DDoS prevention is a hot topic. DDoS attacks have become a weapon of choice for malicious actors to conduct cyberattacks. I did a posting on Defending Against Apache Web Server DDoS Attacks and contributed to a DDoS: Proactive and reactive measures document from CERT.be.
One of the mitigation measures that you can apply is doing country based IP filtering. This basically limits access to your network from a limited set of prefixes. I consider this … Read more.
I recently had a presentation and information session for human right activists on how to secure their group communication and data sharing.
