How to Stop Ransomware

As cybercrime expands into new realms, senior leaders from small-town school districts to Fortune 50 companies are looking for better ways to protect priceless data and fend off ransomware attacks. Many organizations are now paying small fortunes to vendors making outlandish promises—even before taking relatively simple and inexpensive steps to prevent ransomware infections and respond effectively to those that do occur.

Hardening the Frontlines of Ransomware Defense

It’s possible to spot intruders and eject them from the premises, but it’s faster, safer and less expensive to stop them at the front gate. That’s the rationale for hardening external barriers to IT systems.

Cyber Risks: Web Framework Compromise

Web servers are a popular target for cybercriminals, and it can be difficult to spot that a web server’s security has been compromised. Active risk management around website architecture, maintenance, and patch and vulnerability management are essential to preventing this risk.

Mastering The Kill Chain - Step Five: Installation

Once a threat actor is able to penetrate a victim’s environment, they become all the more dangerous and more difficult to shake. This is often caused by the threat actor embedding themselves into the systems they were able to compromise to maintain their hard-earned, unauthorized access.
