A Red Team is a group of security professionals who simulate real-world attacks against an organization’s security defenses, to identify vulnerabilities and weaknesses. It is often used in conjunction with a Blue Team, which is responsible for defending against the attacks.
Redaction is the process of removing or obscuring sensitive information from a document or file, to protect the privacy and security of individuals or organizations. It is commonly used in legal and government documents, but also in various industries to protect sensitive data.
Redundancy is the duplication of critical components or systems, to provide a backup in case of failure. It is an essential component of high availability and disaster recovery planning, to ensure that systems and applications remain available and operational.
A Reflection Attack is a type of DDoS attack that exploits vulnerable network services to generate large volumes of traffic and overwhelm the target’s network or infrastructure. It is often used in conjunction with amplification techniques, to increase the volume of attack traffic.
Regulated Data is data that is subject to legal or regulatory requirements, such as personally identifiable information, financial data, or healthcare information. Organizations must take appropriate measures to protect this data from unauthorized access or disclosure.
Regulatory Compliance refers to the process of ensuring that an organization follows all relevant laws, regulations, and standards that apply to its operations. Compliance is important for mitigating legal and financial risks and maintaining the trust of customers and stakeholders.
A Relay Attack is a type of cyber attack where an attacker intercepts communication between two parties and relays it to another party without the knowledge of the original parties. This type of attack is commonly used to bypass authentication measures and gain unauthorized access to systems or data.
Reliability is a measure of the dependability and consistency of a system or component. In cybersecurity, reliability is important for ensuring that systems and networks are available and functioning properly to prevent downtime, data loss, or other negative impacts.
Remote Access Trojan (RAT)
A Remote Access Trojan (RAT) is a type of malware that allows an attacker to take control of a victim’s computer or device remotely. RATs are often used for unauthorized access, data theft, and other malicious activities.
Remote Code Execution (RCE)
Remote Code Execution (RCE) is a type of vulnerability that allows an attacker to execute arbitrary code on a remote system or application. This type of vulnerability can be used to take control of systems, steal data, or carry out other malicious activities.
Remote Desktop Protocol (RDP)
Remote Desktop Protocol (RDP) is a protocol used to remotely access and control a computer or device. RDP is commonly used for remote support, remote work, and other purposes, but can also be a potential security risk if not properly secured.
Remote Wipe is a security feature that allows a user to erase the data on a lost or stolen device remotely. This feature can protect sensitive data from falling into the wrong hands.
A Replay Attack is a type of network attack where an attacker intercepts and retransmits data that was previously captured in an attempt to bypass authentication mechanisms and gain unauthorized access.
Risk Assessment is the process of identifying, analyzing, and evaluating potential risks to an organization’s assets and infrastructure, including information and technology systems. This process is critical in developing an effective risk management plan.
Risk Management is the process of identifying, assessing, and prioritizing risks, and taking steps to minimize, monitor, and control those risks. This is essential in ensuring the continuity of business operations and the protection of assets.
Risk Mitigation involves taking actions to reduce the likelihood or impact of potential risks to an organization. This can include implementing security controls and procedures, improving processes, and increasing awareness and training.
A Risk Register is a document that records all identified risks, their potential impact, and the steps being taken to manage them. This provides a comprehensive view of an organization’s risk profile and helps in making informed decisions.
A Robocall is an automated phone call that delivers a pre-recorded message. This can be used for legitimate purposes, but is also commonly used for fraudulent and malicious activities, such as phishing scams.
Role-Based Access Control
Role-Based Access Control is a security model that restricts access to resources based on the roles and responsibilities of individual users within an organization. This provides granular control over access rights and helps in preventing unauthorized access.
Rogue Access Point
A Rogue Access Point is an unauthorized wireless access point that has been installed on a network. This can allow attackers to gain unauthorized access to the network and potentially compromise sensitive data.
Rogue Antivirus is a type of malicious software that is disguised as an antivirus program but in reality is designed to harm a computer system or steal personal information.
A Rogue Certificate is a digital certificate that is issued by a Certificate Authority (CA) to a malicious entity that is impersonating a legitimate organization, allowing the malicious entity to carry out attacks undetected.
