3 Checkpoint防火墙自身加固
CheckPoint为软件防火墙,需要安装在相应的操作系统上,因此自身加固需要对操作系统和防火墙软件两部分来进行。CheckPoint Firewall/VPN-1软件自身为一个安全的防火墙系统,只需安装相应的hotfix即可修补防火墙的安全漏洞。
对于操作系统而言,CheckPoint自带的SecurePlatform操作系统为进行了安全加固后的Linux操作系统,在没有启动防火墙服务时只有一个SSH服务是开放的,在启动了防火墙服务后,则默认只有管理服务器能连接上,其余访问均被丢弃,因此对于SecurePlatform不需要做加固工作。
对于另一个常见的CheckPoint支持的操作系统Solaris,需要做以下的安全修补工作:(针对Solaris 8)
(1) 安装Solaris 8 Core flavor (2) 安装Solaris 8光盘中下列包
- SUNWlibC
- SUNWlibCx - SUNWter - SUNWadmc - SUNWadmfw
- SUNWscpr - SUNWscpu - SUNWscpux
- SUNWsra - SUNWsrh - SUNWmdb - SUNWmdbx
- SUNWtoo
(3) 从Sun Solve站点安装以下补丁集
