Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

Security

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.
