Cobalt Strike is a penetration testing tool designed for adversary simulation and red team operations. Legitimately, it's used by security professionals to test network defenses, simulate attacks, and train incident response teams on how to detect and respond to real threats. Cobalt Strike was one of the first public red team command and control frameworks.

The MITRE ATT&CK framework documents 196 individual techniques and 411 sub-techniques that help organizations understand and respond to cyber threats. Organizations have made this framework central to strengthening their security posture against evolving cyber threats since its public release in 2015.

“It takes 18 days on average for organizations to recover from a ransomware attack” – IBM Cost of a Data Breach Report 2024. The clock starts ticking as soon as ransomware hits your network. Attackers no longer rely solely on opportunistic phishing; they now attack weak network defenses, move laterally across systems, and encrypt important data before demanding a ransom. Traditional security solutions sometimes notice breaches too late to adequately detect threats.

Organizations want to stay on top of cyber threats and detect them even before they occur. To do this, they need to detect threats and anomalies in their networks as quickly as possible. This is what we call threat hunting. It is a tool to help organizations constantly monitor their networks to detect and mitigate threats to keep them at a distance.

System downtime from faulty software updates can cost businesses huge money losses every second. This reality shows why up-to-the-minute data analysis has become a vital part of modern enterprises. Companies now deal with endless data streams from countless transactions. Knowing how to spot unusual patterns right away could make all the difference between grabbing opportunities and facing harsh setbacks.

“Cybersecurity is much more than a matter of IT; it’s a matter of national security.” – Barack Obama. Data breaches are more than simply an IT concern; they may cause significant financial losses, regulatory fines, and reputational damage. Cybercriminals are always devising new ways to steal sensitive data, making it difficult for security teams to detect and mitigate these threats before they cause serious harm. This is where Network Traffic Analysis (NTA) comes in.

Machine Learning (ML) has revolutionized industries by empowering systems to learn from data, make predictions, automate decisions, and uncover insights—all without the need for explicit programming. With ML, systems can: In network security and cybersecurity, ML and other emerging technologies are crucial for detecting malicious activities such as unauthorized access, data breaches, and other complex security threats.

Companies are rapidly moving to hybrid cloud environments, with most of them already making this transition. This fundamental change affects how organizations handle their infrastructure.

To defeat the enemy, you must first disarm their ability to communicate. Command and Control (C2) attacks remain one of the most persistent cybersecurity threats, enabling adversaries to communicate with compromised systems undetected. Attackers use C2 servers to send commands, exfiltrate data, and maintain long-term access to networks. These stealthy techniques allow them to deploy ransomware, steal sensitive information, and even conduct cyber espionage.

Effective incident response is a top priority for organizations to minimize the impact of cyber threats. Quick detection and response to attacks or threats are crucial for securing the network and the organization’s overall cybersecurity posture. Incident response planning typically includes identifying, investigating, containing, eradicating, recovering, and analyzing the attack to prevent future breaches. The response times directly affect how swiftly and effectively a breach can be mitigated.

In the world of network security, understanding what’s traveling across your network is pivotal. One of the most effective tools for this task is PCAP analysis (Packet Capture analysis). Here at Fidelis Security, we’re dedicated to empowering you with knowledge and tools like our Network Detection and Response (NDR) solution to safeguard your network traffic. Let’s dive into how to master PCAP analysis.

As businesses increasingly migrate to the cloud, securing these dynamic environments has become more challenging than ever. Traditional security measures struggle to keep pace with the evolving threat landscape, leaving organizations vulnerable to undetected cloud security risks. One of the biggest challenges in cloud security is the presence of blind spots—hidden cloud security vulnerabilities that attackers can exploit.

Deep Session Inspection (DSI) is like having a security guard who watches the entire conversation between two people, instead of focusing on just a few sentences or words. Let’s see how!

Not only are cyberthreats increasing, but they are also evolving at an unprecedented rate. To bypass traditional security measures, attackers are upskilling themselves and utilizing AI-driven techniques. As former Cisco CEO John Chambers aptly put it, “There are only two types of companies: those that have been hacked, and those that will be.” This fact highlights a critical issue: legacy cybersecurity strategies are finding it difficult to stay up with emerging threats.

Along with other cyberthreats, insider threats are one of the biggest dangers affecting enterprises today. Disgruntled employees, accidental data leaks, or compromised insiders can all cause serious harm, involving monetary losses, operational interruptions, and damage to one’s reputation. According to the 2024 IBM Cost of a Data Breach Report 2024, insider-related incidents cost USD 4.99M on average.

Over the last decade, cloud computing has become the backbone of modern business, transforming how organizations operate and scale. Companies rely heavily on cloud services, with most of their applications and workloads migrating to efficient platforms like AWS due to the increased remote working requirements and demand for scalable, flexible, and cost-effective solutions that support business continuity and growth.

As cyberattacks become more complex, network detection and response solutions have become essential for modern organizations. These are more than firewalls and antivirus software; instead, they make use of advanced analytics, machine learning, and behavioral modeling to detect and neutralize threats in real time.

A recent report reveals that 98% of businesses struggle with growing complexity in their cloud and on-premises infrastructures. This complexity creates major network flow analysis challenges. Organizations report widening visibility gaps in their networks 80% of the time. The network flow problems have become more critical than ever before. Gartner’s prediction shows that by 2027, 75% of employees will use technologies their IT teams cannot see.

Cyber adversaries operate with one goal in mind—stealth. The longer they go undetected in an environment, the more damage they can cause. Dwell time is the total amount of time that a threat remains unnoticed in a system, from initial compromise to discovery. According to the most recent threat reports, the average dwell time for undetected breaches has reduced but remains at 10-15 days, providing attackers enough time to exfiltrate data, launch ransomware, or establish persistent access.
