Understanding OSI layers from Security View – Introduction

Posted on by admin

The OSI model, or the Open Systems Interconnection model, is a conceptual framework that standardizes and describes the functions of a communication system. It was developed by the International Organization for Standardization (ISO) in the late 1970s to facilitate interoperability between different computer systems and networks. The OSI model is composed of seven distinct layers, each serving a specific purpose and responsible for a particular aspect of data communication. These layers work together to enable communication between devices and ensure that data is transmitted accurately and efficiently across a network.

 

 

Let’s briefly explore each layer:

  1. Physical Layer: This is the lowest layer of the OSI model and deals with the physical transmission of data over a communication medium. It defines the electrical, mechanical, and physical specifications required to establish and maintain a physical link between network devices.
  2. Data Link Layer: The data link layer provides a reliable point-to-point connection for data transmission. It handles error detection and correction, as well as data framing, addressing, and flow control. Ethernet and Wi-Fi are examples of data link layer protocols.
  3. Network Layer: The network layer is responsible for the routing and forwarding of data packets across different networks. It determines the optimal path for data transmission, performs logical addressing, and handles congestion control. IP (Internet Protocol) is a widely used network layer protocol.
  4. Transport Layer: The transport layer ensures reliable and transparent end-to-end data transfer between hosts. It establishes connections, segments data into smaller units, manages flow control, and provides error recovery mechanisms. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are common transport layer protocols.
  5. Session Layer: The session layer establishes, maintains, and terminates connections between applications on different network devices. It enables synchronization, checkpointing, and recovery of communication sessions.
  6. Presentation Layer: The presentation layer is responsible for data representation, encryption, compression, and formatting. It ensures that data from the application layer is properly formatted and compatible with the receiving device.
  7. Application Layer: The application layer is the topmost layer and interacts directly with end-user applications. It provides network services and supports protocols for specific applications, such as HTTP (Hypertext Transfer Protocol) for web browsing and SMTP (Simple Mail Transfer Protocol) for email.

By dividing the network communication process into these seven layers, the OSI model allows for modular design, easier troubleshooting, and the ability to replace or upgrade individual layers without affecting the entire system.

Understanding the OSI model and its layers is crucial for network administrators, engineers, and anyone involved in designing, implementing, or troubleshooting computer networks. It provides a common reference point for communication protocols and helps ensure interoperability in complex network environments.

Enhancing Security: PAN Removal and Secure Hashing – II

Posted on by admin

III. Keyed Cryptographic Hashing Algorithms :

To augment the security of hashed PANs, organizations can employ keyed cryptographic hashing algorithms. These algorithms incorporate a randomly generated secret key into the hashing process, significantly enhancing data protection against brute force attacks and ensuring secret authentication integrity.

HMAC (Hash-based Message Authentication Code):

HMAC is a widely used keyed cryptographic hashing algorithm that combines cryptographic hash functions with a secret key. It provides a robust mechanism to verify the integrity and authenticity of data. HMAC employs a specific hash function, such as SHA-256, along with a secret key, to generate a unique hash value for each PAN.

The process of computing an HMAC involves the following steps:

  1. a) Message Padding:The PAN is padded to ensure a consistent length, as required by the hash function.
  2. b) Key Padding:The secret key is also padded to match the block size of the underlying hash function.
  3. c) Inner Hash:The padded secret key is XORed with a predefined inner padding value, and the result is concatenated with the padded PAN. The concatenated data is then hashed using the chosen hash function.
  4. d) Outer Hash:The hashed result from the inner hash step is concatenated with the padded secret key XORed with a predefined outer padding value. The combined data is hashed again using the chosen hash function.

The final output of the HMAC process is the unique hash value that represents the PAN’s integrity and authenticity. Verifying the integrity of a PAN involves re-computing the HMAC using the stored secret key and comparing the generated hash value with the stored hash value.

CMAC (Cipher-based Message Authentication Code):

CMAC is another keyed cryptographic hashing algorithm that provides enhanced security by preventing known-plaintext attacks. It is based on a block cipher, such as AES (Advanced Encryption Standard), and employs a secret key to generate a message authentication code.

The process of computing a CMAC involves the following steps:

  1. a) Initialization:The CMAC algorithm initializes the block cipher with the secret key, setting up the initial state.
  2. b) Message Processing:The PAN is processed block by block using the block cipher’s encryption function, incorporating the secret key and the previous block’s result.
  3. c) Padding:If the PAN length is not a multiple of the block size, padding is applied to ensure a complete block.
  4. d) Finalization:The final block is processed using the block cipher, producing the CMAC value.

Similar to HMAC, verifying the integrity of a PAN using CMAC involves re-computing the CMAC value and comparing it to the stored value.

GMAC (Galois Message Authentication Code):

GMAC is a keyed cryptographic hashing algorithm primarily used in authenticated encryption schemes, providing both confidentiality and integrity assurances. It employs a secret key, a nonce (a unique number used once), and a message to generate a MAC (Message Authentication Code) that guarantees data integrity and authenticity.

The process of computing a GMAC involves the following steps:

  1. a) Initialization:The GMAC algorithm initializes the Galois field, incorporating the secret key.
  2. b) Message Processing:The PAN, along with the nonce, is processed block by block using the Galois field multiplication and addition operations.
  3. c) Finalization:The final GMAC value is generated by processing the last block and incorporating the final Galois field calculations.

GMAC enables the recipient of the PAN to validate the integrity and authenticity of the data by re-computing the GMAC value using the received PAN, the same secret key, and the nonce.

Conclusion:

In an era where data breaches and unauthorized access pose significant threats to organizations and their customers, implementing robust data security measures is crucial. Cleartext PAN removal serves as a critical defense-in-depth control, ensuring that stored PANs remain protected even in the event of an unauthorized breach. By encrypting or hashing PANs, organizations mitigate the risk of exposing sensitive data to unauthorized individuals.

Furthermore, secondary independent control systems, including cryptographic key management and governance frameworks, bolster the overall security posture. These systems ensure that access to cryptographic and decryption keys is tightly controlled, reducing the likelihood of unauthorized access and misuse.

Keyed cryptographic hashing algorithms, such as HMAC, CMAC, and GMAC, provide an additional layer of security by incorporating randomly generated secret keys. These algorithms resist brute force attacks and enhance the integrity and authenticity of hashed PANs.

By adopting these practices, organizations demonstrate a commitment to data security, safeguarding sensitive information and maintaining the trust of their customers and stakeholders. It is imperative to continually reassess and update data security measures to stay ahead of evolving threats and ensure the long-term protection of valuable data assets.

PCI DSS Network Segmentation: Explained

Posted on by admin

Network segmentation is the practice of dividing a computer network into smaller, isolated segments or subnetworks. Each segment is created to have its own distinct set of security controls and access rules, providing separation and isolation between different groups of devices, systems, or users.

The primary purpose of network segmentation is to enhance network security by reducing the attack surface and limiting the potential impact of a security breach. By segmenting a network, organizations can create barriers and control points that restrict unauthorized access and lateral movement within the network.

Network segmentation can be implemented in various ways, including:

  1. Physical Segmentation: Physically separating different network segments using separate switches, routers, or network cables. This creates a physical barrier between segments, making it harder for an attacker to move from one segment to another.
  2. VLAN Segmentation: Utilizing virtual LAN (VLAN) technology to logically separate network segments within a shared physical infrastructure. VLANs allow different groups of devices or systems to be isolated and communicate only with authorized segments.
  3. Subnet Segmentation: Dividing a network into multiple subnets, where each subnet represents a separate segment. This is typically achieved through IP addressing and subnet masks, which determine the range of IP addresses assigned to each segment.
  4. Firewall Segmentation: Implementing firewalls to enforce access controls and policies between network segments. Firewalls can filter and inspect network traffic, allowing or blocking communication based on predefined rules.
  5. Software-Defined Networking (SDN): Using SDN technologies to dynamically define and manage network segments. SDN enables flexible and programmable network segmentation based on software-defined policies and virtualized network functions.

The specific segmentation approach and techniques employed will vary depending on the organization’s network architecture, security requirements, and regulatory compliance needs.

Overall, network segmentation provides a layered defense strategy by separating and isolating critical assets, sensitive data, and different user groups. It improves network security, reduces the risk of unauthorized access, enhances monitoring and control capabilities, and helps organizations better protect their valuable information assets.

Why network segmentation is very crucial for Compliance to  PCI DSS ?

If the organization opted for Network Segmentation what is the advantages and if not what is the disadvantages for the organization while implementing PCI DSS

Network segmentation is crucial for compliance with PCI DSS because it helps reduce the scope of the cardholder data environment (CDE). By segmenting the network, an organization can isolate the systems that handle cardholder data from the rest of the network, limiting the exposure of sensitive information and reducing the potential impact of a security breach.

Advantages of network segmentation for PCI DSS compliance include:

  1. Reduced Scope: Segmentation allows the organization to limit the systems and network segments that fall within the scope of PCI DSS compliance. This simplifies the compliance process, reduces costs, and minimizes the risks associated with a broader network environment.
  2. Enhanced Security: Segmentation creates barriers and controls between different network segments, making it more difficult for an attacker to move laterally within the network. It helps prevent unauthorized access to cardholder data by isolating sensitive systems.
  3. Improved Monitoring and Control: With network segmentation, it becomes easier to monitor and control network traffic, identify anomalies, and detect potential security incidents. This enables quicker response times and more effective incident management.

Disadvantages of not implementing network segmentation for PCI DSS compliance include:

  1. Increased Risk: Without network segmentation, the entire network becomes part of the cardholder data environment, which significantly increases the risk of unauthorized access to sensitive data. A breach in one area of the network can potentially compromise the entire network.
  2. Complex Compliance: PCI DSS compliance becomes more challenging when the entire network is in scope. The organization must implement security controls and measures across a larger surface area, making compliance management more complex and resource-intensive.
  3. Higher Costs: The broader scope of compliance requires additional resources, including security tools, monitoring systems, and ongoing maintenance. The costs associated with securing and maintaining a larger network environment can be higher compared to a segmented network.

In summary, network segmentation provides significant advantages for PCI DSS compliance, including reduced scope, enhanced security, and improved monitoring. Not implementing network segmentation increases the risk of data breaches, complicates compliance efforts, and can lead to higher costs for the organization.

Is it mandatory to have Network Segmentation as per the PCI Standards ?

The Payment Card Industry Data Security Standard (PCI DSS) does not mandate specific network segmentation requirements because it is designed to be a flexible and scalable standard applicable to a wide range of organizations. The PCI Security Standards Council recognizes that different organizations have varying network architectures, infrastructures, and security needs.

While network segmentation is highly recommended as a best practice for securing cardholder data, the PCI DSS does not prescribe a one-size-fits-all approach. Instead, it provides a set of security requirements that organizations must meet to protect cardholder data, regardless of their chosen network architecture.

The flexibility allows organizations to assess their unique circumstances and determine the most appropriate methods for securing their networks. This includes evaluating the benefits and risks associated with network segmentation and deciding whether to implement it based on their specific environment, risk profile, and compliance objectives.

However, it’s important to note that even though network segmentation is not mandated, it is widely recognized as an effective security control and is strongly recommended by industry experts to enhance the security of cardholder data. Organizations are encouraged to consider network segmentation as a proactive measure to reduce the scope and impact of security breaches and improve their overall security posture.

Here are some recommended practices to consider when implementing network segmentation:

  • Identify Data Flows: Understand the flow of sensitive data within your organization. Identify the systems, applications, and network components that handle or have access to cardholder data. This will help you determine the appropriate network segments and boundaries.
  • Create Segmentation Zones: Divide your network into logical segments or zones based on the sensitivity of the data and the access requirements. Common segmentation zones include the cardholder data environment (CDE), internal networks, DMZ (Demilitarized Zone), and guest/public networks.
  • Implement Access Controls: Enforce strict access controls between network segments using firewalls, routers, VLANs, or other network security devices. Configure these devices to allow only necessary and authorized communication between segments, while blocking or limiting traffic from untrusted sources.
  • Separate Cardholder Data: Isolate systems that handle cardholder data from other non-payment systems. This can be achieved through physical or logical separation, ensuring that only authorized personnel have access to the cardholder data environment.
  • Monitor and Log Network Traffic: Deploy network monitoring and logging solutions to capture and analyze network traffic between segments. This enables timely detection of any unauthorized or suspicious activities, helping to identify and respond to potential security incidents.
  • Regularly Update and Patch Systems: Keep all network components and systems within each segment up to date with the latest security patches and updates. Regularly apply security patches to mitigate vulnerabilities that could be exploited to bypass segmentation controls.
  • Segment Wireless Networks: If your organization uses wireless networks, implement separate wireless segments for guest/public access and internal use. Apply appropriate security measures such as encryption, strong authentication, and network segregation to protect sensitive data.
  • Test and Validate Segmentation: Regularly conduct penetration testing and vulnerability assessments to validate the effectiveness of your network segmentation. Identify any gaps or vulnerabilities and address them promptly to ensure the segmentation controls remain robust.
  • Document and Maintain Segmentation: Maintain up-to-date documentation that clearly defines the network segmentation strategy, including the purpose of each segment, the allowed communication paths, and the associated security controls. Regularly review and update the documentation as network changes occur.
  • Periodically Review Segmentation: Conduct periodic reviews of the network segmentation implementation to ensure it aligns with the evolving security needs of your organization. Adjust and fine-tune segmentation controls as necessary to adapt to changes in technology, business requirements, and emerging threats.

How to check the Effectiveness of Network Segmentation ?

  • Review Network Architecture: Begin by reviewing the organization’s network architecture diagrams and documentation. This will provide an overview of the network segmentation strategy and help you understand the intended boundaries and isolation between network segments.
  • Network Scanning and Enumeration: Perform network scanning and enumeration to identify active hosts and network segments. Use tools like Nmap or Nessus to identify IP ranges, subnets, and the presence of any interconnected systems that should be isolated.
  • Traffic Analysis: Analyze network traffic to determine if there is any unauthorized or unexpected communication between different network segments. Use network monitoring tools like Wireshark or Suricata to capture and analyze network packets for any anomalies or violations of the intended segmentation.
  • Access Control Verification: Evaluate access control mechanisms, such as firewalls, routers, or VLAN configurations, to ensure they are properly configured to enforce the intended segmentation boundaries. Check for any misconfigurations or rules that allow unauthorized traffic between segments.
  • Penetration Testing: Conduct penetration testing to simulate attacks and attempts to bypass network segmentation controls. Testers should attempt to access sensitive systems or data from unauthorized network segments and assess the effectiveness of the segmentation controls in place.
  • Vulnerability Assessment: Perform vulnerability scanning and assessment to identify any potential weaknesses or vulnerabilities in the network segmentation implementation. Look for vulnerabilities that could allow unauthorized access or compromise the segmentation controls.
  • Review Policies and Procedures: Evaluate the organization’s policies and procedures related to network segmentation. Check if there are clear guidelines and controls in place for network segmentation, including change management processes, access control policies, and regular reviews or audits of segmentation configurations.
  • Interviews and Documentation Review: Interview relevant personnel responsible for network architecture, security, and operations. Review documentation, such as network segmentation plans, configuration guides, and change management records, to ensure that network segmentation is consistently applied and maintained.

By performing these testing activities, you can gain insights into the effectiveness and adequacy of the network segmentation controls implemented by the organization and identify any areas that require improvement or remediation to align with the intended segmentation objectives.

Understanding Vulnerability Assessment

Posted on by admin

In today’s digital landscape, organizations face a constant threat of cyberattacks and data breaches. To effectively protect sensitive information, it’s crucial to conduct regular vulnerability assessments. This blog will delve into the world of vulnerability assessments, explaining their significance in cybersecurity and providing insights into best practices. By understanding vulnerability assessments, you can proactively identify and address potential security weaknesses, safeguarding your organization’s valuable assets.

What is a Vulnerability Assessment ?

Let’s start with “what does Vulnerability mean? It is the inability to resist a hazard or to respond when a disaster has occurred. For instance, people who live on plains are more vulnerable to floods than people who live higher up.  A vulnerability in cyber security refers to any weakness in an information system, system processes, or internal controls of an organization. These vulnerabilities are targets for lurking cybercrimes and are open to exploitation through the points of vulnerability.  A vulnerability assessment is a systematic approach to identify, quantify, and prioritize security vulnerabilities within an organization’s systems, networks, and applications. It involves assessing various types of vulnerabilities, such as software flaws, configuration weaknesses, network vulnerabilities, and human factor vulnerabilities. By conducting vulnerability assessments, organizations gain a comprehensive understanding of their security posture and can take proactive measures to mitigate risks.

The Importance of Vulnerability Assessments

Vulnerability assessments offer numerous benefits to organizations, including:

  • Risk Identification: They help identify potential vulnerabilities and weaknesses that could be exploited by malicious actors.
  • Prioritized Remediation: By assessing the severity and impact of vulnerabilities, organizations can prioritize their remediation efforts, focusing on critical weaknesses that pose the highest risk.
  • Compliance Requirements: Vulnerability assessments play a vital role in meeting regulatory compliance requirements, as many industry standards and regulations necessitate regular security assessments.
  • Cost Savings: Proactively addressing vulnerabilities through assessments can save organizations from costly security breaches, financial losses, and reputation damage.

The Vulnerability Assessment Process

  1. Planning and Scoping: Define the scope and objectives of the assessment, including the systems, networks, and applications to be assessed.
  2. Information Gathering: Collect necessary information about the target environment, such as network diagrams, system configurations, and asset inventories.
  3. Vulnerability Identification: Utilize specialized tools to scan and detect vulnerabilities within the target systems, networks, and applications.
  4. Assessment and Prioritization: Analyze the identified vulnerabilities, assess their severity and potential impact, and prioritize them based on risk levels.
  5. Remediation and Mitigation: Develop a remediation plan to address the identified vulnerabilities, implementing appropriate security controls and fixes.
  6. Validation and Reporting: Validate the effectiveness of remediation efforts and prepare comprehensive reports outlining the findings, recommendations, and ongoing risk management strategies.

Tools and Techniques for Vulnerability Assessment

Several tools and techniques aid in vulnerability assessments:

  1. Vulnerability Scanners: Automated tools that scan networks and systems, identifying known vulnerabilities and misconfigurations.
  2. Penetration Testing: Simulating real-world attacks to identify vulnerabilities that automated scans might miss..
  3. Security Configuration Reviews: Assessing system configurations against industry best practices to identify weaknesses.
  4. Source Code Analysis: Examining application source code to identify vulnerabilities within the codebase.

Best Practices for Effective Vulnerability Assessments

To ensure successful vulnerability assessments, follow these best practices:

  • Conduct assessments regularly and systematically to maintain an up-to-date understanding of your security posture.
  • Keep vulnerability databases and scanning tools up to date to detect the latest vulnerabilities.
  • Prioritize critical vulnerabilities based on their potential impact and likelihood of exploitation.
  • Foster collaboration among stakeholders, including IT teams, management, and third-party experts.
  • Document findings, recommendations, and remediation efforts for future reference and compliance purposes.

Integrating Vulnerability Assessments into Your Security Strategy

Vulnerability assessments should be an integral part of an organization’s broader security strategy. By integrating the findings from vulnerability assessments with incident response plans, risk management frameworks, and security controls, organizations can

ensure a holistic approach to cybersecurity.

Future Trends in Vulnerability Assessment

The field of vulnerability assessment is continuously evolving. Keep an eye on these emerging trends:

Embrace vulnerability assessments as a fundamental component of your cybersecurity strategy, and you’ll be better equipped to face the evolving landscape of cyber threats.

Compliance Beyond Regulation: Business Benefits in the Long Run

Posted on by admin

Compliance goes beyond simply adhering to regulations it’s about creating a culture of ethical behavior and responsibility. By prioritizing compliance, businesses can prevent costly fines and reputational damage while building trust with their stakeholders. But compliance shouldn’t just be seen as a necessary evil. In fact, embracing compliance beyond regulation can bring long-term benefits to a business, such as improved operational efficiency, increased customer loyalty, and a stronger reputation in the market. Prioritizing compliance would help, businesses position themselves for success both now and in the future. 

In today’s business landscape, regulatory compliance is more important than ever before. Failing to comply with regulations not only leads to hefty fines and legal consequences, but it can also damage a company’s reputation and trust with customers.  However, compliance shouldn’t be viewed as a mere checkbox exercise. It has the potential to bring significant benefits to a business, particularly in the long term. By implementing a compliance program that goes beyond what is required by regulations, companies can improve their overall operations and reduce the risk of non-compliance. 

Long-term benefits for the organizations :  

  1. Reduction / elimination of regulatory/ legal issues:   
    The regulations help protect your business, your employees, and your customers. For example, security regulations exist to help protect against data breach, financial regulations are there to protect against fraud, and safety regulations are designed to keep organizations safe. Failing to adhere to regulatory compliance requirements can open you up to risks beyond fines.
  2. Improve the Organizations Reputation & Reliability: 
    Compliance lays the foundation on which the organizations build their reputation and brand image. Regulatory compliance helps the organization to protect the business’s resources and reputation. It takes time to build trust with customers, prospects, and vendors, and a big part of that centers on the organization’s ethical behavior.  The public image of a business influences its success. Non-compliance-related issues and legal problems will tarnish a brand’s image, resulting in a loss of trust among the general public—Labour Law compliance and following the social responsibility help to uphold a positive image while building consumer loyalty.  Sometimes, all it takes is one compliance misstep leading the organization to tremble the trust it has built over years. By not following compliance regulations, the organization might even face the risk of losing access to certain segments of customer base. For example, if the organization violates HIPAA regulations, it could lose access to certain insurance companies or risk its license with the state.
  3. Improved Compliance culture enhances the Productivity level: 
    Though organizations might find it difficult to meet their compliance requirements, they are expected to conduct their business duly adhering to applicable laws, rules, and regulations, including meeting HR Compliance requirements. Secured connectivity ensures the employees will never be more than an arm’s length away from their laptop or tablet to complete their job.  Failing to maintain the standards set by the law and the rules governing the business will lead to Regulatory action / legal liability. It may also damage business reputation and negatively impact productivity. Non-compliance will drain away the precious time and effort of the employees in attending to the regulatory queries , providing data, attending legal cases.  Working in a fully compliant environment will have a direct impact on the productivity of the employees.
  4. Making the Organization as “Best place to work”: 
    Failing to adhere to regulatory compliance requirements can open organizations up to risks beyond just penalties/ fines.  These compliance regulations aren’t put in place to make life more difficult (although, in reality, they often do). But compliance with regulations benefits your company as well as internal and external individuals. In those organizations where there is appropriate governance structure, defined roles & responsibilities, data privacy is in place.
    An organization where the regulatory framework/ compliance management is automated under one roof, which ensures compliance to the regulations will be supplementing the efforts of existing resources, which in turn will attract skilled resources and retain the existing talent pool with the organization, enabling the organization to make the company as “Best Place to work”.
  5. Improves the market share:   
    A regulatory compliant organization, with appropriate Business Continuity & DR plan will be able to deliver the goods/ services to its customers, in the event of a disaster in the primary site, thereby able to retain satisfied customers and attract more business/market share.  Regulatory compliance is often considered an obstacle to innovation, but it’s a critical aspect of ensuring the success and scalability. Staying compliant makes the organization more efficient, increases productivity, and saves money—leading to increased profitability over time. It also enables the business by taking advantage of opportunities when they arise. Further, organizations can also expand into new markets because regulatory compliance is part of a global strategy that gives companies the confidence to do business across jurisdictions.
  6. Improves the bottom line:  
    When an organization fails to comply with applicable regulations, it leads to Regulatory penalties, potential lawsuits, financial liability all impacting the organization’s financials.  Cyber-attacks globally increased by 125% through 2021, and increasing volumes of cyber-attacks continued to threaten businesses and individuals in 2022. The rate and cost of data breaches are increasing. Since 2001, the victim count has increased from 6 victims per hour to 97, a 1517% increase over 20 years. It is pertinent to note that being a compliant organization is the base for building a successful, ever-growing organization.

Future of Compliance- Trends and developments to watch

Posted on by admin

According to recent studies, organizations are shifting their approach to compliance risk management from treating it as a separate vertical to integrating it under operational risk management. This approach allows organizations to assess and measure risk based on residual risk, and focus on the most critical weaknesses. With increasing globalization and complex regulatory compliance requirements, managing compliance risk under the umbrella of operational risk has become essential. This integration also simplifies compliance testing, which can be a challenging task for many organizations.

Digital transformation : Factor-in the current and future trends

All organizations are seeking to get maximum value from their digital transformation. The Covid-19 pandemic has changed the way of business/operations, disrupting and giving opportunity to find new ways to face challenges by adopting to different business models, forcing to move to digitization, which means adoption of digital enablers like Artificial Intelligence (AI)- which includes Machine learning, Big data analytics, Robotic Process Automation (which requires Business Process Mapping to address overlapping process and creating process families), Internet of Things, Cloud/hybrid cloud, operating technology, augmented reality etc.

With a lot more efficiency coming into the system, regulators have also adopted these digital enablers. The above regulatory welcome change makes the corporates to improve and strengthen their compliance function using a more structured approach and digitization to avoid increasing penalties and fines (financial and non-financial) on non-compliance to regulations for their organizations as well as engaged 3rd parties. Although these enablers and technology are used in business growth and compliance, they usher in newer technology related risks, which must be mitigated. For example data/ information security and privacy related risks were not prominent earlier, they have become increasingly prominent in this age of digitization and have necessitated the need for Organizations to change and manage Compliance risk as newer regulations emerge from various regulators.

Data Privacy & security- another factor in the current and future trends

By year-end 2024, Gartner predicts that 75% of the world’s population will have its personal data covered under modern privacy regulations and predicts that large organizations’ average annual budget for privacy will exceed $2.5 million by 2024.

Adopting and implementing some cyber security related audit standards, using standard tools, certifications etc. have become the necessity of the day instead of just adopting these for regulatory purposes.

As an example- let us examine the context of the bank card end-to-end process. The process, if examined in depth, involves not only the Bank, but involves many 3rd party service providers such as card producers, payment gateway facilitators (which may be using cloud), settlement & reconciliation related facilitators etc. As these, 3rd parties may be in one jurisdiction or involve multiple jurisdictions, it becomes necessary to have the regulations driving this universe analyzed, audited under one umbrella- this task is extremely difficult.

Compliance requirements in the current environment moving rapidly to a digitized business environment

The technology operations (involving compliance to many regulations) require tools and audit to mitigate the risks. Organizations  use Security Operations Centre (SOC), Privilege Access Management (PAM), Network Access Management (NAM), Firewalls etc. for their IT infra and warrant the engaged technology 3rd parties to have these in place to mitigate risk and regulatory compliance. Further, using ISO framework/ NIST framework etc. strengthen the organizations to strengthen their IT infra with detailed audits for gaps and controls. Certifications of these agencies help the Organization to satisfy the regulator as well as retain their existing customer base. Additionally using tools like VAPT help organizations to assess the vulnerability and penetrations by rogue players against their IT infra defences  systems.

Data aggregation, data management, data analytics, data security etc. have assumed significant levels – although primarily one looks at these from an Operational risk perspective (which includes compliance risk), one requires to understand that above mentioned data related aspects accompany a lot of regulatory/global standards compliance requirements.

Some examples to address the above concerns on data/ information are say PCIDSS (on card data) HIPPA (for health records/ data of patients), GDPR (for personal data protections) etc. which are standards used globally.
