CompTIA CS0-002 Exam Dumps - Actual Questions Answers

The line from this output that most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key is TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits). This line indicates that the cipher suite uses Diffie-Hellman ephemeral (DHE) key exchange with RSA authentication, AES 128-bit encryption with cipher block chaining (CBC) mode, and SHA-1 hashing. The DHE key exchange uses a 1024-bit Diffie-Hellman group, which is considered too weak for modern security standards and can be broken by attackers using sufficient computing power. The other lines indicate stronger cipher suites that use longer key lengths or more secure algorithms.

A firewall is a device or software that monitors and controls incoming and outgoing network traffic based on predefined rules or policies. A firewall can help prevent unauthorized or malicious traffic from entering or leaving a network, and protect network resources from external threats. Placing a firewall in between the corporate network and the guest network can help prevent a guest device from infecting machines on the corporate network or taking down the company’s single internet connection, as it can block or filter any unwanted or harmful traffic from the guest network.

The security analyst should set up a PKI (Public Key Infrastructure) between Company A and Company B and exchange shared certificates between the two entities. This will allow them to establish a more automated approach to secure data transfers between their ERP systems. A PKI is a system that provides encryption and authentication services using public key cryptography. A PKI consists of certificates, certificate authorities (CAs), and other components that enable users to securely exchange data over untrusted networks. By exchanging shared certificates between Company A and Company B, they can verify each other’s identity and encrypt their data using public and private keys.
