PKI in Cybersecurity: What Is It, Importance, Applications, And More

Published on: 06 April 2021 Last Updated on: 27 December 2024

Cybersecurity is one of the most sought-after academic disciplines in colleges and universities. In today’s world, since there are a lot of cyber-attacks, the importance of implementing proper cybersecurity measures has become mandatory.

In this tech-driven day and age, the trend of using Public Key Infrastructure, or PKI, is on the rise. A tech person would easily understand what PKI means, but an average Joe would not know a thing about it. In this article, we are going to delve deep into knowing the basics of Public Key Infrastructure.

There are many tools like Keyfactor that provide Cyber Security certifications. So, without wasting any further time, let us take a brief look at what PKI actually is.

What Does The Term PKI Mean?

In simple words, PKI is the term that focuses on everything that establishes and runs public key encryption. Public Key Infrastructure is one of the most common types of Internet encryption that deals with Cybersecurity.

It is actually installed on all web browsers to ensure that the traffic of the website is coming from a secure place. Organizations also use PKI to secure their internal communications.

The whole concept of PKI revolves around cryptography; it ensures that proper security is provided to websites. Keep in mind that these keys are not a part of the process of encryption; they just help to authenticate the true identity of the parties or devices. They are just certificate givers.

What Are PKI Certificates?

PKI certificates are nothing but online documents that work like digital passports. They are basically given to websites or entities that want to join the PKI-secured conversation. PKI certificates are not just random authentications, as they can contain a significant amount of data.

One of the top important pieces of information that a certificate includes is the website’s or entity’s public key; the certificate is only the medium through which the key is shared.

Then comes the part of authentication. Here, the certificate comes with an attestation from a reliable source that the entity or website is who they declare to be. Let us look at some of the key elements of PKI certificates to get a better understanding.

1. Registration Authority –

The registration authority is the single most important element in the Public Key Certificate. It confirms the identities of those asking for digital certificates.

2. Certificate Authority –

The certificate authority signs the entities with its public key and issues digital certificates.

3. Certificate Policy –

This certificate policy outlines all the PKI procedures; it helps outsiders judge the authenticity of the website.

4. Certificate Database –

The Database stores the metadata and certificates until the license expires.

Now that you know the basis of PKI and PKI certificates, let us take a look at the uses of PKI.

Different Types Of Public Key Infrastructure (PKI)?

Basically, PKI (public key infrastructure) includes a system consisting of technologies, policies, and procedures. With the help of PKI, you can create, manage, and use public keys and digital certificates.

Generally, PKI falls under the basics of cybersecurity. Actually, it helps systems to secure communication and data transfer. Additionally, it also helps the system to establish user identity, services, and devices.

The following are the ways through which PKIs help you ensure cybersecurity in your organization:

1. Digital Certificates

Basically, these are electronic data structures that bind a user or any entity to their public keys. In fact, you can use digital certificates if you want to establish a secure connection between private systems and public web pages. Some examples of such systems are internal Wi-Fis, VPNs, wiki pages, etc.

2. Encryption

You need a cryptographic key if you want to authenticate devices or people. This helps in securing the network system when someone is trying to communicate with the network.

3. Digital Signatures

It will be easier to verify whether certain electronic documents are authentic or not with the help of digital signatures. Hence, when you are dealing with contracts, legal paperwork, and other records, digital signatures can help you a lot.

4. Data Protection

With a variety of features for protection, PKI helps to protect data and ensure accountability. This will help in verifying transactions.

5. Controlled Access

You can verify and establish the identity of various entities in the network. Hence, this ensures limited access to resources and network systems.

What Are The Uses Of Public Key Infrastructure?

I am sure you have heard the term SSL before; it is the most common PKI implementation. But PKI is not just limited to SSL. There are a ton of other uses of PKI as well.

Securing Local Networks.
Email Encryption.
Securing IOT Devices.
Securing Internal Communications.
Signing Documents.
Giving Recovery Key for Encrypted Hard Drives.

I hope by now you have understood the uses of PKI, so let us take a look at some of the risks that you may face if you do not execute PKI properly.

What Are The Dangers Of Poor PKI Implementation?

The thing is, having PKI does not ensure total security, but IT and Security Professionals take PKI very seriously because they are well aware of the risks. Some of the common risks that you may face due to poor PKI implementation are:

More encryption increases operational costs
Most business organizationslack the proper infrastructure to Implement PKI
Unsecured websites undermine trust.

Final Thoughts:

There you have it. Above was pretty much everything that you needed to know about PKI, aka Public Key Infrastructure. Basically, you can use PKIs to manage and control public keys. Here, your goal is to encrypt these public keys to protect the network. This ensures secure data transfer and communication on the Internet.

E-Commerce Website Security: Top 14 Must-Have Cybersecurity Features

With the rise of digitization, there has been a rise in cybercrime. In fact, when a cyberattack happens, it harms a company directly and indirectly. Also, it affects its reputation in its potential customers’ eyes. In fact, you cannot count but estimate the loss that happens. Hence, it is important to ensure e-commerce website security. In this article, you will learn about the top fourteen ways to ensure e-commerce website security. However, before that, it is also important to understand the importance of ensuring security in e-commerce websites. Hence, to learn more, read on to the end of the article. Importance Of E-Commerce Website Security In 2024, most businesses are working in the online framework. Their revenues heavily depend on their websites. If they do not emphasize their website’s security, their customer base and reputation will become vulnerable. As an eCommerce website owner, you need to comply with certain payment guidelines. These include PCI/DSS (Payment Card Industry – Data Security Standard) to ensure smooth payment transactions. Moreover, you need to install security protocols to secure your data integrity. They will not only protect your customer data from hackers but also keep the search engines satisfied. Thus, security is essential for your eCommerce website. Top 14 Ways To Ensure E-Commerce Website Security The following are some of the major cybersecurity features you must ensure on your website: 1. Implement 2-factor Authentication Does not matter how frustrating it may sound. As long as you are keeping your customer’s data secure, every security method is fine. Employing 2-factor authentication may make your customers a bit agitated. They first enter the login credentials and then enter the OTP received on their number to decrease security breaches and hacks drastically. So, employ the process and safeguard your customer accounts. 2. Get HTTPs And SSL Certification To obtain HTTPS authentication businesses need an SSL certificate to be installed on a website. Before installation, you need to buy an SSL certificate. This is because it encrypts the data communication between the server and the client. Then, it passes the data over a secure network through cryptographic functions (symmetric & asymmetric). This keeps cybercriminals from intercepting the communication. Out of all the SSL certificates, the EV SSL certificates require a user to undergo a unique validation process to verify his credibility through his name, ID, address, and more. Thus, get an EV SSL to secure your Ecommerce website and obtain the highest validation level. 3. Comply With PCI-DSS Guidelines For A Secure Payment Gateway System PCI-DSS or Payment Card Industry – Data Security Standard is a body that governs a website’s right to maintain an online payment transaction system. If you are a website that sees over six million transactions every year, you must be level 1 compliant. However, if your transactions range from 20,000 per year, you are safe as a level 4 client of PCI-DSS. The compliance helps you to secure your payment gateway system. Also, it allows you to use a third-party app to accept payments and make refunds on your behalf. 4. Use A VPN As A Night Watchman When you use public networks such as Wi-Fis to access the site, it is better to use a VPN (Virtual Private Network) to watch your back and restrict other connections to manipulate the ongoing connection between the server and the client. Without a VPN, hackers can easily manipulate the payment transaction and hack credit and debit card details. VPN will secure your customers’ payment transactions even on Wi-Fi and keep their sensitive data as safe as houses. 5. Restrict Malicious Bots Using reCAPTCHA The reCAPTCHA method is extremely effective in keeping hackers at bay. Basically, ReCAPTCHA generates random questions that a bot cannot answer. There are plenty of malicious bots lurking around the internet in hopes of finding an ideal prey for cybercriminals. When they get access to your account, malicious bots can steal information, leak it, or even bring your site down. ReCAPTCHA adds an extensive layer of security that is impenetrable for a code or a bot. It restricts bad guys’ entrance by protecting login pages, signup pages, contact form pages, form submission pages, payment gateway pages, etc. 6. Start Using A Reliable Content Management System (CMS) Choosing the right CMS is important for businesses to determine whether an eCommerce website will stay safe. Mediocre CMSs are a big risk to have. They might help you save a few bucks, but you will always be vulnerable to theft. But, CMSs like WordPress and Joomla have renounced entities having customer bases in millions. Moreover, they are regular in updating security patches and always stay a step ahead of the bad guys. The only thing you need to do is keep them updated. 7. Do Not Use Unsolicited Extensions And Plugins Plugins and extensions are necessary to enhance your website’s reach. They allow you access to multiple tools and features on the internet. However, not all plugins are safe to install. These days, due to rising cybercrimes, you must be aware of what you’re installing or adding. Cybercriminals can engrave malicious codes in the plugins, and when a user installs it, they get access to his site. Before installing any plugin, make sure that its source is known. Check for its reviews and ratings across the internet. Also, check its performance reports and badges for further inquiry and self-satisfaction. 8. Perform Audits For Site Security Site security auditing does not interest a lot of merchants, but it is essential for their survival. Site security auditing includes checking whether the anti-virus is working appropriately and whether security protocols are repelling attacks or not. As a merchant, you must initiate site auditing from time to time. It will help you prevent attacks and fix bugs and technical glitches. If detected early, some security issues can be repelled; otherwise, they may harm the website if they stay for longer periods. So, keep auditing your website at regular intervals of time. 9. Install A Firewall In Your Web Application If you own a web application, the firewall can benefit you immensely. Web Application Firewall or WAF protects the website or web app by analyzing the traffic between the application and the internet. A firewall protects the user data of the application from XSS (cross-site scripting), SQL injection, cross-site request forgery, etc. A firewall is the need of the hour to suffice the mounting cyberattacks and help sustain the business. 10. Perform Data-Backup Regularly In today’s tech world, data is more important than cash in your wallet. Here, you can earn cash again. However, once you lose data, you cannot retrieve them in the same proportion. For businesses, data is their lifeline. They thrive on data and channel their operations accordingly. Since it is immensely important, protecting it is quite a task for businesses as cybercriminals are always on the lookout for data. The best way to protect your data is by creating a copy of it and saving it on the cloud. Cloud allows you to access your data anywhere at any time, making it extremely reliable. 11. Regular Software Updates Regular software updates are crucial for e-commerce website security since they come with patches that deal with vulnerabilities. Additionally, since developers always research and improve cybersecurity, new updates let you access the latest features. In fact, they protect your website from new threats like ransomware. Also, it offers protection against data breach attempts. Moreover, software updates also let your website meet the compliance requirements of the e-commerce industry. Furthermore, it also helps in improving the overall performance of your e-commerce website. 12. Strong Password Policies Firstly, if there is a strong password policy, cyber criminals will not gain unauthorized access to the website. As a result, you can also prevent financial losses that may happen to your business. Moreover, you can also save your business from reputational damage. Generally, cybercriminals and hackers use weak passwords to penetrate networks. Thereby, they stop your business’s critical processes. Hence, with a strong password policy, you can ensure e-commerce website security. 13. Use A Secure Hosting Environment A secure hosting environment protects your e-commerce website from various security threats. These include hacking, data breaches, malware, etc. Apart from that, it also helps to maintain your site’s integrity. Also, it helps you to protect sensitive information like passwords and credit card numbers. Additionally, it also offers protection against DDoS attacks Moreover, site downtime negatively affects your search engine ranking. Here, a secure hosting environment can help you a lot. 14. Focus On User Education And Training If you invest in user education and training, you can help them respond to cybersecurity threats. Basically, your users will learn to identify and respond to threats such as phishing, social engineering, and malicious attachments. Thereby, you can reduce the likelihood of cyberattacks that can compromise your e-commerce website security. As a result, you will gain more trust from your users and customers. Final Thoughts eCommerce is booming every day. New ways of marketing, selling, and attracting are in place to make life convenient for customers. On the hind side, hackers also build new ways to capture as much data as possible. Basically, they employ bots and bugs to do the dirty work. Bots can enter your website and steal customer data, whereas bugs can get attached to plugins and gain access once you install them. Keeping track of what you are installing, where you are visiting, and who you are allowing access to is of paramount importance. However, everything can get simple if you follow these fourteen steps. This way, you can frame a robust website security system. Do you have more recommendations on how to ensure e-commerce website security?
