Remote Access Trojans (RATs): Malicious software programs that provide a backdoor for administrative control over a target computer. Once installed on a victim's machine, these can enable an attacker to perform a range of actions, such as stealing information, installing more malicious software, or even taking control of the entire system, often without the victim's knowledge.

Remote Code Execution (RCE): A type of cyber-attack where an attacker exploits vulnerabilities in a system or application to execute arbitrary commands or code on a target machine or in a target process. An RCE attack can lead to a complete compromise of the targeted system, giving the attacker the ability to steal, alter, or delete data or use the system as a launchpad for further attacks. Preventing RCE attacks often involves regular patching, code sanitization, and effective use of firewalls and other security tools.

Remote Desktop Protocol (RDP): A protocol used to remotely connect and control a computer or network. It is commonly used for remote access to work on computers or remote administration of networks. Examples include accessing a work computer from home, remotely troubleshooting a network issue, or remotely managing servers in a data center.

Remote Job Entry (RJE): Traditionally used in mainframe and batch processing environments, RJE allows users to submit jobs to remote systems for execution. Although less common today due to advancements in computing, the concept lives on in distributed computing and cloud services.

Remote Journaling: A method used in data replication to continuously copy journal or transaction logs from one system to another, often to a geographically separate location. This ensures data integrity and immediate availability for disaster recovery, allowing quick failover with minimal data loss.

Remote key management services: The processes and protocols used to manage cryptographic keys in a remote or distributed environment. These services maintain the lifecycle of the cryptographic keys used for encryption and decryption processes, including their generation, storage, distribution, rotation, and retirement. These services help ensure the keys are securely stored and only accessible to authorized entities, thus safeguarding sensitive encrypted data.
