'''Tech Update
Security
Security Best Practices'''
Security is a serious concern for any application on a network. There is no shortage of
potential intruders intent on stealing services and otherwise causing problems with your
system.
IPitomy has designed several security features into the systems to thwart those threats and
to avoid the shock of getting hacked. Proper use of security and adhering to a diligent
security policy is your best way to avoid security breaches.
Here is a list of Best Practices to implement when installing an IP PBX System. Keep in
mind that if users have access to the management interface and can add extensions or
change passwords, they should be made aware of the best practices as well.
Passwords
Passwords are the key to hacking into anything. Avoid using passwords that are dictionary
words or number strings like 1234, 1111 etc. Never use words that can be associated with
you or your business. IPitomy generates random strong passwords when a SIP account is
created. It is recommended that those SIP passwords remain strong if modified.
A strong password has a combination of upper and lower case characters including
numbers and punctuation characters.
All users should be reminded that the PIN number for their mailbox should not be their
extension number. The default password for the system administration should always be
changed.
Port Forwarding
If you are not using remote phones, turn off any unused port forwards.
LA� vs. WA�
Always ensure local extensions are set to LAN.
Access Control List (ACL)
This controls which IP addresses are allowed to be connected to the system. Unauthorized users are dropped before they get a chance
to try anything.
Create a Class of Service for Remote Phones
Clone the default class of service and remove access to international dialing.
International Dialing
Remove international dialing or restrict it to only users who require it. If you don't use it, restrict it.

		+	Log Watch + Ban Service: scans log files and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Log Watch + Ban is able to reduce the rate of incorrect authentications attempts however it cannot eliminate the risk that weak authentication presents.
		+	IP Addresses will remain in the ban list until the service is reloaded or restarted.
