Much of our Internet experience today involves user accounts that require creating a username and password. Additional measures such as requiring a mobile number or secondary email address in case of hacks are also often taken by service providers to improve security on the Internet.
Such is the nature of the Internet. Because so much information is easily accessible on the world wide web, we need to take extra precaution to ensure that what we post online remain safe.
Many businesses have chosen to move their business communication to VoIP, with the benefits it brings. But there’s a caveat. As with anything on the Internet, SIP needs to be secured and protected from fraudulent hackers.
Footing the Bill
When you pay for a SIP service, you’ll have to take steps to ensure that your account doesn’t fall prey to VoIP toll fraud. Hackers scan for weak SIP passwords and vulnerable accounts are then cracked to make calls.
It’s more than one or two times for their own personal use. Now that they have gained access to your business phone system, savvy hackers can now distribute your call service and charge for several purposes — overseas calls, chat hotlines, calling premium numbers, and the list goes on.
Call minutes are then leaked in the millions, chalking up a hefty phone bill which you definitely won’t be pleased to receive.
Prevention is Better Than Cure
To avoid finding yourself high and dry, level up your SIP security with these steps:
1. Choose a SIP service provider that offers adequate security measures.
There are many SIP service providers but it’s worthwhile to go with one that’s invested in the necessary infrastructure to secure their SIP service. Hoiio offers IP whitelist and country whitelist screening, as well as TLS and SRTP support to safeguard your SIP.
2. Implement whitelists.
Whitelists work by allowing only certain calls to be made. IP Whitelist allows calls made from authorised IP addresses, and Country Whitelist allows calls to specific authorised countries. Implementing whitelist features lets you screen calls before they are even made, and thus preventing any unauthorised calls in the first place.
3. Be vigilant about your passwords.
Your SIP account password and SIP trunk password are incredibly sensitive and can carry major consequences if leaked. Change the default password to a stronger one, and don’t reveal it freely.
4. Your phone vendors can help too.
Check with phone vendors if they have anti-hacking measures in place. For example, 3CX has in-built anti-hacking mechanisms with their Version 9.
There’s no need to risk a vulnerable SIP account. Victimised companies have been devastated by the huge phone bills, and it’s not easy to negotiate with telecom carriers because someone has to fork out the money in the end.
