SSH Session Recording – A Guide

Introduction: SSH Session Recording

SSH is a cryptographic network protocol that provides security between two remote machines through an unsecured network such as the Internet. SSH uses different encryption and authentication methods that make secure connections between two machines.

Previously, users would have to use Telnet to obtain server access. Since telnet isn’t secure, and the Internet has been open to a global audience, servers connected to the Internet needed a safer way to access the shell.

Now that SSH session recording methods are available, organizations are finding it easier to protect their data. Want to find out how? Then keep reading, as we’ll go more in-depth with SSH’s properties and how it’s a benefit for small to large networks.

How Does SSH Work?

SSH session recording works by asymmetric and symmetric encryption:

• Asymmetric encryption is where both keys can be used for decryption and encryption. The server uses the client key to decrypt the data that was encrypted by the public key. Also, the server’s public key is used by the server to help decrypt the signal.
• Symmetric encryption is when one key is used for decryption and encryption of the data transferred between the server and the client.

Which One Do We Use For SSH Session Recording?

SSH uses both asymmetric and symmetric encryption. Asymmetric encryption takes up too much time and resources, so most SSH session recording connections use a symmetric recording. Asymmetric encryption is only used to share secret keys (session keys), using symmetric encryption speeds to push the communication further.

Benefits of SSH

As mentioned earlier, SSH applications are crucial for businesses that want to utilize and protect their data. SSH is used to defend your network from the following attacks:

IP Source Routing

While the majority of people use IP source routing for changing network paths once the original one fails, malicious individuals can use IP routing to make a device believe that it’s working with another device.

DNS Spoofing

DNS spoofing is a process where data is inserted into an ache database’s Domain Name System. The name server then returns a false IP address. Hackers do this so they can divert their traffic onto another machine. Once the attack is completed, they can obtain confidential and sensitive information.

Data Manipulation

Attackers perform data manipulation on your networks, routers, and other interconnected objects. The intruder either changes the network or receives the data when traveling via the network route.

Basically, we need SSH in order for our networks to survive. Without it, cyber-criminals will find it easier to steal valuable information. So be proactive and consider using SSH to keep your business growing and staying secure.

Conclusion

As the average hacker becomes savvier with advanced data extraction methods, you need to create something to keep your important files safe. SSH session recording allows you to plan for upcoming hacks, saving you thousands of dollars on repair. Thus, when using SSH, always rest assured that your network is well protected against inside and outside attacks.
