Manufacturing Business Security: How To Protect Your Manufacturing Business From Cybersecurity Threats?

On September 22, 2021

Manufacturing businesses across the world were able to operate without strengthening their cyber security posture as that sector initially did not face critical cyber threats. However, the advent of PLC-SCADA (Programmable Logic Controller – Supervisory Control and Data Acquisition), IoT (Internet of Things), Robotic Automation, M2M (Machine-to-Machine) Communication, and State-of-the-Art Technological innovations have attracted the heat from APT (Advanced Persistent Threat) groups. Disrupting production and assembly lines, intellectual property theft, economic and employment failures, and hacktivism are some of the causes and motives that drive attackers apart from just the financial gains.

5 Best practices businesses can follow to protect manufacturing, production and assembly lines from hackers:

Educate and train the employees, partners, and customers: Humans are the weakest link in the entire IT infrastructure that is evident when attackers phish employees for credentials. Security awareness training must be conducted periodically and the company can release advisories and suggest best practices as well. People must be trained to identify, block and report phishing and malicious emails which often is the simplest yet effective way to ward off the biggest cyber threats. Employees must be able to differentiate between genuine and spoofed email senders and user profiles on social media based on a list of red flags provided to them. Everyone in the organizational ecosystem must take ownership of cybersecurity from the entry-level work roles to the C-Suite.
Deploy 2FA / MFA with Biometrics: Implementing 2FA (2-Factor Authentication) and MFA (Multi-Factor Authentication) along with biometric locks will keep unauthorized users or hackers at bay. It is advised to periodically change the credentials used to access the various digital resources across your organization. Modify and update the vendor-supplied default security configuration to customize as per the business requirements. Deploying an appropriate IAM (Identity and Access Management) plan not only prevents an accidental information modification from employees unauthorized to do so but also limits the scope of access for hackers having stolen the employees’ credentials.
Update and upgrade the software and hardware: Always update the hardware and software components used in your equipment and technologies periodically as per the vendor’s suggestions. Your lethargy or temptation to ignore the security updates might attract the attention of attackers to hack into your production systems and cause damage. Customers, partners, and end-users must be notified every time a new hardware or software update or upgrade is available for roll-out with the company. Patch the software for existing vulnerabilities and also design plans for setting up network communication architecture implementing defense-in-depth and depth-in-defense approaches.
Data Privacy & Security with Disaster Resiliency: Companies must be aware of all the T&Cs (Terms and Conditions) about data storage and usage policies of its partners and customers. It is advised to conduct KYC (Know Your Client) background checks before storing any PII (Personally Identifiable Information) or confidential data of your customers and partners. You must encrypt the trade secrets, blueprints, business strategy related files in online and/or offline storage. Utilize encrypted and secure channels to share or transfer data with authorized users and groups. Businesses must aim to procure and deploy a robust and reliable technology tech-stack. The SaaS (Software-as-a-Service), PaaS (Platform-as-a-Service) and IaaS (Infrastructure-as-a-Service) applications must be used along with leveraging Military-grade encryption, Fail-safe Data Backups, Anti-Ransomware Solutions and Disaster Recovery mechanisms to protect your data from loss or corruption in case of any human or natural disaster.
Holistic IT Strategies: Maintaining your organization’s credibility in the market among customers via complying to the various regulatory compliances is very important to protect highly sensitive business information. In-house SOC (Security Operations Center) team can monitor the real-time activities of Users, Services, and Applications in your productions and assembly environment. Alternatively, to facilitate inadequate budgets and lack of resources, you can hire an MSSP (Managed Security Service Provider) to outsource your security logging & monitoring requirements. They help in preventing, detecting, analyzing, & mitigating security risks, threats, vulnerabilities, and incidents. Protect the industrial automation machinery & M2M communication equipments with various security solutions such as NGAVs (Next-Gen Anti-Virus), DLP (Data Loss Prevention), XDR (Extended Detection and Response), Honeypot and likewise. Securing the productions and assembly lines would give Hackers a hard time targeting your manufacturing business.

As cyber attacks are becoming more evolved and complex, it has become critical for organizations to possess basic cyber security controls. In order to ensure the safety of business’ confidential data, organizations need to enforce appropriate security controls.

Here are some cyber security controls that every business needs to know:

Automated Patching: Patches are introduced by tech developers in order to fix critical vulnerabilities found in a network, app, or system. Timely fixes or patching is essential to prevent the spread of security breaches via open vulnerabilities which may cause extensive damage to a business. Automating the updates can save time and resources spent by IT professionals for manually searching devices to evaluate and install latest updates. Automation allows simultaneous implementation of patches for several vulnerabilities.
Full Disk Encryption: A great way to strengthen the security health of an organization is to allow Full Disk Encryption (FDE) data on hard disks in an organization. Enabling cyber security controls that store user credentials securely and drive data confidentiality helps in ensuring safety of business data from cyber criminals. In addition to FDE, make sure to backup the data regularly to tackle situations such as disk crash. Also, make sure to store passwords and encryption keys at separate location as no one can access a system without appropriate credentials.
Screen Lock: The next cyber security control to be implemented is automatic screen lock. Once this control is activated, a machine enters sleep mode after being idle for a set time and user has to enter password when returning to the machine. This prevents any one from accessing a machine when unattended. This cyber security control becomes even more important for users working from remote locations.
Enabling Firewall: It may seem like a basic strategy but it is highly important to activate firewall across all company devices. A firewall is a software that tracks inbound and outbound activities from a network and blocks the traffic that seem unsafe for the network based on a set of security rules. This prevents unauthorized applications from reaching endpoints and penetrating into the network. This helps businesses in mitigating risks and overcoming new cyber challenges.

When surfing online, a common pop-up that a user receives is ‘Accept The Cookies’. Some websites use cookies to provide a more personalized and convenient website browsing experience. But in order to understand the relationship between cookies and user’s online privacy, it is first important to understand what cookies are.

What Are Cookies?

Cookies are text files that contain small amounts of data that can be used to identify your computer network. Specific HTTP cookies are used to identify specific users for improving their web browsing experience.

Data stored in the cookies is created when a user connects to an online server. This data is marked with an ID that is unique to the user and his computer/system. When cookies are exchanged between user’s computer and network server, the server reads this data for identifying the information that should be served to the user.

Cookies are of two types:

Magic Cookies: This is an old computing term that refers to packets of information that can be sent & received without any charges. This data is commonly used for logging in to a computer’s database systems. This concept is a precursor of modern day ‘cookies’.
HTTP Cookies: It is a repurposed version of magic cookies, which was created for internet browsing. It was specifically created to assist web browsers in tracking, personalizing, and saving information about a user’s online session. The server sends cookies only when it wants the web browser to save it. These are stored locally by the browser, so that when the user revisits a website, web browser can return the data stored in the cookies to help the server recall data from previous session. HTTP cookies can be further classified as – Session Cookies and Persistent Cookies.

How Are Cookies Used?

While session cookies are only used during navigating a website and are stored on RAM (never written to the hard drive), persistent cookies remain on the computer indefinitely.

Persistent cookies can be used for two main purposes:

Authentication: They help in identifying if a user has logged in and if yes, under what username. They also help in streamlining login credentials so that the user is not required to remember them.
Tracking: This is to track multiple visits to a website or webpage over time. This property is used by merchants to identify a user’s browsing behavior to suggest products that may interest the user.

Why Cookies Can Be A Threat?

Since the data written in the cookies cannot be changed, they are harmless. However, cyber criminals can get hold of the cookies to access victim’s browser sessions.
Third-party cookies (generated by ads on a webpage, even if user doesn’t click on ads) allow the ad owners to track user’s browsing history, thus interfering in his privacy.
Zombie cookies can be permanently installed on user’s system and reappear even after deleted.

Removing cookies can help in combating the risk of privacy breach.

As the ‘Work From Home’ and ‘Bring Your Own Device’ culture has gained popularity, organizations have increased their attention towards mobile security. Most employees routinely access organizational data from their personal mobile devices, cyber criminals also try to gain on this opportunity. So, organizations have to keep their employees informed about major cyber security concerns that can be woven around smartphones.

Here are some major cyber security concerns of smartphone users:

Data Leakage: Data leakage refers to unauthorized transfer of data from within an organization’s systems to an external destination or recipient. It is one of the most bothersome cyber security threats for enterprises. In order to combat the issue of data leakage, organizations need to implement an app vetting process that does not overwhelm the administrator and does not frustrate the users as well. However, this doesn’t help in taking care of data leakage resulting from user error such as transferring company files onto public cloud, copying confidential information to a wrong place, forwarding an email to unintended recipient, etc.
Social Engineering: It is a manipulation technique that exploits user error to gain private information, unauthorized access, etc. These scams are also known as ‘human hacking’ scams because these scams work by luring unsuspecting users into exposing data, spreading malware infections, or giving access to restricted systems. Social engineering scams usually aim at theft of information as well as sabotaging organization’s reputation by disrupting or corrupting data. Common examples of social engineering attacks include phishing attacks, baiting attacks, physical breach, pre-texting attacks, access tail-gaiting attacks, quid pro quo attacks, scareware attacks, etc.
Wi-Fi Interference: A mobile device is secure only in case the network through which data is transmitted is secure. Cyber criminals find an array of ways to intercept the transmission. Some of the tactics include setting up fake Wi-Fi networks, intercepting communications transferred across public networks, etc. Organizations can combat this issue by motivating users to download and make use of VPN.
Cryptojacking Attacks: Cryptojacking is a type of attack where cyber criminals use victim’s device for mining cryptocurrency without victim’s knowledge. The cryptomining process relies on the user’s resources such as mobile device processor, network, data, storage, etc. This reduces the performance level of the mobile device.
