   What is network security & why is it important?

   • Network security has three chief aims: to prevent unauthorized access to network resources; to detect and stop cyberattacks and security breaches in progress; and to ensure that authorized users have secure access to the network resources they need, when they need them. As networks grow in size and complexity, so does the risk of cyberattack.

   • Firewalls. A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
   • Intrusion prevention systems. An intrusion prevention system (IPS) scans network traffic to actively block attacks. Secure IPS appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.
   • Workload security. Workload security protects workloads moving across different cloud and hybrid environments. These distributed workloads have larger attack surfaces, which must be secured without affecting the agility of the business.
   • NetWORK security. NetWORK security is Cisco's vision for simplifying network, workload, and multicloud security by delivering unified security controls to dynamic environments.

   Next-generation firewall

   For many organizations, the first line of network protection is a next-generation firewall (NGFW). Like a traditional firewall, a NGFW inspects all incoming and outgoing network traffic and creates a barrier between internal and external networks based on trust principals, rules and other administrative settings. A NGFW also includes additional features like application awareness and control, intrusion prevention and threat intelligence services. While an NGFW is a critical component within t...

   Next-generation antivirus

   Next-generation antivirus (NGAV)is a network security tool that uses a combination of artificial intelligence, behavioral detection, machine learning algorithms and exploit mitigation, so known and unknown threats can be anticipated and immediately prevented. NGAV is cloud-based, which allows it to be deployed quickly and efficiently, reducing the burden of installing and maintaining software, managing infrastructure and updating signature databases for the IT or information security team.

   Virtual private network

   A virtual private network (VPN) is a security tool that encrypts the connection from an endpoint to an organization’s network, allowing authorized users to safely connect and use the network from a remote setting. VPNs usually leverage advanced authentication methods to ensure both the device and user are authorized to access the network.
