For modern web professionals, building a great website is only half the battle — the other critical half is securing it. Cybersecurity is not a one-size-fits-all strategy because different industries have unique and often legally mandated standards. Every designer, developer and business owner must understand these industry-specific standards to protect their clients and their businesses.
This guide walks you through the different cybersecurity rules governing e-commerce and finance, health care, education and general data privacy, so you can build sites with confidence.
E-commerce and Finance — Complying With PCI DSS
The Payment Card Industry Data Security Standard (PCI DSS) is a global rulebook created by the Payment Card Industry Security Standards Council to protect payment data from the moment it is captured through transmission and storage. It applies to any business that accepts or transmits credit card information.
Protecting this data is a top priority. According to a PwC report, 78% of organizations expect their cyber budget to increase over the next 12 months, as businesses continue to face a widening array of cyber risks. Investment in artificial intelligence was identified as the top priority, followed by cloud security, network security and data protection. This points to greater scrutiny, more tools and higher expectations on anyone building checkout experiences.
For web professionals, the golden rule is never to store card data. Storing credit card numbers, expiration dates or CVV codes on the server creates a massive and unnecessary liability. While the client is responsible for compliance, the design and development choices directly affect their ability to follow standards.
The most effective way to handle this is to offload risk by integrating PCI-compliant gateways that handle sensitive fields in their own secure environment. On the developer’s side, a hardened network and application stack must be maintained. The standard expects strong passwords, patched software and no vendor-supplied defaults on any device or app that could touch the card data environment. These basics are directly addressed by the Council and remain among the leading causes of breaches among small merchants.
Health Care — Adhering to HIPAA
The Health Insurance Portability and Accountability Act (HIPAA) sets national rules for protecting health information. The Privacy Rule limits when protected health information can be used or disclosed, while the Security Rule requires administrative, physical and technical safeguards for electronic protected health information (PHI).
The health care industry has been a frequent target for attackers, and the fallout can include exposed records, regulatory penalties, class action lawsuits and lasting loss of patient trust. High-profile incidents from recent years at major insurers and hospital systems have shown how a single compromised portal or third-party tool can compromise millions of records and disrupt care operations.
The cases of Anthem, Excellus, Premera and the UCLA Health System in 2015 alone exposed millions of patient records. These cases highlighted that overlooked systems, such as printers and portals, can be the weak link that triggers heavy regulatory and financial fallout. Anthem, for example, found its database of potentially up to 80 million people exposed after its administrator’s credentials were hacked. In the same year, up to 11 million client records under Premera Blue Cross were compromised.
The Meaningful Use program is designed to reward organizations for improving quality, safety and patient privacy by digitizing health records. Yet within most health care institutions, it is typical that 25%-35% of patient data is in analog format. This creates a need for IT to secure the flow of information and transfer physical documents into the digital world.
As a web professional, your projects should encrypt data in transit and at rest on servers that host any PHI. Use secure forms that never send protected details through standard email, and choose hosting and key vendors willing to sign a Business Associate Agreement, since they become part of the compliance chain. Enforce role-based access so only authorized users can see protected data, and document a risk analysis process that you can repeat with each major feature release.
Education — Understanding FERPA
The education industry is governed by the Family Educational Rights and Privacy Act (FERPA). This law protects student record privacy, including grades, class schedules, disciplinary records and other personally identifiable information. It applies to all schools that receive funds from the U.S. Department of Education, as well as to third parties acting on their behalf.
If you are building for an educational institution, design with those rights in mind. Student portals must require individual, secure logins. Do not publish grades or schedules on public pages, and use role-based access so students, parents and staff see only what their role allows. The Department of Education’s student privacy program provides guidance for edtech vendors, which you can use as a checklist during procurement and integration.
A practical pattern is to centralize authentication and authorization, then pass only the minimum data needed for each tool. Maintain an inventory of vendors that receive student information and map the fields you send to prevent accidental data sharing.
General Data Privacy — Navigating GDPR and CCPA
Beyond specific industries, general data privacy laws have a huge impact on web development. The two most prominent are the General Data Protection Regulation (GDPR) in the European Union and the California Consumer Privacy Act (CCPA). These laws are not industry-specific. They are location-based and focus on giving individuals rights over their personal data. If you work with visitors from these regions, your site must respect these frameworks.
For day-to-day builds, this means three things:
- Writing privacy policies in clear language, explaining what you collect and why
- Presenting consent controls for cookies that process personal data, with an option to reject on the first layer and no pre-checked boxes
- Preparing for user data requests by incorporating the export and deletion processes into your operational workflow
GDPR and CCPA require fundamental changes to how a site is built and managed, so focus on structured development from the outset. You can standardize privacy features across projects, such as preference centers, consent banners and data request forms by using well-documented, reusable parts. You can save money and stay compliant by designing versatile and easy-to-understand modules. This way, you do not have to write the same logic and behavior stays consistent across sites.
Building Trust Through Security
Security is part of your job. Knowing the different industry-specific security rules is not only important to avoid sanctions, but also to build trust, keep users safe and establish a reputation for quality and safety. Be a proactive collaborator with your clients as they work on their security.
