- Remanence The residual representation of data that remains even after attempts have been made to remove or erase the data. This phenomenon can occur in storage media such as hard drives or flash memory. Proper measures must be taken to ensure complete data erasure, especially when the data is sensitive, to prevent unauthorized access or data breaches. Techniques such as multiple overwrites, degaussing, or physical destruction of the storage media are commonly used to minimize remanence.
- Remediation The process of rectifying or mitigating a problem or vulnerability within a system or network. In this context, it involves taking necessary actions such as applying patches, making configuration changes, or implementing new controls to address identified issues or weaknesses. Remediation is a critical component of maintaining system integrity, performance, and stability.
- Remote access The capability of accessing a computer or a network from a distant location. This can be achieved through various technologies like Virtual Private Networks (VPN), remote desktop software, or other secure access tools. Remote access enables users to access files, data, and applications on the remote system as if they were physically present at that location, providing flexibility and enabling collaboration.
- 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 Authentication Dial-In User Service (RADIUS)A networking protocol that provides centralized authentication, authorization, and account management for users who connect and use a network service. With RADIUS, rather than managing user authentication at each network access server, it's managed from a central server. This enhances security and simplifies administration as changes like adding a user or modifying a password only need to be made one time at the central server.
- 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.
