Similarly, a large number of researchers had

worked on the proposed work presented in the article

that is undertaken by us. All the research gaps /

drawbacks of previous methods developed by earlier

researchers were studied in a nutshell. Some of the

commonly identified drawbacks were - use of

conventional methods, Security threats, Data being

stolen, Algorithms developed were complex in

nature, Easily hacked, Time of compilation was very

high, High computations, their traditional methods

are used, which require long compilation times and

are computationally intensive. There is a lack of

comprehensive automation of algorithms, and little

effort has been made to enhance their accuracy and

performance. Real-time hardware implementation is

rare, and few have pursued these advancements.

Additionally, there has been minimal automation of

algorithms, and insufficient work has been done to

improve both the accuracy and performance of these

algorithms, the RTI using hardware & interfacing kits

– very few people had done (Gupta and Kim, 2020).

Due to the cloud’s inherent leverage, IoT faces

numerous security challenges when transferring data

between two users, it lacked recommended

procedures for securely adopting IoT and cloud

computing at same time for identifying the culprits

when they were stealing the power., the high cost of

memory devices, staff management, and equipments

upkeep are still pressing problems for ISPs to address

the security issues in integrated electrical power

systems. In the proposed work presented in the article

that is going to be carried out, some of the above

mentioned drawbacks are going to be taken into

account & some of the afore-mentioned drawbacks

that existed in the earlier researchers' works and new

high security algorithms are going to be addressed to

overcome the shortcomings (Liu, et al. , 2020).

A sincere effort is going to be made to develop

some highly effective algorithms for the security

enhancements in integrated electrical power systems

using AI-ML-DL concepts. Effective experimental &

simulation findings are going to be produced using

the necessary software tool environments. After

carefully examining the work produced by numerous

writers, the various parameters are studied in order to

construct the integrated electrical power system and

to increase its efficiency by incorporating high

security features. This idea is regarded as the main

result of our investigation (O'Connor and Rodriguez,

2020).

4 ENHANCEMENT OF CYBER

RESILIANCES ACROSS THE

ELECTRIC VALUED CHAINS

The foundational tenets of cyber resilience, such as

instilling a culture of cyber resilience within an

organization and executing comprehensive risk

management protocols, are universally relevant

across diverse sectors and industries. Nonetheless,

these principles necessitate customization to reflect

the unique attributes and demands of specific sectors.

In the electricity sector, these distinctions encompass

the expectation of ultra-high availability in real-time,

the intricate interdependencies and potential

cascading impacts among and between systems, and

the integration of both cutting-edge technologies and

aging assets with extended lifespans. Bolstering

resilience within the electricity domain should also be

INCOFT 2025 - International Conference on Futuristic Technology

832

viewed in the expansive context of fortifying

resilience across all pivotal infrastructure and

services, including water, transportation, information

and communication technology, healthcare, and

finance (Li, et al. , 2021).

The augmentation of cyber resilience within

electricity systems is an ongoing endeavor, typically

encompassing several phases, delineated as follows:

• Identification and evaluation of risks and

preparedness levels;

• Execution of a risk management strategy to

categorize and prioritize risks and

corresponding actions;

• Adherence to stringent response and recovery

protocols in the aftermath of an attack;

• Documentation and integration of insights

gleaned from historical incidents;

• Dissemination of knowledge among pertinent

stakeholders.

Given the perpetual evolution of cyber threats, it

is imperative for all organizations to persistently

monitor and assess their vulnerabilities and risk

profiles, taking decisive actions as necessary. For

instance, some organizations may find it prudent to

engage in proactive threat hunting and leverage cyber

threat intelligence to brace themselves against

advanced threats posed by highly skilled and

determined adversaries..

5 CYBER RESILIENCES

INTEGRATION INTO THE

NETWORK SYSTEM

Figure 1:Significant cyber incidents worldwide, 2006-2019

Cyber resilience endeavors must be woven into

the organizational fabric, transcending the perception

of being merely a separate, technical concern. Absent

this integration, organizations risk inadequately

addressing the multifaceted challenges presented by

digital transformation in a comprehensive, apt, and

consistent manner. In the face of an attack, it is

paramount that organizations enact stringent response

and recovery protocols, concurrently documenting

and assimilating insights from previous incidents.

Cyber resilience constitutes a symbiosis of

preventative and remedial actions, each informed by

the aftermath of previous cyber incursions. Reflective

analysis of prior breaches is essential to guide the

enhancement of existing measures and the

formulation of novel safeguards, ensuring

adaptability and fortification as required (Nelson, et

al. , 2022).

Communication with external stakeholders is

equally imperative to augment threat awareness

within the community and to aid in identifying

overlooked vulnerabilities. Interventions by

policymakers, regulatory bodies, regulated entities,

and other stakeholders can significantly bolster cyber

resilience throughout the electricity system, ensuring

the implementation of suitable protective measures.

Numerous tools and frameworks exist to offer

guidance and bolster efforts aimed at enhancing

resilience. Significant cyber-incidents worldwide for

more than a decade from 2006 to 2019 is shown in the

Figs. 1 & 2 respectively (Thimmaraja, Nagaraja, et al.

, 2023) The proposed conceptual view to solve this

problem is shown in the Fig. 3. The Fig. 4 give some

of the steps/ideas to enhance cyber resilience in

integrated electrical power systems which are going

to implement in our proposed research work

(Nagaraja, Jayanna, et al. , 2013).

7 JUSTIFICATION

The research work presented here could be justified

by the increasingly complex and interconnected

nature of power systems in today’s digital landscape.

As societies become more reliant on electricity and

critical infrastructure, the need for a robust

cybersecurity strategy becomes imperative for

several reasons in order to arrive at the solutions of

the objectives to get the outcomes in the form of 6

justifications for the 6 objectives that are proposed

(Thimmaraja, Nagaraja, et al. , 2023).

Firstly, the digitization of power systems has

introduced new vulnerabilities and risks. With the

integration of smart grids, IoT devices, and other

digital technologies, the attack surface for cyber

threats has expanded. A comprehensive cybersecurity

strategy is essential to identify and address these

vulnerabilities, ensuring the resilience of power

systems against potential disruptions (Manjunath,

Pavithra, et al. , 2016).

Secondly, power systems are critical

infrastructure that underpins the functioning of the

different sector, comprising of the health-care,

communication, finance, and transportation. Any

disruption to the power grid due to a cyberattack can

had cascaded effect for these interconnected systems,

leading to significant social and economic

consequences. The proposed research work is

justified in its objective to protect critical

infrastructure and maintain the reliable operation of

essential services (Tomar, Manjunath, et al. , 2014).

Thirdly, the integrated approach advocated by the

proposed research work recognizes the need for a

coordinated and cohesive strategy. Traditional

isolated cybersecurity measures may not be sufficient

to counter the sophisticated and evolving nature of

cyber threats. An integrated strategy ensures that

various components of the power system work

together harmoniously to detect, prevent, and respond

to cyber incidents effectively (Hayder, Manjunath, et

al. , 2025).

Fourthly, the adaptation to the digital age is

another key justification for the proposed research

work. As technology continues to advance, cyber

threats become more sophisticated, requiring a

proactive and adaptive cybersecurity strategy. The

proposed research work aims to stay ahead of

emerging threats by continually updating and

adapting security measures to the evolving digital

landscape.

Fifthly, collaboration and information sharing

among stakeholders are crucial in addressing

cybersecurity challenges effectively. By fostering

INCOFT 2025 - International Conference on Futuristic Technology

834

cooperation among industry players, government

agencies, and other relevant entities, the proposed

research work aims to create a collective defenses

against cyber-threats. These collaborative approaches

not only enhance the entire cybersecurity postures,

but further facilitates a more rapid and coordinated

response to emerging threats.

Sixthly, the proposed research work is justified by

the economic implications associated with potential

cyber threats to power systems. Cyberattacks on

power grids can result in significant economic losses

due to downtime, operational disruptions, and the cost

of restoring systems. By implementing an integrated

cybersecurity strategy, the proposed research work

aims to mitigate the economic impact of potential

cyber incidents, safeguarding investments in power

infrastructure and maintaining the stability of the

broader economy.

In a nutshell, the overall justifications could be

summarized under 8 different headings as follows

along with their interpretations of how to achieve

those justifications.

Increasing Cyber Threats : The power sector is

increasingly becoming a target for sophisticated

cyber threats. As technology advances, so do the

methods and capabilities of malicious actors. An

integrated cybersecurity strategy is essential to

address evolving cyber threats and protect critical

infrastructure from potential disruptions.

Interconnected Systems : The power sector relies

on complex and interconnected systems, including

smart grids and industrial control systems. This

interconnectivity introduces vulnerabilities that can

be exploited by cyber adversaries. A comprehensive

cybersecurity strategy is necessary to ensure the

resilience of these interconnected systems and

prevent cascading failures.

Critical Infrastructure Importance : The power

sectors are a critical components of a nation infra-

structure, provided essential service to industries,

communities, and individuals. Any disruption to the

power grid can have cascading effects on various

sectors, leading to economic and social

consequences. Protecting critical infrastructure is not

only a national security imperative but also crucial for

maintaining societal functions.

To conclude, the justification for the researcher’s

works presented in the article falls in the need to

address the evolving cybersecurity challenges posed

by the digitization of power systems. The research

work’s objectives are grounded in the imperative to

enhance resilience, protect critical infrastructure,

embrace an integrated approach, adapt to the digital

age, and foster collaboration to ensures the security &

reliability of power system in the face of emerging

cyber threat.
