Ransomware attacks pose a major cybersecurity threat - but there's action that can be taken to stop the cyber criminals from making you their next victim.

Defending against ransomware attacks and other cyber threats takes more than just setting up detection measures to identify potential malicious activity. Cybersecurity teams need to ensure that the network is made unattractive to cyber criminals by making it difficult to break into in the first place.

Ransomware is a major cybersecurity problem facing organisations around the world, as cyber criminals break into networks, encrypt files and servers, and then demand a ransom payment that can amount to millions of dollars in exchange for the decryption key. This is often combined with stealing data and threatening to release it if a ransom isn't paid.

According to Microsoft, the rise of ransomware-as-a-service (Raas) – kits developed and sold on dark web forums that allow people with minimal technical knowledge to launch ransomware attacks – is lowering the barrier for entry and causing challenges for network defenders.

Microsoft: Cyber Signals: 3 strategies for protection against ransomware

by Vasu Jakkal - August 30, 2022
The “as a service” business model has gained widespread popularity as growing cloud adoption has made it possible for people to access important services through third-party providers. Given the convenience and agility of service offerings, perhaps it shouldn’t be surprising that the “as a service” model is being used by cybercriminals for nefarious purposes.

Because cybercriminals rely on security vulnerabilities they can exploit, companies can help block attackers by investing in integrated threat protection across devices, identities, apps, email, data, and the cloud.

Here are three major strategies to help protect your environment from RaaS attacks:

Prepare to defend and recover: Adopt a Zero Trust approach, which means never trusting an identity but instead always fully authenticating, authorizing, and encrypting every access request before granting access. This strategy also involves taking measures to secure your backups and protect your data.

Protect identities from compromise: Safeguard network credentials and prevent the lateral movement used by attackers to evade detection while moving through your organization in search of assets to exfiltrate or destroy.

Prevent, detect, and respond to threats: Leverage comprehensive prevention, detection, and response capabilities with integrated security information and event management (SIEM) and extended detection and response (XDR). This means understanding typical attack vectors, like remote access, email and collaboration, endpoints, and accounts, and taking steps to prevent attackers from getting in. And, very importantly, ensure that along with outside-in protection you are also doing inside-out protection focused on data security, information protection, and insider risk management.
