How to Inspect Encrypted Traffic

 

Encryption is a way of encoding information or messages in ways that only the authorized parties can read. The encryption does not prevent interception but it denies every information and message content on the interceptor. In the scheme of encryption, the information or the message is being referred to as the plaintext which is encrypted through the use of the encryption algorithm. It used for protecting messages and information. It is also used in order to protect data like the files in the computer as well as the storage devices. In order to securely protect your data, inspect encryption regularly.

Encryption has two different types, the symmetric and the public key encryption. In the scheme of symmetric key encryption, the encryption and the decryption are almost the same however both the communicating parties are required to have the same key so that they can achieve the secret communication. In the scheme of the public key, encryption key is being published in order to encrypt messages however the receiving party will only be capable of reading the messages because they have the access on decryption key. What would be the ways on how to inspect encrypted traffic?

The SSL encryption for organizations is considered as a double-edge-sword. It strengthens the security by means of providing message integrity and confidentiality. It enables the users to verify the identified application of the owners and it also allows application that will authenticate users through client certificates. The encryption has now becoming more essential in protecting data and the users from threats such as phishing, data theft and snooping. The following are examples on how to inspect encrypted traffic:

  • Use SSL Server Private Keys The use of the SSL Server Private Keys to inspect encryption is a good move to attain security. You just have to copy the SSL server private key into your IDP SSL key store. IDP device makes use of the key in order to decrypt inbound traffic and to inspect payload. Private Key should be in the Privacy-Enhanced Mail format.
  • Use Root Certificate Authority for SSL Forward Proxy Operations This method makes use of the RCA or root certificate authority in order to proxy SSL negotiation. IDP inserts itself in the SSL key negotiation phase in order to inspect traffic, session and payload and to decrypt HHTP session with accordance to the security policy.
  • Through the Supported SSL Specification

The IDP Series generally support the decryption of the HTTP traffic which uses the TLSv.1 and SSLv.3. IDP Series has the capability to inspect SSLv.2 header for such anomalies however it cannot examine and decrypt HTTP payload sessions. The IDP series does not also support the inspection of the compressed TLS traffic.

It is very important to inspect encryption if you want to protect and secure internet communication for any threats and a form hacker. Information will be protected from malicious individuals and it will turn unreadable to the unauthorized users. Traffic inspection and SSL encryption will no longer be complex for both the parties. To inspect encryption, users must make sure to connect enterprise inspection appliance to the place where the information can be de-encrypted.
