviews from time to time. This should happen several times a year to ensure that any data saved is necessary for daily operations. 

2. Come Up With a Scale for Sensitivity and Impact Level

Organizations that collect and store data should review what kinds of PII they have. For example, they may simply collect SSNs, the addresses of individuals, or both. 

Understanding what information they keep is vital. Every kind of use of personally identifiable information, when compromised, carries with it a different risk to the individuals and companies involved.

NIST recommends assigning the categories low, moderate, and high-risk levels. An organization can determine the risk level through any previously researched list of impact factors. 

3. Put in Place Safeguards Based on Impact Levels

Not all personally identifiable information is equal. That means different types need different levels of protection that are relevant to them. For instance, a public directory lists phone numbers with the permission of individuals. This makes its protection less critical compared with other sensitive data. 

Therefore, organizations need to develop and implement an assortment of safeguards. These need to be appropriate to the different risk levels. These could include:

  • Establishing PII protection policies
  • Implementing employee training
  • Encryption during storage and transit
  • Access controls on hand-held devices if used to gain access to work networks
  • Conducting regular audits


Risk Assessments and Privilege Controls

When classifying personally identifiable information, companies should ask themselves these questions: 

  • Where does sensitive information currently live at any given point?
  • Is the current storage model of any sensitive PII insecure? 

PII risk assessments help identify and prioritize where a company's weak spots are. Here are some more key questions to ask:

  • What are the gaps in your overall security strategy? 
  • What impact do your current risks have on the sensitive documents you hold? 
  • What is the potential impact if certain files get leaked or lost?

Companies should also Implement a "least-privilege" model for any online communication access so that employees can only see the data they need to perform their work. Role-based access models allow managers to limit the assignment of access to sensitive data for greater protection.

Organizations should have a policy for destroying records securely when there is no need to keep them. This needs to be a controlled process to avoid:

  • Any accidental deletion of important data
  • The chance of traces of sensitive data left in unsecured locations

An organization's data protection policies need to include: 

  • The kinds of data you store: PII sensitive vs. non-sensitive
  • The storage and protection procedures for different types of data 
  • Ongoing training for all users about internal policies and government regulations


Appoint a PII Compliance Manager and Have a Plan

Companies should choose an employee to oversee PII compliance. This should be someone who can work across departments and see all perspectives. 

Personally identifiable information tends to move from one department to another. It's important to have excellent communication between all areas of an organization when developing a PII protection plan.

There should always be a plan of action for when a breach occurs. It's far better to prepare than to get caught without a strategy in place.


Use an Online PII Checker

Many PII plans and strategies within any organization have drawbacks. This is partly because implementing them can take up valuable time and staff effort. They're also prone to human error.

One recommendation is to use smart technology that does the job instead. iDox.ai uses smart technology that will do exactly that. It can bulk scan all types of files and documents. 

It will pull out any sensitive information that any organization can redact or dispose of. It's simple to use and cost-effective, given how many man-hours it would take to accomplish the same results.

This is going to mitigate any risk to an organization and its employees. It frees up valuable effort that an organization can better spend in other ways. Critically, it improves efficiency by allowing employees to collaborate simultaneously.
