In our modern digital world, data security is more important than ever. Data security protects businesses and individuals from hackers and cybercriminals who want to access sensitive information. While hacking and cybercrime are becoming more sophisticated, companies and individuals can take steps to protect themselves with Public Key Infrastructure (PKI).
What is Public Key Infrastructure (PKI)?
Public Key Infrastructure (PKI) is a system that helps to protect data security. It uses digital certificates, encryption, and authentication to protect your data. Businesses can simplify PKI with Keyfactor to protect email communications, websites, and other online services. PKI can also authenticate individuals and devices.
Public vs. Private
PKI uses a combination of public and private key encryption to secure communications. The public key is available to anyone, while the private key is only known to the owner. When data is encrypted with the public key, it can only be decrypted with the private key, making PKI an effective way to secure communications and data.
Types of Certificates
Digital certificates are like ID cards for the internet. They help to identify who you are and ensure that you are who you say you are. Certificates also help to keep your data safe by encrypting it with a unique code.
Two certificates are used in PKI: digital signatures and encryption certificates. Digital signature certificates are used to verify the identity of the sender. Encryption certificates encrypt data so that the intended recipient can only decrypt it.
Solving modern digital challenges with PKI
PKI is an essential tool for businesses and individuals in our modern digital world because it helps to protect and authenticate data, communications, and devices. Companies can simplify PKI with Keyfactor to make their security protocols more manageable.
With PKI, businesses can protect their data from hackers and cybercriminals through digital certificates and encryption.
Target Corporation was the victim of a cyberattack in late 2013. The repercussions of the attack were significant, as Target lost millions of dollars and saw its stock prices drop. In addition, the company had to spend millions of dollars on upgrading its security systems.
Secure digital communications and services
PKI can also be used to secure digital communications and services, such as email, websites, and online applications. Gmail, one of the world’s most popular email services, uses PKI to protect its users’ data. Gmail uses SSL/TLS encryption to keep data safe as it travels between servers. In addition, Gmail uses digital signatures to verify the sender’s identity and prevent spoofing.
Hack-free health care
In the healthcare industry, PKI is used to secure electronic medical records (EMRs). EMRs are confidential and contain sensitive information, such as patient medical history and health insurance information.
PKI can ensure that the devices you use are who they say they are. For example, when you connect to a Wi-Fi network, your device uses PKI to verify the network’s identity.
Protecting smart devices
PKI also authenticates devices connected to the Internet of Things (IoT). The IoT is a network of physical devices, such as cars and appliances, connected to the internet to provide assistance and information or to make them easier to use.
Secure mobile banking
PKI is also used in the financial industry to secure online banking and transactions. When you log into your bank’s website, PKI is used to verify the bank’s identity and encrypt your data. PKI is also used to authenticate mobile devices used for banking and payments.
PKI is an important tool for businesses and individuals in our modern digital world. PKI can help to protect data, communications, and devices from cyberattacks. In addition, PKI can be used to authenticate the identity of users and devices. When implemented correctly, PKI can make our digital world a safer place.
