Serverbreachcase-Canada

Server breach case - Canada

» System breached through remote desktop service, used by clientfor smaller office

» Router was not properly configured AND no proper firewall used

» Multiple hackers able to breach security with brute force attack

» Initial breach symptoms not properly understood by management

» Eventually lost all their data over their busiest time of the yearAND required a complete rebuild

» Unable to access any systems including payroll, email, clientmanagement software etc.

What we are seeing

» Cyber awareness is very low for both management & employees

» 85% of cyber incidents we have dealt with have been ransomware

» 98% of victim organizations did not have commercial AVsoftware

» 99% of victim organizations did not have sufficient data backup

» 100% of victims used outsourced IT contractors

» 99% of infected computers were Windows based

» In more sophisticated hacks, time to discovery is months or longer

» Low level of knowledge on cyber insurance

What we are seeing

Network Perimeter Security

Traditional responses to cyber threats havebeen IT based and focused on what we canbuild to protect our systems and the datathey contain. Network Perimeter Security

Recently the focus has changed to a morecomprehensive approach – cyber threats are abusiness issue, not an IT issue.

Forward thinking organizations tend to view theproblem differently.

What is out there that we should worry about?

What information and data assets do we have thatneed protecting?

Where are the weaknesses in our system?

Where should we focus our resources tomaximize the impact?

Network Perimeter Security

Perimeter defence is obsolete

Defence in depth or layered defence

Awareness

Staff training – the human firewall

Adequate backups (offline & physical)
