Every organization that wants to deliver the services that customers and employees demand must protect its network. Ultimately, it protects your reputation.
"Networking security" refers to any activity designed to protect the usability and integrity of your network and data. It includes both hardware and software technologies. It consists of the policies and practices adopted to prevent and monitor unauthorized access, misusage, modification or denial of network accessible resources.
Network security combines multiple layers of defenses. Here are some approaches:
- Each network security layer implements security policies and controls such as what services are allowed to be accessed by the network user
- Advanced Malware Protection (removing viruses, worms, Trojans, ransomware and spyware)
- Application security (holes, or vulnerabilities, that attackers can use to infiltrate your network)
- Behavioral analytics to detect abnormal network behavior
- Data loss prevention (DLP technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner)
- Email security (blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data)
- Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet, by using a set of defined rules to allow or block traffic.
- An intrusion prevention system (IPS) also scans network traffic to actively block attacks.
- Mobile device security etc.
- Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier.
- A virtual private network encrypts the connection from an endpoint to a network, often over the Internet.
- A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. Wireless security.
