The hackers are hitting Cisco ASA devices more than what has normally been seen, and this has security teams worried.
When hackers scan these devices, they are looking for vulnerabilities. This is like a thief walking down a road pulling on car door handles looking to see which ones are unlocked.
I recall a situation at my home. I set up a small firewall and the logs showed that strangers were scanning almost daily. That was enough for me to bolster security. For a firewall like the Cisco ASA, the stakes are much higher.
What Should Administrators Do?
For those who use, here's a simple checklist to help keep secure:
• Install updates and patches immediately as they are released.
• Restrict remote access and use strong passwords.
• Enable multi-factor authentication (MFA).
• Monitor logs regularly and look for anomalous traffic.
• Disable services you do not need.
Most compromises happen because someone skipped one of these essentials.
Should you be afraid? No. Should you act on this now? Yes!
What Are Cisco ASA Devices?
Cisco ASA (Adaptive Security Appliance) devices are like gateways to a company network. They act as a firewall and VPN that keeps out bad traffic while allowing good traffic in.When hackers scan these devices, they are looking for vulnerabilities. This is like a thief walking down a road pulling on car door handles looking to see which ones are unlocked.
Why Is This A Problem?
You might say "But isn't scanning just background noise?" It is true that some scans are totally random. However, when hackers consistently focus on scanning Cisco ASA devices, it indicates they found or are looking for a new vulnerability.I recall a situation at my home.

What Does This Spike Mean?
With an increase in scanning this much, it typically indicates that malicious actors are preparing for a more significant attack, and they may already have a target or know of a vulnerability and are looking for devices that have not been patched.Should you be afraid? No. Should you act on this now? Yes!
