Layered defences , including the application of secure access solutions , can help fortify your network against ransomware threats .
Data Keeper gives users free access , allowing them to customise their malware . Once it has been generated , Data Keeper shares the profits with its users every time their ransomware successfully claims a victim .
These developments are striking and ransomware gangs are likely to refine their tactics and technology in the years to come . These illicit innovations notwithstanding , what worked in 2016 will work in 2018 .
Any strategy to deal with ransomware must extend to every level of your environment , from your endpoints , IoT devices and email gateways right through to your data centres and cloud resources . A layered approach , with secure access , active endpoint security and network visibility , will effectively reduce endpoint security threats and increase fidelity to discover and mitigate malware activity .
If a user has inadvertently disabled their endpoint security , such as their personal firewall , or if their anti-malware protection is out of date , secure access solutions can identify this threat . If that user clicks on a phishing link and infects their company-owned laptop with a case of SamSam , a Network Access Control solution could prevent that infection hitting the company network and infecting more endpoints . And a network monitoring , firewall or web proxy solution could identify command and control communications to known malicious sites controlling the ransomware .
When ransomware hits your network , it is going to try to identify as many systems as it can to exploit vulnerabilities , gain control over system and invoke encryption and data exfiltration as much as possible . A layered approach will allow you to more efficiently isolate infected systems , possibly to its patient zero , quarantining the compromised endpoints and preventing malware before it can materially spread or attack .

Layered defences , including the application of secure access solutions , can help fortify your network against ransomware threats .

Better yet , it will help make an attackers job that much harder . While ransomware authors are always finding ways to work around security solutions , enhancing security mechanisms at different areas of your environment will give a ransomware attack group more obstacles than it can handle . However , security must still support the smooth operation of a network and its constituents , so any layered security solution will have to allow seamless accessibility , protection and resource availability for users .
Layered defences , including the application of secure access solutions , can help fortify your network against ransomware threats , automatically isolating its propagation and killing malicious activity quickly before it can infect the whole network and wreak damage . u
