Network vulnerability scans play a crucial role in safeguarding networks. The process involves both external vulnerability scanning — a scan from the outside to check your network’s firewall and other “perimeter” defenses — and internal vulnerability scanning — a scan that tests every device on your network. Internal vulnerability scans not only look at your servers and workstations, but also check laptops, mobile devices, printers, network phones and anything else on your network.
Just like everyone needs to get periodic dental X-rays, every computer network needs periodic vulnerability scanning. With X-rays, the frequency depends on the patient’s hygiene, existing condition of the teeth, prior dental work and other conditions.
