ConnectDS & Firewall Security Assessments

firewall security assessment

ConnectDS are cyber security specialists based in the South East of England. We perform advanced cyber security services including in-depth firewall assessments for your business to determine the current effectiveness of your network security and to ensure your cyber security measures meet the technical requirements of your business whilst complying with any required regulations.

Why are Firewall Security Assessments Vital?

Firewalls must be assessed and reviewed on an ongoing basis so that they maintain effectiveness in securing your company.

We implement measures in line with best practice and we customise our approach to your business. We operate consistently with your firewall change management and help you increase the chances of identifying weaknesses in your security systems before they become dangerous. We prevent your data from being compromised by cyber attackers.

Your firewall is your first line of defence against threats from outside your business; this is why is is essential for your firewall to be effective. Having a firewall gives you a false sense of security if skilled experts don’t configure and assess it to make sure your company is not vulnerable to the various cyber threats in play in the modern world.

What is Included in a Firewall Assessment?ConnectDS logo

Our firewall assessment service makes sure that your firewall is arranged correctly – It is a review of your current situation. ConnectDS assesses if any unnecessary rules have been set up that could expose your company’s private data. It also works out the current ruleset, to identify if rules are superseded, obsolete or may be a risk to your security. An example of these rulesets is the lack of a DENY ALL firewall rule or policy rule, or the dreaded “ALLOW ALL”!

ConnectDS’s firewall assessment service includes an evaluation of your firewall’s features and their uses so that we can identify any areas that can be more optimised. We will check whether any of these features are providing any limits to your capability and work to make these perform better.

At ConnectDS, we go the extra mile for all our clients. To make this happen, our firewall assessment moves further to technically examine the effectiveness of not only the inbound communications, but also the Egress (outbound) Traffic. We understand that the majority of modern advanced threats that occur are targeted at users, so it is important that we review the level of perimeter control to the internet from within the network. This review allows us to appreciate the risks that can take place as well as ensuring effective configuration across your company.

We make sure that your configuration aligns with best practice and to ensure the effectiveness of your firewall. ConnectDS performs all testing from a sensor within your local network; we perform a technical assessment of what is possible outbound as well as inbound, including actions such as:

  • Testing ingress and egress port and application access
  • Data Exfiltration to an external server and unapproved cloud file hosting services
  • Ingress reconnaissance and probing
  • Access to traffic anonymisation tools such as TOR (The Onion Router), unauthorised VPNs and Proxies
  • URL filtering, and access to undesirable sites such as pornography, gambling, and chat/IM
  • Ability to access online services for streaming and downloads of pirated material
  • Downloading of malicious files and viruses
  • Back door connectivity using tools including reverse port forwarding and reverse shells
  • Peer-to-Peer file sharing, to find activity such as BitTorrent that can be used for illegal activity
  • Communication through insecure protocols, including FTP, Telnet, IMAP and POP
  • Firewall base security, patch validation and version updates of threat security for threat detection modules.

ConnectDS conduct firewall audits using a specialist appliance to probe the firewall and attempt to assess and bypass restrictions currently in place.

The best firewall for your business depends on a number of factors – speak to our team to help you scope the right firewall for your business.

Unified Threat Management (UTM) Firewall is a network firewall device that also has layered security detection and prevention capibilities that can include IDS/IPS, anti-virus, anti-spam and content & web filtering.

A next-gen firewall is a conventional firewall combined with other network device filtering such as deep packet inspection and intrusion detection.

There are 3 main types of firewall:

  • Hardware firewalls – these sit at the edge of your network.
  • Software firewalls – these sit on each endpoint or servers, such as web application firewalls.
  • Cloud firewalls – this is a hosted firewall with a maintained cloud platform, also known as Firewall-as-a-Service (FaaS).

A Firewall Rule define what traffic is allowed or blocked by your companies firewall. rules are also defined for security inspection modules that are layered

To ensure maximum effectiveness of your firewall, network protection and traffic should be monitored on a regular basis and firewall configurations should be adjusted accordingly.

Traditional firewalls have many limitations compared to newer next-gen firewalls provided by ConnectDS. Due to encrypted communications there is often a lack of security visibility, this can be resolved by a layered approach to cyber security and leveraging endpoint and network data to be correlated by the ConnectDS SOC.

A great way to clean up and optimise firewall rules is with a firewall security audit.
