At its core, a firewall is a protect that protects your community from malicious site visitors. Sounds easy, however those that work with firewalls each day know the truth: A mean firewall has 1000’s of guidelines governing how site visitors must be dealt with, lots of which can be outdated, redundant, or contradictory. In reality, a Cybersecurity Insiders report revealed that 58% of organizations have greater than 1,000 firewall guidelines, however we all know of shoppers with extremely advanced environments the place their firewall guidelines quantity within the hundreds of thousands. Not solely is that this a complexity difficulty, however a safety threat. Gartner asserted that misconfigurations would trigger 99% of all firewall breaches by means of 2023.
It’s no shock, then, that once we spoke to our clients, there have been just a few challenges we heard again and again: (1) Checking configuration particulars is tough, (2) Troubleshooting is tough, (3) Optimizing the ruleset is tough. So, once we started working on our AI Assistant for Firewall, these have been the three use circumstances we targeted on: help (coverage identification and reporting), increase (troubleshooting) and automate (coverage lifecycle administration).
Constructed inside Cisco’s cloud-delivered Firewall Administration Middle (cdFMC) and leveraging the newest giant language fashions (LLMs), we created a generative device designed to simplify firewall administration for each seasoned admins and novice customers. Using superior pure language processing (NLP) and machine studying (ML), it offers solutions in seconds somewhat than forcing an administrator to spend their time sorting dependencies, community maps, and documentation. A change ticket which may have taken two hours to shut prior to now, might be resolved in a fraction of the time — we’re speaking minutes — due to the context-based AI.
Under are just a few examples of the Cisco AI Assistant for Safety in motion.
Help coverage identification and reporting
Think about this situation: Somebody from the SecOps crew reaches out to the firewall admin as a result of they’ve seen suspicious exercise. It seems some information is being exfiltrated from SalesApp, representing a possible information breach. Going ahead, SecOps desires all outbound site visitors to be blocked from this utility.
To start out, the firewall admin desires to know what insurance policies are already in place for SalesApp. With the AI Assistant, the admin doesn’t should kind by means of 1000’s of current guidelines manually, however as a substitute, they will ask the AI Assistant and get the reply in seconds.
Now that they’ve seen the prevailing insurance policies in place, they will ask the AI Assistant so as to add a rule blocking outbound site visitors. The AI Assistant recommends a rule, which might be authorised earlier than being carried out.
Increase troubleshooting
Subsequent, let’s think about your firewall rule engine retains restarting for an unknown motive. The assistant can detect this difficulty and suggest decision steps – on this case, updating the Vulnerability Database (VDB). Not solely does this remove the necessity to search by means of documentation or create a help ticket, however the Assistant is taking proactive actions.
Automate coverage lifecycle administration
Lastly, the coverage evaluation and optimization options constructed into the AI Assistant can discover duplicates and counsel a plan of action to assist with coverage hygiene. On common, our clients discovered that 29.7% of their guidelines want adjustment. For one buyer, that equaled over 17,000 guidelines.
Assuming an admin may manually discover and resolve these points inside one hour at $56/hr, this group stands to avoid wasting $971,040 over guide optimization efforts and eight.3 years of time.
Optimize by means of suggestions
To offer the very best quality expertise for purchasers, we’re additionally targeted on optimizing the AI Assistant by means of user-provided suggestions — serving to the AI Assistant study and enhance over time.
Extra AI improvements forward
The AI assistant is greater than only a comfort; it represents a paradigm shift in how we configure, handle, and guarantee efficacy for firewalls — the true spine of community safety.
Whereas that is the primary occasion of the AI Assistant for Safety, it received’t be the final. We’re injecting Generative AI and unifying telemetry throughout all Cisco Safety options to create a simpler expertise and safeguard our buyer’s enterprise.
The Cisco AI Assistant for Safety will probably be Usually Accessible (GA) for our Firewall clients within the Spring of 2024 for gratis through the cloud-delivered Firewall Administration Middle (FMC) and increasing to different administration instruments sooner or later. Be taught extra about how the AI Assistant for Safety works with our Firewall.
