As businesses increasingly rely on technology for their operations, cybersecurity has become a top priority. Cyber attacks can cause significant damage to a company’s reputation and finances. Many businesses have implemented various security measures to protect their systems from cyber threats. However, one security measure that is gaining popularity is the implementation of 802.1x for cybersecurity. In this article, we will explore why your business needs to implement 802.1x for cybersecurity.
What is 802.1x?
802.1x is a security standard that is used to authenticate and authorize devices that connect to a network. The protocol requires clients to provide valid login credentials before access to the network is granted. This mechanism is often used in wireless networks, which makes it impossible for an attacker to connect to the network without valid credentials.
How does 802.1x work?
802.1x works by using three components: a supplicant, an authenticator, and a server. The supplicant is the device that wants to authenticate to the network. The authenticator is the device that controls access to the network. The server is the device that verifies the identity of the supplicant.
When a supplicant wants to access the network, it sends an authentication request to the authenticator. The authenticator then forwards the request to the server for authentication. If the server authenticates the supplicant, it sends a message to the authenticator allowing the supplicant access to the network.
Why is 802.1x important for cybersecurity?
Implementing 802.1x can significantly reduce the risk of unauthorized access to your network. By requiring users to provide valid login credentials, businesses can ensure that only authorized users gain access to their network. This reduces the risk of cyber attacks, such as phishing, and prevents unauthorized devices from connecting to the network.
Moreover, 802.1x ensures that all connected devices comply with the organization’s security policies and are subject to the same level of scrutiny before granting access. This means that any misconfigured or vulnerable devices can be prevented from connecting to the network, thereby reducing the risk of security breaches.
Case Study: Marriott Data Breach
One prominent example of the need for 802.1x is the Marriott data breach that occurred in 2018. Hackers gained access to Marriott’s systems and stole over 500 million customer records, including personal information such as names, addresses, and payment card information. The hackers gained access by exploiting a vulnerability in Marriott’s systems that allowed them to bypass the company’s cybersecurity controls.
If Marriott had implemented 802.1x, the hackers would have been required to provide valid login credentials to access the network. This would have made it much more difficult for the hackers to gain access to Marriott’s systems and the customer records would have been better protected.
Conclusion
In today’s world, cybersecurity is crucial for all businesses. 802.1x is a powerful tool that can significantly reduce the risk of cyber attacks and protect your business’s reputation and finances. It ensures that only authorized users gain access to the network and prevents unauthorized devices from connecting to the network. By implementing 802.1x, businesses can ensure that all connected devices comply with their security policies and subject to the same level of scrutiny before granting access. As such, 802.1x is an essential requirement for all businesses that take cybersecurity seriously.
