Vulnerabilities of the classical
\nIP telephony<\/b><\/p>\n<\/div>

Definitely, the use of IP-telephony is more profitable than traditional. There is a wide additional functionality, and the cheapness of calls, and the management of remote offices, and the high quality of communication, and a single information field within the team, and a reporting system, and much more.<\/p>\n

However, the \u201ccloudy\u201d location of classic VoIP telephony can create dangers that did not exist before its invention: data interception, DDoS attacks, unauthorized access to the corporate network. Despite the fact that 99% of companies do not encounter such problems in practice, you need to be aware of them.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Due to the peculiarities of IP telephony, an attacker does not need physical access to the data line to intercept data. Moreover: external listening is almost impossible to trace.<\/p>\n

Another danger is the possibility of changing the transmitted data.<\/p>\n

Under such conditions, the entire unencrypted voice stream is insecure.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

By refusing to use or simplifying the authentication and authorization mechanism in IP telephony, you allow attackers to replace user data with their own (hacking through brute force or listening to unsecured channels).<\/p>\n

Thus, criminals can make expensive calls at your expense, or intercept and record conversations.<\/p>\n<\/div><\/div><\/div>

One type of attack is a Denial of Service (DoS) attack, which aims to exceed the load limit through information garbage or many short calls.<\/p>\n

If signs of such attacks are not monitored and passive protection measures are not applied, IP telephony servers cannot cope with the increased load and are unable to serve connected subscribers.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Why security is
\nmodern gold?<\/b><\/p>\n<\/div>

The development of modern technologies gives a huge advantage not only for business, but also for hackers. Every year they find more and more sophisticated ways to get personal data. And this is not even to mention the fact that all your calls can be tapped and recorded by the provider at any time.<\/p>\n

But is there a way to be 100% safe? Definitely!<\/p>\n

Stream Telecom brings you a wide range of encryption technologies ranging from VPN tunnels to international encryption standards.<\/p>\n<\/div>

Level 1 Encryption<\/b><\/p>\n<\/div>

Using VPN Tunnels<\/p>\n<\/div>

The most common solution for additional protection of IP telephony is the connection of remote users through virtual private networks (VPNs).<\/p>\n

The subscriber gets access to a virtual VoIP channel within the Internet. This channel is secure and allows you to receive and send information securely, making it unusable for mercenary or criminal purposes.<\/p>\n

Unlike standard telephony, the content of intercepted packets sent over encrypted VPN tunnels is clear only to the owners of the encryption key.<\/p>\n

The same method applies to secure connections to IP telephony service providers.<\/p>\n<\/div><\/div><\/div>

Level 2 encryption<\/b><\/p>\n<\/div>

Cryptographic protocol TLS protocol SRTP<\/p>\n<\/div>

To protect confidential conversations as much as possible and minimize the possibility of information falling into the hands of an attacker, you can use double protection.<\/p>\n

Since in order to make a call, the client and the server first exchange service data to establish a connection, this problem can be divided into two parts – the protection of IP telephony service data and the protection of voice traffic.<\/p>\n

TLS (Transport Layer Security) and SRTP (Secure Real Time Protocol) can be used as a means of protection.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div><\/div><\/div><\/div><\/div>

Benefits of SRTP Encryption<\/p>\n<\/div>

<\/div><\/div><\/div>

SIP signaling protection<\/p>\n<\/div>

<\/div><\/div><\/div>

Voice traffic protection<\/p>\n<\/div>

<\/div><\/div><\/div>

TLS is a cryptographic protocol that provides secure data transfer between nodes on a network. This is the standard method for encrypting the SIP protocol. TLS ensures the confidentiality and integrity of the transmitted information, provides authentication.<\/p>\n

After a secure connection is established, voice data transmission begins, which can be secured using the SRTP protocol.<\/p>\n<\/div>

<\/div><\/div><\/div>

The SRTP protocol is considered one of the best ways to secure IP telephony based on Asterisk IP PBX. The main advantage is the absence of any influence on the quality of communication.<\/p>\n

Each call you make is assigned a unique code, which makes it almost impossible for unauthorized users to eavesdrop on conversations. As a result, SRTP is the protocol of choice for both regular and confidential calls.<\/p>\n<\/div>
