IT Infrastructure and Application Security Services

The current pace of digital transformation and technological evolution has heightened the need for robust cybersecurity. Malicious actors are constantly trying to pry into the increasing volume of digital data. If not securely implemented, software can be hijacked to leak data or transfer code to unauthorized parties. Stringent policies, established best practices, and dedicated security professionals work together in ensuring data confidentiality, integrity, and application availability.

Security Posture Assessment

Implementing cybersecurity begins with defining the organization’s security posture. We identify vital resources of the organization, grading them by their level of risk tolerance. Based on the criticality of each resource and referencing standard security frameworks, we can draw up policies and processes to protect each of them. Periodic evaluation of the security practices with appropriate modifications to accommodate system changes will ensure a healthy security posture.

Comprehensive security involves securing your servers, databases, networks, and other IT infrastructure along with the software applications that support the business. A defense-in-depth model with multiple layers of control is the hallmark of our security strategy.

Defense-in-Depth Strategy

At the core of the security model lies the information or data protection layer while the outermost layer may involve firewalls and proxies to restrict external traffic. The multi-layered approach ensures that if one layer fails another will prevent further breach into the system.

Monitoring and Managing Network Security

Preventing and protecting your network against unauthorized intrusion or unwanted modification is integral to cybersecurity management. By applying multiple layers of defenses at the edge and in the network using policies and controls, we can prevent exploits.

Security management of any public or private network can include measures such as access control, antivirus installation, firewall management, email security, VPNs, and network segmentation. Periodic and timely backups, active directory implementation, and network redundancy also contribute to securing the network.

Network security measures often vary according to the size of the organization, nature of its business, the kind of data and systems it works with, and so on. A small business may need only a basic security management system with a standard firewall and anti-spyware software. Larger enterprises may require additional resources for effective threat management. Government networks will need strong protection implemented against unauthorized external as well as internal access. Sometimes in case of remote teams, it may even be necessary to build a secure offshore delivery center (ODC) to enforce highly strict data protection policies.

As network administrators, we assess the security needs of the organizational network and implement measures. We also take steps to manage network traffic efficiently and enhance network performance through remote monitoring.

Secure ODC Development

If you have a project that handles sensitive data, a secure ODC setup helps ensure the safety of your data that is crossing borders.

When you build your ODC with us, you can rely on our experience to plan and set up a development center meeting the security and compliance requirements dictated by the project. It could range from a physical access-restricted environment to a full-fledged development hub with a dedicated security operations center (SOC).

We use Security Information and Event Management (SIEM) solutions to collect and analyze data from across the IT infrastructure estate. The SIEM tool helps our security team detect threats, pinpoint security breaches, and investigate alerts. It can also aid us in capacity planning and maintaining regulatory compliance (PCI, HIPAA, GDPR, etc.).

A SIEM system collects logs, analyzes, and provides visualizations based on specified criteria. In the stack represented above, an agent is used to pull logs from different computing systems on a periodic basis. The logs are kept in an elastic database. This data is later analyzed to identify patterns and variations allowing early detection of threat actors and possible attack surfaces.

Server Security and Hardening

Security implementation efforts on the server layer can involve penetration testing and vulnerability assessment along with restricting public access to server variables through various hardening measures. Our IT and security testing teams work together to implement security at the server strata. Testers employ various security audit and intrusion detection systems to facilitate the scanning and analysis process while the IT operations team acts upon the inferences. Server hardening is carried out at the operating system level and the application layer.

Server Penetration Testing

The aim of a server penetration test is to identify server vulnerabilities. This can be performed with the help of different tools that augment the tester’s analysis. To assure clients of the compliance of our security processes with IT industry standards, we base our penetration test tools, assessment strategies, and audit checklists on OISSG’s Information Systems Security Assessment Framework (ISSAF). While most penetration testing services end in a final report detailing the exposed vulnerabilities and recommendations for their removal, we take the process to the next level by implementing those corrective measures.

Infrastructure Security for Hybrid and Multi-Cloud Environments

As you move mission-critical workloads to the cloud, we help you plan and build protection against data breaches by extending your security policies and measures to the cloud platforms. Our team of certified cloud security professionals will assess the security posture and implement safety measures. With strong capabilities in pragmatic risk and compliance management and multi-cloud expertise, our security consultants are well-equipped to handle the security challenges of cloud-native development and public cloud migrations.

Our main services include:

Securing the Applications

Mobile apps and web applications including IoT that exchange information over the Internet are susceptible to different kinds of hacker attacks. Applications are even more vulnerable when they share resources in a cloud environment. Application security refers to the process of designing, developing, and testing security features in these applications. To minimize vulnerabilities and prevent intrusion, you should consider security from the early stages of the software development life cycle.

Most security measures at the application level are built into the application code. For instance, data submitted by external users have to be properly validated. Access control mechanisms such as file permissions, IP restrictions, user authentication, and authorization can be strictly enforced to prevent unauthorized access. Cryptographic functions may also be used to protect confidential data. Proper logging and error handling, SSL encryption, and up-to-date third-party libraries are some of the other measures for building application security.

Our security testing service focuses on revealing weaknesses at the application level and correcting them before the software is deployed.

Database Hardening

Databases are a typical target for malicious attacks as they hold valuable information. Following established security best practices, we help prevent data theft to keep your business and customer information safe.

Hardening measures can involve physical security measures such as moving the database to a machine different from that which hosts your applications. Non-physical aspects include firewalls (both WAF and database firewall), regular patch updates, data encryption, cloud backup, and more. Once security steps are in place, periodic audits help evaluate the DB security and spot vulnerabilities. Regular monitoring and reviewing of logs can be effectively carried out with the help of database activity monitoring (DAM) tools.
