  • Examine entry logs for any unusual patterns that could indicate a breach.

We're committed to making sure that our network remains secure, and a thorough examination of our ACLs is a non-negotiable part of that promise.

Firmware Update Policies

To maintain a robust defense against cyber threats, it's essential to implement a rigorous firmware update policy for our firewalls and routers. This means we have to ensure that our devices are always running the latest firmware versions, which include vital security patches and performance improvements. We've established a strict protocol for update scheduling, guaranteeing that these updates occur during off-peak hours to minimize any potential disruption to our network services.

Moreover, we don't just apply updates blindly. We've adopted a thorough patch verification process to confirm the integrity and authenticity of firmware updates before installation. This step is crucial to protect against the installation of malicious or flawed updates that could compromise our network security. By adhering to these practices, we're upholding our commitment to safeguarding our digital infrastructure.
