A network baseline is the honest portrait of your network’s daily life. It’s the predictable hum of email traffic at 9 AM, the steady stream of database queries, the normal chatter between your servers. Without this picture, every minor fluctuation…
You notice a strange spike in server traffic at 3 AM. A credit card charge appears from a country you’ve never visited. These are anomalies, and statistical anomaly detection models are the simplest, most explainable way to find them. They…
You need to see what’s wrong with your network before it breaks. Network anomaly detection methods are the tools that let you do that. They sift through the constant hum of data, looking for the odd blip, the strange pattern,…
You look at a vast collection of data, and something just feels off. There’s a pattern that shouldn’t be there, a blip that breaks the rhythm. Unsupervised learning anomaly detection is the art of finding those blips without a manual. …
Anomaly detection techniques in NTD is your digital smoke alarm. It doesn’t wait for a known fire, it sniffs out the first hint of smoke. We use it to find the strange, the unusual, the patterns in network traffic that…
Tuning signature based alerts is the essential process of adjusting your IDS/IPS rules to stop the flood of false alarms and start catching real threats. If you’re tired of sifting through hundreds of irrelevant alerts to find the one that…
Compensating controls for signatures are your backup plan when you can’t use the best security method. They are different safety steps you take to make sure a signature is still safe and legal. You might need them because your computer…
When it comes to protecting networks, signature-based systems like IPS and IDS often feel like the first line of defense. But attackers have grown cleverer, using signature evasion techniques that tweak or mask their malicious payloads to slip right past…
When it comes to catching malware, detecting known malware signatures remains a cornerstone of cybersecurity. At its core, this method compares suspicious files or network data against a vast database of malware fingerprints , unique patterns that identify malicious software. …
When it comes to zero day threats, the challenge is clear: they’re unknown vulnerabilities, which makes them nearly invisible to traditional defense tools. We’ve seen firsthand how these threats slip through signature-based systems and linger undetected for weeks, sometimes months.…
