Network Security Assessment

INTRODUCTION

RNS Technology uses proprietary scanning and reconnaissance methods, as well as other publicly available tools, to assess the security of networks and systems accessible on client networks. Service identification, host OS identification, remote language detection, and unique data interception techniques are just some of the proprietary technologies that are under constant research and development by our team.

We do full network scans on external networks to test appropriate firewall configurations. Service fingerprinting helps identify unpatched systems. Systems are also reviewed for inadequate encryption and/or authentication.

Vulnerability Assessment & Penetration Testing

As an initial step to ensure your organization’s security, we perform a vulnerability assessment.

RNS is a team of experienced professionals that has expertise in solving this kind of problem. Our engineers detect the presence of a vulnerability in an IT infrastructure through Vulnerability assessments. Also, we aggressively test for both already known and previously unknown weaknesses in your IT infrastructure architecture through Penetration Testing, exactly like an expert hacker would do, in a non-intrusive way.

RNS’s Vulnerability Assessments and Penetration Testing services are highly client focused. Clients can choose from a wide range of services described below, customized as per their specific needs.

Service Benefits

We at RNS believe in the ‘Think like the hacker to catch the hacker’ approach and hence always keep ourselves one step ahead of the threats that are continuously advancing.

RNS experts will evaluate the complete security of your IT infrastructure by safely trying to exploit vulnerabilities as a part of Penetration Testing. These vulnerabilities may exist in operating systems, services application flaws, improper configurations or risky end-user behavior. Such assessments are also useful in validating the efficiency of defensive mechanisms, as well as, end-user adherence to security policies.

Wireless Network Security​

Assumptions of many security professionals prove to be wrong when discussing wireless encryption. Resilient wireless encryption is alone not sufficient for building strong security for wireless LAN (WLAN) traffic. WPA2 encryption might stand on better authentication and encryption preferences, but WLANs can still have vulnerabilities which can cause serious problems in the network environment – these include:

  1. Rogue access points (APs)
  2. Denial-of-service attacks
  3. Attacks against WLAN infrastructure

Enterprise WLAN Solutions provide the following benefits:

  1. Business continuity: Delivers the right business tools to employees on roaming.
  2. Advanced connectivity options: Offers wired, wireless, secure enterprise mesh, remote AP, indoors, and outdoors options
  3. Identity-based security: We can enforce a unified security policy for all connected users
  4. Application-awareness: This enables us to provide optimized service delivery
  5. Reliability: Enables us to confidently use wireless as the primary network connection across the enterprise

Network Appliance Configuration Review​

Network appliances are critical for the operations of every organization, and their compromise can have a huge impact, which can be immediately quantifiable in terms of lost revenue and productivity.

A network device audit by RNS provides a comprehensive and detailed security audit of network components to ensure that weaknesses in their configurations are identified and remediated, reducing the risk of a security incident.

How can an RNS network device audit help your organization?

  1. Businesses can extend their connectivity to the optimal level and achieve operational objectives without sacrificing security.
  2. Complete support in meeting government regulations and compliance requirements
  3. Reduce the risk of network device compromise and subsequent loss of revenue and productivity.

Network Architecture Review​

With the intensifying business atmosphere and sophistication of threats, today’s network infrastructure is getting more intricate every day. Evolving critical enterprise applications and communication systems have shaped higher expectations for network accessibility and performance. Our expert consultants review the architecture of the organization’s network to develop high-level security constraints for each tier of your network and define the gaps that are requiring safety. We assist in designing a secure and robust architecture.

RNS’s Network Architecture Review is the 360-degree evaluation and analysis of existing architecture, design, security policies and practices to identify how the network architecture and controls safeguard the critical assets, sensitive data stores and business-critical interconnections in conflict with the organization’s business and security objectives.

Telecom Network Security​

Benchmarking presents information security challenges, for the telecom and VOIP sector is a constant struggle. Major errors in signaling protocols—SS7, Diameter, and GTP—and configuration errors in network equipment cause severe security threats for mobile ecosystems.

RNS Telecom Security is the complete protection of core telecom networks and systems, along with associated supporting IT platforms

Server Hardening​

Standardization and building strong server policies to keep them safe from any vulnerabilities is very important for an organization. Every business should have their Windows servers, Linux servers, SQL and Oracle database servers and firewall standards well maintained. However, to finalize an appropriate server hardening policy for a particular business environment there is detailed research required and the checklists are to be prepared for a better understanding of how this should be applied to your operating systems and applications.

RNS suggests different governance, regulatory and compliance standards such as NIST SP 800-53, NIST 800-171, CIS, SOX, NERC CIP, ISO27001, PCI DSS, DISA STIG and HIPAA all call for strong cyber security defenses, with a hardened build standard at the core. This is maintained using file integrity monitoring to highlight any significant changes or ‘drift’.

In any business, every server that is initially deployed will indeed lack the basic security defenses. This allows it to be vulnerable to threats or compromise the data. In order to mitigate potential threats, it is mandatory that servers are hardened.

Active Directory & VPN Review​

With the ever-changing IT landscape, being confident with the tools that can address your organizational needs is very critical and challenging. Microsoft’s Active Directory can be named as the most trusted directory services platform in a large number of IT organizations for more than a decade now.

RNS offers an Active Directory review for the modern IT admin, which provides assurance that the Directory controls are in place, aligned with prevailing good practice, and operating as intended and provides a measure of assurance that those external systems that are reliant upon the Directory are secure in accordance with their expectation.

We also provide management with an independent assessment of the VPN implementation and ongoing monitoring/maintenance of the effectiveness of the supporting technology.
