Description: SYN assault safety, which includes decreasing the quantity of SYN-ACK re-transmission, distribution of sources to minimize the retention time. Route cache entry sources allocation delayed until a connection is produced. If synattackprotect = 2, then the connection directions AFD three-way handshake continues to be delayed to total. Notice that only TcpMaxHalfOpen and TcpMaxHalfOpenRetried set from assortment, the safety measures will likely be taken.
5) prohibit the C $, D $ Default share
a class
HKEY_LOCAL_MACHINE System CurrentControlSet Expert services lanmanserver
ParametersAutoShareServer, REG_DWORD, 0x0
6) prohibit the sharing of ADMIN $ default
HKEY_LOCAL_MACHINE System CurrentControlSet Expert services lanmanserver
ParametersAutoShareWks, REG_DWORD, 0x0
seven) restrict the IPC $ default share
HKEY_LOCAL_MACHINE Method CurrentControlSet Manage
Lsarestrictanonymous REG_DWORD 0x0 default
0x1 anonymous consumers can not enumerate the local user list
0x2 anonymous consumers can't connect the device IPC $ share
Note: do not suggest the use of 2, might cause a few of your service doesn't begin, such as SQL Server
eight) do not assistance the IGMP protocol
HKEY_LOCAL_MACHINE Method CurrentControlSet Expert services Tcpip

ArpCacheMinReferencedLife REG_DWORD 0-0xFFFFFFFF (seconds, default is 600)
Observe: If ArpCacheLife higher than or equal ArpCacheMinReferencedLife, the reference or references ARP cache entries expire in ArpCacheLife seconds. If ArpCacheLife much less than ArpCacheMinReferencedLife, doesn't refer to items inside the ArpCacheLife seconds expire, and references to things inside the ArpCacheMinReferencedLife seconds period. every time the outbound packet to the entry for the IP deal with, it'll refer to ARP cache entries.
ten) prohibit the dead gateway monitoring
HKEY_LOCAL_MACHINE Program CurrentControlSet Expert services: Tcpip
ParametersEnableDeadGWDetect REG_DWORD 0x0 (default is ox1)
