What is detection and prevention?

In a strategy based on prevention, an organization does everything possible to reinforce its systems against attacks. In a detection-based strategy, a company's security team works proactively to identify and correct threats that have breached the organization's defenses. The Enhanced Cybersecurity Services (ECS) program makes it easier to protect IT networks by offering intrusion detection and prevention services through approved service providers. All of us, U.S.

UU. The ECS is an almost real-time intrusion detection and prevention capability, not a source of threats. CISA partners with approved service providers who have completed a rigorous system accreditation process to offer ECS. Upon approval, these service providers receive confidential, classified and unclassified cyber threat information from CISA and use it to protect their customers from ECS.

ECS is a commercial intrusion detection and prevention service sponsored by CISA and offered by approved private sector partners to any U.S. As a potential ECS customer, you can contact accredited ECS service providers directly for more information on pricing and technical requirements. The ECS service provider you choose does not have to be your Internet provider. Banking and healthcare fraud causes losses of tens of billions of dollars a year, resulting in a commitment on the part of financial institutions, a personal impact for bank customers and increased premiums for patients.

Fraud detection and prevention refers to strategies undertaken to detect and prevent attempts to obtain money or property through deception. Detection technologies are sometimes used in conjunction with prevention technologies to stop or mitigate an ongoing attack, such as intrusion prevention systems (IPS). The resulting budgetary adjustment has led some security teams to consider abandoning their cybersecurity detection technologies, which in many cases involve staff costs to manage alerts, and rely only on prevention solutions. Another area in which screening is often superior to prevention is internal commitments: a dishonest employee or, worse, a dishonest administrator.

However, if they access a file and shouldn't (such as recent access to presidential candidates' passport data), detection technologies (in this case records) can let administrators know that something is wrong. Fraud detection and prevention analyses are based on data mining and machine learning, and are used in fraud analysis use cases, such as payment fraud analysis, financial fraud analysis and insurance fraud detection analysis. . AI accelerates existing fraud detection software and tools and fraud detection machine learning models, allowing these tools to analyze massive transaction datasets with millisecond results.

And when it comes to hybrid and cloud IT environments, there is often only detection left to protect against attacks. Organizations must use tools and automation to extend as wide a network as possible to detect suspicious and malicious activity and then convert a fraction of the suspicious activities correlated to security incidents to human security professionals to analyze the threat and prioritize measures to address it. It may seem like an easy way to reduce costs, but prevention alone is not an effective defense and exposes the organization to a greater risk of not being able to detect an attack that causes more damage. The key difference is that only with detection technologies, you are still at risk, but you know what happened (and perhaps how).

Traditional fraud analysis and detection and prevention systems are programmed to detect unusual behavior, but when the latter matter, real-time fraud detection, analytics and machine learning are crucial to quickly identify and stop these fraudulent transactions. However, CISOs and IT security managers must assess the security posture as a whole, and detection plays a crucial and integral role in any effective cybersecurity framework. To combat this growing list of opportunities for fraudulent transactions, organizations are implementing modern fraud detection and prevention technologies and risk management strategies, which combine big data sources with real-time monitoring and apply adaptive and predictive analysis techniques, such as machine learning, to create a fraud risk score. .
