Learn how to use the access control list on internal servers and clients to protect your network from various attacks. Most security management programs can use firewalls well, filter routers and other defense tools to protect their networks from attacks by external hackers. However, the biggest enemy of your network is internal attacks. The internal access control list (ACLs) helps protect your network security from internal hazards. The internal

requirement is higher, you can disable the UDP port, of course, if this problem occurs, it is inconvenient to connect to the external server. We recommend that you use IPSec to block UDP. In protocol filtering, only TCP, UDP, and RDP protocols are allowed. Other useless protocols are not enabled.4. system firewall: Enable the IPSec Policy, perform security authentication for the server connection, and add double insurance to the server. Block some dangerous ports, such as 135 145 139 445 and UD

WebSphere Application Server has good security support. Security is simply to determine who has access to important system resources, including files, directories, programs, connections, and databases. Running WebSphere application servers in standalone mode is more secure than running as part of a WEB server. If the security requirements exceed the security provided by the WEB server, run the WebSphere Application Server in standalone mode. The following describes the use of access control tabl

Acl ACL: An access control list whose primary purpose is to add some "users" to the table and to control the behavior of those users.Case: There is a folder that project is created by the root user and has the following permissions on the file drwxrwx--- , and now a new user called John,root users just want John to have a readable executable permission for this folder, However, you do not want to change the original permissions for the file. At this time, Linux provides a user rights
