With Ransomware attacks becoming increasingly frequent, we thought of putting together a list of technologies that can help organizations protect themselves against ransomware attacks. Please note that even though this blog discusses technology measures, this does NOT mean people & process are secondary. There’s no single technology that can protect against ransomware, and for effective defense a combination of technologies along with right processes and skilled security professionals is a must. Here’s the Technology Stack for Ransomware Protection:
Technologies for Ransomware Prevention
- Security Awareness & Training – One of the most effective ways to secure any organization. Continuous security training & simulations can help reduce the risk significantly.
- Vulnerability Assessment & Patch Management – Continuous VA & Patch Management is a very effective measure. Remember if people had patched their Windows after Microsoft released the patch for EternalBlue, they’d be protected against WannaCry.
- Perimeter Security
- Email Security Gateways – Email being one of the most common channels used to spread malware, requires a strong focus. Organizations can also consider dedicated email ATP technologies from major security vendors.
- Web Security Gateways – Prevent drive by attacks and infections from visiting infected websites
- Endpoint Security
- Anti-Virus (AV) / Endpoint Protection Platforms (Next Gen AV if you like): Platforms based on machine learning will serve the purpose better than traditional ones. There are even dedicated Ant-Ransomware solutions out there.
- Application Whitelisting – There are dedicated solutions out there for this, as well as AV solutions and OSes with this capability.
- Port Control – Restrict USB access by using solutions like Group Policies
- Backup – A multitude of backup solutions exists, choose the one that suits your need so that you can quickly restore in case of an infection. Make sure that the backup is not infected. If taking cloud / network backup, do not map it as a network drive
- Network Sandboxing – Helps analyze malicious files / payloads if they bypass the perimeter controls or can augment perimeter security controls
- Network Segmentation / Micro-segmentation – A number of solution exists and infection in one segment will not spread to others if properly implemented
- Browser Protection
- Ad-Blocker – you probably already have this, check out the browser store in case you don’t have this.
- Browser / Application Virtualization – Will prevent machine infections from malicious websites as the Application (Browser) is running in a virtual instance
- Technologies for Ransomware Detection – i.e. Before you Seen the Demand for Bitcoins
- Endpoint Detection & Response – Detect infections which have evaded your AV and other security controls
- Honeypots & Deception Tech – Strategically placed decoys or honeypots (files, devices etc.) across the IT infrastructure can help detect ransomware before it causes any significant damage
- File Integrity / Activity Monitoring (FIM) – Monitoring file integrity on devices can generate early warning signals to act on
- Threat Intelligence (TI) – TI feeds fed into SIEM, IPS/IDS, Perimeter Security and other solutions can help provide both prevention and early detection of threats
- SIEM – The one solution to rule them all, enough said
- HIPS / IPS / IDS with Exploit Kit Detection – Some may have FIM capabilities built in
- UBA / NBA – Behavioral analytics at network / endpoint level can provide early signals of possible infections
And of course, a number of APT Security / ATP / ATA Solutions.
