How To Increase
Phone System Security
We all know that there are many ways to have a more secure office, but how often do we stop and think about the phone system? All of the sensitive information you store can be accessed by hackers through your phone system. Hackers are looking for weak points in any network they infiltrate, and even if you have strong passwords on your computers, these people will find an easier way into your company. The best thing you can do is protect yourself with a secure phone system! This article will tell you everything you need to know about securing your business’s phone lines from being breached by hackers.
PBX Firmware Must be Updated
It’s no secret that modern technology is constantly changing. When it comes to PBX security, this means your first line of defense should be frequent inspections and updates for the software/firmware on your system. Do you know what happens when a bug or other potential vulnerability in an older version gets exploited? Your company could suffer from costly data breaches as well as identity theft! To avoid these types of issues, make sure to update promptly with each new release so you can protect yourself against any future attacks by hackers looking for vulnerabilities. Doing this will ensure the following:
- Protect your PBX system against attacks by hackers
- Reduce the risk of data breaches
- Updates are installed promptly and efficiently
Voice and data traffic should be separated
Separating voice and data transmission is widely acknowledged as a good way to mitigate VoIP security issues. Some phone companies provide dedicated SIP trunks with NGN ports (Next Generation Network) that may be used to segregate different types of networks, such as those for data or video, but it can also help control some aspects of the problem like separating out voice communications from other forms of digital communication. Setting up virtual local area networks on your PBX system might not always be an option, so in these cases, you would want to try using separate lines if possible instead; this will let you set one line specifically just for outgoing calls while leaving others free purely for incoming ones. Advantages of separating voice and data traffic:
- Increases security of voice data
- Makes the PBX system easier to manage
- Provides a better experience to the customer
- Protects against invasive malware
With a VLAN switch, it is possible to logically separate voice and data traffic. Even if one of these is breached, the other remains safe from outside attacks. A VLAN may also limit an assault on their network by restricting connectivity for IP telephones only at slower speeds than those used in general internet connections.
Make use of strong passwords
A strong password might be the difference between a hacked account and more time to enjoy your day. In order for hackers not to exploit any vulnerability in PBX systems, they will try every combination of letters possible until it matches what you input as your own setup protection system. A simple 8-character mix with upper/lowercase letter sets along with numerals is enough security against these probing attacks that are constantly trying new combinations via brute force programming techniques!
Change passwords on an average 2 times per year or 3 months (depending upon how often you use each one) so that attackers don’t have too much success at guessing which one was used just by looking over a few weeks ago’s projections. Strong passwords enable you to:
- Keep your data and accounts secure
- Customize passwords to match personal style
- Protect yourself from cyber theft
- Avoid deep brute force attacks that can compromise passwords
Port Forwarding should be avoided
On-premises IP PBX manufacturers advocate for port forwarding in order to provide remote access for mobile workers, but this is not a good idea. By establishing a hole in your firewall and either giving potential hackers the keys or letting them find it themselves through hacking attempts, you are essentially opening up their entire network to attack.
Instead of exposing your company’s system like that with an open door policy, put on some protection instead by using secure cloud services or putting VPN devices at both ends which will create encrypted tunnels across the public internet connections so all data sent between two points remain safe from prying eyes while being transmitted securely over networks without any chance of interception due to its encryption strength increasing exponentially as more computing power is added to each end of the tunnel.
- Protect your data by not putting it on an open port
- No more dealing with or worrying about security hacks
- Safer, more convenient remote access to your company’s business resources from anywhere in the world
- Increased efficiency and productivity of mobile employees
With a firewall, you can prevent unauthorized access
Firewall rules are important for setting up security on your PBX to prevent system access by unauthorized users. To do this, you may set firewall rules that block certain IP address ranges or even individual IP addresses and connect the phone system with a secure network connection.
- You’re in control of your security
- No more blocked IP addresses
- Keeps your phone system secure and private
Secure the PBX Trunks
PBX hacking is often done to make costly overseas calls by hijacking POTS lines or SIP trunks. The simplest VoIP security strategy for preventing this should be limiting outgoing calls from each susceptible end-point and prohibiting anonymous inbound phone calls.
A phone system security policy should be included in your organization’s overall IT Security Policy – create one today!
Is Your Office Telephone System Giving You Problems?
The first thing you should know is that your phone system may be having trouble keeping up with the demands of your business. The issues identified in this post are some pressing signs that show it doesn’t have enough capacity to handle customer requests and needs for service. This may sound like a problem, but there’s more: these same problems also make it difficult or impossible for customers to get through! When you are a business owner and your phone system is lackadaisical, it gives the competition an unfair advantage. From missed calls from customers looking for information or assistance on purchasing products (or even missing deadlines!), these same issues may place unintentional obstacles between customer satisfaction and success … preventing them from becoming loyal long-term clients worth retaining as repeat buyers in the future!
