Ten ways to safe operation of the HP network router

Router operating system network operating system HP JE074A  as vulnerable to hacker attacks. MostSMEs do not employ the router engineer, also does not have the function as a must to dooutsource. Therefore, network administrators and managers is not very understanding there is no time to ensure the safety of the router. The following is to ensure that the ten basicskills of router security.

1, update your router operating system

As the network operating system, router operating system also needs to be updated, so that the correct programming errors, software flaws and buffer overflow problems. Always check the manufacturer of your router and operating system updates the current version.

2, to modify the default password

According to Carnegie Mellon University's computer emergency response team said, 80% of the security incidents are due to weak or default passwords caused. Avoid using commonpasswords, and the use of uppercase and lowercase letters, mixed mode as the more powerful password rules.

3, disable the HTTP settings and SNMP (Simple Network Management Protocol)

Your router's HTTP settings section is easy to set up for a busy network administrators.However, this router is also a security problem. If your router has a command-line settings,disable the HTTP method and use this set up. If you do not use your router's SNMP, then you don't need to enable this feature. Cisco router has a vulnerable GRE tunnel attack of SNMP vulnerabilities.

4, block ICMP (Internet control message protocol) Ping request

Ping and other ICMP functions are very useful tools for network administrators and hackers.Hackers can use enabled on your router's ICMP function to find could be used to attack your network information.

5, disabled from the Internet telnet command

In most cases, you don't need to come from the Internet interface active telnet session. If you access your router from the internal settings will be more secure.

6, disable the IP directed broadcast

IP directed broadcast to allow for your equipment to implement the denial of service attack. A router memory and CPU to bear too many requests. The results will lead to a buffer overflow.

7, disable the IP routing and IP re orientation

Re orientation allows packets and then went out from another interface came from an interface. You don't need to elaborate packets redirected to a dedicated internal network.

8, packet filtering

Packet filtering is only allowed to enter the kind of data you transfer your network. Many companies are allowed to use only 80 port (HTTP port) and 110/25 (email). In addition, you can block and allow the IP address and scope.

9, review the safety record

By simply use some time to review the log file for you, and you will see the obvious way to attack, and even security vulnerabilities. You will experience so many attack surprised.

10, unnecessary services

Always disable unnecessary services, both routers, servers and workstations on unnecessary services to the disabled. Cisco devices default to provide some small service by network operating system, such as echo (Hui Bo), HP JD320B chargen (Character Generator Protocol) and discard (discard protocol).
