Why Cybersecurity Needs to be Adaptive? - XenonStack

Overview of Adaptive Security

The Future of Adaptive Cybersecurity involves two main areas of cloud-based applications and mobile devices have been a blessing for company potency, agility, and innovation. The mobile-cloud Combo enables employees to operate and be fruitful anywhere. However, the mobile-cloud era has produced a question for cybersecurity teams. If we examine how cybersecurity has traditionally been addressed up to this point, it’s centered on threat-centric Responses.

Today, the traditional perimeter has dissolved, primarily because of two changes within the enterprise – the rise of the mobile employee and the full-scale adoption of cloud services. Cyber activity once easy to define as “good,” but now it becomes “hazy.” Therefore, adaptive security is the solution to cybersecurity. Adaptive Authentication means the authentication process gets adapt according to the criteria, which measures the user’s trustworthiness. Adaptive security is an approach to safeguarding the system and data by recognizing threat-related behaviors rather than files and code. It is the ability to adapt and respond to a complex and continually changing environment.

A primary principle of Adaptive Security is trustworthiness, which means that the data and systems they are processing are reliable. In short, users that rely upon IT systems results in making business, and other decisions will only do if the information is accurate and the systems are available when required. Methods and data that encourage integrity are considered trustworthy. An adaptive security architecture helps to ensure integrity, enhancing a system trustworthiness.

Adaptive Defence Security Model

It is a continuous threat prevention process. Adaptive security gives real-time network security monitoring that examines and inspects carefully and thoroughly the network for irregularities, malicious transactions, and vulnerabilities. If a threat is detected, the platform automatically executes security measures that counter the risk in numerous ways. This covers the following methods –

Preventative – Preventative capabilities allow businesses to create outcomes, processes, and policies that counter-attack any cyber-attack. Functionality and procedures that fall under the prevention category should reduce the attack surface by blocking known threats before they impact the enterprise.

Detective – The detective layer of adaptive security identifies the attacks that are not caught by the preventative layer. Composed to detect attacks that sneak past prevention security, proper detection should decrease the dwell time of threats as well as any likely damage from them.

Retrospective – This layer looks for the threats that were not detected by the detective layer. During retrospective analysis, the security issues that are discovered are investigated and
restored, including forensic information, and recommend preventive measures that can be used to avoid future incidents.

Predictive – Capabilities keep the security team on alert by providing them information on the external events. This layer monitors the hacker activities externally and proactively anticipates new types of attacks against the current systems. Later, this information is used as feedback for the preventive and detective layers, thus creating a complete loop for adaptive security.

Why Cybersecurity Needs to be Adaptive?

Cybersecurity threats are becoming unfortunate in every day of life. Organizations today are looking for solutions that empower them to predict, prepare, and react proactively to the shifting landscape of cyber threats, and implementation of adaptive cybersecurity policies are becoming inevitable to achieve the goal.

Evolving Threats – As technology develops and develops over time, the cyber threats that we are facing will also evolve and are becoming more advanced. Earlier, the risks and attacks were much rarer, so cybersecurity systems were beneficial, but now those systems are completely outdated. Therefore, to keep up with evolving threats, cybersecurity systems need to be able to adapt to different scenarios and environments quickly. Business and cybersecurity teams may not be able to predict the future, but they can prepare for it.

Larger Attack Surface – As far as our data is shifted to the cloud, the chances of attacks increase day by day, i.e., the more and more of our work is being moved online, the number of access points for those looking to gain unauthorized access is increasing day by day. One of the main issues is securing the IoT devices, as the growth of IoT devices surrounds today’s environment. Therefore, to solve these problems, adaptive security will need to implement to protect business network assets, and it also helps to secure personal devices.

Benefits of Enabling Adaptive Cybersecurity

As the name specifies “Adaptive,” which means flexible. Therefore, Adaptive Security means having flexible security. This adaptable security measure helps to protect organization information. Adaptive Security architecture offers many benefits over traditional security platforms. The core of adaptive protection is continuous monitoring and analytics. This highlights that the security process should be ongoing, and visibility should be continuously analyzed.

Real-Time Monitoring and Responses – This enables the teams to move from after-the-fact analysis logs to real-time evaluation of users. As real-time assessment is enabled, so this makes a dynamic and immediate response possible.

Filtering and Prioritization – Adaptive Security allows IT teams to apply advanced analytics and machine learning processes that can detect some ongoing security breaches.

Reduce Threat Amplification – Adaptive Security limits the amount of damage a threat can cause, and it also shrinks the size of the attack surface, i.e., make the target of an attacker smaller.

Decrease Attack Velocity – Adaptive Security helps to slow the rate of attack.

Adaptive Cybersecurity Principles Overview

The following principles apply to information systems to reduce exposure to threats, contain the magnitude of risks, and counter them in a timely fashion.

Introduction to Pattern Recognition

IT systems must be capable of sophisticated pattern matching techniques to identify normal and abnormal behavior in code, command, communication protocols, etc.

Disposability – IT infrastructure

A sacrificial IT system – a system or virtual machine instance that can be eliminated if necessary – represents the concept of disposability in an IT infrastructure. Disposability enables flexibility that contributes to the overall robustness of the infrastructure.

Introduction to Anomaly Detection

An IT system must support the capability to recognize and respond automatically to abnormal behavior or known threats. The intention of using an adaptive approach to security design is to anticipate threats before they manifest themselves.

Adaptive Security Processing Architecture

Telemetry – Telemetry is gathering and monitoring of information about a system, networks, and other activities that can affect the IT infrastructure. Telemetry must be gathered in real-time to
anticipate threats effectively.

Correlation – Correlation is the evaluation of real-time telemetry data in conjunction with historical information.

Response Response mechanisms take specific actions according to a well-defined security policy and set of rules. The response often includes the modification of system configurations, system characteristics, and behavior, as well as halting systems if necessary. The goal of the response mechanism is to limit the exposure and impacts that might adversely affect service levels.

A Holistic CyberSecurity Approach

The approach described in this article provides a starting point in creating an adaptive infrastructure that can adjust and respond to potential security threats. Establishing security policies and defining baselines for “self” and “non-self” analyses are some of the first steps. Applying telemetry, correlation, and response mechanisms to process threats are critical to the effort to protect infrastructure systems and remediate effectively against attack. Ultimately adaptive security measures seek to protect against not only known threats but also to anticipate unknown viruses. Adaptive security measures continue to evolve, and there will no doubt be an improvement in the ability of an IT system to adapt and respond to a new and changing generation of threats. To move towards CyberSecurity Architecture, we recommend taking the following steps –
