title="Posts by Gayathri Nagarajan" rel="author">Gayathri Nagarajan</a> </p> </div> </div>  <div class="entry-content"> <p>Firewalls are a critical line of defense for any organization’s network security. But as companies grow and the threat landscape evolves, managing these firewalls becomes increasingly complex.</p> <p>Security teams often find it <strong>challenging </strong>to stay updated with the ongoing changes and adjustments required for firewall settings and rules to adapt to new threats, network changes, and compliance requirements. Often this leads to security gaps and vulnerabilities if not managed correctly.</p> <p>One of the main risks associated with firewall management is <strong>misconfiguration</strong>. The process of manually reviewing and configuring firewalls is not only laborious but also susceptible to human error, which can create exploitable weaknesses in a network’s defenses. Gartner has forecasted that misconfigurations will account for 99% of firewall breaches by the year 2025, highlighting the need for a more reliable and automated management solution.</p> <p>Additionally, the cybersecurity industry is facing a <strong>skills shortage</strong>, making it difficult for organizations to hire professionals who possess the depth of knowledge required to leverage all the features a firewall offers. This shortage can lead to security tools being <strong>underutilized</strong>, meaning that companies aren’t seeing the full potential <strong>return on their investment</strong> in these technologies.</p> <p>Lastly, traditional firewall management tends to be <strong>reactive </strong>rather than <strong>proactive</strong>. Security teams often find themselves in a position where they are addressing issues after they have already arisen, rather than anticipating and preventing them. This can lead to costly downtime and security breaches.</p> <p>These challenges highlight the need for a new approach to firewall management.</p> <h2><span style="color: #6abf4b;"><strong>What is AIOps for Cisco Firewalls?</strong></span></h2> <p>Imagine your firewall fuelled by AI and machine learning (ML) that involves correlating data, predicting issues, identifying reasons for failure or potential failure with data, providing recommendations, and then automating tasks to enhance overall efficiency and security. That’s essentially what AIOps for Firewalls is!<strong> </strong></p> <p>AIOps analyses massive amounts of data like firewall logs, alerts, metrics and network activity patterns using various range of models and can detect complex patterns, guide remediation efforts, and even automate responses to enhance both efficiency and security.</p> <p>Traditional firewall management is reactive, but AIOps takes a proactive stance. It anticipates problems before they happen, preventing downtime and headaches.</p> <p><strong>Think of it like this:</strong> Imagine your car with advanced driver-assistance systems that warn you about lane departures. AIOps for Firewalls is like having a self-driving car for your cloud and network security. It continuously monitors your configuration and traffic, identifies potential hazards such as usage spikes, misconfigurations, best practices, and security threats, and guides you to take corrective actions to keep your system secure.</p> <h2><span style="color: #6abf4b;"><strong>Our Approach: The Path to an Autonomous Firewall Future</strong></span></h2> <p>Like Tesla’s journey towards self-driving cars, Cisco is on a quest to infuse its AIOps for Firewalls with greater intelligence and automation.</p> <p>You can expect an era of intelligent alerting where the system delivers clear, actionable alerts that cut through the noise, prioritizing the most critical issues and conveying a sense of urgency where needed. This means an end to the flood of irrelevant notifications, enabling security teams to focus on what truly matters. Its <strong>smart event correlation</strong> will connect disparate events to highlight unusual patterns, improving threat detection.</p> <p>Furthermore, AIOps will detect anomalous behavior using dynamic baselines and offer <strong>forecasting abilities </strong>to predict and prevent potential issues using multiple advanced forecasting models.</p> <p>It will also provide <strong>precise remediation suggestions </strong>powered by GenAI , assisting in rapid problem resolution. Ultimately, the goal is to achieve <strong>self-healing</strong> or <strong>automated remediations</strong>, minimizing the need for human intervention and ensuring consistent network uptime and security.</p> <p><a href="https://storage.googleapis.com/blogs-images-new/ciscoblogs/1/2024/05/xrdctfvygfctdxrsze.png" target="_blank" rel="noopener"><img class="aligncenter wp-image-457733" src="https://storage.googleapis.com/blogs-images-new/ciscoblogs/1/2024/05/xrdctfvygfctdxrsze.png" alt="" width="800" height="533" srcset="https://storage.googleapis.com/blogs-images-new/ciscoblogs/1/2024/05/xrdctfvygfctdxrsze.png 972w, https://storage.googleapis.com/blogs-images-new/ciscoblogs/1/2024/05/xrdctfvygfctdxrsze-300x200.png 300w, https://storage.googleapis.com/blogs-images-new/ciscoblogs/1/2024/05/xrdctfvygfctdxrsze-768x512.png 768w" sizes="(max-width: 800px) 100vw, 800px" /></a></p> <h2><span style="color: #6abf4b;"><strong>The Benefits for You</strong></span></h2> <p>Imagine a world where your business operations are rarely interrupted by network outages/downtime.
