Ensure portmap is not in use

中级别 1自动化aix

说明

If all RPC services are disabled, disable the portmap daemon itself. The portmap daemon is required for the RPC service. It converts the RPC program numbers into Internet port numbers. The daemon may be disabled if the server is not: 1. An NFS server 2. A NIS (YP) or NIS+ server 3. Running the CDE GUI 4. Running a third-party software application that relies on RPC support Audit: no RPC programs other than portmap/status/nsm/pyramid may be registered (portmap not running is compliant).

检查方式

审计方法: Shell 命令

shell

command -v rpcinfo >/dev/null 2>&1 || exit 1; out=$( { rpcinfo -p localhost | egrep -v "(portmap)|(status)|(nsm)|(pyramid)|(program)" ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

Review any active RPC services: rpcinfo -p localhost Run the program above (in Audit) with the argument fix check exit status (should be 0)
