The main cybersecurity challenges in retail supply chains include: third-party vulnerabilities, which allow attacks through less secure partners; ransomware and malware, which can lock down systems or steal data; phishing and social engineering, which manipulate employees to gain access; data breaches, which expose sensitive customer information; and operational disruptions caused by attacks on critical infrastructure such as transportation and manufacturing systems. The interconnectedness of supply networks compounds these dangers, resulting in a large attack surface.

Currently, there are approximately 9 million internet retailers operating worldwide. According to some estimates, there are more than 25 million e-commerce websites worldwide. Many of these online firms also have brick-and-mortar locations with employees, cashiers with physical point-of-sale (POS) systems, and a large, geographically distributed payment network.

Cybercriminals are drawn to the retail industry because it processes and handles a vast amount of personal and financial information. The combination of physical businesses and e-commerce sites presents chances for hackers because to the mix of technology, particularly cloud-based applications.

Cybersecurity Challenges in the Retail Sector

The retail industry handles a rising amount of client data, which attracts unwanted attention from hackers and cybercriminals looking to benefit from the theft and sale of personally identifiable information (PII).

Keeping businesses operational while delivering acceptable levels of cybersecurity to protect their clients is a huge challenge. Many online and offline stores seek assistance from external security teams in developing effective cybersecurity methods to enhance network security.

Successful data breaches in retail can have serious ramifications for both corporations and their customers. The key cybersecurity risks that retail organizations must address or minimize are as follows:

Social Engineering

Social engineering is one of the most common attack vectors affecting the retail industry, particularly phishing, in which fraudsters employ various methods to mislead customers into disclosing financial information and access credentials.

Phishing attacks affect businesses of all sizes and can cause significant damage if successful. One of the risks of phishing is that a successful assault might lead to additional cyber attacks on the target organization or persons and businesses associated with the compromised data.

Ransomware

Phishing frequently leads to an attempted ransomware attack. Once a cybercriminal has gained access to a network, they can infect it with malware, such as ransomware, which encrypts a system’s data and renders it worthless without the decryption keys.

Almost 80% of the firms polled have experienced a ransomware assault, making retail the second most vulnerable industry to malware.

Near Field Communications (NFC) Payment Systems

NFC technology has streamlined payment processing by allowing retailers and customers alike by allowing merchants to accept contactless payments via smartphones or NFC-enabled cards. However, NFC payment systems entail several data security risks:

Although the NFC transmission zone is very small, it requires wireless technology, which can be vulnerable to hackers.
The system works without passwords or other access credentials.
Hackers can potentially access sensitive data stored on NFC payment terminals if they use an unsecured connection.

Software Vulnerabilities

With large, geographically distributed networks and reliance on third-party services, server misconfiguration, and software vulnerabilities are common in retail. The most common vulnerabilities include the following:

SQL injection
URL redirection to untrusted websites
Missing authentication
Missing data encryption
Infected software
Weak passwords

Automation and Botnets

Automation is ideal for retail firms since it simplifies billing, customer inquiries, email marketing campaigns, inventory management, POS systems, and checkouts. Unfortunately, thieves can also employ automation to carry out more frequent and sophisticated cyber attacks.

Botnets, for example, are networks of private, malware-infected computers managed by a single device that cybercriminals can use to attack other networks. The most prevalent botnet attacks include the following:

Credential Stuffing

A subset of a brute force attack, cybercriminals use automation software to try stolen access credentials against multiple sites. Users often re-use passwords, so stolen access credentials can unlock many user accounts for cybercriminals.

A successful account takeover can allow cybercriminals to make fraudulent purchases, steal confidential customer information, such as credit card details, or commit phishing or spearphishing attacks.

Credential Cracking

When cybercriminals do not know the usernames and/or passwords, they can use automation to guess or try random values to find valid access credentials.

Fake Accounts

One in five account registrations is a fake account. Cybercriminals use bots to create fake accounts with which to commit fraud, distribute malware, steal identities, spread false information, and engage in false communications. A competitor might use such an attack to discredit the target organization and post harmful, negative product reviews.

Web Scraping

Web scraping refers to using bots to take content and data from websites, including the HTML source code and data stored in databases. An individual can then recreate or repurpose this data.

While web scraping is not inherently illegal — it’s frequently used for collecting web information, such as market statistics, real estate listings, and weather data, for example — cybercriminals can use bots to scrape open-source intelligence or track for data leaks.

Distributed Denial of Service (DDoS) attacks

Cybercriminals can use botnets to bombard networks with requests to disrupt or disable the associated organizations. DDoS attacks can distract and divert an organization’s IT resources, making the company vulnerable to a second attack. The disruption, which can include the complete unavailability of a website, can cause a significant loss of revenue and trust.

Third-Party Risks

This refers to any risk that an organization faces from its supply chain or other external parties, such as business partners, service providers, and contractors. Many retail organizations rely on a variety of third-party vendors, such as cloud-service providers, POS system suppliers, and third-party e-commerce app developers.

There are vulnerabilities when firms transfer confidential data to third-party vendors. Furthermore, third-party suppliers may have intrinsic security vulnerabilities, such as a lack of information security regulations, encryption, or web application firewalls (WAFs).

Every third party that an organization uses enhances its attack surface. However, many organizations are ignorant of the number of third parties participating in their product or service lifecycle, and they lack the ability to conduct third-party risk assessments in order to make informed decisions regarding potential cyber threats.

Lack of Encryption

Encryption is critical for retail establishments, which handle, store, and transfer financial data every day. Without encryption, internet transmissions are clearly accessible to hackers, and a hacker might intercept messages with little effort, putting both the sender and the recipient at risk.

A man-in-the-middle (MITM) attack occurs when a hacker intercepts a signal, modifies it, and then sends it to the recipient with no knowledge of the intervention. This enables the hacker to commit fraud, such as using their own payment information to acquire funds or stealing card data for phishing or sale on the dark web.

Insider Threats

In addition to the numerous external dangers to a retail firm, it is critical to consider the possibility of insider threats. Staff and third-party contractors may utilize their closeness, insider information, and allowed access to perpetrate fraud against the companies for which they work.

Insider dangers may sometimes be inadvertent. Insiders can harm enterprises by being complacent or negligent, compromising the integrity, functionality, and confidentiality of information systems.

Internet of Things (IoT)

About 85% of enterprises use IoT devices, but less than 50% have implemented security measures to render them safe from a cybersecurity standpoint.

While integrating IoT solutions can drive efficiency by enhancing data gathering, supply chain optimization, manufacturing precision, inventory management, customer experience, delivery, and more aspects of business operations, it also poses significant threats to retail security.

IoT has a massive impact on the security posture of any retail business. Every connected device dramatically increases the organization’s attack surface.

While IoT devices come with security software, this is often woefully lacking due to low-end manufacturers attempting to keep production costs low.
Many users fail to update the default password setting with which new devices are shipped.
Users often implement IoT devices without performing required updates to ensure their software is patched.
Many IoT devices are connected to retail networks via unsecured connections.

In many cases, hackers can easily exploit the many vulnerabilities of IoT devices to breach retail security systems and gain unauthorized access to networks and their confidential information.

Retail Cybersecurity Solutions

While the retail sector attracts the attention of many hackers, and there are several access points where they can look for flaws, retailers should use best practices to improve information security and prevent cybersecurity assaults.

Cybersecurity Strategy

A well-defined cybersecurity plan is critical to improve cybersecurity for retail businesses. To define its information security policy, a company needs a Chief Information Security Officer (CISO) or someone with an analogous job.

The cybersecurity plan must be based on a rigorous risk management approach. It is feasible to build a cybersecurity plan that is appropriate for the size, sector, and goals of a retail organization by identifying and assessing the potential impact of its cyber hazards.

The CISO must represent the cybersecurity strategy and play a vital role in establishing a company cybersecurity culture. This is critical for educating and engaging retail employees enough to create a solid defense against cyberattacks.

Follow Cybersecurity Frameworks & Regulations

Many security frameworks and legislation are intended to assist specific industries in developing stronger information technology initiatives and data security practices. Some of the most significant ones that could effect the retail industry are:

General Data Protection Regulation (GDPR)

GDPR is the EU’s primary data protection law. With hundreds of pages of data protection requirements, more than a thousand fines issued, and billions of dollars taken in financial penalties, it has earned its description as “the world’s toughest privacy and security law.”

While GDPR only applies to businesses that collect or store data relating to people in the EU, achieving GDPR compliance is an excellent way to ensure a business has robust cybersecurity systems and procedures.

The regulation’s Article 5 states that the seven principles of GDPR are as follows:

Transparency, lawfulness, and fairness — data must be processed in light of these considerations;
Purpose limitation –- Data must only be collected and used for the purpose designated when collected;
Data minimization — only as much data as necessary should be collected;
Accuracy — data must be accurate and, if necessary, up to date;
Storage limitation — organizations must destroy data if it identifies data subjects as soon as it is no longer needed.
Integrity and confidentiality — personal data must be processed with adequate security measures to prevent unauthorized access and accidental damage, destruction, or loss.
Accountability — The data controller must be able to demonstrate the transparency, lawfulness, and fairness of data processing.

Payment Card Industry Data Security Standard (PCI DSS)

The PCI Security Standards Council (PCI SSC) developed PCI DSS to provide global standards and resources for safe payments.

Comprising global payment industry heavyweights, including Visa, Mastercard, Discover, and JCB, the PCI SSC’s mission to protect cardholder data is supported by its cybersecurity standards, which govern the following areas:

Secure network and system development
Cardholder data protection
Vulnerability management
Strong access control
Network monitoring and testing
Developing an information security policy

Other Cybersecurity Frameworks

The National Institute of Standards and Technology (NIST) Cybersecurity Framework and ISO 27001 are key cybersecurity frameworks retail businesses can use to develop or enhance their cybersecurity systems.

NIST is voluntary, and ISO 27001 is not mandatory for the most part, but retail businesses can use these and other cybersecurity frameworks to help reduce cybersecurity risk.

Cybersecurity Training

Retailers may prevent data breaches and other cyber problems by training their employees. This decreases the risk and potential effect of employee errors while reinforcing solid cybersecurity practices.

Training should be company-wide, beginning with new employee onboarding and continuing with frequent updates and evaluations throughout the individual’s tenure with the firm. It’s also a good idea to tailor training to different groups based on their risk exposure. Cashiers, for example, require specialized training in order to operate POS systems securely.

To help retail employees provide a robust defense against emerging cyber threats, basic training should include the following topics and best cybersecurity practices:

Understanding the company’s information security policies
Authentication protocols
Email security
Data protection regulations
The importance of keeping hardware and software up to date
Practices to maintain strong passwords
Data encryption processes
Risks of using unsecured networks, such as public Wi-Fi hotspots

Data Encryption

With hackers employing increasingly sophisticated methods to gain access to networks, encryption is critical because it makes it more difficult for thieves to intercept or change internet traffic. Coding transmissions between senders and recipients with encryption methods secures secret data, prevents interference, and allows the system to handle user identification and verification. Furthermore, ensuring secure servers and payment channels is essential.

Public key encryption, which uses digital certificates issued by trusted third parties, successfully protects e-commerce enterprises from a wide range of cyber dangers, including MITM attacks.

Internet encryption is commonly achieved using the Hypertext Transfer Protocol Secure (HTTPS) protocol, which provides security via the Secure Socket Layer (SSL) or Transport Layer Security (TLS).

Any confidential information stored on hard drives, portable or otherwise, must be encrypted to protect data.

Installing Firewalls and Antivirus

Firewalls are a fundamental network security practice that protects a retail firm by forming a barrier between the internet and the organization’s network. It monitors the border for incoming and outgoing signals, logging, flagging, and restricting activities to secure the company’s network. A firewall, when properly configured, is an effective defensive layer that aids retail enterprises in the prevention, detection, and response to cyber attacks.

Antivirus software detects and actively removes malware or viruses that may be harming devices and systems. They do ongoing scans on a device and can detect and remove malicious programs if it is mistakenly downloaded.

Access Control

Proper access management allows a retail business to limit and monitor access to confidential customer data. It effectively controls and limits who has access to critical data based on their job roles. Limiting data access can prevent unauthorized activity across the company if an employee or other user credentials are compromised.

In addition to improvement in efficiency, a primary benefit of this is that it becomes easier to identify the source of a data breach. Access control systems, which can be physical or software-based, may involve the following:

Passwords and PINS
Cards and fobs
Video surveillance
Biometric scanners

Depending on the extent of a retail business’s access control system, it can log every person entering a physical location, log everyone accessing confidential areas of the network, and insist on tougher levels of verification for those seeking to modify or transmit personal data.

Network Segmentation

Mixing transactional data with other kinds of network traffic can lead to the compromise of PII. However, separating the two through network segmentation can be challenging, especially with the following considerations:

The increased use of IoT sensors, which improves retail business efficiency but also increases attack surfaces via the increasing number of endpoints involved in daily operations;
Growing implementation of cloud-based services can also make retail businesses more efficient but also increases attack surfaces with unknown or unmanaged third-party devices and systems.

While many retailers think of segmentation and think of marketing, IT network segmentation needs to come first. The benefits of IT network segmentation include the following:

Damage control during a cyber incident because the scope of the attack can be contained within one part of the network
Improved access control, limiting access permissions to staff that need it
More efficient and effective networking monitoring and analysis
Improved endpoint device protection

Zero Trust Architecture

Zero trust network architecture aims to provide network security by requiring validation at every stage of every digital interaction. Digital transformation has revolutionized retail ecosystems, and zero trust is an excellent way to keep retail businesses secure amid an ever-evolving cyber threat landscape.

In a traditional security model, users granted access to a network may move laterally and access and extract sensitive data without further security controls. Zero trust, on the contrary, is characterized by:

Network segmentation
Strong authentication
Access control management
Granular security controls
Prevention of lateral movement

In addition to more effective security, zero trust architecture can enhance efficiency improvements and reduce the complexity of security systems.

Multi-Factor Authentication

While not infallible, multi-factor authentication (MFA) makes accounts vastly more secure than password systems alone. Even with strong passwords, the added steps of an MFA system make it more challenging for cybercriminals to gain unauthorized access to systems.

Ensuring all employees use MFA to access customer data in a retail business protects sensitive information and network integrity. In addition to a password or another kind of authentication method, MFA can include one or more of the following:

Fingerprint scan
Voice scan
Facial recognition
Retina scan
PIN code
A badge, card, or key fob
Keystroke dynamics
A one-time code delivered via a mobile app

Data Backups

Losing client information may be terrible for a retail company because it disrupts mission-critical processes such as payment processing and order fulfillment, as well as causing supply chain and inventory issues.

Worst of all, when the public discovers that the corporation has lost critical consumer data, the repercussions is sometimes severe. When possible, restoring trust following a data breach or leak might take years.

While data backups can not prevent data breaches, they can help retail businesses recover from a major cyber catastrophe. Data backups, as part of an incident response plan, make organizations more robust to cyber threats, which can have a significant impact on how soon they can resume operations, how they respond to cyber threats, and how customers perceive the brand. These are all vital considerations for retail businesses.

Regular Hardware and Software Updates

One of the reasons retail enterprises become targets for cybercriminals is their usage of various access points, which frequently combine hardware and software kinds, as well as geographically spread networks (for larger retail organizations).

The combination of having a brick-and-mortar store and maintaining an e-commerce website creates a broader attack surface and increases the likelihood of misconfiguration and other vulnerabilities.

Keeping hardware and software up to date can help preserve information security since software updates often include patches that address vulnerabilities that cybercriminals could use to gain unauthorized access to networks.

Automation

Cybercriminals are using new AI and machine learning technologies to launch more persistent and diverse attacks. As a result, the retail industry must likewise use cybersecurity automation to detect and respond to cyber threats in real time.

Machine learning technology enables cybersecurity systems to monitor typical user activity patterns and detect anomalous network activities. With adequate input data, an AI cybersecurity system may access a vast library of existing cyber threats and use this information, together with its own observations, to respond to evolving cyber attacks on the go.
