You may have heard the terms SSH and SOAR thrown around in discussions about cybersecurity, but what do they actually mean? SSH, or Secure Shell, is a network protocol that provides a secure way to access and manage remote servers. It encrypts all communication between the client and server, ensuring that sensitive information like login credentials and data transfers are protected from prying eyes. On the other hand, SOAR, or Security Orchestration, Automation, and Response, refers to a set of tools and processes that help security teams manage their often overwhelming workload by automating repetitive tasks and standardizing incident response. Together, SSH and SOAR can form a powerful combination for securing your organization’s IT infrastructure and data.
What is SSH?
Secure Shell (SSH) is a cryptographic network protocol that provides secure data communication, remote shell services, and the ability to control networked devices remotely. It was created as a replacement for insecure protocols like Telnet, FTP, and Remote Shell (RSH) that sent data without encryption.
How Does SSH Improve Security?
SSH provides end-to-end encryption for data passing through a network, preventing network packet sniffing. It also provides strong authentication mechanisms that improve network security by verifying user identities. The use of Public Key Infrastructure (PKI) cryptography further enhances security since it removes the need for password-based authentication by exchanging keys instead.
How Does SSH Work?
SSH works by creating a secure tunnel between a client and a server, through which encrypted data is transferred. The server maintains a list of trusted clients and allows only authenticated users access to its services. SSH uses TCP/IP to establish a reliable and secure connection, and once the connection is established, a user can run commands on the remote system or transfer files.
What is Security Orchestration?
Security orchestration is the process of combining different security tools, policies, and procedures to provide an integrated approach to threat management. It brings together the various components of security infrastructure to provide a more coordinated response to security incidents.
