Which three measures are most effective for logical database infrastructure security?

• A. Implementing robust firewall systems, establishing a secure perimeter network, enforcing strict port security
• B. Increasing physical security personnel, implementing stricter access badges, enhancing lighting in server rooms
• C. Installing antivirus software, conducting regular updates, using strong email filters
• D. Limiting user permissions, using default credentials, disabling security audits

Answer: (A)

The most effective measures for logical database infrastructure security focus on protecting the data and ensuring that only authorized users have access. The first choice outlines several critical technical controls: implementing robust firewall systems acts as a barrier against unauthorized access while enabling legitimate traffic; establishing a secure perimeter network ensures that only authenticated and trusted traffic can interact with the database environment; enforcing strict port security helps to mitigate risks associated with open ports that may be exploited by attackers. Together, these measures create multiple layers of defense against potential cyber threats targeting the logical aspects of a database, which involve access control, data integrity, and confidentiality. They are essential in establishing a secure technical environment that can withstand various attack vectors, such as SQL injection or DDoS attacks. In contrast, the other options primarily address different aspects of security. The second choice relates to physical security measures, which, while important, are not directly focused on the logical database layer. The third choice emphasizes software and general cybersecurity practices but doesn’t specifically target logical infrastructure security as strongly. The final option includes practices that would actually weaken security, like using default credentials and disabling audits, which are contrary to effective security strategies.
