A security engineer writes a script that computes SHA-256 hashes of critical server configuration files every night and sends an alert if any hash value has changed since the previous night. Which security goal is this control primarily designed to protect?
The script computes SHA-256 hashes of configuration files and compares them nightly to detect any unauthorized or accidental changes. This directly protects the integrity of the files by ensuring they have not been modified, which is the core security goal of integrity. Confident…Read full explanation
A security analyst is reviewing web server logs from an e-commerce application. The logs show repeated requests containing URLs with appended strings such as: `' OR '1'='1' --` and `'; DROP TABLE Users; --`. The application returned HTTP 200 responses with unexpected data in several instances. Which type of attack is most likely being attempted?
The repeated requests contain classic SQL injection payloads, such as `' OR '1'='1' --` (used to bypass authentication or extract data) and `'; DROP TABLE Users; --` (used to delete database tables). The HTTP 200 responses with unexpected data confirm that the application is vuln…Read full explanation
A company is redesigning its network to host a public-facing web application that accesses a confidential database. The security team needs to minimize the risk of a direct attack against the database server while still allowing the web server to retrieve and update data. Which network architecture best achieves this objective?
Option B is correct because it implements a tiered network architecture where the web server resides in the DMZ (a semi-trusted zone) and the database server is placed on the internal network, isolated from direct internet access. The firewall is configured with a stateful rule t…Read full explanation
