TLS_AES_128_CCM_8_SHA256
Breakdown of the TLS_AES_128_CCM_8_SHA256 cipher suite
Cyber Security Rating for TLS_AES_128_CCM_8_SHA256 - A
A
Cipher
AES should be used in cipher suites because it offers strong security with efficient performance, large block size (128 bits), and resistance to known attacks. Its widespread adoption and thorough analysis by the cryptographic community ensure reliability and robustness for encrypting sensitive data.
A
Hash
Improving greatly from SHA1, SHA-256 and above create secure hashes through robust cryptographic algorithms that ensure collision resistance and preimage resistance. They process input data in fixed-size blocks, applying complex mathematical transformations that make it computationally impractical to reverse-engineer the original data from its hash.
A
Key Size
128-bit symmetric encryption keys are considered secure because they provide an astronomically large number of possible combinations (2^128), making brute-force attacks computationally infeasible with current technology. This level of security is sufficient for most practical purposes and is widely adopted in various encryption protocols.
A
Cipher Mode
CCM (Counter with CBC-MAC) is a mode of operation for cryptographic block ciphers, providing both encryption and authentication. Used in cipher suites, CCM ensures data confidentiality and integrity by combining the Counter (CTR) mode for encryption with the Cipher Block Chaining Message Authentication Code (CBC-MAC) for authentication. This dual functionality makes CCM highly efficient and secure, suitable for resource-constrained environments like IoT and wireless networks. By integrating CCM, cipher suites offer robust protection against unauthorized access and tampering, enhancing overall security in secure communications.
Web infrastructure owners must ensure they only allow secure cipher suites to protect against potential security threats. Cipher suites determine the encryption algorithms and key exchange mechanisms used in HTTPS connections. Insecure cipher suites can leave data vulnerable to interception, decryption, and manipulation by malicious actors. By restricting to secure cipher suites, owners mitigate risks such as data breaches, unauthorized access, and compromise of sensitive information. This proactive measure helps maintain trust with users, ensures compliance with security standards, and safeguards the integrity and confidentiality of data transmitted over the web.
