A cipher suite is a set of algorithms that defines how the encryption, authentication, and integrity of data are performed during a secure communication session. Some cipher suites are considered vulnerable or weak because they use outdated or insecure algorithms that can be easily broken or compromised by attackers. The vulnerability scan results show that the web server accepts several vulnerable cipher suites, such as RC4, MD5, or DES. The best action for the analyst to recommend to developers is to change the web server so it no longer accepts the vulnerable cipher suites and only accepts the secure ones. Changing the web server so it only accepts TLSv1.2, only accepts cipher suites using AES and SHA, or offloading SSL/TLS to a WAF and load balancer are other possible actions, but they are not as specific or effective as changing the web server so it no longer accepts the vulnerable cipher suites.

Implementing an air gap for the legacy systems is the best solution to improve their security posture. An air gap is a physical separation of a system or network from any other system or network that may pose a threat. An air gap can prevent any unauthorized access or data transfer between the isolated system or network and the external environment. Implementing an air gap for the legacy systems can help to protect them from being exploited by attackers who may take advantage of their unpatched vulnerabilities .

To prevent adversaries from intercepting response and recovery details. Using a secure method of communication during incident response is important to prevent adversaries from intercepting response and recovery details that could reveal the incident response team’s actions, strategies, or findings. If the adversaries can intercept the communication, they could use it to evade detection, escalate their privileges, or launch further attacks. To ensure intellectual property remains on company servers, to have a backup plan in case email access is disabled, or to ensure the management team has access to all the details that are being exchanged are other possible reasons to use a secure method of communication, but they are not as important as preventing adversaries from intercepting response and recovery details.
