PCI DSS#

Payment Card Industry Data Security Standard (PCI DSS) is like the rules for a club that all businesses that handle credit or debit card information must follow. It’s like making sure that your wallet is safe at a crowded market by having a good zipper and being careful—businesses need to protect card information to prevent theft or misuse.

Example: When a store takes your credit card to pay for your groceries, PCI DSS is the set of rules they follow to keep your card number and other details safe.

PCI DSS Key Requirements#

1. Install and maintain a firewall configuration#

**: Use a firewall as a barrier to keep the bad guys out, similar to a fence around your house. Example: A store sets up a firewall to prevent outsiders from accessing their internal network where they process credit card payments.

2. Do not use vendor-supplied defaults for system passwords and other security parameters#

**: Change default passwords and settings to something only you know, like not keeping the default lock code on your luggage. Example: A restaurant receives a new payment system and changes the default password to a unique one before using it.

3. Protect stored cardholder data#

**: Keep stored credit card information safe, like locking personal documents in a safe. Example: An online shop encrypts customers’ credit card numbers when storing them in their database.

4. Encrypt transmission of cardholder data across open, public networks#

**: Scramble credit card information when sending it over the internet, similar to sending a coded message. Example: A website uses HTTPS to protect customers’ data when they buy something online.

5. Use and regularly update antivirus software or programs#

**: Protect computers from viruses, just as you’d get a flu shot to prevent illness. Example: A business installs antivirus software on all its computers that handle payment processing.

6. Develop and maintain secure systems and applications#

**: Make sure your payment systems are safe and fix any problems quickly, like patching a hole in your wall. Example: When a software company discovers a bug in their payment application, they release an update to fix it.

7. Restrict access to cardholder data by business need-to-know#

**: Only let people who really need to see the card data have access, similar to a VIP list for an event. Example: A call center allows only certain employees to view full credit card numbers when necessary for their job.

8. Assign a unique ID to each person with computer access#

**: Give each person their own username and password, like a personal key to an office door. Example: Each cashier has a unique login for the point-of-sale system.

9. Restrict physical access to cardholder data#

**: Keep physical credit card information locked up, just like you would with valuable jewelry. Example: A shop keeps printed receipts with credit card information in a locked drawer.

10. Track and monitor all access to network resources and cardholder data#

**: Keep records of who comes in and out, like a video camera in a store. Example: A company uses security logs to track who accesses the payment system.

11. Regularly test security systems and processes#

**: Check your security measures often, like testing smoke detectors. Example: A retailer hires security experts to do regular checks on their network for any vulnerabilities.

12. Maintain a policy that addresses information security for employees and contractors#

**: Have clear rules for how staff should protect card data, like a handbook of dos and don’ts. Example: A business provides training to new employees on how to handle and protect customer payment information securely.

Levels of PCI DSS#

Level 1#

  • Who it applies to: Businesses processing over 6 million card transactions annually.
  • **: Big stores with lots of card sales, like a major supermarket chain.
  • Requirements: They must have an annual Report on Compliance (ROC) by a Qualified Security Assessor (QSA) or an internal auditor, and they need a quarterly network scan by an Approved Scanning Vendor (ASV).
  • Example: A national online retailer with millions of transactions must undergo a full-scale audit.

Level 2#

  • Who it applies to: Businesses processing 1 to 6 million transactions per year.
  • **: Mid-sized stores, like a popular regional grocery store.
  • Requirements: They need to complete a Self-Assessment Questionnaire (SAQ) annually and have a quarterly network scan by an ASV.
  • Example: A regional electronics chain conducts a self-assessment and submits the questionnaire to their bank.

Level 3#

  • Who it applies to: Businesses processing 20,000 to 1 million e-commerce transactions annually.
  • **: Smaller online stores, like a niche clothing website.
  • Requirements: They must also complete an SAQ annually and have a quarterly ASV scan.
  • Example: A small business selling artisanal products online fills out a self-assessment and performs the required network scans.

Level 4#

  • Who it applies to: Businesses processing fewer than 20,000 e-commerce transactions annually, or up to 1 million total transactions.
  • **: Very small merchants and businesses, like a local boutique.
  • Requirements: They are required to complete an SAQ annually and may need to undergo a quarterly ASV scan, depending on the merchant bank’s requirements.
  • Example: A single-location restaurant that processes less than 1 million transactions completes a self-assessment and scans if required by their bank.

GDPR#

General Data Protection Regulation (GDPR) is a set of laws in the European Union that gives you more control over your personal data. Imagine your personal information is a secret diary. GDPR ensures that companies ask if they can read it, use it only in ways you agree to, and keep it safe from prying eyes.

Example: If you sign up for a newsletter, GDPR requires the website to tell you exactly what they will do with your email address and allows you to say no to anything you’re not comfortable with.

Principles of GDPR#

Lawfulness, Fairness, and Transparency#

  • **: Use people’s data legally, treat it fairly, and tell them how you will use it.
  • Example: A mobile app explains in clear language that they need your location data to suggest nearby restaurants and does not use the data for anything else without telling you.

Purpose Limitation#

  • **: Only collect personal data for a specific and legitimate purpose, and don’t use it for anything else.
  • Example: A gym collects your health data to tailor a fitness program for you but doesn’t use that data to sell you health insurance.

Data Minimization#

  • **: Only gather the data that you really need.
  • Example: A clothing store asks for your size and preference in style but doesn’t ask for unnecessary details like your marital status.

Accuracy#

  • **: Make sure the personal data you keep is accurate and up-to-date.
  • Example: A bank regularly checks with you to ensure your contact details are correct in case they need to reach you.

Storage Limitation#

  • **: Don’t keep personal data for longer than needed.
  • Example: A recruitment agency deletes your CV from their database after the job vacancy has been filled and no longer needs to keep it.

Integrity and Confidentiality (Security)#

  • **: Keep personal data safe and secure.
  • Example: A clinic encrypts your medical records so that hackers cannot access them if they breach the clinic’s database.

Accountability#

  • **: The organization must take responsibility for what they do with personal data and how they comply with the other principles.
  • Example: A business that uses customer data has clear policies in place and trains its staff on data protection, so everyone knows how to handle data correctly.
  • **: The individual has given clear permission for you to process their personal data for a specific purpose.
  • Example: A newsletter website asks if you agree to receive weekly emails when you sign up.

Contract#

  • **: Processing is necessary for a contract you have with the individual, or because they have asked you to take specific steps before entering into a contract.
  • Example: An online retailer needs your address to deliver the goods you bought.
  • **: The processing is necessary for you to comply with the law (not including contractual obligations).
  • Example: A bank reports transactions to the financial authorities for anti-money laundering checks.

Vital Interests#

  • **: Processing is necessary to protect someone’s life.
  • Example: A hospital processes health data to provide emergency medical care to an unconscious patient.

Public Task#

  • **: Processing is necessary to perform a task in the public interest or for your official functions, and the task has a clear basis in law.
  • Example: A government department processes personal data to issue passports.

Legitimate Interests#

  • **: Processing is necessary for your legitimate interests or the legitimate interests of a third party unless there is a good reason to protect the individual’s personal data which overrides those legitimate interests.
  • Example: A security company monitors its premises with CCTV to prevent theft, which is a legitimate interest in protecting their property.

ISO 27001#

ISO 27001 is a global standard for managing information safely. It’s like a recipe for baking a secure cake. It tells organizations what ingredients they need (like firewalls, password policies, etc.) and the steps to take to make sure the information they hold is as secure as the cake inside a locked safe.

Example: A hospital uses ISO 27001 to ensure that all the sensitive health data they store is protected against hackers, just like a recipe that tells them how to do it step by step.

The ISO 27001 standard is a part of the ISO 27000 family of standards, which are focused on information security management systems (ISMS). Specifically, ISO 27001 provides a framework for establishing, implementing, maintaining, and continually improving an ISMS. This standard outlines the requirements for organizations to secure their information assets comprehensively.

What ISO 27001 Includes:#

  1. Risk Management Process: It requires the organization to assess the risks to its information security and to implement appropriate measures to manage or mitigate those risks.

  2. Security Controls: The standard includes a detailed set of security controls (outlined in Annex A) that organizations can implement. These controls cover various areas, such as information security policies, access control, cryptography, physical and environmental security, operations security, communications security, and compliance.

  3. Management Commitment: It emphasizes the importance of management’s involvement and commitment to the ISMS, ensuring that the necessary resources are allocated and that the ISMS is integrated into the organization’s processes.

  4. Continual Improvement: ISO 27001 requires organizations to adopt a continual improvement approach, ensuring that the ISMS is always relevant, adequate, and effective in the face of changing threats and business requirements.

  5. Documentation Requirements: The standard specifies requirements for documenting the ISMS, including policies, objectives, risk assessment reports, and records of training, monitoring, and audits.

  6. Internal Audit and Continuous Monitoring: Organizations must conduct regular internal audits to ensure compliance with the standard and continuous monitoring of the ISMS performance.

  7. Certification: While not a requirement, organizations can choose to be certified against ISO 27001 by an accredited certification body. This provides independent validation that the organization has implemented the ISMS in accordance with the standard.

ISO 27001 is applicable to all types of organizations, regardless of their size, type, or nature. It is widely recognized as a leading standard for information security management and is instrumental in helping organizations protect their information assets against security threats and vulnerabilities.

HIPAA#

Healthcare Insurance Portability and Accountability Act (HIPAA) is specific to the USA and helps keep your health information private. Think of it as a rule that tells doctors and insurance companies that they need to talk about your health behind closed doors, not in the waiting room where everyone can hear.

Example: When you visit a doctor, they might have you sign a form that’s part of HIPAA, which makes sure that your medical details aren’t shared without your permission.

What is HIPAA?#

HIPAA stands for the Health Insurance Portability and Accountability Act. It was enacted by the U.S. Congress in 1996. HIPAA’s primary aim is to protect the privacy and security of individuals’ medical information, known as Protected Health Information (PHI). It also aims to improve the efficiency and effectiveness of the healthcare system.

Key Components of HIPAA#

Protected Health Information (PHI)#

PHI includes any information in a medical record or other health information that can be used to identify an individual and that was created, used, or disclosed in the course of providing a healthcare service, such as diagnosis or treatment.

Covered Entities#

Covered entities are those who must comply with HIPAA regulations, including healthcare providers, health plans, and healthcare clearinghouses that transmit health information electronically.

Business Associates#

Business associates are persons or entities that perform certain functions or activities that involve the use or disclosure of PHI on behalf of, or provides services to, a covered entity.

Associated Rules#

  1. Privacy Rule: Establishes national standards for the protection of individuals’ medical records and other personal health information. It requires appropriate safeguards to protect the privacy of PHI, and sets limits and conditions on the uses and disclosures that may be made of such information without patient authorization.

  2. Security Rule: Specifies a series of administrative, physical, and technical safeguards for covered entities and their business associates to use to assure the confidentiality, integrity, and availability of electronic PHI (e-PHI).

  3. Breach Notification Rule: Requires covered entities and their business associates to provide notification following a breach of unsecured PHI. This rule specifies the type of information that must be included in the notification, to whom the notification must be sent, and the timing of the notification.

  4. Enforcement Rule: Outlines the procedures for investigations, imposition of penalties, and hearings for HIPAA violations.

Practical Examples#

  • If you visit a doctor and they use your health information to consult with another specialist, they are using PHI in a way that complies with HIPAA.
  • A hospital’s IT system must have security measures in place to protect patients’ electronic health records, in compliance with the Security Rule.
  • If a data breach occurs at a health insurance company and PHI is exposed, the Breach Notification Rule requires the company to notify affected individuals.

By protecting sensitive patient health information, HIPAA helps maintain individuals’ privacy and the confidentiality of their health records while also facilitating the flow of health information needed to ensure high-quality health care.

NIST#

National Institute of Standards in Technology (NIST) creates various frameworks and guidelines, including for cybersecurity. It’s like a toolbox full of different tools that organizations can use to build a strong defense against cyber threats, like burglars trying to get into your digital home.

Example: A company might use NIST guidelines to create a strong password system for its employees, so it’s harder for intruders to break in.

CIS#

Center for Internet Security (CIS) provides strategies and standards to help organizations fend off cyber threats. Imagine CIS as a personal trainer for the internet, giving tips and exercises to strengthen your online muscles against hackers.

Example: A school follows CIS guidelines to make sure that the students’ information and the school’s data are well protected against any cyber attacks, similar to following a workout routine for better security health.

Who is CIS#

CIS stands for the Center for Internet Security. It’s a non-profit organization that aims to make the connected world a safer place by developing and promoting security standards and best practices.

What is the CIS Standard#

The CIS Standard refers to the set of security benchmarks and guidelines created by CIS to help organizations improve their cyber defenses. These include the CIS Controls and CIS Benchmarks.

  • CIS Controls: A prioritized set of actions that form a defense-in-depth set of best practices to mitigate the most common attacks against systems and networks.
  • CIS Benchmarks: These are detailed configuration guides for various technology groups to safeguard systems against evolving cyber threats.

Why are CIS Standards so Important#

CIS Standards are critical because they provide universally accessible security measures that any organization can implement. They are developed by a community of IT professionals and are continually updated to address new threats. Following these standards helps organizations to:

  • Protect against known vulnerabilities.
  • Comply with regulatory frameworks.
  • Improve overall security posture.
  • Establish a baseline for their cybersecurity initiatives.

Implications for Non-Compliance#

Non-compliance with CIS standards doesn’t typically result in legal penalties as they are voluntary guidelines. However, the implications can be significant in other ways:

  • Increased risk of cyber attacks and data breaches.
  • Potential loss of customer trust if a breach occurs.
  • Greater difficulty in achieving compliance with other regulations like GDPR, HIPAA, etc., that might have legal consequences.
