Description

HTTP (Hypertext Transfer Protocol) is a protocol used for information exchange over the Internet, but it does not provide sufficient measures for secure communication. Therefore, sending sensitive information over HTTP means that third parties can access this information and potentially use it for malicious purposes.

To transmit sensitive information securely, it is important to use HTTPS (Hypertext Transfer Protocol Secure). HTTPS utilizes the SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocols to secure HTTP. These protocols enable data encryption and establish a secure connection. During the transmission of sensitive information, the data is encrypted and can only be deciphered by the intended recipient. This prevents unauthorized individuals from accessing the information and ensures secure communication.
Transmitting credentials in cleartext leaves them vulnerable to interception by attackers. This type of attack can occur on various network protocols, including HTTP, FTP, Telnet, and SMTP. Detecting and preventing cleartext credentials transmission is crucial to safeguard your business from unauthorized access.

Impact

Cleartext transmission of credentials can have severe consequences for your organization, including:
Compromised User Accounts: Attackers can exploit cleartext transmission to capture usernames and passwords, compromising individual user accounts. This can lead to identity theft, fraudulent activities, or unauthorized use of personal information.
Unauthorized Access: Cleartext transmission makes it easier for malicious actors to obtain login credentials. Once in possession of these credentials, they can gain unauthorized access to systems, applications, or accounts, potentially causing significant damage and unauthorized actions within your organization.

Mitigation

To prevent cleartext transmission of credentials and enhance your network security, consider implementing the following measures:

Use encryption: Utilize encryption protocols such as Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt sensitive data during transmission. This ensures that the information remains secure and unreadable to unauthorized parties.

Implement strong access controls: Establish robust access controls and authentication mechanisms to ensure that only authorized individuals can access sensitive information. Enforce the use of strong, unique passwords and consider implementing multi-factor authentication for an added layer of security.

Implement network segmentation: Employ network segmentation techniques to separate sensitive information from other network traffic. This helps restrict access to sensitive data and mitigates the risk of unauthorized interception.

Monitor your network: Regularly monitor your network traffic to detect any instances of cleartext credentials transmission. Utilize intrusion detection systems and network monitoring tools to identify and respond promptly to potential security breaches.
