ISC 2 Credentials CISSP Question # 110 Topic 12 Discussion

The most effective method of mitigating the vulnerability of hard-coded session keys is to use the Diffle-Hellman (DH) algorithm. The DH algorithm is a key exchange protocol that allows two parties to establish a shared secret key over an insecure channel, without revealing the key to anyone else. The DH algorithm uses the mathematical properties of modular arithmetic and discrete logarithms to generate the key. The DH algorithm can be used to create a session key for each communication session, instead of using a hard-coded key that is fixed and static. This can prevent an attacker from extracting the key from the client or server applications, or from intercepting the key during the transmission. The DH algorithm can also provide forward secrecy, which means that the compromise of one session key does not affect the security of the previous or future session keys. Elliptic Curve Cryptography (ECC) algorithm, Digital Signature algorithm (DSA), and Rivest-Shamir-Adleman (RSA) algorithm are not the most effective methods of mitigating the vulnerability of hard-coded session keys, although they may be related or useful cryptographic techniques. ECC algorithm is a type of public key cryptography that uses the mathematical properties of elliptic curves to generate public and private keys. ECC algorithm can provide the same level of security as other public key algorithms, such as RSA, but with smaller key sizes and faster computations. ECC algorithm can be used for key exchange, encryption, or digital signatures, but it does not directly address the issue of hard-coded session keys. DSA algorithm is a type of public key cryptography that is used for digital signatures. DSA algorithm uses the mathematical properties of modular arithmetic and discrete logarithms to generate public and private keys, and to sign and verify messages. DSA algorithm can provide authentication, integrity, and non-repudiation, but it does not provide encryption or key exchange, and it does not directly address the issue of hard-coded session keys. RSA algorithm is a type of public key cryptography that is used for encryption, decryption, or digital signatures. RSA algorithm uses the mathematical properties of prime numbers and modular arithmetic to generate public and private keys, and to encrypt and decrypt messages, or to sign and verify messages. RSA algorithm can provide confidentiality, authentication, integrity, and non-repudiation, but it does not directly address the issue of hard-coded session keys.
