What indicates potential SQL injection and denial of service attacks in a database?

• A. Slowed response times and unusual query patterns
• B. Increased server uptime and data integrity checks
• C. Consistent user access logs and data encryption statistics
• D. Routine backups and data archiving efforts

Answer: (A)

The identification of potential SQL injection and denial of service (DoS) attacks in a database is often marked by specific signs. In this context, slowed response times are a significant indicator, as SQL injection attacks can cause databases to execute unauthorized commands or complex queries that overwhelm the server, leading to performance degradation. Unusual query patterns also serve as a red flag; for example, if a query is being executed continuously from an unexpected source or if the structure of the queries deviates from the norm, it may point to an attempted attack.

In contrast, metrics such as increased server uptime or consistent user access logs are typically associated with stable and secure operations, signaling no immediate threats. Data integrity checks and encryption statistics reflect ongoing security practices rather than indicators of attacks themselves. Similarly, routine backups and data archiving efforts imply good data management and disaster recovery practices, which do not directly indicate the presence of SQL injection or DoS attempts. Therefore, the signs of slowed response times and unusual query patterns are the foremost indicators of these potential security threats.
