Mark Ellis

Cyber Security Consultant

Citrix Consultant

Digital Harmony Australia Pty Ltd

I have a Masters Degree in Cyber Security, over 50% of a Computer Science Degree (ongoing study), Citrix and Microsoft qualifications, and 30 years’ experience working as a Systems Engineer.

I am based near Cessnock in the NSW Hunter Valley. I normally travel to site anywhere in Australia, spend time on-site collecting information, then return home to write up reports or deliver agreed work remotely.

Services I Offer

I can deliver a military grade solution to keep your most secure data and communications safe.
Review of security architecture. I have experience at a senior level in very high security environments.
Cyber Security audit using the NIST framework.
Identify security weaknesses and points of risk.
Cost optimisation. I can review your current operations and advise on removing waste, inefficiency and duplication of effort or software.
Set up systems monitoring to collect the data to make data backed decisions.
Manage projects. I can get people moving and get results. Technical skill and experience can make a big difference when managing a project. I am not afraid to have “difficult conversations” if required.
Microsoft Server Security Hardening. Remove unused software and disable unused services and features. This reduces the attack surface of servers. There is nothing to buy or add and yet so few people attempt it.
Use Microsoft AppLocker, a feature you already own, to do whitelisting of your Microsoft servers.
Create AD Policy to deploy a set of Microsoft Firewall rules that blocks data collection by well-known offenders.
Optimise profile management, including browser cache and OneDrive behaviour.
Network printer optimisation.
- Optimise drivers. A single bad driver can damage your whole printing system.
- Minimise print job “tromboneing” where print jobs traverse the WAN more than they should. It is really common for a user in a branch office print to a printer across the room but the print job goes via the WAN to the corporate print server and back out to the branch office. (You double your network traffic charges if it goes into the cloud.)
I can fix all your Citrix or Remote Desktop Services problems. I am really good at Citrix.
- Citrix & RDP Printing,
- Fix applications that won’t run on Citrix or Remote Desktop Services.
- PVS and MCS
- Citrix & Remote Desktop Services Profile and cache management.
Write or update security policies.
Design and deliver Cyber Security training to staff.
Studies have found 65% of hacking attempts are internal. Whether this is a departing employee wanting to take a client list with them to a new employer, to an employee wanting to harm your company due to ‘ideological differences’.
