Masking is a technique that involves replacing or hiding some parts of sensitive information with symbols or characters, such as asterisks (*) or Xs. Masking can help safeguard the confidentiality of sensitive information while allowing limited access to authorized individuals, because it obscures the original data without altering its format or structure. For example, masking can be used to hide some digits of a credit card number or a social security number. Deidentification, hashing, or salting are other techniques that involve transforming or modifying sensitive information, but they do not allow limited access to authorized individuals.

A security analyst is reviewing the network security monitoring logs listed below and is most likely observing that 10.1.1.129 sent potential malicious requests to the web server and that 10.1.1.130 can potentially obtain information about the PHP version. The logs show that 10.1.1.129 sent two requests to the web server with suspicious parameters, such as “union select” and “or 1=1”, which are commonly used for SQL injection attacks. The logs also show that 10.1.1.130 sent a request to the web server with a parameter “phpinfo”, which is a function that displays information about the PHP configuration and environment, which can be useful for attackers to find vulnerabilities or exploit them.

A jump box is a secure computer that can be used to access a remote server or network. It acts as an intermediary between the user and the target system, and can limit access to specific IP addresses. A jump box can also provide logging and auditing of the user’s actions on the remote system. A jump box is a common solution for accessing highly sensitive servers or networks1.

A forensic analyst is conducting an investigation on a compromised server. The first step that the analyst should do to preserve evidence is to back up all log files and audit trails. This will ensure that the analyst has a copy of the original data that can be used for analysis and verification. Backing up the log files and audit trails will also prevent any tampering or modification of the evidence by the attacker or other parties. The other options are not the first steps or may alter or destroy the evidence.
