Human error is one of the biggest reasons behind data breaches, and by significantly removing this factor, organizations are making their transactions tamper-proof and less susceptible to interceptions. Blockchain is becoming synonymous with every industry vertically and is sweeping the globe as it integrates with essential business operations.

Blockchain technology is fully decentralized and uses a ledger-based system to record data and process transactions using multiple computers over networks. The best part about blockchain is that you can put any digital asset onto the chain and initiate a transaction. Unlike traditional banking systems, the data will always stay secure, and no intermediaries will be involved.

In this blog, we will explore how the banking and financial services industries are exploring various applications of blockchain. We will discuss its benefits, cybersecurity implications, and what lies ahead.

Use Cases of Blockchain in Financial Services


Blockchain is expected to revolutionize the banking business, and it’s no surprise that it is changing how customers conduct transactions. It replaces and streamlines the traditional banking processes with innovative approaches that are more secure, efficient, cost-effective, and transparent. The following are some of the ways that blockchain is revolutionizing digital banking.

1. Blockchain expedites international transfers.

Capital markets comprise issues and investors matched according to corresponding risk and return profiles. Firms suffer from a lack of stringent monitoring and regulatory practices and have liquidity risks, interest rate volatility, and other financial issues. Blockchain shows potential in transforming capital markets by eliminating operational hazards responsible for fraud and human error and reducing overall counterparty risks. The digitization and tokenization of financial products and assets make it much easier to trade, promote global inclusivity, increase connectivity, and practice fractionalized ownership, all of which reduce capital costs and increase liquidity (Consensys, 2023).

2. Blockchain creates an audit trail.

Blockchain can improve the security of banking transactions by eliminating financial fraud and data redundancies and by maintaining a clear audit trail. Thousands of ledgers protect blockchain networks; data cannot be changed unless all network users approve it. This makes it exceedingly difficult for hackers to penetrate and compromise sensitive information, thus saving victims from losses of hundreds or thousands of dollars.

Organizations may add an extra layer of protection by using VPN services to enhance security alongside blockchain services (Originstamp, 2023).

3. Blockchain reduces costs for customers and banks.

Blockchain can automate banking processes, translating to faster processing of payments, loans, and seamless transactional workflows. Poor record-keeping and reconciliation costs are very high and can potentially lead to cases of fraud. Many facets of digital transactions may be automated using blockchain, which increases productivity and reduces vulnerability to cyber threats. Financial institutions can address most of the challenges associated with speed and costs by implementing blockchain ledgers. The technology significantly reduces overheads and additional expenses by eliminating traditional paperwork involved with banking. There is no need for third parties or intermediaries.

4. Blockchain ensures compliance.

Blockchain improves network governance by standardizing processes and automating compliance. It is necessary for financial institutions to ensure that they stay compliant in the landscape of complex regulatory changes, especially when operating beyond borders. Regulatory compliance is crucial in trading and eCommerce spaces as well. Blockchain simplifies financial operations in real-time and streamlines reporting and transaction verification. Its immutable ledgers and asset digitization eliminate the risk of fraud and enable faster settlements.

5. Blockchain secures private messaging and cyber-physical infrastructures.

Hackers increasingly turn to social media to attack users and target platforms like Facebook and Twitter. Millions of accounts get breached every year due to information falling into the wrong hands, and messaging systems get intercepted. Blockchain can be used to standardize communications across various messaging channels and enhance security for enterprises. It can encrypt communications between parties and ensure that data doesn’t get intercepted.

When properly implemented, it can prevent unauthorized parties from tampering with financial transactions, eliminate identity impersonation, and safeguard digital interactions. Blockchain can be used for cyber-physical infrastructure to ensure authentication, security, and traceability. It can also simplify payment flow and prevent fraud and counterfeiting. This can help combat internal threats and prevent unauthorized access to data by ensuring overall trustworthiness and integrity.

We have seen many cases where hackers infiltrated networks and gained complete control over critical functions. Such incidents can be avoided by verifying data on blockchains for adding new entries or editing them.

Can Blockchain Help Reduce Cyber Risk?


Organizations can address potential security gaps by shifting their focus from enterprise to network-level cybersecurity. Several industry regulators can enjoy the open dialogue, and policymakers acknowledge the unique advantages of blockchain technologies, including their cybersecurity benefits. Cyber threats plague the financial industry, and as new threats emerge, it is imperative to safeguard personal information. Retail banking sectors are investing significantly in blockchain frameworks, and most new initiatives haven’t been rolled out at scale. The regulatory requirements are demanding, and the future regulation of blockchain technology will stay uncertain.

The UK’s Financial Conduct Authority (FCA) is formulating policies for using blockchain, while the United States is convinced it has inherent risks. Blockchain-based ETFs have been blocked by the Securities and Exchange Commission (SEC) in the U.S., though traditional banks lose up to USD 20 billion due to identity fraud, and blockchain ledgers help combat fraud by protecting data and preventing money laundering through automation and standardization.

Blockchain enables customers to use a unique identifier via a digital fingerprint and helps prevent the overlap of KYC and AML checks. Individual management of private keys can help customers safe keep their data and control with whom they share it (Higginson et al., 2019).

Furthermore, blockchain decentralizes financial exchanges and promotes greater interconnectedness among global financial ecosystems. While banks explore the use of permissioned blockchains, the technology’s distributed architecture increases overall cyber resiliency. This prevents sensitive information from being compromised via a point of failure or single access point.

A key feature of blockchain is its various consensus mechanisms, which improve the integrity of shared ledgers. Blockchain enhances the robustness of financial systems and makes consensus a prerequisite for network participants. All blocks in chains must be validated before new information is added or edited. It’s challenging to corrupt blockchains since participants are given enhanced transparency, and blockchains hosted on the cloud come with additional cybersecurity protections. The takeaway is that blockchain technology can improve an organization’s overall cybersecurity posture by enhancing cyber resiliency against emerging threats.

What Does the Future Hold?


The Society for Worldwide Interbank Financial Telecommunications (SWIFT) is working with banks worldwide on global payment initiatives and trying to improve the cross-border payments experience. SWIFT implements blockchain technologies by working with active providers and enabling banks to allow customers to pay with fiat currencies and cryptocurrency. Blockchain technology is being leveraged to significantly reduce the number of participants needed to resolve banking-related queries and to ensure compliance, which means we are already seeing some significant improvements.

The growth of blockchain-based payment solutions will continue to progress, and enterprises will witness the adoption of the technology at scale. Several companies are experimenting with “tokenization” to encrypt digital assets for secure transactions, though this is still in its early stages of development. Banks are using blockchain for digital fingerprinting and universal customer identification due to its decentralized nature. They will continue to disseminate information while it is updated and reduce the information burden during the authentication and verification processes. Blockchain will be used to verify firmware updates and patches and prevent unauthorized access or attempts to install malware.

Smart contracts show users the potential to automate payments by using predetermined conditions and automatically reducing fraud by reducing human interference. The technology manages complex reconciliation activities like invoice creation, financial decision-making, loan approvals, and application processing. A significant benefit of using blockchain is increased access to banking services and the opening of new economic streams to the global unbanked population (Baig, 2023).

The future of blockchain in cybersecurity for the banking industry is uncertain, but one thing is clear – it will continue to improve asset security and payment outcomes for organizations.

Enhancing Network Security: How IDS Systems Can Protect Against Cyber Attacks.

Enhancing Network Security, Cyber Attacks, EC-Council Career, EC-Council Career Prep, EC-Council Skills, EC-Council Jobs, EC-Council Prep, EC-Council Preparation, EC-Council Tutorial and Materials

Intrusion Detection Systems (IDS) are an emerging solution used for protecting data and safeguard enterprises from a variety of cyberattacks. Modern IDS systems have serious privacy issues and trigger a large volume of noise, false positive alerts, and do not do enough to track suspicious activities in networks. The rise of malicious actors, lack of encryption, and sophisticated attack strategies is overwhelming the cybersecurity landscape which means organizations need to upgrade threat detection methods and techniques. Intrusion detection systems have undergone many developments and been around for decades. They serve as a foundation to network security, help monitor network traffic, and can solve security problems that arise due to unaddressed gaps and vulnerabilities. This paper discusses how to enhance network security using IDS, common challenges faced, and what organizations can do to upgrade their IDS.

IDS to Fight Cyber Attacks


Cyberattacks can disrupt the security of today’s networks and jeopardize the safety, integrity, and reputation of organizations. There is a heightened need for enterprises to safeguard their network security and implement tools and techniques to protect their assets. Intrusion Detection Systems (IDS) are used for surveillance purposes and can secure networks by monitoring traffic for illicit traffic and malicious behaviors.

Network-based monitoring analyzes specific segments, devices, and application activities to detect and identify suspicious behaviors. IDS solutions are critical for organizations as they scan infrastructure systems for vulnerabilities, malware, and policy violations. Intrusion detection systems are different from intrusion prevention systems in terms of capabilities, where the former aims to detect and report incidents, with intrusion prevention systems focused on stopping incidents or causing security breaches.

There are many different types of IDS solutions for enterprises and most of them are customized according to business requirements. Automation in intrusion detection can perform audit trails and identify vulnerability exploits against target applications. Enterprises should upgrade their IDS to proactively detect and respond to emerging network security threats.

This blog will discuss challenges associated with modern IDS and what enterprises can do to upgrade their intrusion detection systems.

Challenges Associated with Modern IDS


Enterprises are continually pursuing faster, more accurate, scalable, and reliable detection frameworks for the latest IDS solutions. Modern IDS solutions present various challenges like unbalanced datasets, low detection rates, poor response times, and more false positives. They also suffer from usability issues and the learning curve is steep for enterprises that are not used to implementing these solutions into their business operations. Security practitioners may also face difficulties when configuring and installing IDS for the first time.

IDS systems generate a high volume of alerts which can be a significant burden to internal teams. Organizations simply don’t have the time or resources to inspect every alert. This means suspicious activity may sometimes slip through the radar.

Common challenges associated with modern IDS systems are:

  • Fragmentation – Attackers split payloads by splitting them into multiple packets and staying under the detection radar. Packets sent from one fragment can overwrite data from previous packets, and there are cases where packets are sent in the incorrect order to confuse the IDS system (Jelen, 2023). The IDS solution times out when there are lapses between transmitting data packets or unexpected disruptions.
  • Low-Bandwidth Threats – When an attack is spread out across multiple sources and occurs over a long period, it can generate benign traffic and noise, which bear similarities to that of online scanners. False positives and false negatives occur as a result, and there are instances of alert fatigue happening as well, which opens the door to more dangerous threats(Jelen, 2023).
  • Obscurity – It manipulates IDS protocols at different ports and evades intrusion detection by confusing the target host (Jelen, 2023).

Top Tips to Upgrade IDS


Upgrading an organization’s IDS begins by taking into account many considerations and making the necessary arrangements. It’s important to factor in an organization’s risk tolerance level when investing in new security measures and ensure minimal exposure to emerging risks. When legacy IDS moves to the Cloud, there is a massive increase in network traffic and network security monitoring tools are expected.

For enterprises that are switching to public and private cloud providers, legacy IDS may not support the latest deployment models. A security information and event management (SIEM) system can help organizations gather information from multiple sources, including intrusion detection solutions, firewall logs, and web applications. Analysis of firewall data can detect unwanted configuration changes, prevent unauthorized access to data, and ensure adherence to the latest compliance standards like DSS, SOX, GLBA, and HIPAA.

In the last few years, Machine Learning and AI have greatly expanded the scope of intrusion detection and prevention, and experts are evaluating the latest IDS techniques to assess the state of organizational security.

AI-Based Detection and Next-Gen Firewalls


AI-based detection is popular for its pattern-recognition techniques and intelligent threat analysis. It can crosscheck intrusion signatures with a signature database that contains older signatures and inspects it to find sequences, commands, and actions in networks which may identify as malware. (Khraisat, 2019)

Increasing the precision of Intrusion Detection Solutions (IDS) is important as threat patterns become increasingly complex. The most common type of IDS deployed to maximize security is the NIDS which is based on ruleset and protocol violation techniques. There are new approaches to identifying network attack events and machine learning techniques can assist with zero-day attack prevention and false-positive reduction in large-scale enterprises, thus preventing attacks in the early stages. (Regino Criado, 2022)

Next-generation firewalls (NGFW) can deep filter threats and enable micro segmentation in networks for effective intrusion prevention. They usually come as standalone products and most next-gen firewalls are integrated with virtual machines and cloud services. NGFW solutions can feature built-in IDS and IPS and have the ability to receive real-time threat intelligence from external sources. Enterprises can add new security features to them as needed, apply security policies on an application-level, and enjoy quick integrations with existing infrastructure assets. An alternative to using NGFW solutions is using Unified Threat Management (UTM) platforms which serve as a universal gateway and combine multiple security solutions.

Best Practices for Intrusion Detection


A good practice is to use multiple layers of intrusion detection technologies to prevent malicious actors from hijacking systems. There are 4 main intrusion detection approaches employed for this: wireless, network behaviour analytics, host-based detection, and network-based attack detection. Hybrid and ensemble intrusion detection models can provide reduced false positive rates and higher accuracy in anomalous threat detection. Machine learning algorithms and feature selection are popular computing methodologies used to improve the performance of intrusion detection systems. Tree-based algorithms can be used as a base classifier, and bagging and boosting are popular ensemble techniques for evaluating various datasets. They also offer excellent classification accuracy and performance when working with selected feature subsets.(Ngoc Tu Pham, 2018)

IDS research recommends the Bayesian and infinite bounded mixture model for the feature classification of members. It is also designed for IoT environment security and can help classify network activities into abnormal and normal classes. A Support Vector Machine (SVM)is a supervised machine learning technique used for making threat predictions and can be used for non-linear feature mapping (Khraisat, 2019). It’s very effective in high-dimensional spaces and can cluster data before the classification process begins.

Virtual patching should be used to protect and remediate vulnerabilities in critical systems. Most organizations adopt a hybrid cloud model for protecting their data across on-premises and cloud environments. AI-based IDS solutions integrate with multiple security products and offer features such as deep packet inspection, URL and on-box SSL inspection, and advanced malware analysis. Having customizable post-scan actions and policies that can be automated can efficiently help protect organizations from various cyber threats as well. (Micro, 2022)

Integrating IDS and IPS Capabilities Under SIEM


Intrusion Prevention Systems (IPS) are essential for improving network visibility and can help identify potential risks. IPS can detect and block unknown threats in real-time and augment the capabilities of modern IDS solutions. Other advantages include correcting cyclic redundancy check errors, eliminating instances of unwanted network layers, and resolving TCP (Transmission Control Protocol) sequencing issues. SIEM connectivity to IPS and IDS can make significant improvements to enterprise security and enable advanced threat protection. SIEM systems can take data from IPS and IDS to give a comprehensive analysis of an enterprise’s security posture and make accurate vulnerability assessments.

Many businesses are relying on managed security services providers (MSSP) to better manage their SIEM systems and ensure regular updates. Detecting and reacting to threats aren’t enough and intrusions start with simple vulnerabilities like outdated software, open ports, and unrestricted limits to login attempts. Persistent malware intrusions are subtle and don’t trigger alarms and careless practices at work like overusing privileged accounts, visiting unsafe websites, and remaining logged in for long periods of time, can set up organizations for new data breaches. SIEM solutions combined with IPS and IDS can detect such habits, tighten security, and prevented unusual account usage patterns, thus helping enterprises prevent cyberattacks and improve security effectively. (Miller, 2020)

Monitoring north-south traffic in cloud-based infrastructures is increasingly important as applications are deployed over multiple data centers and cloud platforms. Enterprises should use VPN to control the flow of north-south traffic and implement the Secure Socket Layer (SSL) protocol to encrypt data transmitted between clients and servers and secure connections. East-West traffic security monitoring inspects activities that occur laterally within network perimeters and mitigates risk for distributed operations. The best practices for efficient east-west IDS security are – applying network segmentation and performing granular inspection of East-west traffic using policy-based controls. Advanced malware analysis and sandboxing will also prevent zero-day attacks and provide accurate threat detection in the process.

Conclusion

IDS capabilities in attack detection depend on simplifying large datasets and selecting the most influential features to improve its model’s accuracy and performance. Different IDS algorithms can dramatically improve the performance of intrusion detection systems, and it’s clear that ML algorithms like DT, KNN, ANN, BN, and SVM all offer unique characteristics and features that enable IDS optimization and enhancement. When IDS is combined with machine learning and AI, its accuracy in detecting R2L and DoS network-based threats dramatically increases. The speed of the training and testing process is another significant factor in improving IDS models, along with the appropriate selection of parameters to improve detection accuracy. Enterprises can also adopt the approach of hybrid data optimization based on ML algorithms and use data sampling techniques to isolate outliers. With the proper modeling strategy, IDS performance can be upgraded, uncover hidden threats in real-time, and detect unknown types of anomalous behaviors in networks as well.

Principle of Information System Security : Security System Development Life Cycle

Security System Development Life Cycle, Security, EC-Council Career, EC-Council Skills, EC-Council Jobs, EC-Council Prep, EC-Council Preparation, EC-Council Guides

Security System Development Life Cycle (SecSDLC) is defined as the set of procedures that are executed in a sequence in the software development cycle (SDLC). It is designed such that it can help developers to create software and applications in a way that reduces the security risks at later stages significantly from the start. The Security System Development Life Cycle (SecSDLC) is similar to Software Development Life Cycle (SDLC), but they differ in terms of the activities that are carried out in each phase of the cycle. SecSDLC eliminates security vulnerabilities. Its process involves identification of certain threats and the risks they impose on a system as well as the needed implementation of security controls to counter, remove and manage the risks involved. Whereas, in the SDLC process, the focus is mainly on the designs and implementations of an information system. Phases involved in SecSDLC are:

◉ System Investigation: This process is started by the officials/directives working at the top level management in the organization. The objectives and goals of the project are considered priorly in order to execute this process. An Information Security Policy is defined which contains the descriptions of security applications and programs installed along with their implementations in organization’s system.

◉ System Analysis: In this phase, detailed document analysis of the documents from the System Investigation phase are done. Already existing security policies, applications and software are analyzed in order to check for different flaws and vulnerabilities in the system. Upcoming threat possibilities are also analyzed. Risk management comes under this process only.

◉ Logical Design: The Logical Design phase deals with the development of tools and following blueprints that are involved in various information security policies, their applications and software. Backup and recovery policies are also drafted in order to prevent future losses. In case of any disaster, the steps to take in business are also planned. The decision to outsource the company project is decided in this phase. It is analyzed whether the project can be completed in the company itself or it needs to be sent to another company for the specific task.

◉ Physical Design: The technical teams acquire the tools and blueprints needed for the implementation of the software and application of the system security. During this phase, different solutions are investigated for any unforeseen issues which may be encountered in the future. They are analyzed and written down in order to cover most of the vulnerabilities that were missed during the analysis phase.

◉ Implementation: The solution decided in earlier phases is made final whether the project is in-house or outsourced. The proper documentation is provided of the product in order to meet the requirements specified for the project to be met. Implementation and integration process of the project are carried out with the help of various teams aggressively testing whether the product meets the system requirements specified in the system documentation.

◉ Maintenance: After the implementation of the security program it must be ensured that it is functioning properly and is managed accordingly. The security program must be kept up to date accordingly in order to counter new threats that can be left unseen at the time of design.

These are the steps that are involved in the SecSDLC cycle with their brief description.

What Is Virtual Network Security, and How Can It Help Thwart Threats?

Virtual Network Security, EC-Council Career, EC-Council Skills, EC-Council Jobs, EC-Council Tutorial and Materials

In today’s digital age, securing your network is more critical than ever. But what does that mean? How can you be sure your business is protected? Virtual network security is a comprehensive approach to safeguarding your systems and data. By setting up firewalls and other security measures, you can rest assured that your confidential information is safe from prying eyes.

How Do Virtual Networks Work?


Most people have heard of virtual networks but don’t understand how they work. A virtual network is a network that exists only in software and is not physically connected to any hardware. Virtual networks are created by using a software program to simulate the functions of a physical network.

Virtual networks are often used to test new networking configurations or applications without deploying them on physical hardware. This can be very useful for developers who want to try out new ideas without affecting live systems. Virtual networks can also create isolated environments for security testing or other purposes.

What Is Virtual Security?


Virtual security is the process of protecting computer networks and data from unauthorized access or attack. It includes hardware and software technologies, policies, and procedures designed to protect network resources from unauthorized users. Standard measures used to achieve virtual security include firewalls, intrusion detection systems, and encryption.

The term “virtual security” is often used interchangeably with “cybersecurity,” but there are some critical distinctions between the two. Cybersecurity focuses on protecting computers and networks from malicious attacks, while virtual security encompasses a broader range of threats (Riddell National Bank, 2022).

Virtual security is a relatively new field that is constantly evolving to keep up with the latest technological advances. As more businesses move their operations online with products like a virtual private cloud in AWS, the need for effective virtual security measures will only continue to grow.

Virtual Network Security Measures


Many different virtual network security measures can be taken to protect your network and data. Some of the most common include:

◉ Implementing a firewall: A firewall can help block unauthorized access to your network, control traffic flows, and protect against malware.

◉ Using encryption: Encryption can help to protect data in transit as well as at rest.

◉ Creating user accounts and permissions: You can control who has access to which parts of your network by creating user accounts and assigning permissions.

◉ Monitoring activity: Monitoring activity on your network can help you to detect suspicious activity and take appropriate action.

The Difference Between NSG and Azure Firewall


Azure Firewall is a managed, cloud-based network security service that filters and monitors traffic passing through a virtual network or virtual private network. It provides Fortinet’s next-generation firewall capabilities in the cloud. Azure Firewall uses a static public IP address for your virtual network resources to communicate with the internet, eliminating the need for complex network security rules.

Azure Firewall is highly available and scalable, and it integrates with Azure Monitor for comprehensive logging and analytics. It is a stateful firewall that tracks all connections passing through it and ensures that only authorized traffic is allowed. Azure Firewall can be deployed in its dedicated subnet or shared with other applications in the same subnet (vhorne, 2022).

NSG is a networking security group that allows you to control traffic flows to and from your Azure resources. NSG can be applied at the individual resource level or the subnet level. NSG can only be used to control inbound and outbound traffic; it cannot filter traffic as Azure Firewall can.

How Virtualization Helps Improve Security


By abstracting the underlying hardware, virtualization can help improve security in several ways.

◉ First, by using server virtualization, businesses can segment their networks to isolate sensitive data from less secure parts of the network. This reduces the risk of data breaches and makes it easier to contain and fix any problems.

◉ Second, network virtualization can help improve security by making it easier to create and manage secure networks. When all network traffic is routed through a central gateway, monitoring and controlling what is happening on the computer’s VPN becomes much simpler. This can help prevent malicious activity such as malware or denial-of-service (DoS) attacks.

◉ Finally, desktop virtualization can help improve security by making it easier to manage and secure desktop systems. By keeping all data and applications on a central server, businesses can easily ensure that only authorized users can access specific data and applications. This can help prevent data leaks and unauthorized access to sensitive information (CyberExperts.com, 2020).

Virtualization is not a silver bullet for security problems, but it can be a helpful tool in improving security for businesses of all sizes, like using a VPN in networking. Virtualization can help segment networks, simplify network management, and secure data and applications when used properly.

Virtual Network Security: Key Takeaways


The cloud has transformed how businesses operate and opened new opportunities for organizations of all sizes. However, a greater need for security comes with increased cloud services. This is particularly true when it comes to virtual networks, which are used to connect devices and systems in the cloud.
There are several security risks associated with virtual networks, but there are also many ways to mitigate these risks. Below we will look at some key takeaways regarding virtual network security.

1. Virtual networks provide a higher level of security than traditional physical networks.

2. They can be easily segmented and isolated, making it difficult for hackers to access sensitive information.

3. Virtual networks can be monitored and controlled more easily than physical ones, making detecting and preventing attacks easier

4. The use of encryption can further increase the security of virtual networks.

5. Virtual network security is an integral part of the overall cybersecurity strategy.

There are several other factors to consider regarding virtual network security; however, the key takeaways discussed above should give you a good starting point on your virtual network.

Training in Virtual Security with C|ND


It’s essential to have strong virtual security training. EC-Council’s Certified Network Defender (C|ND) program is the only network defense course in the market that is 100% focused on

network security and defense. C|ND v2 has earned a reputation as the most comprehensive and effective training for IT professionals looking to harden their systems against today’s threats.
