CIS Palo Alto Benchmarks

As part of a good security management program, the networking teams need to ensure a consistent configuration baseline for Palo Alto appliances across the network. Even the most well managed networks have misconfigurations within infrastructure devices that can leave these systems at risk for attack or exploitation. The Center for Internet Security (CIS) is an organization that works with security experts to develop a set of best practice security standards designed to harden operating systems and applications. This report provides a high-level overview of results gathered from CIS compliance scans using the CIS Palo Alto Benchmarks.

SC Dashboard

ICS Vulnerability Summary

When assessing ICS/SCADA Environments , organizations must ensure systems linked to critical equipment and infrastructure are secure and out of reach of potential bad actors. Unfortunately in an OT environment active scanning may be detrimental to normal operations and therefore passive scanning is key. This dashboard leverages information collected passively within the network, which assists security teams in measuring and reducing cyber risk.

SC Dashboard

ICS Asset Detection

When assessing an ICS/SCADA Environment’s security posture, one of the first steps is to identify Hosts running across the network. Unfortunately, in an OT environment, active scanning may be detrimental to normal operations and therefore passive scanning is key. This dashboard leverages information collected from Tenable Industrial Security on passively detected operating systems within the network, which can assist security teams in measuring and reducing cyber risk.

SC Dashboard

ICS Network Utilization and Topology

Understanding the network topology is a critical first step in understanding the security posture of an ICS/SCADA environment. Due to the criticality of the ICS/SCADA devices, these devices cannot be scanned using traditional active scanning methods. This dashboard leverages information collected from Industrial Security to passively detect operating systems, protocols, and applications used on the ISC network.

Tenable.io Report

Critical and Exploitable Vulnerabilities Report

Identifying, prioritizing, and patching existing vulnerabilities on a network is a key practice in reducing an organizations cyber risk. By determining which vulnerabilities are most severe, analysts can properly prioritize vulnerability remediation in order to best protect systems on the network. This report presents a comprehensive look at the critical and exploitable vulnerabilities discovered on the network, which can be useful in reducing the overall attack surface and keeping critical data secured within an organization.

CIS Desktop Application Compliance Reports

Hardening operating systems is a key component to a risk management strategy. However, applications should not be overlooked. Applications such as internet browsers and office suites can be configured in such a way as to reduce overall risk to the organization. The Center for Internet Security (CIS) is an organization that works with security experts to develop a set of 'best practice' security standards designed to harden operating systems and applications. This report provides a high-level overview of results gathered from CIS compliance scans using the CIS Desktop Application benchmarks.

ITSG-33: Audit Details

Organizations that must comply with ITSG-33 controls need a consistent and structured way to validate compliance. Failure to comply with federal compliance standards could put the organization at risk for data theft, network compromise, or non-compliance. Using this dashboard, analysts will see a clear and consistent representation of the organization measured against the ITSG-33 controls.

SC Dashboard

ITSG-33: Authentication and Access Control

As organizations comply with mandatory regulations, a method used for user account management emerges in some form to align permissions with the recommendations in the regulation. User accounts should follow organizational standards, but some accounts may not be in line with expected permission levels or even may be compromised. This dashboard assists analysts with keeping user accounts in line, and validates organizational user standards with Canada’s ITSG-33 guidelines.

SC Dashboard

Understanding Risk

Organizations spend a lot of time addressing vulnerabilities and whether or not they should be remediated or mitigated. Analysts may not be aware of what vulnerabilities have the biggest risk to the organization and where to best focus their efforts. This dashboard can assist analysts by providing information on what remediated vulnerabilities can better reduce risk to the organization.

ANSSI XI: Organise Response in the Event of an Incident

Many organizations do not have adequate incident response plans in place to deal with infected machines and network compromise. This dashboard aligns with Section XI of the ANSSI 40 Essential Measures for a Healthy Network guide: Organise Response in the Event of an Incident. Organizations will be able to use the information presented to understand current weaknesses and how to fix them, detect compromised hosts, and track incident response activity.
