Network Security Assessment

Threat Detection Bundle

A network security assessment enables you to take a more informed approach to your company’s cyber-security. By having a better understanding of the challenge your business faces in terms of potential cyber threats and data security you can optimise your cyber-security measures, making them more effective and better protecting you and your company.

ConnectDS identified that the majority of security assessments are too niche for SME organisations and do not provide a comprehensive assessment of all required areas. ConnectDS have performed hundreds of security assessments and with our knowledge, we have created a fixed 30-day assessment providing a comprehensive threat detection service to technically evaluate your organisation’s internal and external risks.

Most businesses focus heavily on preventative solutions but have a lack of visibility of what’s happening in their networks, and so don’t understand the user and network activity, and whether they are already in a state of compromise. Our security assessment is a comprehensive layered approach designed to detect threats, policy violations, misconfiguration and vulnerabilities by performing comprehensive security monitoring of all activity over 30 days. 

What is CDS:30?

The CDS:30 assessment is a layered approach using a synoptic stack of forensic network security monitoring combined with multiple threat detection engines on an onsite appliance that is monitored remotely by our security analysts. The output of the CDS:30 includes the addition of a comprehensive review, validation of security alerts and threat hunting within the collected dataset. 

Our expertise in network forensics is a key differentiation as this level of assessment is typically only available to larger organisations due to the technical specialism and associated costs. These assessments are a fixed engagement designed to fully technically assess an organisation’s current security standpoint and overall resilience against cyber threat. 

Recent Findings

The CDS:30 assessment is a specialist assessment with layered security monitoring, to provide unparalleled visibility and actionable insight. The list below details some typical findings from recent assessments performed: 

  • External data exposure through unencrypted mail Traffic (SNMP/POP3/IMAP).
  • External credential exposure through Plaintext and weak encoded passwords to external services.
  • External data exfiltration via non-corporate approved cloud storage (Dropbox/Google Drive/OneDrive).
  • Internet exposed corporate and admin credentials through plaintext LDAP/AD authentication to/from external services.
  • Compromised Mac/Windows/Android devices (both personal and corporate devices).
  • Illegal downloads via Peer-to-Peer file sharing (BitTorrent).
  • Detection of bloatware and Potentially unwanted programs (PUP’s/Lenovo Superfish).
  • External data and credential exposure through unencrypted VoIP (SIP & RTP).
  • External data exposure through misconfiguration of NAS storage replicating unencrypted data between corporate sites.
  • External data exposure through unencrypted data sync to cloud platforms.
  • Vulnerable and unsupported operating systems (XP/Vista/Win7/2003/2008).
  • Vulnerable and unsupported software (Flash/Silver light/Quicktime).
  • Bypass of corporate security through unapproved remote access software on user devices (TeamViewer/LogMeIn/GoToMyPC).
  • Inappropriate business web browsing (Pornography/Gambling/Violence).
  • Detection of vulnerable wired and wireless infrastructure devices that can be exploited to provide full network access.
  • Detection of exposed “live” corporate credentials that can be used to remotely authenticate and access corporate remote access solutions. 
  • External open access to corporate CCTV systems.
  • External credential exposure through unencrypted authentication to externally hosted websites.

Protect Your Business With A Network Security Assessment

Speak to ConnectDS and discuss how our CDS:30 threat detection assessment can help your organisation gain deep visibility into your internal and external security posture validate your current policies, configurations and technical controls.

Network Security Monitoring (or NSM) is the collection and analysis of network traffic in order to identify potential policy misconfigurations, data leakage and vulnerabilities.

Full Packet Capture (or FPC) is the term for intercepting and recording data travelling across a network in order to download and analyse it.

To ensure the capture of all inbound and outbound network traffic we deploy an onside network server to function as a network sensor. The security monitoring is completely passive and collects data from a network SPAN (network mirror) or a specialist network tap that forwards the data to the sensor. As the solution is not inline there is no risk of this being a single point of failure and ensures we can perform a granular network inspection without limiting the quantity of detection rules and impacting network performance.

ConnectDS use a variety of commercial and open source tooling, with the expertise to perform granular network forensic monitoring of inbound and outbound network traffic and identify security vulnerabilities and advanced security threats.

An Intrusion Detection System or IDS is a security engine that inspects network traffic in order to detect inbound attacks and alert on them.

An Intrusion Prevention System or IPS is a security engine that inspects network traffic in order to detect inbound threats and block this traffic.

An Intrusion Prevention System or IPS is a security engine that inspects network traffic in order to detect inbound threats and block this traffic, whereas an IDS only alerts on these threats.

Continuous monitoring allows a security operations centre full visibility on an ongoing basis in order to identify vulnerabilities and indicators of compromise immediately.

Threat intelligence is any information or context relating to cyber threats and malicious threat actors used to reduce the likelihood of cyber attacks. This can be found on the internet or dark web.
