Cyber Security Very Important Question Answer

 Cyber-Security

What is inherent Risk, current risk and residual risk in Cyber security?

 

In Cyber security, these terms are used to assess and manage risks associated with potential threats and vulnerabilities:

Inherent Risk: This refers to the level of risk that exists without considering any controls or mitigation measures. It represents the risk associated with a specific system, application, or process before any security measures are implemented. Inherent risk is often assessed based on factors like the nature of the data involved, the technology used, and the potential impact of a security incident.

Current Risk: Current risk, also known as inherent risk after controls, takes into account the inherent risk as well as the existing security controls or safeguards that are in place. It reflects the level of risk that remains after considering the effectiveness of these controls. Current risk helps organizations understand their exposure to threats at a given point in time.

Residual Risk: Residual risk is the risk that remains after implementing security controls and risk mitigation measures. It represents the level of risk that an organization is willing to accept as part of its risk management strategy. Residual risk can result from the inability to completely eliminate a threat or vulnerability or from a conscious decision to accept a certain level of risk for operational reasons.

In summary, inherent risk is the initial risk level, current risk considers existing controls, and residual risk is what remains after applying those controls. Organizations use these concepts to make informed decisions about where to allocate resources for further risk reduction or to determine if they are within an acceptable risk tolerance.

 

Describe about cyber warfare , cyber crime and cyber terrorism in Cyber security 

 

Certainly, here's an overview of cyber warfare, cybercrime, and cyberterrorism in the context of Cyber security:

Cyber Warfare:

Nature: Cyber warfare involves state-sponsored or nation-state actors engaging in offensive and defensive operations in the digital realm with military or strategic objectives.

Objectives: The primary objectives of cyber warfare are often to gain a strategic advantage, gather intelligence, disrupt enemy operations, and potentially achieve physical damage through digital means.

Targets: Targets can include military infrastructure, government networks, critical infrastructure (such as power grids or transportation systems), and communication systems.

Examples: Stuxnet, a malware that targeted Iran's nuclear facilities, is often cited as an example of cyber warfare.

Cyber Crime:

Nature: Cybercrime encompasses a wide range of illegal activities conducted in cyberspace, often by individuals or criminal organizations for financial gain or personal motives.

Objectives: Cybercriminals aim to steal sensitive data, commit fraud, extort money, distribute malware, or engage in other illicit activities.

Targets: Targets include individuals, businesses, financial institutions, and any organization with valuable digital assets.

Examples: Ransomware attacks, online fraud, identity theft, and hacking for financial gain are common cybercrime examples.

 

Cyber Terrorism:

Nature: Cyberterrorism involves using digital methods to create fear, disrupt society, or advance ideological, political, or religious objectives. Unlike cyber warfare, cyber terrorism is typically carried out by non-state actors.

Objectives: Cyber terrorists seek to create chaos, intimidate populations, and damage critical infrastructure to further their cause.

Targets: Potential targets include government agencies, financial systems, transportation networks, and public utilities.

Examples: Distributed denial-of-service (DDoS) attacks on government websites, hacking into critical infrastructure systems, or spreading extremist propaganda online can be forms of cyber terrorism.

In all these categories, the evolving landscape of technology and the interconnected nature of our digital world have made it crucial for governments, organizations, and individuals to prioritize Cyber security measures to defend against cyber threats. This includes robust security protocols, incident response plans, and international cooperation to address cybercrimes and the potential consequences of cyber warfare or cyber terrorism.
