Your digital footprint is made up of everything piece of information you provide online. from your name gender, email address to emails, website you visit and things you say or like on social media. Because the actions we take online say a lot about us, it is impor...

Frameworks > IT Security

We provide security assessments based on the following acceptable frameworks and standards:

* ISO/IEC 27000

This international standard provides a series of best practices to help organizations improve their information security.
- ISO/IEC 27001 is a key element of the series. It explains the best practices in information security and is the only element in the series that organizations can be audited and certified against.
- ISO/IEC 27002 is a supplementary standard to that discusses the information security controls that organizations might choose to implement.
- ISO/IEC 27017 and ISO/IEC 27018 are supplementary standards explaining how organizations should protect sensitive information in the Cloud. ISO 27017 is a code of practice, providing extra information about how to apply security controls to information stored in the Cloud. ISO 27018 works in essentially the same way but with extra consideration for personal data.
- ISO 27701 is also another supplementary standard covering what organizations need to do when implementing PIMS (Privacy Information Management Systems)

* NIST Special Publication 800-53

Although the NIST Special Publication 800 series is not specifically an information security framework, other frameworks have evolved from the NIST SP 800-53 model. Even though it is specific to U.S. government agencies, the NIST framework could be applied in any other industry and should not be overlooked by companies looking to build an information security program.

* The NIST Cybersecurity Framework

The NIST Cybersecurity Framework for Improving Critical Infrastructure is yet another framework option from NIST. It differs from the other NIST frameworks in that it focuses on risk analysis and risk management. The security controls included in this framework are based on the defined phases of risk management: identify, protect, detect, respond and recovery. These phases include the involvement of management, which is key to the success of any information security program. This structured process allows the NIST Cybersecurity Framework to be useful to a wider set of organizations with varying types of security requirements.

* CIS Controls (formerly the SANS Top 20)

The CIS Controls exist on the opposite spectrum from the NIST Cybersecurity Framework. This framework is a long listing of technical controls and best practice configurations that can be applied to any environment. It does not address risk analysis or risk management like the NIST Cybersecurity Framework, and is solely focused on hardening technical infrastructure to reduce risk and increase resiliency.

Hello!!

In today’s threat landscape understanding the risks you, your organization and customers are exposed to is more important than ever.

Understanding the impact and what you can do to make yourself and your organization more resilient is key to protecting yourself, brand, reputation and/or sensitive customer information. Building a cyber-resilient organization can be a complex process but it’s not impossible.

Frameworks > Risk Assessments

We provide risk assessments based on the following accepted frameworks.

NIST Special Publication 800-30 rev1 Guide for Conducting Risk Assessments

This NIST publication provides guidance for carrying out risk assessments and describes the interrelationships between the various components of the organizational risk management process. This publication also provides guidance regarding the ongoing monitoring of risk within the organization.

ISO/IEC 27005

This international standard provides guidance for assessing and evaluating risk as part of an overall risk management process and is aligned with other related standards for risk assessment, management, and mitigation. ISO/IEC 27005 is a key element in the development of the Information Security Management System (ISMS) defined in ISO/IEC 27001.

Services > Vulnerability Assessment

Detecting vulnerabilities and taking corrective action is important to any information security program and essential in protecting valued data assets from internal and external threats.

Our Vulnerability Assessments include a thorough evaluation of the target systems for known and newly-discovered vulnerabilities. This assessment includes automated scanning techniques that determine any abnormal or insecure protocols, ports, services, and system configurations.

The assessment involves:

Foot Printing
Port Scanning
Services Identification
Vulnerability Identification and Research
Findings Report
Remediation Recommendations

Types of assessments:

Internal - These assessments can be conducted from an internal perspective where we approach from inside the organization, much like a disgruntled employee would.

External - We can also conduct the assessment from an external perspective where we approach from outside of the organization, much like an internet-based attacker would.
