DevSecOps: The Future of Secure Software Development

Aggregated on: 2023-03-14 16:29:56

As a software developer with over a decade of experience, I've witnessed firsthand the evolution of software development practices. One such practice that has gained significant traction in recent years is DevSecOps. In my opinion, DevSecOps is a necessary evolution of software development practices in response to the growing cybersecurity threat landscape. The traditional approach to software development involved developing software first and then conducting a security review of the software afterward. Unfortunately, this approach was prone to security vulnerabilities, leading to data breaches and other cybersecurity risks. DevSecOps, on the other hand, incorporates security into the software development process from the beginning.

Aggregated on: 2023-03-13 21:59:56

Site reliability engineering (SRE) is the practice of applying software engineering expertise to DevOps and operations problems. SRE, which was popularized by the 2016 publication of Site Reliability Engineering: How Google Runs Production Systems, often means proactively writing code and developing internal applications to combat reliability and performance concerns. In SRE, service levels describe services provided to users within a given period of time in measurable terms. Service level objectives (SLOs) are the goals set for the availability expected out of a system. Service level indicators (SLIs) are the key measurements and metrics to determine the availability of a system. Service level agreements (SLAs) are the legal contracts that explain what is agreed upon and what happens if systems don’t meet SLOs.

Challenges and Checklists While Migrating COTS Application to Cloud

Aggregated on: 2023-03-13 19:44:56

The world is moving rapidly towards digitization with a cloud-native approach. The first step towards this journey is migrating the applications to the cloud, preferably with re-host and re-platform disposition. While custom applications are comparatively easier to migrate, a bigger challenge, analysis, and decision arises w.r.t to COTS (commercial off-the-shelf) applications. This blog discusses critical challenges and a checklist approach before one starts COTS migration. The term ‘modernization’ used here refers to replacing and enabling the legacy product with a cloud-compatible version. Challenges and Checklists Roadmap to retain/replace/retire the Product — Answers to the following queries may lead to retain/replace/retire the product and potential application consolidation and rationalization (to be run as a separate enterprise program, outside migration) Are business/end users using this product frequently as a business-critical application? Is this product/application being used locally or globally (the same app/product is set up in different regions/countries and being used almost the same way)? Can the functionalities be addressed by another (existing) application with enhanced customization? Note: the above queries are best answered by the client's business team and the client's industry domain SME. Version Compatibility — Verify the Product Compatibility matrix and documentation w.r.t. technology stack, compliance with the cloud platform, and ensure those can be supported in the target cloud architecture. Each cloud follows a set of security standards and policies supported level of software/technologies. Similarly, the cloud also should support various regulatory compliance w.r.t. client’s industry domain. In general, the OS, middleware, etc., are supported up to N-1 level where N is the latest GA (general availability) release of system/software component. Vendor Support of Product — Check if the vendor has a roadmap for supporting the on-prem hosted product version. It also needs to be verified if the existing system requirements of the product are supported in the target cloud. This may lead to an upgrade before migration. Some vendors, as part of digital transformation, take multi-tenant and software-as-a-service approaches and may force customers to adopt the same for the product. SaaS-Adoption — Does the product has SaaS, and if so, is that acceptable to the client w.r.t Data Privacy and security? Also, one should do a cost evaluation compared to a hosted solution. Verify that SaaS offering support required integration with existing interfaces as well as user accessibility (authentication/authorization) and security. System Integration Landscape — The current product may use an integration style/protocol/port with internal/external systems. As the product is now planned to be on the cloud, the same protocol /port may not be supported as per security standards and may need a separate cloud-specific port. Sometimes, this may lead to a re-design of the product itself which is rare to achieve within the timeline. Most of the time, in this scenario, exceptional approval has been achieved from CSO (chief security office) for existing ports to be allowed over the cloud. Resource Optimization — For business-critical applications, it’s an important architecture decision to have a cost-effective approach towards scalability, availability, improved fault tolerance, and faster deployment. Moving to container will help in all these aspects; however, the COTS product image needs to be ‘lightweight’ and secured. So, one needs to check if the product can be hosted on a container and if has a secure image registered in an official registry approved by the product vendor. Migrating to a container-based approach require extensive integration effort and security/penetration testing. File-Based Integration — The existing and target configuration of file share depends on the protocol supported (SMB, NFS, DFS, etc.) and whether both systems (publisher and consumer of files) within the same network domain. In target, the domain of participating systems will be different networks by the underlying hypervisor. This also needs specific ports of communication to be opened between the cloud and on-prem. Migration Path — Any product migration can choose one of two paths —1) Migrate the new product to the cloud directly, 2) Upgrade the product on-prem and then migrate to the cloud. The first option poses a higher risk in terms of performance and integration as the newer/upgraded version is likely to have different interfacing, port, and technology. The initial upgrade, system, integration, required testing, and compatibility must be done on-premise with all ecosystems and get business approval. This will drastically reduce product testing and integration effort while migrating to the cloud. Implementation RACI — Once the target version of the product is decided for migration, it becomes critical to get the right SME and establish a RACI (Responsible, Accountable, Accountable, Informed) matrix. While setting up the infrastructure and required network can be done by SI (service integrator) and the cloud team, the installation, upgrade, product installation configuration, and integration need to be carried out by the product/COTS SME, who should be from the product vendor team. Generally, the SME has to be engaged from the initial conversation of the upgrade-migrate path and continue to be part of core implementation team. The SI, through the client, must raise a risk of SME availability and timeline and mitigate by the product team’s confirmation on this. For SaaS adoption of the product, the product SME must be included for integration as well as security architecture/design. Users Access Mechanism — The legacy version of many COTS products requires an older way of accessing the product — through additional security software like Citrix, F5, Array Network, FortiClients, etc. (a separate URL is used to access the application/product). This needs users' laptops/devices to install and maintain separate software, configuration, and distribution whenever required. We should look for adopting the modern version of the COTS now support https/WebAPI, which is secure and does not require an additional layer. Observability and Insight — As we take an application to the cloud, it is critical that the application generates the right level of traces, logs, and metrics so that cloud-native monitoring tools can capture and use for alerting and incident management. The product should be configurable to generate the right data, which will help building predictive algorithms (using AI/ML). This can provide actionable insight observability and will help taking proactive action to reduce downtime and ensure system health and uptime. So, it is important to adopt the suitable (easily configurable to send logs, set traces, levels, etc.) product version for migration/modernization target architecture.

Hierarchy in MDM: What and Why

Aggregated on: 2023-03-13 18:14:56

What Is Hierarchy? In master data management, hierarchy management is an essential component. It allows a comprehensive view of different domains within an organization. It links the relationship among customers, suppliers, products, locations, and other entities within the business. Hierarchy Used in Different Master Data Domains Hierarchy in MDM is used in several domains, such as party master data, location master data, and product master data. Party master data includes the company, business contacts (customers, suppliers, and related business partners), and individuals (employees, customers, and contractors). It deals with customers, providers, and other business entities. The accounts are settled in the department, legal representatives, and parent organization sequence at the national level; and then at the global level. Location master data occupies the external hierarchies around the globe ranging from continents to the down level to streets and buildings. In contrast, internal hierarchies include geographies such as sales districts and different regions in the organization. Product master data is related to external and internal products. External products may be UNSPSC, HS, ETIM, etc. Contrarily internal products are linked to reporting, purchasing, and sales of products, etc.

Guarding Against Threats: Examining the Strengths and Applications of Modern Security Models

Aggregated on: 2023-03-13 13:14:56

In the world of computing, security plays a crucial role in safeguarding resources. Over the past decade, various security models have been created to ensure the confidentiality, integrity, and availability of information. They present methods that organizations can adopt to establish formal policies for information security. These policies aim to provide a structured approach for deploying security measures and practices to safeguard sensitive information and prevent security breaches. Having knowledge about different security models, their features, and their suitability for specific situations is crucial. It enables one to make informed decisions on selecting the appropriate security model that can effectively address security concerns and protect computational resources. Access Control Models One of the most utilized models, Access Control, is designed to assist in the creation of policies related to system/user-level access for diverse resources such as files, databases, and networks. The rule of thumb is to only provide access to the entity that they need to perform their duties. This model encompasses three main types of controls; Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-based Access Control (RBAC). With DAC, a resource owner has the capability to decide 'who can access what?'. For example, the owner of a file decides who they want to grant access to and in what capacity (editing or viewing rights). Due to its versatility and ease of use, the DAC model is commonly adopted by smaller organizations.

Facial Recognition and Identification in Computer Vision

Aggregated on: 2023-03-11 18:44:55

Rapid development in machine learning and AI technologies have made significant progress in computer vision for object detection and recognition. Yet creating a system that can recognize humor and amusement in people is still a challenging problem for programmers, since comedy and entertainment are subjective and based on personal tastes and cultural context. Thus, it is tricky creating a system that can precisely determine what individuals find amusing or enjoyable. However, computer vision in facial recognition and identification has made significant progress, widely employed in various applications such as security, surveillance, and biometrics. Facial recognition technology mainly identifies individuals by analyzing and comparing their facial features to a database of known faces. Facial identification involves matching a person's face to their identity. It employs algorithms to extract face characteristics like the distance between the eyes, nose curves, and the angle of the jawline to generate a distinctive facial signature.

How To Create a Failover Client Using the Hazelcast Viridian Serverless

Aggregated on: 2023-03-11 12:29:55

Failover is an important feature of systems that rely on near-constant availability. In Hazelcast, a failover client automatically redirects its traffic to a secondary cluster when the client cannot connect to the primary cluster. Consider using a failover client with WAN replication as part of your disaster recovery strategy. In this tutorial, you’ll update the code in a Java client to automatically connect to a secondary, failover cluster if it cannot connect to its original, primary cluster. You’ll also run a simple test to make sure that your configuration is correct and then adjust it to include exception handling. You'll learn how to collect all the resources that you need to create a failover client for a primary and secondary cluster, create a failover client based on the sample Java client, test failover and add exception handling for operations. Step 1: Set Up Clusters and Clients Create two Viridian Serverless clusters that you’ll use as your primary and secondary clusters and then download and connect sample Java clients to them.
