Industries worldwide have adopted VoIP, but it has its dependency on the internet for efficiency and security.
FREMONT, CA: Technological advancement has replaced traditional voice calls with voice over internet protocol (VoIP). Owing to the increasing popularity of video calls and the feasibility of using the internet, VoIP has gained its position in the market. VoIP allows users to make calls from any location and over the internet. The technology is rapidly gaining popularity due to its seamless service while making real-time communication and cost-effectiveness.
Today VoIP is preferable in industries and offices in place of landlines for any means of communication. Because of its agility, video conference and audio calls are all efficiently done using VoIP. But as technology evolves, it gives rise to several threats and dependencies. VoIP is vulnerable due to frequent cyber attacks and its reliance on the internet and power supply.
Let us understand the causes for disruptions in the VOIP service.
Poor internet connection: VoIP service is disrupted because of low bandwidth internet connection that causes hindrance in delivering data packets to the recipient. It affects the call quality.
Network congestion: Data packets fail to transfer efficiently if too many data packets are sent simultaneously. It increases network traffic resulting in slow internet.
UDP timeouts: VoIP uses several protocols with IP for the delivery of data packets to the correct recipient. VoIP uses UDP as a transport protocol for its speed. But firewalls sometimes block UDP connections to prevent security threats.
Cyber attacks: Internet services are vulnerable due to frequent cyber threats. VoIP services are mostly compromised because of distributed denial-of-service (DDoS) attacks, resulting in offline connections for a long period.
Why is VoIP vulnerable to distributed denial-of-service (DDoS) attacks?
DDoS attacks can be initiated in almost any network protocol with the help of a few hacking tools. Businesses that are unable to make phone calls will not be able to accomplish much, which gives attackers a reason to target VoIP services.
Understanding VoIP DDoS attack categories
Attacks directed at VoIP service providers: Such attacks are potentially strong enough to block all VoIP service providers. It targets their web applications and prevents them from logging in, crashing their PBX service by targeting servers, and taking down DNS resolution to stop users from navigating the website. The other forms of DDoS attacks are ransom attacks against the service providers.
Attacks directed at organizations that use VoIP: These are individual attacks on organizations that host their VoIP network. The servers of these organizations are most vulnerable to threats because they do not possess backup servers.
