A company needs to address an issue with its external DNS servers that allows an attacker to perform a full zone transfer if the IP address of a server within the BIND server's ACL configuration is spoofed. A portion of the /eteamed.conf for a BIND server is as follows: ; /etcamed.conf # External DNS BIND Configuration, Company LLC acl slave-servers { 10.0.0.12; /s1.compa.ny 10.0.0.13; /s2.company zone compa.nyt type master; ile "zonefiles/company": allow-transfer 1 slave-servers; 1) In which of the following ways should the BIND server implementation be modified to BEST mitigate this insecurity? A Change the ACL settings from IP to hostnames OB Establish a persistent TLS VPN between the master and slave servers Place sensors to collect the DNS transaction logs and send them to the Enterprise SIEM OD Implement transaction signatures
